Immunocytochemistry at the Electron-Microscopic Level

Localization of nucleolar chromatin by immunocytochemistry and in situ hybridization at the electron microscopic level.

Nucleoli are the morphological expression of the activity of a defined set of chromosomal segments bearing rRNA genes. The topological distribution and composition of the intranucleolar chromatin as well as the definition of nucleolar structures in which enzymes of the rDNA transcription machinery reside have been investigated in mammalian cells by various immunogold labelling approaches at the...

Light and electron microscopic study of the tongue in the White-eared bulbul (Pycnonotus leucotis)

The aim of the present study was to investigate the light and electron microscopic structure of the tongue in White-eared bulbul (Pycnonotus leucotis). Six adult White-eared bulbul (3 males and 3 females) in Shahrekord district were used in the investigation. Samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. Results showed that th...

Light and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)

BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...

Electron microscopic alterations at the alveolar level in pulmonary edema.

The electron microscopic alterations of the alveolar septum in advanced hemodynamic and alloxan-induced pulmonary edema were compared. Pulmonary edema was produced in anesthetized dogs by means of increased left atrial pressure and hemodilution and by alloxan administration. Sections of pulmonary tissue from these dogs and similarly anesthetized controls were processed for and examined by light...
