This study was conducted to investigate the effects of Woohwangcheungsimweun (ox bezoar), deer antlers, and wild ginseng on induction of cardiomyocyte differentiation using the established mouse embryonic stem (ES) cells. The expression of atrial natriuretic peptide (ANP) was highest in Woohwangcheungsimweun treatment group. The expression of rabbit anti-GATA-4(GATA-4) and troponin (TnI) were highest in wild ginseng and Woohwangcheungsimweun treatment groups, respectively. Fluorescence activated cell sorting (FACS) analysis showed that the expression of ANP was highest in Dimethyl sulfoxide(DMSO) and Woohwangcheungsimweun treatment groups. The expression of GATA-4 was relatively high in wild ginseng treatment group. The expression of TnI was highest in Woohwangcheungsimweun treatment group. In the gene expression analysis, DMSO greatly inhibited GATA-4 expression to 25% of control. Woohwangcheungsimweun treatment caused to increase cTnI and cardiac ANP expression significantly. Wild ginseng extract upregulated GATA-4 gene expression. In conclusion, DMSO widely used as cardiomyocyte differentiation inducer did not show significant effects on the expression of ANP, GATA-4 and TnI in this study. Woohwangcheungsimweun showed upregulation of ANP and TnI expression. Wild ginseng extract showed greater effects than DMSO on GATA-4 expression. These results might suggest that the combination of Woohwangcheungsimweun and wild ginseng extract treatment can be expected to increase expressions of all three genes.

This paper makes an analysis of the ecological behaviours of 3 categories of quails, namely wild Japanese quails from the Weishan Lake Area, medium-sized domestic quails and pint-sized domestic quails. The study indicates as follows: (1) There is difference in morphological and biological habits between domestic quails and wild Japanese ones. (2) The cross-breeding between the wild and domestic quails is a cross from exclusion to affinity. (3) The behaviours of quails such as pursuit,paw and mating are selective. (4) The wild Japanese quails and domestic ones can succeed in mating and in reproducing fertilized eggs but with a low rate. (5) Evolutionary differentiation has been formed in varying degrees between the domestic quails and their wild ancestors in morphological and ecological characteristics.

Objective: Panax ginseng is one of the most medicinally used herbal medicines in the world. Wild ginseng is widely accepted to be more active than cultivated ginseng in chemoprevention. However, little has actually been reported on the differences between wild ginseng and cultivated ginseng. Method: To identify wild ginseng-specific genes, we used suppressive subtraction hybridization. Results: We report that one of the clones isolated in this screen was the GAPDH (glyceraldehyde 3-phosphate dehydrogenase) gene (designated pGAPDH-w). DNA BLAST sequence analysis revealed that this pGAPDH-w gene contained novel sequences of 94 bp. RT-PCR results showed that the expression of the pGAPDH-w gene was significantly up-regulated in the wild ginseng as compared with the cultivated ginseng. Conclusion: The pGAPDH-w gene may be one of the important markers of wild ginseng.

The rigor-mortis progress of cultured olive flounder spiked at the brain started much faster than that of wild one. They attained full rigor state after 30 hrs at $0^{\circ}C$, 36 hrs at $5^{\circ}C$ and 50 hrs at $10^{\circ}C$ in the cultured flounder, while after 36 hrs at $0^{\circ}C$, 50 hrs at $5^{\circ}C$, and 60 hrs at $10^{\circ}C$ in the wild. ATP concentration in the muscle was around $5.9\mu mol/g$ for wild and $6.2\mu mol/g$ for cultured flounder. ATP breakdown progressed rapidly in $0^{\circ}C$ samples, followed by $5^{\circ}C$ and $10^{\circ}C$ samples. $Mg^{2+}$-ATPase activity of myofibrillar protein in the presence of 0.25mM CaCb was higher in cultured myofibri1lar protein than in wild one. $Mg^{2+}$-ATPase activities of myofibrillar protein increased during storage in samples stored at $0^{\circ}C$ and $5^{\circ}C$ while decreased in samples stored at $10^{\circ}C$. The level of breaking strength of muscle immediately after death was higher in the wild muscle than in the cultured muscle. The breaking strength reached maximum level at 10 hrs after death in both samples.

The occurrence of wild boars (Sus scrofa Linnaeus) and reports of wildlife-vehicle conflicts (i.e., road-kill) involving them have increased in natural forest regions of Korea. In the past few decades, many wildlife passages have been constructed to reduce vehicle collisions involving wildlife species. However, few studies have assessed the habitat suitability of target wildlife species when locating the construction sites of wildlife passages. Target species rarely use wildlife passages if built in an inappropriate location. Therefore, a quantitative habitat model is required to find suitable sites for wildlife passages that can connect the fragmented forest patches of wildlife habitats in Korea. In this study, the wild boar was selected as the target species, and six environmental variables (percentage of Quercus forest, slope aspect, distance to roads, water accessibility, forest stand age and density) were measured. The habitat model for wild boars was developed with a Delphi survey, and habitat suitability maps were delineated for the provinces of Gangwon-do and Jeollanam-do. In this study, 298 and 64 boars were observed in Gangwon-do and Jeollanam-do, respectively. Observations of wild boars derived from the second nationwide natural environmental survey were used to evaluate the habitat model. Habitat suitability maps that superimposed existing road networks suggested that wild boar habitats were severely fragmented in both provinces, particularly in Gangwon-do. To connect the fragmented habitats and prevent wildlife-vehicle collisions, this study proposes 11 and 5 wildlife passage sites in Gangwon-do and Jeollanam-do, respectively.

The glycogen-associated protein phosphatase (PP1G/$R_{GL}$) may play a central role in the hormonal control of glycogen metabolism in the skeletal muscle. Here, we investigated the in vivo epinephrine effect of glycogen metabolism in the skeletal muscle of the wild-type and $R_{GL}$ knockout mice. The administration of epinephrine increased blood glucose levels from 200±20 to 325±20 mg/dl in both wild-type and knockout mice. Epinephrine decreased the glycogen synthase -/+ G6P ratio from 0.24±0.04 to 0.10±0.02 in the wild-type, and from 0.17±0.02 to 0.06±0.01 in the knockout mice. Conversely, the glycogen phosphorylase activity ratio increased from 0.21±0.04 to 0.65±0.07 and from 0.30±0.04 to 0.81±0.06 in the epinephrine trated wild-type and knockout mice respectively. The glycogen content of the knockout mice was substantially lower (27%) than that of both wild-type mice; and epinephrine decreased glycogen content in the wild-type and knockout mice. Also, in Western blot analysis there was no compensation of the other glycogen targeting components PTG/R5 and R6 in the knockout mice compared with the wild-type. Therefore, $R_{GL}$ is not required for the epinephrine stimulation of glycogen metabolism, and rather another phosphatase and/or regulatory subunit appears to be involved.

Panax ginseng is a well-known herbal medicine in traditional Asian medicine, and wild ginseng is widely accepted to be more active than cultivated ginseng in chemoprevention. However, little has actually been reported on the difference between wild ginseng and cultivated ginseng. Thus, to identify and analyze those differences, we used suppressive subtraction hybridization (SSH) sequences with microarrays, realtime polymerase chain reaction (PCR), and reverse transcription PCRs (RT-PCRs). One of the clones isolated in this research was the chloroplast rpoC1 gene, a ${\beta}$subunit of RNA polymerase. Real-time RT-PCR results showed that the expression of the rpoC1 gene was significantly upregulated in wild ginseng as compared to cultivated ginseng, so, we conclude that the rpoC1 gene may be one of the important markers of wild ginseng.

This study evaluates the effects of cultured wild ginseng root (0.05%, 0.1% v/w) and xylitol in kimchi. The fermented characteristics of kimchi were investigated during 28 days of fermentation at $4^{\circ}C$. The pH value in the sample with the cultured wild ginseng root was higher than that of control group. The total acidity in the sugar groups (SG groups) was higher than that of xylitol groups (XG groups). Comparing total bacterial count, XG groups were lower than SG groups, regardless of the additional ratio of the cultured wild ginseng root. Reducing sugar of XG groups decreased more slowly than SG groups for seven days; glucose and fructose of XG groups were lower than the control group. DPPH radical scavenging activity was higher in groups with cultured wild ginseng root than in control. In the result of sensory evaluation, XG groups were more preferred than other groups. In conclusion, our results indicate that cultured wild-ginseng root and xylitol have a positive effect on the quality of kimchi, such as antimicrobial and antioxidant functions.

Panax ginseng is a well-known herbal medicine in traditional Asian medicine. Although wild ginseng is widely accepted to be more active than cultivated ginseng in chemoprevention, little has actually been reported on the difference between wild ginseng and cultivated ginseng. Using suppressive subtraction hybridization, we cloned the p-psbB gene as a candidate target gene for a wild ginseng-specific gene. Here, we report that one of the clones isolated in this screen was the chloroplast p-psbB gene, a chlorophyll a-binding inner antenna protein in the photosystem II complex, located in the lipid matrix of the thylakoid membrane. Real-time results showed that the expression of the p-psbB gene was significantly up-regulated in wild ginseng as compared to cultivated ginseng. Thus, the p-psbB gene may be one of the important markers of wild ginseng.
