RESUMEN

Currently, the use of alternative medicine is necessary, even in animals. Our study focused on the valorisation of the use of herbal products in Algerian veterinary medicine. This study is based on a 6-month exploratory survey of 257 private practicing veterinarians, followed by a study of the bacteriological activity of the essential oil of the Pistacia lentiscus plant. The survey results generally indicate that private veterinarians support phytotherapy as an alternative to conventional drugs in several areas and species. Also, the results of research conducted on the antibacterial activity of Pistacia lentiscusessential oil show that it inactivates 50% of the bacterial strains. This confirms the well-defined role of this medicinal plant used as an alternative in veterinary medicine.(AU)

RESUMEN

In order to evaluate the potential of this formulation (P. lentiscus L. oil-based ointment) to heal wounds, experimental wounds were done on guinea pigs and efficiency was comparatively assessed against a reference ointment, Cicaderma®. Wound contraction was performed on days 5, 10 and 15. Tissue sections were also evaluated histopathological on days 7, 14 and 21. Results showed that for all days (5, 10 and 15), the highest wound contraction values were attained for the P. lentiscus oil-based ointment treated group with wound contraction values of 19.38, 55.8 and 77.11%, respectively, as compared to the reference drug Cicaderma® where contractions were 7.97%, 49.53% and 71.44%, respectively. Vehicle and negative control groups however showed no statistically significant wound healing activity on the excision wound model. These experimental studies revealed that the P. lentiscus oil-based ointment displays remarkable wound healing activity, in accordance with its use in traditional medicine.

Con el fin de evaluar el potencial de esta formulación (ungüento a base de aceite de P. lentiscus L.) para curar heridas, se realizaron heridas experimentales en cobayos y se evaluó comparativamente su eficacia respecto de un ungüento de referencia, Cicaderma®. La contracción de la herida se realizó los días 5, 10 y 15. Las secciones de tejido también se evaluaron histopatológicamente los días 7, 14 y 21. Los resultados mostraron que para todos los días (5, 10 y 15), se obtuvieron los valores más altos de contracción de la herida para el grupo tratado con ungüento a base de aceite de P. lentiscus con valores de contracción de la herida de 19.38, 55.8 y 77.11%, respectivamente, en comparación con el medicamento de referencia Cicaderma® en donde las contracciones fueron 7.97%, 49.53% y 71.44%, respectivamente. Sin embargo, los grupos de control de vehículo y negativo no mostraron actividad de curación de heridas estadísticamente significativa en el modelo de herida por escisión. Estos estudios experimentales revelaron que la pomada a base de aceite de P. lentiscus muestra una notable actividad de curación de heridas, de acuerdo con su uso en la medicina tradicional.

RESUMEN

Abstract Plants are a large source of new bioactive molecules with therapeutic potentials. However, only a small amount of worldwide plants have been phytochemically investigated. The aqueous and ethanolic extracts of Pistacia lentiscus L., Anacardiaceae, leaves were evaluated for hypocholesterolemic activity in vivo. In this study, hypercholesterolemia was induced in animals by feeding them high cholesterol (1%) food. The extracts of P. lentiscus were orally administered at a dose of 200 mg/kg body weight along with a high cholesterol diet for thirty successive days. Lipid parameters such as total cholesterol, triacylglyceride, low density lipoprotein, very low density lipoprotein and high density lipoprotein were measured in the plasma. Total phenol and flavonoid contents were also evaluated. Flavonoid content was found to be more present in the ethanolic extract (8.218 ± 0.009 mg of QE/g) compared to the aqueous extract (3.107 ± 0.014 mg of QE/g). The administration of P. lentiscus extracts produced a significant decrease in total cholesterol, triacylglyceride and low density lipoprotein-cholesterol (154.6 ± 18.10, 71.2 ± 4.38 and 99.36 ± 18.77 mg/dl respectively) in the ethanolic extract, while the aqueous extract showed a significant decrease in total cholesterol and triacylglyceride (203.6 ± 9.18 and 97.6 ± 3.57 mg/dl respectively). The results of the investigation demonstrated that P. lentiscus leaf extract has hypocholesterolemic properties and might be used for the prevention of hypercholesterolemia associated disorders.
