肾上腺髓质内产生去甲肾上腺素和肾上腺素的两种细胞超微结构,依动物种属和样品制作方法不同而略有差别。我们对正常成龄雄性猕猴用4%戊二醛和2%多聚甲醛磷酸缓冲液进行灌流固定,取肾上腺髓质,后固定用1%锇酸(Millonig 法),国产环氧树脂618包埋,超薄切片后用醋酸铀及枸橼酸铅双重电子染色,电镜观察结果如下: Adrenal medulla produce norepinephrine and epinephrine two cell ultrastructure, according to animal species and sample preparation methods vary slightly. We normal-aged male monkeys with 4% glutaraldehyde and 2% paraformaldehyde phosphate buffer perfusion, take adrenal medulla, fixed with 1% osmium tetroxide (Millonig method), made of embedded epoxy 618 , Ultra-thin slices with uranyl acetate and lead citrate double electronic staining, electron microscopy observations are as follows:
