Pistacia lentiscusL. is known in some Tunisian forest area by its fixed oil used in traditional medicine as an antiseptic product. This investigation is the first to study the antimicrobial activity ofP.lentiscusedible oil and its phenolic extract. Oil was extracted from fruits harvested from six provenances located in Tunisia. The antimicrobial activity was tested using disc diffusion assay and the broth dilution method. Kbouch and Sidi Zid oils were most efficient (p < 0.003) against, respectively,Staphylococcus aureusandAspergillus nigerwith an inhibition zone of 9.33 mm. The phenolic extract had the largest spectrum of sensitive microorganisms. The minimum inhibitory concentration and minimum bactericidal concentration results showed that all strains were inhibited by both oil and extract. [ABSTRACT FROM PUBLISHER]

In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content ofPistacia lentiscusfixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest α-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenting more than 50% of the total fatty acid content. Kebouche oil presented the highest oleic acid content (55.66%). All these results highlight the richness of carotenoids, tocopherols and unsaturated fatty acids inP. lentiscusseed oil and underscore the nutritional value of this natural product.

The skin is a rare site of metastasis of the internal malignancies. On the contrary, lung cancer is a common primary malignancy of skin metastasis. The latter is either synchronous with the primary lung tumour or can reveal it. To analyse the clinical findings and the outcome of cutaneous metastasis in patients with primary lung cancer. Retrospective study including 12 cases of cutaneous metastasis of lung cancer diagnosed in our institution during 6 years. Our patients included three women and nine men with a median age of 59.83 years. The cutaneous metastases were unique in seven cases. They revealed the primary tumour in two cases, were discovered synchronously with the primary tumour in six cases and after the primary tumour in four cases. They appeared in patients presenting multiple metastases in 10 cases. Clinical appearance consisted on a firm nodule, sometimes ulcerated with a diameter ranging from 0.5 to 5.5 cm. The tumour was sited in the thorax, the back, the abdomen; or the upper or lower limbs. Pathological examination of bronchial biopsy revealed an adenocarcinoma in eight cases, a squamous cell carcinoma in two cases and a small cell carcinoma in two cases. In spite of lung cancer therapies, the patients with metastasis to other organs with a median follow-up time of 4 months died. Cutaneous metastases of lung cancer are of poor prognosis. They are most of the time associated with an advanced neoplastic process with metastasis to other organs. Median survival after skin involvement does not exceed months. [ABSTRACT FROM AUTHOR]
