[Changes in the total protein, cholesterol and blood sugar levels in thyroidectomized pigs].

Parallel investigations were carried out of the total thyroxine (T-4), the thyreobinding globulin (TBG), T-3 and FT-4 index, the level of total protein, blood sugar, and cholesterol in thyroid ectomised pigs within the 4th hour and the 40th day following extirpation. Direct correlation was established between the changes in the level of T-4 and the level of blood sugar and total cholesterol at negligible changes in the level of the total protein. After the 4th hour the T-4 level dropped approximately by 45 per cent at the simultaneous decrease in the blood sugar by about 90 per cent.
