| sex-associated differences in the mitogenic responsiveness of snake blood lymphocytes. | the blastogenic response of male and female snake (psammophis sibilans) peripheral blood lymphocytes to concanavalin a, phytohaemagglutinin, and e. coli lipopolysaccharide was tested for putative sex-associated differences. data obtained suggest that normal female blood lymphocytes respond relatively vigorous in comparison to male cells or cells taken from gravid female snakes. the data are discussed in terms of possible correlations with the normal status of the animal. | 1989 | 2792500 |
