The effects of Obosan in the diet on growth, percent weight gain, specific growth rate, feed conversion ration and body composition of nile tilpia were investigated. First feeding fry average weighing 11.0 mg were fed the diets containing 0%, 0.25%, 0.5%, 1.0% and 2.0% Obosan for 7 weeks. Body weight, percent weight gain, specific growith rate of fish fed the diets containing 0.25%, 0.5% and 1.0% Obosan were significantly higher than control diet (P<0.05). Feed conversion ratio of fish fed the diets containing 0.25% and 0.5% Obosan showed best results compare to other experimental groups (P<0.05). Juvenile average weighing 281.0g and adult fish average weighing 563.0g were fed control and 0.3% Obosan supplemented diet for 30 days and 175 days, respectively. Body weight, percent weight gain and specific growth rate were significantly higher in the fish fed Obosan supplemented diet than control diet (P<0.05). Crude protein, crude lipid, crude ash and moisture of dorsal muscle and liver were not significantly different between two experimental groups.

Cannabidiol derivatives (1, 2 and 3), and 5-fluorouracil (4, 5-FU) were tested for their growth inhibitory effects against human oral epitheloid carcinoma cell lines (KB) using two different 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and sulforhodamine B protein (SRB) assay. These compounds showed a potent inhibitory activity in vitro in the micromolar range against KB cell lines. In general, the antitumor activity of these compounds (1, 2, 3 and 4) was in a dose-dependent over the micromolar concentration ranges from $1\;{\mu}M\;to\;100\;{\mu}M$. The comparison of $IC_{50}$ values of these compounds in tumor cell lines shows that their susceptibility to these compounds decreases in the following order: CBD > 5-FU > CBDME > CBDDE by the MTT assay and SRB assay. Cannabidiol derivatives (1, 2 and 3), and 5-FU were tested for their cytotoxic effects on NIH 3T3 fibroblasts using two different MTT assay and SRB assay. These compounds exhibited potent cytotoxic activities in vitro in the micromolar range against NIH 3T3 fibroblasts. In general, the cytotoxic activities of these compounds (1, 2, 3 and 4) were in a dose-dependent over the micromolar concentration range $1\;{\mu}M\;to\;100\;{\mu}M$. The comparison of $CD_{50}$ values of these compounds on NIH 3T3 fibroblasts shows that their susceptibility to these compounds decreases in the following order; CBD > 5-FU > CBDDE > CBDME by MTT assay, CBD > 5-FU > CBDME > CBDDE by SRB assay. These results suggest that cannabidiol (1, CBD) retains the most growth-inhibitory activity against KB cell lines.

The effect of exogenous phosphate supply on the regulation of phosphate metabolism was investegated during catabolic repression and catabolic derepression in yeast (Saccharomyces uvarum). As the results, when sugar was supplimented in cells cultivated under phosphate free, the growith rate was low but it was capable of cell division. Polyphosphate "B" was accumulated highly in proportion to amount of phosphate added to the medium. Without regard to phosphate supply of the medium, the total amount of polyphospgate was almost similar, although each polyphosphate was turned over. Activities of all phosphatases remained continuousoy high in the cells cultivated in the phosphate free medium. Especially under catabolic repression, the function of polyphosphate system was shown to compensate the ATP/ADP system as phosphate donor, energy source and regulator.

The experiment was carried out to examine on effect of ultrasonication on the growith of a mungbean while a mungbean is germinated and to measure amino acid content of a mungbean during its germination. Mungbean seeds soaked are divided into three groups; the first group was control group, untreated and naturally germinated. the second was ultrasonic treated group(UTG I), irradiated by ultrasonication for 8, 16 and 24min respectively immediately after soaking. the third was ultrasonic treated group(UTG II), irradiated by ultrasonication after 48hr germinating. The results were as foolows; Fresh weight, moisture, length of mungbean increased as its germination proceeds. while dry weight decreased. Ultrasonication tends to inhibit its germination of mungbean and results in the decrease in weight, length and moisture. Specially ultrasonication had a marked effect on UTG II. The longer the time of ultrasonication was, the more was the growth inhibited. In the control groups, the content of amino acid increased until 72 hours, but after that, it decreased. of the amino acid determined, glutamic acid decreased marekedly in the cotyledons, While the opposite was the case with aspartic acid in the hypocotyls. Comparing with the control groups, UTG I, the content of amino acid decreased. As the ultrasonic treaed time was increased, the concentration of amino acid in hypocotyl cotyledon tended to decreased. UTG II, the content of amino acid was lower than control groups, but higher than UTG I, and the effects of ultrasonication were similar to UTG I.

This study was carried out to investigate the effects of various kinds of commercial salts including Chunil, Hanju, Guwoon and Bamboo salts on the growth of microorganisms involved in kimchi fermentation. Among various microorganisms related to the kimchi fermentation, the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Pichia membranaefaciens and E. coli was examined. Based on the conditions of kimchi fermentation, 3% and 5% concentration of each salt were studied. Also, the temperatures at 1$0^{\circ}C$, 18$^{\circ}C$ and 37$^{\circ}C$ of the cultural condition were examined. The growth of Leuconostoc mesenteroides was inhibited depending on the reduction of cultural temperature and increase of concentration of salts. There was no considerable difference on the growth of Leu. mesenteroides in the different the kind of salts. However, the growth of Lactobacillus plantarum was strongly inhibited by the 5% concentration of Bamboo salt during incubation at 18$^{\circ}C$. When Lactobacillus plantarum was cultured at 1$0^{\circ}C$, its growth was remarkably decreased regardless of the kind and concentration of salts. In the case of Pichia membranaefaciens, Bamboo salt strongly inhibited its growth at all cultural temperatures. Apparent inhibitory effect on the growth of E. coli was observed by the Bamboo salt treatment during the incubation at 18$^{\circ}C$. At the cultural temperature of 1$0^{\circ}C$, similar results obtained.
