Effects of Exposure to Two Ranges of Temperature on Some Blood Parameters on Sudanese Workers and New Recruit of Air force in Khartoum State

Abstract

This study was conducted at Leader ship Tower workers and New recruit Centre of air force in Khartoum state during March 2015. The aim of this study is to investigate the effects of exposure of two different ranges of temperature on some blood parameters on Sudanese workers and New recruit of air force in Khartoum state. Eighty blood sample were taken from healthy males, 40 blood sample from Leader ship Tower workers (group 1) aged between (18-55) year whom were exposed to a temperaturemeasured by thermometer (accuweather) range between (30-320C) for 6 hours, and 40blood sample fromNew recruit Centre of Air Force (group 2) agedbetween (15-47)yearwhom were exposed to a temperature range between (45-470C) for 6 hours. Three ml of blood were collected from each participant and poured into EDTA containers and taken to laboratory to be analyzed by Mindray BC-3000 Plus.The CBC parameters showed significant variation between two group,Group2 showeda significant decrease RBCs count (4.71+0.47)×1012⁄L than group1 ( 6.04+1.54)×1012⁄L, Group 2 showed a significant decrease in HGB concentration (13.18+1.11)g⁄dLthan group 1(16.76+4.25)g⁄dL ,also group 2 showed a significant decrease in HCT% (53.48+13.81) than group1 (41.49+3.46) . WBCs countshowed asignificant increase in group2 (6.58+1.34)×109⁄L than group1(5.86+1.87)×109⁄L . MCV, MCH , MCHC ,RDW-CV, RDW-SD, Absolute Gran , absolute Lymph , absoluteMid count, Gran% Lymph% ,Mid%, PLT, MPV and PDW did notshow any significant variations between two groups.
