| Abstract:
Biochemical analysis of the cytosol fraction isolated from the ovotestis / spermatheca glands of marine mollusc Telescopium telescopium and it’s sperm microtubular structure revealed that relatively similar biomolecules like different enzymes, hormones, minerals and structures of the sperm are also exist in humans. Moreover, antiserum of the cytosol fraction was found to cross-react with the human sperm antigen indicated presence of a common sperm surface antigenicity between these two diversified species. These findings might support and / or hypothesize about the origin and diversification of the vertebrate molecules from its ancestral form (s) from the invertebrates, and basic physiological functions of these... |

| Electrolyte free mediums prepared with soybean lecithin-glycerol,Coenzyme Q10–glycerol and soybean lecithin-Coenzyme Q10-glycerol were inoculated separately into ligated cauda epididymides, equilibrated 2 h at 5 degree centigrade, wrapped with aluminium foils along with testis and freezed at -10 degree centigrade.Spermatozoan characters were evaluated 7 and 21 days after thawing at 38.5 degree centigrade in a water bath for 5 min. Spermatozoan characters were diminished gradually and significantly (P<0.001, P<0.05) between the mediums and observation days. Soybean lecithin-CoenzymeQ10-glycerol effectively protected spermatozoa against cold shock where spermatozoan progressive motility, livability, hypo-osmotic swelling... |
