Indigenous method of preparation of dried anatomical specimens

Abstract

Formalin fixed anatomical specimens are traditionally used for teaching in various medical and veterinary colleges. In these specimens the natural shape of the organs is difficult to appreciate. Plastination, though well known for its unique preservation qualities of anatomical specimens, is still more costly. The present study is aimed to develop an indigenous method of air dry preservation for lungs and balloon inflation technique for hollow organs. The lungs were infused with 5% formal saline and immersed in the same for a week and with the help of compressor the natural shape and size was maintained and air dried. The hollow organs were infused with 5% formal saline for a week and with the help of balloons, the natural size and shape was maintained and air dried. The specimens were very economical, can be stored in open space without any preservatives and can be handled comfortably by both students and teachers. It also avoids the ill effects of formalin such as irritation to eyes, nose, respiratory tract and carcinogenicity.
