Ameliorative Effect of Methanolic Extract of Orange Peels on Serum Thyroxine, Triiodothyronine and Haematological Parameters in Male Albino Wister Rats Following Mercury Toxicity
Abstract
This study investigated the ameliorative effect of methanolic extract of orange peel on serum
thyroxine (T4), triiodothyronine (T3) and haematological parameters in male Wister rats
following mercury toxicity. Fifteen (15) apparently healthy mature wistar strain albino rats
weighing 170g-180g, were housed in a standard rat cage and fed on standard feed. The
experimental rats were randomly divided into three groups of five rats each and allowed to
acclimatize before the commencement of the experiment. The groups were as follows; group I
(normal saline), group II (mercury chloride; 3.0 mg/kg alone) and group III (orange peel extract;
600mg/kg and mecury chloride; 3.0 mg/kg) in a completely randomized design. The treatment
was done for 21 consecutive days. Two (2) ml of blood was collected through the saphenous vein
once weekly for three weeks for determination of serum levels of thyroxine and triiodothyronine
and whole blood for haematological parameters. The result revealed significant (P≤0.05) decrease
in T4 and T3 in group II (25.3 ± 0.7 nmol/l; 0.9± 0.52 nmol/l) compared to group I (38± 0.23
nmol/l ; 1.9± 0.34 nmol/l) and a significant (P≤0.05) recovery for these parameters was observed
in group III (30.3± 1.2 nmol/l; 1.4 ± 0.55 nmol/l) compared to group II. Significant increase
(P≤0.05) was also observed on all haematological parameters in group I and group III, however
there was a significant decrease (P≤0.05) on all haematological parameters except for white
blood cell which increased significantly (P≤0.05) in group II. It was concluded that methanolic
orange peel extract ameliorated the toxic effect of mercury on thyroid hormones and
haematological parameters in male Wister rats.
