چکیده

D-002, a mixture of six higher aliphatic alcohols purified from beeswax, has been shown to produce anti-inflammatory effects in experimental models, devoid of gastrotoxic or hepatotoxic effects. Some studies have demonstrated that D-002 exerts analgesic effects, but just related to its anti-inflammatory action. The objective of this study was to compare the effects of D-002, naproxen, aspirin and paracetamol on the acetic acid-induced writhing test in mice. Mice were allocated into 13 groups : a vehicle control group, four D-002 (25, 50, 200 and 400 mg/kg, respectively)-, three naproxen (10, 20 and 50 mg/kg)-, three aspirin (50,100 and 300 mg/kg) and two paracetamol (100 and 400 mg/kg)-treated groups by gastric gavage. One hour after treatment, mice were injected with 1 % acetic acid and the numbers of writhing movements were counted for 15 min. Oral treatment with D-002 (50, 200 and 400 mg/kg) significantly inhibited acetic acid-induced abdominal writhing (36, 43 and 40 % respectively). The number of wrights decreased significantly with aspirin 100 and 300 mg/kg (47 and 83 %); naproxen 20 and 50 mg/kg (37 % with both doses) and paracetamol 400 mg/kg (24 %). The lowest doses of each treatment failed to inhibit significantly the acetic acid-induced abdominal writhing. The effect of D-002 (400 mg/kg) was comparable to that of naproxen (20 and 50 mg/kg). Maximal effective doses of D-002 (200 mg/kg) and naproxen (20 mg/kg) were less effective than aspirin 300 mg/kg for inhibiting the acetic acid-induced abdominal writhing, meanwhile paracetamol 400 mg/kg was the least effective treatment. RESUMEN. D-002 es una mezcla de seis alcoholes alifáticos superiores purificados de la cera de abejas con efectos antiinflamatorios demostrados en modelos experimentales sin efectos gastrotóxicos o hepatotóxicos. Algunos estudios han demostrado el efecto analgésico del D-002 relacionado con su acción antiinflamatoria. El objetivo de este trabajo consistió en comparar el efecto del D-002, naproxeno, aspirina y paracetamol sobre el modelo de contorsiones inducidas por ácido acético en ratones . Los ratones fueron distribuidos en 13 grupos (10 animales/grupo):un control con vehículo, cuatro con D-002 (25, 50, 200 y 400 mg/kg), tres con naproxeno (10, 20 y 50 mg/kg) tres con aspirina (50, 100 y 300 mg/kg) y dos con paracetamol (100 y 400 mg/kg) por vía oral. Una hora después del tratamiento, los ratones fueron inyectados con ácido acético (1,0 %) y el número de contorsiones durante 15 min registrado. El tratamiento oral con D-002 (50, 200 y 400 mg/kg) inhibió significativamente las contorsiones abdominales (36, 43 y 40 %). El número de contorsiones disminuyó significativamente con 100 y 300 mg/kg de aspirina (47 y 83 %); naproxeno 20 y 50 mg/kg (37 % con ambas dosis) y paracetamol 400 mg/kg (24 %). La menor dosis de cada tratamiento no mostró efecto analgésico. El efecto del D-002 (400 mg/kg) fue comparable al naproxeno (20 and 50 mg/kg). La máxima dosis efectiva de D-002 (200 mg/kg) y naproxeno (20 mg/kg) fueron menos efectivas que la aspirina (300 mg/kg) en inhibir las contracciones por ácido acético, mientras que el paracetamol (400 mg/kg) resultó el tratamiento menos efectivo.
