  • This experiment was conducted to study the effects of blood-mixed and heat-treated protein feeds on protein degradation in the rumen, flow of protein to the abomasums and availability of undegraded protein in the intestine of sheep in a $4{\times}4$ Latin square design. Soybean oil meal, rapeseed meal, and whole soybean were mixed with fresh swine blood and dried at $140^{\circ}C$ for 2 h. Proportionate disappearance of apparently digested OM in the postrumen for the blood and heat treated protein group was ranged from 43.2 to 50.5% as compared with 28.0% for the unheated soybean oil meal diet. The treated protein supplements were resulted in greater total N and NAN flow passing at the abomasums than untreated soybean oil meal diet was fed. The quantities of undegraded feed N passing at the abomasums for the treated protein diets was approximately twice as high as that of the untreated soybean oil meal diet and the estimated amount of undegraded N of the protein supplement itself was 79.1 to 84.2% as compared with 15% of soybean oil meal.

  • In terms of Yin and Yang theory, Dam represents excessive Yang and deficient Yin, and Bangkwang means excessive Yin and deficient Yang. In terms of Ki and Hyung, Dam is vigorous Ki and flabby Hyung, and Bangwang is strong Hyung and weak Ki. In terms of the balance of Ki and Blood, Dam is more Ki and less Blood and Bangkwang is the opposite. In terms of meridians concerned, Dam belongs to Joksoyangdam meridian(足少陽膽經) and Bangkwang belongs to Joktayangbangwang meridian(足太膀胱經), Mr. Jeesan saw that the person having vigorous Ki and flabby Hyung tends to be dynamic and the person having strong Hyung and weak Ki tends to be static and designated both as Dam and Bangkwang, respectively, Meridians are the route of Ki and Blood in the body and since their titles are thought to imply basic oriental medical theories, they are better choices to be comprehensive and systematic than other terms. In the 12 meridians, the 6 foot meridians are more important than the other hand meridians because human beings adapt themselves to the earth. Among the 6 foot meridians, the 3 Yang foot meridians are more representative of the body since they cover more of the body. Joksoyangdam meridian(足少陽膽經) is related to more Ki and less Blood and thus is a relevant term to describe Dam. Likewise Joktaeyangbangkwang meridian(足太膀胱經) is related to more Blood and less Ki and thus can correspond to the term 'Bangkwang'. In addition, the Dam organ and Dam meridians meet the condition of excessive Yang and deficient Yin, vigorous Ki and flabby Hyung, more Ki and less Blood, on the other hand, the BangKwang organ and Bangkwang meridians meet the condition of excessive Yin and deficient Yang, strong Hyung and weak Ki, more Blood and less Ki. Thus the terms of Dam and Bangkwang satisfy the basic concepts Mr. Jeesan established.

  • Nitrate-nitrite-nitric oxide (NO) pathway is a major alternative source of NO and is essential for NO - dependent physiological functions in body. Food supplements having nitrate/nitrite can improve metabolic syndromes including hypertension through antioxidant activity or vasodilation. The purpose of this study was to observe the effects of fermented garlic (F. garlic) having high concentration of NO2- on changes in blood flow and nitric oxide synthesis in the cerebral cortex of rodents. The generation of nitric oxide detected by a chemi-luminescence detector was higher in F. Garlic compared with NaNO2 solution under artificial gastric juice with pH 2.0. Ether F. garlic or NaNO2 diluted with artificial cerebrospinal fluid was directly applied into around the needle probe of laser Doppler flow meter that was located on epidural surface of the cortex. Direct application of F. garlic resulted in increase of cerebral blood flow detected by a laser Doppler flow meter with a dose-dependent manner. Compared with NaNO2 solution, F. garlic produced changes in cerebral blood flow at lower concentration of NO2-. Pretreatment of methylene blue, a guanylyl cyclase inhibitor prevented upregulation of cerebral blood flow by the treatment of F. garlic. In addition, the application of F. garlic with 250, 500ppm of NO2- caused significantly the production of NO in the cortical tissue but NaNO2 solution with 500ppm of NO2- did not. In summary, these results suggested that F. garlic with high content of NO2- induce increase in cerebral blood flow through nitric oxide-dependent signal pathway.

  • In the present study, an effort was directed to elucidate the effect of osmolality on the absorption of ethanol in rabbits. A single dose of 13.67 ml(2. 16 gm ethanol/kg BW) of hypo-, iso-hyphen and hypertonic ethanol per kg BW was administered into the stomach to albino rabbits and the experiment was performed at 30 th, 60 th and 120 th minute. The blood ethanol level was determined by the method of Williams et al, and hematocrit(Hct) was determined by the conventional Hct centrifuge and reader. The results are summarized as follow. The blood ethanol level showed the highest value at 60 min after the ethanol ingestion in the hypo- and isotonic groups, $171.3{\pm}13.3\;mg%$ and $204.5{\pm}23.0\;mg%$, respectively, but in the hypertonic group, the highest value was observed at 120min after the ingestion. The absorption rate of ethanol between 0 to 30 min after the ingestion of hypo- and isotonic ethanol was $88.54{\pm}12.04$ and $94.73{\pm}8.33\;mg/min$, respectively, but a decreased value of $44.72{\pm}6.69\;mg/min$ was noted after hypertonic ethanol ingestion comparing with hypo- and isotonic groups, The Hct value after hypo- and isotonic ethanol ingestion was decreased at 30 min but returned to the control level at 120 min. In contrast with hypo- and isotonic ethanol ingestion, hypertonic ethanol ingestion produced an increase of the Hct value at 30 min and returned to the control level at 120 min. The heart rate was increased but the respiratory rate was decreased after ethanol ingestion regardless of the osmolality.

  • The Kv channel activity in vascular smooth muscle cell plays an important role in the regulation of membrane potential and blood vessel tone. It was postulated that increased blood vessel tone in hypertension was associated with alteration of Kv channel and membrane potential. Therefore, using whole cell mode of patch-clamp technique, the membrane potential and the 4-AP-sensitive Kv current in cerebral arterial smooth muscle cells were compared between normotensive rat and one-kidney, one-clip Goldblatt hypertensive rat (lK,lC-GBH rat). Cell capacitance of hypertensive rat was similar to that of normotensive rat. Cell capacitance of normotensive rat and 1K,lC-GBH rat were $20.8{\pm}2.3$ and $19.5{\pm}1.4$ pF, respectively. The resting membrane potentials measured in current clamp mode from normotensive rat and 1K,lC-GBH rat were $-45.9{\pm}1.7$ and $-38.5{\pm}1.6$ mV, respectively. 4-AP (5 mM) caused the resting membrane potential hypopolarize but charybdotoxin $(0.1\;{\mu}M)$ did not cause any change of membrane potential. Component of 4-AP-sensitive Kv current was smaller in 1K,lC-GBH rat than in normotensive rat. The voltage dependence of steady-state activation and inactivation of Kv channel determined by using double-pulse protocol showed no significant difference. These results suggest that 4-AP-sensitive Kv channels playa major role in the regulation of membrane potential in cerebral arterial smooth muscle cells and alterations of 4-AP-sensitive Kv channels would contribute to hypopolarization of membrane potential in 1K,lC-GBH rat.

  • In an effort to elucidate the physiological characteristics in cardiopulmonary function, electromyogram(EMG), and blood chemistry in athletic high school students, an analysis of electrocardiogram(ECG) and EMG, pulmonary function test, venous blood gas analysis($Pvo_2$ and$Pvco_2$), and measurement of heart rate, blood pressure, respiratory rate, blood glucose and blood lactate were made for 16 to 19 year-old high school students who were divided into athletic (n=19) and non-athletic (n=20) group. The results obtained are summarized as follows. 1) ECG intervals in athletes were longer than in non-athletes, and the difference was significant in R-R, Q-T and T-P intervals. Resting heart rate in athletes was 56.3/min showing a bradycardia compared with 79.8/min in non-athletes. Amplitudes of R and T waves in lead $V_5$ were significantly higher than in non-athletes. 2) Pulmonary function parameters in athletes showed higher values than in non-athletes. Parameters which showed significant differences were FEV 0.5, PEF, FEF 25%, PIF and FEF $200{\sim}1.200\;ml. 3) Heart rate, blood pressure, and respiratory rate after exercise were significantly elevated from resting values. Heart rate and respiratory rate showed greater increase in non-athletes, while blood pressure showed greater increase in athletes. 4) $Pvo_2$ was lowered ana $Pvco_2$ was elevated after exercise, and there was no significant difference between two groups. 5) Blood glucose and lactate levels were elevated after exercise. The difference was significant in blood lactate, and was greater in non-athletes. 6) EMG amplitude was steadily increased with increasing load of exercise, and the increase was greater in athletes than in non-athletes.

  • Leukemia is a blood disease that occurs in the abnormal process of leukocyte maturation. Its main medical treatment is chemical therapy and bone medical transplant. But its treatments give rise to ill effects and sequela. At present, the cause of leukemia is not fully understood. But oriental concept of curing leukemia is the holistic thinking that emphasizes the unity, wholeness, and the relationship between the human organs, including western medical concept of blood cause. So it is estimated that holistic medical treatment in oriental medicine could present new medical way of curing leukemia. I read over the diary on struggles against leukemia, survey on the leukemia patients, and, medical charts in the oriental clinics that treated in the holistic way, and I interviewed the leukemia patients. With these materials, I classified the early main attacking symptoms according to the chief complaints of one hundred leukemia patients. With these results collected, I present new alternative treatment by oriental medical diagnosis. The chief early complaints that leukemia patients give are fatigue, enervation, cold, contusion, fever, high fever, sweating at sleep, myalgia, arthralgia, and dizziness, in order of main symptoms. Fatigue occurs mainly by spleen and stomach weakness and marrow shortage. So it is estimated that It is important to treat the spleen that is responsible for supplementing the marrow. Because the leukemia patients have anemia and hemorrhage, to treat the spleen is important for hematopoiesis and controlling blood. In case of cold, it penetrates into the body when the body is weak. So its treatment is to increase body's health. But the cause of fever is difficult to classify into outer cause and inner cause. But in case of children under 14 years old, fever is the main sypmptom. I think this is because children have the body with pure vital energy. Hemorrhage is thought to be the result of yin-lack and heat-miasma of spleen and stomach channels. Contusion occurs from the qi-weakness and the not-controlling-blood. Sweating at sleep is from the yin-weakness. It is found with all weak symptoms. Dizziness is from the yin-blood impairment. Weight-loss is from the marrow shortage. Myalgia and arthralgia is mainly from inner weakness, not outer maisma. Most leukemia patients have the idea that holistic treatment of leukemia could be of assistance and give help to the low immunity. So it is expected that holistic medical treatment could contribute to knowing the cause and treatment of leukemia, and give people reliability on oriental medical treatment, through the profound diagnosis of leukemia.

  • This clinical experience reports the effect of wood and fire acupoints therapy on a hypertensive patient. Wood acupoint indicates Jing point in yin channel or Shu point in yang channel. Fire acupoint is Jing in yin channel or Jing in yang channel among the five acupoints of Jing, Xing, Shu, Jing and He. The patient was treated with indicated acupoints of 7 channels: lung, large intestine, spleen, pericardium, triple warmer, heart and liver, for 5 weeks. In case of necessity, another acupoints were added with wood and fire acupoints. After 5 weeks treatment, the blood pressure improved by 125/80 which is in normal level. This result suggests that wood and fire acupoints therapy is effective in the treatment of hypertension.

  • Four castrated Corriedale sheep were used in an experiment to observe the changes in insulin, growth hormone and cortisol in blood plasma following a prolonged infusion of a high rate of somatostatin (SRIF). The animals wee infused with either saline, 25 or $50{\mu}g/kg/h$ of SRIF for 3 hours. Blood samples wee taken every 20 minutes until 1 hour following the end of the SRIF infusion. Both SRIF infusion levels suppressed the release of insulin into plasma to approximately 3.5 mU/l. The SRIF infusions reduced the concentration of growth hormone to barely detectable levels. Following the withdrawal of SRIF there was a massive release of growth hormone. The plasma concentration of growth hormone reached 60 ng/ml within 20 minutes, the length of the growth hormone discharge was in excess of 1 hour. The extent of the discharge of growth hormone following the SRIF infusions was greater than that suppressed by the infusion. The SRIF apparently caused an increase in the plasma concentration of cortisol at the end of the infusion and following is withdrawal. This is possibly associated with some change in the metabolic rate associated with the suppression of insulin or glucagons release. The present experiment demonstrates that a high rate of SRIF infusion can not completely inhibit the release of insulin into the plasma.
