Molar sodium lactate, sodium bicarbonate, sodium chloride, glucose insulin, and calcium chloride were used in the treatment of induced hyperkalemia in nephrectomized dogs. The effect of these agents on the electrocardiogram and on potassium partition was studied. Molar sodium lactate appeared to be the agent of choice in the treatment of the hyperkalemic state under these experimental conditions.

Gelation speed is directly proportional to the concentration of calcium. Although the kinetics of gelation are altered by the source of calcium, the final alginate gel strength nor the resistance to calcium diffusion are altered. Calcium chloride reaches a gel strength plateau fastest ( 100 s), followed by calcium lactate ( 500 s) and calcium gluconoate ( 2000 s). Calcium chloride is the best o...

Two experiments were conducted with ruminally fistulated wether lambs to determine the effect of lactic acid addition to a hay diet on rumen lactate metabolism, blood acid-base status and subsequent adaptation to a high concentrate diet. In Exp. 1, lambs were fed mature brome hay (H), H plus 5% (w/w) D,L lactic acid (H5L) or H plus 10% lactic acid (H10L) (three lambs per treatment) for 14 days ...

Background: Food fortification is an effective strategy that has been recommended for improving population calcium inadequate intakes. Increasing concentration of water proposed as a possible to improve intake. The objective this study was determine the sensory threshold different salts added drinking using survival analysis. Methods</ns4:bol...

BACKGROUND: Dairy cows undergo physiological changes during pregnancy and lactation and cardiovascular system may alter during these periods. OBJECTIVES: Understanding the physiological effects of production periods of dairy cows on heart electrical activities can aid to better monitoring the cardiovascular system in these animals. METHODS: Five multiparous Holstein dairy cows were studied from...

In the study the effect was assessed of sample processing with solutions containing inhibitors of enzymatic browning and tissue softening and sucrose on the quality of minimally processed apples. Ascorbic acid, citric acid, 4-hexylresorcinol, sodium chloride, calcium chloride, sodium lactate, calcium lactate and sucrose were used as inhibitors. The application in apple slice processing of a sol...

There is concern regarding neurotoxicity induced by the use of local anesthetics. A previous study showed that an overload of intracellular calcium is involved in the neurotoxic effect of some anesthetics. T-type calcium channels, which lower the threshold of action potentials, can regulate the influx of calcium ions. We hypothesized that T-type calcium channels are involved in bupivacaine-indu...

Jackson, Donald C., Carlos E. Crocker, and Gordon R. Ultsch. Bone and shell contribution to lactic acid buffering of submerged turtles Chrysemys picta bellii at 3°C. Am J Physiol Regulatory Integrative Comp Physiol 278: R1564– R1571, 2000.—To evaluate shell and bone buffering of lactic acid during acidosis at 3°C, turtles were submerged in anoxic or aerated water and tested at intervals for blo...
