Abstract

Various Asian countries including china, Thailand, India, Malaysia Korea and Japan commonly used mosquito coils as mosquito repellent. Mosquito coils are slow-burning product which release smoke containing one or more insecticides; it burns for several hours in confine places in order to provide protection to humans against malaria, which spread due to mosquitoes. Present study was intended to examine the toxic impacts of inhaling mosquito coil smoke on male rabbits. Mosquito coils are widely used to kill mosquitoes. A total of forty rabbits were used in this study. These rabbits were divided into two major groups i.e., Control Group and Experimental Group. Experimental group was further divided into 3 sub-groups i.e., E1, E2 and E3.Each group contain 10 rabbits as shown in figure 2.1. Control Group was not exposed to mosquito coil smoke while Experimental groups were exposed to mosquito coil smoke for 3 hours/day. Exposure time remain the same but exposure days vary with each Experimental group i.e., E1 was exposed for 5 days, E2 was exposed for 10 days and E3 was exposed for 15 days. After the completion of exposure day’s blood was collected from the ear pinna of rabbits for the analysis of Red Blood Cells, White Blood Cells and Platelets. Blood samples were analyzed by using Hematology Analyzer. Effect of mosquito coil smoke on weight of rabbits was also observed and morphological changes due to mosquito coil smoke was also evaluated. Results were analyzed by comparing the data of Experimental groups with Control group. According to results a significant decrease was observed in weight of Group E3 rabbits. Results also demonstrated that with the increase of exposure day’s number of White Blood Cells and Platelets were also increased while the numbers of Red Blood Cells become decreased.
