Abstract
BACKGROUND Stereotactic body radiotherapy (SBRT) can emulate high dose rate brachytherapy (HDR-BRT) dose fractionation. We report our preliminary results using SBRT in monotherapy or pre-external-beam radiotherapy (EBRT) boost in patients with localized prostate cancer (LpC). The primary end point was the evaluation of both acute and late toxicities; secondary end point was the observation of prostate-specific antigen (PSA) nadir. PATIENTS AND METHODS Patients with LpC having prostate volume ≤90 cm(3) were enrolled in the present study. Patients were treated with SBRT alone or in combined modality (SBRT + EBRT). SBRT was performed using a CyberKnife System (Accuray Incorporated, Sunnyvale, California) and fiducial tracking system. RESULTS From February 2008 to July 2013, 21 patients for monotherapy (38 Gy/4 fractions) and 5 for combined modality (9.5 Gy/2 fractions plus 46 Gy/23 fractions EBRT) were enrolled. Androgen deprivation therapy (ADT) was administered in 16 of the 26 patients. The median pretreatment PSA was 9.4 (range, 4.5-14.3) ng/mL. All patients completed the planned therapy. Acute Grade 1 toxicity was observed in 18 patients, genitourinary (GU) in 12 / 26 patients, and gastrointestinal (GI) in 6 / 26 patients. Acute Grade 2 GU toxicity was reported in 1 / 26 patients, and Grade 2 GI toxicity was observed in 2 / 26 patients. The median PSA nadir was 0.15 (range, 0.02 = 1.4) ng/mL. Late toxicities were observed in 5 / 26 patients: Grade 1 GU (3 of 26), Grade 2 GU (1 of 26), and Grade 1 GI (1 of 26). Median follow-up was 21.5 (range, 8-65) months. CONCLUSIONS Our preliminary results of SBRT "simulating" HDR for LpC confirm a minimal toxicity and an optimal PSA response. The PSA nadirs appear comparable with HDR-BRT.

Abstract
Behcets disease (BD) is a chronic, relapsing, multi-system inflammatory disorder, clinically characterized by recurrent oral and genital ulcers, skin lesions, and uveitis. Other manifestations include arthritis, a positive pathergy test, thrombophlebitis, central nervous system disease and gastrointestinal ulcerations. The majority of affected individuals do not have life-threatening disease, although mortality can be associated with vascular-thrombotic and neurological manifestations. Currently, treatment of BD is symptomatic and empirical, and is tailored according to the severity of clinical features. In the past few years, isolated reports and case-series have been published on adult BD patients suggesting that inhibition of TNF-alpha is a promising therapeutic approach for severe ocular and various extra-ocular manifestations, including central nervous system involvement. In this study we present our promising experience with Etanercept therapy in juvenile-onset BD patients, characterized by refractory multiorgan involvement.

Abstract
Mutations in the X-linked gene cyclin-dependent kinase-like 5 (CDKL5) have been detected in patients presenting with seizures in the first few months of life and Rett syndrome features. Twenty-seven cases have been detected to date. Generalized intractable seizures, as infantile spasms, and generalized tonic-clonic seizures and myoclonic seizures characterize the clinical picture of CDKL5 mutations. Here we report on a patient who presented with sleep-related hyperkinetic seizures. Our observation and review of the literature suggest that a broader polymorphic electroclinical pattern with both generalized and focal seizures may occur in patients with CDKL5 mutations. A screen for CDKL5 mutations is useful in patients, mainly females, with a history of early onset intractable seizures and becomes mandatory when idiopathic infantile spasms and/or atypical Rett syndrome features are also present.

Abstract
BACKGROUND The study of gastric emptying rate of solids using radiopaque indigestible solid markers has been a poorly employed technique because some kinds of markers do not leave the stomach at the same time as the meal but during the interdigestive migrating motor complex (IMMC). The aim of this study was to evaluate whether markers of particular shape and size can be successfully employed for this purpose. METHODS Twenty-eight non-ulcer dyspeptic (NUD) patients and 20 healthy volunteers received a standard solid meal (790 Kcal) together with 20 small polyethylene radiopaque cylinders (5 mm x 2 mm in diameter). Gastric emptying rate was evaluated by ultrasound while the emptying of markers was simultaneously followed by X-rays using a brilliance intensifier. RESULTS Final emptying time (FET = time when the antrum area returns to fasting size) of digestible solids was 355+/-35 min in NUD patients versus 265+/-20 min in controls (P < 0.001). The gastric emptying curve of digestible solids correlated with emptying of markers both in NUD patients (r= +0.96) and in controls (r= +0.93). CONCLUSIONS The assessment of gastric clearance of radiopaque cylinders of 2 mm x 5 mm in size is a reliable tool for the study of gastric emptying rate of digestible solids. This is a readily available and easily performed test in any radiology unit.

Abstract
BACKGROUND Rabeprazole has been demonstrated to be a potent antisecretory agent and has been shown to be clinically effective in the treatment of acid-related diseases. AIMS It was to determine the efficacy of rabeprazole at 20 and 40 mg in addition to amoxicillin and clarithromycin in the treatment of active Helicobacter pylori-positive duodenal ulcers compared with omeprazole 40 mg. PATIENTS AND METHODS One hundred and twenty-seven patients were randomised into three treatment groups: 40 patients were treated with rabeprazole 40 mg daily, 42 patients with rabeprazole 20 mg daily and 45 patients with omeprazole 40 mg daily for 10 days. All patients received amoxicillin 1 g twice a day and clarithromycin 500 mg twice a day for 5 days. All patients were re-assessed at least 4 weeks after the end of the treatment. RESULTS According to the intention-to-treat (ITT) protocol, ulcer healing was observed in 90% of patients in the rabeprazole 40 group, in 85.7% in the rabeprazole 20 group and in 93.3% in the omeprazole 40 group. We observed H. pylori eradication in 90% ITT in the rabeprazole 40 group, in 80.9% ITT in the rabeprazole 20 group and in 88.8% ITT in the omeprazole 40 group. Statistical analysis did not show significant differences among the three groups. CONCLUSIONS A 10-day rabeprazole 20 mg regimen represents an efficacious and safe regimen for H. pylori eradication and ulcer healing.

Abstract
We describe a Sicilian family presenting a recessive form of hypercholesterolemia harboring a mutation of the autosomal recessive hypercholesterolemia (ARH) gene. In two of the three sibs, a 26-year-old male and a 22-year-old female, a severe hypercholesterolemia was diagnosed with very high levels of plasma cholesterol (15.9 and 12.2 mmol/l, respectively); tendon xanthomatas and xanthelasms were present and in the male proband was documented a diffuse coronary atherosclerotic disease with a rapid and fatal progression. Both the parents had normal or slightly increased levels of plasma cholesterol. All causes of secondary hypercholesterolemia were ruled out as well as an involvement of the LDL receptor or apoB genes. Beta-Sitosterol plasma levels were in the normal range. Cultured fibroblasts from skin biopsy from parents and the two probands displayed a normal ability to bind and degrade 125I-LDL. Direct sequencing of ARH gene demonstrated the presence of a 432insA mutation in homozygosis in the two probands; parents were heterozygotes for the same mutation. This mutation is the first report of a mutation of the ARH gene responsible for recessive forms of hypercholesterolemia in Sicily.

Abstract
BACKGROUND The aim of this study is to clarify the prevalence of gallbladder benign neoplasms, their ultrasonographic appearance and their relationship with gallbladder lithiasis and cancer. METHODS This study was carried out on 9000 consecutive patients having ultrasound of upper abdomen. Only adenomas and papillomas are considered as true benign neoplasms of the gallbladder. Adenomiomatosis and cholesterol polyps, often erroneously labelled as benign neoplasms, were excluded. Patients were followed-up by ultrasound every three months up to two years. RESULTS The prevalence of benign neoplasms was 1.19%. Papillomas were found more frequently than adenomas both in males (68.51%) and in females (94.33%). Gallstones were not concomitant with benign neoplasms in any case. Neither stones nor growth of gallbladder benign neoplasms were recorded within the two-year follow-up period. CONCLUSIONS Papillomas were more frequent than adenomas. No gallstone was concurrent with gallbladder benign neoplasms in our series. However, when gallstones are evidenced at ultrasound, further attention is recommended to discover probable concomitant neoplasms. Papillomas and adenomas more than 1 cm in diameter should be quarterly followed-up, while smaller masses could be six-monthly controlled. Surgery should be indicated for large-sized or rapidly growing masses because of the risk for cancer development.

Abstract
BACKGROUND The most widely used treatments for ulcer healing and Helicobacter pylori eradication consist of a 1-2 week regimen of a proton pump inhibitor plus two or three antimicrobials. AIMS To evaluate the efficacy, safety, cost, and tolerance of a three-day regimen with three antibiotics vs. a 10-day treatment with a proton pump inhibitor or vs. a ranitidine bismuth citrate triple therapy. METHODS Two hundred and twenty-one patients with endoscopically-proven H. pylori-positive duodenal ulcers were recruited to the study. Recruited patients were assigned to one of the following four regimens: (I) omeprazole 40 mg o.m. plus amoxycillin 1 g b.d. and clarithromycin 500 mg b.d. for 10 days (OAC: 55 patients); (ii) omeprazole 40 mg o.m. on days 1-5, plus amoxycillin 1 g b.d., clarithromycin 500 mg b.d. and metronidazole 500 mg b.d. on days 3-5 (OACM: 56 patients); (iii) ranitidine bismuth citrate 400 mg b.d. plus amoxycillin 1 g b.d. and clarithromycin 500 mg b.d. for 10 days (RAC: 54 patients); (iv) ranitidine bismuth citrate 400 mg b.d. on days 1-5, plus amoxycillin 1 g b.d., clarithromycin 500 mg b.d. and metronidazole 500 mg b.d. on days 3-5 (RACM: 56 patients). Fisher's exact test was used to compare data regarding healing and eradication in the four groups. RESULTS The intention-to-treat eradication and ulcer healing rates for the RACM regimen were 95% and 98%, respectively. Statistically significant differences were observed, relating to the eradication and healing of ulcers, between RACM and either the RAC or OAC regimens. CONCLUSION The three-day antibiotic therapy with amoxycillin, clarithromycin and metronidazole in addition to ranitidine bismuth citrate is a very effective anti-H. pylori regimen.

Abstract
The aim of this study was to compare the efficacy of two different 5-day proton pump inhibitor (PPI)-based triple therapies for Helicobacter pylori (Hp)-positive duodenal ulcers (DUs). Eighty-four patients received pantoprazole (Pan) 80 mg O.D. (once daily) for 1 week; 88 patients received omeprazole (Ome) 40 mg O.D. for 1 week. Patients of both groups received clarithromycin (Cla) 500 mg B.I.D. (twice daily) and amoxicillin (Amo) 1 g B.I.D. for 5 days. All of them were clinically and endoscopically investigated before enrollment (T0) and at 1 (T1), 6 (T2), 12 (T3), and 18 months (T4) after the end of the therapy. Hp status was determined by rapid urease test and by histology. At T1, we observed ulcer healing in 87.5% of the patients and Hp eradication in 83.7% of the Pan group (per protocol [PP]). In the Ome group, ulcer healing was noticed in 95.1% and Hp eradication in 95.1% (PP). We found no statistical differences between the groups (PP). At the end of the follow-up, we found a healing rate of 100% both in the Pan group and in the Ome group; an eradication rate of 98.4% and 100% was observed in the Pan group and in the Ome group, respectively. We found no statistical differences between the groups (PP). Hp eradication was associated with an improvement in the grade of gastritis at T1, remaining unchanged until T4. In conclusion, the efficacy of the Pan treatment was similar to the Ome treatment.

Abstract
BACKGROUND An external straightener for colonoscopy which enables proper compression of the abdomen during the entire examination has been developed. METHODS Beginning January 1, 1997, patients undergoing outpatient colonoscopy were subjected to either manual abdominal compression or compression with an external straightener. Two hundred patients were divided into two groups of 100 patients each: group A (colonoscopy using traditional methods; 38 men, 62 women, mean age 59.6 years, range 18 to 80) and group B (colonoscopy with the help of the external straightener; 40 men, 60 women, mean age 59.8 years, range 16 to 75). Fifteen minutes after the examination, each patient completed a form that assessed the degree of pain during the procedure (no pain, mild, moderate, severe). RESULTS The ileocecal valve was reached in 89 cases in group A and 94 cases in group B. The average time required to reach the valve was 9.34+/-4 minutes (range 4 to 25) in group A and 6.97+/-3.37 minutes (range 2 to 21) in group B (p<0.001). With regard to the degree of pain, the results for groups A and B were, respectively: no pain = 25% and 40%, mild = 29% and 34%, moderate = 30% and 20%, severe = 16% and 6% (p< 0.001). CONCLUSIONS The external straightener reduced examination time and decreased the degree of patient pain compared with traditional methods.

Abstract
BACKGROUND Helicobacter pylori eradication has become the standard treatment for peptic ulcer disease. H. pylori-eradicating triple therapy with omeprazole plus two antibiotics has been used until recently; however, the efficacy of pantoprazole and antibiotics for H. pylori eradication has not been researched thoroughly until now. The aim of this randomized clinical trial was to verify the efficacy of triple oral therapy comparing the effects of pantoprazole using two different doses versus omeprazole twice daily in H. pylori eradication, in ulcer healing and relapses, and in gastritis improvement. MATERIALS AND METHODS We enrolled 243 patients with H. pylori-positive duodenal ulcer and randomized them into three treatment groups: 84 patients (group Ome40) were assigned to receive omeprazole, 20 mg twice daily, plus amoxicillin, 1 gm twice daily, and clarithromycin, 500 mg twice daily for 10 days; 79 patients (group Pan40) were treated with pantoprazole, 40 mg daily, plus amoxicillin and clarithromycin at the same doses as those of group Ome40; and 80 patients (group Pan80) were treated with pantoprazole, 40 mg twice daily, plus amoxicillin and clarithromycin at the same doses as those of group Ome40. RESULTS Ulcer healing was observed in 81 of 84 patients (96.4%) in group Ome40; in 66 of 79 patients (83.5%) in group Pan40; and in 77 of 80 patients (96.2%) in group Pan80. H. pylori was eradicated in 79 of 84 patients (94%) in group Ome40; in 63 of 79 patients (79.7%) in group Pan40; and in 75 of 80 patients (93.7%) in group Pan80. CONCLUSIONS We found that 10-day triple therapy with amoxicillin, clarithromycin, and either pantoprazole, 80 mg daily, or omeprazole, 40 mg daily, is highly effective in ulcer healing and is very well tolerated, achieving the 90% cure recommended for an ideal first-line anti-H. pylori positive duodenal ulcer treatment regimen.

Abstract
RATIONALE AND OBJECTIVES To assess and compare gastrointestinal (GI) rates in young and aged men under homogeneous conditions of weight and dietetic habits. METHODS Gastric emptying time was evaluated by ultrasound. GI transit time was studied radiologically using radiopaque markers. RESULTS Final gastric emptying time in elderly subjects was 335 +/- 31 minutes (mean +/- SD) versus 245 +/- 25 minutes in young subjects (P < 0.001). Total GI transit time showed no significant difference between the two groups. Intestinal transit time includes both small bowel and colonic transit; small bowel and colonic transit was not separated in this study. CONCLUSIONS Delayed gastric emptying of solid foods could result from progressive autonomic nerve dysfunction occurring with aging. The stomach does not seem to be the segment of the digestive tract that is primarily responsible for the alteration of total GI time.

Abstract
The association of Helicobacter pylori and functional dyspepsia is not well defined. The role of H. pylori on dyspeptic symptoms is still controversial. The aim of this study is to confirm the efficacy of H. pylori eradication by two different commonly used treatment regimens, as well as to examine the improvement of the dyspeptic symptoms by eradicating H. pylori. H. pylori functional dyspepsia is prevalent in people over 60 years old. In this age group we treated 126 patients with bismuth plus metronidazole and amoxicillin (group A, 67 patients) versus omeprazole plus amoxicillin (group B, 59 patients). Results were statistically analyzed utilizing the Wilcoxon signed-rank test, McNemer test and chi-square test; P < 0.05 was considered significant. Two months after the end of therapy we observed an eradication rate of 66.1% in group A vs 64.3% in group B. All treated patients showed improvement in symptomatology. Although there was no significant difference between patients in whom H. pylori was or was not eradicated within the respective groups, when examining all H. pylori-positive patients versus H. pylori-negative posttreatment patients, there was a significant reduction (P < 0.05) in all four symptoms of functional dyspepsia measured. In conclusion, we suggest that patients treated with H. pylori-eradicating therapeutic regimens have an improvement in functional dyspepsia symptoms. We shall prefer the dual therapy as compared to the triple therapy. We believe that eradicating treatment to eradicate H. pylori in the elderly patients with H. pylori-related functional dyspepsia will reduce health care costs by reducing the number of subsequent visits.

Abstract
Gastric emptying can be modified by different physiologic conditions such as aging, menstrual cycle and pregnancy. Few studies in the literature have compared the gastric emptying rate of solid meals in normal subjects of varying size. The purpose of this work is to evaluate the gastric emptying rate of solid meals to determine whether body mass index (BMI) and gastric emptying rate correlate. Both ultrasonographic and scintigraphic techniques have been employed. Twenty-four healthy male subjects, divided into two groups, participated in the study. Our results demonstrate a significant correlation between gastric emptying and BMI. We conclude that variability of BMI must be taken in account when measurements of gastric emptying of solid food are performed.

Abstract
AIM To compare the efficacy and safety of triple therapy with omeprazole plus amoxycillin and clarithromycin vs. ranitidine bismuth citrate plus amoxycillin and clarithromycin in the treatment of Helicobacter pylori-associated duodenal ulcers. METHODS Eighty-one patients with duodenal ulcers were randomized to the following treatments: 39 cases with amoxycillin 1 g b.d. and clarithromycin 500 mg b.d. for 1 week plus omeprazole 20 mg b.d. for 2 weeks (omeprazole + amoxycillin + clarithromycin (OAC)), and 42 cases to the same regimen of amoxycillin and clarithromycin for 7 days plus ranitidine bismuth citrate 400 mg b.d. for 2 weeks (ranitidine bismuth citrate + amoxycillin + clarithromycin (RbAC)). Upper gastrointestinal endoscopy was performed together with a rapid urease test and histological examination of antral and corpus biopsy samples prior to treatment and 4 weeks after the end of therapy. RESULTS Thirty-four patients in the OAC group and 38 in the RbAC group completed the treatment and 4-week follow-up. H. pylori was eradicated in 30 of 34 patients (88%) in the OAC group and in 32 of 38 patients (84%) in the RbAC group according to a per-protocol analysis (P = N.S.). Thirty-three (97%) patients treated with OAC and 36 (95%) treated with RbAC presented healed duodenal ulcers at 4 weeks (P = N.S.). On an intention-to-treat basis there was no difference in H. pylori eradication between the OAC (77%) and RbAC groups (76%); duodenal ulcer healing was achieved in 85 and 86% of patients in the OAC and RbAC groups, respectively (P = N.S.). CONCLUSION The OAC and RbAC triple therapy regimens proved equally effective in both H. pylori eradication and in duodenal ulcer healing.

Abstract
RATIONALE AND OBJECTIVES Gallbladder wall thickness was measured by ultrasound in 16 patients with ascites caused by liver cirrhosis and in 16 noncirrhotic patients with ascites. This study was performed to evaluate if gallbladder wall thickening could differentiate cirrhotic ascites from ascites due to other causes. METHODS Gallbladder thickness was measured by duplex ultrasound in 16 cirrhotic patients with ascites and in 16 noncirrhotic patients with ascites. Measurements of portal vein flow and serum albumin also were performed. RESULTS Gallbladder wall thickness was 0.76 +/- 0.21 cm in cirrhotic patients and 0.24 +/- 0.09 in noncirrhotic patients (P < 0.001, Student's t test for unpaired data). Gallbladder wall thickening was significantly more frequent in patients with cirrhotic ascites than in patients with noncirrhotic ascites (P < 0.001, chi-square test). CONCLUSIONS The authors feel that the ultrasound finding of gallbladder wall thickening in patients with ascites is highly predictive of liver cirrhosis diagnosis.

Abstract
The efficacy of pneumatic dilatation with Rigiflex balloons as a treatment for pyloric peptic stenosis was tested in 18 patients. The patients underwent endoscopic dilatation in one sitting, the size of the balloons being gradually increased for a total of 3 minutes. Patients were also treated with omeprazole in the follow-up period. Pneumatic dilatation of upper digestive tract strictures has proved to be an effective and safe technique, showing remarkable advantages over the traditional surgical treatment. It could represent the first step in a therapeutic approach.

Abstract
Levosulpiride, a dopaminergic antagonist was compared in a double-blind randomized study with domperidone for treatment of functional dyspepsia in 50 patients divided into two groups of 25 subjects each. Group I received 25 mg levosulpiride 3 times daily, group II received 10 mg domperidone 3 times daily, all for 30 days. Periodic clinical examination at days 0, 7, 15, 30 showed symptomatic changes. Gallbladder and gastric emptying was studied by ultrasonography at the start and end of treatment. Both drugs had a positive influence on dyspeptic symptoms and on gastric and gallbladder emptying, but the latter parameters were improved significantly more effectively by levosulpiride. As to tolerability, there have been 3 drop-outs and a further 6 patients complained of sides effects that did not require suspension of treatment.

Abstract
Gastric emptying of digestible and indigestible solids has been simultaneously evaluated in healthy humans. Gastric emptying of indigestible solids occurs simultaneously during the emptying of digestible solids. The knowledge of the mechanism responsible for gastric emptying of both digestible and indigestible solids may contribute to improve physiologic insight in this field and to develop further clinical applications.

Abstract
The pancreatic duct or at least parts of this structure can be demonstrated today by sonography in 50-82% according to various authors. We have measured the caliber of the sonographically visualized pancreatic duct in 20 normal subjects after physiological stimulation with meal. The mean caliber of the duct markedly increased after meal. During dilatation a longer segment of duct is more clearly visualized. It is possible to document an increase of caliber of Wirsung duct "in vivo" as an evident sign of pancreatic secretion.

Abstract
Forty-three patients with active duodenal ulcer and Helicobacter pylori positivity in gastric antrum were randomly assigned to either omeprazole treatment (20 mg once a day) or ranitidine treatment (300 mg once a day) for 28 days. Re-evaluation of the patients (clinical and endoscopic examination and assessments for H pylori detection) was repeated after 2 weeks and at the end of the treatment. Healing rates in the omeprazole group were 40% after 2 weeks and 90% after 4 weeks, in the ranitidine group ulcer healing was recorded in 20% of patients after 2 weeks and in 80% after 4 weeks. Differences between treatments at 2 and 4 weeks were not statistically significant. Clinical response (disappearance of ulcer-related symptoms) was better in the omeprazole group at 2 weeks (p less than 0.05) but not at 4 weeks. At the end of the trial H pylori positivity in gastric antrum disappeared in 95% of the patients treated with omeprazole and in 5% of the patients who received ranitidine (p less than 0.001). The results confirm the effectiveness of omeprazole in short-term treatment of duodenal ulcer and re-emphasize the powerful activity of the drug on H pylori infection.

Abstract
We measured simultaneously gastric emptying of digestible and indigestible solids in 10 normal subjects and in 14 insulin-requiring diabetic patients. Our results demonstrate that in both diabetics and in controls the gastric emptying of digestible and indigestible solids occurs during the same phase of gastric motor activity, i.e. during the post-prandial period. However, gastric emptying of both digestible and indigestible solids is delayed in diabetic patients compared to controls.

Abstract
Gastric emptying was studied in 10 insulin-treated, long-standing, diabetic out-patients with upper gastrointestinal, dyspeptic symptoms. Autonomic neuropathy, mucosal lesions and chloropeptic hyposecretion were excluded. Gastric emptying of a labelled solid meal (99mTc-sulphur colloid-infiltrated chicken liver) was clearly delayed by comparison with normal subjects: the mean gastric emptying half-time was almost 5-times longer (245.6 vs 52.5 min), and the gastric emptying rate at 120 min was 75% slower. Cisapride 10 mg i.v. significantly accelerated both parameters, and placebo had no effect upon them. In conclusion, gastroparesis may be present in diabetics without autonomic neuropathy, and cisapride may improve gastric emptying in such patients.

Abstract
The effect of simple and mixed copper(II) complexes of L-tryptophan (trp) and L-phenylalanine (phe) on the gastric acid secretion was investigated in Shay rats. Graded doses (from 15 to 75 mg/kg) of [Cu(trp)2(H2O)], [Cu(phe)2(H2O)] and [Cu(trp)(phe)(H2O)], administered i.g., caused a progressive inhibition of gastric acid secretion. The antisecretory activity of the mixed complex, [Cu(trp)(phe)(H2O)], was significantly greater (ID50 = 33 +/- 3 mg/kg) than that of the simple complexes [Cu(trp)2(H2O)] (ID50 = 48 +/- 3 mg/kg) and [Cu(phe)2(H2O)] (ID50 = 43 +/- 3 mg/kg). At the experimental conditions of intragastric pH, the different biological activities were directly related to the percentage of neutral species present in solution as determined by means of potentiometric measurements (at 37 degrees, I = 0.15 mol dm-3 in NaClO4). A possible mechanism of action of the investigated compounds is discussed.

Abstract
Gastric acid responses to intragastric administration of graded doses (14-30-45 mg/Kg) of copper (II) complexes with aminoacids (two simple complexes, Cu-Trp2 and Cu-Phe2, and on mixed complex, Cu-Trp-Phe) were investigated in Shay rats. The results (% inhibition of H+ mEq/4h) shown that graded doses of copper complexes caused a progressive inhibition on gastric acid secretion, and that percentage inhibition values were, for all complexes, in linear correlation with employed doses. A possible mechanism by which copper complexes affect gastric acid secretion is discussed.
