(1) Immunocytochemical localization of 5 alpha-reductase was studied in various tissues using polyclonal antibodies against type 1 and 2 isozymes.(2) In the rat anterior pituitary, type 1 isozyme was present in the membrane of rough endoplasmic reticulum of gonadotrophs.(3) In the rat adrenal cortex, zonae fasciculata-reticularis cells contain 5 alpha-reductase type 1. The expression of the enzyme increased in the castrated animals. This indicates that sex steroids play a role in the regulation of corticoids secretion and metabolism.(4) In the rat adrenal medulla, 5 alpha-reductase type 1 was present in the supporting cells surrounding chromaffin cells and Schwann cells around nerve fivers.(5) Steroid 5 alpha-reductase was present in the satellite cells in the ganglions in addition to Schwann cells.(6) In the human prostate, seminal vesicle and vas deferens, type 2 isozyme was present in the basal epithelial cells and smooth muscle cells in the interstitial tissue.(7) Leucocyte type arachidonate 12-lipoxygenase was immunolocalized in the secretory cells of pig anterior pituitary gland and neutrophils of dog.(8) Platelet type arachidonate 12-lipoxygenase was immunocytochemically localized in the plateletes and eosinophils of the peripheral blood, megakaryocytes of the bone marrow, and keratinocytes of the epidermis.

（1）使用针对1型和2型同工酶的多克隆抗体在各种组织中研究了5种α-还原酶的免疫细胞化学定位。（2）在大鼠前垂体前垂体中，在粗糙的肿瘤肿瘤的膜中存在于1型垂体前垂体。 fasciculata-reticularis细胞含有5种α-还原酶1型。剥离动物中酶的表达增加。这表明性类固醇在调节皮质素的分泌和代谢中起作用。（4）在大鼠肾上腺髓质中，在围绕神经纤维周围的铬蛋白细胞和schwann细胞周围的支撑细胞中存在5种α-还原酶1型1型。前列腺，囊泡和VAS递延，在基础上皮细胞中存在2型同工酶和间质组织中的平滑肌细胞。（7）在猪后垂体和中性脑中中性脑中的分泌细胞中，将白细胞型蛛网膜型12-脂氧酶进行了免疫细胞（8） - 8），arach cartect of dog（8）。免疫细胞化学定位于外周血的血小板和嗜酸性粒细胞中，骨髓的巨核细胞和表皮的角质形成细胞。
