The effect of p.o. administration of tea on nitrosamine-induced carcinogenesis was investigated. Female A/J mice were given /V-nitrosodioth) lamine (NDEA) (10 mg/kg) p.o. once a week for 8 weeks and were killed 16 weeks after the last dose. More than 90% of the mice had forestomach and lung tumors. The animals had an average of 8.3 forestomach and 2.5 lung tumors/mouse. With 0.63 or 1.25% green...
One of the liabilities of the Apc(Min) mouse as a model for colon cancer is its lack of a robust tumor response in the large bowel. In our protocol, we treated the Apc(Min) mouse with azoxymethane, a colon-selective carcinogen. This protocol induced a 4-fold increase in the number of colon tumors. We utilized this protocol to investigate the possible mechanisms of inhibition of colorectal carci...
Background and Objective: Diabetes causes fertility disorders by interfering with the endocrine gland function. There are reports that, green tea and catechins could have anti-oxidant and hypoglycemic properties. Therefore, in the present study, we evaluated the effects of green tea aqueous extract and catechin influence on pituitary-gonadal axis in rat models of type 1 diabetes. Materials & M...
Green tea consumption is associated with chemoprevention of many cancer types. Fresh tea leaves are rich in polyphenolic catechins, which can constitute up to 30% of the dry leaf weight. While the polyphenols of green tea have been well investigated, it is still largely unknown, whether or not non-phenolic constituents also reveal chemopreventive and anti-metastatic effects. In this study, we i...
experts have found that natural environment could have positive impacts on patient’s treatment process. the impact of natural environment on mental state and lowering the stress level of the patients is undeniable. in this study, the impacts of natural environment on patient women in tehran general hospitals were investigated. after conducting a topical study of the issue on hand, using field o...
Green onions grown in soil and hydroponic medium contaminated with Escherichia coli O157:H7 and Salmonella were found to take up the pathogens in their roots, bulbs, stems, and leaves. Pressure treatment at 400 to 500 MPa for 2 min at 20 to 40°C eliminated both pathogens that were internalized within green onions during plant growth.
in this paper we investigate the green graphs for the regular and inverse semigroups by considering the green classes of them. and by using the properties of these semigroups, we prove that all of the five green graphs for the inverse semigroups are isomorphic complete graphs, while this doesn't hold for the regular semigroups. in other words, we prove that in a regular se...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
Aim: The aim of this in vitro study is to evaluate the change in color and shear bond strength of enamel bleached with different concentrations of carbamide peroxide and green tea extract solution. Materials and Methods: The specimens are grouped as follows:Group –A: 16 % carbamide peroxide,Group –B: 16% carbamide peroxide & green tea extract, Group –C: 21% carbamide peroxide, Group -D: 21% car...
BACKGROUND A major portion of the catechins in green tea is not absorbed in the small intestine. Bacteria in the colon convert nonabsorbed catechins into simpler phenolic compounds, which may also be absorbed. During the production of black tea, most catechins are polymerized to complex molecules called thearubigins. Little is known about the microbial degradation of these complex polyphenols, ...
