摘要
The blood of about three months old Cystophora had an O2 capacity of 36 vol %. RBC was normal, 4.8 × 106/mm3, but Hct and Hb content were very high, 63 % and 26.4 g /100 ml. When calculating the MCV as Hct/RBC × 10 and from the Price-Jones curve the mean values were 131 and 135 μ3. The Cystophora red blood cell was 60% larger and had a 30% higher MCHC than that of humans. The T50 was 24 mm Hg and the mean Bohr effect factor (° log T50/°pH) was -0.66, i.e. somewhat higher than in previously investigated mammalian divers. Relatively high Haldane effect, 8.4 vol % CO2, and buffering capacity (°[HCO-3]/°pH), -36 meq/L, were found in the blood. It is generally concluded that the investigated characteristics of Cystophora blood differ from those of human blood in accordance with its higher Hb content. © 1969.
