成熟麝香、白香及麝鼠香的扫描电镜观察研究

Scanning Electron Microscope Observation of Mature Musk,White Musk and Muskrat Musk

通过光学显微镜观察与电镜扫描对比分析成熟麝香、白香和麝鼠香3种样品之间的差异,并对林麝香囊皮肤进行了观测,旨在探究麝香的生理分泌机理.结果表明:成熟麝香主要由10~200μm不规则云状团块组成,在团块上附着或者周围散布着较为模糊的星云状物质.白香的均一性较好,光镜下显示为高密度星云状,电镜下呈现为葡萄状样颗粒簇,单一颗粒直径约为0.2μm,夹杂少许椭球形细胞结构和干酪样不规则团块.麝鼠香视野在电镜下较为模糊,但也呈现为葡萄状样颗粒簇,单一颗粒大小为0.5~2μm.林麝香囊颈部皮肤存在多个约2 mm^(2)的排泄小孔,直径约100μm.香囊内壁皮肤也观测到少许20~100μm的排泄小孔.

In this study,the differences among mature musk,white musk and muskrat musk samples were compared and analyzed by optical microscope observation and electron microscope scanning.In the meanwhile,the skin of the sachet was observed to explore the physiological secretion mechanism of musk.Results indicate that mature musk is mainly composed of 10~200 μm irregular clouds-like clusters,with relatively blurry nebular like substances attached to or scattered around the clusters.The uniformity of white musk is good,and it appears as a high-density nebula under light microscopy.While the white musk appears as a grape-like particle cluster with a single particle diameter of about 0.2 μm and mixed with a few ellipsoidal cell structures and cheese-like irregular clumps under electron microscopy.The view of muskrat musk under electron microscopy is relatively blurry.It presents as grape-like particle clusters,with a single particle size of 0.5~2 μm.There are multiple excretory pores of approximately 2 mm~2 on the neck skin of the sachet,with a diameter of 100 μm.A few excretory pores of 20~100 μm were also observed on the inner skin of the sachet.
