Neurotransmitters Level in Hypothyroid Male Albino Rats after Isotretinoin Treatment

Rehab F. El-Anwar, Lobna F. Wahman and S.T. Melek

Abstract:
Isotretinoin is the most effective anti-acne treatment but to some extent it has side effects. So, the aim of the present study was focused on the combined effect of isotretinoin treatment and hypothyroidism on cerebral monoamines in male albino rats. The animals were divided into four groups; control, hypothyroid, hypothyroid treated with isotretinoin and isotretinoin only treated. Hypothyroidism was induced by using 5 mg kg–1 propylthiouracil for 30 days. Oral isotretinoin was given in olive oil 1.5 mg kg–1 b.wt. equivalent to human therapeutic dose for 4 weeks. The withdrawal period is 2 weeks after drug stoppage. The concentration of epinephrine, nor epinephrine, dopamine and serotonin were estimated in different brain areas. Also, the serum level of free triiodothyronine and free thyroxin and thyroid stimulating hormone were measured to insure the hypothyroid state. Total body weight was recorded throughout the experimental period. Hypothyroid rat’s model exhibited a decrease of norepinephrine, dopamine and serotonin contents in most of the brain areas examined. Hypothyroid rats treated with isotretinoin exhibited elevated levels of neurotransmitter in most brain areas. isotretinoin treatment does not aggravate the monoamines dysfunction in hypothyroid rats.
