Exploration of the efficacy and mechanism of treating head wind disease with the combination change of ginger volatile oil and gingerol by using content-weighted network pharmacology technology

Background:Exploring the efficacy,potential components,and mechanism of the combination of ginger essential oil and gingerols in the treatment of head wind disease based on network pharmacology technology with content weight.Methods:The experimental groups were divided into:0:10,1:4,1:2,1:1,2:1,4:1,10:0.The relative content(Ri)of the chemical constituents of ginger's volatile oil was determined using gas chromatography-mass spectrometry(GC-MS).Additionally,the physicochemical and biological property parameters(LogP,MDCK,PPB,MW)of the components were considered.To assess the quantitative effect of the components,a grading score was performed,and the quantitative effect index(Ki)was calculated.Subsequently,the target effect index(Ti)was calculated by combining the component-target matching score(Fit score).Using these calculations,the target effect score A was determined under the influence of multiple components targeting different targets.Key targets with A≥1000 were identified.To predict the targets related to head wind disease,the Comparative Toxicogenomics Database(https://ctdbase.org/),Gene Cards(https://www.genecards.org/),and Disgenet database(https://www.disgenet.org/)were utilized.The key targets,obtained from different proportions of ginger's volatile oil and gingerol,were intersected with the predicted targets.This facilitated network pharmacological analysis and verification of the efficacy.Results:The content of volatile oil in ginger demonstrated an impact on key targets associated with the volatile oil group.Each specific combination of volatile oil consistently activated distinct pathways,with variations stemming from changes in content.Experimental testing revealed that different combinations of ginger's volatile oil and gingerol effectively alleviated migraine symptoms in rats.Conclusion:Through the application of content-weighted network pharmacology technology and pharmacodynamic verification,it was determined that altering the ratio between ginger's volatile oil and gingerol leads to variations in potential targets and pathways,consequently impacting its efficacy.

Determination of Natural Logarithm of Diffusion Coefficient and Activation Energy of Thin Layer Drying Process of Ginger Rhizome Slices

This study is an extension of the previous work done with ARS-680 Environmental Chamber. Drying is a complex operation that demands much energy and time. Drying is essentially important for preservation of ginger rhizome. Drying of ginger was modeled, and then the effective diffusion coefficient and activation energy were determined. For this purpose, the experiments were done at six levels of varied temperatures: 10°C, 20°C, 30°C, 40°C, 50°C and 60°C. The values of effective diffusion coefficients obtained in this work for the variously treated ginger rhizomes closely agreed with the average effective diffusion coefficients of other notable authors who determined the drying kinetics and convective heat transfer coefficients of ginger slices.

Phytochemistry and pharmacology of ornamental gingers,Hedychium coronarium and Alpinia purpurata:a review

In this review, the phytochemistry and pharmacology of two ornamental gingers, Hedychium coronarium （butterfly ginger） and Alpinia purpurata （red ginger）, are updated, and their botany and uses are described. Flowers of H. coronarium are large, showy, white, yellow or white with a yellow centre and highly fragrant. Inflorescences of A. purpurata are erect spikes with attractive red or pink bracts. Phytochemical investigations on the rhizomes of H. coronarium generated research interest globally. This resulted in the isolation of 53 labdane-type diterpenes, with little work done on the leaves and flowers. Pharmacological properties of H. coronarium included antioxidant, antibacterial, antifungal, cytotoxic, chemopreventive, anti-allergic, larvicidal, anthelminthic, analgesic, anti-inflammatory, anti-urolithiatic, anti-angiogenic, neuro- pharmacological, fibrinogenolytic, coagulant and hepatoprotective activities. On the contrary, little is known on the phytochemistry of A. purpurata with pharmacological properties of antioxidant, antibacterial, larvicidal, cytotoxic and vasodilator activities reported in the leaves and rhizomes. There is much disparity in terms of research effort within and between these two ornamental gingers.

Ginger polysaccharide UGP1 suppressed human colon cancer growth via p53,Bax/Bcl-2,caspase-3 pathways and immunomodulation

In previous study,we got a purified ginger polysaccharide UGP1 and verified its significant antitumor activities on colon cancer HCT116 cells.In this article,we aimed to illustrate the underlying mechanism of UGP1 exerted antitumor activities on colon cancer by using in vitro cell models and in vivo animal models.The results demonstrated that UGP1 could induce S-phase cell cycle arrest,up-regulate the expression of Bax and p53,down-regulate the expression of Bcl-2,and activate the downstream protein caspase-9 and caspase-3,which was related to intrinsic apoptosis pathway on HCT116 cells.Moreover,UGP1 significantly stimulated RAW264.7 cell proliferation and secretion activity.Similarly,UGP1 inhibited tumor proliferation on tumor-bearing mice,increased the expression of p53 and the ratio of Bax/Bcl-2,enhanced the secretion of pro-inflammatory cytokines TNF-α,IL-2,IL-6 and decreased the secretion of pro-tumor cytokines TGF-βand b FGF in serum.In conclusion,it indicated that the UGP 1 could sup press human colon cancer growth by inducing apoptosis via the regulation of p53,caspase-3,and Bax/Bcl-2 ratio-dependent pathway and regulating immune system activity.Thi s investigation provided basic theoretical mechanism of ginger polysaccharideexerted antitumor activities,and contributed to develop a possible functional food or adjuvant agent for prevention or treatment of colon cancer.

Research progress of ginger in the treatment of gastrointestinal tumors

Cancer seriously endangers human health.Gastrointestinal cancer is the most common and major malignant tumor,and its morbidity and mortality are gradually increasing.Although there are effective treatments such as radio-therapy and chemotherapy for gastrointestinal tumors,they are often accom-panied by serious side effects.According to the traditional Chinese medicine and food homology theory,many materials are both food and medicine.Moreover,food is just as capable of preventing and treating diseases as medicine.Medicine and food homologous herbs not only have excellent pharmacological effects and activities but also have few side effects.As a typical medicinal herb with both medicinal and edible uses,some components of ginger have been shown to have good efficacy and safety against cancer.A mass of evidence has also shown that ginger has anti-tumor effects on digestive tract cancers(such as gastric cancer,colorectal cancer,liver cancer,laryngeal cancer,and pancreatic cancer)through a variety of pathways.The aim of this study is to investigate the mechanisms of action of the main components of ginger and their potential clinical applications in treating gastrointestinal tumors.

Growth indices of seeds(maize and cowpea)grown in heavy metal contaminated soil treated with ginger extract

The consumption of maize and cowpea in Africa and developing countries is high,owing to the fact that they are readily available,coupled the with nutritional benefits they provide.Growth loss has been seen in crops cultivated on heavy metal polluted soils as a consequence of alterations in physiological and biochemical processes.This study was aimed at assessing the growth indices of seeds(maize and cowpea)grown on heavy metal contaminated soil treated with ginger extracts.The study adopted a Complete Randomized Design(CRD)in which growth indices of either maize or cowpea were examined from each crop type grown on soil without any pollutant or treatment and soils with metal pollutants;with or without treatment with ginger extracts in the individual experiments.Data were analyzed using ANOVA.The results showed that ginger extract induced oxidative stress on cowpea after 10 days of cultivation with root length significantly(P≤0.05)higher on the normal control-G-M and+L-G which recorded 7.60 and 7.3 cm respectively.Patterns of growth indices noticed after 30 and 40 days of cowpea cultivation were variable showing least growth in leaf development.Highest maize root(27.00 cm),shoot(8.85 cm)and leaf(25.25 cm)development were recorded in maize grown on soil without metal contamination but treated with ginger(+G-M-positive control)after days 10,40 and 40 after cultivation.It was observed that the soil contaminated with heavy metals affected the growth pattern of the crops thereby causing stunted growth,chlorosis,discoloration and wilting.It could be concluded that cowpea performed better in shoot of both treated and untreated soils even though the values were not significantly different from that of root and leaf while maize showed a decrease in shoot even though the values for root and leaf were not significantly different.

Objective:To evaluate the additive action of ginger starch on the antifungal activity of honey against Candida albicans(C.albicans).Methods:C.albicans was used to determine the minimum inhibitory concentration(MIC)of four varieties of Algerian honey.Lower concentrations of honey than the MIC were incubated with a set of concentrations of starch and then added to media to detennine the minimum additive inhibitory concentration(MAIC).Results:The MIC for the four varieties of honey without starch against C.albicans ranged between 38%and 42%(v/v).When starch was incubated with honey and then added to media,a MIC drop was noticed with each variety.MAIC of the four varieties ranged between 32%honey(v/v)with 4%starch and 36%honey(v/v) with 2%starch.Conclusions:The use of ginger starch allows honey benefit and will constitute an alternative way against the resistance to antifungal agents.

Potential efficacy of ginger as a natural supplement for nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease(NAFLD) is one of the most common liver diseases and its prevalence is likely to reach epidemic proportions.According to the"two-stage hypothesis"proposed for the pathophysiology of NAFLD,insulin resistance,oxidative stress and pro-inflammatory cytokines are among the key promoters of the disease. Here,ginger has been hypothesized to prevent NAFLD or blunt its progression via several mechanisms,such as sensitizing insulin effects,activating peroxisome proliferator-activated receptorγwhich induces adiponectin and down-regulates pro-inflammatory cytokines,changing the balance between adiponectin and tumor necrosis factor-αin favor of adiponectin,promoting considerable antioxidant effects and antidyslipidemic properties,and reducing hepatic triglyceride content which can prevent steatosis.The aforementioned mechanisms imply that ginger possesses interesting potentials for serving as a natural supplement for the prevention and treatment of NAFLD.Therefore,conducting trials to explore its benefits in clinical practice is greatly recommended.

The post-treatment data were obtained by measurements of surface microhardness and fluorescence methods.Data were statistically analyzed by ANOVA test with Tukey's honest significant difference test.Results: Enhanced remineralization was observed with several of the treatment systems including ginger + honey and rosemary. Significant differences between treatments were observed by microhardness and Fluore Cam fluorescence assesment, compared to the positive control group(Na F dentifrice). Significantly, greater remineralization was observed with the honey + ginger treatment regimen. No significant differences between groups were observed using the fluorescence assessment method, quantitative lightinduced fluorescence.Conclusions: Herbals(ginger, honey and rosemary) have enhanced remineralization of initial enamel lesion.

In vitro anti-hydatic and immunomodulatory effects of ginger and [6]-gingerol

Objective: To study in vitro anti-hydatic and immunomodulatory effects of ginger and [6]-gingerol as an alternative therapy for Cystic echinococcosis. Methods: Effect of a commonly used herbal product and ginger(Zingiber officinale) towards protoscoleces(PSC) and cyst wall in vitro was studied. The effect of [6]-gingerol, and the pungent constituent of ginger, was also evaluated on PSC culture. Furthermore, the activity of both extracts in association with interferon-gamma(IFN-γ) on PSC co-cultured with mononuclear cells of hydatic patients was evaluated. The nitric oxide(NO) production was measured in each co-culture. Results: Ginger exhibited a concentration- and time-dependent cytotoxic effect against PSC and cyst wall. Interestingly, ginger was more effective than the [6]-gingerol. Moreover, additional parasitic effect between extracts and IFN-γ are also observed in co-cultures. Furthermore, both extracts attenuated the NO production elicited by this infection or by the IFN-γ. Conclusions: Ginger has an important anti-hydatic effect in vitro. This effect is amplified in the presence of IFN-γ. Moreover, this herbal product may protect against host's cell death by reducing the high levels of NO. Ginger may act, at least, through the [6]-gingerol. All our data suggest the promising use of ginger in the treatment of Echinococcus granulosus infection.

Herbal extracts counteract cisplatin-mediated cell death in rat testis

Aim： To evaluate the protective effects of ginger （Gin） and roselle （Ros） against testicular damage and oxidative stress in a cisplatin （CIS）-induced rodent model. Their protective effects against CIS-induced apoptosis in testicular and epididymal sperms is also investigated. Methods： Ethanol extracts of Gin or Ros （1 g/kg.day） were given orally to male albino rats for 26 days. This period began 21 days before a single CIS intraperitoneal injection （10 mg/kg body weight）. Results： Gin or Ros given orally significantly restored reproductive function. Both tested extracts notably reduced the CIS-induced reproductive toxicity, as evidenced by restoring the testis normal morphology. In Gin and Ros, the attenuation of CIS-induced damage was associated with less apoptotic cell death both in the testicular tissue and in the sperms. CIS-induced alterations of testicular lipid peroxidation were markedly improved by these plant extracts. Conclusion： The present results provide further insights into the mechanisms of protection against CIS-induced reproductive toxicity and confirm the essential anti-oxidant potential of both examined extracts. （Asian J Androl 2008 Mar; 10： 291-297）
