Description: Background. The risks to human health have grown over the past ten years due to excessive use of mobile phones. The study determined the deleterious effects of 4G mobile phone radiations on the expression of the immunogenic and vascular genes as well as gross, microscopic and biochemical alterations in the development of chicken embryos. Methods. Mobile phones (SAR 1.4 W/kg, 2100MHz) were placed near the exposure group (n=60) in the incubator within 12 cm. The total exposure time of video calling was 60 minutes per night for 14 days. For histopathological examination, hematoxylin and eosin (H & E) staining was done. Cresyl violet staining was performed for measuring the numbers and evaluates the normal and abnormal neurons of brain. The biochemical parameters of amniotic fluid were analyzed using photometry method. The vascular gene (VEGF-A) and immunity genes (AvBD9, IL6) expression were done by real-time PCR (qPCR) technique. Results. In comparison to the control, the exposure group's body weight and length significantly decreased (p<0.05). Subcutaneous bleeding was seen in exposure group. Urea, creatinine, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT) levels were all significantly higher than in the control group (p< 0.05). In microscopic examination of liver of exposed group found some pathological lesions. In cerebral cortex found degenerated neurons with lightly stained nuclei in exposed group. The number of hyperchromatic neurons in exposure group (58.8± 2.39) was significantly higher (P < 0.05) than control (6.6± 0.55). The quantity of lymphocytes in exposed group (86.8±6.09) per slide was reduced compared to control (147.2± 11.23) (P < 0.05). Vascular gene mRNA expression was higher in the exposed group compared to the control group, but immune gene expression was lower. Conclusion. Gross, microscopic and biochemical alteration and gene expression might lead to hampering embryonic development due to mobile phone radiation exposure

Description: Monosodium glutamate (MSG) commonly used as a flavoring agent (E621) to increase the flavor of food, canned vegetables, soups and processed meats etc.Fertile chicken eggs (Sonali cross-breed) with the average egg weight of 53gm were injected with 0.1 ml of the MSG solution (0.75mg MSG/gm. egg weight and 1.0mg MSG/gm. egg weight) in the air cavity before incubation.Control group was injected with 0.1 ml of distilled water. A total of 300 eggs were divided into three groups. Each group was containing 100 eggs. Embryos were extracted on day 7, 10, 14 and 18 of incubation, twentyfive for each group.A significant decrease was seen for whole body weight, whole body length and beak length of day 7, 10, 14 and 18 day treated embryos compared to the controls except neck length. The p-value is < .00001 at 5% level of significance. Abdominal hernia, delay in growth, subcutaneous bleeding, brain and beak deformities were seen in several treated embryos of day 10, 14 and 18. The number of abdominal hernia and subcutaneous bleeding were seen more in treated group B than the treated group A.Histological cross sections of liver of 18 day treated with MSG chicken embryos showed less density of hepatocyte. Hemorrhages were found in central vein and sinusoids. Several empty areas were seen in the peripheral parts of the liver. The nucleus of treated groups embryos were shrinkage. Phagocytic cells were also found in various blood sinusoids.The histopathological observations of kidney of day 18 treated with MSG chicken embryos showed that various cytoplasmic vacuolation, degeneration of tubules, cellular swelling, karyorrhexis and pyknotic of cells. It was concluded thatthe effects of MSG on liver and kidney of chicken embryo, express that there are significant histo-pathological changes occurred in the liver and kidney tissues.
