    Streszczenie angielskie: Thyroxine is known to play an important role during the developmental process of amphibians. The present work is designed on the hypothesis that a functional relationship exists between the thyroid gland and digestive physiology in the adult toad. Three doese of thyroxine (25 ćg/100 g; 50 ćg/100 g; 100 ćg/100 ćg body weight) were orally administered daily to the adult male toad, Bufo melanostictus and changes in -amylase, pepsin, trypsin, and esterase activities of the different zones of the digestive tract, pancreas and liver were observed. The observations were made on 7, 15, and 30 days of thyroxine treatment. The result shows that the dose of 25 ćg increases the enzyme activities in the gastrointesinal tract, liver and pancreas of 7 days treatment. However, prolonged treatment with all the doses shows little effect on these enzymes. The pattern of changes in the enzymatic activities in the digestive tract of the adult male toads show more advanced compartmentalizaiton than that of fishes. It is also found that site-specific enzyme production is not pronounced in this amphibious vertebrate. It is proposed that a positive functional relationship between thyroxine and digestive enzymes exists in the adult male toad.
