Aqueous extract of Bulbine natalensis Baker (Asphodelaceae) stem at 25, 50 and 100 mg/kg body weight was investigated for anabolic and androgenic effects in male Wistar rats. Sixty male rats were grouped into four (A-D) consisting of 15 each. Group A (control) was orally treated with 0.5 mL of distilled water for 14 days while groups B, C and D were treated like the control except they received...

Aminophylline (50-100 mg/kg) and strychnine (0.125-0.5 mg/kg) significantly raised the ED50 values of LY 300164 against maximal electroshock in mice, from 4 to 8 mg/kg (aminophylline 100 mg/kg) and from 3.6 to 11.5 mg/kg (strychnine 0.5 mg/kg). Also, aminophylline (25-50 mg/kg) and strychnine (0.125-0.25 mg/kg) increased the ED50 value of lamotrigine in this test, for instance from 5.5 to 8.0 m...

The chemotherapeutic activity of minocycline, a semi-synthetic tetracycline analogue, was evaluated in a murine model of toxoplasmosis. A lethal acute toxoplasmosis was produced by injecting 10(5) tachyzoites of the RH strain of Toxoplasma gondii into the peritoneal cavities of Swiss-Webster mice. When infected mice were treated once daily for 12 days, starting 2 h after challenge, the survival...

BACKGROUND One of the considerable uses of lettuce (Lactuca sativa) seed in traditional medicine has been to reduce semen, sperm and sexuality. OBJECTIVE The aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis.

In present experimental study gross, histopathological and different serum biochemical effects of malathion were observed in male Japanese quail. For this purpose apparently active and sexually mature male Japanese quail (approximately 5-6 weeks and each group 15 birds) were kept in six groups (A-F). Malathion @ 0, 25, 50, 75, 100 and 125 mg/kg b.w mixed in corn oil was administered orally for ...

Fluconazole and amphotericin B were compared in the prophylaxis and treatment of Candida albicans aortic endocarditis in a rabbit model. In the prophylaxis study, catheterized rabbits received, prior to intravenous (i.v.) challenge with C. albicans (2 x 10(7) blastospores), either no therapy, single-dose i.v. amphotericin B (1 mg/kg of body weight), single-dose fluconazole (50 mg/kg or 100 mg/k...

PURPOSE Inhibitors of farnesyltransferase (e.g., R115777) are being developed for therapy and prevention of various cancers. The efficacy of R115777 [Zarnestra; (B)-6-[amino(4-chlorophenyl)(1-methyl-1H-imidazol-5-yl)-methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone] to prevent the development of lung tumors in mice was determined. EXPERIMENTAL DESIGN Female strain A mice (7-8 weeks of ag...
