Physiologic alterations in the murine model after nasal fungal antigenic exposure.

Objective: To determine whether a recently developed murine model of fungus-induced sinonasal inflammation demonstrated alterations in ciliary activity and expression of inflammatory cytokines.

Study Design: A prospective randomized controlled study of rhinosinusitis after fungal antigenic sensitization was performed with intraperitoneal aspergillus antigen injection followed by intranasal antigen challenge for 4 weeks. Saline solution was used in a parallel fashion for control animals.

Evaluation of rapid staining techniques for cytologic diagnosis of intracranial lesions.

Objective: To evaluate 4 rapid supravital stains and 3 preparation techniques for use in the intraoperative diagnosis of intracranial lesions.

Animals: 10 dogs and 1 cat euthanatized for intracranial lesions.

Procedure: Specimens were taken from lesions and slides prepared, using 3 techniques: touch impression, medium-pressure impression, or smear preparation.
