Toxicity studies on turmeric (Curcuma longa): acute toxicity studies in rats, guineapigs & monkeys

Abstract: Acute toxicity studies conducted on different species of animals, including non-rodents, indicated that turmeric or its alcoholic extract was not toxic, even when consumed at the very high levels of 2.5 g/kg or 300 mg/kg body wt., resp.

Vasectomy & biochemical composition of human seminal plasma.

Abstract: This study attempts to analyze the levels of lipid P (phosphorus); Na (sodium); K (potassium) and Zn (zinc) in the seminal plasma of normal vasectomized and azoospermic males. Semen samples were obtained from normal healthy and vasectomized (6 months to 2 years) male volunteers by masturbation. P lipid levels were determined by the method of Youngberg as modified by Hawk et al. Na and K levels were measured by EEL flame photometer while Beckman-495 was used to measure Zn level. Lipid P levels were significantly higher in seminal plasma of azoospermic and vasectomized male subjects ( p < 0.001) than that of controls. A highly significant increase of Na was seen in the azoospermic group while Na levels in the seminal plasma of both groups remained the same. No effect on K levels were detected. Significantly lowered levels of Zn (p < 0.02) were seen in the seminal plasma of both groups (p < 0.02).
