Abstract

The present study examined the changes in the fragility of camel and donkey erythrocytes caused by variations in temperature, pH and blood storage. Although the fragility did not differ between sexes in both species, camel erythrocytes were more osmotically resistant than donkey erythrocytes. At a constant pH of 7.4, the fragility decreased in the camel but increased in the donkey at lowered temperatures. However, at a constant temperature of 28 ºC, the fragility of camel and donkey erythrocytes increased in an acidic solution and decreased in an alkaline solution. Additionally, blood storage for 24 hours at 4 ºC increased the fragility of camel erythrocytes, but not donkey erythrocytes. However, the erythrocyte fragility increased in both species after 48 or 72 hours of blood storage at 4 ºC. In conclusion, our results suggest that variation in the temperature and pH of the erythrocyte environment and duration of blood storage may each play a significant role in the osmotic behaviour of camel and donkey erythrocytes.
