[Influence of posterior capsule striae on visual acuity in the first year after implantation of different intraocular lenses].

Unlabelled: Posterior capsule striae are the typical consequence of phacoemulsification; the data of their influence on visual acuity is still contradictory.

Purpose: To estimate the influence of posterior capsule striae on visual acuity within one year after implantation of three models of acrylic intraocular lenses (IOLs).

Material And Methods: Seventy-two patients (91 eyes) were followed up for 12 months after implantation of one of models of IOLs: MIOL-2 (24 eyes, first group), SA60AT and US60MP (41 and 26 eyes, second and third groups, respectively).

[Pathology of the nervous system: clinico-morphologic study in multiple myeloma].

Histopathologic changes in the brain and spinal cord in multiple myeloma are similar to those seen in toxic encephalopathy with circulatory disorders. Irreversible morphologic changes in the brain and spinal cord are more pronounced in the encephalopathic syndrome. The structures affected most are the cerebral cortex, brain pedicles, medulla oblongata, spinal cord and its radicles.

[Selectivity of cerebral neuronal lesions in atherosclerosis].

Clinical, histological and biochemical studies of the brain in 100 cases of atherosclerosis with relatively similar intensity of changes in the cerebral vascular walls (over 50% of the intima surface being impaired) were carried out. Correlation of the corresponding parameters in groups of diseases differing by their clinical picture permitted the author to ascertain that the selective vulnerability of the cortical neurons in the cerebral hemispheres is dependent on both the intensity of their physiological activity and on the nature of lipid metabolism disorders secondary to dystrophic processes.
