Damage on intestinal barrier function and microbial detoxification of deoxynivalenol:A review

Deoxynivalenol(DON)is a mycotoxin that is produced by various species of Fusarium and is ubiquitous in food and feed.At low concentrations,it can cause metabolic disorders in animals and humans and,at high concentrations,it can lead to pathological changes in the body.The impact of DON on human/animal health and animal productivity has thus attracted a great deal of attention around the world.DON causes severe damage to the intestine,including compromised intestinal barrier,mucosal damage,weakened immune function,and alterations in gut microbiota composition.These effects exacerbate intestinal infections and inflammation in livestock and poultry,posing adverse effects on overall health.Furthermore,research into biological methods for DON detoxification is a crucial avenue for future studies.This includes the utilization of adsorption,enzymatic degradation,and other biological approaches to mitigate DON's impact,offering new strategies for prevention and treatment of DON-induced diseases.Future research will focus on identifying highly efficient detoxifying microorganisms or enzymes to reduce DON levels in food and feed,thereby mitigating its risks to both animals and human health.

Detoxification strategy of Microcystis aeruginosa to the toxicity of Cd(Ⅱ):role of EPS in alleviating toxicity

Although many studies have found that cadmium(Cd)can be toxic to microalgae,only a few reports focused on the role of extracellular polymeric substances(EPS)in Cd(Ⅱ)detoxification.The biochemical and physiological endpoints of Microcystis aeruginosa,including the composition and functional groups of soluble EPS(SL-EPS),loosely bound EPS(LB-EPS),and tightly bound EPS(TB-EPS),were detected to elucidate the toxicity and detoxification mechanisms of Cd(Ⅱ)for cyanobacteria.Toxicological and physiological assays on M.aeruginosa showed that the 0.25-mg/L Cd(Ⅱ)resulted in a larger inhibition on growth and F_(v)/F_(m).Nevertheless,Cd(Ⅱ)significantly induced much higher contents of superoxide dismutase(SOD),intracellular microcystin LR(MC-LR),extracellular MC-LR,and EPS.Scanning electron microscopy with energy dispersive X-ray spectroscopy confirmed that Cd(Ⅱ)was absorbed into the EPS layer.Fourier transform infrared spectrum analysis revealed that the functional groups bound with Cd(Ⅱ)of algae biomass,SL-EPS,LB-EPS,and TB-EPS were somewhat different.The C=O/C=N groups ofδ-lactam or protein were their prominent functional groups,suggesting that amide or proteins in the EPS played a key role in the adsorption in Cd(Ⅱ).The concentration of 0.25 mg/L of Cd(Ⅱ)may change the chemical structure of EPS by altering the production of protein-like substances containing tryptophan.This study indicated that M.aeruginosa could detoxify Cd(Ⅱ)stress via induction of antioxidant capacity(higher SOD activity and MC synthesis),EPS production,and modification in chemical structure of EPS.

Simultaneous Degradation, Dehalogenation, and Detoxification of Halogenated Antibiotics by Carbon Dioxide Radical Anions

Despite the extensive application of advanced oxidation processes(AOPs)in water treatment,the efficiency of AOPs in eliminating various emerging contaminants such as halogenated antibiotics is constrained by a number of factors.Halogen moieties exhibit strong resistance to oxidative radicals,affecting the dehalogenation and detoxification efficiencies.To address these limitations of AOPs,advanced reduction processes(ARPs)have been proposed.Herein,a novel nucleophilic reductant—namely,the carbon dioxide radical anion(CO_(2)^(·-))—is introduced for the simultaneous degradation,dehalogenation,and detoxification of florfenicol(FF),a typical halogenated antibiotic.The results demonstrate that FF is completely eliminated by CO_(2)^(·-),with approximately 100%of Cland 46%of Freleased after 120 min of treatment.Simultaneous detoxification is observed,which exhibits a linear response to the release of free inorganic halogen ions(R^(2)=0.97,p<0.01).The formation of halogen-free products is the primary reason for the superior detoxification performance of this method,in comparison with conventional hydroxyl-radical-based AOPs.Products identification and density functional theory(DFT)calculations reveal the underlying dehalogenation mechanism,in which the chlorine moiety of FF is more susceptible than other moieties to nucleophilic attack by CO_(2)^(·-).Moreover,CO_(2)^(·-)-based ARPs exhibit superior dehalogenation efficiencies(>75%)in degrading a series of halogenated antibiotics,including chloramphenicol(CAP),thiamphenicol(THA),diclofenac(DLF),triclosan(TCS),and ciprofloxacin(CIP).The system shows high tolerance to the pH of the solution and the presence of natural water constituents,and demonstrates an excellent degradation performance in actual groundwater,indicating the strong application potential of CO_(2)^(·-)-based ARPs in real life.Overall,this study elucidates the feasibility of CO_(2)^(·-)for the simultaneous degradation,dehalogenation,and detoxification of halogenated antibiotics and provides a promising method for their regulation during water or wastewater treatment.

[Objectives]To explore the mechanism of Huanglian detoxification soup improving pain behavior by affecting serum IL-2 levels in postherpetic neuralgia(post herpes neuralgia,PHN)model rats.[Methods]20 PHN rats were randomly divided into model group(PHN group)and detoxification decoction group(n=10).In the group,10%Huanglian detoxification soup(0.4 mL/0.1 kg)was given once in the morning and evening for 14 d.The PHN group was filled with an equal volume of 0.9%sodium chloride solution.Tail vein serum inflammatory factor interleukin-2(IL-2),IL-βand IL-6 levels were measured using ELISA kits at 7 and 21 d.[Results]IL-2 increased at 14 and 21 d in IL group,while IL-βand IL-6 decreased compared with the PHN group(P<0.05).[Conclusions]Huanglian detoxification soup may raise IL-2 levels after VZV infection to promote the differentiation of cells of the immune system,so as to relieve the pain caused by IL-βand IL-6 inflammatory factors.

Occurrence,leaching behavior,and detoxification of heavy metal Cr in coal gasification slag

Coal gasification slag(CGS)is a type of solid waste produced during coal gasification,in which heavy metals severely restrict its resource utilization.In this work,the mineral occurrence and distribution of typical heavy metal Cr in CGS is investigated.The leaching behavior of Cr under different conditions is studied in detail.Acid leaching-selective oxidation-coprecipitation method is proposed based on the characteristics of Cr in CGS.The detoxification of Cr in CGS is realized,and the detoxification mechanism is clarified.Results show that Cr is highly enriched in CGS.The speciation of Cr is mainly residual fraction(74.47%-86.12%),which is combined with amorphous aluminosilicate.Cr^(3+)and Cr^(6+)account for 90.93%-94.82%and 5.18%-9.07%of total Cr,respectively.High acid concentration and high liquid-solid ratio are beneficial to destroy the lattice structure of amorphous aluminosilicate,thus improving the leaching efficiency of Cr,which can reach 97.93%under the optimal conditions.Acid leaching-selective oxidation-coprecipitation method can realize the detoxification of Cr in CGS.Under the optimal conditions,the removal rates of Fe^(3+)and Cr^(3+)in the leaching solution are 80.99%-84.79%and 70.58%-71.69%,respectively,while the loss rate of Al^(3+)is only 1.10%-3.35%.Detoxification slag exists in the form of Fe-Cr coprecipitation(Fe_(1-x)Cr_xOOH),which can be used for smelting.The detoxification acid leaching solution can be used to prepare inorganic polymer composite coagulant poly-aluminum chloride(PAC).This study can provide theoretical and data guidance for detoxification of heavy metal Cr in CGS and achieve resource utilization of coal gasification solid waste.

Isoform-and cell-state-specific APOE homeostasis and function

Apolipoprotein E is the major lipid transporter in the brain and an important player in neuron-astrocyte metabolic coupling.It ensures the survival of neurons under stressful conditions and hyperactivity by nourishing and detoxifying them.Apolipoprotein E polymorphism,combined with environmental stresses and/or age-related alterations,influences the risk of developing late-onset Alzheimer’s disease.In this review,we discuss our current knowledge of how apolipoprotein E homeostasis,i.e.its synthesis,secretion,degradation,and lipidation,is affected in Alzheimer’s disease.

Heme in intestinal epithelial cell turnover, differentiation, detoxification, inflammation, carcinogenesis, absorption and motility

The gastrointestinal tract is lined by a simple epithelium that undergoes constant renewal involving cell division, differentiation and cell death. In addition, the epithelial lining separates the hostile processes of digestion and absorption that occur in the intestinal lumen from the aseptic environment of the internal milieu by defensive mechanisms that protect the epithelium from being breached. Central to these defensive processes is the synthesis of heme and its catabolism by heme oxygenase （HO）. Dietary heme is also an important source of iron for the body which is taken up intact by the enterocyte. This review describes the recent literature on the diverse properties of heme/HO in the intestine tract. The roles of heme/HO in the regulation of the cell cycle/ apoptosis, detoxification of xenobiotics, oxidative stress, inflammation, development of colon cancer, hemeiron absorption and intestinal motility are specifically examined.

Chromium detoxification mechanism induced growth and antioxidant responses in vetiver(Chrysopogon zizanioides(L.) Roberty)

This study investigated the chromium(Cr)detoxification mechanism-induced changes in growth and antioxidant defence enzyme activities in Chrysopogon zizanioides.Plant growth decreased by 36.8%and 45.0%in the shoots and roots,respectively,in the 50 mg/L Cr treatment.Cr accumulation was higher in root(9807μg/g DW)than in shoots(8730μg/g DW).Photosynthetic pigments and malondialdehyde content increased up to the 30 mg/L Cr treatment,whereas they declined at higher doses.The activity of superoxide dismutase(SOD),catalase(CAT)and peroxidase(POX)were increased significantly with increasing of Cr dose but slightly declined at higher doses.Isozyme banding patterns revealed the expression of multiple bands for SOD,CAT and POX enzymes,and the band intensity decreased at high doses of Cr exposure.These results indicate that higher Cr doses increased the oxidative stress by over production of reactive oxygen species(ROS)in vetiver that had potential tolerance mechanism to Cr as evidenced by enhanced level of antioxidative enzymes,photosynthetic pigments,MDA contents.Therefore,vetiver has evolved a mechanism for detoxification and accumulates higher concentration of toxic Cr.This study provides a better understanding of how vetiver detoxifies Cr.

Discovery of Key Molecular Pathways of C1 Metabolism and Formaldehyde Detoxification in Maize through a Systematic Bioinformatics Literature Review

Computational systems biology approaches provide insights to understand complex molecular phenomena in living systems. Such understanding demands the need to systematically interrogate and review existing literature to refine and distil key molecular pathways. This paper explores a methodological process to identify key molecular pathways from systematic bioinformatics literature review. This process is used to identify molecular pathways for a ubiquitous molecular process in all plant biological systems: C1 metabolism and formaldehyde detoxification, specific to maize. The C1 metabolism is essential for all organisms to provide one-carbon units for methylation and other types of modifications, as well as for nucleic acid, amino acid, and other biomolecule syntheses. Formaldehyde is a toxic one-carbon molecule which is produced endogenously and found in the environment, and whose detoxification is an important part of C1 metabolism. This systematic review involves a five-part process: 1) framing of the research question;2) literature collection based on a parallel search strategy;3) relevant study selection based on search refinement;4) molecular pathway identification;and 5) integration of key molecular pathway mechanisms to yield a well-defined set molecular systems associated with a particular biochemical function. Findings from this systematic review produced three main molecular systems: a) methionine biosynthesis;b) the methylation cycle;and c) formaldehyde detoxification. Specific insights from the resulting molecular pathways indicate that normal C1 metabolism involves the transfer of a carbon group from serine through a folate-mediated pathway to methionine, and eventually the methylation of a biomolecule. In photosynthetic tissues, C1 metabolism often proceeds in reverse towards serine biosynthesis and formate oxidation. C1 metabolism, in maize, appears to be present in the developing embryo and endosperm indicating that these cells are vulnerable to perturbations in formaldehyde detoxification. These insights demonstrate the value of a systematic bioinformatics literature review process from a broad spectrum of domain literature to specific and relevant molecular pathways.

Practical Research on Physical Rehabilitation Training among Male Addicts in Chinese Compulsory Isolated Detoxification Center

Background: Physical rehabilitation training as an effective measure was proposed by relevant government sector recently. Many compulsory isolated detoxification centers had already implemented the measure, but rarely a systematically comprehensive research was published. Therefore, the purpose of this paper was to evaluate the effect of “5433” training program as an exercise intervention on addicts during drug treatment and rehabilitation, in order to provide the experimental data for the research about the effects of mental quality and physical quality of addicts. Methods: The 2132 male addicts were randomly divided into experimental group (n = 1020) and control group (n = 1112), experimental group was training by “5433” program, and control group ordinary was managed alone. Before and after one year training, in accordance with the “SCL-90” and “Standards of People’s Republic of China national physique”, the SCL-90 scores, height/weight, vital capacity, step index, grip strength, vertical jump, push-ups, sit-and-reach, one-leg standing with eye-closed, choice reaction index of two groups were detected. Results: 1) The scores of depression, anxiety, paranoia and psychosis in two groups before the experiment are both lower than those after the experiment, and the experimental group decreased more (P 0.05). Conclusion:These initial findings show that The “5433” Training Program was effective more than a simple kinesiotherapy, thereby opening avenues for the rehabilitation of Chinese drug addicts.

Effect of jasmonate treatments on leaves of Rosa rugosa‘Plena’and detoxification enzymes and feeding of adult Monolepta hieroglyphica

To study the effect of jasmonates(JAs)on the resistance of economic forest plants to insects,R osa rugosa‘Plena'leaves were treated with 1 mmol/L jasmonic acid(JA),methyl jasmonate(MeJA)and Z-jasmone,then the content of tannin and total phenol in leaves and the feeding area of Monolepta hieroglyphica adults on leaves were measured.Changes in the activities of detoxification enzymes in adult M.hieroglyphica that had fed on leaves treated with JAs were also studied.Tannin and total phenol levels in leaves increased significantly after treatment with JAs,and tannin level was 1.36–1.55-fold higher than in the control after treatment with 1 mmol/L MeJA.The total content of phenol in leaves treated with 1.0 mmol/L Z-jasmone increased by 1.33–2.20-fold compared with those of the control.The activities of detoxification enzymes in adults were inhibited to differing degrees:activity of alkaline phosphatase(AKP)first increased,then decreased;the activities of acid phosphatase(ACP),glutathione S-transferases(GSTs)and carboxylesterase(CarE)following treatment with 1 mmol/L MeJA were significantly reduced and were 22%–31%,11%–26%,and 11%–31%lower than those of the control,respectively.Moreover,the feeding area of adult M.hieroglyphica on the leaves treated with JAs was significantly reduced(P<0.05).The feeding area of economic forest R.rugosa‘Plena'leaves treated with 1 mmol/L MeJA decreased by 17%–43%compared with that of the control.Moreover,the decrease in the adult M.hieroglyphica feeding area was highly positively correlated with the content of tannin and positively correlated with the contents of total phenol of economic forest R.rugosa‘Plena'leaves.The reduced feeding area of adult M.hieroglyphica was highly negatively correlated with the activities of AKP and ACP and negatively correlated with those of the GSTs.In conclusion,the use of 1 mmol/L MeJA can noticeably decrease the deleterious effects of adult M.hieroglyphica.

Polyphenolic extract of Sorghum bicolor grains enhances reactive oxygen species detoxification in N-nitrosodiethylamine-treated rats

Reactive oxygen species detoxification potentials of Sorghum bicolor polyphenolic extract was investigated in the liver of N-nitrosodiethylaminetreated rats.Male rats,weighing(135±5.5)g were completely randomized into 7 groups(A–G)of five rats each.Rats in C,D,E and F were administered orally once daily at 24-h interval for 7 d with 500,125,250 and 500 mg/kg body weight of polyphenolic extract of S.bicolor,respectively.Group G was given 100 mg/kg body weight of vitamin C.On the sixth day,groups B,D,E,F and G were administered with 100 mg/kg body weight N-nitrosodiethylamine(NDEA).Group A,which served as the control was treated like the test groups except,that the animals received distilled water only.Reactive oxygen species detoxifying enzymes(superoxide dismutase,catalase,glutathione peroxidase,glutathione reductase and glucose 6-phosphate dehydrogenase)activities were significantly(P<0.05)induced by S.bicolor.These inductions significantly(P<0.05)attenuated the NDEA-mediated decrease in reactive oxygen species detoxifying enzymes and compared favourably with vitamin C.NDEA-mediated elevation in the concentrations of oxidative stress biomarkers;malondialdehyde,conjugated dienes,lipid hydroperoxides,protein carbonyl and percentage DNA fragmentation were significantly(P<0.05)lowered by S.bicolor polyphenolic extract.Overall,the results obtained from this study revealed that the polyphenolic extract of S.bicolor grains enhanced the detoxification of reactive oxygen species in NDEA-treated rats.The polyphenols also prevented the peroxidation of lipid,oxidation of proteins as well as fragmentation of DNA component in the liver of rats and hence gave the evidence of possible prophylactic potentials of S.bicolor grains.©2013 Beijing Academy of Food Sciences.Production and hosting by Elsevier B.V.All rights reserved.

After both treatments, the PEs （phorbol esters） was decreased by 100%. The crude protein in detoxified meal of alkali in methanol washing was less amount than only ethanol washing. The result showed that treatment by only ethanol washing was a promising way to detoxify deoiled Jatropha curcas meal for animal feeds in industrial scale.

Experimental bio-artificial liver:Importance of the architectural design on ammonia detoxification performance

AIM To determine the influence of the construction design over the biological component's performance in an experimental bio-artificial liver(BAL) device.METHODS Two BAL models for liver microorgans(LMOs) were constructed. First, we constructed a cylindrical BAL and tested it without the biological component to establish its correct functioning. Samples of blood and biological compartment(BC) fluid were taken after 0, 60, and 120 min of perfusion. Osmolality, hematocrit, ammonia and glucose concentrations, lactate dehydrogenase(LDH) release(as a LMO viability parameter), and oxygen consumption and ammonia metabolizing capacity(as LMO functionality parameters) were determined. CPSI and OTC gene expression and function were measured. The second BAL, a "flat bottom" model, was constructed using a 25 cm2 culture flask while maintaining all other components between the models. The BC of both BALs had the same capacity(approximately 50 cm3) and both were manipulated with the same perfusion system. The performances of the two BALs were compared to show the influence of architecture.RESULTS The cylindrical BAL showed a good exchange of fluids and metabolites between blood and the BC, reflected by the matching of osmolalities, and glucose and ammonia concentration ratios after 120 min of perfusion. No hemoconcentration was detected, the hematocrit levels remained stable during the whole study, and the minimal percentage of hemolysis(0.65% ± 0.10%) observed was due to the action of the peristaltic pump. When LMOs were used as biological component of this BAL they showed similar values to the ones obtained in a Normothermic Reoxygenation System(NRS) for almost all the parameters assayed. After 120 min, the results obtained were: LDH release(%): 14.7 ± 3.1 in the BAL and 15.5 ± 3.2 in the NRS(n = 6); oxygen consumption(μmol/min?g wet tissue): 1.16 ± 0.21 in the BAL and 0.84 ± 0.15 in the NRS(n = 6); relative expression of Cps1 and Otc: 0.63 ± 0.12 and 0.67 ± 0.20, respectively, in the BAL, and 0.86 ± 0.10 and 0.82 ± 0.07, respectively, in the NRS(n = 3); enzymatic activity of CPSI and OTC(U/g wet tissue): 3.03 ± 0.86 and 222.0 ± 23.5, respectively, in the BAL, and 3.12 ± 0.73 and 228.8 ± 32.8, respectively, in the NRS(n = 3). In spite of these similarities, LMOs as a biological component of the cylindrical BAL were not able to detoxify ammonia at a significant level(not detected vs 35.1% ± 7.0% of the initial 1 mM NH4+ dose in NRS, n = 6). Therefore, we built a second BAL with an entirely different design that offers a flat base BC. When LMOs were placed in this "flat bottom"device they were able to detoxify 49.3% ± 8.8% of the initial ammonia overload after 120 min of perfusion(n = 6), with a detoxification capacity of 13.2 ± 2.2 μmol/g wet tissue.CONCLUSION In this work, we demonstrate the importance of adapting the BAL architecture to the biological component characteristics to obtain an adequate BAL performance.

Effects of Nicotine, a Plant Secondary Metabolite, on Protective Enzyme and Detoxification Enzyme of Frankliniella occidentalis

[Objective] The paper was to explore the effects of plant secondary metabolite on protective enzymes and detoxification enzymes of quarantine pest Frankliniella occidentalis. [Method] F. occidentalis were continuously exposed to artificial diets containing nicotine from the second to fifth instars for five generations, and the effects of nicotine on protective enzymes and detoxification enzymes of larvae were determined. [Result]The activities of carboxylate esterase(CarE) and glutathione-S-transferase(GST) in midgut of the fifth instar larvae were significantly increased, and reached the maximum at the third generation(1.86 times and 1.59 times, respectively). Nicotine inhibited the activities of superoxide dismutase(SOD) and catalase(CAT). With the increase of feeding generations, the inhibitory effect of nicotine weakened. Nicotine significantly increased the activities of peroxidase(POD). [Conclusion] F. occidentalis will gradually adapt to the harm of plant toxins by starting its own detoxification enzyme system and regulating protective enzyme system after feeding on plant secondary substance nicotine.

Resistance Selection Against Abamectin in Tetranychus cinnabarinus(Boisduval) and Changes in Its Detoxification Enzyme Activity

The susceptible strain of Tetranychus cinnabarinus (Boisduval) was collected from the cassava germplasm resource garden of Guangxi South Subtropical Agricultural Science Research Institute and raised for 15 generations,during which resistance selection against avermectin was performed through the indoor spraying of avermectin,thereby obtaining an avermectin-resistance strain (Ab-R) with a resistance ratio of 3.25.After the indoor resistance selection,the determination of detoxification enzyme activity in the Ab-R and SS strains showed that the specific activity of carboxylesterases (CarE),glutathione-s-transferases (GSTs) and multi-functional oxidase (MFO) in Ab-R15 was 1.27,1.69 and 1.92 times of that in SS,respectively.In addition,the specific activity of MFO in Ab-R5,Ab-R10 and Ab-R15 was significantly different from that in SS;there was no significant difference in the specific activity of CarE compared with SS when screened to the F10 generation;and when screened to the F5 generation,there was no significant difference in the specific activity of GSTs compared with SS.The results showed that the significant increase in MFO activity was an important cause of resistance to avermectin in T.cinnabarinus,and CarE and GSTs were also involved in the formation of avermectin-resistant strains.

Objective:To evaluate the effect of heat-clearing and detoxifying method on the macrophages polarization in patients with acute myocardial infarction with heat toxin syndrome after intervention.Methods:Sixty patients with acute myocardial infarction and undergoing percutaneous coronary intervention with heat toxin syndrome were randomly divided into a control group and a test group with 30 cases each.The control group was given conventional treatment,and the test group was given Huanglian Jiedu Decoction,the representative of the method of clearing heat and detoxification,orally on the basis of the control group.The intervention time of both groups was 2 weeks.Comparing The Seattle Angina Pectoris Scale(SAQ)before and after treatment,creatine kinase(CK),creatine kinase MB isoenzyme(CKMB),high-sensitivity troponin I(hs-TnI),and Lipoprotein-associated phospholipaseA2(LPPLA_2)),the phenotype ratio of M1 and M2 macrophages,and observe the adverse reactions.Results:After treatment,the SAQ scores of the two groups of patients were improved,and the levels of CK,CK-MB,hs-TnI,and LP-PLA_2 decreased significantly.The scores of AS,AF,TS,and DP in the SAQ of the test group were all higher than those of the control group,and the hs-TnI and LP-PLA_2 were better than those of the control Group(P<0.05 or P<0.01).After treatment,the proportion of M1 type macrophages in the two groups of patients'macrophages decreased significantly(P<0.05 or P<0.01),the ratio of M2 type macrophages increased(P<0.05),and the M1/M2 ratio decreased.The ratio of M1/M2 in the test group of the control group was significantly lower than that of the control group(P<0.01).There were no obvious adverse reactions in both groups.Conclusions:The method of clearing heat and detoxifying has a definite effect on patients with acute myocardial infarction of heat toxin syndrome after interventional operation.It can reduce myocardial damage,improve myocardial function,and reduce inflammation.And it is safe for clinical treatment without any increasing risk of bleeding or other risk of cardiovascular events.

Effects of Cadmium on the Energy Substances and Immune Detoxification Enzyme System of Infected Pirata subpiraticus

In order to investigate the effects of cadmium on the immune defense function of spiders infected with bacteria,Pirata subpiraticus was taken as research object,and the cadmium-treated group and the control group were all infected with bacteria(S.aureus and E.coli).After 6 and 24 h of infection,the energy substances contents and the activity of immune detoxification enzyme system in Pirata subpiraticus were determined.The results showed that after 6 and 24 h of infection with S.aureus and 6 h of infection with E.coli,the amount of soluble sugars and soluble proteins of Pirata subpiraticus in the cadmium-treated group increased significantly.Compared with the control,after 6 h of infection with S.aureus and 24 h of infection with E.coli,the activity of acetylcholinesterase(AChE)of Pirata subpiraticus in the cadmium-treated group decreased significantly.This indicated that cadmium inhibited the activity of AChE in infected Pirata subpiraticus.After 24 h of infection with S.aureus and 6 h of infection with E.coli,the activity of polyphenol oxidase(PPO)was signicantly higher than that of the control,indicating that cadmium induced the activity of PPO in infected Pirata subpiraticus.These results suggested that cadmium can affect the content of energy substance and immune detoxification enzyme activity in infected Pirata subpiraticus.

Degradation and Detoxification of Persistent Organic Pollutants in Soils by Plant Alkaloid Anabasine

The development of a technology employing materials containing specific alkaloids from biomasses of agricultural production would be extremely beneficial and relatively inexpensive for the remediation of polluted soils and may represent a possible new industrial and commercial opportunity. We have studied detoxification and degradation of persistent chloroorganic pesticides by using plant extracts, which contained alkaloids. Reactions DDT with alkaloid Anabasine and extractive sum of alkaloids, isolated from ground up part plant Anabasis аphylla proceed more easy without solvent. It is established, that at interaction alkaloids of Anabasis aphylla with pesticide DDT occurs degradation to formation of less toxic DDE. Results the carried out researches on studying interaction sum of alkaloids, isolated from ground up part plant Anabasis Ahylla, with DDT in various ratio (1:1, 2:1, 3:1) have shown, that thus there are detoxification pesticide DDT on 35% - 45%, 75% - 80% and 80% - 85% according to formation dichlorodiphenyldichloroethylene (DDE), and in presence humic acids the degree degradation achieves to 95% - 97%.
