ABSTRACT
@#Tornwaldt (Thornwaldt) or nasopharyngeal cyst is a cyst occurred at the connection site of pharyngeal endoderm and notochord remnant, usually located in the midline postero-superior wall of nasopharynx. Nasopharynx’s obstruction, recurrent infection or trauma may exacerbate mucous secretion by the potential space lining. Although rare and is usually symptomless, it is not uncommon for the patients to have some nasal, ear, cervical or oral symptoms. We report a case of Tornwaldt cyst with rare associated dental symptoms. The patient’s initial presentations were dry mouth, cheek biting, post nasal drip and few nasal symptoms including frequent snoring, sleep apnoea, mouth breathing, sneezing, sore throat and itchiness. These symptoms were tremendously and immediately relieved once the cyst was surgically removed.
ABSTRACT
OBJECTIVE:To observe the effect of different concentration of borneol nasal drops on the vasopermeability of nasal mucosa and the cerebral vessels.METHODS:Guinea pigs were divided into5groups,i.e.borneol group in3different concentrations(0.5%,1.0%and2.0%),histamine group and liquid paraffin group.Guinea pigs were injected i.v with2%evans blue(EB)after administration with nasal drops,which were then put to death10min later;the nasal mucosa and brain tissue of which were obtained and the EB contents in which were determined.RESULTS:Compared with the liquid paraffin group,the EB contents in the nasal mucosa and brain tissue in the borneol groups were higher(P
