[Structural changes in the central nervous system of dogs with a combined bilateral lesion of the carotid arteries].

In the experiment 20 dogs were subjected to bilateral kinking of the carotid artery and the effects were assessed angiographically and radiologically as well as changes in the cerebral cortex. It is shown that 30 degree kinking produced more significant ultrastructural changes which in most cases were reversible.

[Morphological changes in the central nervous system of dogs with unilateral lesions of carotid arteries].

16 dogs were subjected to either ligation or kinking of a single carotid artery and the resultant changes in the cortical hemisphere were studied. Light and electron microscopy findings indicate reversibility of the induced pathological processes both in microcirculation and in neurons proper.

[Tuberculomas of the brain].

Literature data and individual observations of 5 cases with a rare disease, like tuberculoma of the brain, are presented. From the clinical point of view, the disease in children, aged 4-9 years, proceeds like cerebral tumor. A surgical intervention has revealed a tuberculoma of the cerebellum in 4 and that of the truncus cerebri in 1 patient.

[Open injuries of the brain from the anatomo-clinical aspect].

A combined clinico-pathological and experimental investigation of the open traumatic brain lesions was performed. Clinical investigation of 266 patients is presented along with pathological findings in 9 autopsied brains of victims of craniocerebral trauma which died at different terms after the injury. Experimentally investigated were 25 cats with brain lesioned at various sites.

[Condition of interocortical connections in cranio-cerebral injuries with inferior parietal lobe lesions].

The intercortical pathways and the clinical picture of the condition developing after an injury of the parietal lobe of the human brain were studied pathomorphologically (10 cases) and clinically (103 observations). It was shown that in cases of injury of the lower parietal region there developed a degeneration of the nervous fibres in various areas of the cortex of both the ipsi- and the contralateral hemisphere. Certain regularities of the distribution of the degenerated nervous fibres among the cortex areas were revealed, and their topics in various parts of a groove shown.

[Ultrastructure of cerebral cortical synapses in closed craniocerebral injuries].

The brain of 5 individuals with an open craniocerebral trauma was examined with an electron microscope. Changes in interneuron structures were found. Occasional synaptic vesicles grow in size and move away from the presynaptic membrane.

[Histomorphologic changes following plastic repair of defects in spinal dura mater with a capron strip in complicated experimental fractures of the spine].

A wide incision of the dura mater of the spinal cord helps to inspect the subdural space in detail. If there is a defect in the dura mater, or if it is impossible to suture it due to edema and swelling of the spinal cord, it is rational to resort to plastic replacement with a band of capron mesh which resolves completely by the end of the third year after the surgical intervention.

[Prevention of postural reactions in patients with spinal cord lesions].

Changes in the cardiovascular system in 83 patients with spinal cord affections were studied before operation and during the anesthesia period. Disorders in the cardiovascular system up to cardiac arrest occur during operation in patients who have been, bed-ridden for more than 3--4 weeks. The authors suggest that training on a table-bed should be included into the complex of preoperative preparation of the patients; this prevents different coarse disorders and cardiac arrest during operation.
