This experiment was carried out to investigate the effect of energy and protein levels during the gestation period on milk yield, milk composition and pre- and post-partum body weight of darn in Korean native cows. In this experiment, thirty six heads of pregnant cows were allotted to a 3×3 factorial design with three net energy levels (80, 100, 120% of NRC ) and three crude protein levels (80, 100. 120% of NRC) for 90 days before parturition. thereafter those were fed at the same nutrient level (100% of NRC) from calving to weaning for 180 days. The results obtained from this experiment are summarized as follows; 1. Pregnant cow`s body weight during the pre-partum 90 days was changed with a significant difference (P$lt; 0.05) from 16㎏ increase of the NE 80%-CP 80% to 42.4㎏ increase of the NE 120%-CP 120%. 2. Dam`s post-partum body weight for 180 days was decreased to the post-partum 127th day and thereafter it was slowly increased, and the difference of the body weight between right after parturition and at weaning was 25.4㎏, which accounted for 5.7% of the body weight, without a significant difference by pre-partum NE-CP level. 3. The average daily milk yield of nursing cow with 10-day intervals for 180 days was not significantly different, showing 2.82㎏ of the NE 80%-CP 80% and 4.03㎏ of the NE 80%-CP 120% (average 3.50㎏), although the difference was 1.21㎏. 4. The maximum of average daily milk yield with 10-day intervals for 180 days was 4.48 to 6.10㎏ (average 5.46㎏) without a significant difference by pre-partum NP-CP levels. and it showed its maximum yield at 5 to 12th day (average 10th day) without it significant difference by treatment. 5. The decrease rate per week and quantity per day of average daily milk yield for 18(1 days showed a significant difference (P$lt;0.05) from 2.38% and of the NE 80%-CP 120% to 3.27% and 25.48 of the NE 100%-CP 80%), respectively. 6. The physico-chemical properities and constituents of milk were not significantly different by pre-partum NE-CP levels, and the energy value of milk per ㎏ was 782 to 849㎉ (average 824㎉). 7. The results showed that energy level affected significantly only the pre-partum body weight of dam for 90 days. However, protein level affected significantly only the milk yield of the nursing cow from calving to weaning for 180 days.

Impatiens balsamine Linne(Balsaminaceae) known as BONG SUN HWA in Korea and has been used for the treatment of scrofulosis, carbunculus and dysenteria etc. Bioassay-guided fractionation of MeOH extract from the whole plants of Impatiens balsamina has afforded a simple naphthoquinone derivative, 2-methoxy-1, 4-naphthoquinone. The structure of this compound was established by spectroscopic methods. This compound possessed strong antifungal activity against Candida albicans, Aspergi Ilus niger, Crytococcus neoformans and Epidermophyton floccusum. The activity of 2methoxy-1, 4-naphthoquinone on E. ,floccusum (MIC : 5.0 ㎍/㎖) was the same potency as that of nystatin. It showed also strong antibacterial activity against gram-positive bacteria Bacillus subtilis as well as gram-negative bacteria Salmonella typhimurium. Although the activity of this compound on gram-negative bacteria was lower than that of gram-positive bacteria.
