Study Properties of Fermented Camels’ and Goats’ Milk Beverages Fortified with Date Palm (<i>Phoenix dactylifera L</i>.)

Food and Nutrition Sciences 2021年第5期12卷 418-428页

作者： Meranda A. Tawfek enas A. Baker Howida A. El-sayed Dairy Sciences and Technology Research Department Food Technology Research Institute Agricultural Research Center Giza Egypt

Camels’ milk (CM) and goats’ milk (GM) are rich in nutrients and vitamins necessary for the health of humans and have therapeutic properties as they are rich in antioxidants and have a protective role against free radicals that have harmful effects on human health. Date palm (DP), camels’ milk and goats’ milk have been reported to be used for the prevention and treatment of various diseases in Arab countries. This study was designed to mix date palm with camels’ milk and goats’. Eight formulations of both camels’ milk and goats’ were made from different percentages of date palm. These formulations were added at ratios of 0 (control), 10%, 20% and 30% (w/v) to camels’ milk and goats’ and the effect of this date palm on the composition and texture properties of the fermented obtained products were followed. It has been found that pH, protein, fat decreased and total solid, carbohydrate, ash, viscosity, vitamins, minerals and antioxidants increased with the increase of the added percentage of date palm compared to control. Microbial counts of the fermented camels’ milk (FCM) and goats’ milk (FGM) increased significantly (P improved the composition, viscosity, microbiological quality of fermented camels’ and goats’ milk with nutritional functional values and acceptable sensory attributes.

Use of the urinary trypsinogen-2 dipstick test in early diagnosis of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP)

引用

Open Journal of Gastroenterology 2013年第6期3卷 289-294页

作者： Hasan El-Garem enas Hamdy Sherif Hamdy Mohammad El-sayed Aisha Elsharkawy Azmi Mohammed Saleh Department of Clinical Pathology Faculty of Medicine Cairo University Cairo Egypt Department of Endemic Medicine and Hepatology Faculty of Medicine Cairo University Cairo Egypt

Background: Acute pancreatitis is one of the most serious complications of ERCP. Early diagnosis of post ERCP pancreatitis helps physicians to provide intensive care and possible medical treatment as early as possible. Trypsinogen-2 in urine is a good diagnostic and prognostic marker of acute pancreatitis. Objectives: To evaluate the diagnostic value of urinary trypsinogen-2 dipstick test for early diagnosis of post ERCP pancreatitis. Methods: A total of 37 patients with obstructive jaundice were tested with the urinary trypsinogen-2 dipstick test and serum levels of amylase and lipase before ERCP and 6 hours after ERCP. Results: Post ERCP pancreatitis was diagnosed in 6 (16%) of 37 patients. The sensitivity, specificity, positive predictive value and negative predictive value of urinary trypsinogen-2 dipstick test at 6 hours after ERCP were 100%, 97%, 86%, 100% respectively. At the cutoff level (130 U/L) for lipase, the positive predictive value and negative predictive value all were (100%), however, the positive predictive value and negative predictive value for amylase levels at cutoff (122 U/L) were 60%, 100% respectively. Serum lipase level was the best test for diagnosing post ERCP pancreatitis followed by the urinary trypsinogen-2 dipstick test. Conclusions: The urinary trypsinogen-2 dipstick test can be used as a rapid and easy test for early diagnosis of post ERCP pancreatitis with high sensitivity and specificity.
