in order to study the effect of garlic crude extract on growth rate and histopathology of liver, kidney and intestinal bulb, 120 fishes with initial mean weight of 95±22 g were divided to four groups. they were fed with 0, 10, 20 and 40 g/kg garlic crud extract in food for 1 month. at the end of experimental period, the growth rate was estimated and samples from liver, kidney and intestinal bul...

The aims of this study were to assess the prevalence and type of activating point mutations at codons 12, 13, and 61 of the Ki-, Ha-, and N-ras genes in a series of early gastric carcinomas in white patients and to correlate these ras gene mutations, if any, with the histological type (Lauren classification), the type of growth pattern, and with the Helicobacter pylori status. Haematoxylin and ...

A selective procedure was used to isolate pectinolytic intestinal bacteria from human subjects. The three isolates with the greatest pectinolytic activity utilized pectin and a few related compounds as fermentable substrates for growth but did not utilize any other compound tested. Thus, their substrate utilization pattern was markedly different from that of previously described intestinal pect...

: This study aims to explore the relationship between syntactic and lexical complexity and also the relationship between different aspects of lexical complexity. To this end, speech monologs of 35 Iranian high-intermediate learners of English on three different tasks (i.e. argumentation, description, and narration) were analyzed for correlations between one measure of sy...

this study evaluated the effects of drinking thyme essence (dte) (zero, 0.10, 0.15 and 0.20 ml/l) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. a total number of 500 day old male broiler chicks (ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (crd)....

BACKGROUND Mucin immunoexpression in adenocarcinoma arising in Barrett's esophagus (BE) may indicate the carcinogenesis pathway. The aim of this study was to evaluate resected specimens of adenocarcinoma in BE for the pattern of mucins and to correlate to the histologic classification. METHODS Specimens were retrospectively collected from thirteen patients who underwent esophageal resection d...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...
