Última Structural Modification of the Black Bengal Buck (Capra hircus) Acrosome During Post-testicular Maturation of Spermatozoa International Journal of Morphology Datta,Uttam; Bandopadhyay,Soumendra Kumar; Hembram,Manik Lal. The present study was conducted to measure various biometric parameters of intact/normal acrosomes (AC) collected respectively from caput, corpus and cauda epididymis and vas deferens of Black Bengal buck. Giemsa stained acrosomes were measured after camera lucida drawings. Observations revealed dimensional characters of the acrosomal cap diminished gradually and significantly (p<0.01, p<0.05) during spermatozoa maturation phases in the different regions of the excurrent duct. Shape and size of the AC were also found to be influenced significantly (p<0.01, p<0.05) by the age and body weight of the animals. The structural modification along with decrease in the morphology of the AC reflected one of the maturational indexes of the male gametes in...

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 ancestral biomolecules including some of the...

Ano: 2010 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-95022010000100025 Morphological Study of the Cytoplasmic Droplets as an Index of Sperm Maturation in Black Bengal Buck (Capra hircus) International Journal of Morphology Datta,Uttam; Bandopadhyay,Soumendra Kumar; Hembram,Manik Lal. Location of the cytoplasmic droplets (CD) and their dimensions varied significantly (p<0.01) when sperm cells traverse through the regions of caput, corpus and cauda epididymis and vasdeferens respectively. The gradual diminution in the morphology of CD between the epididymal regions were related significantly (p<0.01, p<0.05). Caudal shift of the CD, along with regression in size and finally their exclusion from the sperm cells reflected one of the most important events in the maturation process of male gametes in Black Bengal buck.
