BACKGROUND
Goitre or swelling of thyroid gland is very common in North-East region and is encountered frequently in clinical practice. Goitre is a compensatory hypertrophy of thyroid gland and it has been recognised for centuries even back to the times of Ebers Papyrus (1500 BC) (LE McDonald.) The thyroid is the largest endocrine gland present in all mammals. In some disease conditions, an individual has to undergo a complete thyroidectomy and live on thyroid supplements for life. Is there a possibility of xenograft and xenotransplant? With this view a comparative study of the thyroid gland was under taken in the Dept. of Anatomy, Gauhati Medical College, Guwahati. The main purpose of the study was to see if thyroid gland of human was in any way similar to thyroid gland of other mammals. Xenograft and Xenotransplantation are the latest research studies going on these days. By these techniques, tissues and organs of one species can be transplanted or grafted into another species.
MATERIALS AND METHODS
The study of thyroid gland was conducted in Dept. of Anatomy, Gauhati Medical College. The various species included for studies were of human, pig and goat. They were divided into three groups I, II, and III. The specimen of human was collected from morgue of Gauhati Medical College. The specimen of pig and goat were collected from College of Veterinary Sciences, Gauhati. In all animals, the size, shape, length, breadth, thickness was recorded.
RESULT
The length, breadth, thickness of thyroid gland in group I, II and III were taken with the help of Vernier callipers. Weight was measured with the help of electronic weighing machine. The results were statistically analysed.
DISCUSSION
The findings of this study were compared with the findings of work done by other authors previously.
CONCLUSION
In this study, it was observed that biometrical values were different in all the mammals but morphological characters were almost similar.
