Study of ionic parameters (Na, Ca, Mg, Cl, K) in the bloodof Crocodylus Palustris in Iran

Crocodylus Palustris is the native species of Iran (Sistan–Baluchestan province) on which no research in the field of physiology has been conducted to date. In the present research, experiments were performed on the unic parameters (Na, K, Ca, Cl, Mg) of the Crocodylus Palustris blood residing in Sistan–Baluchestan province. For this reason, 12 numbers of crocodiles which were in captivity under similar experimental condiyions were selected and their blood samples collected.During the research, the experimental conditions involving the residence, protection, temperature, made of nutrition, and the procedure of blood sampling of the crocodiles were controlled and like wise similar. All the crocodiles were subjected to bioevaluation and wean while their weight, length and other related characteristics were recorded.Results showed that among the ions calculated, sodium ion with a variation coefficient of o.4 percent and magnesium ion with a variation coefficient of 7.7 percent respectively, have a very small variance and a large variance which are independent of body weight. Calcium ion did not show significant correlate except with chloride ion and has a large and reversed correlation with magnesium ion at the level of one percent. Calcium ion also has a significant and linear correlate with sodium and potassium ions at the level 1 percent. Potassium ion has reversed correlate only with magnesium ion at the level of 1 percent.On another hand, potassium ion has a significant correlate with sodium ion at the level of 1 percent, which is linear. But potassium ion does not show significant correlate only with chloride ion and showed significant and reversed correlate with other characteristics at the level of 1 percent. Chloride ion also displays no significant correlation with sodium ion.
