These studies were carried out to investigate the effect of Herbal-acupuncture with Inzinsammultang extract on the recovery from liver injury of rats. The liver injury of rats induced with 0.3ml/ea carbon tetrachloride. The Herbal-acupunture with Inzinsam multang extract solution inserted into corresponding focus of Kansu(BL18) in rats. In this study, SD-Rats(Sprague-Dawley) were divided into 4 groups ; Normal group (None treated group), Control-group(The group not treated after $CCI_4$-intoxication), Treated group; Example I-group(Saline-injected groups after $CCl_4$-intoxication) and Example II-group(Inzinsammultang-injected groups after $CCl_4$-intoxication). Through histological observation, Example II-group sho-ws that liver injury is weaker than Control group.(p<0.05) Biochemical assays for each serum enzyme activities of AST, ALT and LDH, levels of albumin, ${\gamma}$-GT, TG, total cholesterol were performed. The results were summarized as follows 1. AST(Aspartate aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 2. ALT(Alanine aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. The Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication(p<0.05) 3. Level of Albumin in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication. 4. LDH(Lactate dehydrogenase) activities in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication.(p<0.05) 5. ${\gamma}$-GT(Glutamyl transferase) in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication(p<0.05) 6. As for the TG(Triglyceride) levels in serum, Inzinsammultang-injected groups after $CCl_4$-intoxication is no significant differences compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 7. Total cholesterol in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication.(p<0.05) Those results indicate that the Inzinsammultang Herbal-acupuncture have significant effects on the liver injury induced by $CCl_4$. So it is expected that the Inzinsammultang Herbal-acupuncture can be used to cure inflammations and recover the functions of damaged liver cells.

The object of this study was to investigate the immune-enhancing effects of Chlorella vulgaris (CV) on a deteriorated immune function by a protein-energy malnutrition (PEM) diet. Unicellular algae, CV were used as a biological response modifier. Male C57BL/6J mice were fed for 15 days with standard diet or a PEM diet, which is associated with decreased host immune defense. After 8 days, mice in the PEM diet group were orally administered by 0.05, 0.1, and 0.15 g/kg body weight of CV or distilled water. Nutritional parameters, and interferon (IFN)-$\gamma$ levels were significantly increased in the blood serum of the CV (0.15 g/kg)-treated group (29.6$\pm$2.8 pg/mL) compared to the non-treated PEM group (4.1$\pm$0.4 pg/mL, p<0.05). In addition, cell proliferation and production of cytokines were investigated via a CV (0.01, 0.1, and 1 mg/mL) treatment using a human T cell line MOLT-4 cell. The CV treatment (1 mg/mL) significantly increased the production of both IFN-$\gamma$ and interleukin (IL)-2 (51.3$\pm$3.4 and 285.9$\pm$18.8 pg/mL, respectively) compared to the control (51.3$\pm$3.4 and 442.6$\pm$14.3 pg/mL, respectively), but did not affect the production of IL-4. These results suggest that CV may be useful in improving the immune function.

This present study was designed to screen medicinal plants for the treatment of brain diseases such as Parkinson's disease or aging. We tested the effects of the water extracts from 38 species medicinal plants on antioxidant capacity, monoamine oxidase B (MAO-B) inhibitory activity, acetylcholinesterase (AChE) inhibition and antiperoxidation activity in vitro. The water extracts from 38 species were tested on their antioxidant activity using radical scavenging effects against ABTS+. The water extract of C. sappan was showed the highest antioxidant capacity, the antioxidant activity at 1 Jig of herbal extract being 0.38mM TE. Lipid peroxidation in brain homogenates induced by NADPH and ADP-Fe/sup 2+/ was strong inhibited by C. sappan and R. palmatum extracts. Among the 38 medicinal plants investigated, R. palmatum showed significant biological activity (antioxidant capacity, MAO-B inhibiory activity, and AChE inhibitory activity). The protective efficacy of R. palmatum water extract on 1-methyl-4­phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism and its possible mechanism were studied in C57BL/6 mice. Treatment of R. palmatum water extract protected biomacromolecules such as lipids from oxidative damage induced by MPTP. The content of MDA in brain tissue was decreased significantly by R. palmatum extract. These results suggest that R. palmatum water extract plays on effective role in attenuating MPTP-induced neurotoxicity in mice. This protective effect of R. palmatum might be estimated the result from the inhibitory activity on monoamine oxidase B and the enhancement of antioxidant activity.

Melanin pigmentation in human skin is a major defense mechanism against ultraviolet light of the sun. Tyrosinase(EC 1.14.18.1) plays a key role in the biosynthesis of ultraviolet of melanin. This is why much researches have been focused on its regulation in controlling the epidermal melanization. We have found that the water-extract of Banha(Pinelliae ternate B.), an oriental medicinal plant, has no tyrosinase inhibitory activity, but does inhibit the melanin biolsynthesis in B16 mouse melanin cells. We also found that Banha extract lowers the tyrosinase activity in cultured cells. To elucidate the action mechanism of Banha extract we have investigated its effect on the tyrosinase mRNA level using reverse transcription-polymerase chain reaction technique. It was revealed that Banha extract reduced the tyrosinase mRNA level in dose dependent manner; when B16 mouse melanoma cells were cultured with 2mg/ml and 5mg/ml of Banha extract, there were 20% and 44% decrease in tyrosinase mRNA level, respectively. These data suggest that the Banha extract exerts its melanogenic inhibitory effect through the transcriptional regulation of tyrosinase mRNA.

Five and a half months after the Keumdong oil spill accident on the 21$^{st}$ of September 1993, 34 seawater samples and 94 sediment samples were collected from Kwangyang Bay and Namhaedo area to assess its environmental impacts. Hydrocarbon concentration in the seawater ranged from 0.8 to 9.2 ${\mu}$g/1 with an average of 3.3 ${\mu}$g/1. This average value was nearly the same as the value(3.7 ${\mu}$g/1) before the oil spill accident. This suggests that by the early March of 1994 majority of the coastal water in the study area restored to its background hydrocarbon concentration before the oil spill accident. Nutrients, heavy metals and other general environmental parameters of the seawater did not show any aggravated seawater quality compared with the previous records. From the regression analysis of time-course observation of hydrocarbon in the seawater, except the sediment environment, the effect of oil spill on the water column was estimated to last at least 4 months in the study area after the oil spill accident. In the shoreline sediments, oil deposits were, however, still found at the high water marks at several stations, and very high values were found in the west of Namhaedo, ranging from 3.7 to 40.1 mg/g of wet sediment. Gas chromatography of these samples showed a very distinct Bunker C chromatogram identical to the Keumdong oil spill. Hydrocarbons in the subtidal bottom sediments in the study area and the reference stations (YB and CB) ranged from 0.45 to 18.08 ${\mu}$g/g of wet sediment with an average of 3.09 ${\mu}$g/g. West of Namhaedo (Stations Bl2-B33) generally showed much higher values than inner Kwangyang Bay and in Chinju Bay. Chinju Bay generally showed the lowest value among the study area. Subtidal bottom sediments in inner Kwangyang Bay and Chinju Bay seemed to be less affected than west of Namhaedo. Heavy metal concentrations in the sediment were relatively higher in the Kwangyang Bay than in the Chinju Bay. However, metal concentrations in the study area were in general comparable to the reference areas.

This study examined the effects of apios (Apios americana Medikus) supplementation on visceral obesity in high-fat diet-induced obese mice. C57BL/6N mice were fed a high-fat diet (40% calories from fat) with or without apios powder (10%, w/w) for 12 weeks. At the end of the experiment, apios supplementation reduced visceral fat mass significantly by 14.3% compared to the control group. Apios decreased significantly the atherogenic index, serum leptin level, hepatic lipid (free fatty acid and triglyceride) content, and lipid droplets, whereas it increased the serum high density lipoprotein-cholesterol/total cholesterol ratio. Hepatic lipogenic gene expression of peroxisome proliferator activated receptor gamma, fatty acid synthase, and diacylglycerol O-acyltransferase 2 was down-regulated by apios supplementation. These results suggest that apios is a healthy food for preventing high-fat diet-induced visceral obesity and fatty liver.

The full encoding sequence for human type II hexokinase (HXK II) was cloned into the E. coli expression vector pET 21b and expressed as a C-terminally hexahistidine-tagged protein in the BL2l (DE3) strain. The IPTG-induced HXK II approximately accounted for 17% of the total E. coli proteins, and 81% of HXK $II_{6{\times}His}$ existed in inclusion bodies. To improve the production of soluble recombinant HXK II protein, in the functionally active form, we used low temperature, and the osmotic stress expression method. When expressed at $18^{\circ}C$, about 83% of HXK $II_{6{\times}His}$ existed in the soluble fraction, which amounted to a 4.1-fold yield over that expressed at $37^{\circ}C$. The soluble form of HXK $II_{6{\times}His}$ was also highly produced in the presence of 1M sorbitol under the standard condition $(37^{\circ}C)$, which indicated that temperature downshift and low water potentials were required to improve the yield of active recombinant HXK II protein. The expressed protein was purified by metal chelate affinity chromatography performed in an IDA Excellose column charged with $Ni^{2+}$ ions, resulting in about 40mg recombinant HXK II protein obtained with purity over 89% from 51 of E. coli culture. The identity of HXK $II_{6{\times}His}$ was confirmed by Western blotting analysis. Taken together, using the stress-governed expression described in this study, human active HXK II can be purified in sufficient amounts for biochemical and biomedical studies.

Bovine Pneumonic Pasteurellosis는 수송열(輸送熱)로 일반적으로 알려져 있는 질병으로서, 여러가지 요인의 복합적(複合的)인 작용에 의해 발병하는 것으로 알려져 있으나, Pasteurella haemolytica A1이 가장 주요(主要)한 인자(因子)로 밝혀져 있다. P haemolytica A1은 leukotoxin(LKT), lipopolysaccharide(LPS), capsular polysaccharide 등 여러가지의 병원성인자(病原性因子)을 생성한다. 이들 인자중 LKT가 가장 중요한 병원성인자로 밝혀져 있다. 이에 본 실험은 P haemolytical A1의 LKT 유전자를 Bacillus subtilis에서 발현(發現)시킴으로서 LPS에 오염(汚染)되지 않은 LKT을 대량으로 생산할 목적으로 실시되었다. 실험의 첫 단계(段階)로서 pLKT52 plasmid을 Sau3 A1의 제한효소을 이용하여 부분소화(部分消化)시킨 후 이 부분 소화(消化)된 유전자들로부터 3~5kb 크기의 유전자들을 순수분리하여 pUC18와 결합시킨 후 E coli NM522에 형질전환(形質轉換)시켰다. 이때 형질전환된 균주들은 LKT에 대한 단크론 항체인 MAb601을 이용하여 colony blot 법에 의해서 LKT 유전자 보유 및 발현여부(發現與否)을 조사하였다. 이들 양성 clone들은 제한효소분석(制限酵素分析), 염기서열분석(鹽基序列分析) 및 Western blot 등에 의해서 재확인(再確認)하였다. 총 9개의 양성 clone중 위의 방법에 의해서 한 clone을 선택(選擇)하여 lktCA insert를 재분리하여 shuttle vector에 subcloning 하였다. Subcloning된 LKT 유전자들은 shuttle vector의 종류(種類)(pHPS9, p602/20, pHPS9-Sac)와 각기(各其) 다른 종류(種類)의 B subtilis(spoO12A, BR121, WB3O, Raj1105) 숙주내(宿主內)에서 발현정도를 Western blot 법에 의해서 비교(比較)하였다. 이때 최적발현조건(最適發現條件)은 p602/20와 pBL1의 dual plasmid system을 이용하여 B subtilis spoO12A에서 2시간동안 IPTG로 발현을 유도(誘導)하는 것이었다. B subtilis에서 발현된 LKT을 visual 법과 neutral red uptake 법을 이용하여 소 폐포(肺胞) 대식구(大食求)에 대한 biological activity를 확인하였다. 발현된 LKT에 대한 LPS 오염은 LKT을 SDS-PAGE 후 silver stain에 의해서 확인하였다. 본 실험을 통해서 볼 때에 lktCA 유전자를 보유(保有)하고 있는 p602/20는 B subtilis에서 매우 불안정(不安定)하였고, 발현된 LKT는 세균자체(細菌自體)에서 생성되는 protease들에 의해서 파괴(破壞)됨으로서 농도(濃度)가 매우 낮았다. 이러한 문제점들은 다음 단계(段階)의 실험에서 해결되어야할 문제들이다.
