Pathological Anatomy Of Reparative Processes In The Resected Kidney Treated With α-tocopherol Acetate In Experiment
Violation of the integrity of the kidney parenchyma during organ-preserving surgery is always accompanied by functional impairment in that part of the organ. This is due to mechanical damage to the nephron and the development of aseptic necrosis in the area of the resection, followed by development of an ischemic zone that expands during the repair process due to disrupted parenchymal cell metabolism and pressure from regenerating connective tissue. Objective. To investigate the effect of α-tocopherol acetate on repair processes in the kidney parenchyma after an organ-preserving operation in a rat model. Materials and methods. An experimental study was performed on 60 white laboratory rats that underwent resection of the lower pole of the left kidney. Postoperatively, a study group (n = 30) underwent intramuscular injections of a 10% α-tocopherol acetate oil solution, 0.2 ml 2 times a day for 5 days. A control group (n = 30) were left untreated. Results. Compared with the control group, animals in the study group had a narrower zone of total necrosis and less pronounced inflammation and vascular stasis on days 7, 14, and 28 after the operation. Conclusion. Use of the natural antioxidant α-tocopherol acetate in the postoperative period of organ-preserving kidney surgery may accelerate reparative processes in the damaged parenchyma.
