RESUMEN
Background: To assess the median lethal dose and evaluate the anti-chemotherapeutic effects of hydro-methanolic root extract of Glycyrrhiza glabra on the cyclophosphamide (CP) induced mutagenicity in bone marrow cells of Swiss albino mice. Methods: For the assessments of LD50, hydro-methanolic root extract of Glycyrrhiza glabra were intra-peritoneally administered at doses of 200, 400, 600, 800, 1000, and 1200 mg/kg body weight. For the mutagenicity study, bone marrow micronucleus test was used and the single i.p. of Glycyrrhiza glabra extract given at the dose of 300, 450, and 600 mg/kg body weight, 24 hrs prior the administration of CP (at the dose of 50 mg/kg body weight). Results: The present investigations revealed that, the median lethal dose/LD50 was observed at the dose of 833.3 mg/kg body weight. The results suggest that, the doses of 450 and 600 mg/kg body weight expressed signifi cant preventive potential against CP induced Micronucleus formation in student ‘t’ test at dose dependent manner in the bone marrow cells of Swiss albino mice. Glycyrrhiza glabra root extract alone has not induced micronucleus formation. Conclusion: Based on this study, it may be concluded that Glycyrrhiza glabra root extract possess anti-mutagenic behavior and this hydro-methanolic crude extract may be safe as per the LD50 was observed.
RESUMEN
Background: Cyclophosphamide (CP), [2-(bis-/2-chloro-ethyl-amino)-tetrahydro-2H-1, 2, 3 oxazaphosphorine-2-oxide], is an alkylating chemotherapeutic agent, which is commonly used against malignancies, such as leukemia, lymphoma, breast, lung, prostrate, and ovarian cancer. The aim of this study is to evaluate the side effect of CP on male albino rat in response to certain hematological and hepatic and renal biochemical parameters. Methods: In this investigation, total 20 albino rats were divided in to two groups of ten each. Group first served as control received i.p. injection of 0.9 physiological saline fed with standard food and water ad libitum. While, Group second received a single dose (0.4ml/100g b/w) through i.p. injection of cyclophosphamide once in a week for a period of 7 and 35 days and hematological parameters i.e. Hb%, total count-RBCs, total count-WBCs along with some biochemical estimations i.e. protein and creatinine levels in liver and kidney were quantified after 7 and 35 days of the treatments. Results: The hematological parameters i.e. Hb%, total count-RBCs, total count –WBCs and protein and creatinine levels in liver and kidney were significantly lowered after 7 and 35 days treatment of cyclophosphamide. The lowering of these values was more prominent in later part of the experiment. Conclusion: Alteration in hematological parameters after cyclophosphamide exposure may impair the functional activities of liver and kidney of male Rattus norvegicus by interfering enzymatic metabolic activities and protein synthesis.
RESUMEN
The present investigation is aiming at studying the effect of oral administration of aspirin (acetylsalicylic acid, ASA) drug on female albino rat, Rattus rattus norvegicus. The female rats (n=24) were allocated into 2 groups as control and treated. The treated rats (n=12) were given orally with high dose of aspirin at a dose of 100 mg/ kg body weight for 15 days (n=6) and 30 days (n=6). And body weight, relative organ weights, hematological parameters such as Hb %, total count RBC and total count WBC; and biochemical estimations in blood serum such as glucose, protein, cholesterol and calcium were measured. The aspirin did not showed much significant variations in the body weight, relative organ weights, serum protein, serum cholesterol, serum calcium, total counts RBC and Hb %; while, aspirin declined serum glucose level and elevated total count of WBC. The present investigation indicated that the aspirin impairs serum glucose level and total count of WBC by modulating of certain enzymes metabolism in albino rats.
