Long term administration of aldosterone (1) or desoxycorticosterone acetate (DCA) (2) to normal subjects has been shown, in certain instances, to produce continued renal potassium loss but only transient sodium and chloride retention. This adjustment of the renal response to sodium-retaining adrenal steroids has been termed an "escape" (3) from the expected effects of these compounds, and is se...

Nodular hyperplasia or adenomas have been shown to develop in the adrenal glands of certain strains of mice, notably CBA, DBA, BALB, NH, and A, after the removal of their gonads (5, 7, 8, 13, @1). These changes were usually accompanied by the elaboration of either estrogenic or andro genic hormones or both (3, 6). In CE mice, car cinomas developed in 100 per cent of the females and in 97 per ce...

Balances of sodium, potassium, and water were studied in the growing male pig as hypertension developed in response to subcutaneous implantation of deoxycorticosterone acetate (DOCA). Serum sodium, potassium, deoxycorticosterone (DOC), aldosterone, and plasma renin activity (PRA) were determined. These variables were observed in a total of 10 experimental and nine control pigs. All animals were...

We previously demonstrated the preventive effect of sesamin, a lignan from sesame oil, on the development of several experimental models of hypertension. In the present study, we explored the mechanisms underlying the antihypertensive effect of sesamin using the deoxycorticosterone acetate (DOCA)-salt rat hypertensive model. After a 5-week treatment period, aortic superoxide (O2-) production wa...

Extensive evidence reported here and elsewhere indicates a hormonal role for atrial natriuretic factor. In the light of this evidence, it appears that atrial natriuretic hormone is a more appropriate term for these peptides than atrial natriuretic factor. Plasma levels of immunoreactive atrial natriuretic hormone were measured daily in seven pigs before and 1 week after subcutaneous implantatio...

Although nitrate limitation in most natural wetlands results in pseudo-first-order reductions, large site-to-site variations in apparent denitrification rates cannot be easily explained by water quality (e.g., pH, Temp, DOC) or plant productivity. Our microcosm results show increasing nitrate removal efficiencies at higher ratios of total applied plant carbon to nitrate reduced, suggesting that...

The presence of natural organic matter (NOM) strongly impacts drinking water treatment, water quality, and water behavior during distribution. Dissolved organic carbon (DOC) concentrations were determined daily over a 22 month period in river water before and after conventional drinking water treatment using an on-line total organic carbon (TOC) analyzer. Quantitative and qualitative variations...
