ABSTRACT

Opuntia ficus indica and Pistacia lentiscus L. seeds are used in traditional medicine. The objective of this study was to investigate the toxicity of the fixed oil of Opuntia ficus indica and Pistacia lentiscus L. seeds in mice through determination of LD50 values, and also the physicochemical characteristics of the fixed oil of these oils. The acute toxicity of their fixed oil were also investigated in mice using the method of Kabba and Berhens. The fixed oil of Pistacia lentiscus and Opuntia ficus indica seeds were extracted and analyzed for its chemical and physical properties such as acid value, free fatty acid percentage (% FFA), iodine index, and saponification value as well as refractive index and density. LD50 values obtained by single doses, orally and intraperitoneally administered in mice, were respectively 43 ± 0,8 ;[40.7- 45.4 ] ml/kg body wt. p.o. and 2.72 ± 0,1 ;[2.52-2.92] ml/kg body wt. i.p. for Opuntia ficus indica ; and 37 ± 1 ;[34.4 - 39.8 ] ml/kg body wt. p.o. and 2.52 ± 0,2 ;[2.22 - 2.81 ] ml/kg body wt. i.p. for Pistacia lentiscus respectively. The yields of seed oil were respectively calculated as 20.25% and 10.41%. The acid and free fatty acid values indicated that the oil has a low acidity.

ABSTRACT

Pistacia lentiscus fatty oil (PLFO) is a well known natural remedy in eastern Algeria folk medicine. It is widely used in the treatment of respiratory disorders and dermal burns. The present study has been carried out to investigate effects of this oil on fasting glucose and some functional parameters of the liver and kidney in white male New Zealand rabbits (Initial mean weight 1.95 Kg). PLFO was applied to tested rabbits (PLFO group) via rectal route, once daily 5-day per week, for six consecutive weeks at the dose of 1 ml/Kg body weight. The same number of animals (n=6) was not treated and served as control (CRL group). The results showed that PLFO was tolerated by rectal route. No significant differences were observed in body weights of the two groups. Biochemical analysis showed that aspartate transaminase (AST) and alanine transaminase (ALT) were significantly decreased in blood plasma at (P< 0.05) and (P< 0.01) respectively in PLFO group (Mann-Whitney test). On the other hand, the fasting glucose level (GLU) was significantly increased (Mann-Whitney test, P< 0.05), while the rest of the tested parameters (Albumin, total proteins, creatinine, urea) was not significantly affected. However, these variations have not biologic signification toxicity. The study concludes that PLFO is tolerable via rectal route; it is safe with no adverse effect on liver functions and renal functions with possible anti-glycogenesis activity.

ABSTRACT

This study aimed to assess the efficiency of the virgin fatty oil of Pistacia lentiscus (PLVFO) for burn wounds healing. It was carried out on 6 adult male New Zealand rabbits. Four burn wounds of deep third degree were made on the back of each animal. The first was not treated and served as control (CRL group); the others were covered immediately after burning procedure by 0.5g of one of the following products: Vaseline gel (VAS group), Madecassol(®) cream 1% (MAD group) or 1ml of PLVFO (PLVFO group). The treatments were repeated once daily until complete healing. For four days post burns, the percentage of wound contraction was assessed. Also, the different healing times were noted. The results showed that both PLVFO and Madecassol(®) significantly accelerated wound healing activity compared to wounds dressed with Vaseline and the untreated wounds. However, the level of wound contraction was significantly higher and the healing time was faster in PLVFO group than those of the MAD group, VAS group and CRL group. The different epithelization periods obtained in days were respectively: 30±3.94 (PLVFO group), 33.5±3.78 (MAD group), 34.66±3.88 (VAS group) and 37.16±3.54 (CRL group). We conclude that Pistacia lentiscus virgin fatty oil promotes significantly (p< 0.05) wound contraction and reduces epithelization period in rabbit model.
