Abstract
Oocytes collected from the ovaries of slaughtered cows were divided into 6 groups and matured in vitro in different media. Group 1: MPM (Modified Parker's) medium sup¬plemented with ECS 20%; Group 2: MPM medium supplemented with ECS 20% and 10 (Xg/ml FSH; Group 3: MPM medium supplemented with ECS 20% and 50 (ig/ml LH; Group 4: TCM-199 (Tissue Culture) medium supplemented with ECS 20%; Group 5: TCM-199 medium supple¬mented with ECS 20% and 10 U-g/ml FSH; Group 6: TCM-199 medium supplemented with ECS 20% and 50 (ig/ml LH. After maturation in 6 different media and fertilization in Tyrode-lactate medium supple¬mented with BSA, heparin and PHE, fertilization rates according to the maturation groups were 23.3% (7/30), 10.0% (3/30), 3.2% (1/31), 0 (0/33), 39.3% (11/28) and 38.7% (12/31), respectively. Although the difference between the second and third groups was not significant statistically, dif¬ferences among all groups were significantly important (p
Özet
Mezbaha materyali inek ovaryumlarindan elde edilen primer oositler 6 gruba ayrıldı ve farklı medyumlarda in vitro olgunlaştırıldı. Grup l:%20 ECS ilaveli MPM (Modifiye Parker) medyumu; Grup 2:%20 ECS ve 10 |ig/ml FSH ilaveli MPM medyumu; Grup 3:%20 ECS ve 50u.g/ml LH ilaveli MPM medyumu;Grup 4:%20ECS ilaveli TCM-199 (Doku Kültür) medyumu; Grup 5: %20 ECS ve 10 ug/ml FSH ilaveli TCM-199 medyumu; Grup 6: %20 ECS ve 50 ug/ml LH ilaveli TCM-199 medyumu.Allı ayrı grupta in vitro olgunlaştırman sığır oositlerinin, BSA, heparin ve PHE ilaveli Ty-rode-laktat medyumunda in vitro fertilizasyonunu takiben gruplara göre sırasıyla %23.3 (7/30), %10.0 (3/30), %3.2 (1/31), 0 (0/33), %39.3 (11/28) ve %38.7 (12/31) fertilizasyon oranları elde edildi, ikinci ve 3. grup arasındaki fark benzer, diğer tüm gruplar arasındaki farklar ise oldukça anlamlı bulundu (pO.001).
