Methods: Adult male Wistar rats were used. In the acute study, 20 rats were randomly divided into 5 groups of 4 animals each. Four treated groups were administered orally a single dose of Mondia whitei (400 mg/kg) and the controls received a similar amount of distilled water. One group of animals were sacrificed by cervical dislocation 1,2,4 and 6 h after treatment, respectively. The controls were sacrificed at 6 h. Testicular testosterone was determined by radioimmunoassay. In the chronic study, 28 rats were divided at random into 4 groups of 7 animals each: Groups 1, 2 and 3 were given orally the plant extract (400 mg·kg-1·day-1) for 2, 4 and 8 days, respectively. The animals of Groups 1 and 2 were sacrificed 24 hours after the last dosing. The controls (Group 4) received the same amount of distilled water for 8 days. The fertility was assessed only in Groups 3 and 4 and after that, the animals were sacrificed and the epididymal sperm density, the serum testosterone and the testicular testosterone and 17β-estradiol were assayed. The serum, testicular and epidydimal protein contents were also determined. Results: In the acute treatment groups, the serum and testicular concentrations of testosterone remained unchanged at all the time points. Chronic treatment for 8 days induced a significant increase in the testicular weight, the serum and testicular testosterone, the testicular protein content and the sperm density (P<0.05-0.01), but did not affect the accessory gland weights, the serum protein contents, the testicular concentration of 17β-estradiol and the fertility compared to the controls. Conclusion: Mondia whitei root extract possesses an androgenic property.展开更多

There was no mouse dead after given with VUKA extracts during the time course, so the LD50 of water-extracted and freeze-dried powder of VUKA was estimated over 15 g/kg body weight for mice. No significant lesions of brain, heart, liver, kidney, spleen and thymus were found at gross and histopathological observation in the treated mice. Hematological parameters included of WBC, RBC, HGB, HCT, MCV, MCH, MCHC and PLT values were as normal as control. Besides, serum biochemistry changes in liver and renal function included of ALT, AST and creatinine values had no significant difference (p＞0.05) with control.展开更多
