Distribution of the proteolytic activities of crude pretense extracted from the viscera of ten kinds of fish was examined. Their proteolytic activities on proteinous substrates (azocasein, hemoglobin, and casein) from the viscera of anchovy, bastard flatfish, mackerel and red sea bream were higher than those of other fishes, and the crude pretenses were further fractoinated with acetone or ammonium sulfate. Optimum concentrations for pretenses fractionation were $0\~55\%$ for acetone and $30\~70\%$ for ammonium sulfate. The fractionated viscera pretense of mackerel showed the highest proteolytic activity among four kinds of fishes. Activities of cathepsin D- and pepsin-like enzymes at pH 3.0, cathepsin L-, B-, H- and G-like enzyme at pH 6,0, and Hypsin- and chymotrypsin- like enzymes (pH 8.0) were detected in the fractionated viscera pretense, whereas activities of cathepsin L- and chymoeypsin-like enzyme were observed in commercial pretenses. Proteolytic activities of Alcalase, Protamex, and Aroase AP-10 for azocasein were slightly higher than the fractionated viscera pretenses, but their amidolytic activities at pH 6.0 and 8.0 toward synthetic substrates were lower than counterpart. The fractionated pretenses from fish viscera would be utilized as commercial pretenses.

Objectives : The paper attempted to analyze the contents found in the networks of five viscera in Yixuerumen's Zangfutiaofen published by Li Chan in 1575, and tried to reveal the body structure dealt in the contents through anatomical verification. Methods : Books such as Huataxianshengneizhaotu, Tushupian, and Shisijingfahui were used to compare, understand, and interpret the original texts and annotations of Yixuerumen in an attempt to verify these through anatomy reference texts and computer programs. Results : In Yixuerumen, some contents of the networks of five viscera were revised to see feixi as not one but two, and explained the relationship of intestinal organs through heart and lung. Anatomically speaking, the networks of five viscera has a vertical structure that unfolds top to bottom centering on aorta, and has many organs connected to it such as trachea, esophagus, splenic artery, pulmonary trunk, ureter, mesentery arteriovenous, gonadal artery, and ductus deferens. Conclusions : The networks of five viscera has a great significance in that it is the fruit of much efforts where oriental medicine tried to explain not only the functions of five viscera, but also the creation and circulation of qi, blood, and bodily fluids through anatomical observation.

The purpose of this thesis is to show the historical context of tongue-viscera correspondence scheme based on as wide investigation as possible. For this purpose, we collected and investigated 35 books related to tongue diagnosis. As a result, we faound the following: There were some tentative trials to associate viscera or viscera meridians with tongue areas since shown in the Effective formulae of inherited medical works (世醫得效方, 1337). The main stream of tongue-viscera correspondence scheme was the form in which the apex, the center, and the root of tongue are associated with Heart, Spleen (and Stomach), and Kidney. On the viscera correspondence to the sides of tongue, there had been two streams. The first one is originated from the Upper-most Book on Shanghan (傷寒第一書, 1780), in which the sides of tongue are assumed to be associated with Liver and Gall-bladder. The second one is originated from the Ikeda Family's Chant on the Tongue (池田家舌函口訣, 1807), in which the left side and the right side of tongue are assumed to be associated with Liver and Lung separately. The former type have been accepted as the standard form in modern traditional Asian medicine education. In addition to the above types, three other correspondence schemes were also existed, but have disappeared now. These days, some new correspondence schemes are being suggested based on new approaches.

Objective : By establishing the Five Viscera Source Point Acupuncture as the targeted acupuncture treatment for stadardization, as the first step, this study was conducted to sort the indications of each acupuncture remedies, which can be referred as one of the most important factors in acupuncture treatment, based on Yeoungchu. Method : This study selected only the contents related to indications of five viscera, by extracting the relevant sentences from Yeoungchu using the search words Liver(Liver Meridian, First Yin), Heart(Pericardium, Heart Meridian, Second Yin), Spleen(Spleen meridian, Third Yin), Lung(Lung Meridian, Third Yin), and Kidney(Kidney Meridian, Second Yin). Result & Conclusion : 1. We selected and extracted text related to liver disease from Chapter 16, heart (pericardium) disease from Chapter 16, spleen disease from Chapter 19, lung disease from Chapter 17, and finally kidney disease from Chapter 17 of Yeoungchu. 2. The basic theory of applying Five Viscera Source Point Acupuncture to five viscera diseases is first assorting the diseases according to its state (i.e. deficiency or excess), then draining the source point of the appropriate viscus in case of excess, or supplementing the source point of the appropriate viscus in case of deficiency. 3. For the correct application of Five Viscera Source Point Acupuncture, the classification of the disease, not only the judgement on its state, must be presented systematically and synthetically in combination with Four Examinations. Therefore the follow-up studies needs to be conducted.

For the effective utilizing of polyunsaturated lipids in filefish viscera wasted from marine manufactory the conditions of degumming, deacidification, decoloring and deodorization for the processing of refined viscera oil were investigated. In the process of refining degumming with 20$m\ell$ of 4% oxalic acid per 100$m\ell$ of crude filefish viscera oil resulted in the lowest residual phosphorus content as 115.8 ppm and optimal condition to neutralize the filefish viscera oil was treating for 30min at 60$^{\circ}C$ with 0.5% excess of 4M sodium hydroxide solution. Decoloring was optimized by adding 10% bleaching earth and treating for 20min at 60$^{\circ}C$ under vacuum, and deodorizing was done by steam distillation at 180$^{\circ}C$ under 4 torr of vacuum.

For the effective utilization of skipjack tuna viscera, a study was carried out to investigate the applicability of viscera protein hydrolysate (VPH) as a protein supplement in the processing of imitation sauce and bread. The optimum extraction and hydrolyzation conditions for the production of viscera protein concentrate (VPC) and viscera protein hydrolysate (VPH) were determined. Boiled viscera could be extracted by ethyl alcohol without significant deterioration as a raw material for the further processing. High quality of VPH could be obtained by hydrolysis with 1% pepsin under its optimum condition $(pH\;1.65,\;37^{\circ}C)$. The solubilities of VPC and VPH were 40% and 90%, respectively, and the essential amino acid contents in two products were 48.7% and 63.2%, respectively. Especially, the content of taurine, a physiologically important amino acid, was 9.4% in VPH. In experimental preparations of imitation sauce and bread, panel test showed that the supplementation of 10% of VPH in imitation sauce and $3{\sim}5%$ of VPH in bread was well accepted in sensory characteristics such as color, flavor, taste and texture.

Phospholipids were recovered from squid viscera residues by ethanol extraction after supercritical carbon dioxide($SCO_2$) extraction and from squid viscera was not processed $SCO_2$ by various organic solvent extraction. $SCO_2$ extraction were performed at $45^{\circ}C$ and 20 MPa for removal of non polar lipid molecules from freeze dried squid viscera sample. Phospholipids were extracted from freeze dried squid viscera sample by chloroform, hexane, methanol, and ethanol and from $SCO_2$extracted squid viscera sample by ethanol. The pH was fixed at 5.7 for all phospholipids extraction conditions. Phospholipid classes were analyzed by HPLC equipped with evaporative light scattering detector (ELSD). Phosphatidyl choline(PC) extracted by ethanol from $SCO_2$ extracted residues was higher than that of extracted by ethanol from squid viscera. But phosphatidyl ethanolamine(PE) and phosphatidic acid(PA) were extracted higher percentage in raw squid viscera. The fatty acid compositions in phospholipids extract by ethanol extract from $SCO_2$ extracted residues were analyzed by gas chromatography(GC). Docosahexanoic acid(DHA) was found in highest percentage in phospholipid extract.

Ruminal degradation characteristics and intestinal availability of crude protein (CP) in four animal-origin feeds (fish meal, meat meal, viscera meal, feather meal) were estimated by mobile nylon bag technique. Three ruminally and duodenally cannulated Holstein dairy cows (average body wt. 550kg) fed a diet containing 40% concentrate and 60% orchard grass hay on a dry matter (DM) basis. Assuming that the outflow rate of diet in rumen is 5% per hour (k =0.05), contents of quickly degradable CP (QDP), slowly degradable CP (SDP), and undegradable CP (UDP) in the rumen were 27.6%, 9.4%, 63.0% for fish meal, 34.3% 28.1%, 37,6% for meat meal, 43.9%, 12.5%, 43.6% for viscera meal, and 14.4%, 15.8%, 69.8% for feather meal, respectively. Intestinal CP degradability was 51.0% for fish meal, 27.2% for meat meal, 37.9% for viscera meal and 56.2% for feather meal. Available UDP in the intestinal tract was contained 288 g, 217 g, 246 g and 423 g per kilogram DM of diet in fish meal, meat meal, viscera meal and feather meal, respectively.

Supercritical carbon dioxide extraction was investigated as a method for removing lipids and bad flavor from tuna viscera. To find the optimum conditions, different experimental variables, such as pressure, temperature, flow rate of solvent and sample size, were evaluated for the effective removal of lipids and the undesirable smell. Ethanol was used as the entrainer, with a $3\%$ by vol $CO_2$ flow rate. By increasing the pressure at constant temperature, the efficiency of the lipid removal was improved and the protein was concentrated without denaturalization. The main fatty acids extracted from the tuna viscera were palmitic acid (16:0), heptadecanoic acid (17:1), oleic acid (18:1) and docosahexaenoic acid (22:6). The major amino acids in the tuna viscera treated by supercritical carbon dioxide were glutamic acid, leucine and lysine, and the free amino acids were L-proline, taurine and L-$\alpha$-aminoadipic acid.

To evaluate the effective use of endoprotease from squid viscera as a food processing aid, various methods of fractionating endoprotease from viscera of the Argentina shortfin squid (Illex argentinus) were evaluated. The endoprotease-positive fractions of each fractionation were fraction II (30-40%, w/w) with cold acetone, fraction IV (50-60% saturation) with ammonium sulfate, fraction UF with anion exchange chromatography, and fraction II (15-24 kDa) with gel filtration. The specific activities (approximately 25 U/mg) of the fractions using ammonium sulfate and gel filtration were higher than the others. Total azocaseinolytic activity and recovery of the positive fraction using gel filtration were 806.95U and 37.82%, respectively, and were the highest among the positive fractions. Based on the results, gel filtration was the most efficient method for fractionating endoprotease from the viscera of Illex argentinus.
