Permeability of the bladder mucosa to thiotepa, adriamycin, and daunomycin in men and rabbits.

The permeability of the bladder mucosa to thiotepa and to the anthraquinonic antibiotics, adriamycin and daunomycin, was investigated both in humans and in experimental animals. Instillations in rabbits were performed either in intact males or in animals with ligated ureters. Absorption of thiotepa was significantly higher than that of the antibiotics both in men and in rabbits. Furthermore, a qualitative difference was observed in rabbits in relation to time and with regard to fixation to vesical tissues. In man, absorption was highest after transurethral surgery. It was also increased in cases with extensive anaplastic tumours or in the presence of acute inflammatory reactions.

[Study of the action of tolbutamide on the hypothalamo-hypophyseal-adrenocortical system in normal and obese subjects].

Changes in plasma cortisol during the tolbutamide test were evaluated in normal subjects and in obese patients with a normal (D = 60,1 plus or minus 8,3) or reduced (D = 23,2 plus or minus 9,5) blood sugar decrease coefficient. Increases were noted in normal subjects (from 14,0 plus or minus plus or minus 2,9 mug/100 ml to 25,5 plus or minus 11,5 mug/100 ml) or in obese patients with normal D (from 15,7 plus or minus 5,1 mug/100 ml to 25,9 plus or minus 9,2 mug/100 ml), while no significant variations were observed in patients with depressed D. Though a direct corticosteroidogenetic effect and/or interference with liver metabolisation of cortisol (and increased clearance) cannot be excluded, the data suggest that increased blood cortisol following tolbutamide is secondary to the lowering blood sugar action of the drug.
