Alteration of rodlet cells in chub caused by the herbicide Stam® M‐4 (Propanil)

Abstract

Handling stress and exposure to the herbicide Stam® M‐4 (Propanil) were associated with an exponential depletion of the rodlet cells (RC) in the bulbus arteriosus of chub Leuciscus cephalus . Structural changes of the RC in herbicide‐exposed fish were encountered, including the occurrence of myeloid bodies in the cytoplasm of the RC of the intestine, various degrees of rodlet degeneration and high vacuolization in the cytoplasm of RC in almost all examined organs of exposed chub.
