Antioxidants present in these products remain excellent candidates for local inhibition of the effects of TSNAs among SLT users.Although we provide discount chewing tobacco products, everything we supply is guaranteed by the manufacturer to be 100 percent genuine, so you can buy from us with complete confidence that you are getting a high quality product. One possible explanation for minimal cancer risk among human SLT users and inconsistent experimental results among animal studies is that SLT contains agents that inhibit carcinogenesis in vivo. However, the application of TSNAs together with water-soluble abstracts of SLT results in fewer tumors, and water-soluble extracts of SLT alone produce no tumors ( 20). For example, in animal models the chronic application of purified TSNAs to oral mucosa results in tumor formation ( 20). Furthermore, experimental evidence is inconsistent with regard to how large a factor these agents are in the production of tumors among SLT users.
The presence of TSNAs in SLT products has been a major concern expressed in the scientific literature and in the general press, but epidemiology studies conducted over the past 50 years have consistently documented that oral cancer risk in SLT users is elevated only minimally over non-users ( 15). Final results were calculated using the differences of areas under the β-PE decay curves between the blank and a sample and were expressed as micromole Trolox equivalents (TE) per g. All fluorescence measurements are expressed relative to the initial reading. The analyzer was programmed to record the fluorescence of β-PE every minute after addition of AAPH. Trolox (1.0μmol/L, Aldrich, Milwaukee, WI), a water-soluble analogue of vitamin E, was used as a control standard.

Louis, MO) was used as a target of free radical attack, with 2,2′-azobis (2-amidino-propane) dihydrochloride (AAPH, 4mM, Wako Chemicals USA, Richmond, VA) as a peroxyl radical generator. Briefly, in the final assay mixture (0.4ml total volume), β-phycoerythrin (β-PE, 16.7 nM, Sigma, St. ( 2) as modified for the COBAS FARA II ( 4). The procedure was based on a previous report of Cao et al. The automated ORAC assay was carried out on a COBAS FARA II spectrofluorometric centrifugal analyzer (Roche Diagnostic Systems Inc., Branchburg, NJ emission filter = 565 nm). The high antioxidant activity in smokeless tobacco may partially explain the low cancer risk associated with long-term use of these products. A significant linear relationship was observed between the overall antioxidant capacity and total phenolic content.
The tobacco products tested had a range of antioxidant activity from modest to high. The concentrations of polyphenols in these products also were determined. The antioxidant properties of 16 commercially available tobacco products were determined using an oxygen radical absorbance capacity (ORAC) assay. Although many studies have assessed the antioxidant properties of fruits and vegetables, much less is known about the antioxidant characteristics of another commonly ingested plant product, tobacco. These endogenous antioxidant agents are supplemented by dietary antioxidants, obtained mainly from plants. Mammalian cells have evolved a complex network of enzymatic and non-enzymatic molecules that protect them from the detrimental effects of reactive oxygen species (ROS).
