RESUMO
The urinary excretion of andro- and glucocorticoidogenesis metabolites was studied in 60 patients with gastric cancer (stages II-III and IV). The androgenous activity showed a significant decrease that was manifested in a reduced excretion of 17-ketosteroids (17-KS) and their androgenicity index (AI). With advance of the disease stage androsterone/ethiocholanolon ratio reduced and became less than 1 in most patients. In patients with stage II-III gastric cancer there occurred a significant increase of the glucocorticoid function of the adrenals and a decrease in patients with stage IV cancer. Comparison with the androgenous activity revealed both an absolute and a relative androgenic insufficiency in patients with gastric cancer. It is suggested that reduced production of androgens effects favourably the catabolic manifestation of the effect of glucocorticoids. Drug-stimulated increase of the production of androgens in the body of patients with gastric cancer is desired.

Four patients with acute intermittent porphyria (AIP) were treated and followed-up. It was established that in AIP urinary pigments have specific absorption spectra in the visible light range. Clinical manifestation and the severity of the disease course correlated with the amount of excretion of copro- and uroporphyrin and their characteristic spectrum of light absorption. It is concluded that of significance in the AIP pathogenesis is the level of formation of copro- and uroporphyrin isomers which may directly effect the nervous tissue and clinical manifestations of AIP. It is recommended to use plasmapheresis in biohemosorption by means of extracorporeal donor spleen.
