A SEQUENTIAL in vivo-ini vitr-o model system has been developed for studying carcinogenesis in the rat brain after transplacental expostire to ethylnitrosotirea (ENU) (Roscoe & Claisse, 1.976, 1978; Claisse et al., 1.978; Hince & Roscoe, 1.978a, b; Roscoe, 1980; Roscoe et al., 1980). Although cultures derived early in the latent period required prolonged passaging before becoming malignant or f...

background: arsenic is one of the most toxic metalloids. anemia and leukopenia are common results of poisoning with arsenic, which may happen due to a direct hemolytic or cytotoxic effect on blood cells. the aim of this study was to examine the effects of hydroalcoholic extract of nasturtium officinale on blood cells and antioxidant enzymes in rats exposed to sodium (meta)arsenite. methods: 32 ...

the present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vyaghouti. the experiment was done at agricultural and natural resources research center, ilam, iran at 2014. the experiment was a completely block design (crd) with four replications. saline factor was nacl salinity in seven levels (zero, 50, 100, 150, 200 and 250 mm). grap...

The specific contribution of each antioxidant enzyme to protection against the reoxygenation-associated oxidative stress after periods of hypoxia is not well understood. We assessed the physiological role of catalase during posthypoxic reoxygenation by the combination of two approaches. First, catalase activity of Nile tilapias (Oreochromis niloticus) was 90% suppressed by intraperitoneal injec...
