Previous work has shown that calcitonin inhibits eating by rats and that it affects several neurotransmitter systems suspected to play a role in alcohol consumption. The present study was an initial test of whether calcitonin does affect voluntary alcohol consumption by male Wistar rats with prolonged alcohol experience. Calcitonin (20 IU/kg) or saline was injected subcutaneously on 10 consecutive days when the rats (n = 20) had continual access to 10% (v/v) ethanol solution, and to food and water. Using a cross-over design, the effects of 40 IU/kg calcitonin vs. saline were then examined in a second 10-day treatment period. Similar patterns of effects were obtained with both calcitonin doses, but the patterns differed with alcohol, food, and water intake. Alcohol drinking showed biphasic changes with both doses, producing highly significant Treatment x Day interactions (p < 1E-10 and p = 6E-7): it was significantly reduced on the first day of calcitonin treatment and significantly increased on the last few days. Food intake was reduced on all calcitonin days although most markedly on the first. Water drinking was not altered on the first calcitonin day, but was greatly increased on the second, then gradually returned toward the baseline. In a second experiment, the animals were switched to 1 hr of alcohol access per day, and calcitonin (20 IU/kg) was administered periodically to one group 4 hr before the alcohol access. Alcohol drinking was significantly reduced in all cases when the calcitonin injection was preceded by at least 1 day without calcitonin.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

We studied prospectively the occurrence of hip fractures among the over 49-year-old urban populations (n = 88,206) in the cities Tampere, Jyv?skyl? and Kotka in 1989 and compared the results with a parallel Scandinavian multicentre study. During 1989, there were 266 inhabitants who were treated for a hip fracture, 213 of them were women. Women had in 132 cases a femoral neck fracture and in 81 cases a trochanteric fracture, and the corresponding numbers for men were 22 and 31. Among women, the total hip fracture incidence in Jyv?skyl? (n = 22) was the lowest when compared with the ones in Tampere (n = 47) and Kotka (n = 36). These incidences were on average lower than in the other Scandinavian cities studied in parallel. The all over ratio of femoral neck/trochanteric fractures was 1.1 in Tampere, 3.0 in Jyv?skyl? and 2.2 in Kotka and in Tampere, women had 9.3 times more femoral neck fractures than men. Our study showed that in Finland in three major cities the hip fracture incidence was lower than what has been similarly registered in corresponding urban populations in other Scandinavian countries. We also point out that the relative part of trochanteric fractures appears to be increasing. 相似文献

Short-term outcome analysis of a randomized study comparing laparoscopic vs open colectomy for colon cancer 总被引:19,自引:6,他引:13
A. M. Lacy J. C. García-Valdecasas J. M. Piqué S. Delgado E. Campo J. M. Bordas P. Taurá L. Grande J. Fuster J. L. Pacheco J. Visa 《Surgical endoscopy》1995,9(10):1101-1105
The authors examined the impact of the laparoscopic approach on the early outcome of resected colon carcinomas. The role of laparoscopic techniques in the treatment of colon carcinomas is questionable. Previous studies have suggested technical feasibility of surgical resections of these cancers by laparoscopic means and have implied a benefit to laparoscopic technique for patients undergoing colorectal resections. A prospective, randomized study was conducted comparing laparoscopic assisted colectomy (LAC) open colectomy (OC) for colon cancer. We present the preliminary results in relation to the short-term outcome and judge the feasibility of the laparoscopic procedure to as a way of performing accurate oncologic resection and staging. Benefit has been demonstrated with LAC in this setting. Passing flatus, oral intake, and discharge from hospital occurred earlier in LAC- than OC-treated patients The mean operative time was significantly longer in the LAC group than in the OC group. The overall morbidity was significantly lower in the LAC group. No significant differences were observed between both groups in the number of lymph nodes removed or the pathological stage following the Astler-Coller modification of the Dukes classification. The laparoscopic approach improves the short-term outcome of segmental colectomies for colon cancer. However, the further follow-up of these patients will allow us to answer in the near future whether or not the LAC may influence the long-term outcome.Presented at the annual meeting of the Society of American Gastrointestinal Surgeons (SAGES), Orlando, FL, USA, 11–14 March 1995 相似文献

Preliminary trial of a retroperitoneal approach for modified selective distal splenorenal shunt 总被引:1,自引:0,他引:1
A modified selective splenorenal shunt without portal-azygos disconnection through the left retroperitoneal approach was performed in 13 patients with cirrhosis of the liver and acute massive variceal hemorrhage. The anastomosis was end-to-side in 9 patients and end-to-end in 4 patients. All patients survived the operation. The post-operative course was extraordinarily benign; none of the patients developed clinical manifestations or biological evidence of hepatic dysfunction attributable to the operation. The only patient who died had an acute massive hemorrhage in the third postoperative week. None of the 12 surviving patients experienced further gastrointestinal bleeding. Dissection of the splenic and renal veins through the posterior retroperitoneal approach is technically easy. It may be the only alternative approach for portosystemic decompression in patients with dense intra-abdominal adhesions from previous operations involving the biliary tree or the upper gastrointestinal tract.The retroperitoneal approach for modified selective splenorenal portosystemic decompression is an effective method in the treatment and prevention of gastroesophageal bleeding in cirrhotic patients.

Résumé Chez 13 malades atteints de cirrhose hépatique avec hémorragie massive par varices oeosphagiennes, un shunt spléno-rénal sélectif modifié, sans déconnection azygo-portale, a été réalisé par voie rétropéritonéale gauche. L'anastomose a été termino-latérale dans 9 cas et termino-terminale dans 4. Tous les malades ont survécu à l'opération. Les suites opératoires ont été extraordinairement faciles; aucun malade n'a présenté de symptomes ou d'anomalie biologique d'altération fonctionnelle hépatique. Un seul malade est mort d'hémorragie massive à la troisième semaine postopératoire. Aucun des 12 survivants n'a présenté de récidive d'hémorragie digestive. La dissection des veines splénique et rénale par voie postérieure, rétropéritonéale, est techniquement aisée. Cette voie d'abord peut être la seule utilisable chez les malades opérés antérieurement sur les voies biliaires ou le tube digestif et qui présentent d'importantes adhérences intrapéritonéales.Le shunt splénorénal sélectif par voie rétropéritonéale est une thérapeutique préventive efficace des hémorragies gastro-oesophagiennes chez le malade cirrhotique.

Summary The cytostatic activity of five Bacillus Calmette-Guérin (BCG) strains (Pasteur, Evans, Tice, RIVM and Connaught) on human transitional cell cancer T24 cells was examined. A striking effect was noted even in 2-day cultures, and the effect was more pronounced when the cells were incubated for 5 days with different BCG strains alone. The concentrations needed were about the same as those used in clinical practice (109 colonyforming units of Pasteur strain in 100 ml buffered saline solution). Combination with mitomycin C or interferon--2b potentiated the cytostatic effect. A slight difference in cytostatic activity between different BCG strains was found. 相似文献

BACKGROUND/AIMS: Borrelia burgdorferi spirochete has been found both in bladder biopsies and the urine of patients with Lyme disease (LD) as well as in experimental animals. The urological symptoms in borreliosis resemble those of interstitial cystitis (IC): frequency, urgency and nocturia. The aim of this studies is to find the role of B. burgdorferi in interstitial cystitis. METHODS: We studied antibodies against B. burgdorferi from serum samples of 50 IC patients with two separate EIA tests. Patients with positive serology in both tests underwent cystoscopy and a bladder biopsy was taken. The presence of borrelia DNA was studied with borrelia-specific polymerase chain reaction (PCR), and with universal bacterial PCR. RESULTS: IgM class antibodies to B. burgdorferi were not found, but IgG antibodies were found in four samples (8%). This was higher than in the control material (2%). One patient's sample was strongly positive, whereas three samples were weakly positive. Bladder biopsies taken from the 4 patients were negative for borrelia DNA in both PCR tests. None of the seropositive patients had any symptoms consistent with LD. CONCLUSION: These results indicate that persistent infection of B. burgdorferi has no role in the etiology of IC. On the other hand a connection with a past borrelia infection and IC is not excluded. 相似文献

BACKGROUND AND AIMS: The use of antibiotic prophylaxis in open reduction and osteosynthesis of closed hip fractures is still controversial. The aim of this study was to demonstrate the effect of antibiotic prophylaxis in osteosynthesis of these fractures. MATERIAL AND METHODS: A total of 224 patients operated on between November 1994 and February 1998 in six hospitals by internal fixation for a fresh hip fracture were prospectively and randomly allocated to either a ceftriaxone antibiotic prophylaxis or no prophylaxis group and followed for one year. RESULTS: Within 6 weeks after the operation, 2.6% wound infections were recorded in the antibiotic group and 4.7% in the control group. Two (1.9%) of the five infections in the control group were deep infections (both sensitive to ceftriaxone). There were no statistically significant differences between the infection rates in both groups. However, when analyzing all complications recorded within 6 weeks, significantly more complications were found in the control group (p < 0.01). In the multivariate analysis the most important factor predicting postoperative complications was the lack of antibiotic prophylaxis. CONCLUSION: In this study the antibiotic prophylaxis group had significantly less postoperative complications than the control group within 6 weeks after the operation. 相似文献

Hepatopulmonary syndrome in candidates for liver transplantation 总被引:14,自引:0,他引:14

BACKGROUND: Hepatopulmonary syndrome (HPS) has been defined as a clinical triad, including chronic liver disease, gas exchange defects (increased alveolar-arterial PO2 difference irrespective of the presence of arterial hypoxemia), and widespread intrapulmonary vascular dilatations. We determined the incidence and the clinical and pulmonary functional characteristics of HPS in candidates for orthotopic liver transplantation (OLT) and tested their predicted accuracy. METHODS: We studied 80 patients with cirrhosis prospectively, and carried out contrast-enhanced (CE) echocardiography and lung function tests, including ventilation-perfusion (V(A)/Q) distributions. RESULTS: Fourteen patients had HPS (incidence, 17.5%). Patients with HPS (49 +/- 12 (+/-SD) years) had more cutaneous spiders, finger clubbing and dyspnea (P < 0.05 each) and a lower diffusing capacity (DLCO, 56 +/- 18% predicted; P < 0.001) than non-HPS patients (n = 66). Mild to moderate V(A)/Q inequalities and increased intrapulmonary shunt were predominant in HPS patients, but oxygen diffusion impairment was observed in those with hypoxemia (n = 8) only. The DLCO showed a considerable area under the receiver operating characteristic curve (0.89). CONCLUSIONS: HPS in cirrhotic patient candidates for OLT shows a high incidence and these patients present with distinctive clinical and functional features compared with non-HPS individuals. The presence of a low DLCO may be of help for the diagnosis of HPS. 相似文献
