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 ...

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...

This study was carried out to investigate the histological and anatomical description of the male genital tract in Iranian Native White Roosters (IWR). The seminiferous tubules had a dense and compact organization. An average of 12 layers of cells was seen in the seminiferous tubules epithelium. The spermatogonal cell layer showed some variation between different birds in 1-3 layers; however, t...

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 ...

soft tissue-implant interface is an important anatomical feature contributing to the long-term success of dental implants. based on the available evidence, different factors may influence biological width around implants including the surgical technique, implant loading, implant surface properties, abutment materials, implant position, and width of the peri-implant mucosa. the purpose of the pr...
