Histomorphological changes in thymus and spleen after cyclooxygenase inhibitors treatment
The influence of cyclooxygenase inhibitors on the lymphoid organs histomorphology has been examined in the matured outbread white mice. Diclofenac, meloxicam, celecoxib, but not rofecoxib has shown depressive action on the im-munocompetetive organs histomorphologic structure. Macroscopic study has r...

The influence of cyclooxygenase inhibitors on the lymphoid organs histomorphology has been examined in the matured outbread white mice. Diclofenac, meloxicam, celecoxib, but not rofecoxib has shown depressive action on the im-munocompetetive organs histomorphologic structure. Macroscopic study has revealed a decrease in the weight of the spleen and thymus. Light microscopy has shown a decrease in the number of thymocytes, due to degradation of cortex area. In the lobular medulla it has been observed microcirculation changes in the view of venules and capillaries distention, arteriolar wall thickening. In the spleen it has been shown a decrease in the white pulp volume, disappearing of the reactive centers in follicles.
