Haemolymph protein profile of the edible oyster, Crassostrea madrasensis (Preston) exposed to different salinities

چکیده
The haemolymph total protein concentration and protein profile of C madrasensis exposed to different salinities were studied. The animals were maintained at salinities 6 ,12,24 and 36 ppt for one month. The serum total protein concentration showed significant reduction at 6 and 36 ppt. The haemolymph protein profile obtained by SDS-PAGE also varied with difference in salinities. There were four bands with molecular weight 86,74,31 and 26 kDa in all the four groups. The intensity of bands was higher in groups maintained at 12 and 24 ppt compared to other groups. The haemolymph of animals maintained at 6 ppt also showed three additional bands of 60, 52 and 13 kDa that were feebly expressed.

The nervous and immune systems of invertebrates can exchange information through neuropeptides. Furthermore, some opioid peptides can function as endogenous immune system messengers and participate in the regulation of the immune responses. The present study was designed to investigate the effects of leucine-enkephalin (L-ENK) on the activity of catalase (CAT) and hydrogen peroxide (H(2)O(2)) c...
