## Abstract Sixty percent of the dopamine Ξ²βhydroxylase (DBH) (EC 1.14.2.1) activity in rat brain was found to be bound to membrane fractions. The additions of Triton Xβ100 solubilized DBH completely and permitted the estimated of the total enzyme activity. In homogenates the DBH could be detected
There have been no works devoted to the study of the influence of 131 I and maternal 131 I-induced hypothyroidism on the state of the C-cells in the thyroid gland of the developing embryos. A study was made on the effect of a dose of 150 Β΅Ci 131 I (0.5 Gy) leading to hypothyroidism in rats, on 35 mo
