Hematological Profile Of Rats In Experimental Diclofenac-induced Hepatitis


V.А. Gryshchenko

Sodium diclophenac belongs to a group of nonsteroidal anti-inflammatory drugs, which is indicated for inflammatory, degenerative and traumatic lesions system of the skeleton, muscles and connectives tissues. The features of changes in hematological (above all, morphological) indices in Wistar line rats for experimental reproduction of toxic hepatitis at oral introduction of diclofenac sodium in a dose of 12.5 mg / kg of body weight (once a day, within 14 days) were investigated. This rats demonstrated the development of chronic inflammatory process in liver that was characterized by reactive leukocytosis (an increase in the number of leukocytes by a factor of 3), neutrophil right shift, monocytopenia (a decrease in the number of monocytes by a factor of 2.6) together with compensatory lymphocytosis, high values of ESR (by a factor of 5.5), and thymol test (by a factor of 2.9). However, erythrocytopenia (a decrease in the number of erythrocytes by 44 %) – which is a sign of anemia development – was revealed in animals under the experimental toxic hepatitis. Besides it, the hemoglobin content was in the range of normal values that was an evidence of a compensatory role of red bone marrow in the maintaining homeostasis of the respiratory function of blood. There were no changes in blood rheology that was indicated by definite stability of the hematocrit value in sick animals. We registered the development of chronic inflammatory process and anemia in rats caused by experimental reproduction of toxic liver damage by oral introduction of sodium diclofenac.
