생쥐 초기배의 배반포 발달율이 BSA첨가 배양액에 Barodon-FX(equation omitted) 첨가로 증가되지 않았으나 PVP 첨가 배양액에 0.25% 첨가에서는 부화배반포 발달율이 54.7%로 대조구(32.5%)보다 크게 향상 되었다(P ＜0.05). 1∼2% Barodon 첨가는 배발달을 월등히 저하시켰다. Barodon 첨가에 따른 체세포 증식율은 BOEC와 GC의 경우 0.25∼0.5%에서 대조구보다 각각 24∼40%와 17∼22%더 크게 증가되었다(P＜0.05). 그러나 GC와 CC에서는 1%이상 첨가시 세포증식이 크게 억제되었다(P ＜0.05). Barodon의 효과는 체세포간에 큰 차이가 있었다. 소 초기배에서 상실배이상의 배발달율은 BOEC와 GC 공배양조건에서 Barodon 0.5% 첨가에서 대조구보다 크게 향상되었다(P＜0.05). 그러나 다른 처리 수준에서는 배 발달율이 대조구와 차이가 없었다. 결론적으로 Barodon의 세포증식효과는 세포종류에 따라 차이가 많았으며 0.5% 수준의 첨가는 소 초기배의 배반포발달율을 향상시킬 수 있었다.
This experiment was designed to evaluate effects of nonspecific immunostimulator(NIS) Barodon-FX(equation omitted), anionic alkali mineral complex and far-infrared radiation solution on in vivo-produced mouse and in vitro-produced bovine embryos to blastocyst development. Proportion of mouse embryos developing into blastocyst was not greater in BSA- and Barodon-added medium than in BSA-control, but there was signifcantly different(P ＜ 0.05) in hatching and hatched blastocyst development between 0.25% Barodon-and PVP-contained medium(54.7%) than PVP-control(32.5%). BOEC and GC resulted in higher proliferation rate(24∼40% and 17∼22%, respectively) in 0.25∼0.5% Barodon-added medium than in controls, but proliferation of GC and CC greatly decreased in 1∼2% Barodon-added medium. Effect of Barodon on cell proliferation greatly varied among somatic cells. Proportion of early bovine embryos developing into morula and blastocyst was significantly greater(P ＜ 0.05) in 0.5% Barodon-added medium(50% and 63.6%) than in control(31.6% and 27.4%) under co-culture with BOEC and GC, but developmental rate was not different between other Barodon treatments and control. These data indicate that effect of Barodon on cell proliferation significantly varied between somatic cells and that addition of 0.5% Barodon in BOEC-coculture system may further improve blastocyst development in early bovine embryos.
