    ABSTRACT: The effect of two novel β3-adrenoceptor (β3-AR) agonists SP-1f and SP-1h on human colon circular smooth muscle contractility and β3-AR mRNA expression have been determined. β3-AR is ascertained co-partecipates to the control of the gut motility. Isometric tension on human colon muscle strips was measured in response to increasing concentrations of SP-1f, SP-1h and (-)-Isoprenaline, alone and in the presence of Betaxolol, ICI 11,855 and SR 59230A (β1-, β2- and β3-AR antagonists, respectively). (-)-Isoprenaline concentration-dependently relaxed circular muscle strips with an EC50=0.32±0.06μM. Such an effect was antagonized either by the contemporaneously presence of Betaxolol and ICI 11,855 [(-)-Isoprenaline EC50=1.75±0.35μM, pKB=7.88±0.10] or by Betaxolol, ICI 11,855 and SR59230A [(-)-Isoprenaline EC50=3.49±0.38μM, pKB=8.51±0.14]. Besides, SP-1f and SP-1h concentration-dependently relaxed circular muscle strips with an EC50=0.35±0.07μM and 0.45±0.12μM, respectively. These values remained unchanged by blocking the β1- and β2-AR. The presence of SR59230A antagonized the relaxing effect of SP-1f (EC50=3.51±0.94μM, pKB=8.93±0.16) and did not modify the SP-1h relaxing potency. In colon circular smooth muscle and in mucosa, β3-AR mRNA expression levels were found to be 0.39±0.70 and 0.26±0.12 (P<0.05), respectively. Such results provide further evidence of the β3-adrenoceptor functional role in the human colon and the crucial contribution of SP-1f to the control of the gut dismotility.

    ABSTRACT: Differences in the actions of enteric neurotransmitters on colonic circular and longitudinal muscle layers have not been clearly determined, nor the possible existence of intrinsic myogenic phenotypes that might contribute to regional differences in human colon motor activity. The aim of this study was to analyze the direct pharmaco-mechanical coupling of carbachol (CCh) and vasoactive intestinal polypeptide (VIP) on human colonic smooth muscle strips and cells. Circular and longitudinal muscle strips and cells were obtained from 15 human specimens of ascending and sigmoid colon. Both isometric tension on muscle strips and contraction and relaxation on cells were measured in response to increasing CCh and VIP concentrations. Circular muscle strips of ascending colon were more sensitive to the effect of CCh than that of sigmoid colon, EC(50) values being, respectively, 4.15μmolL(-1) and 8.47μmolL(-1) (P<0.05), although there were no differences in maximal responses. No regional differences were observed in longitudinal muscle strips or in smooth muscle cells. Maximal responses to CCh were higher on circular than longitudinal muscle strips and cells throughout the colon. A greater sensitivity to VIP was observed in ascending colon compared with sigmoid colon, both in circular (EC(50:) 0.041 and 0.15μmolL(-1) , respectively, P<0.01) and longitudinal (EC(50:) 0.043 and 0.09μmolL(-1) , respectively, P<0.05) strips, and similar differences were observed in longitudinal smooth muscle cells (EC(50:) 44.85 and 75.24nmolL(-1) , respectively, P<0.05). Regional myogenic differences in pharmaco-mechanical coupling between the enteric neurotransmitters and smooth muscle contribute to the complex regional motor patterns of human colon.

    ABSTRACT: Lipoprotein lipase (LPL) is the crucial enzyme for intravascular catabolism of triglyceride-rich lipoproteins. Fatty acid synthase (FAS) is a key anabolic enzyme that catalyzes the terminal steps in the novo biosynthesis of 18:2n-6. The involvement of both LPL and FAS in tumor biology has been widely demonstrated in different studies and to verify whether there are regional differences in the expression of these enzymes in visceral adipose tissue from patients with colorectal cancer might be representative of events which sustain tumor growth. The objective of this study was to evaluate LPL and FAS activity and expression of their genes in adipose tissue adjacent to neoplasia and distant from it from patients operated for colorectal cancer. LPL enzymatic activity was evaluated by a fluorescent method and FAS activity by a radiometer assay. Reverse-transcription and real-time PCR were used to detect mRNA levels of two enzymes. Our findings show a significant reduction in both LPL and FAS gene expression and activity levels in adipose tissue adjacent to tumor lesion compared to those detected in paired tissue distant from neoplasia. These results underline the influence of tumor microenvironment on lipid metabolism in adipose tissue, demonstrating a tumor-induced impairment in the formation and lipid storing capacity of adipose tissue in patients with colorectal cancer.

    ABSTRACT: The leptin receptor is involved in modulating leptin activity, acting as a carrier protein. A link between leptin or leptin receptor and cancer development has been proposed and here, the hypothesis that leptin and its receptor might be implicated in colorectal cancer (CRC) progression and invasion was investigated. A total of 71 consecutive patients with CRC were enrolled in the study. Serum leptin and leptin receptor levels were evaluated by commercial ELISA kits. The multinomial logistic regression model showed a positive association of leptin and leptin receptor with advanced tumor stages, which was significant for the leptin receptor in stage IV of disease. High circulating levels of leptin receptor occur in patients with advanced stage of colon cancer, suggesting a role for leptin in cancer progression and aggressiveness.

    ABSTRACT: Fatty acid synthase is a common phenotype to various human cancers including those of prostate, colon, lung, endometrium, and stomach. Increased fatty acid synthase levels have been detected in serum from patients with breast and pancreatic cancer. In this study, serum levels of fatty acid synthase were measured in colorectal cancer patients at different stages of disease. Consecutive 67 patients with colorectal cancer were enrolled in the study. Serum levels of fatty acid synthase were examined by ELISA test. The Kruskal-Wallis test and the χ (2) method for trend have been used to analyze data. Serum fatty acid synthase levels of patients belonging to three groups of stage disease are statistically different. The patients with stage III and IV have significantly higher serum levels of fatty acid synthase than patients with stage I-II. There is a positive trend in serum fatty acid synthase levels from stage I-II to stage III and IV of disease. Fatty acid synthase levels are associated with the stage of disease in patients with colorectal cancer.

    ABSTRACT: We have investigated the presence of oestrogen receptor-related (ERR) mRNA in human colorectal tumour tissues and adjacent normal mucosa by reverse transcriptase and nested-polymerase chain reaction. ERRalpha was found in 100% of the patients and ERRgamma in approximately 30% while ERRbeta was not detected at all. The multiplex PCR analysis showed elevated levels of ERRalpha mRNA in tumour tissue compartment as compared to normal mucosa, whereas ERRgamma mRNA was found in lower levels but in both tissue compartments. In contrast, oestrogen receptor (ERalpha and ERbeta) mRNA levels were shown to be decreased in tumour tissues. A positive correlation was observed between ERalpha and ERbeta and between ERalpha and ERRalpha, respectively, in normal mucosa but not in tumour tissue. ERRalpha expression in tumour tissues significantly increased from TNM stages II to IV, whereas both ERs progressively declined. These findings suggest that ERRalpha, as well as the two ERs, might play a critical role in the progression of the colorectal cancer.

    ABSTRACT: Intestinal alkaline sphingomyelinase, by exerting a major role in dietary sphingomyelin digestion, is responsible for the generation of messengers able to trigger the rapid turnover and apoptosis in intestinal epithelial cells. Markedly reduced mucosal alkaline sphingomyelinase activity has been associated with human colorectal neoplasms. The aim of this study was to analyze the alkaline sphingomyelinase activity in feces from healthy subjects and colorectal adenocarcinoma patients and to correlate it with the enzyme activity in intestinal tissues. The enzyme activity was measured both in the intestinal samples from 12 healthy controls and 51 patients with colorectal adenocarcinoma (tumoral and paratumoral tissue) and in the fecal samples of 34 healthy subjects and 29 patients with adenocarcinoma. The relation between sphingomyelinase activity and Dukes' stage, cell differentiation degree, age, and gender was also analyzed. Alkaline sphingomyelinase was significantly decreased (P < 0.001; mean reduction >90%) in tumoral intestinal mucosa of patients compared with controls independently of Dukes' stage and tumor differentiation grade. Interestingly, the enzyme activity in histologically normal paratumoral tissues was statistically lower than control samples (P < 0.001). As occurs in neoplastic tissues, a relevant mean reduction (P < 0.0001; almost 90%) of alkaline sphingomyelinase was revealed in stool samples from tumor patients when compared with controls. These findings may have implications for cancer biology and perhaps also for the design of clinical test, thus suggesting that the fecal sphingomyelinase activity could really reflect the human intestinal mucosa enzyme level and could represent a new marker for human colorectal adenocarcinoma, mainly taking into account its early appearance in intestinal neoplasms.

    ABSTRACT: Little is known about the pathophysiology of diverticular disease. To compare passive and active stress and the response to carbachol of colonic smooth muscle specimens from patients with diverticular disease and patients with colon cancer. The effect of the NK2 receptor antagonist, SR48968, on electrically evoked contractions of circular muscle was also investigated. Sigmoid colon segments were obtained from 16 patients (51-83 years) undergoing elective sigmoid resection for diverticular disease and 39 patients (50-88 years) undergoing left hemicolectomy for non-obstructive sigmoid colon cancer. Isometric tension was measured on circular or longitudinal taenial muscle. Strips were stretched gradually to Lo (length allowing the development of optimal active tension with carbachol) and were also exposed to increasing carbachol concentrations. The effects of atropine, tetrodotoxin and SR48968 on electrically evoked (supramaximal strength, 0.3 ms, 0.1-10 Hz) contractions of circular strips from 8 patients with diverticular disease and 19 patients with colon cancer were also studied. Both passive and active stress in circular muscle strips obtained from patients with diverticular disease was higher than in patients with colon cancer (P < 0.05). Electrically evoked contractions were significantly reduced by atropine in all preparations and were virtually suppressed by combined SR48968 and atropine. Tetrodotoxin suppressed electrically evoked contractions only in patients with colon cancer, whereas a tetrodotoxin-resistant component was identified in patients with diverticular disease. The changes in both passive and active stress in specimens from patients with diverticular disease may reflect circular smooth muscle dysfunction. Acetylcholine and tachykinins are the main excitatory neurotransmitters mediating electrically evoked contractions in human sigmoid colon circular muscle.

    ABSTRACT: Many patients with gallstone disease continue to report gastrointestinal symptoms after cholecystectomy, but the predictive value of preoperative factors is not well understood. We aimed to investigate whether psychological symptoms can be associated with poor outcome after cholecystectomy in patients with gallstones and dyspepsia. A sample of 52 consecutive patients with uncomplicated gallstone disease and dyspepsia (conceived in a broader sense to include symptoms of the whole digestive tract) were assessed for psychological (revised 90-item Hopkins Symptom Checklist) and gastrointestinal symptoms (Gastrointestinal Symptom Rating Scale). One year after laparoscopic cholecystectomy, patients rated their gastrointestinal symptoms and were divided into improved and unimproved on the basis of the change in symptoms. Twenty-one (40.4%) patients did not improve after surgery. Improved and unimproved patients did not differ in terms of sex, age, education or illness duration. Unimproved patients showed significantly higher psychological and dyspeptic symptoms than improved patients before surgery. Logistic regression showed that psychological factors were significantly associated with unimprovement after surgery. Patients with gallstone disease and dyspeptic symptoms are unlikely to improve 1 year after surgery if they show psychological distress before surgery. Psychological symptoms were strongly associated with poor post-cholecystectomy outcome, thus highlighting the clinical relevance of joint assessment of psychological and gastrointestinal symptoms before surgery.

    ABSTRACT: The enzyme farnesyltransferase has emerged as an important target for anti-cancer therapies. Farnesyltransferase inhibitors have been introduced in clinical trials of subjects with colorectal cancer. We investigated Farnesyltransferase activity, beta-subunit Farnesyltransferase protein expression and its mRNA in patients with colorectal cancer and its relationship with clinicopathological features and K-ras mutation. Farnesyltransferase activity was determined by Farnesyltransferase [3H] SPA enzyme assay. Beta-subunit Farnesyltransferase protein expression was investigated by Western blotting and its mRNA by reverse transcriptase-polymerase chain reaction. K-ras mutation was detected by polymerase chain reaction amplification and restriction enzyme analysis. Multiple linear regression analysis was used to analyse relationships among age, sex, site of tumour, Dukes' stage, histological differentiation, K-ras mutation and Farnesyltransferase activity in normal mucosa and cancer. The levels of Farnesyltransferase activity and beta-subunit Farnesyltransferase protein expression were significantly higher in cancer than in normal mucosa. Moreover, tumours located on the right side, with mucinous histological differentiation and with K-ras mutation showed higher levels of Farnesyltransferase activity. Our findings suggest that Farnesyltransferase activity may be a potential marker of tumourigenicity. The differences in Farnesyltransferase activity in relation to histological grading, tumour location and K-ras mutation described here may constitute a starting point for investigating the causes of this variation within the large bowel.

    ABSTRACT: Cholecystokinin is the most important stimulant of postprandial gallbladder contraction, and a regulator of gallbladder fasting tone. The aim of this study was to evaluate the effect of dexloxiglumide on isolated human gallbladder contraction induced by cholecystokinin-octapeptide and to compare this effect to that of lorglumide and amiglumide, two glutaramic acid analogs of dexloxiglumide. The negative logarithms of the antagonist dissociation constant (pK(B)) values were 7.00 +/- 0.14, 6.95 +/- 0.11, and 6.71 +/- 0.10 for lorglumide, dexloxiglumide, and amiglumide, respectively. Dexloxiglumide produced a concentration-dependent rightward shift of the cholecystokinin-octapeptide curve, without affecting its maximal response. A similar effect was obtained both with lorglumide and amiglumide. Moreover, the slopes for the three antagonists did not differ significantly from unity. These data show that the three molecules have a potent antagonistic effect, of a competitive nature, on gallbladder cholecystokinin type 1 receptors. It may be concluded that dexloxiglumide, lorglumide, and amiglumide exhibit a promising therapeutic profile for biliary colic and other gastrointestinal disorders in which CCK1 receptors play important physiological roles.

    ABSTRACT: In vivo studies have demonstrated that somatostatin induces human gallbladder relaxation. To determine whether this polypeptide acts directly on the gallbladder muscle, its effect on strips of human gallbladder was studied in vitro. Strips of gallbladder were set up isometrically in an organ bath containing oxygenated Krebs' solution. Dose-response curves to cholecystokinin-octapeptide and carbachol were first established. The ability of somatostatin to cause relaxation under basal conditions and during 50% maximal stimulation by cholecystokinin-octapeptide (7.2 x 10(-8) M) and carbachol (3.5 x 10(-6) M) was assessed in 32 strips at 4.3 x 10(-6) M concentration which mimics the plasma concentrations found in patients with somatostatinoma and in 12 additional strips at 4.3 x 10(-8) M concentration. Somatostatin action on the intrinsic innervation by using electrical field stimulation (EFS) (200 mA 5 msec in duration, 30 Hz; 400 mA, 1 msec in duration, 10 Hz) was also evaluated in 39 strips. Somatostatin had no effect on the basal or carbachol-generated tensions. On the contrary, somatostatin (4.3 x 10(-6) M) reduced cholecystokinin-octapeptide-generated tensions by 8% (P < 0.001) and reduced EFS-generated tensions at 30 Hz by 7.7% (P < 0.01) and those at 10 Hz by 41.2% (P < 0.01). All responses to cholecystokinin-octapeptide and carbachol were abolished by dibutyryl-guanosine 3', 5'-cyclic monophosphate (5 x 10(-3) M) and atropine (10(-5) M), respectively (P < 0.0002 and P < 0.0002). All responses to electrical field stimulation were reduced or abolished by tetrodotoxin (2 x 10(-6) M) (P < 0.001 and P < 0.0001, respectively). Our findings show that somatostatin exerts its inhibitory action on the response to cholecystokinin-octapeptide and on the intrinsic innervation of the gallbladder smooth muscle. The probable neurotransmitter is the acetylcholine.

    ABSTRACT: Videolaparocholecystectomy is now regarded as the elective surgical technique for the treatment of cholelithiasis. In order to evaluate the feasibility and risks of videolaparocholecystectomy in patients with previous upper abdominal surgery the authors performed a retrospective case-control study in a group of 15 patients with cholelithiasis who had previously undergone gastrectomy for peptic ulcer (group A) and a control group of 15 patients with cholelithiasis who had not undergone upper abdominal surgery (group B). The control group was matched with the case group for age, sex, surgeon, indications for cholecystectomy (simple cholelithiasis, acute cholecystitis). The following parameters were compared in both groups: laparotomic conversion rate (33% in group A vs 20% in group B; p = 0.317), postoperative complications (0% in group A vs 13% in group B, p = 0.157), reoperations (0% in group A vs 13% in group B, p = 0.157), duration of surgery (median of 78 minutes in group A vs 80 minutes in group B; p = 1.000), duration of postoperative hospital stay (mean of 3 days in group A vs 3.5 days in group B, p = 0.507). None of the differences between the variables examined was statistically significant. The authors, conclude that videolaparocholecystectomy can be regarded as a safe and effective surgical technique for the treatment of cholelithiasis also in patients who have undergone previous upper abdominal surgery.

    ABSTRACT: To evaluate how the introduction of H2-receptor antagonists has modified the epidemiology of surgical management of peptic ulcer, we examined data records of patients operated on for gastric or duodenal ulcer in our Institute. Patients were divided into two groups: a) patients operated from 1970 to 1979 and b) patients operated from 1980 to 1992. The comparison between the two groups showed the following variations: decrease in male/female ratio from 8 to 4.4:1 (p = 0.0009); decrease in duodenal/ gastric ulcer ratio from 5 to 3.5:1 (p = 0.02); decrease in elective/emergency surgery ratio from 16 to 6.4:1 (p = 0.00006); increase in mean age of patients undergoing emergency operations from 51 to 58 years (p = 0.05); decrease in elective/emergency surgery ratio for gastric ulcer from 17.5 to 5.3:1 (p = 0.03), above all for the increase in emergency operations for hemorrhage; decrease in the prevalence of operations for refractory duodenal ulcer from 49% to 36% (p = 0.00009). Our findings show that H2-receptor antagonists have greatly modified the epidemiology of surgical treatment of peptic ulcer with a clear decrease in elective surgery for refractory duodenal ulcer in men and an increase in emergency surgery for gastric ulcer.

    ABSTRACT: To investigate the effects of cholecystectomy on gastric motor function, 13 patients with symptomatic gallstones were studied before and 8-12 months after surgery. Twelve healthy subjects entered the study as control group. The cutaneous electrogastrography and ultrasound examination of gastric emptying were simultaneously performed at pre- and post-prandial states. The dominant gastric frequency and its coefficient of variation were not affected by surgery. After cholecystectomy, an increase in normal 3 cpm wave percentage and a decrease in power ratio were found (P < 0.05 and P < 0.01, respectively). Gastric emptying recorded after cholecystectomy was faster than before surgery (306.9 +/- 15.9 min vs 336.9 +/- 11.8 min, respectively; P < 0.05). Such changes were associated with the relief of symptoms, and the comparison between patients and controls showed a normalization of the gastric electrical activity and gastric emptying after surgery. In conclusion, in symptomatic patients, gallstones are associated with motor dysfunctions, and cholecystectomy seems to induce a normalization of gastrointestinal motility.

    ABSTRACT: At present laparoscopic cholecystectomy represents the treatment of choice for symptomatic cholelithiasis. Authors performed a retrospective case-control study to evaluate whether cirrhosis associated with cholelithiasis increases the risk for morbidity of laparoscopic cholecystectomy. Twenty-one patients with cholelithiasis and cirrhosis (Child-Pugh class A or B) (group A) and 21 controls with cholelithiasis without cirrhosis (group B) entered the study. Controls were paired with cases for age, sex, and indication for cholecystectomy (simple cholelithiasis, acute cholecystitis). The two groups were compared for rate of conversion to open cholecystectomy (19% group A vs 9.5% group B; p = 0.31), morbidity (29.5% group A vs 5.3% group B; p = 0.17), median length of surgery (80 m in the two groups), and median time of postoperative hospitalization (5 days group A vs 3 days group B; p = 0.21). No difference among variables resulted to be statistically significant. Besides, neither common bile duct injuries nor intra or postoperative hemorrhages occurred in patients with cirrhosis. Authors conclude that the laparoscopic cholecystectomy can be considered a safe and effective surgical procedure also for patients with cholelithiasis associated with cirrhosis with a good residual hepatic function.

    ABSTRACT: Gastric surgery induces an increased incidence of gallstones. To investigate the changes in gallbladder kinetics after gastric resection, 20 male patients were studied: ten patients undergoing cholecystectomy for gallstones developed after Billroth II gastric resection and ten patients undergoing cholecystectomy for cholelithiasis without previous abdominal surgery. Longitudinal strips from the gallbladder wall were suspended in an organ bath and the isometric tension recorded. Dose-response curves to cholecystokinin-octapeptide and carbachol were obtained. Half the maximal response to cholecysto-kinin-octapeptide was 0.50 +/- 0.11 x 10(-7) M in the first group and 1.36 +/- 0.37 x 10(-7) M in the second group (P < 0.05). The ED50 to carbachol was 24.33 +/- 2.69 x 10(-7) M in the gastrectomy group and 40.39 +/- 5.01 x 10(-7) M in the control group (P < 0.01). There was no significant difference in the maximal contractile response either to cholecystokinin-octa-peptide or carbachol in the two groups. Our study shows an increased gallbladder sensitivity to cholecystokinin-octapeptide and carbachol in patients with gallstones developed after Billroth II gastric resection.

    ABSTRACT: The aim of this study was to determine the effect of Billroth II gastric resection (BII) without vagotomy on gallbladder contraction in response to meal and CCK-OP infusion. Fourteen duodenal ulcer patients were studied before surgery and six months postoperatively. Gallbladder volume was measured by real-time ultrasonography. After surgery, there was a significant increase in fasting gallbladder volume (P < 0.05). Postprandial gallbladder emptying was not significantly affected by gastrectomy apart from a trend towards a shorter t1/2 and a larger ejection volume. In addition, postoperative gallbladder relaxation was more pronounced at time 120 min. In response to cholecystokinin-octapeptide (CCK-OP) infusion, there was a significant decrease of t1/2 after BII and a prolonged contraction with a significantly reduced gallbladder volume. Our data show that the gallbladder response both to meal and CCK-OP infusion is modified after BII and a larger postoperative gallbladder volume may play a role in the pathogenesis of gallstone disease after gastric surgery.

    ABSTRACT: Ulcerative colitis is an inflammatory disease which, starting from the rectum, affects more or less extended tracts of the colon. Given that distal and extended forms are generally described as a single nosological entity, the authors aimed to verify whether there are any clinical differences between the two groups of patients with varying extents of disease. A retrospective review was made of data relating to 189 patients suffering from ulcerative colitis observed over a 90-months period. Only 111 cases were included in the study: all patients had undergone an endoscopic and histological diagnosis with a follow-up of over one year. Seventy-eight patients (41.26%) were excluded from the study because they had been lost during follow-up, or follow-up had lasted less than one year, or it had not been possible to perform pancolonoscopy. The 111 patients examined were subdivided into 2 groups: one (39 patients) with distal colitis, namely involving the rectum or recto-sigmoid, and the other (72 patients) with more extended disease. The extension of disease was evaluated on the basis of histological findings. The mean follow-up was 5 years and 11 months. The two groups were comparable for age, sex, number of annual attacks, maximum duration of disease-free periods, clinical evolution, predominant symptoms, extraintestinal symptoms and surgical treatment. Results were processed using Student's t test and the chi-square test.(ABSTRACT TRUNCATED AT 250 WORDS)
