This experiment was carried out to investigate the effects of different IVM-IVC culture media factors, such as development rates according to the maturation media, collecting times from slaughter to initiation of incubation and with cumulus cells, on in vitro maturation of oocytes collected from 3∼5mm diameter follicles of the swine abattoir The development rates significantly(p<0.05) higher when the oocytes were matured TCM-199 media than NCSU-23 media. In comparing with TCM199 medium in presence of Earle's salts and Hank's salt, there were no significantly differences between each salt balance in cleaved rate and in number of morulae plus blastocyst. Among 1,455 immature oocytes, 999(68.6％) of oocytes were cleaved. The number of development to the morulae and blastocysts were 617(61.8％) include 62 balstocysts(6.2％).

In order to find out nutritional effects of Korean edible mushrooms on the multiplication of tissue cells, the alcohol extracts and acid bydrolysates of eleven species of mushrooms were added to Earle's ESS. A comparison of the respective multiplications of HeLa cells in this solution and in control solution of TC=199. Yielded the following result: The alcohol extracts and acid hydrolysates of a Coprinus comatur, Agaricus campestris, Agaricus bisporus, Lentinus edodes, Tricholoma matsutake, Pleurotus ostretus, Ramaria botrytis and Pholiota nameko influenced favorably the maintenance of the normal form and monolayer of HeLa cells. The growth curves of HeLa cells in the cultures containing, respectively, the alcohol extracts and acid hydrolysates of these eight mushrooms showed that five species, i.e., Coprinus comatus, Agaricus compestris, Agaricus bisporus, Lentinus edodes and Tricholoma matsutake effected an excellent multiplication and that the other three species were less effective than those five species. As to the effects on the cell multiplication, no marked difference was observed between the alcohol extracts and the acid hydrolysates of the mushrooms tested.
