Title

Study of thyroid hormones (T3 & T4) changes and their relation with histopathology of thyroid glands in water buffalo in Ahvaz, IRAN

Pages

  419-424

Abstract

 BACKGROUND: Thyroid hormones have an important role in regulation of metabolism of protein and energy metabolism in animals, particularly in ruminents. OBJECTIVES: In this study the histopathology of Thyroid glands and hormonal changes of T3 and T4 in water buffalo in Ahvaz, Iran was investigated. METHODS: The Thyroid gland tissues and blood samples were collected from 89 slaughtered buffaloes (66 females, 23 males). Thyroid glands were selected and cut into small pieces for standard histological processing, then the samples were stained with (H & E) procedure and microscopically evaluated. Serum T3 and T4 concentration were measured by Elisa methods. The data were analyzed by the use of T-test. RESULTS: The results showed that) 31% (of Thyroid glands have pathological lesions. The lesions respectively include: focal hyperplasia (31. 5 %), metaplasia (2. 2 %), and chronic thyroiditis (1. 1%). Also, the results showed that (30. 3%) of female and (52. 2 %) of male buffaloes have pathological lesions. We found that T4 concentration of normal buffaloes without Thyroid gland lesions was significantly higher than the other buffaloes (p= 0. 02). CONCLUSIONS: This study showed that there was a positive and significant correlation between T3, T4 concentrations in buffaloes with Thyroid gland lesions (r = 0. 4, p<0. 05), while this correlation was weak between normal buffaloes (r = 0. 1, p>0. 05).
