in this paper the histopathological observation of the migratory phase of schistosome larvae (schistosomulae) in the laboratory animal were studied. the first tissue samples were taken from the skin of infected animals 30 minutes after exposure to the cercariae and continued daily up to 40 days post infection. the tissue specimens were taken from skin, liver. lung, lymph nodes, kidney, brain, b...

brain injury is a complex event leading to tissue damage and functional deficits by primary and secondary mechanisms. since the application of tissue engineering approaches is a new topic in the treatment of brain injury, producing a proper experimental model to evaluate the effects of tissue engineering products on damaged brain tissue is required. in the present study, a simple and reproducib...

spinal cord injury (sci) leads to a significant health problem associated with a broad range of secondary complications and disabilities. in this regard, animal models can help us to understand the pathobiology of sci and evaluate the effects of potential treatments for sci. in contusion models of sci, different devices including surgical spring-loaded clips, balloons, forceps, weights and the ...

mitral valve regurgitation (mvr) is a common valvular disease in dogs. hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (vfm), which shows the blood flow within the ventricles in vector and vortex flows. blood flow within the left ventricle of mvr dogs was compared at different stages of mvr and to that of normal dogs. 14 normal dogs and...

introduction: full crown preparation may have adverse effects on pulp tissue. in this study, the effect of full-crown preparation on intact versus inflamed pulp tissue was studied. methods: fifteen healthy mature cats were randomly selected for this study. the study was performed on four canine teeth of each cat. cats were anesthetized and then radiographs were taken from the canine teeth. clas...

during last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. however, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. in this paper we examined dung germinating seed content, seed deposition p...
