Effect of carboplatin on malondialdehyde as a marker of lipoderoxidation in the submandibular gland of rats

Witar rats, carboplatin, malondialdehyde, submandibular glandAbstract
The objective of the present work was to evaluate the effect of carboplatin (Cp) on submandibular gland homogenate of Wistar rats through the determination of malondialdehyde levels, as the main end product of lipoperoxidation, in an experimental model. Sixteen three-month-old male Wistar rats were used, housed in individual cages, with controlled temperature and lighting and free diet. A completely randomized design was used and two experimental groups were established: 1) Control (C), administering an intraperitoneal dose of saline solution for one day, n: 8, 2) Animals treated with carboplatin (Cp) applying a dose i.p. of 100 mg / Kg of body weight for one day, n: 8. The animals were fasted for 24 hours and subsequently anesthetized. Then both submandibular glands were removed. Malondialdehyde levels were analyzed in submandibular gland homogenate in both experimental groups. Variations between the groups analyzed were evaluated using the Student's t test for paired samples, setting a p-value <0.05 for statistical significance. Project approved by CICUAL. Faculty of Medical Sciences (UNC). The group of Rats C o showed a concentration of 7.32 ± 0.48 µmol / mg of gland. The Cp group had a concentration of 12.57 ± 0.71 µmol / mg of gland, expressing a significant decrease compared to the control group p <0.0006. Cp at the dose tested would cause a decrease in lipoperoxidation in the submandibular gland of rats. Possibly the glandular antioxidant battery would neutralize the oxidative stress of acinar cells. These results suggest a future evaluation of superoxide dismutase (SOD) activity and uric acid (UA) levels
