AIMto investigate the effects of crude garlic on adult male rat reproductive functions.

METHODSThirty male rats were divided into five groups: group 1 (untreated) and groups 2, 3, 4 and 5 were fed for 30 days with 5%, 10%, 15% and 30% crude garlic, respectively. Testes and accessory organs were weighed and some markers were assessed. Light and electron microscopy observations were also performed.

RESULTSA significant decrease was observed in the body weight of groups 4 (14%; P < 0.01) and 5 (20%; P < 0.01); of the prostate weight in group 5 (29.1%; P < 0.05) and of seminal vesicle weight in groups 3 (14.4%; P < 0.01), 4 (18.3%; P < 0.01) and 5 (27.3%; P < 0.01). In contrast, testis and epididymis weights were unchanged. In epididymis tissue, the alpha glucosidase activity and the spermatozoa density were unchanged. The treatment resulted in a significant decrease in testosterone serum levels in groups 3 (77.3%; P < 0.01), 4 (77.3%; P < 0.01) and 5 (90.9%; P < 0.01), associated with a significant increase in LH serum levels (P < 0.01). Testicular histology showed a dose-dependent increase in the percentage of empty seminiferous tubules. Moreover, testicular function was affected; a significant decrease in phosphatase acid activity (P < 0.01) and testosterone (P < 0.05) contents were observed.

CONCLUSIONCrude garlic consumption during 1 month reduced testosterone secretion and altered spermatogenesis at 10%, 15% and 30% doses.

Introduction: Smoking is associated with a higher risk of mortality, especially in smokers with cardiovascular and respiratory diseases. Smoking cessation remains the most effective approach in reducing smoking-related illness risks at all ages. For elderly smokers, smoking cessation has been proved to prolong life expectancy and reduce the risk of stroke and ischemic heart disease. However, a wide selection of smoking cessation medications makes prescribing challenging, especially among elderly smokers. Inability to recommend the best treatment may reduce the smoking cessation success rate in the elderly. Therefore, this study compares the effectiveness of pharmacotherapy available and correlate the effect of ageing on the effectiveness, leading to the recommendation of the best medication for elderly smokers. Method: A systematic searching strategy was performed in three different databases by using predetermined search strings. Results: Overall, this systematic review revealed that varenicline showed the greatest smoking cessation rate among the elderly, followed by bupropion and NRT. Conclusion: It is suggested that varenicline offered the best medical aid for smoking cessation in the elderly.
