Objectives: This present study was to compare the serum electrolytes (Na, K and Cl) imbalances in hypothyroidism, hyperthyroidism with euthyroidism female cases. Methods: A detail history, clinical examinations and relevant investigations were performed to all female thyroid cases. Thyroid hormones were estimated by chemiluminiscence method using Siemens Advia Centaur XP instrument. Electrolyte levels (Na+, k+ & Cl-) were measured by ion selective electrode method using Eschweiler combi. Results: Data was analyzed with the help of SPSS (version 26) software. Paired samples statistics was used. Mean ± standard deviation and t value were calculated. P value was taken less than or equal to 0.05 (p ≤ 0.05) for significant differences. Conclusions: This present study concluded that electrolytes sodium, potassium and chloride levels were significantly reduced in hypothyroidism female cases compared to euthyroids female (controls). This suggests that hypothyroid patients should be regularly checked for serum electrolytes. Early detection and treatment can prevent the further complications related to the disorder and will be helpful during the management of thyroid patients. Key words: Hypothyroidism, hyperthyroidism, euthyroidism, electrolytes.

Background: Hypoxic-ischemic encephalopathy (HIE) is a major cause of pediatric and adult mortality and morbidity. Unfortunately, to date, no effective treatment has been identified. In the striatum, neuronal injury is analogous to the cellular mechanism of necrosis observed during NMethyl- D-Aspartate (NMDA) excitotoxicity. Adenosine acts as a neuromodulator in the central nervous system, the role of which relies mostly on controlling excitatory glutamatergic synapses. Objective: To examine the effect of pretreatment of SCH58261, an adenosine 2A (A2A) receptor antagonist and modulator of NMDA receptor function, following hypoxic-ischemia (HI) on sodium- potassium ATPase (Na+, K+-ATPase) activity and oxidative stress. Methods: Piglets (4-7 days old) were subjected to 30 min hypoxia and 7 min of airway occlusion producing asphyxic cardiac arrest. Groups were divided into four categories: HI samples were divided into HI-vehicle group (n = 5) and HI-A2A group (n = 5). Sham controls were divided into Sham vehicle (n = 5) and Sham A2A (n = 5) groups. Vehicle groups were pretreated with 0.9% saline, whereas A2A animals were pretreated with SCH58261 10 min prior to intervention. Striatum samples were collected 3 h post-arrest. Sodium-potassium ATPase (Na+, K+-ATPase) activity, malondialdehyde (MDA) + 4-hydroxyalkenals (4-HDA) and glutathione (GSH) levels were compared. Results: Pretreatment with SCH58261 significantly attenuated the decrease in Na+, K+-ATPase, decreased MDA+4-HDA levels and increased GSH in the HI-A2A group when compared to HIvehicle. Conclusion: A2A receptor activation may contribute to neuronal injury in newborn striatum after HI in association with decreased Na+, K+-ATPase activity and increased oxidative stress.
