This is study was conducted to find out the effect of various plant hormones on the growth of garlic callus and to determine the effects of sulfur and nitrogen on the formation of alliin. The following results were obtained. The callus was grown effectively on the basal Linsmainer and skoog medium supplemented with 10-6M of kinetin and 2, 4-dichlorophenoxyacetic acid. When alliin produced by callus were extracted and identified by PPC allin appeared to have Rf value 0.21 in PPC which was exactly same as standard and it gave a deep red colar by Grot's reagent. The highest amount of alliin which is produced in callus culture was 270mg per 100g of dry weight in the basal Linsmaier and Skoog medium supplemented with 100% of NO3 as a nitrogen source.

the Chinese cabbage kimchi was fermented with the various submaterials such as hot pep-per garlic ginger leek green onion fermented anchovy juice and sugar according to the average contents of each submaterial described in the 39 kinds of references. And then the effects of each submaterial and lactic acid bacteria such as L. brevis. Leu. mesenteroides. P cerevisiae and L. plantarum on the content of carotenes were investigated, The major carotene in kimchi was $\beta$-carotene. And also $\delta$-carotene and $\alpha$-carotene were detected. Contents of $\beta$-carotene and total carotene were high in the kimchi containing leek red pepper powder green onion and fermented anchovy juice as a submaterial. But the kimchi containing or omitting the other submaterials were litter affected to the contents of carotene. Contents of $\beta$-carotene and total carotene were high in kimchi fermented with Leu. msenteroides L. brevis and P. cerevi-siae as a starter but was low with L plasntarum.

For this experiment frist the fermented Soybean Meju was prepared by domestic ordinary method of Korean and concentrated Meju suspensoidal extract was made for toxicological test sample on mice and rat. Even the oral dose of 10g extract per kg of mice had not any acute toxicity. So the median lethal dose(LOD50) is lilely to be much greatr or not to be. In comparison of the average weight gain rate for 4 weeks the control and test groups of 0.308g Ex/rat kg and 9.24g Ex/rat kg daily were the much the same as about 19% but 3.08g Ex/rat kg group waas exceptionally 2.7% higher than control For this period all test groups did not show any abnormality in appearance and anatomic findings. In serum GPT GOT alkaline phosphatase and blood urea nitrogen value there were no difference significantly between control and the test groups of 0.308g/rat kg and 3.08g/rat kg but 9.24g/rat kg group was some what higher than control. Especially in cholesterol alkaline phosphatase and blood urea nitrogen value 9.24g/rat kg group or 28days had 100mg/이 37.5u 32mg/이 respectively which were increased significantly. The pathological findings of all test groups especially 9.24g/kg group did not showed any characterized sign of acute or subacute liver damage or intestine lesion. So it is supposed that there is not any tocixants originated from some molds in fermented Korean domestic Meju which is prepared traditionally in winter.

this study is conducted to evalute the effect of ginseng fraction components(ginseng extract siolution; GES ginseng protein ; GP ginseng saponin ; GSA ginseng residue ; GR) upon hy-perlipidemia and fatty liver induced by high fat administration. In doing so the serum liver and epididymal adpoid tissue have been examined for lipid component level cortisol and insulin level. The change of liver tissue has been observed by light and electron microscope. In the cortisol level all experimental groups were lower compared to control group. The liver of rats observed histochemically. Control group appeared to be fatty liver but GP and GSA group looks normal electron-microscopically. GES and GP group showed a slight improvement compa-red with control group.

Properties of a protease purified from Neungee[Sarcodon aspratus(Berk, ) S. Ito] have been investigated. The enzyme displays a glycosylated serine protease. The enzyme is able to hydrolyze alanine glycine methionine glutamine and cysteine of N-CBZ and N-t-BOC-L-amino acid derivatibes relatively strongly but splits valine proline and isoleucine derivatives with low affinity which means the enzyme has the broad substrate spectrum toward the amino acids. Interestingly the enzyme was inhibited by bromelain inhibitor. That is the active site environ-ment of the enzyme is believed to be similar to that of bromelain However peptide mapping studies show that the two enzymes have distinct different cleavage sites.

The release of hepatic triglyceride lipase from cultured rat hepatocytes and its hormonal regulation were studied. The activity of lipase released into the medium in the presence of heparin was increasing during 24 hours on the 2nd of culture while this was 10% in the absence of heparin as compared with the lipase activity in the presense of heparin. When hepatocytes were cultured with anti-hepatic triglyceride lipase lgG the lipase activity was supp-ressed by 92% The results suggest that the enzyme relaeased into culture medium is identical to hepatic triglyceride lipase which can be released only in the presence of heparin the model of release being similar to that of lipoprotein lipase from adipocytes. The addition of monensin to the medium resulted in The inhibition of lipase secretion by 61% Insulin enhanced lipase activity only 20% whereas dexamethasone suppressed the activity by 44% These data inidica-ted that hepatic triglyceride lipase is secreted and released from hepatocytes in the presence of heparin and its secretion is regulated by hormones.

Physico-chemical properties including the composition of organic acids and fatty acids in native bee-honey and foreign bee-honey harvested in Kangwon area were studied with the emphasis on the honey which was collected form wild flowers nd mixed flowers sources for honey nectars. the major organic acids were considered as acetic acid formic acid and valeric acid in volatile acids and gluconic acid maleic acid malic acid quinic acid and citric acid in non-volatile fraction in both of native bee-honey and foreigr bee-honey. Some naturally occuring fatty acids({{{{ { C}_14{ } }}}}-{{{{ {C }_{20 } }}}}) were observed with the principal fatty acids of myristic aicd linolenic acid and palmitic acid and palmitic acid in the various honey, The characteristics of moisture content pH viscosity free acidity lactone and total acidity were also analyzed and discussed.

Studies comparing the relative effects of water soluble extract of Ganoderma lucidum kale juice and sodium dextrothyroxine on lipid component in liver brain and testis of hypercholeste-rolemic rats for 4 weeks. Therefore the aim of this work was to investigate for prevention in cardiovascular disease, Total cholesterol concentration in liver were significantly lower kale juice and sodium dextrothyroxine(1.25mg/kg diet) fed groups than the other groups and trigly-ceride concentration was significantly lower Ganodrma lucidum fed group than in control group;. Total cholesterol concentration in testis were lower other groups than in control group and triglyceride concentration were significantly lower cholesterol Ganoderma lucidum and kale juice groups in control group. Phospholipid concentration in testis was higher sodium dextroth-yroxine fed group thanin control group.

The purpose of this survey was to study Nutrition Status related to eating behabvior health status and nutrient intake. this survey was conducted for 100 students at Mokpo National University from semptember 25 to 29 in 1989. Average height and weight of students were found to be increased for last thirty years from 1957 to 1989. the average height of male and female were 172.0cm 160.1cm and the average weight of those were 63.4kg 48.2kg respectively. Health status showed fair. but most of students had symptoms such as stress cold and disorder of stomach. The main purpose of eating is to satisfy hungry and routinal work. Most students have had dietary problems such as irregularity of meal time and skipping meal. Most nutrients was intaken properly but some were under percentae of RDA. For the male the average intake of Calorie(84.5%) and Vitamin B2(93.3%) were lower than RDA for the frmale that of Calorie(81.7%) and Iron(80.6%) The ration of percent calorie of Carbohyd-rate : Protein : Fat from total calories in male was 65:15:20 and that of female was 64 : 15: 21 this result was properly approached to the Recommend Calorie Composition(Based on Recommended Allwances 5th ed. Korea FAO Assoc. 1989)

This study was designed to obseve the effect of defatted perilla as a dietary fiber on lipid components of serum feces and liver in rats. Serum cholesterol and triglyceride were signfican-ly decreased in defatty perilla added groups. total lipid cholesterol and triglyceride of feces were significantly increased in defatted perilla added groups. Liver phospholipid content was higher in the defatted perilla added groups. The other lipid components of the liver were not affected by the defatted perilla administration. These results suggest the possibitlity that defatted perilla have a reducing effect of serum cholesterol and triglyceride through the incre-ment of feacal excretion of lipid component and phospholipid in liver.
