[The differential assessment of the state of lipid peroxidation and of the antioxidant system in patients in the late period after gastric resection]. / Dyferentsiiovana otsinka stanu perekysnoho okyslennia lipidiv ta antyoksydantnoï systemy u khvorykh u viddalenomu periodi pislia rezektsiï shlunka.

Studied after stomach resection for ulcer disease in 161 patients were lipid peroxidation (LPO), antioxidant system (AOS) and related parameters characterizing metabolism of carbon (Lactat), protein (piruvat) and fat (fat acids, lipoproteins), an indicator of the dystrophic change degree (acid phosphatase). Revealed in these patients was syndrome of peroxidation, which leads to disturbances of protein, carbon and fat metabolism, destruction of cell membranes. Increased, "normal", weakened LPO was identified in 67.7%, 9.94%, 22.36% of the patients respectively. In patients with an increased LPO statistically significant activation of AOS was established, lactate having increased more than twice, pyruvate remaining unchanged; the level of fat acids and lipoproteins almost doubled. In such a situation it is reasonable to use preparations which activate aerobic glycolysis, and antioxidants of a direct, mild degree, action. In group II patients with more prominent increase in the acid phosphatase activity preference should be given to membrane-stabilizing preparations. In patients with a decreased level of LPO considerable increase in lactate and acid phosphatase was noted. It is recommended that preparations promoting normalization of carbon and lipid metabolism, enhancement of redox processes in the respiratory chain should be included into complex therapy as should be stabilizers of membranes of cell organelles, with biogenic stimulators to follow.

Complex examination of 73 patients with ulcer disease (bulbus duodeni location) revealed regularities of evacuation of a test breakfast from the stomach depending on the phase of the disease. Significant disorders of the motor-emptying gastric and duodenal function were found that are to be considered in the treatment of this category of patients.

[Ultrasonography of the abdominal cavity organs in peptic ulcer patients following gastric resection]. / Ul'trasonografiia organov briushnoi polosti u bol'nykh iazvennoi bolezn'iu posle rezektsii zheludka.

A study of 205 patients in the follow-up period after gastric resection for ulcer disease indicates that ultrasonography is a valuable method of diagnosis of involvement of the abdominal cavity organs but requires perfection of methods directed at improvement of visualization of the scanned organs. For diagnosis of diffuse lesions of the liver it is rational to combine ultra-sonography with radionuclide, endoscopic and roentgenological methods. It was found that patients with gastric resection syndromes, calculosis of the gallbladder was present in 17.1% while lesions of the pancreas were 4 times more frequent than in the common population.
