BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

PURPOSE: While the exact inflammatory and immunological mechanisms involved in the induction of immunotherapy for superficial bladder carcinoma are mostly unknown, many of these mechanisms are mediated through the activation of transcription factors involved in signal transduction pathways Nuclear Factor Kappa B(NFkappaB) signal transduction pathways induce transcription factors that activate genes encoding immunological proteins such as cytokines and cell Surface maskers. This study investigates the activation pattern of NFkappaB by lipopolysaccharide(LPS), interferon gamma(INFgamma), and tissue necrosis factor alpha(TNFalpha) in low(RT4) and high(T24) grade transitional carcinoma cell lines. MATERIALS AND METHODS: Low and high grade transitional carcinoma cell lines were cultured with Eagle's minimum essential medium. Using electrophoretic mobility shift assays(EMSA) of whole cell extracts from cell cultures of RT4 and T24 after exposure to LPS, INFgamma and TNFalpha, activation of NFkappaB complex has been demonstrated. Degradation of IkappaB has been demonstrated by Western blot analysis using IkappaBalpha /MAD-3. RESULTS: NFkappaB complex was induced by TNFalpha in both RT4 and T24 cells as determined by EMSA. NFalphaB complex was also Induced by INFgamma in the RT4 cells but not in the T24 cells. However in LPS treatment, the NFkappaB complex was strongly induced in T24 cells and the induction was very weak in RT4 cells. Inhibitor of NFkappaB (IkappaBalpha) was degraded rapidly after LPS treatment in the T24 cells as determined by Western blot analysis with IkappaBalpha specific antibody. However, the level of IkappaBalpha protein was same in the RT4 cells before and after LPS treatment. CONCLUSIONS: Identification of differences in low and high grade tumor cell lines in the inducibility of transcription factors by LPS and INFgamma provide an opportunity for understanding the observed differences in the mechanisms within the signal transduction pathways will ultimately create disease specific as well as patient specific treatments for these malignant urothelial disorders.

To histologically compare benign prostatic hyperplasia with proslalic adenocarcinoma, a morphometric study was conducted on 20 cases of benign prostatic hyperplasia and 16 cases of prostatic adenocarcinoma. Adenocarcinoma group was divided into two subgroups. well differentiated (9 cases) and poorly differentiated (7 cases), based on the Gleason grading system. By means of computerized image analyzer, about 30 to 40 cells for each case were examined to evaluate mean nuclear area and perimeter, mean standard deviations and mean form factor. Mean form factor, the most prominent parameter in our study, was significantly different among BPH (1.063+/-0.008), well differentiated adenocarcinoma (1.089+/-0.018) and poorly differentiated adenocarcinoma (1.135 +/-0.057 ). Mean standard deviations of mean nuclear area and perimeter were significantly different between benign prostatic hyperplasia and well differentiated prostatic adenocarcinoma. .Morphometry. may provide the pathologists with a helpful technique, allowing them to analyze pathological material accurately. and in a more quantitative and reproducible fashion.

The purpose of this study was to investigate the influence of hypothermia on the recovery time after either vecuronium or atracurium given by repeated bolus injection, and to determine the adequate time of administration of neuromuscular blockers during cardiopulmonary bypass. Two groups of 10 patients each were studied before(Tl), during(T2) and after(T3) hypothermia. Following an initial intravenous bolus dose of 2X ED95 of either vecuronium(Group I) or atracurium(Group II), repeated bolus dose of ED95 was injected whenever twitch tension had returned to 20% block of train-of-four response before bypass of control As a result, the action duration of vecuronium(from injection of loading dose to twitch tension=20%) was 29.5+/-5.5 mins, 103.1+/-12.0 mins and 70.8+/-9.9 mins before, during and after hypothermia, respectively. The eorresponding values for atracurium were 26.3+/-5.1 mins, 85.7+/-11.4 mins and 42.5+/-5.1 mins. We conclude that hypothermia increases significantly the duration of action of both muscle relaxants(P<0.001) and vecuronium is influenced by hypothermia more than atracurium. The rate of recovery of twitch height after hypothermia is more rapid in atracurium than vecuronium(P<0.001). Single bolus injection of ED95 of vecuronium administered just before cardiopulmonary bypass is suitable for maintaining the neuromuscular block throughout cardiopulmonary bypass.

Double primary cancer is defined as the case of primary malignant tumors in one person, which must be arisen in different sites and have a different histologic appearances in each other. The number of reported cases of multiple primary malignant tumors has increased in recent years, because of more developed diagnostic procedure and long survival of cancer patients, We have experienced 4 cases of double primary malignant tumors which were stomach cancer with colon, bronchus and esophagus cancer, and report these cases with review of literatures.
