1 . Experimental study Preventive effect of Korea Red Ginseng (KPG) on hypertensive retinal arteriolosis in rabbits was studied. The results as follows: Blood pressure: Hypertensive group (B) was obviously raised up in comparing with that in normal group(A) and in hypertension + KRG group(C). Ocular fundus:Changes in B group including the retinal arteriospasm, crossing arterioveous, exudation and edema. But C group showed lightly. Light microscope: HE stained vascular damage in retina including thickness hyalimisation, execdates and edema Electron microscope: The endothelial cells were arranged irregularly, different shape and showed cytoplasm loose and vacuole. Immunohistochemistry: Ginseng can regulating endothelin-1, angiotension-ll, endothelium grow factor expre,j,iion and secreation in retinal blood clrultion. 2. ClinicAl Study 66 of hypertensive patients (42 men, 23 women,48-68 years old)and 20 normal person (7 men, 13 women,47-68 years old) were administrated(p.0.) by HRG (3g per day for 6 weeks). The results showed that marked effective rate and total effective rate were 53cyo and 60.6alo respectively and no severe side effects were found. The above results suggest that Ginseng have a difinite hypotensive effect and a role of preventing hyperfine sloe arteriosclerosis.

This study was done to research the general information, causes of stroke, risk factors, complications during admission of geriatric CVA inpatients. We retrospectively studied 208 above 65 years old geriatric CVA inpatients treated in Ajou university hospital from 1994 to 2003 by medical record. These were divided into two groups by following years. We were gathered information about sex, onset age, cause of stroke, number of stroke, complications, housing, family, insurance, smoking, alcohol. Most of incidence of the stroke was noted in the group of young old age (65~74 years old) and old age (75~84 years old). The occurrence rate of male stroke (38.5%) was less than of female stroke (61.5%) and the ratio of male to female was 1:1.6. The occurrence rate of ischemic stroke (72.6%) was higher than of hemorrhagic stroke. The occurrence rate of ischemic stroke increased more and more at the late stage. The most common risk factors for stroke was hypertension and complications during hospitalization were neurogenic bowl and bladder. These results of epidemiologic study may help above 65 years old geriatric CVA early treatment and prevention, rehabilitation and use basic data for multiple prospective study using stroke registry.

This study was attempted to investigate the action of debrisoquine, a sympathetic blocking agent presently employed in treating hypertension, on renal function and to elucidate the mechanism of its action. Debrisoquine, given intravenously, elicited increased urine flow, osmolar and free water clearances, along with marked increases in excretion of both sodium and potassium. Glomerular filtration rate also increased, but renal plasma flow tended to decrease, so that the filtration fraction tended to increase. Rates of reabsorption of sodium and potassium in renal tubules were also significantly diminished. The diuresis induced by debrisoquine was completely blocked by treatment with phentolamine and reserpine, and also markedly inhibited by acute renal denervation. Debrisoquine, when injected directly into a renal artery, produced antidiuretic effect and a reduction in urinary excretion of sodium and potassium, along with diminished renal plasma flow and increased filtration fraction. The above observations indicate that debrisoquine, when given intravenously, induces diuresis in the dog as a result of both diminished tubular reabsorption of electrolytes and of renal hemodynamic changes, which seem to be related to its inhibitory action of catecholamine-release from the sympathetic nerve endings.

Cardiovascular diseases are the leading cause of death and disability in Korea. Their risk factors can be classified as either modifiable or nonmodifiable and among modifiable factors are high bood pressure, elevated blood cholesterol, obesity and cigarette smoking. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in a rural community and to get basic data for the development of a community-based rick reduction intervention program. Evaluation involved population-based, cross-sectional samples of adult residents in a rurual community. We measured blood pressure, body fat percent by bioelectric impedance fatness analyzer and serum cholesterol and interviewed adult residents over 20-year-old age. Blood pressure was checked twice and hypertension was classified by the sixth report of the Joint National Committee on Detection. Evaluation, and Treatment of High Blood Pressure. The Cutpoints for high blood cholesterol was used National Cholesterol Treatment Guidelines and those for obesity was 25% in male. 30% in female. The results were as follows: 1. Prevalence of definitive hypertension was 59.7% in males and 54.4% in female. 2. Prevalence of hypercholesterolemia was 14.3% in male and 18.2% in female. 3. Prevalence of obese was 10.7% in male and 41.1% in female. 4. Among definitive hypertension, hypercholesterolemia, and obesity 52.1% possessed one risk factor, 12.6% two risk factors and 2.5% three risk factors in males. In females 41.4% possessed one risk factor and 27.6%. 5.7% respectively. 5. The smoking rate was 65.8% in males and 5.2% in females. Our results are used effectively for the community-based intervention towards cardiovascukr diseases risk reduction. However, because of limitations in our study design, further datas are needed including other risk factors and in-person clinical datas.

Objective : The treatment of malignant posttraumatic brain swelling remains a frustrating endeavor for neurosurgeon. Mortality and morbidity rates remain high depite advances in medical treatment of increased intracranial pressure. If conventional therapy fails in patients suffering from intracranial hypertension, there is only small number of second-tier option left including decompressive craniectomy. The role of decompressive craniectomy in posttraumatic brain swelling remains controversial. We assessed the efficacy and indications of decompressive craniectomy. Methods : The authors performed decompressive bifrontotemporal craniectomy in 22 patients with malignant posttraumatic brain swelling. Epidural pressure monotoring was performed in all patients. The clnical data and surgical outcomes were reviewed retrospectively. Result : The favorable outcome(GOS score 4-5) was 59%(13 of 22 patients), whereas the mortality rate was 32% (7 of 22 patients). Two patients(9%) remained in severely disabled state. Increased rate of favorable outcome was seen in the patients who had 8 or more of GCS score at admission and exhibited B wave in ICP monitoring and who showed steady state or slow deterioration in clinical course. Conclusion : If conservative therapy fails, decompressive bifrontotemporal craniectomy should be considered in the management of malignant posttraumatic brain swelling before irreversible ischemic brain damage occur.

Although re-expansion pulmonary edema (RPE) is rare (incidence rate <1%), it is associated with a mortality rate of >20%; therefore, early diagnosis and treatment are important. We report a case of RPE following chest tube insertion in a patient with spontaneous pneumothorax. We have specifically focused on the mechanism underlying RPE and the possible etiology. An 82-year-old man with a history of chronic anemia, chronic obstructive pulmonary disease, diabetes mellitus, and hypertension was referred to the emergency department for management of recurrent right-sided pneumothorax. We performed emergency closed thoracostomy for suspected tension pneumothorax, which led to stabilization of the patient's vital signs; however, he coughed up frothy pink sputum accompanied by severe right-sided chest pain 30 min postoperatively. The patient showed new-onset right pulmonary consolidation on chest radiography, as well as desaturation, tachycardia, and tachypnea and was diagnosed with RPE. He was transferred to the intensive care unit for mechanical ventilation and supportive treatment using diuretics, ionotropic agents, and prophylactic antibiotics. RPE gradually resolved, and the patient was extubated 3 days after admission. He has not experienced recurrent pneumothorax or pulmonary disease for 4 months. We emphasize the importance of RPE prevention and that aggressive ventilator care and supportive treatment can effectively treat RPE following an accurate understanding of the underlying pathogenetic mechanisms and risk factors.

Objective : This study was carried out to investigate the effects of DDT on the brain damage and hypertension. Methods : We observed the effect of Dodamtang(DDT) extract on KCN-induced coma, focal brain ischemia by MCA occlusion, cytotoxicity and protection of PC12 cells and B103 cells induced by amyloid ${\beta}$ protein(25-35). To prove the effect of DDT as a blood pressure depressant, we measured aldosterone, renin activity, catecholamine, sodium and NO density using the seperated blood plasma. Results : DDT showed a protective effect on cytotoxicity of PC12 cells and B103 cells induced by amyloid ${\beta}$ protein(25-35) in a dose dependent manner and proved the significant abridgement of brain ischemic area and edema induced by MCA occlusion, a critical decrease of neurologic deficitic grade in the fore-limbs. DDT didn't reduce the duration of KCN(1.87mg/kg iv.)-induced coma and prolonged the survival rate in the case of KCN(3.0mg/kg iv.)-induced coma by the ratio of 20%. While DDT increased the value of NO in SHR, it significantly decreased the blood pressure of SHR and the value of aldosterone& epinephrine in SHR. Conclusions : These results suggested that DDT might be usefully applied for treatment of hypertension, cerebral infarction, and brain damage.

The purpose of this study is to investigate the blood pressure reducing effect of Qi-Ju-Di-Huang-Wan (QJDHW) in adults with essential hypertension by using methods of systemic review and meta-analysis. Major search engines, such as PubMed, EMBASE, Cochrane library, Web of Science, CNKI, CiNii, J-STAGE, KISS, NDSL, RISS, OASIS, DBpia and so on, were used. The search period we used is from the start date of the search engine to October 30, 2016 and no language limits were placed. Randomized controlled trials using QJDHW in adults with essential hypertension were searched and extracted by two independent researchers. Meta-analysis was performed on outcome variables of the total effective rate (TER), systolic blood pressure (SBP) and diastolic blood pressure (DBP). Risk of bias (RoB) of Cochrane was used to assess methodological quality. Thirteen studies were finally selected. We observed that the combined treatment of QJDHW and antihypertensive drug had 3.6 times the odds ratio of TER for blood pressure lowering than a single use of an antihypertensive drug. Additionally, mean differences of SBP and DBP were -8.88 mmHg (95% Confidential Interval (CI) -12.77 mmHg, -5.00 mmHg, P<0.00001), -7.09 mmHg (95% CI -9.93, -4.25, P <0.00001), respectively. Single use of QJDHW did not reduce blood pressure more than an antihypertensive drug. All items of RoB were unclear and the methodological quality was low. Our analysis suggests that the combination of QJDHW and antihypertensive drugs may be more effective in reducing blood pressure than a single antihypertensive drug. But due to low methodological quality, careful interpretation will be needed and systematic long-term clinical trials will be required.

배경: 만성 폐동맥 색전증에 의한 폐동맥고혈압은 내막제거술에 의해 효과적으로 치료할 수 있는 질환으로서 본원에서의 수술 경험을 분석하여 질환에 대한 이해와 이를 토대로 향후 수술적 예후를 향상시킬 수 있는 방안에 대해 알아보고자 한다. 대상 및 방법: 1998년 1월부터 2008년 3월까지 본원에서 만성 폐동맥 색전증에 의한 폐동맥 고혈압으로 내막제거술을 받은 20명을 대상으로 후향적으로 분석하였다. 주증상은 주로 호흡곤란이었고 페동맥 색전증의 원인으로는 심부혈전증 11명(55%)이 가장 많았다. 17명(85%)의 환자에서 하대정맥 필터를 삽입하였다. 수술은 완전 순환 정지하(n=13) 또는 low flow (n=7)를 유지한 상태에서 시행하였고 수술 전 삼첨판 폐쇄부전이 grade IV/IV 이상인 환자들 중 6명(66%)에서 삼첨판륜 성형술을 함께 시행하였다. 평균 추적 관찰 기간은 $45{\pm}32$개월이었다. 결과 University of California, San Diego (UCSD)분류에 따른 폐동맥 색전증의 종류는 type I이 4명 (20%), type II, III가 각각 8명(40%)씩이었고 우심실 수축기압은 수술 전 평균 $77{\pm}29$ mmHg에서 수술 직후 $37{\pm}19$ mmHg로 감소하였으며(p<0.001) 삼첨판 폐쇄부전의 정도 및 NYHA functional class 모두 수술 후 호전을 보였다. 재관류 손상은 7예(35%)로 UCSD type I, II인 환자군에 비해 type III인 환자에서 재관류 손상의 발생률이 더 높았고(25% vs 50%, p=0.25) 중환자실 재원기간도 길었다($5{\pm}2$일 vs $9{\pm}7$일, p=0.07). 조기사망은 2명(10%)이었고 만기사망은 기저질환의 악화 1명, 폐동맥 색전증의 재발 1명, 그리고 지속된 폐동맥 고혈압 1명, 모두 3명(15%)이었다. 결론: 내막제거술은 만성 폐동맥 색전증의 효과적인 수술적 치료 방법으로서 정확한 진단을 통해 적극적으로 시행하여야 하며, 수술적 예후를 향상시킬 수 있도록 더욱 노력해야 할 것이다.
