本实验用组织化学、电镜和生化测定方法研究了人和大鼠输精管的平滑肌和神经分布。结果表明;大鼠输精管的神经密度明显高于人,轴索数/100个肌细胞断面,大鼠是118,人是315肌-神经间隔,大鼠是25nm左右,人是100nm左右;肌细胞外间隙(％),大鼠是12.9,人是35.8;肾上腺素能神经支配占优势,乙醛酸诱发荧光法显示大鼠输精管肌层内有致密的肾上腺素能神经纤维,ACh阳性反应神经较少,主要分布于固有层,人输精管中上述两种神经均较少;每克湿组织中NE含量(ng)大鼠约为人的10倍左右(大鼠:2369.35±820.27,人:294.66±83.90);电镜观察,SGV型神经终末支多见。
In this study, histochemistry, electron microscopy and biochemical methods to study the human and rat vas deferens smooth muscle and nerve distribution. The results showed that the neural densities of rat vas deferens were significantly higher than those of human. The number of axons per 100 myocytes was 118 in rats, 315 in muscle-nerves interval, about 25 nm in rats and about 100 nm in humans. The outer gap (%) was 12.9 in rats and 35.8 in humans. Adrenal nerve predominance was predominant. Glyoxylate-induced fluorescence showed dense adrenergic nerve fibers in the muscle layer of the vas deferens. Less in the lamina propria, and less in the human vas deferens; about 10 times more NE in rats per gram of wet tissue (rats: 2369.35 ± 820.27, 294.66 ± 83.90 ); Electron microscopy, SGV-type nerve terminal more common.
