Experimental study comparing burn healing effects of raw South African Shea butter and the samples from a Libyan market

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

Study of caffeine consumption rate and concentration in different food and beverages consumed by children

Caffeine has dose-dependent effects on mood, attention, and physiology. Behavioral effects of caffeine in humans have also been well documented. This article aimed to study the effect of different caffeine concentrations on behavior and motor activity of mice. The experiments was carried out using 24 male mice (25-30gm). Plus maze was used for screening of antianxiety effect of caffeine. While swimming maze was used to test antidepressant effect. Statistical analysis were performed using computer program SPSS (version 22). At dose of 100 mg/kg, caffeine acted as anxiolytic compound. Caffeine increased motor activity at dose of 25mg/kg and decreased motor activity at dose of 200mg/kg. At dose of 100mg/kg, caffeine acted as antidepressant. In conclusion, caffeine can act as stimulant, while in over dose it acts as depressant. Caffeine showed to have anxiolytic effect in certain doses. arabic 14 English 91

Study of Caffeine Consumption Rate and Concentration in Different Food and Beverages Consumed by Libyan Children

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
