title: [The activation of specific type-III glucocorticoid receptors by pyrazolone series preparations].
abstract: Experiments were conducted on intact and adrenalectomized male Wistar rats (weighing 180-200 g) with labelled corticosterone of high specific activity to study the effect of analgin and aminopyrine on the level of type-III glucocorticoid receptors in the liver. Analgin and aminopyrine in doses of 10(-2) and 10(-3) increase the specific binding of labelled corticosterone by type-III glucocorticoid receptors of the hepatic cytosol and by blood plasma transcortin in modelled experiments. The effect of the agents depends on the dose. Intravenous administration of 140 mg/100 g of analgin to intact rats and intraperitoneal injection of an equal dose of analgin to adrenalectomized rats also increases the specific binding of labelled corticosterone by type-III glucocorticoid receptors of the hepatic cytosol. The importance of the revealed effect of agents of the pyrazolone series in stress regulation is discussed.
