The purpose of this paper is to compare two fields of research related to school reform: professional development and educational policy. A content analysis of the literature in both fields revealed two areas where they align (i.e., a focus on teachers' professional development and the idea that change takes time) as well as two areas where there are differences (i.e., theoretical grounding of each field and planning for teachers' learning). Considerations for successful school reform are suggested.

A method for testing the sterility of large, gentamicin-containing, egg phosphatidylcholine (EPC) liposome suspensions is described. The method consists of diluting the liposome formulation in four volumes of 1.5% triton X-I00 (final EPC concentration in the detergent solution is approximately I0 mg/ml) and then filtering the cloudy suspension as outlined by the USP for the membrane filtration sterility test. The method was not bacteriocidal or fungicidal for the organisms tested.
