Comparative Morphology of Fish Olfactory Epithelium-III

cadmium induced histopathology in the olfactory epithelium of a snakehead fish, channa punctatus (bloch)

histopathology on the olfactory organ of a snakehead fish, channa punctatus (bloch, 1793) were assessed after exposing the fish to 2.5 mg/l and 5mg/l of cdcl 2 for 15 days, 30 days and 45 days. cellular organization of the epithelium was affected severely with degeneration of sensory and supporting cells and hyperplasia of basal cells and mucous cells. mucous cell proliferation indicates the up...

Biopsies of human olfactory epithelium.

It has been shown that olfactory epithelium can be safely biopsied from the living, intact human being. Observations of the ultrastructure of this epithelium shows changes that can then be correlated with the etiology and degree of olfactory loss, allowing a greater understanding of both normal transduction and of the pathology of dysfunction. Examples of the common forms of olfactory dysfuncti...

Histological and ultrastructural studies of the olfactory epithelium of spotted butter fish Scatophagus argus (Linnaeus).

The olfactory epithelium of Scatophagus argus (Linnaeus) was investigated by light and scanning electron microscopy. The elongated olfactory organ is made up of 20 to 22 primary lamellae arranged on both sides of the narrow median raphe. Sensory and non-sensory regions are located separately on each lamella. The sensory epithelium occupies the upper apical broad half and extreme basal part of t...

The Effect of Hyperstimulation and Progesterone Injections on the Morphology of Mouse Vaginal Epithelium

Purpose: The aim of this study was to evaluate the morphological changes of vaginal epithelium after hyperstimulation and daily injection of progesterone followed ovarian hyperstimulation. Materials and Methods: Forty 8-10 week old virgin female mice were selected and divided in four groups. Two experimental groups were hyperstimulated using ip injection of 10 Iu of human menopasula gonadotrop...
