Effect Of Two-Stroke Auto Rickshaw Smoke Solution On Wound Healing In Mice - 2009
The use of 3-wheel auto-rickshaws powered by a 2-stroke engine is widespread in south Asia; exhaust from these vehicles may cause different types of toxicities resulting in different pathologies. The aim of this study was to explore the association between exposure to 2-stroke auto-rickshaw smoke solution (2SARSS) and wound healing. The in vivo model of wound healing was customized to evaluate different stages of wound healing. A total of 56 mice were used of aged 4-5 weeks. After anesthetizing and hair removing from dorsum side of mice a wound of 3mm diameter was generated with the help of a sterile wound puncture. Smoke was collected in the lOOml distilled water from six 2-stroke rickshaws and then these solutions were filtered by syringe filters. 10% ointment of all the samples was prepared in Petroleum Jelly and applied to the experimental group, petroleum jelly to positive control group, no treatment was applied to negative control. Macroscopic evaluation was done by using high resolution camera photographs and measurement of wound by vernier caliper on alternate days. At the end of the study (day 12) histological evaluation was done when the control group wounds were healed. Histological examination revealed a significant delay in the outcome of re-epithelialization, dermal matrix regeneration, and maturation of collagen bundles among all 2SARSS-exposed wounds. Delayed activation of neovascularization was seen in the 2SARSS-treated groups at day 12 post-wounding. The Abbot curve, angular spectrum, and several other 3D surface parameters of reverse wound topographies revealed a highly significant reduction (p
