Abstract: a performance assay was conducted to study the effects of dietary electrolyte balance (eb) and crude protein levels on deposition of collagenous protein (cp) and the non collagenous protein (ncp) in the broiler bone matrix femurs. the broilers were fed diets with 20.0 or 23.0% of cp combined with 0, 50, 100, 150, 200, 250, 300, or 350 meq/kg of eb from 1 to 21 and from 22 to 42 days. the experiment was analysed as a completely randomised design with a factorial arrangement of treatments (eight levels of eb and two levels of pc) and four replications. the higher value of ncp deposition in the bone at 21 days and cp at 22 and 42 days was obtained with diets containing eb values from 150 to 200 meq/kg. effect of dietary protein level on cp and ncp at 21 days old was observed. there was no effect of eb and crude protein levels on ncp deposition at 42 days. effect of eb level on the cp deposition in the femurs of broilers at 42 days old was noticed. the electrolyte balance affected bone protein deposition in young broilers.

Abstract: Collagenous gastritis (CG) is characterized by patchy subepithelial collagen bands. Effective treatment and the clinical and histological outcome of CG in children are poorly defined. The aim of this study is to summarize the published literature on the clinical outcome and response to therapy of pediatric CG including two new cases. We performed a search in Pubmed, OVID for related terms; articles including management and clinical and/or endo-histologic follow up information were included and abstracted. Reported findings were pooled in a dedicated database including the corresponding data extracted from chart review in our patients with CG. Twenty-four patients were included (17 females) with a mean age of 11.7 years. The clinical presentation included iron deficiency anemia and dyspepsia. The reported duration of follow up (in 18 patients) ranged between 0.2-14 years. Despite most subjects presenting with anemia including one requiring blood transfusion, oral iron therapy was only documented in 12 patients. Other treatment modalities were antisecretory measures in 13 patients; proton pump inhibitors (12), or histamine-2 blockers (3), sucralfate (5), prednisolone (6), oral budesonide in 3 patients where one received it in fish oil and triple therapy (3). Three (13%) patients showed no clinical improvement despite therapy; conversely 19 out of 22 were reported with improved symptoms including 8 with complete symptom resolution. Spontaneous clinical resolution without antisecretory, anti-inflammatory or gastroprotective agents was noted in 5 patients (4 received only supplemental iron). Follow up endo-histopathologic data (17 patients) included persistent collagen band and stable Mononuclear cell infiltrate in 12 patients with histopathologic improvement in 5 patients. Neither collagen band thickness nor mononuclear cell infiltrate correlated with clinical course. Intestinal metaplasia and endocrine cell hyperplasia were reported (1) raising the concern of long term malignant transformation. In summary, CG in children is a chronic disease, typically with a variable clinical response and an indolent course that is distinct from the adult phenotype. Long term therapy usually inclused iron supplementation but cannot be standardized, given the chronicity of the disease, variability of response and potential for adverse events.

Abstract: ted luminal mucosal complications of adult celiac disease Review (8611) Total Article Views Authors: Hugh J Freeman Published Date February 2009 Volume 2009:2 Pages 9 - 12 DOI: http://dx.doi.org/10.2147/CEG.S4777 Hugh J Freeman Department of Medicine (Gastroenterology), University of British Columbia, Vancouver, BC, Canada Abstract: Celiac disease is a gluten-dependent intestinal disorder that appears to be associated with several clinical conditions. Some involve the luminal mucosa of the stomach and intestinal tract and may, occasionally, complicate the course of celiac disease. Collagenous colitis has been associated with celiac disease and may lead to chronic diarrhea. Conversely, some of these clinical disorders that involve the luminal mucosa of the stomach and intestine may represent the initial clinical presentation of celiac disease. These disorders should be considered in patients with celiac disease who develop recurrent or refractory symptoms despite adherence to a strict gluten-free diet. Detection of collagenous disorders that affect the luminal mucosa of the stomach or intestinal tract may result in recognition of underlying celiac disease.

Abstract: a biomechanical / morphological study in rats? abdominal wall healing and meloxicam was performed in 120 male wistar rats. the 60 animals in the control group were injected meloxicam im (0,5mg.kg-1) or saline soluction (nacl 0,9%) in the initial four consecutive days. the 60 animals in the experimental group carried out standart laparotomie and closure. each animal in the initial four days was injected meloxicam or saline soluction in the same way of the control group. about the 5th, 10th or 15th post-operative day the animals weith-body were measured and segments of the operated abdominal wall was submitted to tensile strength test and hystological analysis (collagenous and macrophages counters with spetial pc-software). statistical analysis was considered at 5%. the body weight records showed better performance in the animals injected with meloxicam at five-day observation, probably due to less pain in post-operative period. the tensiometer test showed no statistical differences in all groups, just like the histological counters and qualitative analysis of collagenous tissue and macrophages, showing that meloxicam had no interference in abdominal wall healing. the findings led us to conclude that meloxicam doen?t provide biomechanical and morphological healing alterations in rat?s abdominal operative scars.

Abstract: this work aimed to study the effects of l-glutamic acid (l-glu) and k vitamin on the biochemical composition (collagenous proteins, cp; non collagenous proteins, ncp; and total proteins, tp) in femurs of broilers. the experiment which lasted for 14 days, was carried out in a completely randomized design in a 2 × 4 factorial with two levels of l-glutamic acid (6.25% and 12.5%) combined with four levels of k vitamin (0.02; 0.2; 2.0 and 20.0 mg of feed) each combination with four replicates of 10 animals. it was used avian farm male broilers at 1 day of age, reared in electrically heated batteries with raised wire mesh floors and they were fed ad libitum with a basic diet containing essential l-amino acids, minerals and k vitamin. at the end of the experiment, the broilers were sacrificed through cervical dislocation and their femurs were removed, measured, fat removed and weighted. it was not observed a significant interaction among lglutamic acid and k vitamin for the studied parameters. the non-collagenous protein levels were higher and the collagenous proteins levels were lower in the femurs of the animals fed with 6.25% of l-glu. however, the total protein levels were not affected by the levels of l-glutamic acid and k vitamin. the levels of k vitamin had a decreasing quadratic effect on the levels of non-collagenous proteins and increasing effect on the level of collageonous proteins in the femurs. the composition on collagenous and non collagenous proteins can be used as a biochemical marker of leg abnormalities caused by low level of non-specific nitrogen.
