Background: The fat extracted from the nut of the African Shea tree (Vitellaria paradoxa) is called Shea butter. It has multiple uses at the local level as it is used in cosmetic products and as a cocoa butter substitute in chocolate industries. It has a high nutritious value and is also a valuable product on the local, national, and international markets, making it the ideal candidate to research and invest in. Aim: This study is a comparative experimental study of the possible burn healing effects between imported South African raw Shea butter and samples in a Libyan market. Method: The control samples were brought from South Africa (Benin traditional markets). A total of 18 different samples were collected from different sale centers in Tripoli, including pharmacies, beauty shops, and spices shops, in addition to one sample brought from Poland. Animal experiment on burn healing effect was carried out on nine male Sprague Dawley (350–400 g) rats aged 6–8 weeks old. After shaving the animal’s dorsum hair, a metal cube was used to create a deep second degree burn wound, and the cube was heated to 100°C for 20 seconds. Medication with Shea butter (control, T1, and T2) was initiated daily for one for these groups by the application of a thin film of the Shea butter samples on the burned areas. On days 1, 3, and 7, the rats were anesthetised and a sample from the burned scar tissue and skin adjacent were evaluated using pathological parameters. Results: The histological study indicates that the use of Shea butter T1 as topical treatment induces an immune response, which enhances the form of the presence of a large number of inflammatory cells in the epidermis and dermis layers. The treatment of burned skin with T2 lasted for 72 hours and it showed slightly significant healing in the normal structure of proliferative granulation tissue with accumulation of fibroblasts and inflammatory cells surrounding the sebaceous glands and hair follicles. Small areas of the epidermis which formed few layers were observed and some hair roots were grown. This was well seen in cases of T1 and T2. Shea butter bought as raw might have a bad effect on burned skin. Conclusion: Shea butter bought as raw might have bad effect on burned skin. On the other hand, the sample from Poland had a therapeutic effect, which was because of the additives such as avocado oil, grape seed oil, and others. arabic 18 English 101

Introduction: Smoking is a major avoidable cardiovascular risk factor and is a cause of premature death worldwide. Objectives: To study the prevalence, pattern, and awareness of health hazards of smoking among Libyan diabetic male patients in Tripoli Medical Center, Tripoli, Libya. Patients and Methods: A cross-sectional, clinic-based study using a predesigned questionnaire, the participants were interviewed by the author. The interview covered personal data, and questions about their smoking status, and their awareness of smoking hazards. Results: The overall prevalence of current smoking was 26.4% and past smoking 40.3%. The mean age was 50.8 ± 14.4 years (range 18–75 years). The mean age at which smoking started was 18.6 ± 5.3 years; all current smokers were cigarette smokers. Main reason for quitting smoking was related to health issues while social and religious considerations were the main reasons for never smoking. Conclusions: The prevalence of smoking among Libyan diabetic patients was high; this calls for incorporating smoking cessation services within the diabetes care clinics

Mutations in the TAL1 (T-cell acute leukemia 1) gene were recently described in patients with T-cell acute lymphoblastic leukaemia (T-ALL) and in those with lymphoblastic T-cell non-Hodgkin’s lymphoma (T-NHL). The purpose of this pilot study was to assess the prevalence of mutations in TAL1 gene in T-ALL and TNHL. DNA samples from 15 unrelated healthy controls, 20 T-ALL patients, and 10 T-NHL patients were analyzed using DNA-PCR and direct DNA sequencing to identify sequence genetic variations in TAL1 gene (exons 2 and 3). TAL1 exon 2 mutations were identified in 7.7% adult and 12.5% adolescent T-ALL patients analyzed. TAL1 exon 2 mutations were detected in 16.7% of the adult TNHL patients analyzed. Sequencing of TAL1 exon 3 showed no sequence variation for the T-ALL and T-NHL cancer patients analyzed. No sex difference where observed in the incidences of TAL1 exons 2 mutations between T-ALL and T-NHL patients with and without TAL1 mutations. TAL1 exon 2 missense and frame-shift mutations were present in 44.4% (4/9) and 55.6% (5/9) of T-ALL patients, respectively. However, the frame-shift and missense mutations in the T-NHL patients accounted for, where respectively, 60% (3/5) and 40% (4/5) of all TAL1 exon 2 mutations. Comparing the clinical features showed that there are no differences in PLT and WBC counts as well as the average age between T-ALL and T-NHL patients with and without TAL1 mutations. Overall, these findings indicate that TAL1 mutations are too rare to be of clinical relevance, and do not seem to be significantly associated with the increased T-ALL and T-NHL susceptibility, implying different pathways with respect to TAL1 genetic polymorphisms as a risk factor for T-ALL and T-NHL at least in this population of Libyans.
