Daily water metabolism of 21 patients was studied for 3 days after intracardiac surgery and whole-body perfusion. The average obligatory water losses of these patients were approximatelv 500, 750, and 750 ml. per 1\I3 of body surface per day on the first, second, and third postoperative day, respectively. A simple system, which combines knowledge of the estimated postoperative water requirement...

The effects of chrysotile, water-leached chrysotile, and silica on microsomal metabolism of benzo(a)pyrene in vitro were studied. Examination of benzo(a)pyrene metabolites generated by 3-methylcholanthrene-pretreated rat liver microsomes, in the presence of chrysotile fibers, revealed a reduction in the overall metabolism of the hydrocarbon. Thus, chrysotile appeared to modify the activities of...

The modulation of primary nitrogen metabolism by water deficit through ABA-dependent and ABA-independent pathways was investigated in the model legume Medicago truncatula. Growth and glutamate metabolism were followed in young seedlings growing for short periods in darkness and submitted to a moderate water deficit (simulated by polyethylene glycol; PEG) or treated with ABA. Water deficit induc...

The importance of vitamin Bs in water metabolism has been studied extensively. Stebbins (1) demonstrated an impaired water metabolism in animals deprived of vitamin Be. Lepkovsky and colleagues (2) suggested that derangement of water metabolism may be involved in the occurrence of fits in vitamin B&-deficient rats. Guggenheim (3) observed that rats in a state of vitamin Be deficiency show a del...

Disorders of water and sodium homeostasis are very common problems encountered in clinical medicine. Disorders of water metabolism are divided into hyperosmolar and hypoosmolar states, with hyperosmolar disorders characterized by a deficit of body water in relation to body solute and hypoosmolar disorders characterized by an excess of body water in relation to total body solute. This article br...

Radix Astragali (RA) with slight sweet and warm property is a significant "qi tonifying" herb; it is indicated for the syndrome of dampness stagnancy due to spleen deficiency (DSSD). The purpose of this research was to explore effects of RA and its split components on gene expression profiles related to water metabolism in rats with the DSSD syndrome for identifying components representing prop...
