초록

The in vitro maturation rate of vitrified-thawed canine oocytes was $30.8{\pm}3.4%$. The in vitro maturation rate of vitrified oocytes was lower than that of the control ($52.0{\pm}2.5%$, p<0.05). The in vitro maturation rate of vitrified-thawed oocytes were significantly (p<0.05) lower than those of fresh oocytes. The in vitro maturation and developmental rates of the vitrified-thawed oocytes were $17.5{\pm}2.5%$ and $8.8{\pm}3.4%$, respectively. This results were lower than the control group ($43.6{\pm}3.2%$ vs $20.0{\pm}3.0%$). SOD1 gene expression of 1~2 mm of follicle size were higher than those of above 6 mm follicle size. SOD2 gene expression of 1~2 mm of follicle size were significantly higher than those of above 6 mm follicle size (p<0.01). The expression pattern of SOD1, 2 was constantly expressed in both groups but strongly expressed in follicles (1~2 mm) group when compared to the above 6 mm follicles. SOD gene expression between groups the fresh and vitrified oocytes groups were significant differences in rates. However, RGS gene expression between groups the fresh and vitrified oocytes groups were no significant differences in rates.
