Use of high fiber waste to produce low-fat baton saleh and its metabolic effects in rats

Low-fat baton saleh was produced by partial replacement of butter oil of the control with different sources of fiber-based fat replacer. The best five treatment [sensory evaluation basis] as well as control were evaluated in rats to test their effects on serum lipids [total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides and VLDL], fatty acid composition of rat liver and kidney lipids, body weight gain and organs weights. Feeding rats low-fat baton saleh diets prepared with different fat replacers and two level [30% for rice bran, pomegranate peels and peanut hulls, 45% for guava seeds and chickpea hulls] resulted in a significant decrease in total serum cholesterol, low- density lipoprotein [LDL-cholesterol, triglycerides [TG] and VLDL compared to rats fed the control diet. Liver and kidney lipids in rats fed the low-fat baton saleh diets had lower percentages of palmitics, stearic, myristic, and palmitoleic acids compared to the control. In contrast, percent compositions of linoleic and linolenic acids were greater in rats fed low-fat baton saleh diets

role of laryngeal electromyography in vocal fold immobility

Vocal fold paralysis could be caused by a wide variety of etiological factors that interfere with the nerve supply of the larynx. To assess the utility of laryngeal-EMG as a diagnostic method for patients with immobile vocal folds and to evaluate its possible role as a prognostic indicator in the management of those cases. The study included 35 patients with unilateral vocal fold immobility [VFI] in addition to 10 normal individuals who served as controls. All patients were subjected to full history taking and thorough clinical examination and radiological investigations. Laryngeal EMG was performed for all the patients and controls. None of the control group showed abnormal EMG data while abnormal EMG findings were detected in 23 out of 35 of the patients' group i.e. the specificity of EMG was [100%] while the sensitivity was [65.7%] in detecting VFI. On clinical follow up with indirect laryngoscopy, 6 months later revealed recovery in 10 of the 25 cases [40%]. None of the recovered patients showed abnormal EMG data at presentation while 13 out of 15 cases of non-recovered patients showed abnormal EMG data i.e. the specificity of EMG was 100% while the sensitivity was 86.6% in predicting recovery in patients with VFI. The quantitative analysis of the interference pattern was more sensitive [65.7% and 86.6%] than the conventional methods of analysis [60% and 80%] in detecting and predicting recovery in patients with immobile vocal folds respectively. The clinical use of L-EMG was shown to be an efficient and objective test in the study of patients with immobile vocal folds and in predicting recovery of those cases

study of the antioxidant properties of propofol

This clinical study was done to explore the changes in oxidative system in RBCs from surgical patients anaesthetized with propofol. We studied 40 patients who were divided into two groups 20 patients each. Group I was induced by 4 mg/kg iv. thiopental followed by halothane for maintenance. Group II was induced by 2 mg/kg iv. propofol, followed by iv. infusion of propofol for one hour to maintain anaesthesia. We measured the following variables in RBCs: glutathione content, oxidized glutathione, glutathione peroxidase and lastly serum selenium. We found that propofol decreased oxidized glutathione from 10.24 +/- 0.4 to 9.1 +/- 0.6 micro g/ml [p < 0.05] and increased the other three variables after bolus dose and iv. infusion from [638 +/- 7.5 to 676 +/- 10 micro g/ml] [29.6 +/- 1.9 to 30.9 +/- 2.2 micro g/g Hb] [12.5 +/- 6.68 to 13.9 +/- 9 micro g/dl] [p < 0.05]. Thiopental did not modify any of the variables. In conclusion, the findings showed that propofol has an antioxidant effect in humans, this effect may be beneficial in patients who have diseases in which free radicals play an important role
