Background: We were using a low concentration of formalin(10%) for the preservation of donated bodies. However, it gives a short lifetime of the specimen and they are more proven for fungus growth. We use high concentration formalin (30%) to achieve prior purposes and to observe any changes in the human tissues. The present study aims to compare high and low concentration formalin effect on the body tissues and rate of fungal growth. Methods: The donated bodies were embalmed with high and low concentration formalin in the right femoral artery. Then observation was made over the skin, muscle, nerves, vessels, and solid organs like liver, lung __ampersandsignamp; brain. Results: In high concentration formalin the lifetime of the specimen was more but the quality and fungal growth were the same as low concentration formalin; the quality of the cadaver was poor compared to low concentration formalin. Conclusion: The use of low concentration formalin results in good quality cadaver over the high concentration formalin.
