Stress 가 ( Crassostrea gigas ) 의 LDH isozyme 에 미치는 영향 = The Effects of Stress on Lactate Dehydrogenase Isozyme in Oyster ( Crassostrea gigas )

다국어 초록 (Multilingual Abstract)

Changes in lactate dehydrogenase isozymes in oyster exposed to salinity, pH and temperature stress were investigated by polyacrylamide gel elctrophoresis. LDH isozyme patterns indicated that the number of isozyme bands was changed in some degree in each salt con-centration 12 hours after salinity stress but in great degree 24 and 48 hours after salinity exposure. pH stress affected the number of LDH isozyme bands. 12 and 24 hours after pH exposure it was changed a little bit in each pH, but a lot 48 hours after pH stress. However, temperature stress did not make an impact on the number of LDH isozyme band. Activity of isozyme bands appeared in various patterns depending on different stress. The effect of stress on LDH isozyme was appeared in order that salinity is the most influential factor and pH is the second, and temperature is the last. In conclusion, changes in LDH isozyme seemed to be correlated to the resistance through defence mechanism.
