Abstract
Inflammation has a major role in the pathophysiology of sickle cell disease, in fact when it is recurrent, it contributes more to the obstruction of blood vessels through several biochemical mechanisms by provoking vaso-occlusive crises. In order to mitigate these adverse effects in sickle cell patients, the analgesic and anti-inflammatory potentials of extracts of a combination of organs of three plants were evaluated in this study. The analgesic and anti- inflammatory activities of the aqueous (DZHm) and hydroethanolic (EZHm) extracts (200, 400 and 800 mg/kg) were evaluated in rats as models of acetic acid-induced torsion and Carrageenan-induced hind paw edema, using Diclofenac and Ibuprofen as reference molecules. Oral administration of ZHm extracts at doses of 200, 400 and 800 mg/kg produced anti-inflammatory and analgesic effects. These extracts significantly reduced edema and pain. These effects are time and dose dependent. In terms of analgesic effect, the dose of 800 mg/kg bw generated a high inhibition rate of 84.51% and 73.06% for DZHm and EZHm respectively, while the inhibition percentage of Ibuprofen was 78.3 ± 2.09 at the dose of 100 mg/kg bw. The anti-inflammatory effect was 60, 55% for DZHm, 56.08% for EZHm and 62.91% for Diclofenac at 10 mg/kg Pc. Diclofenac and Ibuprofen used for these two tests generated similar activities with ZHm extracts at the dose of 800 mg/kg Pc. The tested extracts (DZHm and EZHm) have analgesic and peripheral anti-inflammatory potentials justifying the use of this recipe in the traditional environment.
