A.I. Yushchenko. On the physiology of the thyroid gland: on the fatty and oxidative enzymes of the gland and the influence of the latter on lipolytic and oxidative processes in the blood. — Archive of Biological Sciences. T. XVth, no. 3-rd and 4-th 1910

The thyroid gland, according to the author, has a strong influence on the lipolytic and oxidative functions of the body. Using for his experiments fresh and dried organs of various animals, the author, on the basis of the action of the extract of these organs on fats, comes to the conclusion that the thyroid gland produces an enzyme that decomposes fats; in quantity and strength of the lipolytic enzyme, it is second only to the pancreas and liver.
