The present work aims to detect the effects of gamma ray radiation emitted from Co-60 on several blood parameters (PCV, Hb, WBCs and RBCs) of male chickens. Also, the potential antioxidant impact of grape seeds oil exposed to cold plasma as a protective material to lower the damage caused by gamma ray was tested for a long time and low dose rate. Healthy male chickens were used in this study which had an age range of 2 to 3 months and a weight range of 1.5 to 2 kg. Animals were kept in plastic cages (100 x 400 x 40 cm dimensions) within humidity and temperature preserved at limited values. Four experimental groups were included; the first was the un-exposed control. The second group was administered with a dose of grape seed extract. The third group was exposed to gamma ray radiation only. The fourth group was administered with a dose of grape seed extract and irradiated with gamma waves. Forty male chickens were used in this work as they were parted and administered with the selected doses. The control group was considered as the first group that contained 10 male chicken without being exposed to waves of gamma rays. The next group also contained 10 male chicken irradiated with 5 Gy/lh at interval 7 hour/day for 20 days as second group. Another group contained 10 male chicken and was dealt with oil of grape seed 400 mg/kg wt) with orally administered dose for 20 days as third group. The fourth group contained 10 male chicken irradiated with 5 Gy/h at interval of 7 hour/day for 20 days and dealt with orally administered dose (400 mg/kg wt) of grape seed oil for the same time. Overall groups (2-4), male chicken number became 30 used for 40.60 days at 7 hours per day. The schedule of work was achieved at 5 Gy/h of radiation equivalent dose with different exposure time for (20 and 40,60 days) on male chicken and at period 7 hours daily. The grape seed extract was bought from local market in Mosul City and filters from impure, as we found significant decrease in ratio of blood factors RBCs, WBCs, Hb and PCV with increasing of exposure time. This data changes with adding antioxidant materials as (grape seed oil) were the value of blood factors ratio enhancement by increasing the time of dose of these material compared with control group. The blood factors ratio of male chickens change with exposure time, with significant decrease by increasing exposure time, however, the protective material ( grape seed oil ) reduces the change in ratio % of the some blood factors compared with control group.

“…Research has shown that the effects of low-dose radiation on cells and tissues are different from those of high-dose radiation [ 6 ]. These effects probably include cell proliferation, chromosomal aberrations, cell-cycle disturbance, DNA damage, cell death and point mutations [ 7 , 8 ]. Currently, the radiation protection of risk assessment assumes that compared with high-dose exposures, the same level per unit absorbed dose or effective dose is caused by low-dose and low-dose-rate exposures [ 9 ].…”

The biological effects of low-dose or low-dose-rate ionizing radiation on normal tissues has attracted attention. Based on previous research, we observed the morphology of liver tissues of C57BL/6J mice that received <50, 50–500, and 500–1000 μGy/h of 137Cs radiation for 180 d. We found that the pathological changes in liver tissues were more obvious as the irradiation dose rates increased. Additionally, differential protein expression in liver tissues was analyzed using a proteomics approach. Compared with the matched group in the 2D gel analysis of the irradiated groups, 69 proteins had ≥ 1.5-fold changes in expression. Twenty-three proteins were selected based on ≥2.5-fold change in expression, and 22 of them were meaningful for bioinformatics and protein fingerprinting analysis. These molecules were relevant to cytoskeleton processes, cell metabolism, biological defense, mitochondrial damage, detoxification and tumorigenesis. The results from real-time PCR and western blot (WB) analyses showed that calreticulin (CRT) was up-regulated in the irradiated groups, which indicates that CRT may be relevant to stress reactions when mouse livers are exposed to low-dose irradiation and that low-dose-rate ionizing radiation may pose a cancer risk. The CRT protein can be a potential candidate for low-dose or low-dose-rate ionizing radiation early-warning biomarkers. However, the underlying mechanism requires further investigation.

“…There is a variety of published data on the effects of radioactive radiation, some of which are contradictory. For example, some researchers believed that low doses of radiation have a positive stimulating effect and lead to a radiation hormesis (Buldakov & Kalistratova 2005;Luan et al 2006;Monfared et al 2006;Luckey 2007;NAIR 2009;Nomura et al 2013;Gapeyev et al 2015;Hekim et al 2015;Vivek Kumar et al 2015;Cho et al 2016) Other studies denied any stimulating effects of any radiation dose and are convinced in the pathological reaction of the organism to radiation effects (El-Halim et al 2015;Ivanov et al 2015;Miñana et al 2015;Oujifard et al 2015). However, it is commonly accepted that radiation doses cause different functional changes in the cells, and subsequently, at the organismal level through the changing of the immunological reactivity of animals.…”

The main aim of the current study is to differentiate and analyze types of ecosystems in Mala planina Mt. The investigation is based on the typology of the Working Group for Mapping and Assessment on Ecosystems and their Services (MAES), following Action 5 of the EU Biodiversity strategy requiring member states to map and assess the state of ecosystems and their services in their own territories. The provided methodological framework for mapping of ecosystems is for the continental scale of Europe and it is applied to the local scale of a Bulgarian mountain. The map of the ecosystems in Mala planina Mt based on the MAES typology is created on the basis of information from CORINE Land Cover 2012 dataset. All other ecosystem types of terrestrial category except wetlands, heathland and shrub are presented in a different areal pattern. Grassland, woodland and forest are the most widely distributed ecosystem types of level 2, while urban, cropland and sparsely vegetated areas are randomly distributed.
