缫丝厂工人职业性皮肤病及其防治——宝鸡丝厂调查报告

本文报告了调查陕西宝鸡丝厂工人职业性皮肤病的发病情况,主要是立缫车间工人手部的急慢性皮炎。作者认为其发病原因主要是于长时间频繁地接触热的偏硷性缫丝水和水中所含的某些有机物质或霉菌的分解产物所引起的炎性反应。针对这一原因,作者提出了应用氧化锌软膏防水,明矾水和滑石粉脱水,吸水,水杨酸软膏防治漫性皮炎等防治方法,取得了一定效果。此外,作者还测定了发病工人的血清微量元素、宏量元素和维生素A.E值,发现发病工人的血清中铜,铜兰蛋白、钙、镁及维生素A.E值均有所降低,铁值增高,锌值无改变,其原因尚有待进一步研究,适当注意膳食中对此等物质的补充,可能是有益的。

Observations on Chromosome of Newborns(report of 63 cases)

A series of 63 cases of neonatal umbilical blood chromosomal karyotypes were observed during the period of April to May, 1980. The aim of thiswork is to find the spontaneous chromosome aberrations occurring in thepopulation of Xian. For each case, observations of 20 karyotypes of metaphase mitosis oflymphocyte were made, 4 karyotype pictures were drawn. More than 1260karyotypes were observed. In observing 1260 karyotypes, six abnormal karyotypes were found. Wedetected 2 chromatid break, one acentric fragment, one chromosome break,one chromosome gap. The frequency of the karyotype aberrations we obse-rved was 0. 635%.It is near to the value 0. 59% given by ARH P et al. All themothers of these newborns had never suffered from the virus diseases, tookmedicine and contacted other chemical agents during their pregnancy. Wehave not discovered any inducing factors from their case history. So weconsidered this value (0. 635%) of chromosome aberration may be used as abackground of reference material by chromosome analysis in the southernsuburbs of xian.
