This report extends these observations by showing that MEE also contains C3 proactivator (C3PA) that can be activated by those organisms involved in acute otitis media, which confirms a functional alternate complement pathway. Furthermore, we have demonstrated the presence of soluble immune complexes in MEE using the Raji cell test.

A bivariate plotting method has been described for predicting hearing loss from reflex threshold data that is characterized by a low rate of false positives, while successfully identifying those with a moderate degree of hearing loss (greater than 32 dB) more than 80% of the time. We found no evidence of decreasing reflex threshold with age. Instead, our reflex thresholds for normal hearing subjects tend to remain the same or increase slightly as age increases. It is hoped that these findings will stimulate further work to correlate reflex thresholds with hearing levels. This information should be used to test infants (especially those at high risk for hearing loss) and other subjects unable to respond to conventional audiometric testing.</p>","PeriodicalId":76762,"journal":{"name":"Transactions.
