The normal physiological values of Korean mongrel dogs were studied, comparing them with foreign references, on the basis of control physiological data measured on 110 cases out of the dogs submitted to the experiments in our department. The hemodynamic measurements varied widely between the both limits of reported normal control data, with the mean value of heart rate 140.4+-26.6/min., and both the systolic and diastolic arterial blood pressures 137.2+-31.7mmHg and 104.7+-14.4 mmHg, as well as the venous pressure of 9.11+- 2.18 cm.H2O. Hematologically, the number of red blood cells 4,571,000+-767,000 per cu.mm., the amount of hemoglobin 11.57+-3.74 gm/dl and the hematocrit 37.3+-7.2 per cent, were equally the values a little lower than the reported normal means. However, the white blood cells were within the reported normal limits both in number, 10,384+-4,877 per cu. mm and their differential counts with slightly broader ranges of variation. The platelet count was 149,800+-47,000 per cu. mm and was also far below the normal, while the coagulation time 9.03+-2.69 min. and the prothrombin time 13.17+-6.52 sec were within normal limits, though a little prolonged. The serum electrolytes, Na 146.6+-10.44mEq/L.,K 4.46+-0. 84mEq/L., CI 118.3+-7.88mEq/L. and Ca 11.45+-5.62mg./dl, and the blood glucose level of 94.9+-31.79mg./dl were essentially not different from the reported normal values. The serum proteins, total protein 7.15+-1.41gm/dl., albumin 4.09+-0.77gm./dl. and globulin 3.18+-0.88gm/dl. were included near the higher limits of the reported normal levels. The thymol turbidity 0.1-3.04 units were normal in 10 cases, and the cephaline flocculation was within normal range except 2 cases out of 26 dogs, showing two positive in 24 hours. And the nitrogen series, NPN 34.61+-10.29mg/dl. and BUN 12.77+-6.37mg./dl. were normal. It may be concluded that from the point of view of hereby measured physiological data compared with the foreign references, the Korean mongrel dogs have a compatible laboratory data with only the special regards to their tendency toward anemia in red blood cell series.[KTCS 1969;1:115-132
