عنوان انگلیسی Related Fluoxetine and Methylprednisolone Changes of TNF-α and IL-6 Expression in The Hypothyroidism Rat Model of Spinal Cord Injury
چکیده انگلیسی مقاله Objective
Spinal cord injury (SCI) is a serious clinical condition that leads to disability. Following primary injury, pro- inflammatory cytokines play an important role in the subsequent secondary events. The thyroid hormone (TH) is known as the modulator of inflammatory cytokines and acts as a neuroprotective agent. Methylprednisolone (MP) is used for the early treatment of SCI. Fluoxetine (FLX), also is known as a selective serotonin reuptake inhibitor (SSRI), has therapeutic potential in neurological disorders. The aim of the present study was to investigate the combined effects of MP and FLX on SCI in the rat hypothyroidism (hypo) model.
Materials and Methods
In this experimental study, 48 male Wistar rats with hypothyroidism were randomly divided into 6 groups (n=8/group): control (Hypo), Hypo+Surgical sham, Hypo+SCI, Hypo+SCI+MP, Hypo+SCI+FLX, and Hypo+SCI+MP+FLX. SCI was created using an aneurysm clip and Hypothyroidism was induced by 6-Propyl-2-thiouracil (PTU) at a dose of 10 mg/kg/day administered intraperitoneally. Following SCI induction, rats received MP and FLX treatments via separate intraperitoneal injections at a dose of 30 and 10 mg/kg/day respectively on the surgery day and FLX continued daily for 3 weeks. The expression levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were quantified by Real-time polymerase chain reaction (PCR) and Western blotting. Myelination and glutathione (GSH) levels were analyzed by Luxol Fast Blue (LFB) staining and ELISA respectively.
Results
Following combined MP and FLX treatments, the expression levels of TNF-α and IL-6 significantly decreased and GSH level considerably increased in the trial animals.
Conclusion
Our results show the neuroprotective effects of MP and FLX with better results in Hypo+SCI+MP+FLX group. Further study is required to identify the mechanisms involved.
