Lethal Effect of Benzene Nitrogen Mustard Glucoside Derivate on K562 Cells

A new synthesized benzene nitrogen mustard was converted into glycosyl donor-trichloroacetimidate that was glycosylated with p-nitrophenol（glycosyl donors） to form β-lactosyl p-nitrobenzene under the protection of acetyl in a stereoselective manner, was prepared and evaluated for its cytotoxicity towards cultured K562 cell line. Methylthiazoy tetrazolium（MTT） assay, transmission electron microscopy（TEM）, flow cytometry（FCM） and immunohistochemistry were utilized to explore the mechanisms of how the compound arrests the growth of HCT-T cells. This new synthesed benzene nitrogen mustard glucoside derivate（BNMGD） presented a lower toxicity to normal cells, but is significantly more toxic to K562 cells compared with nitrogen mustard, meanwhile it can induce the apoptosis of K562 cells. These results indicate that the new synthesized BNMGD can inhibit the growth of K562 cells and induce the apoptosis, and its cytotoxicity towards cultured K562 cell line is much more effective than that of nitrogen mustard.

Effect of Pest Exclusion Net(PEN)on the Sustainable Production of Late Season Broad Leaf Mustard(BLM)in Chitwan,Nepal

Broad leaf mustard(BLM)(Brassica juncea L.var.rugosa,Brassicaceae)is one of the most widely consumed vegetable crops in Nepal.The production of crop in open field is constrained by major pests like mustard aphid and flea beetle.This study was aimed to determine the effects of pest exclusion net(PEN)on pest-infestation and yield of BLM cultivar“Khumal Broad Leaf”.The experiment was carried out in randomized complete block design(RCBD)with five treatments and four replications.The treatments included control(no mulch+no net+no pesticide spray),black plastic mulch only,reflective plastic mulch only,black plastic mulch+no net+pesticide spray,and PEN+black plastic mulch+no pesticide spray.Data were analyzed with RSTAT software package and means were separated by Duncan’s multiple range test(DMRT)at 5%level of significance.The result revealed that crop under PEN had highest plant height(38.99 cm),lowest number of aphid(0-0.86 per plant),flea beetle(0-1.07 per plant)and highest total marketable yield(77.50 ton/ha)while control had lowest plant height(20.06 cm),highest number of aphid(maximum 2.49 per plant),flea beetle(maximum 2.00 per plant)and lowest total marketable yield(13.75 ton/ha).Economic analysis revealed highest benefit-cost ratio in PEN(9.90).This study indicates that the use of PEN protect BLM against aphid and flea beetle,increases yield and can be considered as a viable technology for BLM production by smallholder growers of Nepal.

Design and Synthesis of Glycosylated Aromatic Nitrogen Mustard Derivatives

Antibody-directed enzyme prodrug therapy（ADEPT） is a new strategy for the treatment of cancer that has arisen in recent twenty years, the main merits of which are that it can improve the selectivity of anticancer drugs and reduce the side effects in remote tissue. In the present study, two prodrugs-glycosylated aromatic nitrogen mustard derivatives were synthesized. Glucose and lactose were converted into glycosyl donors-trichloroacetimidate; the obtained glycosyl donors were glycosylated with p-nitrophenol （ glycosyl donors） to form β-glucosyl p-nitrobenzene and β-lactosyl p-nitrobenzene that were protected by acetyl in a stereoselective manner; the two products were reduced by zinc dust and then treated with ethylene oxide, afforded two glycosylated nitrogen mustard derivatives that were protected by acetyl; the last step was to deacetylate and then afforded the two target compounds that could be used as prodrugs of ADEPT for further Anti-tumor research.

Prophylactic Effect of Gossypin Against Percutaneously Administered Sulfur Mustard

Objective To evaluate the protective efficacy of gossypin （3,3＇,4＇,5,7,8-hexahydroxyflavone 8-glucoside） by administering it intraperitoneally, for dose, time, and vehicle dependent effects against sulphur mustard （SM）, administered through percutaneous route in mice. Methods SM （diluted in PEG-300） was administered percutaneously. The protective efficacy of gossypin was evaluated by administering it intraperitoneally （50, 100, 200, and 400 mg/kg）, in various vehicles （water, PEG-300 and DMSO）, and time intervals （30 min prior, simultaneous and 2 h post）. The time dependent protection of gossypin （200 mg/kg in PEG-300; i.p.） was also evaluated using selected biochemical variables （GSH, GSSG, MDA, total antioxidant status, Hb, WBC count, RBC count, glutathione peroxidase, glutathione reductase, and superoxide dismutase） and liver histology. The protection of gossypin by oral route was also evaluated against percutaneously administered SM. Results The protection against systemic toxicity of SM （LD50 8.1 mg/kg） was better when gossypin was given with PEG-300 （8.0 folds） than DMSO （5.7 folds）. No protection was observed when gossypin was administered with water. Good protection （8.0 folds） was observed when gossypin was administered （200 mg/kg in PEG-300; i.p.） at 30 min prior or simultaneous to SM exposure, but no protection was observed when gossypin was administered 2 h post to SM exposure. A significant weight loss was observed 7 days after SM administration （2 LD50）, with a significant increase in RBC and Hb. A significant decrease in total antioxidant status of plasma, liver GSH and GSSG levels, and in the activities of glutathione peroxidase, glutathione reductase and superoxide dismutase was also observed 7 days after SM administration. SM treated mouse liver also showed necrosis. A significant protection was observed when gossypin （200 mg/kg in PEG-300; i.p.） was administered either as a pretreatment （30 min before） or simultaneous treatment, and not as a post treatment （2 h）. The protective efficacy of gossypin was better through oral route when administered with DMSO （4.8 folds） than with PEG-300 （2.4 folds）. No protection was observed when gossypin was administered orally with water. Conclusion Percutaneous administration of SM induces oxidative stress and gossypin can protect it as a prophylactic agent by intraperitoneal or oral routes.

Sulphur Mustard Induced Oxidative Stress and Its Prevention by Sodium 2, 3-Dimercapto Propane Sulphonic Acid (DMPS) in Mice

Sulphur mustard [bis(2 chloro ethyl) sulfide] (SM), a bifunctional alkylating agent has been frequently used as a chemical warfare agent. In the present study, the effects of sodium 2 3 dimercaptopropane sulphonic acid (DMPS) on some biochemical and histological parameters in mice, exposed to 1/4LC 50 concentration of SM vapor (10.5 mg/m\+3) were examined over a period of seven days. Exposure of SM resulted in a significant loss of blood, hepatic and pulmonary glutathione (GSH) and an elevation of hepatic and pulmonary oxidized glutathione (GSSG). These biochemical changes were accompanied by a number of histopathological alterations. The most prominent was congestion and degeneration in viscera and obliteration of chromatin material. These biochemical and histopathological changes were less marked in animals pre administered with DMPS followed by DMPS exposure indicating some protective value of the thiol (DMPS) against SM induced oxidative injury in mice.

Histomorphological and Histochemical Alterations Following Short-term Inhalation Exposure to Sulfur Mustard on Visceral Organs of Mice

Toxic effects of inhaled sulfur mustard (SM) on the histology of visceral organs was investigaed by exposing mice to 84. 6mg/m3 for 1h duration, using controlled single exposure conditions. A progressive fall in body weight from third day onwards was noticed. Light microscopic examination of the pulmonary tissue of these animals at 6 h post exposure revealed that the tracheobronchial epithelium remained intact, but was infiltrated by inflammatory cells. By 24 h post exposure, the mucosecretory cells were destroyed. The indanunatory reaction was maximum at 48 h. By 7th day post exposure there was swelling and vacuolation of lung parenchymal cells and thrombi formation. In addition SM caused congestion and hemorrhage at alveolar level. SM also caused granulovacuolar degeneration with perinuclear clumping of the cytopasm of hepatocytes and renal parenchymal cells. Renallesions were chazacterized by congestion and hemorrhage. Among visceral tissues, maximum atrophywas observed in spleen. Distribution of lesions increased with post exposure period. The maximum lesions were observed at 7th day post-exposure.

Distribution of cadmium in oilseed rape and Indian mustard grown on cadmium contaminated soil

Heavy metal distribution in the specialized accumulating plants was important for phytoextraction technique. Hydroponic and pot experiment were conducted to investigated Cd phytoextraction ability and Cd distribution in the plant of oilseed rape species. The results showed that oilseed rape Chuanyou Ⅱ-10 was more effective in phytoexetraction Cd among 21 varieties of oilseed rape and indicator plant Indian mustard. Cd concentration in the shoot of Chuanyou Ⅱ-10 and Indian mustard gradually decreased with an increase in growth period, while the amount of Cd uptake increased with the increase of growth period. There was constantly decrease in Cd concentration from the base leaves to the top leaves of Chuanyou Ⅱ-10 and Indian mustard, the percentages of Cd uptake in older leaves were higher than those of younger leaves. Older leaves of Chuanyou Ⅱ-10 and Indian mustard extracted more Cd for the Cd contamination soil, leaves should as far as possible develop before they reached the soil and the older leaves were harvested in priority.

The injury progression of T lymphocytes in a mouse model with subcutaneous injection of a high dose of sulfur mustard

Background: In clinical studies, the findings on sulfur mustard(SM) toxicity for CD3+CD4+ and CD3+CD8+ T lymphocyte subsets are contradictory. In animal experiments, the effect of SM on the T cell number and proliferation is incompatible and is even the opposite of the results in human studies. In this study, we observed the dynamic changes of T lymphocytes in the first week in a high-dose SM-induced model.Methods: Mice were exposed to SM by subcutaneous injection(20 mg/kg) and were sacrificed 4 h, 24 h, 72 h and 168 h later. Spleen T lymphocyte proliferation was evaluated by 3H-Td R. Flow cytometric analysis was used to observe the percentage of CD3+CD4+ and CD3+CD8+ T lymphocyte subsets. The IL-1e assayed using the Luminex method. DNA damage in bone marrow ceβ, IL-6, IL-10 and TNF-lls was observed with α levels in plasma werthe single cell gel electrophoresis technique(SCGE).Results: SM continuously inhibited the proliferation of lymphocytes for 7 days, and there was a significant rebound of Con A-induced T lymphocyte proliferation only at 24 h. The percentage of CD3+CD4+ and CD3+CD8+ lymphocytes was upregulated, which was accompanied by increased IL-1β and TNF-creased in the PG group at 4 h. The peak of lymphocytic apoptα and decreased IL-10. The IL-6 level was gradually deosis and DNA damage occurred at 24 h and 72 h, respectively. Conclusion: Our results show that SM significantly inhibited T lymphocyte proliferation as well as induced CD3+CD4+ and CD3+CD8+ upregulation. SM intoxication also significantly increased the levels of pro-inflammatory cytokines(IL-1β, IL-6 and TNF-α) and inhibited the level of anti-inflammatory cytokine IL-10. Our results may partly be due to the significant SM induced significant apoptosis and necrosis of lymphocytes as well as DNA damage of bone marrow cells. The results provided a favorable evaluation of SM immune toxicity in an animal model.

Cloning and Sequencing Characteristics of rDNA ITS Region of the Pathogen Causing Black Spot Disease on Tumorous Stem Mustard

Taking tumorous stem mustard infected by black spot disease as the research material, the ribosomal 5.8S rDNA and its flanking ITS region were cloned, sequenced and aligned in the study. The results showed that the base sequence of pathogens collected from five different sites was almost identical with that of Alternaria brassicae, and the similarity degree reached 99.68%, without base difference greater than 3 bp. It had obvious differences with the sequences of A. brassicicola and A. japonica, and the base difference was greater than 3 bp with a lot of fragment deletions. It was preliminarily determined that the pathogen cau- sing black spot disease on tumorous stem mustard was A. brassicae.

<i>In vitro</i>Bile Acid Binding of Mustard Greens, Kale, Broccoli, Cabbage and Green Bell Pepper Improves with Sautéing Compared with Raw or Other Methods of Preparation

Bile acid binding potential of foods and food fractions has been related to lowering the risk of heart disease and that of cancer. Steam cooking has been observed to significantly improve bile acid binding of green/leafy vegetables. It was hypothesized that other cooking methods could further improve the bile acid binding of various vegetables. Sautée cooking resulted in in vitro bile acid binding measured on a dry matter basis relative to cholestyramine of 14% for mustard greens and kale, 9% for broccoli, 8% for collard greens, 6% for cabbage, and 5% for green bell pepper. These results point to the significantly different (P ≤ 0.05) health promoting potential of mustard greens = kale > broccoli > collard greens > cabbage > green bell pepper. Sautéing significantly improved in vitro bile acid binding of mustard greens, kale, broccoli, cabbage and green bell pepper compared with steaming, boiling or raw (uncooked). Collard greens exhibited significantly higher bile acid binding by steaming compared with sautéing, boiling or raw. Data suggest that the cooking method with most heath promoting potential for mustard greens, kale, broccoli, cabbage and green bell pepper should be sautéing. Steaming should be used for collard greens as the cooking method. These green/leafy vegetables, when consumed regularly after sautéing, would promote a healthy lifestyle and have the potential to lower the risk of premature degenerative diseases.

Evaluation of CC2 as a Decontaminant in Various Hydrophilicand Lipophilic Formulations Against Sulphur Mustard

Objective To evaluate CC2 (N, N’-dichloro-bis [2, 4, 6-trichlorophenyl] urea) invarious hydrophilic and lipophilic formulations as a personnel decontaminant for sulphurmustard (SM). Methods Twenty percent of CC2 was prepared as a suspension or ointmentwith various chemical agents and its stability was evaluated by active chlorine assay. Theefficacy was evaluated in mice by recording the mortality after applying 29 LD50 of SM (LD50 =8.1 mg/kg dermally) and decontaminating it after 2 min with 200 mg of the formulation.Studies were also carried out with 10% and 20% CC2 in acacia and hydroxypropyl cellulose,and the suspensions were stored in polyethylene containers. The stability of the suspensionswas evaluated by active chlorine assay. The efficacy was evaluated by recording themortality after applying 29 LD50 of SM in mice and 12 LD50 of SM in rats (LD50 = 2.4 mg/kgdermally), and decontaminating it with the formulations. LD50 by different routes andprimary skin irritation test of CC2 were also carried out. Results CC2 reacted with peanutoil and neem oil, and was unstable in povidone iodine and Fuller’s earth. Good stability wasachieved with petroleum jelly, honey, polyvinyl pyrrolidone, calamine lotion, acacia andhydroxypropyl cellulose. Though CC2 was stable in lipophilic formulations, it did notprotect the animals. The hydrophilic formulations particularly acacia and hydroxypropylcellulose gave very good protection and was stable in the polyethylene containers for aperiod of 1 year. The efficacy of 20% CC2 was better than 10% CC2. The oral and dermalLD50 of CC2 was found to be above 5.0 g/kg. CC2 was also found to be nonirritant.Conclusion Twenty percent of CC2 in hydroxypropyl cellulose is better with respect tostability, efficacy and ease of decontamination. CC2 is also a safe chemical.

The Effects of Mustard Protein Concentrate on Nutrient Digestibility and Performance of Broiler Chickens

This experiment was conducted to de- termine the effects of feeding mustard protein concen- trate on nutrient digestibility and the performance of broiler chickens. A total of 180, day-old, male broiler chickens, weighing an average of 52.8±0.6 g, were randomly assigned to one of six dietary treatments in a randomized block design. The control diet was based on wheat and soybean meal and contained 15% cano- la meal. The experimental diets contained 3 %, 6%, 9% ,12% or 15% mustard protein concentrate added at the expense of canola meal. The digestibility of crude protein and energy declined linearly （ P 〈 0.01 ） with increasing levels of mustard protein concentrate. In addition, weight gain and feed intake were linearly （P 〈 0.01 ） reduced as the level of mustard protein concentrate in the diet increased. Feed conversion wasalso negatively affected （ P 〈 O. O1 ） by mustard pro- tein concentrate while mortality did not differ among treatments. The results of the present experiment pro- vide a strong indication that there is a factor or factors present in mustard protein concentrate which negative- ly affects broiler performance. The process through which the protein in mustard seed is concentrated from mustard meal may concentrate some of the anti-nutri- tional factors found in mustard. Previous research has reported an increase in the concentration of phenolic compounds in protein isolates from mustard and this may be the cause of the reduction in performance as the level of mustard protein concentrate in the diet in- creased. Further research should be conducted to test this hypothesis.

Analysis of the Relationship between Soil pH and Clubroo of Mustard

[Objective]The paper was to study the severity of mustard clubtoot under different pH conditions and to clear the relationship between pH and mustard clubroot.[Method] Totally 288 soil samples were collected from the infected patches of clubroot in Fuling District,Chongqing City,and their pH were measured.Meanwhile,the germination rate of resting spores,the incidence rate of clubroot and vegetative growth of mustard was measured under different pH conditions,to figure out the relationship between pH and mustard clubroot.[Result] The pH of 288 pathogenic soil samples distributed from 4.0 to 7.0.The germination rates of resting spores were higher than 50% when the pH was 5.0-6.5,and the germination rates were low when the pH was 3.0,4.0,8.0,8.5,9.0 and 10.0.Greenhouse pot test showed that the incidence rate of mustard clubroot in acidic environment was higher than that in alkaline environment.The incidence of mustard clubroot was severe when the pH was 4.5-6.5; the incidence was the severest at the pH of 6.0,and the disease index reached 84.22; mustard was not attacked by clubroot at the pH of 8.0.Measurement results of various growth indicators of mustard under different pH conditions demonstrated that mustard had better growth at the pH of 5.0-7.5,and the growth was the best at the pH of 6.5,while the growth was suppressed at the pH of 4.0 and 8.0.[Conclusion]Clubroot of mustard is likely to happen under weak acidic condition.The suitable pH for the vegetative growth of mustard is 5.0-7.5.

Salt-Induced Changes in Physio-Biochemical and Antioxidant Defense System in Mustard Genotypes

Salinity stress is a major factor limiting plant growth and productivity of many crops including oilseed.The present study investigated the identification of salt tolerant mustard genotypes and better understanding the mechanism of salinity tolerance.Salt stresses significantly reduced relative water content(RWC),chlorophyll(Chl)content,K^(+) and K^(+)/Na^(+) ratio,photosynthetic rate(P N),tran-spiration rate(Tr),stomatal conductance(gs),intercellular CO_(2) concentration(Ci)and increased the levels of proline(Pro)and lipid peroxidation(MDA)contents,Na+,superoxide(O_(2)^(•−))and hydrogen peroxide(H_(2)O_(2))in both tolerant and sensitive mustard genotypes.The tolerant genotypes maintained higher Pro and lower MDA content than the salt sensitive genotypes under stress condition.The activities of superoxide dismutase(SOD),catalase(CAT),peroxidase(POD),glutathione peroxidase(GPX),monodehydroascorbate reductase(MDHAR)and dehydroascorbate reductase(DHAR)were increased with increasing salinity in salt tolerant genotypes,BJ-1603,BARI Sarisha-11 and BARI Sarisha-16,but the activities were unchanged in salt sensitive genotype,BARI Sarisha-14.Besides,the increment of ascorbate peroxidase(APX)activity was higher in salt sensitive genotype as compared to tolerant ones.However,the activ-ities of glutathione reductase(GR)and glutathione S-transferase(GST)were increased sharply at stress conditions in tolerant genotypes as compared to sensi-tive genotype.Higher accumulation of Pro along with improved physiological and biochemical parameters as well as reduced oxidative damage by up-regulation of antioxidant defense system are the mechanisms of salt tolerance in selected mustard genotypes,BJ-1603 and BARI Sarisha-16.

Effect of Chemical Seed Treatment and BAU-Biofungicide on <i>Alternaria</i>Blight <i>(Alternaria brassicae)</i>of Mustard

The efficacy of three seed treating chemicals viz. Provax 200 WP, Brine solution, Rovral 50 WP and one Biofungicide viz. BAU-Biofungicide were evaluated against Alternaria blight of mustard caused by Alternaria brassicae and Alternaria brassicicola. Three varieties viz. var. BARI-6, Tori-7 and SAU-Shorisha-1 were used in this study. The field experiment was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka and laboratory experiment was conducted in the seed health Laboratory, Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November 2008 to July 2009. Among the seed treating chemicals, Rovral 50WP showed the best performance in reducing disease incidence and severity as well as increasing seed yield. Application of Rovral 50 WP gave the best result in increasing the number of pod per plant, pod length (cm), number of branch per plant, 100 siliqua weight (g) and 1000 seed weight (g). BAU-Biofungicide also showed promising performance in controlling Alternaria blight of mustard and reduced 36% and 53% disease incidence and disease severity respectively over untreated control. BAU-Biofungicide may be recommended as an alternative means of chemical fungicide such as Rovral 50 WP for controlling Alternaria blight of mustard.

Evaluation of IL-6 and IL-8 in Tear Fluid of Sulfur Mustard Gas-Exposed Patients with Eye Lesions

The purpose of this study is to compare the levels of IL-6, 8 in tear fluids of people exposed to mustard gas in the war between Iraq and Iran who had the chronic dry-eye symptoms compared to the normal group. In this study, 25 of the patients who were exposed to mustard gas and had chronic dry eye symptoms were compared to 25 patients as control group, consisting of 25 people who had common chronic dry eye symptoms with blepharitis and 25 healthy people as normal group. The levels of IL-6 and IL-8 in tear fluid of people of these three groups were assessed by enzyme-linked immunosorbent assay (ELISA). The results for levels of IL-6 (P = 0.002) and IL-8 (P = 0.001) in tear fluid of patients in comparison with normal group show a significant increase. The differences were considered statistically significant at P < 0.05. The effect of exposure to mustard gas on eyes of chemical-injured veterans destroyed meibomian glands which paved the way for evaporative type of dry-eye. As a result, the cited ILs in the tear fluid of these patients increased and resulted in later eye-impairments.

44 Victimization of Sulfur Mustard in Qiqihar: Case Reports

Background: Sulfur mustard (2,2’-bis-chloroethyl-sulfide;SM) has been a military threat since the World War I. SM is the major chemical warfare agent used byJapanduring World War II. The clinical picture of poisoning, including cutaneous blisters, respiratory tract damage, ocular lesions and bone marrow depression is well known. In this report, we describe a civilian exposure in August 2003, in Qiqihar, Northeast China’s Heilongjiang Province. Aim: To describe the clinical features and treatment of sulfur mustard toxicity. Results: In 44 victims of SM exposure, 32 had ocular symptoms;43 showed significant skin blistering and pigmentation;15 had pulmonary symptoms such as productive cough occurred;18 have Central nervous symptoms and other effects. Conclusion: The 44 victims were all injured, when five barrels of mustard gas were dug up at a construction site inQiqihar. The gas leak killed one and injured 43 others, one of the worst accidents involving chemical weapons abandoned by Japanese invading troops in China after WWII.

Measuring Tumor Necrosis Factor-Alpha and Interleukin-1 Beta Levels in Mustard Gas Exposed Patients

Sulfur mustard (SM) is an alkalizing chemical which has been used mostly as a weapon all over the world. Sulfur mustard can cause damages to many organs, especially the skin, respiratory system and the eyes. Generally, many complications of mustard gas result from its alkalizing potency and reaction with cellular components like DNA, RNA, proteins and lipid membranes. The damages caused by SM will lead to many complications which persist during the lifespan of exposed subjects. Pro-inflammatory cytokines including especially TNF-α and IL-1β can cause systemic inflammatory reactions and vast changes like altered cell signaling, migration, cytokine production changes and fever. This study was designed to analyze cytokine levels in mustard-gas-exposed people’s serum in the war between Iraq and Iran, who had the chronic dry-eye symptoms compared to the normal group, 30 years after exposure. In this study, 25 veterans who were exposed to mustard gas were compared to 25 healthy people as control group. The veterans with concurrent involvement of eye, lung, and skin were selected. We used ELISA method to assess the levels of TNF-α and IL-1β in serum of people in both groups. All the results analyzed with T-test in SPSS 17 statistical software. The mean levels of TNF-α and IL-1β in serum of chemical exposed veterans were 52.3 ± 1.4 pg/ml and 3.43 ± 0.3 pg/ml while in the control group were 19.5±1.3 pg/ml and 2.25 ± 0.2 pg/ml, respectively. In the control group, the serum pro-inflammatory cytokine levels were significantly lower than the exposed group (P < 0.05). This study showed that there is a meaningful difference between TNF-α and IL-1β serum levels in the SM exposed group compared to the control group. There are some differences between the present study and others. However, studies on local inflammatory changes in these patients are also limited and need more reviews.
