Experimental Hydrocephalus
Internal hydrocephalus can be produced experimentally by injecting a foreign substance into the ventricles. In these experiments, aleuronat, a granular, insoluble material, has caused an acute inflammatory reaction, characterized in the first week by an exudate consisting largely of polynuclear leucocytes. Later the picture is one of a chronic process; polynuclear cells are replaced by lymphoid...
متن کاملAngioarchitecture in experimental hydrocephalus.
The angioarchitecture of microcorrosion casts in 12 hydrocephalic rats and 5 normal control rats was investigated by using scanning electron microscopy to observe the changes of the vascular bed in the cerebral mantle in hydrocephalus. Reduction in the number and caliber of the capillaries in the white matter was the most remarkable change in the hydrocephalic rats. This change increased in pro...
متن کاملChronic Hydrocephalus after Experimental Subarachnoid Hemorrhage
Chronic communicating hydrocephalus is a significant health problem affecting up to 20% of survivors of spontaneous subarachnoid hemorrhage (SAH). The development of new treatment strategies is hampered by the lack of well characterized disease models. This study investigated the incidence of chronic hydrocephalus by evaluating the temporal profile of intracranial pressure (ICP) elevation after...
متن کاملSonographic evaluation of experimental hydrocephalus in kittens.
Real-time computed sonography was used to monitor ventricular size in kittens with experimentally induced hydrocephalus. Hydrocephalus was induced by cisternal kaolin injection in newborn kittens in order to study the effects of both hydrocephalus and subsequent ventriculoperitoneal shunting on the morphology of brain tissue. When severe hydrocephalus was achieved, marked physical and neurologi...
متن کاملExperimental Studies on Inflammation
1. Wright's method for the study of chemotaxis of leucocytes in vitro, slightly modified, has been found to be most satisfactory in the estimation of the degree of chemotaxis of various substances, because it is possible to make an exact quantitative determination of the leucocytes that have migrated from the blood clot and adhere to the surfaces containing the tested substance. 2. The calcium ...
