Abstract
Background: The use of mosquito coils has increased exponentially, especially in the under developed countries. Many researches have been conducted over the past few years to advocate both the possible risks and potential benefits. These coils and the inhalation of their smoke have been proved to cause upper and lower airway tract infections. But still the possible side effects of inhalation of these coil smoke on other organ systems of the body were unclear. Methods: Adult male Wistar rats were divided into two groups each containing eight rats. Group A was control group while group B was allowed to inhale mosquito coil smoke for four week. The experimental group was exposed to MCS for 8 hours / day. Histopathological analysis of testis was carried out. Results: Histopathological studies of rats exposed to MCS revealed changes in parenchyma of testis. Decrease in the height of germinal epithelium and diameter of seminiferous tubules and increase in and vascular congestion was observed. Conclusion: The results of present study suggest that allethrin based mosquito coil smoke has harmful effects on testis
Highlights
Mosquito coils are slow burning devises which emits smoke
Effect of D-Transallethrin on Diameter of Seminiferous tubules: Significant decrease was observed in the value of mean diameter of the seminiferous tubules (p-value= 0.000*) when compared between the control and experimental groups (Table 2)
Marked germinal epithelial cell loss with deranged contour of tubules was observed in histological sections of experimental group
Summary
Mosquito coils are used in under developed countries to control mosquito-borne diseases like malaria, dengue fever, West Nile fever, and yellow fever. Literature review suggested that mosquito coil smoke has toxic effect on various organ like kidney, heart, lungs, and liver [4,5,6]. It induces adverse changes in female and male reproductive system [7,8] This study was designed to study the effect of mosquito coil smoke inhalation on the histology of parenchyma of testis
