Impact of surgery is examined in individuals with combined stenotic-occlusive lesions of extracranial and femoralpopliteal-tibial arteries to determine its effects on functional recovery and quality of life. A 50-patient prospective cohort study. Men made up 92% of patients. The age distribution between 51 and 70 suggests a demographic background for surgical procedures, however caution is advised. Surgery frequency shows that bypass surgery is 40% common and that angioplasty, angioplasty with stent, and endarterectomy are versatile. After surgery, quality of life improved statistically, demonstrating the efficacy of therapies beyond functional recovery. While weariness during exercise varied, the overall beneficial outcomes suggest that surgical procedures can improve the lives of vascular disease patients. The findings enrich treatment plans and improve knowledge of subtle outcomes in functional recovery and QOL for doctors, researchers, and patients.

Modern aspects of the pathogenesis of acute inflammation of the peritoneum that is concurrent with diabetes involves analysis of metabolic mechanisms, in particular peroxidaton of proteins – antioxidant defense. Therefore, the objective of our study was to examine the interrelation between the processes of free-radical oxidation of proteins and antioxidant system in the dynamics of development of acute generalized peritonitis against the background of streptozotocin-induced diabetes. The study was performed on 56 non-linear white mature male rats. Diabetes mellitus was modeled by a single intraperitoneal injection of streptozotocin (60 mg/kg). On the 14th day of the development of streptozotocin-induced diabetes, we injected 10% filtrated faeces suspension (0.5 mL) into the abdominal cavity, thus initiating acute generalized peritonitis. Oxidative modification of proteins in blood serum was studied using the I. F. Meshchyshen’s method and the condition of antioxidant protection was monitored according to the activities of superoxide dismutase, catalase, content of reduced glutathione, and the level of ceruloplasmin.
The study of the parameters of free-radical oxidation of proteins and study of the condition of antioxidant system in
blood of the rats with experimental acute generalized peritonitis against the background of streptozotocin-induced diabetes demonstrated that oxidative protein modification grew, while the parameters of the activity of antioxidant system were being inhibited, depending on the stage of acute inflammation of the peritoneum. We determined inverse correlation relationships between the products of free-radical oxidation of proteins and parameters of antioxidant system on the third and on the seventh days of modelling of combined pathology. Manifestation of acute generalized peritonitis concurring with streptozotocin-induced diabetes was accompanied by a gradual accumulation of the products of free-radical oxidation of proteins and exhaustion of the antioxidant defense during all stages of the development of acute inflammation of the peritoneum, peaking on the seventh day after administration of faecal suspension (terminal stage of peritonitis). The observed inverse correlations between the levels of oxidative modification of proteins and the activity of superoxide dismutase, catalase, reduced glutathione, and ceruloplasmin on
the third and on the seventh days of modelling of combined pathology indicate a predictive role of the processes of free-radical oxidation of proteins in exhaustion of antioxidant-defense resources.
