Comparison of the Expression Levels of MBP and GFAP Following the Induction of Neuronal Demyelination with Ethidium Bromide in Male and Female Rats

MS is an autoimmune, inflammatory disease with demyelination and astrogliosis of the central nervous system that affects the brain and spinal cord. Its prevalence in women is three times that of men.

This study was conducted on 42 male and female rats with an approximate weight of 300-350 grams in Shahid Chamran Faculty of Veterinary Medicine, Ahvaz. Material: The male sham group (received normal saline), the female sham group (received normal saline), the male MS group and the female MS group were divided. In order to inject ethidium bromide in the MS groups using a microinjector, rats were Ketamine (80 mg/kg) and xylazine (5 mg/kg) were anesthetized, 0.02% ethidium bromide and 20microliter normal saline were injected using a Hamilton syringe.

The results of this study showed that the inflammation and degeneration of nerve cells increased in the MS groups, and this inflammation and degeneration was more in males, and the level of MBP expression in the MS group was reduced compared to other groups, which compared The two genders of this reduction in expression were almost the same, and the amount of GFAP expression in the MS group was increased compared to the other groups, which was higher in the female gender when comparing the two genders.

MS causes a decrease in the amount of myelin basic protein and an increase in the astrogliosis factor, which leads to the destruction of the myelin sheath and astrocytes and causes sensory and motor disabilities in people with MS.
