Estimation of phospholipase A2 [PLA2]. Protaglandin E2 [PGE2] cyclic amp [CAMP]. interferon - Y [IFN - Y] and soluble interleukin - 2 receptor [SiL - 2 R] levels in middle ear effusion

ABSTRACT

Levels of PLA[2]. PGE[2]. CAMP, IFN-omega and SIL-2R were estimated in middle ear effusions from 32 patients suffering from otitis media with effusion. They were 19 patients with mucoid type effusion and 13 with serous type. All parameters estimated showed significant increase in cases with mucoid effusion except level of IFN-omega which was significantly increased in the serous type and we suggested that both serous and mucoid types of otitis media with effusion may have different immunological background:
