    Notes: Summary Renin secretion was studied in anesthetized dogs (Pentobarbital), after an injection of 5 mg/kg i.v. clopamide (10 animals) or ethacrynic acid (10 animals). Renin activity in venous renal blood (Boucher's method), renal blood flow (electromagnetic flowmeter), blood pressure, diuresis and natriuresis have been measured simultaneously. Basic renin secretion was 22,4±8,2 ng/g of kidney/min. During the 8 min following the ethacrynic acid injection renin secretion increased to 74,4±41,1 ng/g of kidney/min (p〈0.005). Within the same time it dropped to 11.1±6.8 ng/g of kidney/min (p〈0.005) after clopamide. These variations of renin secretion are related to the diuretic's action on the nephron, and depend on an endorenal mechanism. Ethacrynic acid suppresses the corticopapillary gradient while clopamide does not. We have not found any correlation between renin secretion and either natriuresis (mg/min) or diuresis (ml/min). But there is a connection (r=0.7367) between renin secretion after ethacrynic acid injection and sodium concentration in urine.

    Binding of end product in the fermentation of nucleotides (1973)

    Notes: Flavor enhancing nucleotides may be produced by streptomycetes. Mutants of streptomyces 772 were found to produce, under ordinary fermentation conditions, considerable amounts of 5′-IMP and 5′-XMP, but only traces of 5′-GMP. This was probably due to the feedback inhibition of the end product GMP. It was shown that through suitable fermentation techniques it was possible to overcome this internal control mechanism, leading to increased yields of 5′-GMP.
