Electrophysiological and behavioral studies were performed in rats to analyze the gustatory effects of alcohols, such as methanol, ethanol, ethylene glycol, 1-propanol, 2-propanol, propylene glycol, 1,3-propandiol, and glycerin. When the whole bundle responses to each of the alcohols at 1.0 M were recorded from the chorda tympani (CT) and glossopharyngeal nerve (Gl), the alcohols with two or th...

To clarify the mechanism by which potassium (KCl) protects against the blood pressure rising action of sodium (NaCl), we studied the effects of KCl loading in patients with idiopathic hypertension who, after a period of NaCl restriction, partook of a high NaCl diet. Eleven patients who had taken the KCl supplement (96 mEq/day) during the high NaCl period showed lesser mean blood pressure (MAP) ...

We examined body fluid regulation by weanling (21-25 days) and adult (>60 days) male rats that were offspring of dams fed chow containing either 0.1, 1, or 3% NaCl throughout gestation and lactation. Weanling rats were maintained on the test diets until postnatal day 30 and on standard 1% NaCl chow thereafter. Ad libitum water intake by weanlings was highest in those fed 3% NaCl and lowest in t...

In mice, behavioral acceptance of the bitter compound sucrose octaacetate (SOA) depends on allelic variation of a single gene, Soa. The SW.B6-Soa(b)congenic mouse strain has the genetic background of an "SOA taster" SWR/J strain and an Soa-containing donor chromosome fragment from an "SOA nontaster" C57BL/6J strain. Using microsatellite markers polymorphic between the two parental strains, we d...

An anticoagulant has been purified from the body fluid of Ascaris suum by sequential passage through Sephadex G-50, CM-cellulose and Sephadex G-25 columns then treated with 2 M NaCl, passaged through a Sephadex G-25 column, separated from the phosphate buffer by precipitation of the latter with the CaCl2, then passaged through a Sephadex G-10 column in water. In the body fluid of the worm, the ...

This study was carried out to study the effect of trace metal addition for hydrogen production The results show that this bacterial need a selected nutrient with selected concentration. The optimum parameters for cultivation were at initial pH of 7.0 and temperature of 30°C. Trace metal addition to the new medium showed that only iron enhanced the H2 yield. The results showed that 25 mgL FeSO4⋅...
