找了一篇感兴趣的翻译了一下，但水平有限，希望各位老师帮我改改，尤其是红字标出的地方，不知道理解得对不对？

Frequent hand washing may result in skin damage and increase the number of microorganisms that colonize the skin. The purpose of this study was to evaluate changes in total flora of healthy and damaged hands that were caused by the use of gloves, soap, and antiseptics. Samples were collected from the healthy and damaged hands of 30 health care professionals before and after washing with water and nonmedicated soap for the technique of sterile polyethylene bag. Fifteen additional volunteers (technicians and students) were asked to wash their hands 20 times with water and soap; those with complaints of irritation were evaluated separately. Damaged or healthy hands did not present statistically significant differences (P > .05) in terms of qualitative analysis of epidemiologically important microorganisms; however, washing with water and soap was effective only for healthy hands. In short, the water and soap washing of damaged hands was not effective in reducing their contamination.

洗手：皮肤菌群的改变
频繁的洗手将导致皮肤损伤，使皮肤定植菌数量增加。本实验的目的在于评估由于使用手套、肥皂和消毒剂引起损伤的手与健康手之间整个菌群的变化。 样本采自30位专业护理人员的损伤手和健康手。分别在洗手前和以水和非药皂洗手后采样，洗手要求达到可操作无菌聚乙烯包的标准。另外15位志愿者（技术员和学生）被要求用水和肥皂洗手20次；分别评估主诉感到手刺激受试者。对流行病学的重要微生物进行定性分析，损伤或健康的手之间没有统计学的显著性差异（P>.05）；然而，水和肥皂洗手只对健康手有效。简言之，已损伤的手用水和肥皂清洗并不能降低手的污染。
