EFFECT OF LONG TERM VOYAGE ON BLOOD CELL COMPONENT AND RHEOLOGY OF SAILORS IN NAVAL SHIP AND NUCLEAR-POWERED SUBMARINE

Objective:To study the features of blood cell component and blood rheology of sailors in naval ship and nuclear-powered submarine after long term voyage and their significance in health. Methods:The subjects were divided into three groups:naval ship,submarine(nuclear - powered)and control. Results:(1)Erythrocyte series:HGB and HCT in naval ship group increased by 11.63%(P<0.05) and 40.55% (P<0.05) respectively after voyage ;RBC, HGB, MCV and HCT in submarine group increased by 24.69% (P<0.05),19.96% (P<0.01),17.41% (P<0.05) and 33.44% (P<0.05) respectively after voyage.(2) Granulocyte series:WBC and GRAN in naval ship group increased by 59.64% and 59.71% (P<0.05) respectively,whereas LYMF decreased by 21.61% (P<0.05); on the contrary,WBC and GRAN in submarine group decresed by 35.01% and 33.24% (P<0.05) respectively, LYMF increased by 72.57% (P<0.05) .(3)Megakaryocyte series:PLT and PCT in submarine group after voyage decreased by 46.18% and 30.30% (P<0.05) respectively,whereas LPCR increased by 46.13% (P<0.05). (4)Blood rheology:Whole blood viscosity in naval ship increased by 46.03% (P<0.05)and erythrocyte electrophoreticc time decreased by 31.2% (P<0.05); whole blood and plasma viscosity in submarine group increased by 39.36%, 15.33% (P<0.05) respectively, whereas platelet aggregating function decreased by 22.17% (P<0.05).Conclusion:Long term voyage in both naval ship and submarine may markedly affect the blood cell components and rheology of sailors with various features.
