Studies on Dermatoses Caused by Crops Cultivation and its Prevention

黄秋葵农民职业性皮肤病流行病学调查通过两年多的实地调查，发现黄秋葵种植引起的皮肤病发病率较高（46.3-53.9%），如果工人在没有有效防护手套和衣服的情况下从事工作，则几乎所有人都被认为患有秋葵种植后的皮肤病。16斑贴试验结果显示，有13.6%的人对黄秋葵成分有反应，黄秋葵工作人员的阳性率较高（15.7%）比其他（6.9%）。通过豚鼠实验研究，黄秋葵的主要刺激性反应较强，但过敏性和光毒性反应较弱。黄秋葵的皮肤病机制估计包括以下三个影响：（1）由于直接接触大量黄秋葵而引起的机械反应，（2）对黄秋葵成分的初级刺激反应，（3）对黄秋葵成分的过敏反应，并对黄秋葵皮肤病的有效预防措施进行了探讨。

Epidemiological surveys on occupational dermatoses in farmers growing okra (Hibiscus esculentus L.) and related experimental studies were undertaken.From the field survey over a period of two years, the incidence rates of dermatoses suffering from okra growing were considerably high (46.3-53.9%), and if workers are engaged in the work without effective protective gloves and clothes, nearly all persons are assumed to be suffered from dermatoses following okra farming.Among 118 subjects tested, 16(13.6%) were reacted with okra components by patch testing and okra workers showed relatively higher positive rate (15.7%) than the others (6.9%).By experimental studies using guinea pigs, the components of okra indicated relatively high potency of primary irritating reactions, but not the allergic and phototoxic reaction.Based on those data with epidemiological observations, the mechanism of dermatoses due to okra working were estimated to be consist of the following three effects; (1) mechanical reactions caused by direct contact to a large quality of okra, (2) primary irritating reactions to okra components, and (3) allergic reaction with okra components.Some proposals for effective preventive procedures against okra dermatoses were also examined and discussed.
