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

Caffeine is the most commonly used psychoactive substance throughout the world. It is found in coffee, black tea, and chocolate, as it is produced naturally in the beans and leaves of the plants used to manufacture these products. This study aimed to make a survey study among children 2-11 years in some Tripoli, Libya schools to determine caffeine concentration in number of beverages and foods consumed by studied children. About 313 copies of the questionnaire were distributed to students to be filled by their parents. Caffeine was extracted from samples using dichloromethane. Purity of isolated caffeine was estimated by using TLC method.Quantitative analysis of caffeine was performed by using a UV-Visible spectrophotometer. Chocolate biscuits, chocolate cake, cocoa milk and chocolate ice cream were the highest consumed products among the studied children (81%, 79%, 67% and 63% respectively). The highest side effects of caffeine consumption was hyperactivity was the highest side effect in children (76%). Some children also suffered from severe side effects such as panic attack (14%). Naseem ice cream sample showed the highest caffeine content (28 mg/serving) among solid samples.Whereas in the beverages, energy drink samples Red pull, XIR and Shark were 268, 262 and 250 mg/serving respectively. In conclusion, there was excessive consumption of caffeine among the studied group of children and some of them showed side effects and even severe side effects. Variety of tested foods and beverages under the study contained uncontrolled concentrations of caffeine. In addition, chocolate milk (Al Rayhan), contained no caffeine. arabic 15 English 97

قرحة المعدة والإثناعشر هي من أكثر أمراض الجهاز الهضمي انتشارا وتنتج عن تلف الغشاء المخاطي للمعدة والإثناعشر نتيجة لعدة عوامل أهمها: زيادة إفراز حمض الهيدروكلوريك والعدوى بميكروب الحلائز البوابية والاستخدام المزمن للأدوية المضادة للالتهابات الغيرستيرويدية، إضافة إلى عوامل أخرى مثل التدخين والاستعمال المفرط للكحول. كما تلعب العوامل النفسية والإجهاد العصبي دوراً هاماً في استحداث المرض. أثبتت العديد من الدراسات السابقة على فئران التجارب أن الأدوية المضادة للاكتئاب والتوتر تساعد في تخيف أعراض قرحة المعدة والتي تزيد نسبة الإصابة بها في مرضي الحالات العصبية والنفسية مثل القلق واضطرابات الشخصية والاكتئاب. الهدف من الدراسة: يعتبر الدواء مرتازابين من الأدوية الحديثة لعلاج مرض الاكتئاب، هذا الدواء له آلية تأثير مميزة، عليه صممت هذه الدراسة لدراسة التأثير المضاد للمرتازبين على القرحة المعدية المستحدثة في الفئران البيضاء بواسطة الإيثانول. الخطوات وطرق العلاج: ثم استعمال فئران بيضاء بالغة من الذكور في جميع التجارب. تم إعطاء الإيثانول لكل الفئران عن طريق الفم بجرعة تساوي 1 ملي ليتر/200 جرام من وزن الجسم. ثلاث جرعات مختلفة من عقار المرتازابين (15،30،60 ملجم/كجم) تم إعطاؤها لمجموعات مختلفة من الفئران ساعة قبل تجريعها الإيثانول، وقورنت النتائج بمجموعة مرجعية عولجت بعقار الرانيتيدين 50 ملجم/كجم وهو مثبط لمستقبلات الهيستامين نوع-2. النتائج: بينت نتائج هذه الدراسة أن الجرعات المختلفة لعقار المرتازابين قللت وبشكل فعال من أعداد وأطوال قرحة المعدة الناجمة عن الإيثانول، وكانت الجرعة 30 ملجم/كجم هي الأكثر فعالية في التقليل من حدوث القرحة في الفئران. وأكدت التغيرات الهيستوباثولوجية لنسيج المعدة في المجموعات المختلفة تلك النتائج. إضافة إلى ذلك فإن المعالجة بعقار المرتازابين أدى إلى زيادة طفيفة في حموضة المعدة الكلية، وكانت الزيادة ملحوظة مع استعمال الجرعة العالية من المرتازابين وهي 60 ملجم/كجم. الاستنتاج: نستنج من هذه الدراسة أن المعالجة المسبقة للفئران بالعقار المضاد للاكتئاب المرتازابين قبل استحداث القرحة المعدية بالإيثانول يؤدي إلى التقليل من حدوث هذه القرحة، وهذه الحماية لا ترتبط بالتقليل من إفراز الحمض المعدي والذي كانت زيادته ملحوظة باستخدام الجرعات المختلفة من المرتازابين. Abstract: Despite the availability of many drugs used to treat peptic ulcer disease, the search for new therapy is continued. Antidepressant drugs are among the drugs used since the early 1950s to treat gastric ulcers. In this study the antiulcer activity of 15, 30 and 60 mg/kg of the antidepressant drug mirtazapine has been evaluated on ethanol-induced gastric ulcers in wistar rats. The results have been compared with those of a reference group treated with 50 mg/kg ranitidine and an ulcer control group given distilled water as a pre-treatment before administration of ethanol. All the three doses of mirtazapine have significantly reduced the number (p
