The hypotonic fragility of some fish erythrocytes

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Osmotic fragilities of red blood cells of three freshwater fish species,Ophicephalus punctatus (Bloch),O. striatus (Bloch), andClarias batrachus (L.) were studied under standard conditions in hypotonic solutions of sodium chloride. The fragility curves of the fishes were found to be of normal sigmoid type similar to those of marine fishes and mammalian erythrocytes. The differences between the mean corpuscular fragility (MCF) values among the species investigated were found to be statistically significant, while the standard deviations at H50 (50% haemolysis) showed that the MCF values remained consistent with in the species.

The increment haemolysis curves for the above three species were found to be of monophasic type which showed uniform population of red blood cells.
