Anti Inflammatory

Ketoprofen, a nonsteroidal anti-inflammatory drug (NSAID) has proven to exert anti-inflammatory, anti-proliferative and anti-angiogenic activities in both neoplastic and non-neoplastic conditions. We investigated the effects of this compound on tumor development in Swiss mice previously inoculated with Ehrlich tumor cells. To carry out this study the solid tumor was obtained from cells of the ascites fluid of Ehrlich tumor re-suspended in physiological saline to give 2.5x106cells in 0.05mL. After tumor inoculation, the animals were separated into two groups (n = 10). The animals treated with ketoprofen 0.1µg/100µL/animal were injected intraperitoneally at intervals of 24h for 10 consecutive days. Animals from the control group received saline. At the end of the experiment the mice were killed and the tumor removed. We analyzed tumor growth, histomorphological and immunohistochemical characteristics for CDC47 (cellular proliferation marker) and for CD31 (blood vessel marker). Animals treated with the ketoprofen 0.1µg/100µL/animal showed lower tumor growth. The treatment did not significantly influence the size of the areas of cancer, inflammation, necrosis and hemorrhage. Moreover, lower rates of tumor cell proliferation were observed in animals treated with ketoprofen compared with the untreated control group. The participation of ketoprofen in controlling tumor malignant cell proliferation would open prospects for its use in clinical and antineoplasic therapy.

Ehrlich Tumor Cells

The Ehrlich tumor is a mammary adenocarcinoma of mice that can be developed in solid and ascitic forms depending on its administration in tissues or cavities, respectively. The present study investigates whether the subcutaneous plantar administration of the Ehrlich tumor cells induces pain-like behavior and initial pharmacological susceptibility characteristics. The Ehrlich tumor cells (1 × 104–107cells) induced dose-dependent mechanical hyperalgesia (electronic version of the von Frey filaments), paw edema/tumor growth (caliper), and flinches compared with the saline group between days 2 and 12. There was no difference between doses of cells regarding thermal hyperalgesia in the hot-plate test. Indomethacin (a cyclooxygenase inhibitor) and amitriptyline hydrochloride (a tricyclic antidepressant) treatments did not affect flinches or thermal and mechanical hyperalgesia. On the other hand, morphine (an opioid) inhibited the flinch behavior and the thermal and mechanical hyperalgesia. These effects of morphine on pain-like behavior were prevented by naloxone (an opioid receptor antagonist) treatment. None of the treatments affected paw edema/tumor growth. The results showed that, in addition to tumor growth, administration of the Ehrlich tumor cells may represent a novel model for the study of cancer pain, specially the pain that is susceptible to treatment with opioids, but not to cyclooxygenase inhibitor or to tricyclic antidepressant.
