Abstract
OBJECTIVE
The objective of this study was to perform a histopathological, morphometric and proteomic study of the parotid gland of dogs naturally infected with Leishmania infantum treated and not treated with Allopurinol.
DESIGN
Parotid glands from 14 dogs were used, divided into two groups: untreated and treated with oral allopurinol (20 mg / kg, once daily for 90 days). After adequate dissection, the organs were submitted to histopathological, histomorphometric and immunohistochemical techniques, using the monoclonal anti-β-catenin antibody.
RESULTS
Histopathological evaluation of treated and untreated groups showed acinar hypertrophy, structural disorganization of the nucleus and cytoplasm. There was an increase in the area and perimeter of the parotid acini in the experimental groups. The immunostaining of the β-catenin protein in the membrane was severely reduced in the treated and untreated groups.
CONCLUSIONS
These findings suggest that Leishmania infantum infection and treatment with Allopurinol alter the tissue structure of the parotid gland in dogs, promoting an increase in the acinar volume and a decrease in the expression of β-catenin in cell membranes.
