  • Whatever a surgeon choose aortic prosthesis in aortic stenosis, it will always provoke some degree of obstruction to flow due to its smaller effective orifice area to tissue annulus. Occasionally, we meet small aortic annulus to his or her body surface area in aortic valve replacement. The small annulus remains a problem in that both tissue and mechanical prosthesis have significant pressure gradients between LV and aorta in resting or exercising states. In these circumstances, diverse surgical procedures, such as tilting disc prosthesis, supraannular position of aortic prosthesis, and enlargement of aortic root [including aortoventriculoplasty, translocation of aortic valve, & double outlet of LV by valved conduit], were applied. We experienced one case of aortic stenosis with small aortic annulus. Systolic pressure gradients between LV & aorta were 90 mmHg. Diameter of annulus was 19 mm. So we performed patch enlargement of aortic root by Manouguian and AVR with St. Jude medical valve 23 mm.

  • We report the successful use of Nifedipine in the treatment of acute pulmonary hypertension in an young child after a cardiac operation. This patient had undergone patch closure of large ventricular septal defect. She had signs of severe pulmonary artery hypertension unresponsive to hyperventilation, oxygenation, sedation, and a myriad of vas-oactive drugs. Nifedipine, 0.3mg /kg every 4 hours, effectively treated her pulmonary artery hypertension and allowed for a smooth postoperative course and positive outcome. The drug lowered systemic diastolic pressure, but not systolic pressure.

  • Clonidine, an antihypertensive drug, stimulates postsynaptic alpha-2 adrenergic receptors in the central nervous system and lowers arterial pressure through the effects on both cardiac output and peripheral resistance. However, many patients experience that sedation and xerostomia occur upon oral administration of clonidine. These side effects are due to high plasma peak concentration and can be avoided when clonidine is given transdermally. In this study, we tested the antihypertensive effects of trandermal administration of clonidine patch on spontaneously hypertensive rat (SHR) which is a model animal for human essential hypertension. Forty eight SHR (male) were divided into six groups according to the dose levels, respectively. After transdermal administration of clonidine patch of each dose, systolic blood pressure and heart rate were measured. Clonidine patch produced maximal antihypertensive and bradycardiac effects 48 hrs after administration and antihypertensive effects showed dose-dependency. We suggest that antihypertensive effects of clonidine patch are similar to those of orally given clonidine and clonidine patch can be used instead of clonidine tablet.

  • Purpose: This study evaluates the efficacy of a Self-Care Reinforcement Program (SCRP) based on the Selection Optimization Compensation (SOC) model, in socially vulnerable elderly women with metabolic syndrome. Methods: This study adopts a pretest-posttest nonequivalent control group design. The participants were 64 socially vulnerable elderly Korean women with metabolic syndrome (experimental group: 31, control group: 33). Participants' body composition analysis, nutrient intake, risk factors of metabolic syndrome, depressive symptoms, and social network were measured. Data were analyzed with an independent t-test; statistical significance levels were set at p<.05. The SCRP, including metabolic syndrome education, nutritional education, exercise, and social network, was performed three times a week for 8 weeks. Results: There were statistically significant differences between the experimental and control groups in terms of systolic blood pressure, diastolic pressure, fasting blood sugar, triglycerides, sodium intake, depressive symptoms, and social networks. Conclusion: The SCRP is effective and can be recommended as a community health nursing intervention for socially vulnerable elderly women with metabolic syndrome.

  • Purpose: This study was conducted to examine factors associated with obesity among Korean adolescents. Methods: The participants were 436 Korean adolescents aged 12~18 years who took part in the seventh Korea National Health and Nutrition Examination Survey (2016). The data were analyzed by descriptive statistics, the $x^2$ test, one-way analysis of variance, and multinomial logistic regression using complex sample analysis. Results: Among the participants, 9.7% were classified as being obese, and 11.9% as being overweight. Several health parameters, including systolic blood pressure, diastolic blood pressure, waist circumference, and triglyceride, fasting blood sugar, and alanine aminotransferase levels, varied according to obesity. Distorted perceptions of body shape showed a significant negative association with overweight, and carbohydrate intake was negatively associated with obesity. Conclusion: These findings indicate that obesity in Korean adolescents was associated with lifestyle and health parameters. Therefore, intervention programs for obese or overweight adolescents should focus on preventing them from developing health problems.

  • A number of substituted furodiketochroman derivatives ($lll_{a-f}$) have been synthesized by fusion of aromatic aldehydes with 5-hydroxybergapten and 5-hydroxyisopimpinellin. On the other hand, when the reaction was carried out in a solvent, the corresponding bis-furoccumarin derivatives ($lV_{c-n}$) were obtained. The anticoagulant effect of compounds $lll_{a,b,d}$ and $lv_{b,c,f,g,i,k}$ was tested. They failed to demonstrate any significant effect. The effect of the tested compounds on the arterial blood pressure was studied. Compounds $lV_c$, $lll_d$, $lll_b$, $lV_b$, $lV_k$ and $lV_i$ showed lowering effects on the normal systolic blooc pressure of anaesthetized rats in a decreasing manner.

  • The prevalence of obesity has been increasing worldwide. Several dietary treatments have been suggested to control weight, and recent guidelines recommend individualizing the composition of macronutrients. Carbohydrates are the most important nutrients in meals, and carbohydrate restriction is a dietary strategy that promotes weight loss. A low-carbohydrate diet is effective for short-term weight loss and can help improve glycated hemoglobin, systolic blood pressure, diastolic blood pressure, and triglyceride levels; however, the long-term effects and safety of this diet remains doubtful. In the short term, there is a risk of gastrointestinal symptoms such as vomiting, diarrhea, constipation, and gastroesophageal reflux, and type 1 diabetes patients are at risk of severe hypoglycemia, while in the long term, it can lead to malnutrition and decreased exercise capacity. Thus, rather than limiting the intake of carbohydrates, it is important to limit the intake of refined grains, sugar, honey, syrup, and sweetened beverages while maintaining the planned carbohydrate intake rate and improving meal quality.

  • Background: Vasodilatory shock after cardiac surgery may result from the vasopressin deficiency following cardio-pulmonary bypass and sepsis, which did not respond to usual intravenous inotropes. In contrast to the adult patients, the effectiveness of vasopressin for vasodilatory shock in children has not been known well and so we reviewed our experience of vasopressin therapy in the small babies with a cardiac disease. Material and Method: Between February and August 2003, intravenous vasopressin was administrated in 6 patients for vasodilatory shock despite being supported on intravenous inotropes after cardiac surgery. Median age at operation was 25 days old (ranges; 2∼41 days) and median body weight was 2,870 grams (ranges; 900∼3,530 grams). Preoperative diag-noses were complete transposition of the great arteries in 2 patients, hypoplastic left heart syndrome in 1, Fallot type double-outlet right ventricle in 1, aortic coarctation with severe atrioventricular valve regurgitation in 1, and total anomalous pulmonary venous return in 1. Total repair and palliative repair were undertaken in each 3 patient. Result: Most patients showed vasodilatory shock not responding to the inotropes and required the vasopressin therapy within 24 hours after cardiac surgery and its readministration for septic shock. The dosing range for vasopressin was 0.0002∼0.008 unit/kg/minute with a median total time of its administration of 59 hours (ranges; 26∼140 hours). Systolic blood pressure before, 1 hour, and 6 hours after its administration were 42.7$\pm$7.4 mmHg, 53.7$\pm$11.4 mmHg, and 56.3$\pm$13.4 mmHg, respectively, which shows a significant increase in systolic blood pressure (systolic pressure 1hour and 6 hours after the administration compared to before the administration; p=0.042 in all). Inotropic indexes before, 6 hour, and 12 hours after its administration were 32.3$\pm$7.2, 21.0$\pm$8.4, and 21.2$\pm$8.9, respectively, which reveals a significant decrease in inotropic index (inotropic indexes 6 hour and 12 hours after the administration compared to before the administration; p=0.027 in all). Significant metabolic acidosis and decreased urine output related to systemic hypoperfusion were not found after vasopressin admin- istration. Conclusion: In young children suffering from vasodilatory shock not responding to common inotropes despite normal ventricular contractility, intravenous vasopressin reveals to be an effective vasoconstrictor to increase systolic blood pressure and to mitigate the complications related to higher doses of inotropes.

  • This study was carried out to investigate the effect of antihypertensive peptides originating from marine proteins on ACE inhibitory activity and systolic blood pressure in spontaneously hypertensive rats (SHR). Sixteen male SHR (SHR/NCrj) weighing approximately 270 g were randomly divided into few experimental groups based on diet: C (control), A (anchovy), P (pollack) and M (mackerel). The final body weights of P and M groups were higher, than those of C and A groups, but difference was not significant. Average reference blood pressure (RBP) was 224 mmHg at 12 weeks old. Compared with RBP, final systolic blood pressure of the marine peptide oops after 28 days of feeding with anchovy, pollack and mackerel fractions by gavage was decreased by 9.0% (A), 10.2% (P) and 14.3% (M), respectively, but was not different in C. Especially, final blood pressure of M was lower by 32 mmHg than RBP. These results suggested that peptide originated from mackerel hydrolysate was considered to have an antihypertensive fraction as effective lowering of blood pressure in SHR.

  • This study was carried out to investigate the effect of Gastrodiae elata Blume fractions on systolic blood pressure and serum lipid profiles in spontaneously hypertensive rats (SHR/NCrj) fed high fat diet. Twenty-four males SHR weighing approximately 160 g were randomly divided into four groups; A (low molecule, GR-1), B (polysaccharide, GR-2), C (protein, GR-3) fractions of G. elata Blume, respectively, and D (high fat diet as control). After orally tube feeding the fractions of G. elata Blume, there were no differences in final body weights among the treatment groups. Diet intake was somewhat high in the control group (D), but there were no significant differences in feed efficiency ratios. In terms of serum lipid profiles, total-cholesterol level was statistically higher in the control group (D) than in G. elata Blume fraction groups (p<0.05). Triglyceride levels of low molecule (A) and polysaccharide (B) groups were lower by 16% and 11%, respectively than that of the control group (D). HDL-cholesterol level was remarkably higher (p<0.05), whereas LDL-cholesterol level was significantly lower (by 25%) in the group B as compared to the control group (D). Atherogenic index (AI) of G. elata Blume fraction groups were significantly lower than in the control group (p<0.05). Reference blood pressure (RBP) showed an average of $180\sim190mmHg$ at 8 weeks old after 3 weeks on feeding high fat diet. Compared with RBP, final blood pressure of treatment groups (35 days after feeding the fractions of G. elata Blume gractions) were decreased by 1.7% (A), 5.5% (B) and 3.6% (C), respectively, but the control group (D) contrarily showed an increase of 2.6%. Especially, final systolic blood pressure of the polysaccharide group (B) was lower by 22 mmHg than that of the control group (D). From these findings, it can be suggested that polysaccharide fraction may improve blood serum lipids and should be considered as effective in lowering of blood pressure.
