现将我们对牛黄进行显微鉴别的一些做法和发现介绍如下,供同志们参考。一、天然牛黄:取本品粉末,以50%甘油酒精液装片(加一滴50%甘油酒精液于载玻片上,用细玻棒蘸取少量牛黄粉末,放在甘油酒精液中,调匀,盖上盖物玻片)。置显微镜下观察,可见大量大小不等的不规则形团块,大的团块呈云朵状、絮状、或破碎的泥块状,直径可达100微米左右,棕褐色至褐黑色,不透明或边缘微透明;小块的呈不规则形或类圆形、长圆形,以不规则形者为
Here are some of the practices and findings of our microscopic identification of bezoar as follows for reference by comrades. First, natural bezoar: Take this product powder, loaded with 50% glycerol alcohol solution (add a drop of 50% glycerol alcohol solution on a glass slide, use a fine glass rod to take a small amount of bezoar powder, placed in glycerol alcohol, and mix thoroughly, Cover the cover glass). Observed under the microscope, there are a large number of irregular shaped masses ranging in size from one another. The large masses are cloud-like, floc-like, or broken mud masses, with a diameter of up to 100 microns, brown to brownish black, opaque or The edges are slightly transparent; small pieces are irregular or round, oblong, irregular
