Pheochromocytoma is a hazardous and dramatic cause of hypertension. This potentially lethal neoplasm originates in most cases in the adrenal medulla and less frequently in the cells of the extraadrenal paraganglion system which are disseminated along the paravertebral axis from the pelvis to the base of the skull. The organ of Zuckerkandl is paraganglia lying the abdominal aorta with highest incidence in the region of the inferior mesenteric artery and usually degenerate shortly after birth. In the literature, and additional one case of pheochromocytoma arising from the organ of Zuckerkandl associated with intracerebral hemorrhage which was treated recently in the Kyung Hee University Hospital is presented in this report.

For many years, interest in cardiac function has primarily centered around the systolic pump performance of the left ventricle. it is now recognized, however, that diastolic abnormalities may be just as important in the pathophysiology of certain cardiac disease states. To examine the left ventricular abnormalities (especially diastolic events) in hypertension, diastolic and systolic time intervals were measured from simultaneous high-speed recordings of a phonocardiogram, ECGs, apexcardiogram, echocardiogram and external carotid pulse in 35 hypertensive patients and were compared with those in 15 normal subjects. The hypertensive patients showed significantly prolonged preejection period (PEP) and shortened ejection time (ET), compared to those in normal control subjects (p<0.005, p<0.05 respectively). The PEP/ET ratio too was different from the control subjects in hypertensive patients (0.335+/-0.050 vs 0.422+/-0.666; p<0.005). The isovolumic relaxation time (IVRT) was increased to 81.3+/-15.0 msec, which was significantly longer (p<0.005) than in normal subjects (56.7+/-10.7 msec), in patients with hypertension. The active filling period (AFP) was also prolonged. In patients with hypertension there was no significant difference in rapid filling period and slow filling period compared with those in normal subjects. It is likely that in hypertensive patients the alterations of diastolic time intervals, reflecting disorders in elasticity and compliance, may occur in conjunction with abnormal systolic events.

During 1 year and 9 month period, from September, 1980 to June, 1983, retrospective study was performed on 35 patients with Mitral Valve Prolapse at Kyung Hee University Medical Center. And the following results were obtained; 1) The mitral valve prolapse syndrome presents with various cardiovascular symptoms including dyspnea(63%), palpitation(49%), chest pain(34%), syncope and dizziness(11%). 2) Of 35 patients with MVP, 17 cases were isolated MVP, 13 cases were associated with cardiovascular disorders and 5 cases were associated with non-cardiovascular disorders. 3) Electrocardiographic abnormalities were found in 20 patients with MVP. The most common abnormality was ST-T change and atrial fibrillation, VPB, RBBB, first degree A-V block and W-P-W syndrome were also noted. 4) QTc interval prolongation was more common in serverely symptomatic patients with MVP. 5) 18 cases in 35 patients showed systolic click or murmur on phonocardiography. 6) Of 35 patients with MVP, 19 patients demonstrated prolapse of the anterior leaflet, 11 patients demonstrated prolapse of posterior leaflet and 5 patients demonstrated prolapse of the both leaflets. 7) There were severe derangement on echocardiography in severely symptomatic patients were MVP.

We report here on an unusual case of mucinous cystic tumor that was associated with endometriosis in the cecum. A 45-year-old woman was admitted to the hospital due to her 5 day history of right lower quadrant abdominal pain with a mild fever. A laparotomy was performed under the clinical impression of the tubo-ovarian abscess. A relatively well defined a multi-locular cystic mass (8.0x8.0x7.0 cm) filled with white-to-yellow thick mucoid material was found in the wall of the cecum. The right ovary and fallopian tube showed marked fibrous adhesion to the external surface of the cecal mass. A right hemicolectomy and salpingo-oophorectomy were performed. Histologically, the tumor was similar to those of ovarian borderline mucinous tumor, the intestinal type, and the mucinous epithelium of the tumor was merged with the endometriotic epithelium and stroma. On immunostaining, the CK20 positive mucinous epithelium was well demarcated from the CK7 endometriotic epithelium. This is the first case of low-grade mucinous cystic tumor intimately associated with intestinal endometriosis in the cecum.

OBJECTIVE: Human papillomavirus (HPV) has been identified in the majority of invasive cervical cancer patient and has been found to contribute in a significant way to the genesis of human cervical cancer. HPV has two transforming genes that encode the oncoproteins E6 and E7, E6 can form complexes with p53 and promote p53 degradation, E7 inhibit retinoblastoma protein (RB). The p53 protein is as a phosphoprotein which co-immunoprecipitated with the SV40 T-Antigen. The wild type p53 protein is capable of suppressing the tumorigenic phenotype and regulating cell cycle. Adeno-associated virus(AAV) is a linear single stranded DNA parvovirus which is dependent upon cotransfection by a second unrelated virus to undergo productive infection. It has been well documented that AAV DNA integrates into cellular DNA as one to several tandem copies joined to cellular DNA through the termini. In order to introduce wild type p53 through AAV virus into a cervical cancer patient for gene therapy, we had constructed recombinant p53 adeno associated virus plasmid (pAAVCMVp53). METHODS: pAAVCMVp53 was created new AAV-vector system, pRc/CMVp53 including p53 cDNA and AAV-derivative vector, pASPA-AAV-CMV-polyA were made to HindIII/blunt fragments. Eluated 1.8 kb fragment of wild type p53 cDNA was ligated to pAAV-CMV-polyA, 4.9 kb fragment deprived hASPA cDNA. RESULT: Recombinant AAVCMVp53 was constructed by using pRc/CMVp53 andpASPA-AAV-CMV-polyA. This pAAVCMVp53 was confirmed by various restriction enzyme-digestions and Southern-blotting. This new vector system will be studied on expression, stability in cervical cancer cell lines and animals. CONCLUSION: This system will be one of the useful vector system for cervical cancer gene therapy.

OBJECTIVE: The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. METHOD: This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points: at baseline, and 1,2,4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. RESULTS: 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action: a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. CONCLUSIONS: This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
