Abstract:
Objective To explore the changes of sweat ducts in nail fold microcirculation among population migrating from plain to plateau.Methods The nail fold microcirculations of123male youngers migrating from plain to plateau were examined with microcirculation microscope during the6-day living at altitude of2800m,6-day,2-month,and6-12-month living at alti-tude of4700m respectively,using the intravital microscopy and indexes of microcirculation recommended by TIAN Niu.Re -sults The increasing rates of the number of sweat ducts increased significantly with the altitudes and the prolongation of living period among population migrating from plain to plateau.The total weighted score of nail fold microcirculation increased,the blood flow velocity slowed down,the red blood cell aggregation became heavier,the diameter of the afferened limb,the output branch and opexes changed significantly with the increase of the number of sweat ducts.Conclusion The changes of sweat ducts had a hand in these mens physiological adaptation and mechanism of acclimation in high altitude,also maintained close links and effect with the functional change and some pathology of nail fold microcirculation.
