The gestation period and parturition days were accurately predicted by measuring progesterone concentration in the plasma from 40 pregnant companion bitches. The mean length of the estrous cycle based on plasma progesterone concentrations were 8.14 ± 1.39 (Mean ± SD) days for proestrus, 9.19 ± 2.01 days for estrus, and 55.38 ± 1.96 days for diestrus phase, respectively. The gestation length from each based on the days was 65.61 ± 2.47 days from the first day of estrus after the first vaginal discharge, 63.21 ± 0.99 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54.51 ± 3.51 days from the first day of diestrus, respectively. Therefore, the parturition day was estimated 65 days from the first day of estrus after the first vaginal discharge, 63 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54 days from the first day of diestrus, respectively.

Serial ultrasonographic examinations were performed on 9 pregnant Korea Jin-do dog from days 15 to 60 to determine the size of gestational structures throughout pregnancy. Gestational age was timed from the day of ovulation (Day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. Extra-fetal structures were measureable from days 17 to 49. Outer uterine diameter increased from $7.0{\pm}0.7$ ($mean{\pm}SD$)mm at day 17 to $54.0{\pm}2.2mm$ at day 49 and inner chorionic cavity diameter increased from $3.0{\pm}0.7mm$ at day 17 to $37.5{\pm}0.6mm$ at day 49. Uterine wall thickness increased from $2.8{\pm}0.4mm$ at day 17 to $8.3{\pm}0.5mm$ at day 49, placental thickness increased from $1.0{\pm}0.1mm$ at day 22 to $5.7{\pm}0.2mm$ at day 49 and length of chorionic cavity or zonary placenta increased from $5.5{\pm}1.3mm$ at day 20 to $52.3{\pm}2.2mm$ at day 49. Inner chorionic cavity diameter, outer uterine diameter and placental length each increased at a linear rate through day 37, after which time, each had a marked plateau in growth. Of the extra-fetal structures, inner chorionic cavity diameter was the most accurate for estimation of gestational age until day 37. Fetal structures were measureable from days l7 to 60. Crown-rump length, increased from $3.0{\pm}0.7mm$ at day 22 to $118.7{\pm}3.1mm$ at day 49, fetal body diameter increased from $4.0{\pm}0.7mm$ at day 25 to $55.8{\pm}1.7mm$ at day 60 and fetal head diameter increased from $4.3{\pm}0.6mm$ at day 26 to $29.8{\pm}0.8mm$ at day 60. Of the fetal structures, fetal head diameter was the most accurate for estimation of gestational age from day 37 until day 60.

Purpose: This study aims to examine effect of microcurrent electrostimulation on burn healing by electric intensity and of which the electric intensity on the acute burn being cured with microcurrent electrostimulation therapy. Methods: 28 Sprague Dawley Rats is classified into a control group of 8 rats, an experimental group I of 10 rats and an experimental group II of 10 rats. The control group is not cured, the experimental group I is exposed to 10 Hz, and $100{\mu}A$ with microcurrent electrostimulation, and the experimental group II is exposed to 10 Hz, $300{\mu}A$ for 15 minutes a day. The next day, 2th, 4th, and 6th day after rats is burned. Result: There are not significant differences of length change of the burn cure between the control group, the experimental group I, and the experimental group II by a period. However, systematically hair follicle cell on the 2th day and epidermal cell on the 6th day turn up in the experimental group I, and the experimental group II. Inquiry: Nancy(1994) did not obtain the desired result when the skin of a pig is exposed to 0.1 Hz, and $100{\mu}A$ for wound healing. In the result of the study, when burn length is measured on the 2th, 4th, and 6th to see the length change of acute burn, there is not significant differences among 3 groups. Conclusion: Statistically, there is not significant differences of the length change between 3 groups. However, systematically the burn is cured faster in the experimental group I, and the experimental group II than in the contrast group.

This study was determined the hair growth effect and mode of action of a complex extract (abelmo), extracted from various natural plants including Acorus calamus var. angustatus. 30 six-week old C57BL/6 mice were randomly assigned into three treatment groups with ten mice per treatment group repeatedly. The treatment group is a control group, and was classified into saline-applied, minoxidil 5%-applied, and abelmo-applied groups. Hair growth started from the abelmo-applied and minoxidil 5% -applied groups on the 9th day, compared to the saline-applied group. Hair growth rate was 17.06% and 19.15% in those two groups, respectively, and the abelmo-applied group's hair growth rate was higher. The density, length and thickness of hair were significantly higher in the order of abelmo-applied group, minoxidil 5%-applied group and saline-applied group on the 9th day, and hair root was strongly maintained in the abelmo-applied group. The density, length and thickness of hair in the abelmo-applied group were significantly higher by 599.8, 122.2 and 181.8% on the 9th day compared to the saline-applied group, and 166.7, 171.4 and 200.2% on the 12th day, and 136.6, 216.9 and 180.7%, respectively on the 15th day. As for hair follicle and the length of hair shaft from the dosal skin histopathology manifestation, the abelmo-applied group was more excellent than the saline-applied group and minoxidil 5%-applied group. This result actually confirmed the fact that abelmo promotes hair growth and strongly maintains hair root simultaneously.

The heading response of 40 genotypes, originated from South Korea, North Korea, and northern China, was tested under the temperature and day-length conditions of thirteen major rice production area in North Korea, with aims to select adaptable varieties to the given environment and crop period for each region. To simulate regional environment, seven-day mean temperature with 10℃ daily temperature range and day-length for each region were imposed at a weekly interval in the walk-in phytotrons. Olbyeo1, Olbyeo2 and Sonbong9 originated from North Korea, Kenjiandao3 and Nongdae3 from northern China, and Joun from South Korea demonstrated the earliest heading stage depending on the regional environment. Thirty-four varieties reached heading stage within the regional safe marginal heading date (SMHD) under Haeju and Sariwon conditions while 16-17 varieties reached the stage under Wonsan, Changjon, Supung, and Yongyon environment. Some of the middle and mid-late maturing varieties originated from South Korea could reach heading stage within SMHD under the temperature and day-length conditions of Kaesong, Haeju, Sariwon, Nampo, and Pyongyang located in west-southern plain. Majority of early maturing varieties, but not middle or mid-late ones, showed heading stage within SMHD under the conditions of Singye, Anju, Kusong and Sinuiju. Only some early maturing varieties demonstrated heading stage within SMHD under Yongyon, Changjon and Wonsan environment. These results provide basic information on the varieties able to complete their normal life cycle under the regional environment in North Korea. It it further suggested that yield performance of the selected varieties for each region in this study be tested to select high yielding rice varieties adaptable to North Korean environment.
