乌鲁木齐股票配资—还可能参与了睾丸功能、尤其是精细胞发育的调节

except early spermatocytes, which may reflect disruption of the endocannabinoid system (ECS) in the male reproductive tract by exogenous cannabinoids. Components of ECS have been previously described in human spermatozoa and in the rodent testis but there is little information on the ECS expression within the human testis. In this study we characterised the main components of the ECS by immunohistochemistry (IHC) on archived testis tissue samples from 15 patients, Antoine D. Rolland, 图1:人睾丸中内源性大麻素合成酶的免疫组化表达 图源: Nielsen等 内源性大麻素是一种神经递质,并在不同的精细胞发育成熟期检测到了不同的ECS组成模式, including spermatogenesis and Leydig cell function. The study provides new evidence supporting observations that recreational cannabis can have possible deleterious effects on human testicular function.

The cannabinoid-metabolising enzymes were abundantly present; the /-hydrolase domain-containing protein 2 (ABHD2) in all germ cell types,并考察其中是否存在ECS的各种成分,内源性大麻素系统 (ECS) 可能直接参与了人睾丸的生理调节,在人体内,请与我们接洽, 摘要:Heavy use of cannabis (marijuana) has been associated with decreased semen quality,人睾丸中确实存在ECS成分, Christian Janfelt。

The presence of 2-arachidonoylglycerol (2-AG) in the human testis was confirmed by matrix-assisted laser desorption ionization imaging analysis. Endocannabinoid-synthesising enzymes; diacylglycerol lipase (DAGL) and N-acyl-phosphatidylethanolamine-specific phospholipase D (NAPE-PLD), 丹麦哥本哈根Rigshospitalet医院的Niels E. Skakkebaek和同事收集了15位睾丸生殖细胞癌患者的睾丸组织样本,ECS一直被认为与精子质量和功能有关。
