Abstract:
The present study is an attempt to delineate the effect of various salt administrations on the changes of blood pH and electrolytes, especially the nature of serum calcium, total and ionic, and serum magnesium. Thirty five male rabbits weighing 1.9 to 2. 5kg were used in this experiment. At the end of the three days diet adjustment period, the animals were divided into seven groups; Group I; Control, Group II; Ammonium chloride oral administration, Group III; Oral administration of sodium bicarbonate, Group IV; Potassium chloride intraveneous injection, Group V; Sodium chloride intravenous injection, Group VI; Calcium chloride intravenous injection, and Group VII; Magnesium chloride intravenous injection. The blood pH was determined by the method by Astrup and bicarbonate in serum by the method of Van Slyke and Neill. Sodium and potassium in serum were determined with an EEL flame photometer. Chloride was determined by the method of Schales and Schales and inorganic phosphorous by the method of Fiske and Subbarrow. Serum total calcium and magnesium were determined according to the method of chelometric titration with Eriochrome blue S.E. Serum ionic calcium was determined by the method of Yanagisawa. The results of this study are as follows: 1. The oral administration of ammonium chloride produced a significant decrease in blood pH. The serum concentrations of bicarbonate, magnesium and potassium were steadily decreased, but serum chloride, serum total and ionic calcium concentrations were increased through the experiment. 2. Sodium bicarbonate ingestion increased the concentration of bicarbonate, magnesium and serum ionic calcium markedly and serum ionic calcium slightly. The blood pH was significantly increased but serum chloride concentration was markedly reduced after ingestion of sodium bicarbonate However, serum potassium and inorganic phosphorus concentrations were decreased slightly. 3. The blood pH was dropped in the first two hours of intravenous injection of potassium chloride and tended to rise again significantly. the concentration of sodium and chloride in serum was increased markedly in two hours of injection but reduced after six hours to control level. Serum phosphorus, total and ionic calcium were reduced steadily, but serum concentration of magnesium, potassium and bicarbonate concentrations were slightly increased through the experiment 4. After sodium chloride was given, intravenously, there was a sustained increase in the concentration of serum sodium, potassium, phosphorus and bicarbonate but the blood pH was decreased in the first two hours and significantly elevated through the experiment. The serum concentration of chloride, magnesium, total and ionic calcium was decreased slightly. 5. B100d pH was slightly increased and the concentration of chloride was elevated sharply after injection of calcium chloride intravenously in the first two hours and come to control level in twenty-four hours. Serum sodium concentration was elevated steadily through the experiment. The concentration of total and ionic calcium in serum was elevated after injection but come to control level in twenty four hours of injection. Serum potassium and magnesium concentrations were decreased slightly in the first two hours and increased in four hours of injection. 6. Magnesium chloride intravenous injection produced a decrease in blood pH and serum concentration of bicarbonate in the first few hours and increase after 6 hours of injection. Serum magnesium, and inorganic phosphorus levels were increased after injection but the concentration of inorganic phosphrous was decreased markedly in twenty four hours of injection. Serum concentration of chloride, ionic calcium and potassium wag markedly reduced.
