Introduction: The impact of sub-acute administration of purified gambier (Uncaria gambir Roxb.) to the liver and kidney function and its reversibility had been studied on rats. Methods: Rats at the aged of 2-3 months and the bodyweight of ±250 g were treated with water solution of purified gambier at the dose of 5 mg/kg10 and 20 mg/kg for 7 to 14 consecutive days. Plasma ALP, AST activities, creatinine clearance, liver and kidney ratios were determined on the day 1, 7, 14 one week after the doses stopped. All data on each parameter were analyzed using two-way ANOVA followed by Duncan's multiple T-test and significance was taken at p<0.05. Results: The results showed that all parameters was not affected significantly (p>0.1), except ALT activity and liver organ ratio decreased significantly (p<0.05). Conclusion: These indicated that purified gambier is relatively non-toxic to the liver and the kidney of the rats at doses of 5-20 mg/kg BW for 14 days.
Hematotoxicity study of butanol fraction of Cassytha filiformis L. on white male mice has been performed. A total of 12 white male mice were used, and they were divided into four groups. Each group consists of 3 mice. These animals were treated with Cassytha filiformis L. butanolic fraction at several doses of 2.5, 5, and 10 mg/kg for seven days. Hemoglobin value, erythrocytes, platelets, leukocytes, monocytes, lymphocytes, eosinophils, neutrophils, and basophils counts were measured at the 1 st , 3 rd, and 7 th day of treatment. The data of this study were analyzed using two-way ANOVA, followed by Duncan's multiple region tests. The results showed that the doses of butanol fraction did not affect hemoglobin value, erythrocytes, leukocytes, and neutrophils (p >0.1), but it significantly reduced platelet, monocyte, lymphocyte count, and increases eosinophils (p <0.01) counts within their normal limits. There is no influence on the duration of administration and the interaction of dosage, and also the duration of use of the parameters above. This result implies that the Cassytha filiformis butanol fraction at doses of 2.5-10 mg/kg does not affect hematology parameters if it were used for seven days.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
