Trichophytin extraction: biological comparison of trichophytin extracted from Trichophyton mentagrophytes grown in a complex medium and a defined medium.
The extraction of antigens (trichophytin) from Trichophyton mentagrophytes var. asteroides grown in both a complex medium and a defined medium proved to be reproducible and feasible. These extracts were first evaluated by skin testing in both infected and noninfected guinea pigs. Further evaluation and standardization was accomplished in selected humans by comparing these antigens to a trichophytin known to elicit allergic reactions to the dermatophytes. The trichophytins produced by this extraction procedure gave no false positive (or negative) skin test reactions. These antigens did, however, reliably elicit allergic sensitivity of both the immediate and delayed type. The potency of both complex and defined media antigen was shown to be equal to that of the standard trichophytin.

Laboratory services for psychiatric facilities.
The science and marketing of psychiatric treatment are rapidly changing, and the changes are reflected, in part, in the recent evolution of the use of laboratory services. Nevertheless, there are few, if any, articles in the literature addressing how a laboratory service can best assist a psychiatric hospital. This article presents a scaffolding of current issues to be considered when determining how a laboratory can assist the psychiatric facility. It cites the special laboratory needs of the psychiatric hospital and issues to be considered when evaluating laboratory service.
