Background . Ionizing radiation is an effective antitumor therapy, but it has a serious negative effect on the immune system requiring use of reaction prevention and reduction methods. Neutrophils are sensitive element both in interaction with tumor tissue response to injury. Aim To evaluate functional activity peripheral blood neutrophils by chemiluminescent analysis patients anorectal cancer ...

Radiation has been considered an enigma to the general public and the use of radiation for therapeutic and other uses has always been associated with some skepticism. Presently, ionizing radiation is being used in a large number of therapeutic, industrial and other applications apart from for the generation of nuclear power, developing new varieties of high-yielding crops and enhancing storage ...

Previous studies have shown that the radioprotector WR1065 protects against mutagenesis across a wide concentration range (i.e., 40 MMto 4 HIM)but protects against cell killing by ionizing radiation at concentra tions greater than 1 HIM.Other work has demonstrated that many genes are induced or repressed after exposure of cells in culture to ionizing radiation, but the actual inducing agents fo...

Ethanol extract (FRE) and water extract (FRW) of Ficus racemosa (family: Moraceae) were subjected to free radical scavenging both by steady state and time resolved methods such as nanosecond pulse radiolysis and stopped-flow spectrophotometric analyses. FRE exhibited significantly higher steady state antioxidant activity than FRW. FRE exhibited concentration dependent DPPH, ABTS(*-), hydroxyl r...

BACKGROUND The interaction between ionizing radiation and substances in cells will induce the production of free radicals. These free radicals inflict damage to important biomolecules such as chromosomes, proteins and lipids which consequently trigger the expression of genes which are involved in protecting the cells or repair the oxidative damages. Honey has been known for its antioxidant prop...
