The distribution and localization of acid and neutral mucins in various cells lining the olfactory epithelium of Cyprinus carpio have been studied histochemically by employing the PAS-AB technique. Variations in the localization of protein in different cells lining the olfactory epithelium have been correlated with the functional significance of the region concerned. Intense localization of t...

organization of various cells lining the olfactory mucosa of puntius ticto (hamilton, 1822) were described by light as well as scanning electron microscopy. the paired olfactory chambers located antero-dorsal to the eyes and communicated outside through anterior and posterior nasal openings. the oval shaped olfactory rosette lied at the bottom of chamber and composed of 18-20 lamellae arranged ...

the cellular organization of the olfactory epithelium of puntius sarana (hamilton, 1822) was explored by means of optical and scanning electron microscopy. the oval shaped olfactory rosette was composed of 26-28 primary lamellae distributed from both sides of the central raphe. the sensory epithelium confined chiefly on the linguiform processes of the lamella and rest of the portion consisted o...

objective(s): in the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. cellular characteristics and functional plasticity of globose basal stem cells (gbcs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the ...

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...

the present study is related to the histochemical investigations on the changes in the intensity of reactions of axons, acid and neutral mucopolysaccharides, biologically active macromolecules, particularly glycogen and protein component as well as alkaline phosphatase (alpase) and adenosine triphosphatase (atpase) in the cells lining the olfactory epithelium of catla catla . the intense reacti...

Induction, neurogenesis, and synaptogenesis of the olfactory bulb are thought to require interactions with the olfactory epithelium. The Dlx family of homeobox genes is expressed in both the olfactory bulb and olfactory epithelium. In particular, Dlx5 is expressed in the olfactory placode, olfactory epithelium, and local circuit neurons of the olfactory bulb. Here we analyzed mice lacking DLX5 ...

Olfactory cells receive numerous odorants including toxic substances. To avoid complete loss of the olfactory function by toxic odorants, continuous neurogenesis of olfactory cells occurs even at adulthood. Newly generated olfactory neurons extend their axons to the olfactory bulb. Various molecules including polypeptides, proteins, polynucleotides, virus, and cells administrated intranasally h...
