1. Selenium dioxide pretreatment prior to liver formation in Japanese ricefish ( Oryzias latipes ) failed to protect against mercuric chloride. The mercuric chloride LC 50 s and 95% confidence limits for selenium pretreated Oryzias latipes and for th

1. Mercuric chloride injections (10 μmol/kg) caused renal nonprotein sulfhydryls (NPSH) to decrease within 3 hr and then increase by 72 hr after injection. 2. Selenium injections (10 μmol/kg) caused renal NPSH increases. 3. The Se-promoted increase

1. The relationship between coelomic injections of mercuric chloride doses and osmoregulatory responses was measured. Response parameters were weight increases and blood osmolarity decreases 72 hr after dose administration. 2. Massive edema and large

1. Following i.p. mercuric chloride injections, the mercury was deposited primarily in the kidneys. 2. Simultaneous selenium injections prevented mercury induced osmoregulatory failure even though selenium strongly promoted the movement of mercury to

1. 1. Cottontail rabbits retain a large portion of intravenously injected urea-N as measured by improved nitrogen balances. 2. 2. This retention cannot be accounted for by trapping in either the kidneys or body fluids. 3. 3. A daily urea-N supplement
