BACKGROUND: Thromboxane A2 and endothelin-1 are the potent vasoconstrictors affecting pulmonary pathophysiology in response to whole body inflammatin following CPB. Aprotinin, as an antiiflammatory agent, may decrease the release of such vasoactive substance from pulmonary tissues, preventing pulmonary hypertension after cardiopulmonary bypass. MATERIAL AND METHOD: Ten mongrel dogs(Bwt. ac. 20kg) were subjected to cardioupulmonary bypass for 2 hours and postbypass pulmonary vascular resistance(0, 1, 2, 3 hours) were compared with prebypass level. The dogs were divided into 2 groups; control group(n-5) and aprotinin group(n=5). In the aprotinin group, aprotinin was administered as follows; 50,000 KIU/kg mixed in pump priming solution, 50,000 KIU/kg prebypass intravenous infusion over 30 minutes, 10,000 KIU/kg/hour postbypass continuous infusion. Prebypass and postbypass 0, 1, 2, 3 hour pulmonary vascular resistance were measured. At prebypass and postbypass 0, 90, 180 minutes, blood samples were obtained from pulmonary arterial and left atrial catherers for the assay of plasma thromboxane B2 a stable metabolite of thromboxane A2, and endothelin-1 concentrations. RESULT: The ratios of pustbypass over prebypass pulmonary vascular at postbypass 0, 1, 2, 3 hours were 1.28+/-0.20, 1.82+/-0.23, 1.90+/-0.19, 2.14+/-0.18 in control group, 1.58+/-0.18, 1.73+/-0.01, 1.66+/-0.10, 1.50+/-0.08 in aprotinin group ; the ratios gradually increased in control group while decreased or fluctuated after postbypass 1 hour in aprotinin group. There was statistically significant difference between control group and aprotinin group at postbypass 3 hours(P=0.014). Pulmonary arterial plasma concentration of thromboxane B2(pg/ml) at prebypass, postbypass 0, 90, 180 minutes were 346.4+/-61.9, 529.3+/-197.6, 578.3+/-255.8, 493.3+/-171.3 in control group, 323.8+/-118.0, 422.6+/-75.6, 412.3+/-59.9, 394.5+/-154.0 in aprotinin group. Left atrial concentrations were 339.3+/-89.2, 667.0+/-65.7, 731.2+/-192.7, 607.5+/-165.9 in control group, 330.0+/-111.2, 468.4+/-190.3, 425.4+/-193.6, 4.7.3+/-142.8 in aprotinin group. These results showed decrement of pulmonary thromboxane A2 generation in aprotinin group. Pulmonary arterial concentrations of endothelin-1(fmol/ml) at the same time sequence were 7.84+/-0.31, 13.2+/-0.51, 15.0+/-1.22, 16.3+/-1.73 in control group, 7.76+/-0.12, 15.3+/-0.71, 22.6+/-6.62, 14.9+/-1.11 in aprotinin group. Left atrial concentrations were 7.61+/-17.2, 57.1+/-28.4, 18.9+/-18.2, 31.5+/-20.5 in control group, 5.61+/-7.61, 37.0+/-26.2, 28.6+/-21.7, 37.8+/-30.6 in aprotinin group. These results showed that aprotinin had no effect on plasma endothelin-1 concentration after cardiopulmonary bypass. CONCLUSIONS: Administration of aprotinin during cardiopulmonary bypass could attenuate the increase in pulmonary vascular resistance after bypass. Inhibition of pulmonary thromboxane A2 generation was thought to be one of the mechanism of this effect. Aprotinin had no effect on postbypass endothelin-1 concentration.

Since Folkman's novel hypothesis, it is well known that tumors depend on the angiogenesis for their growth, expansion, and possibly metastasis. Several angiogenic factors have been identified and shown to be produced by tumors. In some cancers, the angoigenic activity in the tumor is correlated with the clinical outcome. Clinically, the presence of macroscopic or colposcopic abnormal vascular patterns of the uterine cervical lesions would suggest that the angiogenic activities are associated with various cervical squamous epithelial lesions. This study was designed to look at the relationship between angiogenesis and squamous epithelial lesions of the uterine cervix and to determine whether squamous intraepithelial lesions are angiogenic as cervical cancers are. Tissue sections from 53 surgical specimens(6 normal cervix, 4 chronic cervictis, 9 low grade SII, 8 high grade SIL, 7 MIC, 19 squamous cell carcinoma) were immunohistochemically stained for CD 34 a specific marker for endothelial cels. Stained vessels in the most intense area on a X200 light microscopic field were selected and counted automatically using computer software for color-image analysis. Stained vessel counts were 19.7 +/- 9.1 in normal cervix, 33.5 +/-5.8 in chronic cervicitis, 38.8 +/- 10.9 in LGSIL, 67.0 +/- 23.6 in HGSIL, and 73.4 +/- 20.6 in microinvasive carcinoma, 77.8 +/- 28.7 in squamous cell carcinoma, respectively. Vessel counts showed a statistically increasing tendency in more advanced squamous epithelial lesins. Tumor angiogenesis is not related to inflammatory response. Also, the process of the angiogenic switching may begin from low grade SIL to high grade SIL. This study suggests that the angiogenic activity also involved in SILs as invasive cancer are and may be related to grade of SELs.

BACKGROUND: Persistent facial telangiectasia, erythema and flushing are the major cosmetic problems in patients with rosacea. However various therapeutic treatments for rosacea papules and pustules are not effective in reducing telangiectasia and flushing reactions. Matrix-centered theory that dermal matrix degradation can cause telangiectasis, erythema and flushing, is one of the various theories of rosacea pathogenesis. Shark cartilage extracts are collagenase inhibitors and can inhibit dermal matrix degradation. OBJECTIVE: The purpose of this study was to evaluate the clinical effects of shark catilage extracts (Venatrix(R)) for erythematotelangiectatic rosacea patients. METHODS: Twenty three patients with erythematotelangiectatic rosacea applied shark cartilage extracts twice daily for up to 8 weeks. Efficacy was evaluated by erythema index using mexameter (MPA 5, CK, Germany) and clinical photography. RESULTS: Erythema index decreased from 525.7+/-114 to 413.9+/-101.7 (mean reduction: 21.3%) (p<0.1) after 8 weeks treatment. 16 patients (69%) showed excellent or good results by clinical photography. Transient stinging sensation was the most common adverse effect and these symptoms improved after the first few days. There were no other significant side effects. CONCLUSION: Shark cartilage extracts may be an effective treatment for mild erythematotelangiectatic rosacea.

BACKGROUND: The study investigated in detail the current status of the consultations requested in a pain clinic. We evaluated the characteristics of the consultations to determine the kind of contents requested, referring departments and factors including demographics, co-morbidities, previous medical problems, and the descriptions of the reasons for the consultation to the pain clinic. METHODS: Clinical data were collected in the authors' institution between 1 January 2009 and 31 December 2013. The medical records were reviewed and compared. Characteristics of both outpatients and inpatients were analysed. RESULTS: Data from 1,140 patients was available for this study. Seven hundred thirteen individuals belonged to the outpatient group and 427 individuals belonged to the inpatient group. Orthopedic surgery, neurosurgery, and otolaryngology were the main departments that requested consultations to the pain clinic. The most frequent requested lesion and diagnostic term were low back and lumbar spinal stenosis, respectively, and the most common reason for consulting was for "control of pain not controlled by medications." Factors that were significantly different between the two groups were gender, questions about other illnesses apart from the main diagnoses, history of specific diseases, acute onset, cancer, operation within 3 months, and physical system abnormalities. CONCLUSIONS: The medical problems addressed by a pain clinic consultation service were diverse. It is rational to develop standardized guidelines for pain consultations, and treatment strategies aimed at alleviating pain per se as well as caring for comorbid conditions.

BACKGROUND/AIMS: JX-594 is an oncolytic virus derived from the Wyeth vaccinia strain that causes replication-dependent cytolysis and antitumor immunity. Starting with a cross-examination of clinical-trial samples from advanced hepatocellular carcinoma patients having high levels of aldosterone and virus amplification in JX-594 treatment, we investigated the association between virus amplification and aldosterone in human cancer cell lines. METHODS: Cell proliferation was determined by a cell-counting-kit-based colorimetric assay, and vaccinia virus quantitation was performed by quantitative polymerase chain reaction (qPCR) and a viral plaque assay. Also, the intracellular pH was measured using a pH-sensitive dye. RESULTS: Simultaneous treatment with JX-594 and aldosterone significantly increased viral replication in A2780, PC-3, and HepG2 cell lines, but not in U2OS cell lines. Furthermore, the aldosterone treatment time altered the JX-594 replication according to the cell line. The JX-594 replication peaked after 48 and 24 hours of treatment in PC-3 and HepG2 cells, respectively. qPCR showed that JX-594 entry across the plasma membrane was increased, however, the changes are not significant by the treatment. This was inhibited by treatment with spironolactone (an aldosterone-receptor inhibitor). JX-594 entry was significantly decreased by treatment with EIPA [5-(N-ethyl-N-isopropyl)amiloride; a Na+/H+-exchange inhibitor], but aldosterone significantly restored JX-594 entry even in the presence of EIPA. Intracellular alkalization was observed after aldosterone treatment but was acidified by EIPA treatment. CONCLUSIONS: Aldosterone stimulates JX-594 amplification via increased virus entry by affecting the H+ gradient.

BACKGROUND: Laparoscopic procedures and ultrasonography are now commonly used in the obstetric field, and more non-obstetric procedures are being performed. However, little domestic data has been published on the topic. This present retrospective study investigated the clinical information and the effect on perinatal outcomes of non-obstetric surgery during pregnancy. METHODS: This retrospective study was performed using data of all adult pregnant women that underwent non-obstetric surgery at our institute between from July 2009 to December 2016. Data was collected from the institutional computerized database. The causes, types, and the gestational ages at surgery were collected as our primary outcomes. Basic characteristics of patients, operation times, anesthesia times, anesthetic methods, anesthetic agents, and adverse perinatal outcomes such as abortion or preterm delivery were evaluated as secondary outcomes. RESULTS: During the study period, there were 2,421 deliveries and 60 cases of non-obstetric surgery, an operation rate of 2.48%. The most common cause of non-obstetric surgery was abdominal surgery, followed by orthopedic surgery and neurosurgery. Most of abdominal surgeries were performed laparoscopically during the first trimester. The incidence of adverse perinatal outcomes was increased in the first trimester, was not related with anesthesia. CONCLUSIONS: The rate of non-obstetric surgery was found to be 2.48%, which was higher than those reported in previous domestic studies. This increase seems to have resulted from early diagnosis by ultrasonography and non-invasive surgery using laparoscopy. Adverse perinatal outcomes are not related with age, surgery and anesthetic-related factors but seem to be associated with surgery exposure stage, especially the first trimester.

OBJECTIVES: The purpose of this study was to evaluate the long-term efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. METHOD: This multicenter open label study included 116 schizophrenic patients drawn from 19 university hospitals. After a wash-out period of 1 week, the patients were treated with risperidone for 56 weeks and evaluated at 8 points:at baseline, and the 8th, 16th, 24th, 32nd, 40th, 48th, 56th weeks of treatment. The dose was started at 2mg of risperidone on day 1, and increased to 4mg on day 2, and 6mg on day 3,7 and adjusted to a maximum of 16mg/day according to the individual's clinical response. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. RESULTS: Eighty-seven(75%) of 116 patients completed the 56-week trial of risperidone. Clinical improvement(as defined by a 20% of reduction in total PANSS score at end point) was shown by 92.0% of the patients. The mean dose of risperidone was 5.0mg/day in the 56 week follow-up. PANSS total scores showed significant improvements between consecutive two points at baseline, 8th, 16th, 24th, 32nd, and 48th week of treatment. CGI scores showed significant reductions between consecutive two points at baseline, 8th, 16th, 24th, and 48th week of treatment. Three PANSS factors(positive, negative, general) showed a significant improvement from the 8th week of treatment, and, after then, remained improved in the rest of the study period. ESRS showed no significant change during the 56 week trial. Laboratory parameters showed no significant changes during the course of treatment. CONCLUSIONS: This multicenter long-term open study suggests that risperidone is a antipsychotic drug with long term efficacy and safety in the treatment of schizophrenic patients.
