In vivo Action of Phytohæmagglutinin in Severe Human Aplastic Anæmia

Abstract

PHYTOHÆMAGGLUTININ, an extract containing mucoprotein obtained from the bean, Phaseolus vulgaris, has been shown to cause active transformation of lymphocytes in human peripheral blood tissue cultures. These cells enlarge, actively synthesize DNA and then show considerable mitotic activity1,2. However, injection of the Difco M form of phytohæmagglutinin by various routes into young female Wistar rats did not produce unequivocal evidence of lymphoproliferation3.
