Long-term changes in the ipsilateral substantia nigra after transient focal cerebral ischaemia in rats.
Transient focal cerebral ischaemia can cause neuronal damage in remote areas, including the ipsilateral thalamus and subsutantia nigra, as well as in the ischaemic core. In the present study, we investigated long-term changes in the ipsilateral substantia nigra from 1 up to 20 weeks after 90 min of transient focal cerebral ischaemia in rats, using tyrosine hydroxylase (TH), neuronal nuclei (Neu...
متن کاملUltrastructural Study of Cadmium Effects on Photoreceptors and Ganglionic Cells of Retinal Layer in Mice Embryo
Purpose: In this study, TEM was used to asses the ultra structural effects of Cd on Photoreceptor and Ganglionic cells of mouce retinal layer. Materials and Methods: 30 mice hi1Vebeen used in three groups (experimental I, II & control). On 9th day of gestation, experimental groups have received a single IP injection of Cadmium- chlorid (Cd C12) solution in saline, 3 mg/kg and 5 mg/kg respectiv...
متن کاملBlood-brain barrier disturbances and morphological changes in rat brain after photochemically induced focal ischaemia.
The disturbances in cerebral circulation lead to focal brain ischaemia and brain infarcts. The pathogenesis of brain ischaemia has been a subject of numerous experimental studies employing different models and focusing on the anatomy of collateral circulation. The aim of this study was the evaluation of our own model of focatcerebral damage caused by a photodynamic reaction, and determination o...
متن کاملInhibition of Pseudomonas aeruginosa by hyperbaric oxygen. II. Ultrastructural changes.
The ultrastructure of Pseudomonas aeruginosa cells treated with hyperbaric oxygen for 20 to 24 hr was examined by electron microscopy. A marked difference in the morphology of the nuclear area and cytoplasm of experimental cells was noted when compared to control cells grown under normobaric conditions. This difference was characterized by the absence of a definitive nuclear area and a reduced ...
متن کاملAmbulatory electrocardiographic monitoring in patients with transient focal cerebral ischaemia.
Sixty-four patients with transient ischaemic attacks were investigated for the presence of an associated cardiac arrhythmia. 24-hour ambulatory monitoring showed arrhythmia in 41% of patients where the standard ECG had shown arrhythmia in only 25%. Significant arrhythmias were found in 21% of patients with focal transient ischaemic attacks on prolonged monitoring as compared to 7% in a control ...
