Hemoglobin, hematology, intraerythrocytic phosphates and whole blood Bohr effect from lotic and lentic Hypostomus regani populations (São Paulo-Brasil)

Abstract

1. 1. Hemoglobin electrophoretic pattern, whole blood Bohr effect, intraerythrocytic phosphates and some hematological parameters were determined and compared between lotic and lentic Hypostomus regani specimens. 2. 2. The electrophoretic patterns of specimens from both kinds of environments showed four anodic fractions. The relative concentration of the fraction I (the most anodal) is significantly different between specimens from lotic and lentic ambients. 3. 3. Both lentic and lotic specimens presented a low Bohr effect: φ = -0.012 to lentic habitat and φ = -0.187 to lotic one. 4. 4. ATP/GTP ratio are higher than 1.0 for lotic environment specimens and lower than 1.0 for lentic ones. © 1985.
