Interleukin-1 (IL-1) is radioprotective and induces both circulating colony-stimulating factor(s) (CSF) and IL-6 in mice. We evaluated the relationship among these three responses to IL-1 using anti-IL-1 receptor antibody 35F5. This antibody in vitro blocks responses of T cells and fibroblasts, but not of B cells or myeloid cell lines, to IL-1. Administration of 35F5 alone before irradiation re...

The present review describes the work carried out during the last 20 years in the field of the radioprotective activity and toxicity of several classes of organosilicon and organogermanium compounds (i.e. metallathiazolidines, metalladithioacetals, metallatranes and germathianes).

The use of radioisotopes and radiation is indispensable in the research of life science, especially in pharmaceutical sciences. Research topics in pharmaceutical sciences are mainly classified into three research fields as follows. (1) Trace elements in living systems and environment, where many kinds of tracers and neutron activation analysis are used. (2) Radioisotopes in the development of n...

Objective(s): Curcumin, a natural plant product, is commonly known as wonder drug of life, but the poor bioavailability of its free form has hindered its clinical development. The aim of the present study was to investigate the radioprotective effect of nanocurcumin on survival of mice under whole body X-ray irradiation. Materials and Methods: The Naval Medical Research Institute (NMRI) mice ra...

The aim of this study was to evaluate the radioprotective and reparative effects of compounds based on aloe vera, zinc, and copper against salivary gland dysfunction in Wistar rats. A total of 150 Wistar rats were randomly divided into 12 groups, in which the animals received aloe vera and/or zinc and copper. In eight of these groups the animals were also subjected to irradiation before or afte...

The study was aimed at the experimental assessment of the efficacy of heparin as radioprotector in condition of acute whole body γ-ray irradiation. The efficacy of the product was based on the 30-day survival rate and average life expectancy of dead irradiated animals. To reveal possible mechanisms of radioprotective effects of heparin the thymus mass, the number of leukocytes and colony format...

The aim of this study was to evaluate the individual and the synergetic radioprotective effect of lidocaine, amifostine, and pilocarpin on the parotid gland. Forty-nine rabbits were randomized into seven groups (n = 7)--control, irradiated sham-treated, irradiated/lidocaine-pretreated, irradiated/amifostine-pretreated, irradiated/pilocarpin-pretreated, irradiated/lidocaine + pilocarpin-pretreat...

The development of radioprotective agents has been a subject of intense research in view of their potential for use within a radiation environment, such as space exploration, radiotherapy and even nuclear war. Since no ideal, safe synthetic radioprotectors are available to date, the search for alternative sources, including plants, has been on-going for several decades. In the Traditional India...
