Investigators in this study sought to explore whether MTX-induced dysfunction in the fallopian tubes would be lessened by the addition of FA to MTX treatment. For this study, 18 albino Wistar rats were randomly divided into 6 groups, each of which comprised 3 rats; 0.1 mg/kg FA, 1 mg/kg MTX + 0.1 mg/kg FA, 5 mg/kg MTX + 0.1 mg/kg FA, 1 mg/kg MTX, and 5 mg/kg MTX were given to groups 2, 3, 4, 5,and 6, respectively; group 1 was the control group. After MTX injection, fallop-ian tube samples from all groups were prepared for examination under electron microscopy. The findings observed in groups 1 and 2 were similar. The level of cellular destruction was greater with the higher doses of MTX without FA; in particular, loss of cilia in the epithelium was prominent in groups 5 and 6. However, there was less cellular destruction observed in groups 3 and 4 than in groups 5 and 6. As a result, the addition of FA should not be overlooked, even when a single-dose MTX regimen is chosen for the treatment of patients with unruptured ectopic pregnancy. | lld:pubmed |
