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.
