Effect of ginger and P6 acupressure on chemotherapy-induced nausea and vomiting: a randomized controlled study.

OBJECTIVE: To evaluate the effect of ginger with P6 acupressure in preventing and treating chemotherapy-induced nausea and vomiting (CINV) in cancer patients. METHOD: A total of 172 participants were randomly divided into the control, ginger, acupressure, and joint groups, who were hospitalized in the Affiliated Hospital of Xuzhou Medical University from February and September 2022. The baseline characteristics, nausea, vomiting, and retching, benefit finding, functional living index-emesis, treatment satisfaction, and adverse reaction, were used in data collection. RESULTS: No significant difference was found in benefit finding and adverse reactions among the four groups (P > 0.05). Ginger significantly improved delayed CINV and function living index-nausea (P < 0.05) but had no significant effect on acute CINV, retching, and delayed vomiting, functional living index-emesis, and treatment satisfaction (P>0.05). Acute nausea and retching, delayed nausea, vomiting, and retching, functional living index-emesis, and treatment satisfaction were effectively improved in the acupressure and joint groups (P < 0.05). CONCLUSION: Ginger with P6 acupressure may contribute to improving CINV in patients undergoing chemotherapy.

The Effects of Body Fat Reduction through the Metabolic Control of Steam-Processed Ginger Extract in High-Fat-Diet-Fed Mice.

The prevalence of metabolic syndrome is increasing globally due to behavioral and environmental changes. There are many therapeutic agents available for the treatment of chronic metabolic diseases, such as obesity and diabetes, but the data on their efficacy and safety are lacking. Through a pilot study by our group, Zingiber officinale rhizomes used as a spice and functional food were selected as an anti-obesity candidate. In this study, steam-processed ginger extract (GGE) was used and we compared its efficacy at alleviating metabolic syndrome-related symptoms with that of conventional ginger extract (GE). Compared with GE, GGE (25-100 µg/mL) had an increased antioxidant capacity and α-glucosidase inhibitory activity in vitro. GGE was better at suppressing the differentiation of 3T3-L1 adipocytes and lipid accumulation in HepG2 cells and promoting glucose utilization in C2C12 cells than GE. In 16-week high-fat-diet (HFD)-fed mice, GGE (100 and 200 mg/kg) improved biochemical profiles, including lipid status and liver function, to a greater extent than GE (200 mg/kg). The supplementation of HFD-fed mice with GGE (200 mg/kg) resulted in the downregulation of SREBP-1c and FAS gene expression in the liver. Collectively, our results indicate that GGE is a promising therapeutic for the treatment of obesity and metabolic syndrome.

Zingiber Officinale Roscoe: The Antiarthritic Potential of a Popular Spice-Preclinical and Clinical Evidence.

The health benefits of ginger rhizomes (Zingiber officinale Roscoe) have been known for centuries. Recently, ginger root has gained more attention due to its anti-inflammatory and analgesic activities. Many of the bioactive components of ginger may have therapeutic benefits in treating inflammatory arthritis. Their properties seem especially helpful in treating diseases linked to persistent inflammation and pain, symptoms present in the course of the most prevalent rheumatic diseases, such as osteoarthritis (OA) and rheumatoid arthritis (RA). This review analyzes the current knowledge regarding ginger's beneficial anti-inflammatory effect in both in vitro and in vivo studies as well as clinical trials. The drug delivery systems to improve ginger's bioavailability and medicinal properties are discussed. Understanding ginger's beneficial aspects may initiate further studies on improving its bioavailability and therapeutic efficacy and achieving more a comprehensive application in medicine.

Effect of ginger supplementation on the fecal microbiome in subjects with prior colorectal adenoma.

Ginger has been associated with a decreased incidence of colorectal cancer (CRC) through reduction in inflammatory pathways and inhibition of tumor growth. Recent pre-clinical models have implicated changes in the gut microbiome as a possible mediator of the ginger effect on CRC. We hypothesized that, in adults previously diagnosed with a colorectal adenoma, ginger supplementation would alter the fecal microbiome in the direction consistent with its CRC-inhibitory effect. Sixty-eight adults were randomized to take either ginger or placebo daily for 6 weeks, with a 6-week washout and longitudinal stool collection throughout. We performed 16S rRNA sequencing and evaluated changes in overall microbial diversity and the relative abundances of pre-specified CRC-associated taxa using mixed-effects logistic regression. Ginger supplementation showed no significant effect on microbial community structure through alpha or beta diversity. Of 10 pre-specified CRC-associated taxa, there were significant decreases in the relative abundances of the genera Akkermansia (p < 0.001), Bacteroides (p = 0.018), and Ruminococcus (p = 0.013) after 6-week treatment with ginger compared to placebo. Ginger supplementation led to decreased abundances of Akkermansia and Bacteroides, which suggests that ginger may have an inhibitory effect on CRC-associated taxa. Overall, ginger supplementation appears to have a limited effect on gut microbiome in patients with colorectal adenomas.

Green-synthesized silver nanoparticles from Zingiber officinale extract: antioxidant potential, biocompatibility, anti-LOX properties, and in silico analysis.

INTRODUCTION: Zingiber officinale extract has emerged as a compelling candidate for green synthesis of nanoparticles, offering diverse applications across medicine, cosmetics, and nutrition. This study delves into the investigation of in vitro toxicity and explores the biomedical utility of green-synthesized silver nanoparticles derived from ginger extract (GE-AgNPs). METHODS: We employed established protocols to evaluate in vitro aspects such as antioxidant capacity, anti-inflammatory potential, and biocompatibility of GE-AgNPs. Additionally, molecular docking was employed to assess their anti-lipoxygenase (anti-LOX) activity. RESULTS: Our findings highlight that the extraction of ginger extract at a pH of 6, utilizing a cosolvent blend of ethanol and ethyl acetate in a 1:1 ratio, yields heightened antioxidant capacity attributed to its rich phenolic and flavonoid content. In the context of silver nanoparticle synthesis, pH 6 extraction yields the highest quantity of nanoparticles, characterized by an average size of 32.64 ± 1.65 nm. Of particular significance, GE-AgNPs (at pH 6) demonstrated remarkable efficacy in scavenging free radicals, as evidenced by an IC50 value of 6.83 ± 0.47 µg/mL. The results from the anti-LOX experiment indicate that GE-AgNPs, at a concentration of 10 µg/mL, can inhibit LOX activity by 25%, outperforming ginger extract which inhibits LOX by 17-18%. Notably, clionasterol exhibited higher binding energy and enhanced stability (-8.9 kcal/mol) compared to nordihydroguaiaretic acid. Furthermore, a cell viability study confirmed the safety of GE-AgNPs at a concentration of 17.52 ± 7.00 µg/mL against the L929 cell line. CONCLUSION: These comprehensive findings underscore the significant biomedical advantages of GE-AgNPs and emphasize their potential incorporation into cosmetic products at a maximum concentration of 10 µg/mL.

Zingiber officinale Root Capsule Extract Synergistically Enhance the Anti-Inflammatory Effects of Diclofenac Sodium in Experimental Acute Inflammation.

The present study aimed to evaluate the anti-inflammatory effects of ginger (Zingiber officinale) root capsule extract (GRCE) in doses of 100 mg/kg b.w. (body weight) and 200 mg/kg b.w. alone and in combination with a low dose (5 mg/kg b.w.) of diclofenac sodium (D) on carrageenan-induced acute inflammation (AI). The association of GRCE in a dose of 200 mg/kg b.w. with D offered the highest inhibition percentage for edema, reaching the maximum level of inhibition (95%) after 24 h. The association of GRCE in a dose of 200 mg/kg b.w. with D showed the ability to reduce tissue inflammatory changes when compared to D alone, while GRCE alone did not exhibit such properties. The association of both doses of GRCE with D showed significantly lower plasma and tissue levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1ß (IL-1ß) by up to 55% (p ≤ 0.0317), with the best results obtained by the group who received GRCE in the higher dose. These associations reduced the serum and tissue levels of prostaglandin-endoperoxide synthase 2 (COX-2) by up to 71% (p ≤ 0.0371). In conclusion, the association of GRCE with a low dose of D could be an appropriate combination to decrease the dose used to reduce serum and tissue levels of inflammatory molecules, edema, and histological changes in acute inflammation. Further research will be necessary to achieve clinical evaluation.

Extraction of High Value Products from Zingiber officinale Roscoe (Ginger) and Utilization of Residual Biomass.

Zingiber officinale Roscoe (ginger) is a plant from the Zingiberaceae family, and its extracts have been found to contain several compounds with beneficial bioactivities. Nowadays, the use of environmentally friendly and sustainable extraction methods has attracted considerable interest. The main objective of this study was to evaluate subcritical propane (scPropane), supercritical CO2 (scCO2), and supercritical CO2 with ethanol (scCO2 + EtOH) as co-solvent methods for the extraction of high value products from ginger. In addition, the reuse/recycling of the secondary biomass in a second extraction as a part of the circular economy was evaluated. Both the primary and the secondary biomass led to high yield percentages, ranging from 1.23% to 6.42%. The highest yield was observed in the scCO2 + EtOH, with biomass prior used to scCO2 extraction. All extracts presented with high similarities as far as their total phenolic contents, antioxidant capacity, and chemical composition. The most abundant compounds, identified by the two different gas chromatography-mass spectrometry (GC-MS) systems present, were a-zingiberene, ß- sesquiphellandrene, a-farnesene, ß-bisabolene, zingerone, gingerol, a-curcumene, and γ-muurolene. Interestingly, the reuse/recycling of the secondary biomass was found to be promising, as the extracts showed high antioxidant capacity and consisted of significant amounts of compounds with beneficial properties.

Use of ginger extract and bacterial inoculants for the suppression of Alternaria solani causing early blight disease in Tomato.

Early blight (EB), caused by Alternaria solani, is a serious problem in tomato production. Plant growth-promoting rhizobacteria promote plant growth and inhibit plant disease. The present study explored the bio-efficacy of synergistic effect of rhizobacterial isolates and ginger powder extract (GPE) against tomato EB disease, singly and in combination. Six fungal isolates from symptomatic tomato plants were identified as A. solani on the basis of morphological features i.e., horizontal septation (6.96 to 7.93 µm), vertical septation (1.50 to 2.22 µm), conidia length (174.2 to 187.6 µm), conidial width (14.09 to 16.52 µm), beak length (93.06 to 102.26 µm), and sporulation. Five of the twenty-three bacterial isolates recovered from tomato rhizosphere soil were nonpathogenic to tomato seedlings and were compatible with each other and with GPE. Out of five isolates tested individually, three isolates (St-149D, Hyd-13Z, and Gb-T23) showed maximum inhibition (56.3%, 48.3%, and 42.0% respectively) against mycelial growth of A. solani. Among combinations, St-149D + GPE had the highest mycelial growth inhibition (76.9%) over the untreated control. Bacterial strains molecularly characterized as Pseudomonas putida, Bacillus subtilis, and Bacillus cereus and were further tested in pot trials through seed bacterization for disease control. Seeds treated with bacterial consortia + GPE had the highest disease suppression percentage (78.1%), followed by St-149D + GPE (72.2%) and Hyd-13Z + GPE (67.5%). Maximum seed germination was obtained in the bacterial consortia + GPE (95.0 ± 2.04) followed by St-149D + GPE (92.5 ± 1.44) and Hyd-13Z + GPE (90.0 ± 2.04) over control (73.8 ± 2.39) and chemical control as standard treatment (90.0 ± 2). Ginger powder extracts also induce the activation of defence-related enzymes (TPC, PO, PPO, PAL, and CAT) activity in tomato plants. These were highly significant in the testing bacterial inoculants against A. solani infection in tomato crops.

Ginger-derived bioactive compounds attenuate the Toll-like receptor mediated responses of human dendritic cells.

Ginger has been used for thousands of years for the treatment of many illnesses, from nausea to migraines. Recently, an interest has grown in ginger compounds in the context of autoimmune and inflammatory diseases due to their significant anti-inflammatory effects. Nevertheless, the effects and mechanism of action of these phytochemicals in human immune cells, particularly in dendritic cells (DCs) are unclear. In the present study, we investigated the effects of 6-gingerol and 6-shogaol, the major compounds found in ginger rhizome, on the functionality of primary human monocyte-derived DCs (moDCs). Here we report for the first time that 6-gingerol and 6-shogaol dampen the immunogenicity of human DCs by inhibiting their activation, cytokine production and T cell stimulatory ability. In particular, the bioactive compounds of ginger dose-dependently inhibited the upregulation of activation markers, and the production of different cytokines in response to synthetic Toll-like receptor (TLR) ligands. Moreover, both compounds could significantly reduce the Escherichia coli-triggered cytokine production and T cell stimulatory capacity of moDCs. We also provide evidence that the ginger-derived compounds attenuate DC functionality via inhibiting the nuclear factor-κB (NF-kB), mitogen activated protein kinase (MAPK), and mammalian target of rapamycin (mTOR) signaling cascades. Further, 6-shogaol but not 6-gingerol activates the AMP-activated protein kinase (AMPK) and nuclear factor erythroid 2-related factor 2 (NRF2) pathways that might contribute to its anti-inflammatory action. Altogether, our results indicate that ginger-derived phytochemicals exert their anti-inflammatory activities via multiple mechanisms and suggest that 6-shogaol is more potent in its ability to suppress DC functionality than 6-gingerol.

Bitter ginger (Zingiber zerumbet) for patients with solid tumors with no treatment options: A pilot clinical study.

INTRODUCTION: Zerumbone is a natural compound found in bitter ginger plants (Zingiber zerumbet) that shows antiproliferative, antioxidant, anti-inflammatory, and analgesic properties. We aimed to investigate the role of zerumbone in improving the quality of life and symptom control in cancer patients with no treatment options. METHODS: We conducted a pilot, non-randomized, single-center, open prospective, and systematic study on the use of 400 mg of zerumbone twice a day. RESULTS: The study included 35 patients (mean age, 68 years; 64% men), of which 16 completed the eight-week study. The intention-to-treat population showed no significant changes in weight or sleep quality over the eight-week study. Assessments performed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) showed significant improvements in the quality of life in the global (p = 0.072), activity (p = 0.0393), social (p = 0.0001), and emotional (p = 0.0023) dimensions. The Hospital Anxiety and Depression Scale (HADS) questionnaire scores showed significant improvement in anxiety (p = 0.032) and depression (p = 0.021), while the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire scores also indicated a significant improvement (p = 0.001). Bitter ginger showed low toxicity. CONCLUSIONS: Bitter ginger showed promising results in improving the quality of life and reducing symptoms of anxiety and depression in the study population. A randomized placebo-controlled study is necessary to confirm these results. This trial was registered under the number FMABC: CAAE - 93459418.00000082, at ISRCTN (BIOMED CENTRAL) NUMBER 4388 (03/07/23) and at Plataforma Brasil (https://plataformabrasil.saude.gov.br/login.jsf).

In-vivo and in-silico studies to identify toxicity mechanisms of permethrin with the toxicity-reducing role of ginger.

In this study, the toxic effects of permethrin on Allium cepa L. and the protective role of Zingiber officinale rhizome extract (Zoex) were investigated. In this context, 6 different groups were formed. While the control group was treated with tap water, the groups II and III were treated with 10 µg/mL and 20 µg/mL Zoex, respectively, and the group IV was treated with 100 µg/L permethrin. The protective effect of Zoex against permethrin toxicity was studied as a function of dose, and groups V and VI formed for this purpose were treated with 10 µg/mL Zoex + 100 µg/L permethrin and 20 µg/mL Zoex + 100 µg/L permethrin, respectively. After 72 h of germination, cytogenetic, biochemical, physiological, and anatomical changes in meristematic cells of A. cepa were studied. As a result, permethrin application decreased the mitotic index (MI) and increased the frequency of micronuclei (MN), and chromosomal abnormalities. The increase in malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) and the decrease in glutathione (GSH) indicate that permethrin causes oxidative damage. Compared to the control group, a 68.5% decrease in root elongation (p < 0.05) and an 81.8% decrease (p < 0.05) in weight gain were observed in the permethrin-treated group. It was found that the application of Zoex together with permethrin resulted in regression of all detected abnormalities, reduction in the incidence of anatomical damage, MN and chromosomal aberrations, and improvement in MI rates. The most significant improvement was observed in group VI treated with 20 µg/mL Zoex, and Zoex was also found to provide dose-dependent protection. The toxicity mechanism of permethrin was also elucidated by molecular docking and spectral studies. From the data obtained during the study, it was found that permethrin has toxic effects on A. cepa, a non-target organism, while Zoex plays a protective role by reducing these effects.

Consequences of dietary cinnamon and ginger oils supplementation on blood biochemical parameters, oxidative status, and tissue histomorphology of growing Japanese quails.

The present study aimed to investigate the impact of various concentrations of ginger and cinnamon oils as antibiotic substitutes on some blood biochemical parameters, antioxidant capacity, and histopathological profile of the liver and gut of growing Japanese. A total of 900 Japanese quails were randomly allotted into 6 treatment groups. Each group had 5 replicates (30 chicks each). The first group received a basal diet and served as the control, while the second received a basal diet plus 0.5 g of colistin antibiotic/kg diet. The third and fourth groups were supplemented with 0.5 mL and 1.0 mL of ginger oil (GO)/kg diet, respectively. While the fifth and sixth groups received basal diet with 0.5 and 1.0 mL of cinnamon oil (CO)/kg diet, respectively. Results showed that adding herbal oils significantly (P < 0.05) decreased the aspartate aminotransferase (AST) and urea levels compared to control and colistin groups. Various levels of GO and CO significantly (P < 0.05) reduced cholesterol levels compared to control birds. Compared to the control and antibiotic groups, Japanese quails supplemented with various levels of herbal oils (GO and CO) had more extraordinarily significant (P < 0.05) values for total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GPX), and glutathione reductase (GSR). Regarding histopathologic examination, the jejunum displayed a nearly empty lumen, a few fusions, and mild goblet cell metaplasia. On the other hand, the duodenum looked tall and had a few fusions of villi and remnants of removal in its lumina. It could be concluded that cinnamon and GO improved birds' blood biochemical parameters, electorate oxidative stress, and enhanced intestinal and hepatic histology of the treated quails. Also, the levels of 0.5 mL CO and 0.5 mL GO may be an acceptable substitute for antibiotics (colistin) in the diets of growing Japanese quail.

Anti-Inflammatory Terpenoids from the Rhizomes of Shell Ginger.

Shell ginger (Alpinia zerumbet) is a perennial ornamental plant of ginger native to East Asia, which can be used as a flavoring agent in food or beverage, as well as a traditional Chinese medicine. In this study, a total of 37 terpenoids, including 7 new compounds, zerumin D1 to zerumin D7 (2, 3, 28-30, 36, and 37), and 5 new naturally occurring compounds, zerumin D10 to zerumin D14 (9, 12, 15, 20, and 24), were isolated and identified from the rhizomes of shell ginger. Compound 3 was an unprecedented variant labdane diterpenoid featuring a unique 6/7/6/3 tetracyclic cyclic ether system in its side chain. The anti-inflammatory activities of the isolated terpenoids were assessed in RAW 264.7 macrophages stimulated by lipopolysaccharide (LPS). Compound 4 significantly inhibited the production of nitric oxide with an IC50 value of 5.4 µM. Further investigation revealed that compounds 2 and 3 may inhibit the nuclear translocation of NF-κB, thus suppressing the expression of IL-6, IL-1ß, iNOS, and COX-2 to exert the anti-inflammatory effects.

Investigation on the Anticancer Activity of [6]-Gingerol of Zingiber officinale and its Structural Analogs against Skin Cancer.

INTRODUCTION: Skin cancer is the most common type of cancer caused by the uncontrolled growth of abnormal cells in the epidermis and the outermost skin layer. AIM: This study aimed to study the anti-skin cancer potential of [6]-Gingerol and 21 related structural analogs using in vitro and in silico studies. METHODS: The ethanolic crude extract of the selected plant was subjected to phytochemical and GC-MS analysis to confirm the presence of the [6]-gingerol. The anticancer activity of the extract was evaluated by MTT (3-[4, 5-dimethylthiazol-2-y]-2, 5-diphenyl tetrazolium bromide) assay using the A431 human skin adenocarcinoma cell line. RESULTS: The GC-MS analysis confirmed the presence of [6]-Gingerol compound, and its promising cytotoxicity IC50 was found at 81.46 ug/ml in the MTT assay. Furthermore, the in silico studies used [6]-Gingerol and 21 structural analogs collected from the PubChem database to investigate the anticancer potential and drug-likeliness properties. Skin cancer protein, DDX3X, was selected as a target that regulates all stages of RNA metabolism. It was docked with 22 compounds, including [6]-Gingerol and 21 structural analogs. The potent lead molecule was selected based on the lowest binding energy value. CONCLUSION: Thus, the [6]-Gingerol and its structure analogs could be used as lead molecules against skin cancer and future drug development process.

Ultrasound-assisted and subcritical water extraction techniques for maximal recovery of phenolic compounds from raw ginger herbal dust toward in vitro biological activity investigation.

This study examined the impact of two green extraction techniques in order to maximize the usage and recovery of phenolic compounds from the by-product of the filter tea industry, the so-called ginger herbal dust. The main phenolic compounds extraction was performed by ultrasound-assisted extraction (UAE) with the sonication amplitude ranging from 20% to 100%, and the subcritical water extraction (SWE), with the temperature ranging from 120 °C to 220 °C. All obtained extracts were characterized in terms of extraction yield, total phenolic content (TPC), and 6-ginerol, 6-shogaol, and 8-ginerol contents using RP-HPLC-DAD. Based on the results, we selected the extract obtained from raw ginger herbal dust using a sonication amplitude of 100% for further biological investigation of the cytotoxic effect on short- and long-term cell viability on liver and pancreatic cancer cells. This extract contained high TPC concentration, and 6-gingerol (44.57 mg/gDE), 8-gingerol (8.62 mg/gDE), and 6-shogaol (6.92 mg/gDE).

Ginger Supplementation Attenuated Mitochondrial Fusion and Improved Skeletal Muscle Size in Type 2 Diabetic Rats.

BACKGROUND/AIM: Oxidative stress, regulated by SOD2 and mitochondrial dynamics, contributes to muscle atrophy in diabetes. Ginger root extract (GRE) reduces oxidative stress. However, its effect on oxidative stress, mitochondrial dynamics, and muscle atrophy is not known in the diabetic muscle. This study examined the effect of GRE on intramuscular oxidative stress, mitochondrial dynamics, and muscle size in diabetic rats. MATERIALS AND METHODS: Twenty-six male Sprague-Dawley rats were randomly divided into control diet (CON; n=10), high-fat diet with one dose of 35 mg/kg streptozotocin (HFD; n=9), and high-fat diet with one dose of 35 mg/kg streptozotocin and 0.75% w/w GRE (GRE; n=7) fed for seven weeks. Subsequently, the muscle was analyzed for cross-sectional area (CSA), H2O2 concentration, and DRP-1, MFN2, Parkin, PINK1, SOD2 mRNA. Additionally, the protein levels of SOD2, DRP-1, DRP-1ser616, LC3AB, MFN2, OPA1, Parkin, and PINK1 were analyzed. CSA, H2O2 concentration, and gene and protein expression levels were analyzed using a one-way ANOVA. Correlations among intramuscular H2O2, CSA, and SOD2 protein were assessed using Pearson's bivariate correlation test. RESULTS: In the soleus, the GRE group had a greater CSA and lower intramuscular H2O2 concentration compared to the HFD group. Compared to the HFD group, the GRE group had higher SOD2 and DRP-1 mRNA levels and lower MFN2 and total OPA1 protein levels. H2O2 concentration was negatively correlated with CSA and positively correlated with SOD2. CONCLUSION: GRE attenuated intramuscular H2O2, mitochondrial fusion, and muscle size loss. These findings suggest that GRE supplementation in diabetic rats reduces oxidative stress, which may contribute to muscle size preservation.

Phytochemical profiling and anthelmintic potential of extracts of selected tropical plants on parasites of fishes in Epe Lagoon.

This research aims to study the anthelmintic properties of selected five (5) tropical plant extracts, ascertained margin of fish host safety in reference with praziquantel, a commonly used chemo-therapeutics. Qualitative and quantitative analysis of Alligator pepper seeds (Aframomum melegueta), Moringa leaves (Moringa oleifera), Neem leaves (Azadirachta indica), Ginger bulbs (Zingiber officinale) and Garlic (Allium sativum) and their potencies in reference to praziquantel against Clarias gariepinus and different classes of helminth parasites were investigated. The results obtained show that the 70% ethanol extract had 80 to 100% presence of the phytochemical content, compared with the 100% aqueous and 100% ethanol extracts with 50 to 80% and 50 to 90%, respectively. Among the five tropical plants, the richest in saponin and flavonoids are alligator pepper and neem with alkaloids, tannin, flavonoid and saponin in ratios 1:1:3:9 and 1:1:4:3 respectively. While, moringa, garlic and ginger are rich in alkaloids with alkaloids, tannin, flavonoid and saponin in ratios, 8:1:10:1, 6:2:1:4 and 6:3:2:1, respectively. Aframomum melegueta and praziquantel showed above 70% potency (at 96 h LC5) against all the classes of parasites; Wenyonia spp (cestode), Procamallanus spp (nematode), Tenuisentis spp (acanthocephalan), and Electrotaenia sp (cestode) as compared to the other plant extracts that showed above 70% potency (at 96 h LC5) only against Electrotaenia spp. Sub-lethal Concentrations (96 h LC5) of praziquantel and Aframomum melegueta on the juvenile fish host (12.36 mg/l and 9.9 mg/l respectively) were found to be 90.9% and 93.5% effective against adult Electrotaenia spp after 8 to 10 min of exposure. These concentrations were 78 to 85.7% and 89.7 to 88.4%, respectively, effective against the other classes of parasites after 18 to 25 min and 15 to 21 min of exposure. These concentrations were tested on the post juvenile of the fish to determine behavioral changes; there were no significant behavioral responses after 24 h of exposure. The effective concentrations indicate the widest margin of safety for the fish host.

Effect of Zingiber Officinale in the Management of Nausea and Vomiting Induced by Treatment With Cisplatin Associated With Radiotherapy: A Randomized Controlled Trial.

OBJECTIVE: evaluate the efficacy of Zingiber Officinale in the management of nausea and vomiting induced by treatment with cisplatin associated with radiotherapy in patients with uterine cervical neoplasms. METHODS: a triple-blind, randomized, placebo-controlled trial. Interventions: Comparing the effects of ginger with institutional antiemetic therapy (ondansetron with dexamethasone). Patients with cervical cancer who started treatment with cisplatin with an indication of 40 mg/m² associated with radiotherapy, aged over 18 years, and with the ability to tolerate swallowing a capsule were recruited and equally allocated (1:1:1) into 3 groups of 16 patients each (the ginger capsules 250 mg group, ginger capsules 500 mg group, and placebo group). Nausea and vomiting were measured on baseline, 7 days after the first dose of medication and every seven consecutive days during a treatment break. RESULTS: The 250 mg ginger group had an 8.0% greater chance of experiencing nausea within 24 h after the chemotherapy infusion than the placebo group, although there is no statistical significance (P = .92986). The 500 mg ginger group showed a 63.9% reduction in nausea under the same conditions (P = .40460). No change was detected in the occurrence of nausea episodes during the 6 weeks (P = .8664) or between the groups (P = .2817). No change was detected in acute or late vomiting during the 6 weeks (P = .3510) or between the groups (P = .8500 and P = .5389, respectively). CONCLUSION: Ginger supplementation does not reduce the intensity of acute and late nausea and vomiting. REBEC (RBR-47yx6p9).

Research progress on ginger polysaccharides: extraction, purification and structure-bioactivity relationship.

Ginger is a widespread source of herbal medicine and traditional spices. Among its various bioactive components, ginger polysaccharides (GPs) have attracted the attention of researchers worldwide because of their significant bioactivity. Recent studies have demonstrated the antioxidant, antitumour, anti-inflammatory, immunomodulatory, hypoglycaemic, cough suppressant and thrombotic anticoagulant effects of GPs. However, the structure-bioactivity relationship of GPs has yet to be comprehensively investigated. This review aims to explore all the current published studies on GPs. It further examines various aspects, including the extraction and purification methods, structure, bioactivity, application and structure-bioactivity relationship of GPs. Thus, this review intends to provide a reference for future GP-related research and development.
