Seasonal variation of mast cell function in human adenoid tissues.
The number of mast cells which can be recovered from human adenoid tissues varies characteristically in the course of the year. The yield was found to be highest in May and lowest in July. The average histamine content was above average in April, June, July and September. Although the spontaneous histamine release remained relatively constant, the concanavalin A-stimulated histamine release was significantly reduced from June to September.
