본 연구는 뇌혈관질환의 위험요인을 규명하고, 특히 혈청 콜레스테롤 값 및 코골음과 뇌혈관질환과의 관련성을 검정하기 위하여 시도된 짝지은 병원 환자-대조군 연구이다. 환자군인 뇌혈관질환군은 1993년 12월부터 1995년 3월까지(16개월간) 경상대학교 병원 신경과에 처음 입원하는 환자로 뇌전산화 단층촬영으로 확진되는 뇌경색 74명, 뇌출혈 53명 총 127명으로 하였다. 대조군은 환자군과 비슷한 시기에 입원하는 경상대학교 병원의 신경과 이외 병동의 입원 환자중 환자군과 성(性)이 같고 연령이 5세 이내인 대상자를 환자군과 1:1 개별 짝짓기(individual matching)하여 127명을 선정하였다. 대조군은 과거에 뇌혈관질환의 병력이 없고 원칙적으로 뇌혈관질환의 잠재적 위험요인과 관계없는 질병으로 입원한 경우로만 하였다. 본 연구결과 논란이 있는 코골음과 저콜레스테롤혈증이 뇌혈관질환의 위험요인이라고 할 수 없었다. 유의한 위험요인은 심전도의 이상(좌심실비대 및 심방세동)이 가장 중요하였고, 그 외에도 뇌혈관질환의 가족력, 안저검사의 이상소견, 과거 일과성 허혈성 발작의 경험 및 혈청 콜레스테롤치의 상승이었다. 뇌경색의 위험요인은 역시 심전도의 이상이 가장 중요하였고, 그외에도 안저검사의 이상소견, 흡연 및 혈청 콜레스테롤치의 상승이었다. 이상의 위험요인을 고려할 때 뇌혈관질환을 예방하기 위해서는 고혈압의 치료가 중요하며, 특히 안저검사와 심전도 검사에서 이상소견이 나타나지 않도록 철저히 관리해야 한다. 가족력이 있는 사람들과 과거 일과성 허혈성 발작 경험자는 특히 고위험군으로서 다른 위험요인을 가지지 않도록 교육해야 한다. 또한 흡연과 고콜레스테롤 혈증의 건강에 대한 위해성도 다시 한번 강조되어야 한다. 이렇게 함으로써 보건당국은 단일 사망원인으로 우리나라에서 제1의 사망원인인 뇌혈관질환을 예방하기 위하여 더욱 노력해야 할 것이다.

Objective: This study evaluates the effectiveness and safety of moxibustion for benign prostatic hyperplasia (BPH). Methods: Using the keywords "benign prostatic hyperplasia", "benign prostatic hypertrophy", "benign prostatic enlargement", "prostatic hyperplasia", and "moxibustion", we searched papers in numerous databases, including National Discovery for Science Leaders (NDSL), Korean Traditional Knowledge Portal (KTKP), Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), PubMed, Embase, and CENTRAL. The search range included randomized controlled trials (RCTs). Papers not matched with inclusion criteria were excluded. The methodological quality of each RCT was assessed using the Cochrane risk-of-bias tool. Where appropriate, meta-analyses were performed. Results: Initially, 77 studies were found. Of these, 11 duplicate studies were removed and 27 were excluded following title and abstract screening. After the remaining 39 papers were scanned, 13 RCTs were selected and analyzed. Among these 13 RCTs, five compared moxibustion therapy and oral medication, seven compared moxibustion plus acupuncture therapy and oral medication, and one compared moxibustion plus acupuncture therapy and sham-moxibustion. The meta-analysis showed positive results for the use of moxibustion therapy in terms of International Prostate Symptom Score (IPSS), Quality Of Life (QOL), Maximum Flow Rate (Qmax), Prostate Volume (PV), and the efficacy rate. The meta-analysis showed positive results for the use of moxibustion plus acupuncture therapy in terms of IPSS, QOL, and the efficacy rate. Conclusions: This meta-analysis of clinical trials suggests that moxibustion is effective intreating BPH patients. The results of this study could be applied to clinical treatment of BPH. However, additional large-scale clinical researches should be conducted.

With the ligation of patent ductus arteriosus by Gross in 1938, surgeons first entered the field of congenital heart disease. Interruption of a ductus is one of the most satisfactory and curative operations in the field of surgery for congenital heart disease. 27 cases of isolated patent ductus arteriosus were operated from Jan. 1978 to July 1984 at the Department of Thoracic & Cardiovascular Surgery in Kyung-Hee University Hospital. Retrospective clinical analysis of these patients were: 1. Sex ratio, female: male, was 2:1. 2. Mean age at operation was 9.85\ulcorner.58 years. The youngest patient was a 23 month-old girl and the oldest one was a 24 year-old male. 3. More than half of the patients had less than 50 percentile of growth retardation. 4. Chief complaints of the patients were frequent URI [52%], dyspnea on exertion [33%], generalized weakness [22%], palpitation [7%], but 7 patients [26%] had no subjective symptoms. 5. Continuous machinery murmur could be heard at the 2nd or 3rd intercostal space on the left sternal border in 22 patients [81%]. The other S patients made systolic murmur with accentuation of the second heart sound and those were associated with pulmonary hypertension. 6. Radiologic findings of Chest P-A were cardiac enlargement in 15 patients [55%], enlargement of pulmonary conus and/or increasing density of pulmonary vascularity in 20 patients [74%]. 7. Electrocardiographic findings of the patients were within normal limit in 13 patients [48%], LVH in 4 patients [15%], biventricular hypertrophy in 3 patients [11%]. 8; echocardiogram was obtained from 11 patients. Ductus was directly visualized in 7 patients. Left atrial enlargement is the secondary change of left to right shunt, 10 patients had LA/Ao ratio more than 1.2. 9. Cardiac catheterization performed in 25 patients. The mean value of the results were:SO2[PA-RV]= 14.72\ulcorner6.01%, Qp/Qs=2.22\ulcorner.80, peak systolic pulmonary arterial pressure=48.28\ulcorner1.60 mmHg. 10. 26 patients were operated through the left posterolateral thoracotomy: closure of ductus by double ligation in 14 cases, triple ligation in 5 cases, and division with suture in 8 cases. One patient suffer from aneurysmal rupture of main pulmonary artery, endocarditis, hemopericardium was treated with cardiopulmonary bypass via median sternotomy and closure of ductus through the ruptured main pulmonary artery. 11.There was no death associated with the operation, but 3 cases were experienced with intraoperative rupture around the ductus resulting in massive bleeding. The other complications were transient hoarseness in one patient, atelectasis in left lower lobe in 3 patients, and postoperative systemic hypertension in 4 patients with unknown etiology. 12. Pulse pressure was reduced, 11.47+5.92 mmHg, postoperatively, as compare to preoperative status. 13. Intraoperative wedge lung biopsy from lingular segment for the evaluation of the pulmonary vascular disease was taken in S patients with severe pulmonary hypertension. The result was Heath-Edward grade I in one case, grade II in two cases, and grade III in two cases.

This study was conducted to investigate the effects of unilateral ovariectomy on the weight of the remaining ovary, the change of number of ovarian follicle, number of corpus luteum and serum progesterone level. Sixty Sprague-Dawley female rats, 23$\pm$2 days old, were divided into 2 groups (control and unilaterally ovariectomized goup) with 30 heads per groups. Each group was again subdivided into 6 groups according to 6 experimental periods; Day 4, 8, 12, 16, 20 and 24 after uniteral ovariectomy. Five arts at every 4 day intervals were sacrificed for the measuring of ovarian weight and for quantitative histologic examination of ovary and at the same time, blood samples were taken for the determination of serum progesterone level of radioimmunoassy. The results obtained were as follows: During the experimental periods, a significant hypertrophy occured in the remaining ovary of unilaterally ovariectomized group from day 16 after operation. The average ovarian weight of control group at day 16 was 21.0$\pm$1.7mg, which is samller than that of unilaterally ovariectomized group weighing 50.5$\pm$8.4mg(P<0.01). The ovarian weight of the unilaterally ovariectomized rats at day 20 and day 24 was 75.9$\pm$2.2 mg and 63.3$\pm$7.0 mg, which is heavier than those of control group; 29.1$\pm$2.3 and 26.3$\pm$1.7 mg(P<0.01 and P<0.01). 2. A same degree of ovarian follicle development was observed in the unilaterally ovariectomized group. Following unilateral ovariectomy and there was no change in total number of follicles larger than 130$\mu$ during the period from day 4 till day 24 after operation. 3. Although the size fo ovarian follicle did not significantly change between two groups from day 4 till day 16, the size of vesicular follicle in unilaterally ovariectomized group (406.3$\pm$26.2$\mu$) was significantly greater as compared to that of control group (323.8$\pm$19.3$\mu$)(P<0.05). 4. Corpus luteum in unilaterally ovariectomized and control group began to a, pp.ar from day 16 after operation and then the number of corpus luteum slightly increased. The number of corpus luteum in unilaterally ovariectomized group at day 24 ws remarkably increased (13.7$\pm$1.41) than that of control (5.2$\pm$2.01)(P<0.01). 5. Serum progesterone levels in unilaterally ovariectomized group were slightly higher than those of control but there were no significant difference between treatment groups.

간 섬유화에서 fat-storing cell의 변화를 미세 구조학적 측면에서 관찰하고자, 사염화탄소를 mineral oil에 녹여 1 : 1로 회석한 후 Kg당 0.5 ml의 용량을 주 2회씩 12주간 흰쥐에 복강 주입하였다. 실험기간 동안 1주 간격으로 도살하고, 적출된 간조직을 광학현미경과 연역조직화학적 검사 및 전자현미경으로 관찰하여 다음과 같은 결과를 얻었다. 광학현미경적 소견상 소엽 중심주의 염증 반응 및 세포 침윤 현상은 사염화탄소 투여 후 1주부터 나타나서 4주 째 가장 심하였으며, 이시기에 desmin염색 반응 양성세포의 수도 증가되었다. 괴사 및 섬유화는 2주부터 나타나기 시작하여 6주부터 결절이 형성되기 시작하였고 괴사성 병변은 8주까지 지속되었다. 그러나 세포 침윤 정도는 감소되면서 desmin에 대한 반응성도 낮아졌고, 경변성 변화는 10주 이후부터 나타났다. 전자현미경적 소견상 fat-storing cell의 숫적 증가는 1주부터 관찰되었으며 지방적이 감소하고 rER이 팽창된 이행세포는 2주째 출현하여 4주에 가장 현저히 증가되었다. 섬유아세포는 3주부터 나타나기 시작하였는데, rER이 확장되었으며 지방적은 없거나 1-2개의 소적이 세포돌기에서 관찰되었다. 섬유화가 진행됨에 따라 이행세포 및 fat-storing cell은 감소하고 섬유아세포는 증가된 상태를 유지하였다. 이상의 결과로 보아 fat-storing cell은 간섬유화 과정에서 활성화되고 증식하여 형태학적으로 이행세포 및 섬유아세포로 전환함으로써, 정지상태에 있는 섬유아세포의 전구체로서 간섬유화에 중요한 역할을 하는 것으로 사료된다.

BACKGROUND: Groundwater is believed to possess many beneficial effects due to its natural source of various minerals. In this study, we examined the effects of natural Jeju groundwater S1 (Samdasoo$^{TM}$), S2 and S3 pumped up from different locations of Jeju Island, Korea, along with local tap water, on body weight gain, serum lipids and lipoproteins, and liver histopathology in high-fat diet-induced hyperlipidemic rats. MATERIALS/METHODS: Rats were randomly and equally divided into 6 groups. Different water samples were supplied to the hyperlipidemic rats as their daily drinking water and the widely-used anti-hyperlipidemic drug simvastatin was used as a positive control. Body weight, serum lipids and lipoproteins were measured weekly. Liver weight, liver index and liver histopathology were examined after the execution of the rats. RESULTS: After drinking Jeju groundwaters for two months, S2 but not S3 significantly reduced weight growth and serum triglycerides levels and increased high density lipoprotein-C (HDL-C) without affecting total cholesterol or LDL-C. S1 and particularly S2 significantly reduced the severity of liver hypertrophy and steatosis. All Groundwaters had much higher contents of vanadium (S3>S2>S1>>tap water) whereas S1 and S2 but not S3 markedly blocked autoxidation of ferrous ions. CONCLUSION: Jeju Groundwater S1 and particularly S2 exhibit protective effects against hyperlipidemia and fatty liver and hypothesize that the beneficial effect of Jeju Groundwaters may be contributed from blockade of autoxidation of ferrous ions rather than their high contents of vanadium.

Objective: Hemicastration is a unilateral orchiectomy to remove an injured testis, which can induce hormonal changes and compensatory hypertrophy of the remaining testis, and may influence spermatogenesis. However, the underlying molecular mechanisms are poorly understood. Here, we investigated the impact of hemicastration on remaining testicular function. Methods: Prepubertal mice (age 24 days) were hemicastrated, and their growth was monitored until they reached physical maturity (age 72 days). Subsequently, we determined testis DNA methylation patterns using reduced representation bisulfite sequencing of normal and hemicastrated mice. Moreover, we profiled the testicular gene expression patterns by RNA sequencing (RNA-seq) to examine whether methylation changes affected gene expression in hemicastrated mice. Results: Hemicastration did not significantly affect growth or testosterone (p>0.05) compared with control. The genome-wide DNA methylation pattern of remaining testis suggested that substantial genes harbored differentially methylated regions (1,139) in gene bodies, which were enriched in process of protein binding and cell adhesion. Moreover, RNA-seq results indicated that 46 differentially expressed genes (DEGs) involved in meiotic cell cycle, synaptonemal complex assembly and spermatogenesis were upregulated in the hemicastration group, while 197 DEGs were downregulated, which were related to arachidonic acid metabolism. Integrative analysis revealed that proteasome 26S subunit ATPase 3 interacting protein gene, which encodes a protein crucial for homologous recombination in spermatocytes, exhibited promoter hypomethylation and higher expression level in hemicastrated mice. Conclusion: Global profiling of DNA methylation and gene expression demonstrated that hemicastration-induced compensatory response maintained normal growth and testicular morphological structure in mice.

BACKGROUND/OBJECTIVES: Benign prostatic hypertrophy (BPH) is a major cause of abnormal overgrowth of the prostate mainly in the elderly. Corni Fructus has been reported to be effective in the prevention and treatment of various diseases because of its strong antioxidant effect, but its efficacy against BPH is not yet known. This study was designed to evaluate the therapeutic efficacy of Corni Fructus water extract (CF) in testosterone-induced BPH rats. MATERIALS/METHODS: To induce BPH, rats were intraperitoneal injected with testosterone propionate (TP). Rats in the treatment group were orally administered with CF with TP injection, and finasteride, which is a selective inhibitor of $5{\alpha}$-reductase type 2, was used as a positive control. RESULTS: Our results showed that the increased prostate weight and histopathological changes in BPH model rats were suppressed by CF treatment. CF, similar to the finasteride-treated group, decreased the levels of testosterone and dihydrotestosterone by TP treatment in the serum, and it also reduced $5{\alpha}$-reductase expression and concentration in prostate tissue and serum, respectively. In addition, CF significantly blocked the expression of the androgen receptor (AR), AR co-activators, and proliferating cell nuclear antigen in BPH rats, and this blocking was associated with a decrease in prostate-specific antigen levels in serum and prostate tissue. CONCLUSIONS: These results suggest that CF may weaken the BPH status through the inactivation of at least $5{\alpha}$-reductase and AR activity and may be useful for the clinical treatment of BPH.
