Effects of the protein fraction of Panax ginseng on chicken embryonic skeletal muscle cells cultured with a decfiient medium were studied. The protein fraction was further fractionated into four groups according to the molecular weight; larger than 10,000 dalton(fraction A), between 5,000 and 10,000 dalton(fraction B), between 1,000 and 5,000 dalton(fraction C), between 500 and 1,000 dalton(fraction D). According to the microscopic observation, all four protein fractions at the concentration of $10{\sim}100{\;}{\mu}g/ml$ showed the tendency to stimulate the growth and differentiation of the muscle cells. The activity of acetylcholinesterase in muscle cells was significantly elevated by the protein fraction A at the concentration of $100{\mu}{\;}g/ml$. Protein fractions B,C and D significantly enhanced the synthesis of RNA in the muscle cells. The synthesis of DNA in muscle cells was significantly enhanced by protein fractions A,B and C.

Effects of dammarane glycosides of Panax ginseng on primary cultured chicken embryonic skeletal muscle cells were studied by microscopic observation and determination of the activity of acetylcholinesterase. Muscle cells were prepared from the breast of 12-day-old chicken embryo and cultured with either a medium consisted of 87.5% Dulbecco's Modified Eagle Medium (DMEM), 10% horse serum and 2.5% chicken embryonic extract or a medium consisted of 90% DMEM and 10% horse serum. It was observed that dammarane glycosides of Panax ginseng seemed to show the tendency to stimulate the growth and the differentiation of the muscle cells cultured with a medium consisted of 90% DMEM and 10% horse serum under microscopic observation. The activity of acetylcholinesterase in the muscle cells cultured with a medium consisted of 90% DMEM and 10% horse serum was increased by dammarane glycosides of Panax ginseng.

Polyamines of Korean red ginseng were extracted with 5% trichloroacetic acid and purified by ion exchange chromatography using Dowex-50Wx8 resin. Four spots having R$_f$ values of 0.19, 0.28, 0.35, and 0.45 were detected. It was observed under microscopy that those polyamines stimulated the growth and differentiation of chicken embryonic muscle cell. The development of muscle cells from the stage of myoblast to that of myotube was found to be enhanced by those polyamines. It was also observed that those polyamines most likely lengthened, the life-span of the cultured chicken embryonic skeletal muscle cells.
