Radio-frequency electromagnetic radiation (RF-EMR) represents one of the environmental factor that influence animal organism to stress. In this study we determined the oxidative stress parameters from rat liver, kidney and brain tissues that were exposed to chronic 1800 MHz RF-EMR. Our study was designed in 3 groups as 9 animals in each group. These are; control, sham and RF-EMR exposed group. The control group was not exposed to any procedure; sham group was housed in the same room under the same conditions with equal time period, except that the generator was turned off. RF-EMR exposed group was subjected to 1800 MHz RF-EMR emitted from the signal generator for 2 h per day for eight weeks. All animals that completed the experimental period were sacrificed and liver, kidney and brain tissues of all rats were isolated for analyzing malondialdehyde (MDA), nitric oxide (NO) and reduced glutathione (GSH) levels and superoxide dismutase (SOD) and catalase activities. Liver, kidney and brain MDA and NO levels were higher and GSH level and SOD and catalase activities were significantly lower in RF-exposed group than control and sham groups (p<0.001). No significant difference was observed in terms of tissue MDA, GSH and NO levels and SOD and catalase activities between control and sham groups in each tissue. The results of our study shows that RF-EMR may act as an environmental stressor and cause oxidative and nitrosative damage in liver, kidney and brain tissues. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi.

Case Series: 11 Cases of Hemolytic Disease of the Fetus and Newborn Due To Kell Blood Group Incompatibility
(Yuzuncu Yil Universitesi Tip Fakultesi, 2024) Yürektürk, E.; Aycan, N.; Başaranoğlu, M.; Arslan, B.; Tuncer, O.
Hemolytic disease of the fetus and newborn (HDFN) results from the destruction of the newborn's red blood cells or the fetus by the mother's immune globulin G antibodies. Although HDFN is often caused by RhD and ABO incompatibility, it can also be seen due to minor blood groups such as Kell, Kidd, Duffy, P, MNS, or Rh subgroup (C, c, E, e) alloantibodies. Our study aims to share our experiences regarding a rare cause of HDFN. The files of patients who were followed up with the diagnosis of jaundice in a third-level Neonatology Unit of a university hospital between January 2014 and September 2023 were retrospectively examined. Eleven patients with Kell incompatibility were included in the study. There was no ABO/RhD incompatibility in any case. RhD subgroup incompatibility and Kell incompatibility were present in four cases. Phototherapy was applied to all patients. The patient, whose total bilirubin level was high despite phototherapy, was treated with an exchange transfusion. No complications were observed due to treatment or high total bilirubin. No significant difference was observed between the parameters evaluated according to the gender variable. It should be kept in mind that severe hemolysis and related deaths may occur due to Kell incompatibility. In order to reduce and prevent severe hemolysis due to Kell and other minor blood groups in newborns, transfusing blood products suitable for minor blood groups to women of childbearing age (especially pregnant women) may be a correct approach as a country policy. © 2024, Yuzuncu Yil Universitesi Tip Fakultesi.
