The cultivation and migration in vitro of olfactory ensheathing cells from human olfactory mucosa / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the bionomics of the olfactory ensheathing cells (OECs) of human olfactory mucosa.@*METHOD@#To separate and cultivate the OECs of human and rat olfactory mucosa. To observe the cell growth, cell grouping and cell migration in vitro of the two types of OECs.@*RESULT@#Successfully separated and cultivated the OECs of human and rat olfactory mucosa. OECs of the human and rat olfactory mucosa had the similar cell growth, cell grouping and cell migration ability in vitro.@*CONCLUSION@#OECs of the human and rat olfactory mucosa have the similar bionomics in vitro, as a result, OECs of the human olfactory mucosa could be a reliable source of cell transplant for nerve injury.

The investigation for the neuropeptides of nasal septum in perennial allergic rhinitis patient / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the expression of neuropeptides in the nasal septum of the perennial allergic rhinitis patients, and the mechanism of the alleviation effect of nasal septum rectification to allergic rhinitis.@*METHOD@#Forty-five patients with deviation of nasal septum (20 with allergic rhinitis and 25 without), who undergone nasal septum rectification in Changhai hospital during Jun to Dec, 2007, were included in this research. The levels of SP, VIP, CGRP of the nasal septum were determined by radioimmunoassay.@*RESULT@#In the normal controls, the SP, VIP and CGRP levels of the nasal septal cartilages were lower than that of the nasal septal bones (P0.05), and the CGRP level of the nasal septal cartilages was higher than that of the nasal septal bones (P0.05). There were no statistical significance between the CGRP levels of the nasal septal cartilages in the two groups (P>0.05), neither did that of the nasal septal bones in the two groups (P>0.05).@*CONCLUSION@#The SP level of the nasal septum in the perennial allergic rhinitis patients was higher than that in the normal controls, which was more obvious in the nasal septal cartilages. The VIP level of the nasal septum in the perennial allergic rhinitis patients was higher than that in the normal controls, which was more obvious in the nasal septal cartilages. There were no statistical significance between the CGRP levels of the nasal septum in the perennial allergic rhinitis patients and the normal controls.
