作者等在21例裴氏着色真菌病、紧密着色真菌病及卡利翁氏分枝孢子菌病患者中取其损害中的黑点,放在载玻片上,加一滴二甲基亚砜一氢氧化钾溶液,2分钟后即可在低倍显微镜下检查到着色真菌病致病菌的孢子。这种黑点是真菌与宿主相互作用发生炎症加出血而随着小脓疡通过表皮嵌入异常的角层所形成,在显微镜下有如凝血块的红色,一般增殖性结节中易于见到,在环状及萎缩斑型着色真菌病的损害中较少见到,在病理切片及在培养时均不易找到真菌,但如果有黑点即可找到真菌。
The authors in 21 cases of Pei’s colored fungal disease, close-colored fungal disease and Corynebacterium parvum disease patients take their damage black spots, on a glass slide, add a drop of dimethyl sulfoxide hydrogen Potassium oxide solution, after 2 minutes under low magnification microscope to check the fungal pathogenic bacteria fungal spores. This black spot is the interaction of the fungus and the host inflammation plus bleeding with the small abscess through the epidermis embedded in the abnormal corner of the formation of a microscope, such as clot red, general proliferative nodules easily seen in the Lost in circular and atrophic stains of colored mycotic disease is less seen, and in pathological sections and in culture, it is not easy to find fungi, but fungi can be found if there is a black spot.
