  • The purpose of this study was to analyze the nutritional status and dietary habits in predialysis patients of chronic renal failure(CRF). The patients group was composed of total 35 persons with chronic renal failure(diabetes exclusion), male 20, female 15 who were treated in the kidney internal department and the control group also composed of 35 persons, male 18, female 17 who were classified as normal by the medical examination. Their dietary habits, nutritional status and nutritional knowledge were investigated from two general hospitals in Inchon, middle of this year 2002. There were 31.4% of low weight patients (BMI below 20), 77.1% of anemia patients (serum hemoglobin below 12g/㎗), 6S.6% of hypertension patients with diastolic blood pressure over 90mmHg, 80% with systolic blood pressure over 140mmHg, 20% of hypercholesterolemia patients (serum cholesterol over 230mg/㎗), and 22.9% of hyperlipemia patients (serum triglyceride over 200mg/㎗). The cardiovascular disease seemed to be caused by the abnormality of lipid metabolism. The possibility of the bone disease was shown from patients of hyperphosphatemia (serum phosphorus over 4.7mg/㎗, 22.9%) and hypocalcemia (serum calcium below 8.4mg/㎗, 25.7%). Intake of insufficient calories which was caused by the lack of appetite affected on the nutritional status. The intake of most nutrients was not significantly different from the RDA for Koreans. Consequently, the patient groups took a lot of salt even after the diagnosis of CRF. But patients ate 6.lg of salt which were more than the recommended amount 2∼4g for patients with CRF. The patient groups, who had the experiences of nutritional counselling, had significantly higher nutritional knowledge related to CRF than control group. Unfortunately, patients could not have enough chances for nutritional counselling by the nutritionist even though they needed the nutritional informations and dietetic treatments. The continuous research is expected with regard to the detail plan for the improvement of nutritional support and the nutritional counselling because it is important to decide the requirements of nutrients for patients with kidney disease, considering the kidney function and status of nutrition.

  • Orthostatic hypotension (OH) is defined by a 20-mm Hg difference of systolic blood pressure (dtSBP) and/or a 10-mm Hg difference of diastolic blood pressure (dtDBP) between supine and standing, and OH is associated with a failure of the cardiovascular reflex to maintain blood pressure on standing from a supine position. To understand the underlying genetic factors for OH traits (OH, dtSBP, and dtDBP), genome-wide association studies (GWASs) using 333,651 single nucleotide polymorphisms (SNPs) were conducted separately for two population-based cohorts, Ansung (n = 3,173) and Ansan (n = 3,255). We identified 8 SNPs (5 SNPs for dtSBP and 3 SNPs for dtDBP) that were repeatedly associated in both the Ansung and Ansan cohorts and had p-values of < $1{\times}10^{-5}$ in the meta-analysis. Unfortunately, the SNPs of the OH case control GWAS did not pass our p-value criteria. Four of 8 SNPs were located in the intergenic region of chromosome 2, and the nearest gene (CTNNA2) was located at 1 Mb of distance. CTNNA2 is a linker between cadherin adhesion receptors and the actin cytoskeleton and is essential for stabilizing dendritic spines in rodent hippocampal neurons. Although there is no report about the function in blood pressure regulation, hippocampal neurons interact primarily with the autonomic nervous system and might be related to OH. The remaining SNPs, rs7098785 of dtSBP trait and rs6892553, rs16887217, and rs4959677 of dtDBP trait were located in the PIK3AP1 intron, ACTBL2-3' flanking, STAR intron, and intergenic region, respectively, but there was no clear functional link to blood pressure regulation.

  • The main purpose of this study was to evaluate the effect of a Rhythmical Exercise Program(REP) on physiological functions such as muscle strength, blood pressure, pulse, flexibility and body fat in the elderly. The research employed a non-equivalent control group pre-post test quasi experimental design. REP consisted of 45 minutes of dance, 3 times a week for 10 weeks. The formulated hypothesis were examined using the non-parametric statistics; Wilcoxon Signed rank sum test and Mann-Whitney test. The results are as follows; 1. The upper muscle strength and lower muscle strength of the experimental group were significantly higher than those of the control group following the REP(P<.0 5). And the Period of REP affected the muscle strength; the longer the exercise period, the stronger the muscle strength became. 2. The systolic blood pressure of the experimental group was significantly lower than that of the control group following the REP(p<.05). But there was no significant difference in the diastolic blood pressure between the experimental and control groups. The period of REP affected only systolic pressure; the longer the exercise period, the lower the systolic pressure became. 3. There was no significant difference in heart rate between the experimental and control groups, following the exercise period. 4. The flexibility of the experimental group was significantly higher than those of the control group following the REP(p<.01). And the period of REP affected flexibility; the longer the exercise period, the higher the flexibility(p<.05) became. 5. There was no significant difference of body fat between the experimental and control groups. The body fat of the experimental groups was significantly lower only 10 weeks after exercise(p<.01). Based on these results, it is suggested that rhythmical exercise program improves muscle strength, systolic pressure, and flexibility in the elderly.

  • The purpose of this study was to investigate the relationship between body fat and risk factors of chronic diseases in obese children and eventually to contribute to the prevention and treatment of childhood obesity. Anthropometric parameters such as height, weight, skinfold thickness, circumferences, body fat content were measured in 55 obese subjects of age 5-20. Blood pressure, serum components, daily food intakes were also considered. The average age of the subjects was 12.5$\pm$3.3yrs and the mean obesity index was 64.7$\pm$21.3%. The average percentage of body fat was 35.6$\pm$5.4% and the mean weight of lean body mass was 45.3$\pm$13.9kg. Mean total muscle weight of the subjects was estimated to be 34.11$\pm$1.3kg. The mean systolic and diastolic blood pressures of the obese were 134.8$\pm$15.8mmHg and 69.6$\pm$11.6mgHg respectively. The concentrations fo serum triglyceride, total cholersterol, HDL-cholesterol, LDL-cholesterol were estimated to be 246.0$\pm$136.4mg/dl, 257.0$\pm$54.3mg/dl, 48.2$\pm$13.1mg/dl and 158.9$\pm$53.5mg/이 respectively. The concentrations of serum GOT and GPT were 34.6$\pm$17.1U/L and 24.7$\pm$15.3U/L. The mean content of uric acid is serum was 6.2$\pm$1.9mg/dl. Of these 55 children, 82% has hyperlipidemia, 26% was abnormal liver function and 24% was hyperuricemia. One patient was diabetic. Eighty seven% of them have developed more than one complications.

  • Background: Tourniquet pain has important impacts on anesthesia. Tourniquet pain and accompanying cardiovascular changes are important factors that make patients in distress during anesthesia. As tourniquet pain may be modified by anesthesia, a study on the changes in the neural functions by tourniquet inflation in normal volunteers is important. Methods: Time-dependent changes in tourniquet pain, heart rate, phantom limb sensation, motor function, pain to pressure on upper extremity of 10 healthy and unpremedied volunteers were measured. Each parameter were measured every 5 minutes starting from 10 minutes before inflation to 15 minutes after deflation of tourniquet. Tourniquet was deflated when the subject felt unbearable pain (score 100 with visual analog scale). Results: Subjects manifested time-dependent pain responses to tourniquet inflation, characterized by increase in VAS, systolic and diastolic blood pressure. Mean duration of tourniquet inflation was 36.4 minutes, volunteers experienced motor paralysis at 27.6 minutes and sensory loss at 33.1 minutes. Pain to pressure decreased over time in both arms. The degree of decrease was greater in the arm on which tourniquet was applied than that in the non-applied arm. Phantom limb sensation occurred in 3 subjects. Conclusions: This study demonstrated dynamic changes in the neural functions during tourniquet inflation period. Tourniquet-induced pain and resultant hypertension occurred in all subjects. Appropriate anesthetic management is needed for the surgery using tourniquet.

  • Background and Objectives : There were few literatures about the relationship between upper airway disorders and cardiovascular risk factors such as hypertension, although an association between impaired lower respiratory function and cardiovascular alterations was often reported. Our purpose was to assess the relationships between chronic sinusitis and hypertension. Materials and Methods : Three hundred subjects with bilateral chronic sinusitis who underwent functional endoscopic sinus surgery between 2015and 2017 were evaluated. Six hundred forty subjects without any nasal diseases were enrolled as a control group. Blood pressure and body mass index (BMI) were measured using a standardized method, and subjects were asked about current use of any antihypertensive medication, history of diabetes, smoking and alcohol drinking habits.Sinusitis group was assessed by nasal endoscopic examination, paranasal sinus CT scan and allergy test. Results : Average systolic and diastolic blood pressures were statistically significantly higher in subjects with sinusitis than control group. Chronic rhinosinusitis was associated with a 1.415-fold (95% confidence interval 1.053-1.930) increased hazard of hypertension after multivariate adjustment. Conclusions : These results suggest that sinusitis is associated with high blood pressure. Therefore patients with sinusitis may need special attention for blood pressure control. Further studies need to be performed to elucidate the pathogenesis behind such associations.

  • Background: Korean Red Ginseng (Panax ginseng) has been shown to exert antihypertensive effects. In particular, ginsenoside Rg3 is thought to be a potent modulator of vascular function. The present study was performed to examine the antihypertensive efficacy of Korean Red Ginseng (KRG) extract and Rg3-enriched KRG (REKRG) extract. Methods: Spontaneously hypertensive rats (SHRs) andWistar-Kyoto rats (WKYs) were divided into six groups (WKY control, WKY-KRG, WKY-REKRG, SHR control, SHR-KRG, and SHRREKRG), and systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at the carotid artery, followed by injection of 3mg/kg KRG or 3mg/kg REKRG. Results: REKRG treatment significantly decreased SBP and DBP 3hours post-treatment in the SHR group compared with SHR control group. However, SBP and DBP were not significantly different in KRG-treated SHRs compared with control SHRs. REKRG treatment did not significantly alter SBP or DBP 3hours post-treatment in the WKY group compared with WKY control group. Similarly, there were no differences in SBP or DBP with KRG treatment in the WKY group and WKY control group. Both KRG and REKRG increased endothelial nitric oxide synthase phosphorylation levels in the aorta, and the increases in endothelial nitric oxide synthase phosphorylation levels by REKRG treatment were higher than those with KRG treatment. Similarly, nitric oxide production in plasma from WKYs and SHRs was also increased by both KRG and REKRG. Conclusion: These results suggest that REKRG has a more beneficial effect on blood pressure control than KRG in SHRs.
