BACKGROUND To assess the role of DWI in differentiation haemorrhagic ovary infarction from non-haemorrhagic one. METHODS For this prospectively designed study, of 117 female patients who presented with acute lower quadrant pain and underwent MRI for suspicion of ovary torsion, results of only 29 patients (mean age, 24.7; SD, ±5.7; age range, 18-37), with surgical and pathological confirmation...

haemorrhagic septicaemia (hs) vaccine which is prepared in razi institute is used in endemic areas ofiran. aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. post-vaccinal shock reactionswere the main complaint after use of this vaccine. in a previous study, we could improve the vaccine byalum-precipitation pasteurella multocida cells and removing the liquid phase. in this ...

BACKGROUND The clinical epidemiology of stroke has been widely investigated in Caucasian populations, but the changes over time in the proportion of ischaemic to haemorrhagic strokes is less clear, especially in the Chinese population. AIMS Our objective was to study the determinants and time trends for ischaemic and haemorrhagic stroke, in relation to age, in a large Chinese population cohor...

egg-laying hens were immunized with the echis carinatus venom and the resulting antibodies were extracted from egg yolk by four different purification methods. the chicken egg yolk antibodies were purified by the water dilution method, polyethylene glycol (peg) and ammonium sulphate precipitation method, chloroform extraction and the lithium sulphate precipitation method. these methods were com...

pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. the objective of the current study was to review the genetic b...

BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...

Six hundred 1-d old male broilers (Ross 308) were assigned into four experimental groups; each was composed of 5replications of 30 birds including control (0), 10, 20 and 40 mg/kg nano-ZnO in the basal diets. Birds were exposed to low ambient temperature (15 to 18 ˚C) to induce ascites. Blood parameters including; activity of aspartate transferase (AST), alanine transferase (ALT), lactate dehyd...

The increasing susceptibility of broiler chickens to ascites syndrome has coincided with a continuing genetic and nutritional improvement in their feed efficiency and growth rate. Ascites is multifactorial and interactions between environmental and endogenous factors play a particularly important role. The selection of fast growing broilers for high feed efficiency, which is characterized by hy...
