通过对36名输油泵站工人(泵工、加热炉工)检查甲襞微循环,发现微血管管袢的血色、排列、长度和管径均在正常范围之内,与对照组基本一致。但管袢的清晰度差(占56%)、数目减少(小于8条,占97%),异形管袢增多(大于30%,占55.5%),渗出增加(44.4%)以及血液流速缓慢、颗粒流,以上结果与对照组 By examining the microcirculation of nail polish in 36 oil pumping station workers (pump workers and reheat furnace workers), it was found that the color, arrangement, length and diameter of capillaries were within the normal range, which was basically the same as the control group. However, the accuracy of the tube was poor (56%), the number decreased (less than 8, accounting for 97%), the number of deformed tubes increased (more than 30%, accounting for 55.5%), exudation increased (44.4%), and blood flow was slow , Particle flow, the above results with the control group
