We would like to submit the following correction to the published paper [1], the reason for this action is that the data in Table 3 were reanalyzed by one more accurate statistic method: On page 12, the sentence of paragraph three "OR and 95% CI were calculated by limited backward-LR (likelihood ratio) logistic regression analysis with adjustment by clinical variables" should be corrected into ...
effects, and the substantially lower dose. The main long-term hazardcarcinogenesis or leukaemogenesis-should be lower, possibly no more than a lifetime fatal cancer risk of 1% after 25 years.5 This case provides further evidence that total body irradiation may provide a useful additional form of management in cases of polymyositis resistant to conventional drug treatment, although a lasting eff...
The radioprotective effects of water-soluble derivate of propolis (WSDP) collected in Croatia, and single flavonoids, caffeic acid, chrysin and naringin in the whole-body irradiated CBA mice were investigated. Irradiation was performed using a gamma-ray source ((60)Co), and absorbed doses were 4 and 9 Gy. The efficiency of test components was evaluated when given intraperitoneally (i.p.) at dos...
introduction it has long been known that ionizing radiation can lead to detrimental effects in normal cells. in this light, radioprotective chemicals have been used to decrease morbidity or mortality caused by ionizing irradiation. this study aimed to evaluate the radio-protective effect of n-acetylcysteineagainst radiation-induced mortality in male mice. materials and methods 52 healthy male m...
A considerable amount of work has been reported in the literature on the effect of x-rays on antibody formation and immunity. With the exception of the reports from our laboratory,5"' the depressing effect of cobalt-60 gamma radiation upon immunity and antibody formation has not been reported. It would seem logical that x-rays and gamma rays should have a similar physiological effect. However, ...
The accumulation of p53 protein following whole body irradiation of adult mice was studied using a new polyclonal antibody to mouse p53. While dramatic accumulation of the protein was apparent in splenocytes, thymocytes and osteocytes no p53 protein accumulation was detected in the hepatocytes of the irradiated mouse. Thus, the upstream initiating signals that control the induction of p53 are c...
The influence of a host defense protein, lactoferrin (LF), contained in exocrine secretions such as milk, on radiation disorder was investigated. A total of 25 C3H/He mice in each of two groups were maintained with 0.1% LF-added and LF-free diets, respectively, for one month. The mice were then treated with single whole-body X-ray irradiation at a sublethal dose (6.8 Gy), and the survival rate ...
the relationship between the way in which normal hemopoietic stem cells respond to irradiation alone or in the presence of bleomycin sulfate (blm-s) and actinomycin 0 (act-d) was investigated. single doses of blm-s at 0.3 mg/kg and act-o at 0.10 mg/kg body weight were injected intravenously 1-6 hours prior to whole body irradiation and treatment was repeated twice more with time intervals. when...
The induction of thymic lymphomas by whole-body X irradiation with four doses of 1.8 Gy (total dose: 7.2 Gy) in C57BL/6 mice was suppressed from a high frequency (90%) to 63% by preirradiation with 0.075 Gy X rays given 6 h before each 1.8-Gy irradiation. This level was further suppressed to 43% by continuous whole-body irradiation with 137Cs gamma rays at a low dose rate of 1.2 mGy/h for 450 d...
