Despite the great progress in modern medicine, traditional medicine has always been practised in the Arab-Islamic world. Cultural beliefs and practices often lead to self-care or home remedies in rural areas and consultation with traditional healers. Traditional therapies have been utilized by people in the Mediterranean region who have faith in spiritual healers, homeopaths or even many herbalists. These are the first choice for problems such as infertility, impotence, diabetes, obesity, epilepsy, psychosomatic troubles and many other diseases. The modern use of Arab botanical medicines has historical roots in ancient Arabic medicine. In the Middle Ages Arab herbalists, pharmacologists, chemists and physicians adapted the ancient medicinal practices of Mesopotamia, Greece, Rome, Persia and India. Medical innovations introduced by Arab physicians included: the discovery of the immune system, the introduction of microbiological science, and the separation of medicine from pharmacological science. This chapter presents a systematic review on traditional Arab botanical medicine including historical background, medical innovations introduced by Arab and Muslim physicians, and a state of the art description of traditional Arab herbal medicine.

1. The present study was designed in an attempt to resolve conflicting views currently in the literature relating to the effect of surgery on various aspects of protein metabolism. 2. Sequential post-operative (2, 4 and 6 days) changes in whole-body protein turnover, forearm arteriovenous difference of plasma amino acids, glucose, lactate and free fatty acids, muscle concentration of free amino acids, RNA and protein, urinary nitrogen and 3-methylhistidine, plasma concentrations of insulin, cortisol and growth hormone, and resting metabolic rate, were measured in six patients undergoing uncomplicated elective total abdominal hysterectomy. 3. All patients received a constant daily diet, either orally or intravenously, based on 0.1 g of nitrogen/kg and an energy content of 1.1 times the resting metabolic rate for 7 days before and 6 days after surgery. 4. Whole-body protein turnover, synthesis and breakdown increased significantly 2 days after surgery (P less than 0.05) and returned towards pre-operative levels thereafter. 5. Forearm release of branched-chain amino acids and alanine, and efflux of glucose and lactate, were enhanced 4 days after surgery (P less than 0.05). Muscle glutamine and alanine concentrations were decreased on the fourth and sixth days after surgery (P less than 0.05). The RNA/protein ratio (indicating the capacity for protein synthesis) was unaltered. 6. A significant increase in urinary nitrogen and 3-methylhistidine was observed on days 3 and 4 after surgery (P less than 0.05). Thereafter, these parameters remained elevated, although failing to reach statistical significance.(ABSTRACT TRUNCATED AT 250 WORDS)

A considerable amount of attention has focused on the cardiovascular events associated with ethanol consumption. The available evidence suggests that moderate ethanol consumption is associated with reduced risk of coronary heart disease, i.e., vessel events. In contrast, this review is primarily concerned with ethanol and heart muscle damage. Clinical features of the consequences of prolonged and excessive ethanol consumption encompass defects in myocardial contractility and derangement of cellular architecture, including disarray of the contractile elements. Although the incidence of heart muscle abnormalities in alcohol misusers is generally higher than previously considered, the mechanisms are only just being elucidated. This process has been facilitated by laboratory based studies in which animals receive either a single dose of ethanol (acute studies) or a continuous supply of ethanol in their daily diets (chronic studies). Results from these models show that acute ethanol dosage causes a marked decrease in the synthesis of contractile proteins. This occurs in the absence of overt mitochondrial abnormalities: ATP concentrations are generally unaffected. Paradoxically, the synthesis of mitochondrial proteins is reduced. Use of metabolic inhibitors suggests that the deleterious effects of acetaldehyde contribute to these reductions in protein synthesis. In chronic studies, ethanol causes a reduction in the amount of contractile proteins, and two dimensional protein profiling implicates selective loss of individual myocardial proteins. The differential activities of lysosomal proteases may contribute to this patterned response. However, in chronic ethanol feeding, adaptive mechanisms also become important, as the synthesis of the myofibrillary proteins increases. Overall, the mechanisms inherent in these biochemical responses may contribute to the genesis of a distinct disease entity, alcoholic heart muscle disease.
