The total proteins were estimated in both deoxycholate (DOC)-extract of sperm membrane and seminal plasma of chilled as well as frozen semen obtained from five Murrah buffalo bulls. Proteins were further characterized by polyacrylamide gel electrophoresis (PAGE) in three bulls. The protein content of sperm membrane extract (SME) and that of seminal plasma (SP) decreased gradually with increase in freezing period from 6 to 24 mo when compared with the values observed in freshly chilled semen in all bulls. The total decrease in protein content of SME and SP varied from 30-40% and 28-59% respectively during 6-24 mo of freezing. The number of glycoproteins/proteins (GP/P) in SME varied from 4-8 in freshly-chilled semen of all bulls and reduced to 2-4 after 24 mo of freezing. In SP, the number of proteins varied from 6-10 in freshly chilled semen of all bulls and reduced to 3-8 after 24 mo of freezing. Some of the proteins in SME and SP disappeared, others got altered and appeared with change in molecular weight after different freezing times. These studies reveal that alterations in the sperm membrane proteins may be responsible for damage to their membrane during freezing and thus lowering their fertilizability.

Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

Chicory is used popularly. We use leaves of the plant as ordinary mea1, and roots as a substitute of tea materials. It also has been asserted that it has clinical effects on weakness, hepatic disease, diabetes, etc. However, experimental evidences are so insufficient that we started these studies. For antiinflammatory activity, MeOH Ex. was orally administered to rats, and decreased amounts of paw edema induced by carrageenan injection were measured. For bile secretion increament, rats were administered total MeOH, EtOAc fraction, and BuOH fraction Ex. respectively. One hour later, bile ducts were cannulated, and we collected bile every 20 minutes for 4 hours. For hepatoprotective activity, CCl$_4$-intoxicated mouse were treated with MeOH Ex., then s-GPT, S-GOT, and liver weight were measured. For antidiabetic activity, rats were induced diabetes by streptozocin 45mg/kg(i.v) injection. One week later, 1000mg/kg of total MeOH Ex. of chicory root was orally administered. We divided rats into three groups. Group 1 rats were administered only once, group 2 ones once a day for one week, and group 3 ones for three weeks. The concentrations of serum glucose were measured before and after administration. For antihypertensive activity, SHR were administrated total MeOH Ex. of chicory once a day for 8 days, and were measured blood pressure on 1st, 3rd, 6th and 8th day. Total MeOH, EtOAc fraction, and BuOH fraction Ex. increased bile secretion in rats, and decreased liver toxicity induced by CCl$_4$ in mouse. Total MeOH, Ex. of chicory roots has antiinflammatory effect, and decreased blood glucose concentration in group 2 and 3 rats. It was revealed not lowering blood pressure significantly in SHR.

본 논문에서는 카제인 가수분해물의 in vivo 상에서 혈압강하 효과를 알아보고, 혈압강하 기능을 갖는 기능성 펩타이드로서의 활용 가능성을 검토하기 위하여 안전성 검사를 실시하였다. 카제인 가수분해물의 소화관 단백질 분해효소 (펩신, 트립신, 카이모트립신) 내성 시험 결과 카제인 가수분해물은 소화관 효소 처리에 의하여 ACE 저해효과에 차이가 없었으며, 자연발증고혈압쥐를 이용한 혈압강하 실험에서 500 mg/kg을 경구 투여한 결과 12.9% (－28.88 mmHg, P<0.05) 저하하였고, 이들 가수분해물을 30% 난황으로 유화할 경우 15.9% (－30.76 mmHg, P<0.01)의 혈압이 감소하여 난황으로 유화에 의해 다소 혈압강화 효과가 증가하였다. 장기 투여에 의한 혈압강하 효과에서 35일 부터 수축기혈압 감소효과가 나타났으며 12.46% (P<0.05) 감소하였다. 가수분해물의 장기투여에 의한 자연발증고혈압쥐의 체중변화는 대조구와 비교하여 차이가 없었다. 혈압강하 효과를 가지는 카제인 가수분해물의 안전성을 조사한 결과 간장장애 지표로서 사용되는 GOT, GPT 활성에 차이가 없었다. 간장 비대 등의 장기 비대 현상도 없었고 조직병리학적 검사에서도 차이가 없었다. ACE 저해활성을 가지는 카제인 가수분해물은 혈압강하제와 비교하였을 때 비교적 낮은 활성을 나타내지만 항상 섭취하는 식품 중에 존재한다는 점에서 그 유용성이 기대되며, 고혈압 예방을 위한 기능성 식품이나 의약품으로서 개발하기 위해서 앞으로 ACE 저해 펩타이드에 대한 체계적인 안전성 검사가 이루어져야 할 것으로 생각된다.

This dissertation aims to study the five tastes in the Yellow Emperor's Canon of Internal Medicine. Medicinals as well as Foods are classified by the five tastes: sweet, sour, bitter, salty and pungent, which can be tasted by the tongue. With the development of the theory dealing with the medicinal properties, some flavors are summarized out of clinical actions of medicinals, therefore, there is a little difference between the flavors of medicinal herbs and the tastes got by tongue. Each taste acts on or has direct influence on a specific vital organ, and each of which has different physiologic actions. Taste also has a long-term or post digestive effect on the body and its metabolism. When each taste is consumed in moderation, it benefits the corresponding organ. Over-indulgence in any taste harms the organ and creates imbalance among the five vital organ systems. The Korean medicinal herbs with same flavor mostly possess similar actions while the medicinal herbs with different flavors show different actions in the treatment, which are shown as follows. Sour has absorbing, consolidating and astringent actions and acts on the liver. Bitter has the actions of drying or resolving dampness, purging and lowering and acts on the heart. Sweet has the nourishing, harmonizing and moistening actions and acts on the spleen. Pungent has an action of dispersing and promoting circulation of gi and blood and acts on the lungs. Salty has the effects of softening hard nodes or masses and promoting defecation, etc and acts on the kidneys. The five organ systems control and support each other. Proper coordination only exists when there is no one organ stronger or weaker than the rest. Since the five tastes have direct influences on the five organs, the diet we take should have a good combination of the five tastes in order to promote internal balance and harmony. They control our well-being and create dietary balance. Excessive consumption of any of these could result in adverse effects. In a word, when the properties of the five tastes respectively are distinguished, their natures and flavors cannot be separately considered. I think the harmonization of food and medicinals should be stressed on good nutritional diet to maintain good health. The traditional belief that food and medicine share the same origin is a part of Korean medicine tradition.
