Effect of low and high temperatures on the total LDH activities and electrophoretic patterns of LDH isozymes in the liver and heart of frog, Bombina orientalis were investigated. Total LDH activities in the liver and heart of low (0 ℃ ) and high (33 ℃ )temperature groups were increased in comparison to those of control (20 ℃ ), while LDH activity of low temperature group was greater than that of high temperature group. There were 6 LDH isozyme fractions in the liver and heart at low temperature exposure. When frogs were exposed to high temperature, 6 LDH bands were fractionated in the liver and 5 LDH fractions appeared in the heart. The percentages of liver and heart LDH isozymes at low and high temperatures showed decrease of LDH₁, and increase of LDH_5 in comparison to those of control.
