Abstract

Red blood cell (RBC) count, RBC size, hematocrit, cell and blood hemoglobin concentrations and plasma total solid concentration were measured in 16 lowland (from near sea level up to 2700 m) and 18 highland (3200 up to close to 4500 m) adult toads (Bufo spinulosus). 2. Lowland toads showed higher hematocrit values than highland toads, but their blood hemoglobin concentration and plasma solid concentration were not significantly different. 3. Highland toads had smaller RBC size, higher corpuscular hemoglobin concentration, a trend toward larger RBC count and a considerably smaller body size. These features may contribute to their successful life at high altitude.

摘要

对16只低地（海拔接近海平面至2700米）和18只高地（海拔3200米至接近4500米）成年棘蟾蜍（Bufo spinulosus）测量了红细胞（RBC）计数、红细胞大小、血细胞比容、细胞和血液血红蛋白浓度以及血浆总固体浓度。2. 低地蟾蜍的血细胞比容值高于高地蟾蜍，但其血液血红蛋白浓度和血浆固体浓度无显著差异。3. 高地蟾蜍的红细胞尺寸较小、红细胞血红蛋白浓度较高、红细胞计数有增加趋势且体型明显较小。这些特征可能有助于它们在高海拔地区成功生存。
