Insomnia is defined as an experience of inadequate or poor-quality sleeping habit, coupled with more than one of the following symptoms : having difficulty sleeping, waking up too early in the morning or not having sound sleep. Insomnia is one of the most common complications that stroke patients experience, which interfere the patients' recovery. The authors observed two improved cases of insomnia in stroke patients by administrating traditional Korean medicine. The patients suffered from insomnia with nocturnal irritation, constipation, petechia of the tongue, thready or weak pulse. These symptoms, were diagnosed as blood stasis and we administered Hyulboochucke-tang three times a day, to improve blood circulation to remove blood stasis. After the administration, nocturnal irritation disappeared and the insomnia improved. Based on this experience, it is considered that enhancing blood circulation to remove blood stasis can be applied to the treatment of insomnia that stroke patients suffer.

Objectives : The purpose of this paper is to study the origin, mechanism, category of Chest bind with static blood(血結胸), the relation to the syndrome of Heat entering the blood chamber(熱入血室證), and the comparison with Chest bind(結胸). Methods : Sikuquanshu(四庫全書), a comprehensive range of medical books, and Shanghanlun(傷寒論) annotation books were searched by 'Chest bind with static blood' keyword and analyzed. Results & Conclusions : 1. The syndrome of Chest bind with static blood is first brought up by ZhuGong(朱肱) and it can be derived from the syndrome of Heat entering the blood chamber or can be shown in upper middle lower energizer Stagnated Blood Syndrome(上中下焦蓄血證, SBC). Ever since the publication of Shanghanquanshengji(傷寒全生集), its category was expanded and prescriptions for the SBC were used. 2. In comparison, the cause of Chest bind with static blood is associated with blood heat(血熱), largely connected with blood, mental illness appeared, lesions are usually chest and sides, and the cause of Chest bind is associated with intermingled water heat (水熱) or phlegm heat(痰熱), not connected with blood, mental illness not appeared, lesions are from the beneath the heart to lower abdomen. 3. The syndrome of Chest bind with static blood derived from the syndrome of Heat entering the blood chamber can appear along side with the Liver Meridian associated with blood chamber or appear in chest, the syndrome appeared in upper energizer SBC can be shown in the chest due to gravity, the one appeared in middle energizer SBC can be shown in the chest due to the same level, the one appeared in lower energizer SBC can be shown in the chest due to the constitutional predisposition of YangQi(陽氣) uprise.

Studies were undertaken on the changes in the renal blood flow by relating them with the alterations in the amplitudes in the rheogram of rabbits. The changing pattern of the electrical conductivity was recorded by means of the needle electrodes inserted into the kidney and the surrounding aluminium foil which was grounded. The Impedance Rheograph manufactured by the Narco Company was used. The small artifact which persisted after ligation of the renal vessels was subtracted from the value obtained in each pulsatile wave in the rheogram. The animals were nembutalized intravenously, 30 mg/kg. A plastic canule was inserted into the carotid artery and the arterial blood pressure was monitored continuously with the pressure transducer connected to the physiograph. Stepwise bleedings were performed on the animal. The first bleeding was between 13 to 18 ml in the amount, and it was folowed by consecutive hemorrhages, 5 or 10 ml each time. The total amount of bleeding was summed as much as 1.5-2% of the body weight. Two minutes fter each bleeding th arterial blood pressure, ECG and the rheogram were taken. That was the necessary time to obtain the stabilized picture of each parameter. After closing the bleeding process, the shed blood was retransfused into the animal and the response in the renal blood flow was observed as well as the arterial blood pressure. Particularly the presence or absence of the autoregulatory mechanism in the situation of the hemorrhage was also studied. The results obtained were as follows: 1. In 7 cases out of 22, that was about one third of the total number of experiments, the autoregulatory mechanism of the renal blood flow persisted even in acute hemorrhage, and the decreases in the renal blood flow were less than 10% of the control values even when the arterial blood pressure dropped to 66-87% of the original value obtained before the bleeding. 2. Because of the stepwise bleeding the exact blood pressure at which the renal blood flow reduced as much as one third of the control value could not be obtained. However, the results revealed that the approximate pressure, expressed as percentage of the control value, was 50-60% in 3 cases, 61-70% in 4 cases and 71-80% in 8 cases. In one case the decrease in the renal blood flow exceeded one third of the control value before the pressure dropped to 80% of the control. 3. In 19 cases the decreases in the renal blood flow exceeded one half of the control values by hemorrhage. Then the arterial blood pressure revealed less than 40% of the control value in 6-cases. In 2 cases the pressure was 51-60% of the control pressure. In 5 cases the range of bleed pressure was 61-70%, and in e remaining 6 cases the pressure ranged from 71 to 80% of e control value. 4. Out of 15 cases of retransfusion after definite decreases in the renal blood flow loller·ing the hemorrhage, 9 cases restored their renal blood flow. On the contrary 6 cases showed low values even when the shed blood was retransfused. 5. Theories concerning the mechanism of the autoregulation of the renal blood flow were reviewed for the purpose of explanation of the results obtained. However, there are much to be done before greater satisfaction

The PLA2G4A catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid, which is metabolized into lipid-based cellular hormones that regulate inflammatory response. The circulating blood cell numbers can be influenced by stress, infection or inflammation. Quantitative blood cell count traits analysis for the 19 SNPs in the PLA2G4A gene in the Korean Association Resource (KARE) cohort (7551 subjects) was performed. The only one SNP (rs10752979) in the all blood cell count was satisfied with the Bonferroni corrected P-value (<0.00263). Furthermore, 6 of the 19 SNPs in the PLA2G4A gene showed a weak or moderate association with blood cell count (P-values: 0.0048~0.042), suggesting the clue of an association between the PLA2G4A gene and blood cell count, especially white blood cell count. This study may provide insight into the genetic basis of blood cell count related with reaction of infection.

Appreciation of the large volume deficits which may occur in surgical or trauma patients due to blood loss has led to vigorous transfusion techniques designed to overt hypovolemic shock and ischemic damage to vital organs which may develop in minutes during the hypovolemic state. In a significant proportion of patients treated with massive rapid blood or fluid transfusion, hypervolemia occurs and life threatening pulmonary edema may develop. Especially, hypervolemia may occur during transfusion for preventing development of the so-called low output syndrome following cardiac surgery. However, the most effective indicator which reveals the adequate level of transfusion is not settled yet. The present study was aimed to compare the effectiveness of the indicators suggested thus far and to determine the most sensitive one. Eight dogs were experimentally studied in terms of left atrial pressure, pulmonary arterial systolic pressure, central venous pressure, mean systemic arterial pressure and heart rate before and after induced hypervolemia with infusion of 600ml heparinized homologous blood. Immediately after induced overtransfusion of the blood, pulmonary arterial systolic pressure increased 75.0%, in omparison with the control before transfusion, left atrial pressure 58.8%, central venous pressure 44.6%, and mean systemic arterial pressure 10.1%, one hour after transfusion, pulmonary arterial systolic pressure 40.0%, left atrial pressure 21.2%, central venous pressure 14.5%, and mean systemic arterial pressure 3.2%, central venous pressure 14.5%, and mean systemic arterial pressure 3.2%, respectively. Heart rate showed no significant change throughout the experiment. These result suggested that the changes of the pulmonary arterial systolic pressure is the most sensitive indicator for detection of hypervolemia during blood transfusion.

Several studies revealed that low calcium intake is related to high prevalence of cardiovascular diseases such as hypertension. The prevalence of hypertension is high in Koreans along with their low dietary calcium consumption. Thus, the aim of this study was to evaluate the status of calcium intake between the hypertension and normotension groups and to investigate the correlation between dietary calcium intake and blood pressure, blood lipid parameters, and blood/urine oxidative stress indices. A total of 166 adult subjects participated in this study and were assigned to one of two study groups: a hypertension group (n = 83) who had 140 mmHg or higher in systolic blood pressure (SBP) or 90 mmHg or higher in diastolic blood pressure (DBP), and an age- and sex-matched normotension group (n = 83, 120 mmHg or less SBP and 80 mmHg or less DBP). The hypertension group consumed 360.5 mg calcium per day, which was lower than that of the normotension group (429.9 mg) but not showing significant difference. In the hypertension group, DBP had a significant negative correlation with plant calcium (P < 0.01) after adjusting for age, gender, body mass index (BMI), and energy intake. In the normotension group, total calcium and animal calcium intake were significantly and positively correlated with serum triglycerides. No significant relationship was found between calcium intake and blood/urine oxidative stress indices in both groups. Overall, these data suggest reconsideration of food sources for calcium consumption in management of the blood pressure or blood lipid profiles in both hypertensive and normotensive subjects.

Hemorheology plays an important role in atherosclerosis. Hemorheologic properties of blood include whole blood viscosity, plasma viscosity, hemaocrit, RBC deformability and aggregation, and fibrinogen concentration in plasma. Blood flow is determine by three parameters (pressure, lumen diameter, and whole blood viscosity), whole blood viscosity is one of the key physiological variables. However, the significance of whole blood viscosity has not yet not been fully appreciated. Whole blood viscosity has a unique property, non-Newtonian shear-thinning characteristics, which is primarily due to the presence of RBCs. Hence, RBC deformability and aggregation directly affect the magnitude of blood viscosity, and any factors or diseases affecting RBC characteristics influence blood viscosity. Therefore, on can see that whole blood viscosity is the causal mechanism by which traditional risk factors such as hypertension, hyperlipidemia, smoking, exercise, obesity, age, and gender are related to atherogenesis. In this regard, we included whole blood viscosity in the three key determinants of injurious pulsatile flow that results in mechanical injury and protective adaptation in the arterial system. Because whole blood viscosity is a potential predictor of cardiovascular diseases, it should be measured in routine cardiovascular profiles. Incorporating whole blood viscosity measurements into a standard clinical protocol could improve our ability to identify patients at risk for cardiovascular disease and its complications.

Hypertension is a complex disease that results from the interaction of genetic and environmental influences and heritability is influenced by about one-third to one-half. However, the specific genetic variants determining risk for hypertension are still largely unknown. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in ESR1 gene with blood pressure traits. By examining genotype data of a total of 3,804 women in the Korean Association REsource (KARE) study, we discovered the ESR1 gene polymorphisms are associated with blood pressure and hypertension. The highest significant polymorphisms were rs2982571 (${\beta}=-1.56$, $P=6.8{\times}10^{-3}$) with systolic blood pressure (SBP), rs9322335 (${\beta}=-0.61$, P=0.013) with diastolic blood pressure (DBP), and rs851985 (OR=0.78, CI: 0.65~0.94, $P=8.6{\times}10^{-3}$) with hypertension. In the 5 SNPs (rs2982571, rs851985, rs851983, rs851981, and rs851980), their ${\beta}$-values in SBP and/or DBP showed consistent trends with the odds ratios (ORs) of hypertension, and these 5 SNPs were composed with one LD block. Consequently, we found statistically significant SNPs in ESR1 gene that are associated with both blood pressure and hypertension traits. These results suggested that the individuals with the minor alleles of the 5 SNPs in the ESR1 gene may be less susceptible to the development of hypertension in the Korean women.

To evaluate the effectiveness of cupping and bloodletting therapy in the treatment of musculoskeletal diseases. Systematic searches were conducted on KSI, KISTI, DB Pia, KIOM Database, and Koreamed until January 2007 Hand-searches included conference proceedings and our own files. There were no restrictions regarding the language of journals published in Korea. Controlled trials of dry cupping, wet cupping, or blood letting for patients with musculoskeletal disease were considered for inclusion. Trials testing other forms of dry cupping therapy were included. Methodological quality was assessed by two doctors. 20 possibly relevant studies were identified and 5 studies were included. One trial tested wet cupping for ankle sprain and reported positive result. Two trials tested blood letting for low back pain, one was positive and the other one was neutral. One trial tested the types of dry cupping for low back pain, and Ki-gong cupping therapy was superior to other two types of cupping. One trial compared wet cupping with dry cupping for low back pain and the result was negative. The effectiveness of bloodletting plus acupuncture for treating patients with low back pain is superior to acupuncture in spite of low quality. One trial of wet cupping for ankle sprain had effects in reducing pain. However, I suggest that the rigorous RCTs of cupping and blood letting therapy will be conducted in well designed features.

Herpes simplex encephalitis (HSE) is one of the fulminant necrotizing, often fatal sporadic form of the encephalitis caused by herpes simplex type I virus. Characteristically, there is early and almost constant involvement of one or both temporal lobes, although there are common additional areas of involvement. Appropriate early treatment following correct diagnosis by clinical findings, CSF study, EEG and several radiological studies including angiography, redionuclide studies, CT or MRI can reduce its mortality and severity of the sequelae. We report a case of HSE diagnosed by adjuvant study of $^{99m}Tc-HMPAO$ regional cerebral blood flow SPECT, which showed a marked increase in bitemporal cerebral blood flow in a 24-year-old man.
