[Measurement and analysis of hematology and blood chemistry parameters in northern pig-tailed macaques (Macaca leonina)].Dongwuxue Yanjiu. 2013 Apr; 34(2):89-96.DY
The pig-tailed macaque is an important non-human primate experimental animal model that has been widely used in the research of AIDS and other diseases. Pig-tailed macaques include Mentawai macaques (Macaca pagensis), Sunda pig-tailed macaques (M. nemestrina) and northern pig-tailed macaques (M. leonina). Northern pig-tailed macaques inhabit China and surrounding Southeast Asia countries. To our knowledge, no reports have been published regarding the hematology and blood chemistry parameters of northern pig-tailed macaques, which are important for the objective evaluation of experimental results. We measured and analyzed 18 hematology parameters and 13 blood chemistry parameters in juvenile (aged 2-4 years) and adult (aged 5-10 years) northern pig-tailed macaques. We found that red blood cells, hemoglobin and alkaline phosphatase values were lower in female macaques than male macaques in both juvenile and adult groups. White blood cells, lymphocyte, monocytes, platelet distribution width, cholesterol, aspartate aminotransferase and alkaline phosphatase values were higher in juvenile macaques than adult macaques, while creatinine and triglycerides values were lower in juvenile macaques. Mean corpuscular hemoglobin and creatinine values were positively correlated with weight in juvenile groups. In adult groups, mean corpuscular hemoglobin, percentage of granulocyte, hemoglobin and creatinine were also positively correlated with weight, and lymphocyte, percentage of lymphocyte, red cell distribution width, aspartate aminotransferase and cholesterol values were negatively correlated with weight. The results suggest that age, gender and weight of northern pig-tailed macaques affected their hematology and blood chemistry parameters. This hematological and blood chemistry study has great significance in biomedical research and animal models using northern pig-tailed macaque as an experimental animal.
