Due to the lowering of biological functions resulted from old age, the elderly is known to have many different clinical laboratory data compared with the young adults. But, in korea, such study is lacking. This research is to find the differences between the elderly and the young adults, and also to know the sexual differences, by comparing the outcomes of the clinical. laboratory data. Along with that, it is to help clinical usage of the data in the future. The age of the elderly was between 60 and 83(average age 63.8), and that of the young. controls was between 20 and 35. In both sexes, MCV, MCH, ESR, CRP, AST, ALT, ${\gamma}$GTP, ALP, BUN, total cholesterol were significantly higher in the elderly than in the controls. And lymphocyte count(%), total bilirubin, direct bilirubin, total protein, albumin, $T_3$ were significantly lower in the elderly than in the controls(P<0.05). Hemoglobin, Hct, platelet count, $T_4$ were significantly lower only in the male elderly, and eosinophil count(%), creatinine were significantly higher only in the female elderly(P<0.05). HDL cholesterol was significantly higher only in the male elderly(P<0.01). There were no significant difference between two groups regarding WBC count, segment neutrophil count(%), monocyte count(%), TSH. Many clinical laboratory data are different between the elderly and the young adults, and some clinical laboratory data also have sexual differences.

For the research of the natural marine antioxidant, several bacteria were isolated from the coast of jin-Hae in Korea. Among the marine bacteria studied, strain HJ-14, a gram-negative, motile, strait rod, aerobic, and $Na^{+}$ required bacterium showed high activity of 1,1-diphenyl-2-picrylhydrazyl radical scav- enging. The morphological, physiological, and biochemical characteristics of the strain HJ-14 were similar to those of the Alteromonas macleodii ATCC $27126^{T}$ . Thus, it was tentatively identified as Alteromonas sp. HJ-14. The compositions of major fatty acids in cell membrane of Alteromonas sp. HJ-14 were $C_{ 14:0}$ , $ C_{15:0}$ , $C_{16:0}$ and $C_{17:1}$ $_{w8c}$ , which also suggest that it is affiliated with Alteromonas sp. The optimum culture conditions for production of antioxidant materials with Alteromonas sp. HJ-14 were at $25$~$37^{\circ}C$ and pH 6~8. The optimum conditions for the production of antioxidant for carbon, inorganic nitrogen, and sodium chloride sources were 2.5%(w/v) dextrin, 0.5%(w/v) ammonium sulfate, and 2~6%(w/v) sodium chloride, respectively. The hydroxyl radical scavenging ability of Alteromonas sp. HJ-14 broth was 90.03%, which is higher than ascor-bic acid(83.28%) and lower than butylated hydroxyanisole(95.46%) and $\alpha$-tocopherol(97.17%).

We experienced a case of partial DiGeorge syndrome in a $35^{＋5}$ week premature female infant presented with micrognathia, fish-shaped mouth, beaked nose, nasal regurgitation, obstructive sleep apnea, velopharyngeal insufficiency and late onset hypocalcemic seizures. The chromosome 22q11 microdeletion was found by the FISH method. The lab findings showed serum calcium level of 4.4 mg/dL, ionized calcium level of 0.49 mg/dL, phosphorous level of 7.5 mg/dL, magnesium level of 1.3 mg/dL and PTH-RIA level of <1 pq/mL. Initial treatment was done with 10% calcium gluconate infusion and magnesium sulfate followed by oral calcium gluconate and low phosphorousformula milk feeding. The serum calcium level was normalized in 6 days. Nasal regurgitation, desaturation with obstructive sleep apnea continued. T-cell functions & numbers(CD 3, CD 4, CD 8)were decreased but Ig G/A/M levels were normal. No visible signs of thymus shadow were seen in either chest X-ray & chest MRI. Electrocardiography and echocardiography showed normal heart. Kidney ultrasonographby showed right side mild hydronephrosis. Neurosonography was normal but EEG showed electrical partial seizure. Hearing assessment by BERA showed mild to moderate hearing impairment. Velopharyngoplasty is scheduled for further treatment. A brief review of literature was made.

Glutaric aciduria type 1(GA1) is an autosomal recessive disorder of the lysine, hydroxylysine and tryptophan metabolism caused by the deficiency of mitochondrial glutaryl-CoA dehydrogenase. This disease is characterized by macrocephaly at birth or shortly after birth and various neurologic symptoms. Between the first weeks and the 4-5th year of life, intercurrent illness such as viral infections, gastroenteritis, or even routine immunizations can trigger acute encephalopathy, causing injury to caudate nucleus and putamen. But intellectual functions are well preserved until late in the disease course. We report a one-month-old male infant with macrocephaly and hypotonia. In brain MRI, there was frontotemporal atrophy(widening of sylvian cistern). In metabolic investigation, there were high glutarylcarnitine level in tandem mass spectrometry and high glutarate in urine organic acid analysis, GA1 was confirmed by absent glutaryl-CoA dehydrogenase activity in fibroblast culture. He was managed with lysine free milk and carnitine and riboflavin. He developed well without a metabolic crisis. If there is macrocephaly in an infant with neuroradiologic sign of frontotemporal atrophy, GA1 should have a high priority in the differential diagnosis. Because current therapy can prevent brain degeneration in more than 90% of affected infants who are treated prospectively, recognition of this disorder before the brain has been injured is essential for treatment.

Objectives : The purpose of this study is to investigate the effects of hot pepper extract and capsaicin on the adipogenesis in 3T3-L1 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods : Inhibiton of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 3 days in the absence or presence of hot pepper extract or capsaicin ranging from 0.01 to $1mg/m{\ell}$. The effects of hot pepper extract and capsaicin on adipogenesis were examined by measuring GPDH activity and by Oil Red O staining. Mature adipocytes from rat epididymal fat pad was incubated with hot pepper extract or capsaicin ranging from 0.01 to $1mg/m{\ell}$ for 3 hrs. The effects of hot pepper extract and capsaicin on lipolysis were examined by measuring free glycerol released. Fat tissue from pig skin was injected with hot pepper extract or capsaicinCFP ranging from 0.1 to $10mg/m{\ell}$ to examine the effects of hot pepper extract and capsaicin on histological changes under light microscopy. Results : The following results were obtained from present study on adipogenesis of preadipocytes, lipolysis of adipocytes and histological changes in fat tissue. 1. Hot pepper extract and capsaicin inhibited adipogenic differentiation at the concentration of 0.1 and $0.01mg/m{\ell}$, respectively, indicating that capsaicin was more effective in inhibiting adipogenesis than hot pepper extract. 2. Hot pepper extract and capsaicin decreased the activity of glycerol-3-phosphate dehydrogenase(GPDH) at the concentration of 0.1 and $0.01mg/m{\ell}$, respectively, indicating that capsaicin was more effective in inhibiting adipogenic differentiation than hot pepper extract. 3. Hot pepper extract and capsaicin increased glycerol release at the concentration of $0.1mg/m{\ell}$. There was no difference in lipolytic activity between hot pepper extract and capsaicin at the corresponding concentration. 4. Hot pepper extract and capsaicin caused shrinkage of fat cells, resulting in cell death at the concentration of $1.0mg/m{\ell}$, although capsaicin exerted this action over wide area than hot pepper extract. Conclusions : These results suggest that hot pepper extract and capsaicin efficiently inhibited adipogenesis, increased lipolysis of adipocytes and caused to shrink fat cells. Future studies are needed to make use of hot pepper extract pharmacopuncture for the treatment of obesity.

Objectives : The purpose of this study is to investigate the effects of Spirodelae Herba pharmacopuncture(SHP) on the adipogenesis in 3T3 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods : Inhibition of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3 preadipocytes were differentiated with adipogenic reagents by incubating for 3 days in the absence or presence of SHP ranging from 0.01 to $1.0mg/m{\ell}$. The effect of SHP on adipogenesis was examined by measuring glycerol-3-phosphate dehydrogenase(GPDH) activity and by Oil Red O staining. Mature adipocytes from rat epididymal fat pad was incubated with SHP ranging from 0.01 to $1.0mg/m{\ell}$ for 3 days. The effect of SHP on lipolysis was examined by measuring free glycerol released. Fat tissue from porcine skin was injected with SHP ranging from 0.1 to $10.0mg/m{\ell}$ to examine the effect of SHP onhistological changes under light microscopy. Results : Following results were obtained from the preadipocyte proliferation and lipolysis adipocyte and histologic investigation of fat tissue 1. SHP showed the effect of decreased preadipocyte proliferation on the high dosage($1mg/m{\ell}$). 2. SHP showed the effect of decreased the activity of glycerol-3-phosphate dehydrogenase (GPDH) on the high dosage($1mg/m{\ell}$). 3. Investigated the changes in lipolysis of differentiated adipocyte after treated SHP, we knew that these pharmacopuncture showed increasing the effect of lipolysis in all concentration significantly. 4. Investigated the histological changes in porcine fat tissue after treated SHP, we knew that these pharmacopuncture showed significant activity to the lysis of extensive cell membranes on high dosage($10.0mg/m{\ell}$). Conclusions : These results suggest that SHP efficiently induces diminishing proliferation of preadipocyte and lipolysis in adipose tissue.

For investigating the activities of algicidal bacteria, the variations of algicidal bacterial population and chlorophyll-a were checked weekly in Chindong Bay, Korea from May to July, 1998. For identifying their killing characteristics, three strains were selected from the isolated algicidal bacteria. The density of algicidal bacteria kept changing in the range of $6.0\times10^1$ to $6.4\times10^5$ cell $\ell^{-1}$. The density flux of algicidal bacteria coincided with that of chlorophyll-a by a week of lag time. Three algicidal bacteria isolated from field strains, H519S5-4, H605S5-15 and H605S5-22, were investigated in nine microalgal species, Heterosigma akashiwo, Chattonella sp. (Raphidlphyceae), Gymnodinium catenatum, Gyrodinium impudicum, Cochlodinium polyklikoides (Dinophyceae), Chaetoceros sp., Coscinodiscus granii, Ditylum brightwellii, Thalassiosira rotula (Bacillariophyceae). Strain H605S5-22 showed a wide algicidal activities over nine microlgae, strain H605S5-15 over H. akashiwo, G. catenatum, T. rotula, Chattonella sp. and strain H519S5-4 over H. akashiwo, Chattonella sp., Chaetoceros sp., G. catenatum. The activities of the three strains were detected by the secretion of algicidal substances. Therefore, it is suggested that the activities of algicidal bacteria have a significant influence over the population dynamics of phytoplankton and get involved with the sharp decrease in red tides in the coastal area.

Propionibacterium acnes have been recognized as pus-forming bacteria triggering an inflammation in acne. The present study was conducted to evaluate antimicrobial activities of Dryopteris crassirhizoma Nakai against these etiologic agents of acne vulgaris and application possibility as a cosmetic resource. D. crassirhizoma crude extract and hexane fraction was prepared and its anti-acne effect against Propionibacterium acnes was investigated with minimum inhibitory concentration (MIC) and paper disk diffusion method. The MIC of D. crassirhizoma crude extract and hexane fraction was 0.008 mg/mL and 0.001 mg/mL, respectively. This implies that D. crassirhizoma extract may be an efficient anti-acne ingredient for cosmetics, as a crude extract. The paper disk diffusion assay showed that its anti-acne effect was similar to that of triclosan. The cytotoxic effect of D. crassirhizoma extract was determined by a colorimetric MTT assay using HaCaT cell line and D. crassirhizoma extract exhibited lower cytotoxic effects. Finally, we examine the stability of D. crassirhizoma extract to temperature and pH. The D. crassirhizoma extract was very stable to high temperatures ($25{\sim}121^{\circ}C$) and to wide pH range ($pH\; 2{\sim}11$), suggesting its utilization for cosmetics.

Liquiritigenin and isoliquiritigenin are the major flavonoids present in licorice. These flavonoid compounds were prepared by submerged culture of Grifola frondosa (G. frondosa) HB0071 mycelia producing ${\beta}$-glucosidase in the aqueous extract of licorice. The contents of liquiritigenin and isoliquiritigenin were increased during the fermentation. This fungus produced a high ${\beta}$-glucosidase (activity of 91.5 mU/mL), thereby achieving high amounts of liquiritigenin and isoliquiritigenin ($568.5{\mu}g/mL$ and $89.6{\mu}g/mL$), respectively at 96 h. A reversed- phase high-performance liquid chromatography method was established for simultaneous determination of liquiritigenin and isoliquiritigenin in fermented licorice extract (FLEx). The anti-inflammatory activities were investigated by licorice extract (LEx) before and after fermentation with G. frondosa HB0071. The treatment of UVB-irradiated HaCaT keratinocytes with FLEx resulted in a dose-dependent decrease in the expression level of cyclooxygenase-2 (COX-2) mRNA. Furthermore, FLEx dose-dependently decreased mRNA of the pro-inflammatory cytokines of IL-$1{\beta}$ and IL-6 in UVB-irradiated HaCaT cells. These results suggest that FLEx may mitigate the effects of skin inflammation by reducing UVB-induced adverse skin reactions.

Objectives: This study was designed to investigate the analysis of apoptosis by Scirpi Tuber in Hela cell and MCF-7 cell. Methods: For cytotoxic effect of Scirpi Tuber extract, Scirpi Tuber extract were cultured on NIH3T3 cell in vitro. After treatment with various concentration of Scirpi Tuber, cell growth was evaluated in Hela cell and MCF-7 cell. Hoechst 33342 staining was performed to estimate DNA fragment effect of Scirpi Tuber on the apoptosis in Hela cell and MCF-7 cell. Annexin V/PI apoptosis assay was used to estimate the effects of Scirpi Tuber on the early apoptosis in Hela cell MCF-7 cell. All the stained cells were analyzed by a FACS. RT-PCR was used to estimate the apoptosis gene expression effect of Scirpi Tuber extract on Hela cell and MCF-7 cell. Results: Cytotoxic effect of Scirpi Tuber extract was not found on per NIH3T3 cell. The viability of Hela cell was significantly decreased Scirpi Tuber (500, $1000{\mu}g/m\ell$) in Hela cell 1day, 3day and 5days after treatment (p<0.01). The viability of MCF-7 cell was significantly decresed Scirpi Tuber ($1000{\mu}g/m\ell$) in MCF-7 cell (p<0.01), Scirpi Tuber ($500{\mu}g/m\ell$) in MCF-7 cell only 3days after treatment (p<0.01). In RT-PCR analysis, after treatment of $100{\mu}g/m\ell$ of ACR extract, BCL-2 were decreased and BAX, caspase-3 were increased both in Hela cell and MCF-7 cell. DNA fragmentation was observed the Scirpi Tuber on Hela cell and MCF-7 cell. As time goes on DNA fragmentation incresed. In Annexin V/PI apoptosis assay, after treatment of $1mg/m\ell$ of Scirpi Tuber, the early apoptotic cell increased both in Hela cell and MCF-7 cell. As time goes on apoptotic cell increased. Conclusion: Scirpi Tuber appears to have considerable activity on the apoptosis in Hela cell and MCF-7 cell.
