hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. the present study was done to determine sonographic changes in acute viral hepatitis. we performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male) with acute viral hepatitis. gallbladder wall thickness was se...

conclusions igm alone is not a marker for viral shedding in genital tract. molecular testing in conjunction of igg test should be evaluated as an option to determine hsv status, and applied for research on hsv genital infections records. methods two hundred and eight females were included in the study; igm antibodies against hsv1/2 were detected in serum samples; the real-time polymerase chain ...

waterborne epidemics of viral diseases have occurred and been reported over the years, and isolation of viruses from water of different sources has been made possible by different methods of concentration. it is now believed that bacterial parameters of water purity may not provide an adequate index as to the safety from a virological point of view. in this study eight samples from four main te...

conclusions our findings indicate that patients with the homozygous cc genotype in the il28b gene had a significantly higher rate of response to treatment than those with the tt or ct genotypes. nor does the il28b rs12979860 polymorphism affect the viral load. results the genotype frequencies of rs12979860 polymorphism in group 1 were cc (28.9%), ct (37.8%) and tt (33.3%) and in group 2 were cc...

conclusions the newly developed simple indirect elisa showed high sensitivity and specificity with respect to vnt. developing such a simple, sensitive, and specific elisa which is much less expensive than the available commercial elisa kits can improve the detection of bvdv infections, help to eliminate the disease from herds, and decrease economic losses caused by this disease. background bovi...

measles is one of the viral and extremely contagious and acute diseases of childhood affecting almost all children. prior to the discovery of the measles vaccine, the mortality from this disease was one of the highest child mortality figures, especially in the developing countries, with the death rate ranging over 5 to 10% of the infected? before the vaccination program i was launched in the co...

context several risk factors play the role in the development of hepatocellular carcinoma (hcc) from which chronic hepatitis b and c infections are the most important ones. dna integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. evidence acquisition there are remarkable geographic differences in prevalence of c...

introduction mild intermittent asthma is common in children and viral infections are responsible for the majority of exacerbations. as leukotrienes are potent inflammatory mediators, some studies have shown that montelukast, a leukotriene receptor antagonist, may be effective on reduction of asthma symptom. to determine whether a short course of montelukast in asthmatic children with common col...
