[Clinico-morphologic characteristics of brain contusion in patients of various age groups].

Brain contusion in children becomes fatal only when the cerebrocranial trauma is very serious and coarse diffuse lesions occur in the whole brain. Foci of intracerebral hemorrhages are relatively rare in such cases. A special form of affection--diffuse involvement of the brain is often encountered in children and young persons.

[Status of cerebral ventricles and meninges in subarachnoid hemorrhage (clinico-pathomorphological studies)].

Long-term investigation of 64 patients with subarachnoidal hemorrhages (SH), 24 of which had subsequently died, and 2 series of experiments of animals with a single or repeated intracysternal infusion of various doses of autologous blood, yielded the description of the response of the meninges and ventricles at different terms after SH. The brain ventricles were measured by axial computer tomography and echoencephalography. A index of CSF resorption resistance and CSF pressure were determined.

[Toxicity of anti-tumor preparations after intracranial, subarachnoid and suboccipital administration (experimental study)].

Experiments were conducted on animals to study intrathecal injection of agents differing in the mechanism of action: variamycin, mitramycin, reumycin, proxyphein, and prospidin. Their acute toxicity in a single intracerebral injection and chronic toxicity in repeated suboccipital injection were studied. The brains of animals who died or were killed were studied pathomorphologically in different periods.
