Scanning electron microscopy studies of the vascular pole of the rat glomerulus

摘要: The vascular poles of 30 renal corpuscles were studied in critical-point dried cortex the Munich-Wistar rat by scanning electron microscope (SEM). In 28 cases one afferent and efferent arteriole observed; was done Sprague-Dawley rat, where 34 examined. One a single found 32 cases; case only two arterioles observed. another it questioned whether or double is present. addition, specimens allowed an evaluation area extraglomerular mesangium passes into mesangial cells glomerular tuft. This to be rather small represent "punctum fixum" for contraction entire mesangium.
