麝泌香盛期麝香腺超微结构和麝香分泌研究

雄麝特有的麝香腺,由于分泌行使化学通讯机能的信息素(Pheromone)麝香,结构特异。长期以来,国内外对麝香腺的结构和麝香分泌研究甚少,只有解剖学方面的简单描述,故对麝香分泌机理和泌香规律众说纷纭。我国最早(1958)进行过人工养麝和活体取香。随着养麝业的发展,近年对麝香腺进行了解剖、组织学(毕书增等,1980;冯文和等,1981;郑生武等,1984)和泌香机理研究(毕书增等,1980;李复东,1980;颜于宏等,1981),对麝香的分泌、形成与泌香规律有了进一步的认识,但缺乏全面系统的研究,特别在超微结构的研究方面尚属空白。

STUDY ON ULTRASTRUCTURE OF MUSK GLAND AND MUSK SECRETION

In the middle stage of vigorous period of musk secretion, all the dark cells and clear cells secrete a number of special granules,the numbers of special granules respectively are 4.5 and 7.5 times as high as that in nonvigorous period, the mitochondrion and the microvilli of intercellular and intracellular tubules are abundant. In the later stage of vigorous period of musk secretion, the special granules are rare, while rough endoplasmic reticulum and ribosomes are abundant, it hints that the secretion of protein is vigorous.There are three secretory ways of epithelial cell in musk gland: 1. Macroapocrine, 2. Microapocrine, 3. Merocrine in molecular level.The observations cf electron microscope prove: Musk gland is a special gland, that has characteristics of ordinary sweat gland and odoriferous sweat gland.
