BACKGROUND A simple scoring system is needed to discriminate HCC from patients with chronic liver diseases (CLD). The simplest score would be one that requires only variables that can be documented simply from routine laboratory tests without the need for sophisticated tests. METHODS Data from the estimation group (1351 patients) and the validation group(More)
Studies were conducted to investigate the interaction of renal prostaglandin E2 (PGE2) production and the renin-angiotensin system in the mechanism of furosemide-induced natriuresis. In conscious rabbits with permanent urinary bladder cannulation, furosemide in vivo (10 mg/kg) increased urinary water, sodium, and PGE2 excretion and plasma renin activity(More)
UNLABELLED BACKGROUND AND RATIONALE FOR THE STUDY: The assessment of liver fibrosis provides useful information not only for diagnosis but also for therapeutic decision. This study was concerned with determining the levels of collagen III and its degrading enzyme matrix metalloproteinase-1 (MMP-1) as direct and complementary markers for liver fibrosis(More)
To test the hypothesis that renal PGs may mediate the renal functional defect of potassium depletion, rabbits were placed on normal potassium and potassium-deficient diets for 7 weeks, and measurements were made of urinary PGE2 excretion; renal cortical, medullary, and papillary PGE2 content; and in vitro, de novo PGE2 biosynthesis. In the sixth week(More)
BACKGROUND Several noninvasive predictive models were developed to substitute liver biopsy for fibrosis assessment. AIM To evaluate the diagnostic value of fibronectin which reflect extracellular matrix metabolism and standard liver functions tests which reflect alterations in hepatic functions. MATERIAL AND METHODS Chronic hepatitis C (CHC) patients (n(More)
BACKGROUND AND STUDY AIMS Non-invasive methods for the assessment of liver fibrosis are clinically important where hepatitis C virus (HCV) is common in Egypt. Our aim was to evaluate the diagnostic performance of a panel of simple blood markers of liver fibrosis in chronic hepatitis C (CHC) patients. PATIENTS AND METHODS A total of 199 patients with CHC(More)
Immunoreactive prostaglandin E2 (PGE2) was measured in slices of renal papilla (P), outer medulla (OM), and cortex (C) before and after 30 min of incubation (biosynthesis) in Krebs-Ringer HCO3- buffer in rabbits on low (LS), normal (NS), and high (HS) sodium diets. The 24-h urine PGE2 was also measured daily for 10 days prior to incubation. Daily urine PGE2(More)
Urinary PGE2 and PFG 2 alpha excretion (UPGV) were determined prior, during and after 48 h treatment with angiotensin-II-blocker, Sar1-Ile8-angiotensin II (200 microgram/kg/3 h), in rabbits maintained on chronic low (LS) or high (HS) salt diets. UPGE2V and F2 alpha were significantly (P < 0.001) higher in LS than in HS. Sar1-Ile-8-angiotensin II decreased(More)
