This study was conducted to investigate changes of blood metabolites and enzyme activities at different slaughter ages of Hanwoo cattle. Blood samples were taken from six hundred thirty two steers (24~33 months of age) and one hundred twenty eight bulls (17~24 months of age) by venipuncture from caudal vein immediately prior to slaughter. Glucose concentrations were linearly increased (P<0.001) with increases of the slaughter age in steers, and blood urea nitrogen (BUN) concentrations were linearly decreased (P<0.001) with increases of the slaughter age in steers. Likewise, glucose and albumin concentrations in bulls were linearly decreased (P=0.009 and P<0.001, respectively) with increases of the slaughter age. BUN, cholesterol, triglycerides, and total cholesterol concentrations were linearly increased (P<0.001, 0.018 and 0.002, respectively), and creatinine concentrations were quadratically increased (P=0.009) with increases of the slaughter age. Activity of gamma glutamyltransferase (${\gamma}$-GT) and aspartate aminotransferase (AST) was linearly increased (P<0.001) with increases of the slaughter age in both steers and bulls, whereas alanine aminotransferase (ALT) was not affected by increasing slaughter age. In addition, the concentrations of ${\gamma}$-GT and AST were higher (P<0.05) for bulls than those of steers at 24 months of age. Increased levels of ${\gamma}$-GT and AST indicate impaired liver function; it may be associated with increases of concentrate level which is a concomitant of the extended fattening periods in Hanwoo feeding. In conclusion, the results in the present study may be one of the useful information for diagnosis of the metabolic disorder in Hanwoo cattle.

Objectives : The present study attempted to reveal the effects of the combination of Fel Ursi and Bezoar on the improvement of the function of the liver, through examining the effects of Fel Ursi, Bezoar, and Woong-Whang Tang composed of Fel Ursi and Bezoar. Method : Acute hepatitis was induced by galactosamine to rats, and then Fel Ursi, Bezoar Bovis, and Woong-Whang Tang were introjected to measure the influence of serums such as AST, ALT, ALP, ${\gamma}GT$, and lipid peroxide of liver tissues which are considered as the index of the function of the liver. Results : 1. Fel Ursi decreased the lipid peroxide of ALT, ${\gamma}FT$, and liver tissue and that of mitochondria in liver tissues of the rats with galactosamine-induced acute hepatitis, but it did not have any significant effect on AST and ALP. 2. Bezoar Bovis decreased the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues among serum of the rats suffering from acute hapatitis induced by galactosamine, but it did not have any significant effect on that of mitochondria of the liver tissues. 3. Woong-Whang Tang had a significant effects on the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues, and on the decrease of lipid peroxide of mitochondria, among serum of the rats suffering from acute hapatitis induced by galactosamine. Conclusion : Fel Ursi and Bezoar Bovis were judged to be effective on the acute hepatitis of the liver by galactosamine. In particular, Woong-Whang Tang which was composed of the combination of Fel Ursi and Bezoar Bovis was more efficient in the improvement of the function of the liver and the amount of lipid peroxide than the respective use of Fel Ursi or Bezoar Bovis.

This study was carried out to examine the action mechanism of Chamaecyparis obtusa oil (CO) on hair growth in C57BL/6 mice. For alkaline phosphatase (ALP) and ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) activities in the skin tissue, at week 4, the 3% minoxidil (MXD) and 3% CO treatment groups showed an ALP activity that was significantly higher by 85% (p < 0.001) and 48% (p < 0.05) and an ${\gamma}$-GT activity that was significantly higher by 294% (p < 0.01) and 254% (p < 0.05) respectively, as compared to the saline (SA) treatment group. For insulin-like growth factor-1 (IGF-1) mRNA expression in the skin tissue, at week 4, the MXD and CO groups showed a significantly higher expression by 204% (p < 0.05) and 426% (p < 0.01) respectively, as compared to the SA group. At week 4, vascular endothelial growth factor (VEGF) expression in the MXD and CO groups showed a significantly higher expression by 74% and 96% (p < 0.05) respectively, however, epidermal growth factor (EGF) expression in the MXD and CO groups showed a significantly lower expression by 66% and 61% (p < 0.05) respectively, as compared to the SA group. Stem cell factor (SCF) expression in the MXD and CO groups was observed by immunohis-tochemistry as significant in a part of the bulge around the hair follicle and in a part of the basal layer of the epidermis. Taking all the results together, on the basis of effects on ALP and ${\gamma}$-GT activity, and the expression of IGF-1, VEGF and SCF, which are related to the promotion of hair growth, it can be concluded that CO induced a proliferation and division of hair follicle cells and maintained the anagen phase. Because EGF expression was decreased significantly, CO could delay the transition to the catagen phase.

The hair cycle consists of three phases, growth (anagen), involution (catagen) and quiescence (telogen) phases. In order to evaluate hair re-growth effect of herbal extracts mixture containing the 70％ ethanol extracts of Polygoni Multiflori Radix, Mori Cortex Radicis, Gingko Biloba Folium and Pine bud, we have examined the induction of the anagen phase and/or elongation of the anagen period using C3H mice. Morphological examination was done by Hattori' and Ogawa's method. Enzyme activities of ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) and alkaline phosphatase (ALP) was detected by Bessey-Lovry-Brock's method. Enzyme activity as a biochemical marker of hair cycle was investigated in the third hair cycle period of C3H mice after depilation. 3％ Minoxidil treated group and herbal extract mixture treated group were shown 3 days earlier initiation of anagen than control group. In cycling mouse skin, ${\gamma}$-GT activity is pronounced during anagen and greatly diminished during telogen. Herbal extract mixture has shown promising hair re-growth effect on hair follicular cycles of C3H mice.

The chickens fed with the feeds supplemented with green tea(GT) and lactic acid bacteria(LB) were infected orally with 10,000 oocysts per chicken of E. maxima. The groups administered with the feeds supplemented with GT by 0.5% and 2.0% of feed showed the significant levels of decreasing in the number of oocysts shed for 5 days after E. maxima infection. The feeds supplemented with LB by 0.1% and 0.5% of feed were less effective in reducing the number of the fecal oocyst, compared with the groups administered with GT. To evaluate the immunoregulatory effects of the feed additives, the expression patterns of IL-2 and IFN-r in spleen cells were studied by RT-PCR and ELISA. The higher levels of IL-2 transcripts after E. maxima infection were observed in the groups with n, compared with the groups with LB and the mixture of GT and LB. The $IFN-\gamma$ mRNA bands were observed in the all of experimental groups except the uninfected control. The culture supernatants of Con A-stimulated spleen cells($5{\times}10^6cells/ml$) were measured for the concentration of IL-2 and $IFN-\gamma$ by ELISA. The levels of IL-2 and $IFN-\gamma$ on days 3 and 7 after E. maxima infection were significantly augmented in the groups with n. These results indicated that GT-supplemented feeds resulted in higher reduction of oocyst-shedding and more enhanced immune responses in the chicken infected with E. maxima, as compared with LB-supplemented feeds. According to the results, it was implicative that the supplements could be utilized for development of feed additives for anti-coccidiosis.

Xenopus oocytes를 이용하여 인삼의 유효 성분으로 알려진 Ginseng total saponin(GTS)의 신호 전달 기작을 two electrode voltage clamp 방법을 이용하여 연구하였다. GTS는 세포 바깥에 처리했을 때 -2OmV보다 더 positive한 voltage에서 커다란 outward current를 유도하였다. 그러나, 세포 안쪽에 GTS를 injection할 경우 아무런 효과가 없는 것으로 나타났다. GTS처리에 의한 outward current유발 효과는 GTS 투여 용량에 의존적인 것으로 나타났다(EC$_{50}$ : 4.4 $\mu\textrm{g}$/ml). GTS의 작용은 $Ca^{2+}$-activated Cl- channel blocker인 niflumic acid에 의하여 차단되었다. 칼슘 chelator인 BAPIA와 IP$_3$ 수용체 길항제인 heparin을 세포내 injection에 의하여 차단되었다. 또한 active phospholipase C inhibitor(PLC)인U-73122를 세포 바깥에 전처리할 경우에도 GTS의 작용이 부분적으로 억제되는 것으로 나타났다. 백일해 독소를 전처리할 경우GTS의 작용은 억제되지 않은 것으로 나타났으나, GTP analog인 GTP${\gamma}$S를 세포내 injection할 경우 GTS의 작용은 억제되는 것으로 나타났다. 이러한 연구 결과는 GTS가 oocytes세포막 성분과 상호 작용에 의하여 $Ca^{2+}$-activated Cl- channel이 열리도록 하고, 이 과정에 PLC활성 및 백일해 독소에 민감하지 않은 G단백질활성 및 IP3에 민감한 세포내 $Ca^{2+}$-activated로부터 칼슘 방출을 유도하는 것으로 나타났다났다

A cDNA encoding chicken interferon-gamma (chIFN-${\gamma}$) was amplified from P34, a CD4$^{+}$ T-cell hybridoma by reverse transcription-polymerase chain reaction (RT-PCR) and cloned into pUC18. THe sequences of cloned PCR products were determined to confirm the correct cloning. Using this cDNA as probe, chicken genomic library from White Leghorn spleen was screened. Phage clones harboring chicken interferon-gamma (chIFN-${\gamma}$) were isolated and their genomic structure elucidated. The chIFN-${\gamma}$ contains 4 exons and 3 introns spanning over 14 kb, and follows the GT/AG rule for correct splicing at the exon/intron boundaries. The four exons encode 41, 26, 57 and 40 amino acids, respectively, suggesting that the overall structure of IFN-${\gamma}$ is evolutionairly conserved in mammalian and avian species. The 5’-untranslated region and signal sequences are located in exon 1. Several AT-rich sequences located in the fourth exon may indicate a role in mRNA turnover. The 5’-flanking region contains sequences homologous to the potential binding sites for the mammalian transcription factors, activator protein-1(AP-1) activator protein-2(AP-2) cAMP-response element binding protein(CREB), activating transcription factor(ATF), GATA-binding fator(GATA), upstream stimulating factor(USF), This suggests that the mechanisms underlying transcriptional regulation of chicken and mammalian IFN-${\gamma}$ genes may be similar.r.
