The lipid lowering and antioxidant effects of Gansoo(BL18), Pungji(GB20) and Eumnungcheun(SP9) acupuncture in rats fed high fat diet were analyzed in biochemical and molecular biological aspects. The results obtained from this study are as follows : 1. In the body weight reduction, all acupuncture groups showed a high reduction compared to those of control group and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high reduction. 2. The concentration of plasma triglyceride, total cholesterol and LDL-cholesterol with acupuncture groups showed a little decrease and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) groups showed a low values compared to those of other acupuncture groups. However, the tendency of HDL-cholesterol concentration showed no significant different. 3. The concentration of plasma ${\beta}-lipoprotein$ and free fatty acids showed a lowest values in the Gansoo(BL18) and Pungji(GB20) acupuncture groups and the glucose concentration showed to decrease in all treated acupuncture groups. 4. The concentration of liver total cholesterol and triglyceride in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control group. 5. In all the acupuncture groups, the plasma glutamic oxaloacetic transaminase(GOT) activity showed a little decrease. In the glutamic pyruvate activity(GPT), Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control groups. However the values of eumneungcheun acupuncture only group showed no significant difference to those of control group. 6. The plasma and liver Thiobabituric acid reactive substance (TBARS) concentration in Gansoo(BL18) and Pungji(GB20) acupuncture groups were a lower than those of control group. However the values of eumneungcheun acupuncture group showed no significant difference to control group. 7. The superoxide dismutase (SOD) activity in Gansoo(BL18) acupuncture group and Glutathione peroxidase (GSH-Px) activity in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high values. The catalase (CAT) activity in all the acupuncture groups showed a higher values than those of control group. 8. In acupuncture groups, DNA expression of Apo-B and Apo-E showed a tendency to decrease, however DNA expression of leptin showed no significant difference in all treatment groups. DNA expression of $TNF-{\alpha}$ showed a increase in acupuncture groups. These results indicate that Gansoo(BL18) and Pungji(GB20) (especially Gansoo(BL18)) acupuncture affect the lipid metabolism and showed possibility of lowering adipose tissue mass and lipid peroxidation.

The time, yield, and related genes expression of PHB accumulation of Acidiphilium cryptum DX1-1 were investigated under four different initial C/N ratios, 1.2, 2.4, 7.5, and 24. The results of time and yield of poly-$\beta$-hydroxybutyrate (PHB) accumulation show that the initial C/N ratio of 2.4 was optimum for strain DX1-1 to accumulate PHB, but both higher and lower initial C/N ratios did not favor that process. Based on the genome of Acidiphilium cryptum JF-5, 13 PHB accumulation related genes in strain JF-5 were chosen and successfully cloned from strain DX1-1. The differential expressions of the 13 functional genes, in different C/N ratios as cited above, were then studied by real-time PCR. The results show that all the 13 genes were most upregulated when the initial C/N ratio was 2.4, and among which the gene Acry_3030 encoding poly-$\beta$-hydroxybutyrate polymerase and Aery_0626 encoding acetyl-CoA synthetase were much more upregulated than the other genes, which proved that they play the most important role for PHB accumulation, and acetate is the main initial substance for PHB accumulation for strain DX1-1. Potential regulatory motifs analysis showed that the genes related to PHB accumulation are regulated by different promoters and that the motif had weak similarity to the model promoters, suggesting that PHB metabolism in Acidiphilium cryptum may be mediated by a different mechanism.

The ethanol extract of Dryopteris crassirhizoma Nakai showed strong growth inhibition against 5 strains of Listeria monocytogenes at the concentrations of $100{\sim}500$ ppm and the minimum inhibitory concentration of n-hexane fraction was under 50 ppm. The D8-2-5 fraction isolated from n-hexane fraction of Dryopteris crassirhizoma Nakai showed a strong bactericidal activity on 5 strains of L. monocytogenes at 20 ppm level in tryptic soy broth medium. At the level, the viable count was reduced $4{\sim}6$ log cycle compared to initial cell number. Observation by the measurement of adenosine triphosphate (ATP) contents and transmission electron microscope showed that disruptions of the cell wall and elution of intracellular ATP are assumed to be due to the bactericidal activity. In addition, the n-hexane fraction of Dryopteris crassirhizoma Nakai showed the strong growth inhibitions at 50 ppm on Vibrio parahaemolyticus and Bacillus cereus, and at 25 ppm on Staphylococcus aureus.

Sarcopenia, a geriatric and multifactorial syndrome characterized by progressive systemic skeletal muscle disorder, may be associated with many comorbidities. Sarcopenia caused by a decrease in muscle mass and muscle strength is accompanied by the aggravation of various pathological conditions, and as life expectancy increases, its prevalence will continue to increase in the future. During the aging process, chronic oxidative stress and increased inflammatory responses act as major contributors to skeletal muscle loss. In addition, disruption of autophagy and apoptosis signals associated with dysfunction of mitochondria, which are essential for energy metabolism, accelerates the loss of muscle proteins. The pharmacological effect of cordycepin, a major physiologically active substance in the genus Cordyceps, which has been widely used for the prevention and treatment of various diseases for a long time, is directly related to its antioxidant and anti-inflammatory actions. In this review, we present the correlation between apoptosis, autophagy, protein catabolism, and satellite cell activity important for muscle regeneration using cordycepin for the prevention and treatment of sarcopenia. Although there have been few studies so far on the use of cordycepin for sarcopenia, previous studies suggest that cordycepin may contribute to inhibiting the age-related weakening of mitochondrial function and blocking the breakdown of muscle proteins. In addition, the protective effect of cordycepin on muscle cell damage is considered to be closely related to its antioxidant and anti-inflammatory activities. Therefore, it is considered that more continuous basic research is needed, focusing on the molecular biological mechanism of cordycepin, which is involved in the anti-aging of muscle cells.

The poxvirus group is considered to be a typical cytoplasmic inclusion forming virus. Every poxvirus has been reported to produce only one kind of inclusion in the infected tissues. A vague concept that inclusions of poxviruses are eosinophilic or acidophilic has prevailed. Although many papers and theories about the nature of the inclusion have been presented, most of them are not quite convincing on the point of the relations with virus multiplication, and an analysis of papers published showed that there seem to be many discrepancies in the descriptions of the nature of the poxvirus inclusions. Comparative studies on host-virus interaction with cowpox, orf, swinepox and fowlpox viruses which selected from each Group (I-IV) of poxviruses were performed from the morphological and virological standpoints. At first, in cowpox virus-FL cell system, as a comparative model, cytoplasmic inclusion, nucleic acid metabolism by autoradiography and detection of viral antigen by immunofluorescence were studied and obtained the results as follows: 1. The focus-like cytopathic effect (CPE) at early stage developed to entire culture at terminal stage of infection, and also the developing status of CPE was correlated to viral doses for inoculation. Two kinds of cytoplasmic inclusions which named A and B type were easily observed by Giemsa, hematoxylin-eosin (H & E) and May-Greenwald Giemsa (MGG) stainings in the infected cells. The B type inclusions were formed at early stage of infection and the A type inclusions were produced subsequently the B type formation. The B type which common type inclusion in poxviruses was a small compact or aggregate at early stage and developed to a large diffuse body at terminal stage of infection. On the other hand, the A type inclusion which depend upon the kind of virus was appeared as round and discrete shape, and its size and number was increased gradually during the culture period. It was characteristic to form distinct halos around the both types of inclusions in acid fixed, H & E stained preparations of infected cultures. The B type inclusion was always positive in Feulgen reaction and showed as DNA containing body but the A type inclusion was not. 2. In the relationship between inclusion and DNA metabolism of infected cells by the qualitative autoradiography using 3H-thymidine, the appearance of silver grains was coincided with B type inclusion but not with A type inclusion. This showed that the DNA synthesis was proceeded in all B type inclusions except those in the terminal stage with a diffuse form. This suggested that the B type inclusions are only sites of DNA synthesis and this was proceeded after the cell infection independently. The activity of DNA synthesis of the inclusions was nearly the same as that of the nucleic of normal cells and non-inclusion bearing cells. and non-inclusion bearing cells. Regardless of the size of the degree of DNA synthesis of the B type inclusion, inclusion bearing cells all showed remarkable suppression of nuclear DNA synthesis. 3. By the direct fluorescent antibody technique viral antigen in infected cells was detected. The B type inclusions have been proved to contain a great deal of viral antigen, whereas the basic substance of A type inclusion did not show antigenicity except the round edge. It was suggested that the round edge fluorescence might be caused by the glare of cytoplasmic viral antigen which pushed out and concentrated by the A type inclusion development. 4. Hemorrhagic red pock formations on chorioallantoic membrane of embryonated chicken egg had proved the characteristic of used viral strain. 5. By the above studies on the nature of two types of inclusions and the role they play in virus multiplication, it was concluded that the B type inclusion must be the site of the synthesis of viral DNA and protein as well as the site of the virus.

The effects of orally administered Seomaeyakssuk (Artemisia argyi H.) vinegar on lipid metabolism in Sprague-Dawley rats fed a high-fat and high-cholesterol (HFC) diet were analyzed. The experimental animals were divided into five groups: a normal diet group (normal, N), HFC diet group (control, C), HFC diet with lovastatin at 20 mg/kg body weight (B.W.) group (positive control, PC), HFC diet with malt vinegar group (TM), and HFC diet with Seomaeyaksuk vinegar group (TS) (2 mL/kg B.W.). After 4 weeks of feeding rats the experimental diet, contents of serum total lipids and total cholesterol levels of TM and TS groups were significantly lower than those of the PC group. Triglyceride contents of the TM and TS groups were not significantly different from those of the PC group but significantly lower than those of the C group. Content of serum high density lipoprotein-cholesterol was significantly lower than that of the N group but higher than that of the C group. Low density lipoprotein-cholesterol content of serum was 190.68 mg/dL in the TS group, which was the lowest except for the N group. Aspartate transaminase and albumin transaminase activities as a measurement of liver damage index were not significantly different between the TM, TS, and C groups. Serum thiobarbituric acid reactive substance content of the TS group was reduced to a similar level as the N group but was lower than that of the C group in the liver and significantly higher than that of the N group. Antioxidant activity of the TS group was 55.69% in serum, which was a similar to that of the N group, and was 52.39% in the liver, which was not significantly different than that of the C group. From these results, we conclude that Seomaeyakssuk vinegar improves serum lipid content as a result of the complex action of vinegar, an active ingredient of Seomaeyakssuk and a product of the fermentation process.

The sterile phenomenon is frequently found in the inter-species hybrids of ginseng as in other plants. It is known that among the hybrids between Panax Ginseng (PG) and Panax Quinquefolium (PQ), and between Panax Ginseng and Paxax Japonicus (PI), PG${\times}$PI is fertile only very rarely, while PG ${\times}$ PQ is always sterile. Therefore, in order to clarify the relationship between this sterility phenomenon and the metabolism of free amino acids, the changes of free amino acids through the formation of the flower organs and seeds of two hybrids, PG ${\times}$ PQ and PG ${\times}$ PI were investigated by thin layer chromatography. The results are summarized as follows: 1. Distinct differences in the quantity and number of free amino acids were recognized between PG ${\times}$ PQ, PG ${\times}$ PI and their parent plants. From the hybrid PG ${\times}$ PQ, 19 kinds of ninhyrin sensitive substances were detected in all. They were (1) 17 amino acids: alanine, valine, leucine, phenylalanine, proline, hydroxy-proline, serine, threonine, tyrosine, aspartic acid, glutamic acid, lysine, arginine, ${\gamma}$-amino butyric acid, ${\beta}$-alanine, cysteic acid and tryptophan, and (2) two amides: asparagine and glutamine. From the hybrid PG ${\times}$ PI, in addition to the above 19 substances, methionine and one unknown substance were detected. 2. Generally, alanine, as partie acid, glutamic acid, cysteic acid and asparagine were detected in large amounts in the two hybrids as in PG, PG and PJ but it was a noticeable fact concerning these two hybrids that the largest quantity of asparagine was found at microspore satge and pollen mature stage. 3. The decrease of cysteic acid in the two hybrids at the red ripened stage was the same as in PQ and PJ but opposite to the change in PG. The detection of methionine in PG ${\times}$ PJ was worthy of notice. 4. The change of proline was conspicuously different from that in their parent plants. It was detected as a trace of color at the micros pore stage while asparagine was detected in the greatest amount at that time. It is well known that the quantity of proline is closely related to the sterility of plant. This fact was also found true in the formation of ginseng seeds. It was reported as well that asparagine accumulated when proline decreased. 5. The deficiency of proline seemed to be closely related with the sterility of hybrids and with the degradation of pollen in anther. 6. The difference in the changes of free amino acids between the selfed lines of PG, PQ and PJ, and their hybrids seemed to be caused by the transformation of gene-action system by hybridization. On these phenomena along with proline metabolim and its physiological role in seed formation further studies are required.

As a result of analyzing the change of material substance of all sorts biochemically and comparing the control with ${\gamma}$-ray irradiation (800${\gamma}$, 40 Min), incubating the silkworm eggs (Bombyx mori L.) as the objective in the process of growth of embyro shortly before hatching, the following conclusion has been found. 1. Ascorbic acid has shown the maximum increase of 319 r/g in the Byong B embyro stage and in other words it has increased during the period of vigorous metabolism of the materials in eggs but it has decreased before hatching after that period. 2. Triglyceride has shown the increase of 27.54 mg/g in the Byong A stage, the early period of incubation and in other words it has increased in the period of activation of cells in eggs but it has gradually decreased during the growth of embyro after that period. Great change of either total cholesterol or free cholesterol has not been shown from the early period till shortly before hatching. 3. Free fatty acid has shown the minimum decrease of 257.4$\mu$ mole/g in the Byong A stage in which triglyceride increases greatly. On the contrary, it has shown the increase of 1, 020.0$\mu$ mole/g in Ki A stage in which triglyceride decreases. As a whole, the fact that free fatty acid increases according to the growth of embyro in eggs has been found. 4. Glucose has shown the increase of 281.2 mg/g in control during tile Pigment stage and it has shown the increase of 179.6 mg/g in ${\gamma}$-ray irradiation during the same period. The difference in quantity between the former and the latter is due to the fact that the growth of embyro has been influenced by the radio active. Glucose has changed with free fatty acid and phosphorus the other way round. 5. Control organic phosphorus has shewh the increase of 5.23mg/g during the Byong B or Ki A in which organ and tissue in the emhyro has been formed. Organic phosphorus in ${\gamma}$-ray irradiation has shown the increase of 5.73mg/g during Ki B. Inorganic phosphorus has shown only a little change in the control and ${\gamma}$-ray irradiation. The phosphorus in both has shown a little quantity in the ${\gamma}$-ray irradiation in the early period of incubation. After the Ki A embyro, it has increased rapidly and it has increased till the hatching more continually than in control. The about results of the research will be helpful and instructive to the betterment and improvement, breeding and management of animals and plants.

The effects of freeze-dried powder from fresh and black garlic hot water extracts on the lipid metabolism in Sprague-Dawley rats fed a high-cholesterol diet were analyzed. The experimental group was classified into the normal group (NG), the high-fat (HF) and high-cholesterol diet group (CG), the HFC and 1% fresh garlic hot water extract powder-added diet group (FGEG), and the HFC and 1% black garlic hot water extract powder-added diet group (BGEG), respectively. The serum total lipid content was 381.52±7.30 mg/ml and 368.80±4.40 mg/ml in the FGEG and the BGEG, respectively, and was significantly lower than that of the CG. The total cholesterol and triglyceride contents of the FGEG and BGEG were also significantly lower than that of the CG. The high-density lipoprotein (HDL) cholesterol was significantly higher, and the low-density lipoprotein (LDL) and the very low-density lipoprotein (VLDL) cholesterol content was lower in the FGEG and BGEG than in the CG. The serum ALT and AST activities were significantly lower than those of the CG, and especially the BGEG was lower. The total cholesterol content and the triglyceride levels of the liver tissue were 36.0% and 14.3% lower in the BGEG than in the CG, respectively. The thiobarbituric acid reactive substance (TBARS) concentrations in the serum and the liver tissue were higher in the CG than in the FGEG and BGEG, but there was no difference between them. Based on these results, garlic extract powders significantly reduced the lipid profile and increased the antioxidant activity in rats in vivo. The black garlic hot water extract powder was more effective than raw garlic because of the total number of phenolic compounds and browning substances in the black garlic.
