Studies on the Antigenic Structure of Some Mammalian Spermatozoa
1. A method has been described for separation of heads and tails of mammalian spermatozoa. 2. By means of absorption technique applied to homologous spermatozoal sera, head-specific and tail-specific antigens could be demonstrated. Both are heat-labile. 3. A heat-stable antigen was found to be common to both heads and tails. This substance is species-specific. 4. Antibodies against the head- an...
متن کاملStudy of Bull Spermatozoa
The electron microscope has been used to determine the characteristic dimensions and the distribution of the dry mass in bull spermatozoa. The most important result is that all characteristic data are occurring in logarithmic distributions. Furthermore, no correlation between such parameters as head weight and tail weight or head length and tail length was found. The occurrence in logarithmic d...
متن کاملStudies on the distribution of antigenic sites on the surface of rabbit spermatozoa
Antibodies to rabbit spermatozoa isolated from immunized virgin female rabbits were conjugated to hemocyanin and have been used to determine the pattern of antigenic sites over the surface of rabbit spermatozoa under a variety of conditions. When the spermatozoa are incubated with antibody at 0 degrees C, labeling is almost entirely restricted to the postacrosomal sheath. Incubation at room tem...
متن کاملThe Morphology of Bull Spermatozoa
It has been known since the nineteenth century that the microscopical structure of living cells may be modified by fixation and by post-mortem or sub-mortem changes (Hardy, 1899), but inadequate attention seems to have been paid to factors which may injure spermatozoa before fixation and microscopical examination. One such factor is the effect of sudden cooling. If semen is exposed to a sudden ...
متن کاملRelationship between acrosin activity of human spermatozoa and oxidative stress.
AIM To study the association between seminal oxidative stress and human sperm acrosin activity. METHODS It is a prospective study consisting of 30 infertile men and 12 fertile normozoospermic volunteers. A full history, clinical examination and scrotal ultrasound were done to exclude other related factors such as smoking and varicocele. Presence of white blood cells (WBCs) in semen samples wa...
