Morphologic and Ultrastructural Changes

Morphologic Changes in Vascular Dementia

Morphologic changes in cortex and white matter of the cerebral frontal lobes in vascular dementia were studied. The signs of leykoaraiosis in white matter were revealed. Obvious signs of neurodegeneration expressed in loss of neurons, which is considered to be the attribute of aging process and may be one of significant etiologic factors of vascular dementia, had not been identified.

Morphologic Changes in Pulmonary Emphysema.

I NTENSE INTEREST EXPRESSED BY CLINIcians, physiologists, and pathologists in pulmonary emphysema has stimulated the need for establishing some criteria for the normal anatomy and subsequent pathologic change. Regardless of the conflict in the theories of etiology, we must be cognizant of certain changes which take place in the pulmonary parenchyma. The fine relationships between structure, fun...

Gastric Carcinoma: Morphologic Classifications and Molecular Changes

Ultrastructural Changes of Sheep Oocytes Follow Vitrification by Different Methods and In Vitro Maturation

Purpose: Our aim was determination of the sheep oocytes ultrastructural changes follow vitrification and in vitro maturation. Materials and Methods: Good quality isolated cumulus-oocyte complexes (COCs) were randomly divided into non-vitrified control, conventional straw, cryotop and solid surface vitrification groups. In the conventional and cryotop methods the vitrified COCs were plunged dire...

Morphologic Changes of Adrenal Cortex in Disease

Stimulation of the adrenal cortex by the "stress" of illness is now taken for granted. Numerous publications have described changes in adrenal cortical histology in particular diseases, and at least one author' has attempted a general study of the adrenal cortex in an autopsy population. Even so little attention is paid the adrenal cortex in the average autopsy performed by the average patholog...
