HISTOPATHOLOGICAL ANALYSIS OF RENAL EPITHELIUM IN MICE EXPOSED TO INHALATION OF THE HERBICIDE 2,4 DICHLOROPHENOXYACETIC ACID.
Abstract
One of the most widely used herbicides in Brazil, 2,4-dichlorophenoxyacetic acid (2,4-D), has a hazardous grade III. Its excretion is mainly renal, which can cause damage to this system. The objective of the present study was to evaluate the possible histopathological changes in Swiss mouse kidneys caused by exposure to 2,4-dichlorophenoxyacetic acid. For the experiment were used 80 male adult Swiss mice divided into groups, which were then exposed to the herbicide. After euthanasia and autopsy, the kidneys were removed and histologically analyzed. The results obtained from the statistical analysis of the tubular area and renal lumen area, together with previously published studies, have shown that there is little scientific evidence showing inflammatory and/or mutagenic potential of acute exposure to 2,4-dichlorophenoxyacetic acid, however, changes can may exist due to chronic exposure to the herbicide, so further research is needed for further clarification and decision making.
