Description
| - V práci jsou sledovány pohybové parametry spermatozoí veslonose (Polyodon spathula) v různých environmentálních podmínkách. (cs)
- Motility parameters of paddlefish (Polyodon spathula) spermatozoa, in different environmental conditions were investigated in this study. Paddlefish spermatozoa demonstrated the following characteristics: 100% of the cells were motile 10 s after activation with velocity 130-160 #m.s-1, then after 2 min velocity decreased to 80-130 #m.s-1; the period of motility was up to 9 minutes. Concentrations between 0.5 to 5 mM of KCl prevented activation of spermatozoa. When transferred into a swimming medium (20 mM tris, pH 8.2 and 1 mg/ml BSA) with 0.5 mM KCl (combined 5 mM of NaCl or MgCl2) 80-100% cells were motile with velocity around 120-150 #m.s-1. MgCl2 significantly improved velocity of sperm motility at 10, 40, 50 and 60 s after activation with stable velocity of sperm around 140 #m.s-1. Very low concentration of 0.125 mM CaCl2 combined with 0.5 mM KCl initiated motility in 20% of sperm while all sperm were activated after 2 minutes with 0.25 mM CaCl2 in similar medium for the full period of swimming
