[Abdominal pain syndrome and quality of life in patients with cholelithiasis after cholecystectomy during a 10-year follow-up]. / Abdominal'nyi bolevoi sindrom i kachestvo zhizni u bol'nykh zhelchnokamennoi bolezn'yu posle kholetsistektomii pri 10-letnem nablyudenii.

AIM: To estimate the incidence of abdominal pain syndrome (APS) and to assess quality of life (QOL) in patients within 10 years after cholecystectomy (CE). SUBJECTS AND METHODS: This investigation is part of a long-term prospective follow-up study of patients after CE for cholelithiasis (CL). It enrolled 145 people: 30 (21.5%) patients with baseline asymptomatic CL and 115 (80.7%) with its clinical manifestations. The time course of changes in APS and QOL were analyzed. RESULTS: Over 10 years, all the patients showed a decrease in the incidence of APS from 84.1% (n=95) to 66.4% (n=75; p=0.004). In Group 1 (n=89), APS was at baseline detected in all the patients; 10 years later, its incidence declined to 67.4% (n=60; p < 0.001). Biliary pains were predominant; these had been identified significantly less frequently over the 10-year period in 47 (52.8%) patients; p<0.001). In Group 2 (n=24), pre-CE APS was generally detected in 6 (25%) patients; following 10 years, the incidence rates of pain significantly increased to 62.5% (n=15; p=0.035), among which there were predominant biliary pains (in 54.2%; p<0.001) and dyspepsia from 33.3% (n=8) up to 66.7% (n=16; p=0.039). QOL in the physical and mental health domains was found to decrease in both groups. CONCLUSION: Ten years after CE, the group with the baseline clinical manifestations of CL and poorer QOL showed a lower incidence of APS mainly due to the reduced incidence of biliary pains and the baseline asymptomatic group exhibited a rise in the incidence of APS due to the appearance of biliary pains and dyspepsia.

[The detection of medication sensitivity of M.tuberculosis isolated from patients with tuberculosis with multiple medication resistance in testsystem "Sensititre MycoTB".]

The test-system "Sensititre MycoTB" was applied to analyze 159 cultures of M.tuberculosis isolated from patients with tuberculosis. According data of investigation in "Bactec 960" they are identified as cultures with multiple medicinal sensitivity. The detailed analysis of results of application of mentioned test-system (mycoTB) demonstrated that significant part of cultures with multiple medicinal sensitivity is sensitive to anti-tuberculosis pharmaceuticals. The significant part of cultures is characterized by "intermediate" sensitivity/resistance than can be established by mentioned test-system. This data permits enlarging possibilities of chemotherapy of tuberculosis.

THE FREQUENCY OF DYSPEPTIC DISORDERS FOLLOWING CHOLECYSTECTOMY PATIENTS ACCORDING TO THE 10-YEAR STUDY.

AIM: To evaluate gastrointestinal symptoms during 10 years after cholecystectomy in patients with symptomatic and asymptomatic gallstone disease and to identify predictors of them. MATERIALS AND METHODS: The work is the part of a prospective long-term monitoring of patients with symptomatic (1) and asymptomatic (2) gallstone disease after cholecystectomy (CE). The study included 145 patients: 115 (80.7%) with initially symptomatic disease (1) and 30(21.5%) asymptomatic (2) disease. RESULTS: The frequency of heartburn increased from 15.9% to 63.7% during 10 years (p = 0.015) after CE especially in the group (1) (from 2.24% to 68.53% (p 0.037). The frequency of "bitter taste in the mouth" raised from 46.9% before the CE to 69.02% after CE (p < 0.001). The frequency of diarrhea increased from 0.88% to 38.2% in both groups. (p = 0.046). CONCLUSION: The frequency of heartburn, "bitter taste in the mouth", diarrhea increased in patients after 10 years in patients with symptomatic and asymptomatic gallstone disease after CE. A common risk factors are presence symptomps at baseline and the presence of these symptoms at the 6rst years after CE.

[Biophysical parameters of erythrocyte membranes and mechanisms of interaction with non-opioid analgesics under acute pain syndrome].

Methods of fluorescent probing, spectrophotometry and microcalorimetry were applied to investigate the alterations in biophysical parameters of erythrocytes membranes, and specifically microviscosity, surface charge, molecular organization of lipid bilayer and lipid-protein interactions under conditions of acute pain syndrome produced by experimental chemical lesion. The distinctive features of non-opiod analgesics interactions and binding to the erythrocytes membranes of rats subjected to acute nociceptive pain accompanied with oxidative stress development were investigated. The abilities of analgesics under research, and namely paracetamol, aspirin, phenazone, ketorolac, pyrodazole, ketoprofenum, natrium mefenaminate, indometacin, nimesulide to make up physico-chemical complexes with lipoperoxidation modified erythrocytes surface and protein-lipid bilayer showed marked changes. The significance of oxidative damage of biophase under conditions of acute pain syndrome for analgesics effective pharmacodynamics and pharmacokinetics realization is under consideration.

[Long-term dynamics of gastrointestinal symptoms after cholecystectomy for the treatment of cholelithiasis].

The aim of the work was to analyse dynamics of gastrointestinal symptoms and risk factors at different periods after cholecystectomy (CCE) in patients with cholelithiasis (CL). It was a prospective open cohort observational study with interviewing the patients before, 6 and 36 months after cholecystectomy for the treatment of CL. The pain symptom of CL persisted in 65.9% of the patients till the 6th month after CCE and in 57.3% of the patients till the 36th month. The logistic univariant analysis showed high probability of persistence and/or appearance of biliary pain within 6 months after surgery in patients suffering biliary colic before it (OR = 5.3, p = 0.01) and having hereditary aggravation of CL (OR = 2.7, p = 0.38). The relationship between biliary pain and planned surgical intervention for the treatment of CL was documented 3 years after the operation (OR = 2.6, p = 0.018). Similar relationship was revealed after 6 and 36 months (OR = 3.8, p = 0.002). Biliary pain within 6 months after CL was an independent prognostic factor of its development within the next 3 years. Other increasingly severe gastrointestinal symptoms were heartburn, intolerance of greasy food, and disturbed intestinal passage as a result of biliary insufficiency or disordered intestinal motility. The above relationships between gastrointestinal symptoms may be used to predict their appearance within 6 months after CL.

[Antioxidant and cerebroprotective action of N-,S-chinazolone derivative under rat brain ischemia].

Under modelling of brain ischemia in rats the antioxidant and cerebroprotective action of new N-,S-chinazolone derivative--compound NC-224 has been established. The compensation of pathobiochemical abnormalities in the system "LPO-antioxidant protection" is observed, indicators of carbohydrate metabolism and energy-supply, and morpho-functional status of brain cells are improved under administration of the compound NC-224. Administration of the compound NC-224 to rats promoted a decrease of the lethality index and signs of neurological deficiency.

These results have shown a necessity of complex evaluation of antioxidant properties of pharmacological drugs.

[Changes of immune and non-specific reactivity in patients with chronic suppurative obstructive bronchitis in comprehensive treatment with thymogen]. / Izmeneniia immunologicheskoi i nespetsificheskoi reaktivnosti u bolnykh khronicheskim gnoino-obstruktivnym bronkhitom pri kompleksnom lechenii s primeneniem timogena.

A total of 33 patients with chronic pyoobstructive bronchitis with immunological disorders (of T-cell and other links) and nonspecific responsiveness. The use of thymogen in multi-modality treatment contributed to normalization of T-cell immunity (increases in E-rosette formation, responses of blast cell transformation to phytohemagglutinin, Tx/Tc ratio), as well as nonspecific responsiveness parameters (C3c, NBT-test, natural killers), resulting in higher clinical efficacy.

[Lipid peroxidation and calcium transport in rat liver microsomes after chlorofos poisoning and the effect of atropine and verapamil]. / Perekisnoe okislenie lipidov i transport Ca2+ v mikrosomakh pecheni krys pri intoksikatsii khlorofosom i deistvii atropina i verapamila.

Structural and functional state of rat hepatocytes endoplasmic reticulum membranes intoxicated with chlorofos (0,0-dimethyl-(1-oxy-2,2,21-trichloroethylphosphonate) was studied. It was shown that in case of intoxication a breakage of the membrane Ca(2+)-transport function was accompanied by modification of the membrane phospholipid lipoperoxidation processes and by conformational change of proteins. It is established that prophylactic injection of m-cholinolytic atropine and Ca(2+)-channel antagonist verapamil lead to normalization of processes of ATP-dependent potassium ion transport and lipid peroxidation processes (LPO) in the liver microsomal membranes of intoxicated animals.

[Immunologic and non-specific reactivity in patients with chronic suppurative obstructive bronchitis and its effect on the course of disease]. / Immunologicheskaia i nespetsificheskaia reaktivnost bolnykh khronicheskim gnoino-obstruktivnym bronkhitom i eë vliianie na techenie zabolevaniia.

A total of 32 patients with aggravated chronic pyo-obstructive bronchitis were studied. Various immunological disorders and impaired non-specific responsiveness were detected in this group of patients. With this, abnormal T cellular immunity (reduced T cell counts at the expense of T helpers and their reaction to PGA) was the leading T cell immunity disorder. In the presence of the available immunity abnormalities, responses to inflammation (B-systems) and non-specific responsiveness were less pronounced. During treatment, the patients without substantial immunity disorders had normalized parameters of immunity and non-specific responsiveness, whereas the patients displayed this. The clinical efficacy of treatment was higher in patients without significant abnormalities in immunity and non-specific responsiveness.

[Peroxide modification of membranes and isomorphic composition of cytochrome P-450 of rat liver microsomes during antioxidant deficiency]. / Perekisnaia modifikatsiia membran i izomorfnyi sostav tsitokhroma P-450 mikrosom pecheni krys v usloviiakh antioksidantnoi nedostatochnosti.

Lipid peroxidation (LPO), physico-chemical properties of the membranes and isoformic composition of microsomal cytochrome P-450 from the rat liver were studied under conditions of antioxidant insufficiency (AOI) which was modelled by exclusion of alpha-tocopherol from the animals' ration. An insignificant accumulation of microsomal diene conjugates and schiff bases against a sharp increase of the ability to the prooxidant stimulated LPO in vitro took place. A significant decrease of membrane lipid microviscosity and a change in surface properties of microsomal membranes of rats with AOI was determined. Absence of alpha-tocopherol in the ration was accompanied by a significant change in the content of separate isoforms of cytochrome P-450 exhibited in growth of a polypeptide with m. w. 54 kDa and the lowering of proteins with m. w. 48 and 50 kDa. Less intensive quenching of tryptophan fluorescence by acrylamide was also revealed, which testified to a lower accessibility of the quencher to membrane proteins or their fluorophore sites. Modification of lipid composition and of physicochemical properties of the rat liver membrane microsomes which was observed at AOI was significantly correlated by pretreatment with the antioxidant 4-methyl-2,6-ditretbutylphenol (ionol).
