Effects of Telfairia occidentalis (Hook F.) Methanol Leaf Extract on the Haematological Indices and Histomorphology of the Endometrium and Liver of Female Albino Rats
The objective of this study was to evaluate the effects of administration of Telfairia occidentalis (Hook f.) methanol leaf extract on some hematological indices and histomorphology of the uterus and liver of female albino rats. Acute toxicity study of the extract was performed with female rats, following standard procedure. They were randomly assigned into 3 groups. The first group (A) served as the untreated control and received distilled water, while the second group (B) and third (C) received 200 and 800 mg/kg mg/kg body weight of the methanol leaf extract of T. occidentalis respectively. Administration of the extract was done daily via the oral route for 21 days. Blood was collected for hematological evaluation at weekly intervals. Hematological parameters assessed were the packed cell volume (PCV), red blood cell (RBC) count, hemoglobin concentration (HB) and total white blood cell (TWBC) count. At the end of the study period uterine and liver tissues were excised and prepared for histological examination. Results showed that there was a significant decrease (P < 0.05) in the mean PCV, RBC and HB values of the treatment groups, but only at the end of the second week of administration of the extract. There was no significant difference (P > 0.05) in the mean total WBC throughout the duration of the study. Histological examination of uterine and liver tissues of the different groups did not show any lesions. It was concluded that the T. occidentalis leaf methanolic extract does not adversely affect the reproductive functions of the uterus.
