A quantitative estimation of the depletion of the granules of argyrophile cells in the gastrointestinal tract of reserpine treated Rhesus monkeys.

The depletion of the granules of argyrophile cells following administration of reserpine has been studied at various levels of the gastrointestinal tract of the Rhesus monkey. Granulation of the cells has been estimated by the photometric method of SINGH(1976). The argyrophile cells that persist after reserpine administration show a statistically significant reduction in their granulation as compared to cells of untreated controls (P less than 0.001).
