Correlation between brain arteriolar sclerosis degree and cerebral infarction at different brain region 脑内不同节段小动脉硬化程度差异与脑梗死的相关性

The arteriolar sclerosis that results from chronic hypertension leads to small lacunar infarcts , or " lacunes " , one of which is seen here in the pons 缓进型高血压小动脉硬化导致小范围的腔隙性梗死灶,脑桥上可见一此种病变。

Renin secretion is controlled by at least four mechanisms that are not mutually exclusive : a renal vascular receptor responds to changes in tension in the afferent arteriolar wall ; a macula densa receptor detects changes in the delivery rate or concentration of nacl in the distal tubule ; circulating angiotensin has a negative feedback effect on renin secretion ; and the sympathetic nervous system stimulates renin secretion via the renal nerve mediated by receptors 肾素的分泌至少受四种互不排斥的机制控制:肾血管受体对向心小动脉壁张力变化的反应;致密斑受体发现远端肾小管内氯化钠传递速率或浓度的变化;循环的血管紧张素对肾素的分泌的负反馈效应;和交感神经系统经由受体介导的肾神经刺激分泌肾素。

The results show that : the glomerulus of the mouse consists of a lobular arteriole within the glomerulus , capillary meshwork lobules and communication branches between the lobules and the efferent arteriolar roots ; there are some sublobular microcirulatary units in lobules ; the glomerulus of chrysolophus pictus is only a tortuous vascular ball ; there are no branches anastomosed between the vascular ; the afferent arteriole is a branch , efferent arteriole is one either , but some efferent arteriole has branches 结果表明:小白鼠肾小球由小球内小叶微动脉、毛细血管网小叶及小叶间交通支和小叶输出血管构成,小叶可分出亚单位;红腹锦鸡肾小球为一簇迂回盘曲的血管团,血管间未见有复杂的分支和吻合;小白鼠和红腹锦鸡入球小动脉和出球小动脉均为一支,但有的出球小动脉有分支。
