  • The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in selfefficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

  • This study aimed to investigate whether nociceptin contributes to the alterations in cerebral blood flow (CBF) regulation following postnatal exposure to ethanol in Sprague-Dawley rats. Animals received ethanol twice a day, 2 hr apart, on postnatal 6, 7 and 8 days. The changes in regional CBF (rCBF) in response to the changes in mean arterial blood pressure were determined at 4-, 8-, and 12-week of age by laser-Doppler flowmetry. Hypotension was induced by the gradual withdrawal of blood from arterial catheter, and the reversal of blood pressure was produced by the reinfusion of blood. Expression of nociceptin-like immunoreactivity was determined in dura mater and cerebral cortex using immunohistochemistry. Postnatal exposure to ethanol almost abolished the autoregulation of rCBF in all age groups. Pretreatment with nociceptin but not with [$Nphe^1$]nociceptin(1-13)$NH_2$, a selective competitive nociceptin receptor antagonist, 5 min prior to ethanol administration preserved the autoregulation of rCBF in all age groups. Postnatal exposure to ethanol markedly increased the expressions of nociceptin-like immunoreactivity in the dura mater and cerebral cortex, both of which were significantly inhibited by pretreatment with 7-nitroindazole monosodium salt as well as aminoguanidine 5 min prior to ethanol administration in all age groups. The values of arterial blood gas analysis were not significantly different from the basal levels in all groups. These results suggest that nociceptin deeply contributes to the compensatory mechanisms for the nitric oxide-dependent alterations in CBF autoregulation following postnatal exposure to ethanol.

  • In February 1991 I initiated a blood conservation program that included hemodilution, use of a cell conservation device to concentrate diluted blood from operative field and from mediastinal shed blood, acceptance of a minimal hematocrit level of 25% in stable patients, and strict avoidance of use of blood products without definitive indication. A retrospective study to evaluate the effects of blood conservation program was designed to compare the amount of homologous transfusion, hematologic data, and postoperative outcome in patients operated on before and after initiation of blood conservation program. Patient characteristics were not different between two groups, before[n = 18] and after[n = 42] initiation of the program. The significant decrease of homologous transfusion[5.2 vs 1.4 units] and the marked increase of nontransfused patients[none vs 57%] in experimental group were due to marked decrease in homologous transfusion during the operation[4.6 vs 0.7 unit]. I conclude that with strict intraoperative blood conservation program, cardiac patients can be operated on with minimal homologous transfusion.

  • Background: This study aimed to analyze the on heart rate, blood lactate concentration, packed cell volume (PCV) and hemoglobin (Hb) response after conducting exercise in endurance horses. Methods: A total of 20 healthy 3-9-years-old Jeju crossbreed mares ($5.95{\pm}2.24$ year) of age and $312.65{\pm}13.59kg$ of weight) currently participating the endurance competition were used. The field tests selected for the experiment was gallop (approximately 8.3 m/s) along the selected 2.5 km course (a natural forest trail, not artificial road; a closed loop course). The horses were divided into three groups according to their age; 3-4 years of age (G1, $3.29{\pm}0.49$ year), 6-7 years of age (G2, $6.42{\pm}0.53$), and 8-9 years of age (G3, $8.50{\pm}0.55$). The measurements times for the heart rate, blood lactate concentration, PCV, and Hb analysis were conducted before exercise (T0), shortly after exercise (T1), 15 min after exercise (T2), and 30 min after exercise (T3), respectively. Data was analyzed using an analysis of covariance (ANCOVA) for repeated measures with times and groups. Results: The results of the comparison depending on the passage of rest time after exercise suggest that the heart rate and blood lactate concentration of three groups at T2 significantly decreased compared to T1 (p < 0.001). PCV of the G2 and G3 groups were significantly decreased at T2 compared to T1 (p < 0.01). Hb values at G2 (p < 0.01) and G3 (p < 0.001) groups were significantly decreased at T2 as compared to T1. However, heart rate, blood lactate concentration, PCV and Hb level at T1 showed no difference in the comparison of horses from different age groups with the exception of G3 group in terms of heart rate. Conclusion: The physiologic and hematological responses of horses during recovery time after 2,500 m exercise with gallop were no significant difference among the groups. These data are useful as a response evaluation method for training of endurance horses.

  • This study was designed to investigate a natural medicinal multi-plants extract (BG515), which consisted of multi extracts of Mori folium, Rehmannia glutinosa Liboschitz, Dioscorea japonica, Lycii fructus, and Astragalus radix, on blood glucose, insulin levels, and serum malondialdehyde (MDA) concentrations in streptozotocin-induced diabetic rats. Streptozotocin (STZ) induces a type 1 diabetes mellitus in rats. Type 1 is usually characterized by the presence of islet cell autoantibodies (ICA), autoantibodies to insulin (IAA), and autoantiboides to glutamic acid decarboxylase (GAD), which identify the autoimmune process that leads to $\beta-cell$ destruction. Thirty-five male Sprague-Dawley (SD) rats weighing $150\sim170g$ each (6 weeks old) were randomly divided into one control (Group A) and 4 STZ-induced diabetic groups, and were subjected to one of the following treatment for 12 weeks. Groups A and B were fed basal diets and Group C, D, and E received the same diets as groups A and B, but with supplements of 150 mg/kg, 300 mg/kg, and 600 mg/kg of BG515 orally for 12 weeks, respectively. Diabetes was induced in Groups B, C, D, and E by intravenous injection of 45 mg/kg of STZ per body weight in sodium citrate buffer (pH 4.5) via the tail vein. In the BG515 groups, we found increases in serum insulin levels, compared to the STZ-control group, but these data were not significant. In contrast, blood glucose and serum MDA concentrations decreased in the BG515 groups compare to the STZ-control group. At the 5th week, in all the BG515 administered groups, there were decreases in serum blood glucose levels compared to the STZ- control group, and this activity was very strong in the BG515-1 group at the 12th week. These results suggest that natural bio-complex compounds (BG515) may slightly suppress STZ-induced changes in serum MDA concentration via the maintenance of serum insulin levels, due to the prevention of $\beta-cell$ and glucagon destruction by STZ.

  • This study was examined 718 workers who had consistent blood pressure results in 2001 and 2002 general health examinations that were held at a work places managed by a health care agency in Seoul. Significant results are found as follows by analysing SPSS 11.0 on the result of self-recorded questionnaires investigated from Mar 1, 2003 to April 30, 2003. 1. A sampled healthy group and a sampled unhealthy group had significant differences in four variables out of possible nineteens that are sex, age, marriage and occupation. The unhealthy group had more males than females, more aged (over 50 years old) than youngers (under 50 years old), more married than singles, more manufacturing workers than non-manufacturing workers. In the case of systolic blood pressure, as the healthy group had 16.52mmHg while that of the other group had 149. 58mmHg, 33.06mmHg of difference between those groups were detected. In the case of diastolic blood pressure, 74.93mmHg of the healthy group and 96.53mmHg of the unhealthy group yielded 21.60mmHg of difference between them. This result implies that a guidance of health care is required to be aware of 20-30mmHg volatility in blood pressure rate or to understand and treat properly own blood pressure. as it is difficult to detect hypertension in early stage due to no initial symptom. According to the result. an establishment of management system of workers, companies and health care agencies is required for consist health care. 2. In terms of risky habits to health, the unhealthy group had more proportion of past smokers, over-twice-a-week drinkers, people with higher obesity rate. However, in terms of excercise, the proportion of regularly exercising people is higher in the unhealthy group while that of non-exercising people is higher in the healthy group. On the other hand. the average grade of health practicing behaviour in two groups are not significantly different as the health group had 3.00 out of possible 6.00 while the other had 3.10. This result means that as workers are not interested in health practicing behaviour. health promoting programmes must be developed in such a way of various method of motivations and incentives. Particularly this implies that distortional objectives of exercises should be readjusted through health guidance. 3. Systolic blood pressure in the healthy group can be explained by sex and the obesity rate while that in the unhealthy group can be explained by subjective health awareness and the obesity. Diastolic blood pressure in the healthy group can be explained by sex and the obesity rate like the former. The obesity rate was significant variable affecting the blood pressure of both groups, and particularly the effect to the unhealthy group was remarkably higher than that to the healthy group. Therefore, this research identified that the health care on the blood pressure of workers is not only limited to hypertension patients, but also extended to all workers. In order for consistent care, an establishment of management system of workers, companies and health care agencies is required.

  • The present study was designed to examine the effects of selenium(Se), vitamin E(Vit. E) and recombinant Bovine Somatotropin(rBST) administration on the selenium and vitamin E concentrations of blood in Hanwoo sires Hanwoo sires were randomly assigned to five groups; 1. control, 2. rBST, 0.09mg/kg body weight (BW) 3. Vit E, 1,500IU/kg BW, 4. Se 0.lmg/kg BW, 5. Vit E, 1.500IU plus Se 0.1mg/kg BW. rBST, Vit. E and Se for each experimental group were given 6 times at 15 days interval by intramuscular injection. Blood samples were collected 10 times for experimental periods, separated the serum by centrifugation, and stored at -7$0^{\circ}C$. Se and Vito E concentrations in blood were measured by fluorophotometer and HPLC. Se concentrations of blood in control, rBST, Vito E, Se and Se plus Vito E groups were 64.55, 65.50, 68.15, 73.11 and 74.09 ppb/$m\ell$, respectively. Se concentration in Vit. E plus Se group was significantly higher than in control and rBST groups (P<0.05), but Vito E group was not significantly different in control and rBST groups(P>0.05). The Vit. E concentrations of blood in control, rBST, Vit. E, Se and Se plus Vit. E groups were 2.27, 2.32, 2.80, 2.58 and 2.75 ppm/$m\ell$, respectively. Vit. E and Vit. E plus Se groups were slightly higher than those of any other groups, but not significantly difference in 외 I experimental groups(P<0.05). These results indicate that Se and Vit. E concentrations of blood were slightly increased with the injection of Se and Vit. E in Hanwoo sires.

  • The purpose of this study was to compare the anthropometry, blood pressure, blood lipid levels, and nutrient intakes in three groups: a group with an impaired fasting blood glucose (IFG) condition (62 males and 30 females); a group with normal blood glucose (73 males and 50 females); and a group with diabetes mellitus (DM) (79 males and 49 females). In male subjects, body mass index (BMI) and obesity index values were significantly higher in the IFG group than in normal and DM groups, but waist/hip ratio (WHR), systolic blood pressure, and diastolic blood pressure were not significantly different from those of the DM group. In female subjects, there was no difference in body weight, BMI, obesity index and WHR values between the IFG and the DM groups. The prevalence of obesity in the IFG group (males 43.6%, females 76.7%) was the highest among the three groups. The percentage of high SBP (40.0%) and high DBP (52.0%) in male subjects of the IFG group was significantly greater than in the DM group or the normal group. In the male subjects, the serum triglyceride concentration was significantly higher in the DM group than in the normal and IFG groups. There was no difference in various nutrient intakes(energy, carbohydrate, protein, fat, calcium, iron, vitamin A and cholesterol) among the three groups. In male subjects, the percentage of energy intake from alcohol was higher in the IFG group (7.0%) than that of the normal (4.5%) and the DM (5.6%) groups. The fasting blood glucose level had a positive correlation with WHR, TG, the athrogenic index and LDL-cholesterol/HDL-cholesterol. This study suggested that the IFG group had a higher obesity index, BMI, blood pressure and serum lipid levels (TG, cholesterol) than the normal or the DM group; furthermore, the IFG group had higher levels of alcohol intake and habits of taking unbalanced diets. Therefore, guidelines for IFG group should emphasize weight control, diet therapy, physical activities and regular balanced diets, in order to prevent diabetes in this group.

  • Objective: The aim of this study was to investigate the correlation between atopic dermatitis and a comprehensive diagnosis of Qi Blood Water in children with or without atopic dermatitis. Methods: We surveyed 206 children in Seoul Jungnang-gu nursery by reviewing the questionnaires following a medical examination. Comprehensive diagnosis of Qi Blood Water was investigated by questionnaires and composition scores and total scores were calculated from the symptom scores. Atopic dermatitis was diagnosed by ophthalmo.otolaryngo.dermatologist and atopic dermatitis symptom was measured by a Visual analogue scale(VAS). Comparisons between the atopic and non-atopic groups were made based on the atopic dermatitis symptom scale, composition scores and total scores. Results : 1. Of the 206 patients, 153(74.27%) were included in the non-atopic group, while 53(25.73%) were included in the atopic group. There was no difference in average age between the two groups. 2. The atopic dermatitis symptom scale of atopic group(3.21$\pm$2.018) was significantly higher than that of non-atopic group(0.04$\pm$0.28). 3. Qi deficiency, Qi stagnation, Blood stasis and Water congestion scores and the total scores of the atopic group were higher than those of the non-atopic group, but it was not significant. 4. The Qi regurgitation and Blood deficiency scores of atopic group were significantly higher than those of the non-atopic group. 5. There was a highly significant correlation between the atopic dermatitis symptom scale and Qi regurgitation scores, and between the atopic dermatitis symptom scale and Blood deficiency scores. Conclusion : Atopic dermatitis seems to have a special feature reflecting the state of comprehensive diagnosis of Qi regurgitation and Blood deficiency in children.

  • Objective:To evaluate the performance of combined quantitative analysis of thyroid blood flow and static imaging data in the differential diagnosis of thyroid nodules. Method: Thyroid blood flow and static imaging were performed in 165 patients with thyroid nodules. Patients were divided into a benign thyroid nodule group (BTN, n=135) and a malignant thyroid nodule group (MTN, n=30) based on the results of post-surgical pathologic examination. Carotid artery thyroid transit times (CTTT), perfusion ratio of thyroid nodule blood/thyroid blood (TNB/TB), and perfusion ratio of thyroid nodule blood/carotid artery blood (TNB/CAB) were measured using thyroid blood flow imaging. The ratios between thyroid nodule and ipsilateral submandibular gland (TN/SG) and thyroid nodule and normal thyroid tissue (TN/T) were measured from thyroid static imaging. The differences between the BTN and MTN groups were compared. Results: 1) CTTT was markedly lower in the MTN group than the BTN group, the difference being statistically significant. 2) TNB/TB and TNB/CAB were both significantly higher in MTN than BTN groups. 3) TN/T was significantly lower in MTN group than BTN group. 4) TN/SG was lower in MTN group than BTN group, but the difference was not statistically significant. 5) Using the combination of CTTT and TN/T, the sensitivity, specificity and accuracy were 93.1%, 95.3% and 94.9% respectively for the diagnosis of MTN. Using the combination of CTTT, TNB/TB and TN/T, the sensitivity, specificity and accuracy changed to 89.7%, 100%, and 98.1% respectively. 6) Correlation analysis demonstrated a significant correlation between TN/T and TNB/TB (r=-0.384, P=0.036) and TNB/CAB (r=-0.466, P=0.009) in the MTN group. Conclusion: The combination of quantitative markers from thyroid blood flow and thyroid static imaging had high specificity and accuracy in differential diagnosis of benign and malignant thyroid nodules, thus providing an important imaging diagnostic approach.
