Impact of the mental healthcare delivery system on california emergency departments.

Introduction: This is an observational study of emergency departments (ED) in California to identify factors related to the magnitude of ED utilization by patients with mental health needs.

Methods: In 2010, an online survey was administered to ED directors in California querying them about factors related to the evaluation, timeliness to appropriate psychiatric treatment, and disposition of patients presenting to EDs with psychiatric complaints.

Results: One hundred twenty-three ED directors from 42 of California's 58 counties responded to the survey.

Clinical manifestations and leukocyte neurotoxic esterase and red blood cell and plasma acetylcholinesterase activities in swine following a single oral dose of tri-o-cresyl phosphate.

We report the clinical signs and the effects on leukocyte neurotoxic esterase and red blood cell and plasma acetylcholinesterase (AChE) activities in swine orally administered a single dose of tri-o-cresyl phosphate (TOCP) at 400, 800 or 1000 mg/kg. Swine in all dosage groups exhibited signs consistent with inhibition of nervous tissue cholinesterase 3-48 h after TOCP administration. Onset was dose-related, and 2/3 1000 mg/kg dosed swine died 3 or 35 h postdosing.

Rabbit pasteurellosis: respiratory and renal pathology of control and immunized rabbits after challenge with Pasteurella multocida.

Gross and microscopic lesions of pasteurellosis were studied in control and immunized pasteurella-free rabbits after challenge with virulent Pasteurella multocida. Pathologic responses were compared in rabbits immunized intravenously or mucosally with P. multocida or with J5, a cross protective core LPS mutant of E.
