  • PURPOSE: Low-intensity exercise with transient restriction of blood flow to muscle could be an alternative rehabilitation method which avoids the problems associated with conventional high-intensity exercise. However, the mechanism of low-intensity exercise with transient restriction of blood flow is not clearly known. Thus, the purpose of this study was to investigate the mechanism of improvement of muscular function after low-intensity exercise with transient restriction of blood flow using H-reflex analysis. METHODS: Twenty one healthy young adults with no medical history of neurological or musculoskeletal disorder voluntarily participated in this study. The ${\alpha}$-motor neuron excitability of the triceps surae was assessed using the H-reflex. The amplitude of the M-wave and H-reflex were measured across three conditions: rest, after low-intensity exercise without restriction of blood flow and after low-intensity exercise with restriction of blood flow. The subjects performed low-intensity ankle plantar flexion exercise at their own pace for one minute without or with transient restriction of blood flow achieved by a sphygmomanometer cuff on popliteal fossa at a pressure of 120mm of mercury(120 mmHg). RESULTS: No significant changes of the excitability of the ${\alpha}$-motor neuron were obtained across three different conditions. CONCLUSION: This study found that low-intensity exercise with transient restriction of blood flow did not influence to ${\alpha}$-motor neuron excitability of the triceps surae. From the results, I could come to the conclusion that further study will be required.

  • This study analyzed the physical indices, food habits and nutrient intakes of patients with hypertension, to provide better research data for the prevention and the cure for disease as well as basic data for nutrition education. The subjects were 44 patients who visited the general hospital, located in Daegu, to receive hypertension treatment The lifestyle, food habit, nutrient intakes, anthropometric measurements, body fat and blood pressure were measured as main indices. By the BMI, $72.8\%$ of the patients were over weight or obesity $(>23\;kg/m^2)$. In the male group, the WHR tended to increase according to the BMI (p<0.05). In the female group, the body fat tended to increase according to the BMI (p<0.05). The group with more monthly income showed lower systolic blood pressure than the group with smaller monthly income (p<0.05). The scores about food habits concerning balanced diet and preference for salt were low, which implied that food habits of subjects were not desirable. The intakes of riboflavin and calcium didn't meet the RDA requirements. Especially, the lack of calcium was more ap~nt in the female patients than the male ones. Despite this, they had more than enough protein, vitamin C, and iron. The physical indices according to blood pressure revealed that the group of higher blood pressure showed greater WHR (p<0.001). The male group with higher systolic blood pressure showed greater BMI than one with lower systolic blood pressure (p<0.05). As for nutrient intakes according to blood pressure, the group with higher blood pressure had more sodium and iron than one with lower blood pressure (p<0.05). The patients with hypertension tended to be more overweight or obese, preferred salty foods, and were in an unbalanced state of nutrient intakes. Thus more systematic and ongoing measures should be pursued to take care of patients with hypertension.

  • We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.

  • Background: The purpose of this study is to investigate the change of blood pressure and autonomic neural system through one-time bamboo stepping in hypertensive elderly people. Design: Randomized Controlled Trial. Methods: We recruited 26 elderly people aged 65 or older for study. They sat for 10 minutes in a chair, rested, and measured pre-exercise blood pressure and autonomic neural system. The blood pressure was measured three times and the mean value was used and the autonomic neural system was measured once. Bamboo stepping exercise was performed for 20 minutes. Blood pressure and autonomic neural system were measured 5 times immediately after exercise, and every 15 minutes at 60 minutes after bamboo stepping exercise. Results: There was a significant difference in the decrease of systolic blood pressure after one-time bamboo stepping exercise, the change of parasympathetic activity (HF), heart rate variability (HRV) and BPM measured immediately after exercise at 15 minutes after exercise, There was no significant difference in autonomic neural system change. Conclusion: One-time Bamboo stepping exercise is effective in decreasing systolic blood pressure of the hypertensive elderly.

  • Purpose: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. Methods: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, ${\leq}2,300g$ or were ${\leq}36$ weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). Results: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels ${\leq}60mg/dL$, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment, after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose ${\leq}60mg/dL$), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. Conclusion: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.

  • To investigate the mechanisms of increased endothelium-dependent contraction by acetylcholine in hypertensive rats, the relationship between endothelium-dependent contraction by acetylcholine and blood pressure was studied in spontaneously hypertensive rats (SHR), one-kidney, one clip Goldblatt hypertension (1K,1C-GBH) rats, and Wistar-Kyoto rats (WKY). SHR were treated orally with enalapril or nicardipine in order to prevent development of hypertension or suppress the developed hypertension. 1K,1C-GBH rats were made by renal artery stenosis with contralateral nephrectomy in 8 week-WKY. 1. Endothelium-dependent contractions by acetylcholine $(10^{-6}{\sim}10^{-5}\;M)$ in SHR were significantly greater than those in WKY. 2. Chronic treatment with enalapril or nicardipine reduced the endothelium-dependent contraction in SHR 3. The degree of reduction of endothelium-dependent contraction was greater in SHR which was prevented from developing hypertension than in SHR of which high blood pressure was suppressed. 4. In aortic rings from 1K,1C-GBH rats, endothelium-dependent contractions by acetylcholine were augmented as compared with WKY. 5. There is good relationship between the value of blood pressure and magnitude of endothelium-dependent contraction. Thus, it is suggested that increased endothelium-dependent contraction in hypertensive rats may he due to the high blood pressure and endothelium-dependent contraction may not be a cause of the initiation of hypertension in SHR.

  • A reduced NaCl intake for the general population of the world has been recommended to reduce the overall blood pressure level and hence to reduce the overall incidence of cardiovascular disease. A high NaCl diet convincingly contributes to elevated arterial pressure in humans and animal models of hypertension. Among individuals there is considerable variability of blood pressure responsiveness to NaCl intake. In normotensive as well as hypertensive subjects, blood pressure can be judged to be salt sensitivity (SS) when observed to vary directly and substantially with the net intake of NaCl. The prevalence of SS in normotensive adults in the U.S. ranges from 15% to 42% and in hypertensive adults from 28% to 74%. SS is a risk factor for hypertension and may be an important marker in the identification of children for hypertension prevention programs. High NaCl intakes produce expansion of the extracellular fluid volume and thus increase blood pressure. Nonchloride salts of sodium does not expand the extracellular fluid volume and does not alter blood pressure. Blood pressure response to NaCl may be modified by other components of the diet. Low dietary intakes of potassium or calcium augment NaCl-induced increases of blood pressure. Conversely, high dietary intakes of potassium or calcium attenuate NaCl-induced hypertension. A greater intakes of potassium or calcium may prevent or delay the occurrence of hypertension. SS occurs when dietary potassium is even marginally deficient but is dose-dependently suppressed when dietary potassium is increased within its normal range. Orally administered KHCO$_3$, abundant in fruits and vegetates, but not KCl has a calcium-retaining effect which may contributed to its reversal of pressor effect of dietary NaCl. Since nutrients other than NaCl also affect blood pressure levels, a reduced NaCl intake should be only one component of a nutritional strategy to lower blood pressure.

  • 이 연구는 중 고등학생들의 혈액형과 뇌 기능 및 좌우뇌선호도와 관계가 있는지를 개인이 지닌 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 비교 하여 보았다. 대상자는 2005년 9월에서 2008년12월까지 한국정신과학연구소에 뇌파측정 의뢰한 중 고등학생을 기준으로 선정한 자료이다. 중학생 여 628, 남 1002, 고등학생 여 213, 남 365, 총 2208명이다. 중 고등학생 혈액형 분포도는 A>B>O>AB형 순이었다. 분석의 결과 중 고등학생의 혈액형과 좌우뇌선호도와는 무관하였다. 그리고 혈액형과 중 고등학생의 뇌 기능과도 무관하였다. 위의 결과를 종합하면 혈액형과 지능이나 성격을 함부로 연관지어 편견이나 차별을 유도 하는 것은 바람직하지 않다고 본다.

  • Purpose: In oriental medicine, doctors have mainly made diagnosis and treatment with amenorrhea or delayed menstrual period based on overall analysis of symptoms and signs patients have. We think patients with amenorrhea or delayed menstrual period to have symptoms that are classified into one differentiation of syndromes, and then studied to make the index. This study has been carried out to investigate pattern identifications and classify symptoms according to them. Methods: We examined 52 patients who visited Dong-eui university oriental medical center from June 2005 to February 2009 for undergoing treatment for amenorrhea or delayed menstrual period and made OB & GY questionnaires up Results: We investigated whether the patients had symptoms concerned with symptom types by analyzing the result of DSOM(Diagnos System of Oriental Medicine, hearafter DSOM). It came out 51 cases among 52 with pathogenesis that was related to the symptom types. The symptom types of were surveyed into Insufficiency of Kidney and Liver(肝腎不足), Insufficiency of Qi and Blood(氣血虛弱), Insufficiency of Yin & Dryness of blood(陰虛血燥), stagnation of Qi and Blood(氣滯血瘀), phlegm and damp(痰濕阻滯), coldness of Blood(血寒), Heat of Heart(心火). Conclusion: As a result of the investigation, one case did not have symptoms of differentiation of syndromes of amenorrhea or delayed menstrual period. 29 cases had 1 or 2 differentiation of syndromes. 21 patients had such complex symptoms of diverse differentiation of syndromes that it was difficult to diagnose a differentiation of syndromes in clinical survey. It is necessary to put the priority among the differentiation of syndromes in diagnosis in the future.
