Item Effects of gum Arabic ingestion on body mass index and body fat percentage in healthy adult females: two-arm randomized, placebo controlled, double-blind trial(Nutrition Journal, 2012) Babiker,Rasha; Merghani,Tarig H; Elmusharaf,Khalifa; Badi,Rehab M; Lang,Florian; Saeed,Amal MBackground: Gum Arabic (acacia Senegal) is a complex polysaccharide indigestible to both humans and animals. It has been considered as a safe dietary fiber by the United States, Food and Drug Administration (FDA) since the 1970s. Although its effects were extensively studied in animals, there is paucity of data regarding its quantified use in humans. This study was conducted to determine effects of regular Gum Arabic (GA) ingestion on body mass index and body fat percentage among healthy adult females. Methods: A two-arm randomized, placebo controlled, double-blind trial was conducted in the Department of Physiology at the Khartoum University. A total of 120 healthy females completed the study. They were divided to two groups: A test group of 60 volunteers receiving GA (30 gm /day) for 6 weeks and a placebo group of 60 volunteers receiving pectin (1 gm/day) for the same period of time. Weight and height were measured before and after intervention using standardized height and weight scales. Skin fold thickness was measured using Harpenden Skin fold caliper. Fat percentage was calculated using Jackson and Pollock 7 caliper method and Siri equation. Results: Pre and post analysis among the study group showed significant reduction in BMI by 0.32 (95% CI: 0.17 to 0.47; P<0.0001) and body fat percentage by 2.18% (95% CI: 1.54 to 2.83; P<0.0001) following regular intake of 30 gm /day Gum Arabic for six weeks. Side effects caused by GA ingestion were experienced only in the first week. They included unfavorable viscous sensation in the mouth, early morning nausea, mild diarrhea and bloating abdomen. Conclusions: GA ingestion causes significant reduction in BMI and body fat percentage among healthy adult females. The effect could be exploited in the treatment of obesity.Item Characterization of symptomatic Knee Joint in Sudanese(Scholars Journal of Applied Medical Sciences, 2014) Mustafa,Badria Awad Elamin Mustafa; Garelnabi,MEM; Mohamed,Sharaf Elgizouly; Abdulrahim,Salah Mohamed; Osman,HKnee Joint is one of largest and complex joint in the human body. The aim of this study was to characterize symptomatic knee joints in Sudanese population by using height and circumference of knee joint to predict pathological changes that appear in the planner x-ray film in advance. A total of 257 symptomatic knee joints were measured. One hundred and six showed no change in the x-ray film ‘normal’, (56 male and 50 female), 151 of symptomatic patient’s showed change of knee joint in the plain x-ray ‘diseased’ (55 males and 96 females). Their age range between 18-65 years, bio-data such as height, weight, body mass index heights and circumferences of knees were recorded. In this study we found that there is a significant difference between the height and circumference of the knee for male and female, but there is inclusive differences regarding Rt and Lt knee in normal cases. While the circumference of the knee showed a significant difference between those with remarkable x-ray changes and the symptomatic one without obvious x-ray changes. In conclusion we can estimate the symptomatic patient without changes in X-ray from those with changes by using their age, body mass index and period of disease in a multi-regression equation to predict each groups where the index of possibility increase 0.009, 0.003 and 0.015 for age, period of disease and body mass index respectively; where index one indicate no change in x-ray and index two indicate presence of changes.Item Effects of gum Arabic ingestion on body mass index and body fat percentage in healthy adult females: two-arm randomized, placebo controlled, double-blind trial(Nutrition Journal, 2012) Babiker, Rasha; Merghani, Tarig H; Elmusharaf, Khalifa; Badi, Rehab M; Lang, Florian; Saeed, Amal MBackground: Gum Arabic (acacia Senegal) is a complex polysaccharide indigestible to both humans and animals.
