Název v původním jazyce

Methyl glycol, methanol and DMSO effects on post-thaw motility, velocities, membrane integrity and mitochondrial function of Brycon orbignyanus and Prochilodus lineatus (Characiformes) sperm

Popis výsledku v původním jazyce

The aim of this study was to use more accurate techniques to investigate the effects of cryoprotectants (CPAs) and extenders on post-thaw sperm quality of Brycon orbignyanus and Prochilodus lineatus. Six freezing media comprising the combination of threeCPAs (DMSO, methanol and methyl glycol) and two extenders (BTS and glucose) were used. Sperm was diluted in each medium, loaded into 0.5-mL straws, frozen in a nitrogen vapor vessel (dry-shipper), and stored in liquid nitrogen at -196 A degrees C. Post-thaw sperm motility rate and velocities (curvilinear = VCL; straight line = VSL; average path = VAP) were evaluated using a computer-assisted sperm analyzer. Membrane integrity and mitochondrial function were determined using fluorochromes. Post-thaw quality was considered high when samples presented the following minimum values: 60 % motile sperm, 140 A mu m/s of VCL, 50 % intact sperm membrane and 50 % mitochondrial function integrity. High post-thaw quality was observed in B. orbignya
