In order to achieve repetitive somatic embryogenesis in cacao (Theobroma cacao L.), callus derived from floral tissues were continuously cultured in a medium containing 2,4-D. In 5% of the explants, repetitive somatic embryogenesis was observed after 8 weeks and maintained in a globular stage for several weeks. This is the first report showing repetitive somatic embryogenesis in cacao. The calli were bombarded with a plasmid containing $\beta$-glucuronidase (gus) as reporter gene. Two week old calli showed the high average number of cells expressing the us gene. The effect of osmotic agents (mannitol, sorbitol and sucrose) on gene expression was evaluated. Pre-treatment during 16 h with 0.25 M mannitol revealed an improvement in gene expression. The potential utilization of the repetitive embryogenesis, combined with osmotic treatment, is discussed as an alternative to achieve stable transgenic cacao plants.

Galectin-3 is a ${\beta}$-galactoside-binding lectin that plays a role in neuroinflammation through cell migration, proliferation, and apoptosis. In the present study, regulation of galectin-3 was examined in the brain of mice infected with the Daniel strain of Theiler's murine encephalomyelitis virus (TMEV) at days 7 and 81 post-infection by immunohistochemistry. Immunohistochemistry revealed that galectin-3 was mainly localized in ionized calcium-binding adapter 1-positive macrophages/activated microglia, but not in Iba-1-positive ramified microglia. Galectin-3 was also weakly detected in some astrocytes in the same encephalitic lesions, but not in neurons and oligodendrocytes. Collectively, the present findings suggest that galectin-3, mainly produced by activated microglia/macrophages, may be involved in the pathogenesis of virus induced acute inflammation in the early stage as well as the chronic demyelinating lesions in Daniel strain of TMEV induced demyelination model.

The purpose of this thesis was to understand the various kinds of Korean liquors. To do this, about fifty different kinds of liquors and wines presented in Yi-dynasty literatures were reviewed and classified into several categories. The findings of the study are as follows, 1, Liquors of Yi-dynasty can be classified into three groups; Chungju or Takju which is brewed from rice or glutinous rice, Jeungryuju(Soju) which is made by distillation of Chungju or Takju, and Hwahyangju that is made by addition of fruits, fragrance, or medicinal plants in Chungju, 2. The basic method of making these liquors is in general to make yeast first and fix a liquor base by mixing rice or glutinous rice and yeast, and then add more rice or glutinous rice into the liquor base, and finally ferment the mixture for certain periods. On fixing a liquor base, several methods of rice preparations were used; these were white rice cake, rice paste, boiled dough of rice powder, and steamed rice. 3. Duration of fermentation was in general one to three weeks. However, the shorter one was completed within 3 days and the longer one required even one year or more. 4. Of Hwahyangju the ones with medicinal plants can be divided into several groups according to their medical effects; wines for mental and emotional stability, making blood and active circulation, increase in body stamina, promoting health and living long-life, treatment of stomachache and bruise, and enhancement of the functions of body organs, especially eyes ana ears.5. These liquors and wines above were brewed for daily use or special occasions (Sesiju).

In the previous work(Kim et al, 1973), the quality of sun-dried Alaska pollack, Theragra chalch-ogramma, was discussed in the aspect of non-enzymatic discoloration as a function of relative humidity during storage at room temperature($20^{\circ}C$). In this paper, sun-dried squid, Ommastrephes steam pacificus was investigated at the same aspect mentioned above. Fresh squid from the whole sale market was dressed, filleted, dried for 48 hours in the open air and finally stored in the humidistat chamber. Lipid oxidation ana development of non-enzymatic browning were tested by the same methods described in the previous paper. The TBA value showed a maximum peak on 30 day storage, hereafter tended to decrease gradually. The rate of browning, however, in water soluble fraction as well as in chloroform-methanol fraction was lower at 0.34 to 0.45 water activity than at any other case, and propagation of lipid oxidation was also diminished at the above level of water activity. From the results, it is recognized that storage at Aw=0.34 to 0.45 provides higher quality stability for sun-dried squid.

Graft copolymerization of methlymethacrylate(MMA) onto sodium alginate(SA) aqueous solution by sodium metaperiodate$(NaIO_4)$ as an initiator was carried out with the variation of the reaction time, the reaction temperature and the concentrations of initiator and monomer. The results obtained were as follows: 1. SA was easily separated from the reaction mixture of homopolymer, graft polymer and sodium alginate ungrafted by the treatment of concentrated boiling $Na_3PO_4$, solution with the small amount of $Na_2SO_3$ to the mixture and then isolated as the acid form by acidifying the salts solution containing SA. 2. The amount of graft polymer was larger than that of homopolymer below $70^{\circ}C$ whereas above $70^{\circ}C$ the amount of homopolymer was larger. 3. The sum of each amount of graft polymer ana homopolymer was always increased with increase of the reaction time, the reaction temperature and the concentrations of initiator and monomer. 4. With increase of the concentration of initiator, the graft efficiency was increased below $70^{\circ}C$ while decreased above $70^{\circ}C$. 5. Graft copolymerization of MMA onto SA in aqueous solution was carried out without initiator.

A newly-isolated thermophilic strain of the zygomycete fungus Rhizomucor pusillus 13.36 produced highly active dextrinogenic and saccharogenic enzymes. Cassava pulp was a good alternative substrate for amylase production. Dextrinogenic and saccharogenic amylases exhibited optimum activities at a pH of 4.0-4.5 and 5.0 respectively and at a temperature of $75^{\circ}C$. The enzymes were highly thermostable, with no detectable loss of saccharogenic or dextrinogenic activity after 1 hand 6 h at $60^{\circ}C$, respectively. The saccharogenic activity was inhibited by $Ca^{2+}$ while the dextrinogenic was indifferent to this ion. Both activities were inhibited by $Fe^{2+}\;and\;Cu^{2+}$ Hydrolysis of soluble starch by the crude enzyme yielded $66\%$ glucose, $19.5\%$ maltose, $7.7\%$ maltotriose and $6.6\%$ oligosaccharides.
