Abstract

Methimazole, a widely used agent in the treatment of hyperthyroidism, is also used to induce hypothyroidism in experimental studies. In this study, we aimed to evaluate cognitive functions and anxiety- and depression-like behaviours in a methimazole-induced rat hypothyroidism model. Twelve adult female/male Wistar rats (250-300 g) were randomly divided into two groups, one of which was given 0.02% methimazole in drinking water for 4 weeks, as the other group was given normal water. After 4 weeks, Morris water maze, elevated plus maze, tail suspension test, passive avoidance test was applied. Serum free T4 and TSH levels were measured 8 weeks after discontinuation of methimazole, and thyroid tissue was evaluated histopathologically. In the Morris water maze test, a significant difference was observed between the groups only on the 1st day (p

Özet

Hipertiroidizm tedavisinde yaygın olarak kullanılan metimazol, deneysel çalışmalarda geçici hipotiroidizm modeli oluşturmak için kullanılmaktadır. Çalışmamızda metimazol ile oluşturulan sıçan hipotiroidi modelinde kognitif fonksiyonların değerlendirilmesi ve hipotiroidinin anksiyete ve depresyon benzeri davranışlar üzerine etkisinin belirlenmesi amaçlanmıştır. Oniki adet erişkin dişi/erkek Wistar sıçan (250-300 g) iki gruba ayrılarak bir gruba 4 hafta süre ile içme suyu içinde %0,02 metimazol verilerek hipotiroidizm oluşturulmuş, diğer gruba normal içme suyu verilmiştir. Dört hafta sonunda, Morris su labirenti, yükseltilmiş artı labirent, kuyruk suspansiyon testi, pasif sakınma testi uygulanmıştır. Metimazol kesildikten 8 hafta sonra serum serbest T4 ve TSH düzeyleri ölçülmüş ve tiroid dokusu histopatolojik olarak değerlendirilmiştir. Morris su labirenti testinde sadece 1. günde gruplar arasında anlamlı fark izlenmiştir (p
