Study on the Morphology and Frequency of the Vomeronasal Organ in Humans
Provedor de dados: 77
Autores: Carvalho,Maria de Fátima Pereira de; Alves,Adriana Leal; Barros,Mirna Duarte.
The vomeronasal organ was first described in humans in the seventeenth century. It has a chemosensory function and is found in the mucosa of the nasal septum of mammals and consists of an opening in the mucosa at the base of the nasal septum. For this study, 143 individulas undergoing nasofibrolaryngoscopy were studied, and presence of the vomeronasal organ was considered to be a finding from the examination. Three morphological types of vomeronasal organ were observed: fissure, fossette and circular. The total prevalence of the vomeronasal organ among these patients was 28% (40 individulas ). The prevalence of the vomeronasal organ in this study population is compatible with what has been reported in other studies. The forms of the vomeronasal organ can...

Expression of Neuronal and Non-Neuronal Markers in the Vomeronasal Organs of One-Humped Camel (Camelus dromedarius) and Egyptian Water Buffalo (Bubalus bubalis)

Fourteen vomeronasal organs (VNOs) of adult males one-humped camels (Camelus dromedarius) and Egyptian water buffaloes (Bubalus bubalis) (n=7/each) were examined immunohistochemically with neuronal markers; synaptophysin (SYP) and glial fibrillary acidic protein (GFAP) to clarify the distribution of the vomeronasal (VN) receptor cells and nerve fibers, in addition to elucidate the existence of non-neuronal elements via S-100 and endothelial nitric oxide synthase (eNOS). In both animals, the VNO was lined medially with VN sensory (olfactory) epithelium and non-sensory (respiratory) epithelium laterally. Immunohistochemically, both animals showed SYP immunolabeling only in the receptor cells of VN sensory epithelium while GFAP labeled the ensheathing cells...

Androgen Receptor Distribution, PAS and Alcyan Blue Reaction in the Vomeronasal Organ and the Nasal Septum Mucosa of the Developing Male Rat
Provedor de dados: 77
Autores: Núñez Chichet,M E; Genovese,P; Bielli,A.
The vomeronasal organ (VNO) is a tubular chemoreceptory organ which detects environmental pheromones and is essential for mammalian normal reproductive activity. A sensitive chemoreceptory neuroepithelium lines the concave VNO wall and the opposite, convex wall is lined by a seudostratified, receptor-free epithelium. The secretion of the Jacobson glands (JG) -tubuloacinary glands lying in the lamina propia of the VNO - is essential for pheromones contacting vomeronasal organ chemoreceptors. Tubuloacinary glands lying in the connective tissue of the nasal septum mucosa (Bowman glands), can be classified as ventral and dorsal, according to their location. Positivity to PAS and Alcyan blue reactions and androgen receptor immunolocalization was evaluated with...

Volatile female odors activate the accessory olfactory system of male mice without physical contact
Provedor de dados: 19
Autores: Muroi, Yoshikage; Ishii, Toshiaki; Komori, Seiichi; Kitamura, Nobuo; Nishimura, Masakazu; 室井, 喜景; 石井, 利明; 北村, 延夫.
We previously reported that male mice are more attracted to volatile odors from intact female mice than from ovarlectornized female mice. In the present study, we investigated male attraction to volatile odors from soiled bedding collected from the cages of estrous or ovariectomized female mice. There was no difference in the total time spent sniffing volatile odors from estrous and ovariectomized female mice, suggesting that female mice emit volatile odors which are not excreted into bedding. To test this possibility, we investigated c-Fos expression in the mitral cell layer and granule cell layer of the accessory olfactory bulb 60 min after exposure of male mice to volatile odors without physical contact. Volatile odors from an estrous female mouse...
