[Pathomorphologic and hematologic studies of the immunotoxicity of the phenoxyalkane acid mecoprop in rats].

For a first estimation of the influence of the as herbicide used phenoxy acid Mecoprop on the immune system pathomorphological and haematological investigations were carried out. Histological results are completed by results of morphometrical--stereological investigations. Mecoprop causes structural changes in spleen and thymus and changes of the number of blood lymphocytes and granulocytes. The possibility, that the effects are induced by chemical stress, is discussed.
