致病性鳞翅目刺蛾幼虫致皮炎及防制研究

Study on dermatitis of pathogenicity lepidoptera euileidae caterpillar and its clinic experiment

目的 探讨致病性鳞翅目刺蛾幼虫形态及所致皮炎患者临床症状 ,为采取早期控制措施提供科学依据。方法 用老熟茶毛虫、桑毛虫触刺豚鼠的腹面皮肤和自愿者上肢或自然染毒 ,动态观察茶毛虫皮炎的病程 ,对豚鼠皮炎病灶作常规病理学观察 ,比较豚鼠、自愿者染毒前、后血象变化。结果 自愿者皮肤被幼虫触刺后 ,表现为红、肿、痛、热 ,烧灼、麻木感 ,继而呈现丘疹、斑丘疹、斑块、风团块 ,部分病例出现周身不适 76 6 4 %,烦燥 32 71 %,腋下淋巴结肿大 1 6 82 %。豚鼠皮疹病理切片见表皮水疱、脓疱改变。染毒后白细胞、嗜酸性粒细胞高于染毒前。结论 鳞翅目刺蛾幼虫具有致病性 ,致病机制为机械刺伤、生物毒性和变态反应。

Objective To study the pathogenicity of lepidoptera eucleidae caterpillar and the clinic symptom of the dermatitis.To provide science thereunder for make control measure early. Methods The guineapigs abdomen and the skin of volunteer was touched directly by mature tea euproctis pseudoconspersa strand;mulberry tussock moth on their upper limb or nature catch poison.The pathogenic cource was observed continuouesly on human dermatitis caused by tea euproctis pseudoconspersa strand,mulberry tussock moth.Pathological local lesion of guineapigs was cut off on time,and was observed with routine histology.The white blood cell WBC and addicted acid granule cell changes were compared before and after poison.Results There were red,turgescence,pain,heat,burning pain,tickle,numbness and papule,macule,maculepapule,urtica,plaque on the local symptom.There was the whole reaction in some cases 76.64%,fantod 32.71%,oxter lymph knot turgescence 16.82%.There were epidermis bulla,vesicle and pustule on routine cut section of lesion of guineapigs.WBC and eosinophil (EOS) were higher after poison than before.Conclusion The eucleidae caterpillar have pathogenicity.Pathogenic mechanism in human dermatitis is machinal damage,poisonous reaction and allergy.
