Abstract
The obtained data in the present study can be summarized as follows: 1. Cholinesterase (ChE) activity was reduced in the workers occupationally exposed to insecticides alone more than that in the case of workers occupationally exposed to insecticides alternatively with rodenticides. 2. Acetylcholinesterase (AChE) activity in the evening was reduced after exposure of workers to pesticides in com parison to that of the morning. 3. Protein levels were significantly increased at the 4th month of the spraying season (August) among the workers occupationally exposed to’ insecticides alone, and at the end of the application season (October) in the workers ,. occupationally exposed to insecticides alternatively with rodenticides. 4. Serum glutamic oxalacetic transaminase activity (SGOT) was significantly increased at the 2nd month of the spraying season (June). While, serum pyruvic transaminase , activity (SGPT) was reduced at the 4~ month (August) among the workers occupationally exposed to insecticides alone. Although, (SGOT) was increased at August, yet (SGPT) was reduced at this time among the workers occupa tionally exposed to insecticides alternatively with rodenticides. 5. Serum alkaline phosphatase (AP) activity was significantly increased in June and August among the workers of group I and group 11 respectively. In addition, bilirubin content was significantly increased at the end of the spraying season in both groups. . 6. Serum triglycerides were increased at June, August and at the end of the application season among the workers of group I and at the end of the application season (October) among the workers of group 11. In the mean time, serum B-lipoprotein was significantly increased at the end of the spraying season (October) among the workers of group I only. While, in the 2Qi group, there was no significant difference between the unexposed and exposed groups. 7. Serum total lipid level was increased at the 2nd month , of the spraying season (June) and continued till the end of the spraying season among the workers of group I. While in the case of the workers of group 11, it was increased at the 4th month of the application season (August). In addition, serum cholesterol level was signi ficantly increased at the end of the application season (October) among the workers of group I and group 11. 8. Potassium level was significantly decreased in August and October among the workers of both groups. Also, sodium level was significantly decreased at the 4!h month (August) and at the end of the spraying season (October) among the workers of group I. While it was significantly decreased at the end of the spraying season (October) among the workers of group 11. 9~ Chloride level was significantly decreased at the 4th month (August) and at the end of the application season (October) among the workers of group I. While, it was significantly decreased at th~ end of the application season (October) only among the workers of group 11. In addition, ther level of copper was significantly increased at the end of the application season (October), while no significant change in copper content was noticed in the group 11. , la. The percentage of lymphocytes count was high in group I and group 11 at the begining of the spraying season (April). The maximum increase was noticed at the 4tb month of the spraying season (August) in group 11 and at the end of the application season (October) in group 1. 11. The percentage of neutrophils count of both exposed groups I and 11 were less than the normal count of the unexposed workers. The maximum decrease was noticed at the 4~ month of the application season (August) in group 11 and at the end of the application season (Octo ber) in group I. 12. The percentage of monocytes count of exposed workers group I and group 11 was less than the normal value. The maximum decrease was noticed at the 4th month of the spraying season in both groups I and 11. 13. The percentage of eosinophil count of group I and group 11 was less than the normal count of the unexposed individuals at the zero time of the application season (April). This count was increased gradually up to the normal value’ at the end of the application season. , 14. The percentage of basophil count of both group I and 11 was less than the normal value of the unexposed indivi duals at the zero time of the spraying season (April). This percentage count for both groups I and 11 showed various degrees of variations. 15. Serum glutamic pyruvic transaminase activity (SGPT) was reduced among the workers occupationally exposed to rodenticides alone (Group Ill) during the spraying season. In addition, serum bilirubin content was signi ficantly increased among the workers in group III during the spraying season. 16. Serum glutamic oxalacetic transaminase activity (SGOT) and serum alkaline phosphatase activity (AP) values were not affected among the workers of group Ill. 17. The level of RBCs count was significantly decreased I . among the workers in group III during the application season. While the level of WBCs count was significantly increased. 18. The percentage of lymphocytes count was significantly , increased, while the percentage of neutrophils count was significantly decreased during the application season among the workers exposed to rodenticides alone (group Ill). In addition, no deviation from normal values of monocytes, eosinophils and basophil count were observed among the workers of group Ill. 19. The percentage of haematocrit was significantly decreased among workers of group Ill, while no deviation from the normal values of mean cell volume (MCV) was observed. 20. Bleeding and coagulation time were significantly increa sed during the application season among the workers exposed to ”rodenticides alone (group Ill).
