Fatty acids and their derivatives play a role in the response to ocular disease. Our current study investigated the effects of dietary mead acid (MA, 5,8,11-eicosatrienoic acid) supplementation on N-methyl-N-nitrosourea (MNU)-induced cataract and retinal degeneration in Sprague-Dawley rats. Experiment 1 was designed to inhibit cataract formation, with the dams fed a 2.4% MA or basal (<0.01% MA)...
Oligonol is a lychee fruit-derived functional food that contains oligomerized polyphenol compounds. Oligonol exhibits a number of beneficial biological effects, primarily due to its antioxidant activity. Retinitis pigmentosa (RP) is an inherited chronic degenerative disease affecting retinal photoreceptor cells. There is currently no effective therapy capable of stopping or reversing the progre...
BACKGROUND The present study was in quested to study the effects of β-sitosterol on methyl nitrosourea (MNU) induced mammary gland carcinoma in albino wistar rats. METHODS Animals were randomized and divided into four groups of eight animals each. Group I (sham control 1 % CMC in normal saline p.o.); Group II (toxic control, MNU 47 mg/kg, i.v); Group III (MNU 47 mg/kg, i.v + β-sitosterol, 10 ...
Effects of p.o. administration of sulfolithocholic acid disodium salt (SLCNa) and lithocholic acid sodium salt (LCNa) on N-methyl-N-nitrosourea (MNU)-induced colonic tumorigenesis were studied in conventional rats. Female F344 rats received either 0.5 ml of distilled water (DW) alone or DW containing 2.5 mg of MNU twice in 1 wk intrarectally. Then rats were fed freely on a basal diet (PCE-2) or...
BACKGROUND The aim of this study was to investigate the effect of N-methyl-N-nitrosourea (MNU) treatment followed by chronic Helicobacter pylori SS1 and H. felis colonization on the stomachs of C57BL/6 mice. The role of MNU and Helicobacter species in gastric carcinogenesis was also elucidated. METHODS A total of 69 C57BL/6 mice at 4 weeks of age were divided into 6 groups according to MNU tr...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The effect of dietary undegraded carrageenan (Viscarin 402) on colon carcinogenesis was studied in female inbred F344 rats. Weanling rats were fed semipurified diets containing 0 or 15% undegraded carrageenan. At 7 weeks of age, all animals except controls were given azoxymethane (AOM) s.c. at a dose rate of 8 mg/kg body weight per week for 10 weeks or methylnitrosourea (MNU) intrarectally at a...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
