Interleukin (IL) 6 and 18 plays an important role in inflammatory response following hypoxia ischemia encephalopathy (HIE). Present study was designed to demonstrate the effect of two GABAB receptor antagonists (CGP 35348 and 55845), respectively, on the serum IL6 and IL 18 concentrations in albino mice. Albino mice pups (of both genders) were subjected to Murine model of hypoxia-ischemia encephalopathy on postnatal day 10 (right common carotid artery was ligated followed by 8% hypoxia for 25 minutes). After neonatal brain damage and following weaning, mice were divided in three groups, in gender specific manner, and fed on normal rodent diet till they were 13 week old. At this time point, group 1 received intraperitonial saline solution (control group), group 2 was supplemented with CGP 35348 (1mg/ml solvent/Kg body weight) and group 3 with CGP 55845 (1mg/ml solvent/Kg body weight), intraperitonially, for 12 days and IL 6 and 18 concentrations were determined in serum by ELISA. It was observed that CGP 35348 supplementation resulted in reduced interlukin-6 and interlukin-18 concentrations in male albino mice. While CGP 55845 supplementation increased IL-6 and IL-18 concentrations in female albino mice following HIE. Our results are indicating that GABAB receptor antagonist's supplementation affects IL concentrations in albino mice in a gender specific manner following neonatal brain damage and can be further explored for the treatments of hypoxia ischemia associated neurological ailments.
