Abstract
A population of human T cells expressing an invariant V alpha 24 J alpha Q T cell antigen receptor (TCR) alpha chain and high levels of CD161 (NKR-P1A) appears to play an immunoregulatory role through production of both T helper (Th) type 1 and Th2 cytokines. Unlike other CD161(+) T cells, the major histocompatibility complex-like nonpolymorphic CD1d molecule is the target for the TCR expressed by these T cells (V alpha 24(invt) T cells) and by the homologous murine NK1 (NKR-P1C)+ T cell population. In this report, CD161 was shown to act as a specific costimulatory molecule for TCR-mediated proliferation and cytokine secretion by V alpha 24(invt) T cells. However, in contrast to results in the mouse, ligation of CD161 in the absence of TCR stimulation did not result in V alpha 24(invt) T cell activation, and costimulation through CD161 did not cause polarization of the cytokine secretion pattern. CD161 monoclonal antibodies specifically inhibited V alpha 24(invt) T cell proliferation and cytokine secretion in response to CD1d+ target cells, demonstrating a physiological accessory molecule function for CD161. However, CD1d-restricted target cell lysis by activated V alpha 24(invt) T cells, which involved a granule-mediated exocytotic mechanism, was CD161-independent. In further contrast to the mouse, the signaling pathway involved in V alpha 24(invt) T cell costimulation through CD161 did not appear to involve stable association with tyrosine kinase p56(Lck). These results demonstrate a role for CD161 as a novel costimulatory molecule for TCR-mediated recognition of CD1d by human V alpha 24(invt) T cells.

Abstract
UNLABELLED The aim of our study is to discuss our observations concerning surgical treatment of rare diseases of the oesophagus. 10 patients were operated on, 6 cases with benign tumours (including leiomyoma, Abrikossoff tumour, polyp of oesophageal mucose), 2 with intramural bronchogenic cysts of the oesophagus, 1 with benign stricture after inflammation and 1 with stricture of oesophagogastric anastomosis after Akiyama operation. In 6 cases tumour was resected without opening of the oesophageal lumen (enucleation), in 4 patients with tumours located on one of the walls, the wedge resection, transversely to the long oesophageal axis was performed. In cases with tumour located in mucose (Abrikossoff tumour, polyp, post-inflammatory scar), intraoperative fiber-esophagoscopy was conducted simultaneously to enable the exact localisation of tumour and evaluation of radical resection. There were no postoperative complications and dysphagia showed regression. The remote results (from 1 year to 6 years) have been found to be satisfactory. CONCLUSIONS 1. The procedure of choice in the treatment of the intramural cysts and benign tumour of the oesophagus is enucleation and wedge resection with suture in layers in the tumour located in mucose. 2. Intraoperative fiber-esophagoscopy enables the exact lesion localisation and evaluation of radical resection.

Abstract
The aim of the study is to discuss our observations concerning oesophagogastric bypass anastomosis in cases with scar stricture of cardia in long-term achalasia (megaoesophagus). The Heller operation is ineffective in such patients and the resection of cardia with oesophagogastric anastomosis is a large and controversial operation. 16 patients were operated (6 of them after ineffective cardiomyotomy). In all cases long-term dysphagia, big loss of weight and large, S-shaped oesophagus lying on the diaphragm were found. The left side thoracotomy was performed and fundus of the stomach was dislocated to the chest through dilatatored oesophageal hiatus and with the oesophagus above the cardia. There were no postoperative complications. However, dysphagia regressed. The remote results (from 1 year to 7 years) in 11 patients were analysed. The general condition was satisfactory. No dysphagia and gastrooesophageal reflux was revealed. Anastomosis was efficient in X-ray examination. Our observations indicate that oesophagogastric anastomosis is a procedure of choice in the treatment of long-term achalasia with stricture of cardia and megaoesophagus.

Abstract
UNLABELLED The x-ray examinations usually do not reveal morbid changes after lung expansion in the treatment of spontaneous pneumothorax. In our observation computed tomography (CT) and scintigraphy enable not only the exact determination of the extent of changes but also they disclose bullae invisible in conventional chest radiographs. 15 patients with cured spontaneous pneumothorax and 10 patients with radiographic evidence of a bulla or bullae were examined. CT scans showed bullae from 3 to 18 cm in diameter involving predominantly the upper lobes. 4 patients had additionally subpleural or intraparenchymal bullae of various degrees. In all patients with cured spontaneous pneumothorax, CT scans revealed intraparenchymal bullae, and in 6 cases bilateral intraparenchymal bullae were revealed. Only in sites of large bullae, no isotopic marker or its low elimination was shown in perfusion and inhalation scintigraphy. 10 patients with giant bullous emphysema were operated; in 6 patients enucleation of bullae, in 3 lobectomy and in one patient bullectomy were performed. CONCLUSION CT is a method of choice in the diagnosis of lung emphysematous bullae and it enables the detection of the changes undetectable in chest radiographs. Perfusion and inhalation scintigraphy is helpful in the diagnosis of large emphysematous bullae and postoperative follow-up examination.

Abstract
Serum tumor markers may be helpful in early diagnosis of cancer, in the initial assessment of the extent of the disease, and in monitoring the tumor growth or tumor volume reduction once cancer has been diagnosed and treatment started. Recent studies have focused on a new family of markers -hematopoietic growth factors, especially on granulocyte-macrophage colony-stimulating factor (GM-CSF). A number of investigations have shown autologous production of GM-CSF in various human cell lines derived from melanoma, gastric or ovarian cancer, and in certain tumors of nonhematopoietic origin. In this study serum level of GM-CSF was measured using a sensitive sandwich ELISA system in 34 patients with non-small cell lung cancer (NSCLC) before and 10, 30, 90, 180 and 270 days after surgical operation. Additionally common accepted tumor markers such as CEA and CYFRA 21.1 were also assayed. Preoperative level of GM-CSF was significantly increased in cancer patients relative to the normal sera (p < 0.02). Concentration of GM-CSF and CYFRA 21.1 were decreased on 10th day, but CEA on 30th day after surgical treatment, although upon comparison of pre- and postoperative tumor markers serum levels significant difference was observed for CYFRA 21.1 (p < 0.05). Levels of GM-CSF were increased in 85%, CEA in 62% and CYFRA 21.1 in 51%. The diagnostic sensitivity and serum levels of GM-CSF were related to the stage of the disease and the combined use of two markers increased the sensitivity compared with the use of only one. These results suggest that GM-CSF, especially in the combination with CYFRA 21.1., may be useful in the diagnostic and monitoring of patients with NSCLC.

Abstract
Activity and tissue localization of cathepsin G were examined in tumors deriving from 73 patients with non small cell lung cancer. Activity of cathepsin G was highest in adenocarcinoma, lower in planoepitheliale cancer, the lowest in macrocellular cancer. In all histological types of tumors cathepsin G activity in supernatants was lower than in sediments. The enzyme immunohistochemically was localized in neutrophils. There is evident correlation between neutrophil numbers and cathepsin G activity in examined cancer types. Result of our examinations indicate a relationship between cathepsin G activity, grade of tumor differentiation and particular clinical stages of disease.

Abstract
Cytokeratins (CK) are one of the main families of intermediate filaments which make up the cytoskeleton. CK19 is strongly expressed by normal simple bronchial and respiratory epithelium as well as by their malignant counterpart. Although CK19 is a part of the cytoskeleton, a soluble fragment of this polypeptide can be released and assayed in the blood as CYFRA 21-1, new sensitive and valuable marker of non small cell lung cancer. In some cases, however, discrepancies between the serum level of CYFRA 21-1 and presence of tumor and its histological type have been observed. We studied immunohistochemically tissue localization of CK19 in tumors and non invaded lung parenchyma in a series of 34 patients surgically treated due to lung cancer. CK 19 was detected in cancer cells as well as in non neoplastic epithelium covering bronchial tree and alveolar surfaces. We found a different expression of CK19 in different histological type of tumors. The most intensive expression revealed squamous cell carcinomas and adenocarcinomas. Small cell cancer revealed poor expression of CK19. In non invaded parts of the resected lungs we found the strong expression of CK19 in the cytoplasm of regenerative II type pneumocytes occurring in large quantity in the cases of interstitial lung fibrosis concomitant with some tumors. We suggest it may be a cause of unexpectedly elevated serum levels of CYFRA 19-21 in some not oncological patients or patients with small cell lung cancer.

Abstract
Activity and tissue localization of cathepsin D were examined in tumors deriving from 80 patients with non small cell lung cancer. Activity of the enzyme was higher in sediments and supernatants of tumors than in non invaded lung parenchyma. In all histological types of tumors cathepsin D activity in sediments was three times lower and in lung parenchyma five times lower than in supernatants. The immunohistochemical technique was used for enzyme localization. We observed seemingly the lack of correlation between activity of cathepsin D examined in tumors and immunohistochemical reaction intensity in neoplasm cells. Different numbers of macrophages and quantity of tumor stroma could explain this effect in examined histological types of cancer. Results of our explanations indicates for relations between cathepsin D activity versus histological type and degree of tumor differentiation. We did not observe correlation between cathepsin D activity versus lymph node metastases and clinical stages.

Abstract
A herd of 277 beef-breed calves in three age groups was mistakenly given the poultry coccidiostat maduramicin in a total mixed ration. It caused an acute toxicosis in which sudden death was the sole clinical finding in most cases. One group of 212 calves aged five to eight months suffered a mortality of 51 per cent in eight days and a total mortality of 56 per cent during the 40 days in which mortality was recorded. Mortality of only 3 per cent was recorded in two other groups of calves aged nine to 16 months in eight days and a total mortality of 11 per cent over the 40-day period.

Abstract
The CYFRA 21-1 assay is a test that has been developed recently for detection of a cytokeratin 19 fragment in serum. A diagnostic role for CYFRA 21-1 has already been proposed. The question of whether this marker is prognostically significant is important in clarifying the role of CYFRA 21-1 in clinical practice. The aim of this study was to evaluate the prognostic significance of elevated preoperative CYFRA 21-1 levels in patients with resected primary squamous-cell lung cancer (SqCC). Serum levels of CYFRA 21-1 were measured using an immunoradiometric assay (CIS bio) in 91 patients with operable SqCC. Survival and disease-free survival curves related to initial levels of this marker were estimated using the Kaplan-Meier method. In the univariate analysis the log-rank test and the log-rank test for trend were used. In the multivariate analysis the stratified log-rank test and the proportional hazard model were used. Elevated preoperative CYFRA 21-1 levels were identified in 55% of patients with SqCC. The number of patients with elevated levels of this marker increased with TNM stage (P = 0.0001). In univariate analysis elevated levels of CYFRA 21-1 were significantly associated with poor overall survival (P < 0.00005) and with disease-free survival (P < 0.00005). In multivariate analysis elevated levels of this marker were also found to be associated with poor overall and disease-free survival (P = 0.01 and P = 0.003 respectively). In conclusion, CYFRA 21-1 may be an independent prognostic parameter of survival and tumour relapse in SqCC and may be useful in identifying resected SqCC patients at high risk of treatment failure.

Abstract
Post-term pregnancy is associated with increased perinatal mortality. In a retrospective study based on our post-term protocol from 1990 until May 1995 1,798 post-term pregnant women with reliable dating were evaluated for expectant management. A group of 2,633 pregnant women who delivered between 37 and 41 weeks during 1994 served as a control group. The perinatal mortality (0.56 per 1,000 vs. 0.75 per 1,000 in the control group) was similar in both groups. The incidence of induction of labor (7.45% vs. 7% in the control group), meconium of more than +1 (5.2% vs. 4% in the control group), shoulder dystocia (0.33% vs. 0.19%), high birthweight (> 4,500 g) (1% vs. 1%), and cesarean section rates (7.5% vs. 7% in the control group) were similar. However the fetal distress rates (11.6% vs 16%; P = .004), instrumental deliveries (10.1% vs. 13%, P = .002), and the rate of 5-minute Apgar score of less then 7 (1.1% vs. 5%, P = .000001) were found to be significantly lower in the post-date group than in the control group. We conclude that the expectant management and our intensive observation and follow-up in post-term is indicated for both mother and fetus.

Abstract
OBJECTIVE The authors reviewed the results of endoscopic retrograde cholangiopancreatography (ERCP) and intraoperative cholangiography in a series of patients who underwent laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA The indications for preoperative and postoperative ERCP and intraoperative cholangiography as adjuncts to laparoscopic cholecystectomy are evolving. The debate regarding the use of selective or routine intraoperative cholangiography has intensified with the advent of laparoscopic cholecystectomy. METHODS The authors reviewed the records of 343 consecutive patients who underwent laparoscopic cholecystectomy during a 1-year period. Historical, biochemical, and radiologic findings for the patients who underwent ERCP and intraoperative cholangiography were analyzed. RESULTS Three hundred forty- three patients underwent laparoscopic cholecystectomy during the period reviewed. Preoperative ERCP was performed in 42 patients. Twenty-seven of these patients (64%) had common bile duct (CBD) stones, which were cleared with a sphincterotomy. Intraoperative cholangiography was performed for 101 patients (29%). Three cholangiograms had false- positive results (3%), leading to two CBD explorations, in which no CBD stones were found, and one normal ERCP. Six patients underwent postoperative ERCP, three for the removal of retained CBD stones (0.9%), all of which were cleared with a sphincterotomy. Fifteen patients had gallstone pancreatitis, six of whom had CBD stones (40%) that were cleared by ERCP. There were 33 complications (10%) and no CBD injuries. CONCLUSION The use of routine intraoperative cholangiography is discouraged in view of its low yield and the significant rate of false positive cholangiogram results.

Abstract
The aim of this study was to evaluate serial determinations of CYFRA 21-1 in the follow-up of patients treated surgically for non-small cell lung cancer in order to predict the risk of tumour recurrence. Serum levels of CYFRA 21-1 were measured using an immunoradiometric assay (CIS bio) in 57 patients with operable non-small cell lung cancer (NSCLC): 25 with squamous cell carcinoma (SqCC), 20 with adenocarcinoma (AC), 12 with large cell carcinoma (LCC) and 30 with non-malignant lung diseases. Elevated preoperative CYFRA 21-1 levels were identified in 44% of all patients with NSCLC. The diagnostic specificity of the assay was 97%. Positive CYFRA 21-1 levels was observed in 30% of stage I, 33% of stage II, and 55% of stage IIIa. Statistically significant differences were obtained between stages I and IIIa, II and IIIa, but not between stages I and II. During follow-up recurrence was observed in 19 of 57 (33%) NSCLC patients. Recurrence-free survival probability for patients with elevated serum CYFRA 21-1 levels before surgery was 52% (13/25), versus 81% (26/32) for patients with normal serum CYFRA 21-1 levels (p < 0.01). In 15 patients with increased trend for CYFRA 21-1, elevated serum CYFRA 21-1 levels preceded (13 patients) or coincided (2 patients) with the clinical detection of tumour recurrence, providing a predictive value of an increased trend of 87%. In the multivariate analysis the association of the increase of CYFRA 21-1 level with a higher risk of recurrence is statistically significant (p < 0.001).

Abstract
Within the past few years, the measurement of serum and tissue markers has had an increasing influence on clinical decisions about initial treatment and follow-up. Lung cancer illustrates the types and importance of these various markers. This review presents data concerning the most studied and interesting markers in non-small cell (NSCLC) and small cell lung cancer (SCLC). CEA, TPA, SCC-Ag, CYFRA 21-1, ferritin, CA19-9, CA50, CA242, H-K-N-ras mutations and p53 mutation seem to be the most prolific in NSCLC, while NSE, BN/GRP, CK-BB, NCAM, IL-2R, IGF-I, transferrin, ANP, mAb (cluster 5), Le-y and c-N-L-myc mutation are markers in SCLC patients. Some of these serum markers might be useful adjuncts for monitoring response to therapy, including early detection of tumour reactivation to allow curative therapy and rapid detection of treatment failure to allow change of the regimen. The study of these markers also may lead to a better understanding of the biological characteristics of lung cancer. The information derived from these biological studies represents the most promising avenue towards new treatment strategies, as well as attempts at secondary prevention.

Abstract
Despite extensive research, the role of the commonly employed tumour markers in the diagnosis of lung carcinoma is yet to be clarified. The utility of a new marker, CYFRA 21-1, in the preoperative evaluation of patients with bronchogenic carcinoma was investigated. CYFRA 21-1 was determined with a radiometric assay in serum of 280 patients with lung cancer and 208 patients with various nonmalignant lung diseases. The levels of the marker were significantly higher in lung cancer patients. Among benign lung diseases, elevated CYFRA 21-1 levels were found in pulmonary fibrosis. Using a cut-off of 3.2 ng.ml-1 (95th percentile of levels obtained in benign lung disease), the total sensitivity of the marker was 48%. The best sensitivity was obtained in squamous cell lung cancer (60%). The highest values of CYFRA 21-1 were found in metastatic lung cancer, and the marker sensitivity was more elevated in stage IIIb and IV. On the other hand, 40% of patients with surgically resectable lung cancer had CYFRA 21-1 levels above the cut-off. We conclude that CYFRA 21-1 may be satisfactorily employed in the differential diagnosis between malignant and benign lung diseases in association with other clinical and radiological data.

Abstract
We wanted to investigate the diagnostic and prognostic significance of serum CYFRA 21-1, especially in predicting the risk of recurrence in patients with operable squamous cell lung cancer. Serum levels of CYFRA 21-1 were measured using an immunoradiometric assay (CIS bio) in 76 patients with squamous cell lung cancer (64 operable and 12 with unresectable tumours), 22 with other non-small-cell type (12 with adenocarcinoma and 10 with large-cell type) and 45 with nonmalignant lung diseases. Elevated preoperative CYFRA 21-1 levels were identified in 63% of patients with squamous cell type (SqCC), 33% with adenocarcinoma, and 30% with large-cell carcinoma type. The diagnostic specificity of the assay was 96%. Positive CYFRA 21-1 levels were observed in 33% of stage I, 52% of stage II, 76% of stage IIIa and 83% of stage IIIb patients with SqCC type. Statistically significant differences were obtained between stages I and II and between II and IIIa, but not between stages IIIa and IIIb. Recurrence-free survival probability for patients with elevated serum CYFRA 21-1 levels before surgery was 63% (24/38) versus 92% (24/26) for patients with normal serum CYFRA 21-1 levels. However, the difference was not statistically significant when adjusted for the TNM stage (primary tumour, regional lymph node involvement, occurrence of distant metastasis). In 9 of the 10 patients with increased trend for CYFRA 21-1 during follow-up, elevated serum CYFRA 21-1 levels preceded (7) or coincided (2) with the clinical detection of tumour recurrence, providing a predictive value of an increased trend of 90%.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Iron starvation interferes drastically with the multiplication and virulence of Salmonella typhi mutants defective in enterochelin synthesis or enterochelin transport. Growth of these mutants is inhibited in the presence of human sera and unsaturated transferrin and is restored by fully saturated transferrin. The mutants exhibit decreased ability to grow in HeLa cell monolayers and are attenuated in mice. These findings are consistent with the S. typhi enterochelin system playing a role in the pathogenesis of typhoid fever.
