The study involved 126 patients with cholelithiasis. Set of biochemical, radiological, endoscopic, and ultrasound examinations was carried out in these patients. Potential coincidence of clinical symptoms and causes of so-called postcholecystectomy syndrome was the purpose of a 1-year follow-up studies. The significance of the results are discussed. 相似文献

Nifedipine was administrated to 25 patients with chronic congestive heart failure treated with digoxin and furosemide++, nifedipine (NF) in a daily dose of 30-80 mg for 14 days. Before and after the treatment with nifedipine chest X-ray, blood biochemical investigations, echocardiographic evaluation of the left ventricular function and submaximal exercise test were performed. Nifedipine induced significant decreases in the left ventricular systolic dimension, heart volume, blood serum potassium and uric acid concentrations and hematocrit . Resting and exertional heart rate, blood pressure, exercise power and duration, watt-pulse, myocardial oxygen demand index, ejection fraction, cardiac output, body weight, 24-hour urinary output, blood serum concentrations of urea, creatinine, sodium and chloride changed insignificantly following nifedipine administration. The obtained results suggest that long-term nifedipine treatment of patients who were already given digoxin and furosemide neither improve nor worsen their clinical status. 相似文献

Monotherapy of hypertension with acebutolol in diabetics in daily dose of 200-400 mg for 6 weeks induced only non-significant and practically not acceptable hypotensive effect in groups of patients with hypertension and diabetes type I or type II without nephropathy. No therapeutical effect was observed in hypertension in diabetics type I with nephropathy. Administration of acebutolol to hypertensive diabetic patients with nephropathy resulted in tendency to increase in albuminuria. Values of creatinine clearance did not change at the same time. Also no effect of acebutolol on glycemic or lipid indices was observed. The lack of clear hypotensive effect under studied conditions of acebutolol in diabetic patients contrasted with its significant action in comparative group of hypertensive non-diabetic subjects. 相似文献

LTABP regimen was applied to 18 patients in IIB and IV stage of malignant lymphogranulomatosis resistant to MOPP. The obtained results were compared with historical control group of 18 patients with similar stage of the disease treated according to ABVD regimen. In both regimens courses were repeated every 28 days or more rarely, when leucopenia and thrombocytopenia prolonged. Only patients who had received at least 3 courses were analysed. In the LTABP group the complete remission was obtained in 10 cases (55%) while partial remission in 6 (33%). In the group treated with ABVD complete remission was obtained in 4 cases (22%) and partial in 9 cases (50%). In the LTABP group 11 patients are still alive and remain in complete remission, while in ABVD group--4 patients. The most frequent side effects in both groups included leucopenia, thrombocytopenia and symptoms of gastrointestinal intolerance. The LTABP regiment allows to obtain higher percentage of the complete remission than ABVD. 相似文献

Methods and results of both conservative and invasive therapy of pericarditis were analysed in the group of 30 patients. An emphasis was on successful treatment of mild (idiopathic) pericarditis and efficiency of the early started, combined pharmacotherapy (tuberculostatics + corticosteroids) of pericarditis of tuberculous etiology. A stress is on marked immediate efficacy of surgery in case of cardiac tamponade, independent on its etiology, with simultaneous recommendation of ultrasound-guided pericardial sac paracentesis. Survival rate in patients with malignant pericarditis is relatively low. 相似文献

Unusual organization of the tropharium in the telotrophic ovarioles of an insect, Saldula saltatoria
The tropharium of the common shorebug Saldula saltatoria consists of 2 zones: the apical mitotic region and the distal one comprising numerous mononucleate nurse cells. Each individual nurse cell is connected to the centrally located trophic core by a thin cytoplasmic projection referred to as a trophic process. The accumulations of a dense material interpreted as the remnants of intercellular bridge rim are observed associated with the trophic process membrane. In the light of these results the establishment of telotrophic ovarioles in hemipterans is discussed. 相似文献

In twenty anaesthetized and spontaneously breathing rabbits airway pressures were measured above and below the larynx during tidal respiration through the larynx. Peak inspiratory and expiratory pressures at both sites were recorded in control conditions and then compared to values obtained in the course of progressive denervation of the airways. The two methods of denervation consisted of (1) bilateral section of superior and recurrent laryngeal nerves and of the midcervical vagotomy (horizontal method); (2) right-sided sections of the three nerves followed by left-sided sections (vertical method). Motor denervation of the larynx due to RLNs neurotomy (horizontal method) produced significant increases in intratracheal pressures in both phases of the respiratory cycle. Less prominent increments in pressures were achieved on RLNs neurotomy in the vertical method. SLNs section and vagotomy had little additional effect on airway pressures. Our results indicate that unilateral laryngeal palsy poses far smaller obstruction to breathing than simultaneous bilateral denervation, and that afferent denervation of the larynx has no effect on airway pressures. 相似文献

The aim of this study was to examine if E. coli isolated from asymptomatic bacteriuria differed in pathogenic features from strains isolated from symptomatic infections of urinary tract. In this study 130 strains of E. coli isolated from women having asymptomatic bacteriuria and 112 strains isolated from patients with symptoms of urinary tract infection were examined. It was shown that E. coli isolated from patients with symptomatic urinary tract infection showed the more frequently ability to cause mannose-resistant haemagglutination of human erythrocytes, resistance to bactericidal activity of serum and haemolytic properties than those isolated from asymptomatic bacteriuria. These strains showed also the higher ability to adhere to Vero cells in tissue culture. Among E. coli strains isolated from persons with asymptomatic bacteriuria the pathogenic features were most frequently found in strains from healthy women and the most rarely in isolated from diabetic women. 相似文献

The risk of offspring with unbalanced karyotypes born to carriers of reciprocal chromosomal translocation (RCT) is important to evaluate for further family planning and prenatal diagnosis. The authors describe two families with carriers of similar RCT concerning breakpoint positions and discuss the different individual risks for abnormal progeny. These translocations were studied by GTG, RBG and CBG banding. They have the same breakpoint on 9p, i.e. 9p22, and a different one on 12p, i.e. terminal (pter----p13) and intermediate (p11.2), respectively. The risk value of 27% for family 1 was obtained directly from the large enough pedigree (high risk) a risk value of about 5% was estimated for family 2, according to the guidelines of Stene and Stengel-Rutkowski (1988). The data show that similar translocations with only slight differences in the breakpoints position have different risks for unbalanced progeny. Results of these empiric findings may be used directly in genetic counselling of a family with RCT leading to a single imbalance of the same segment. 相似文献

Human promyelocytic leukemia cells, HL-60, were treated with cisplatin [cis-diamminedichloroplatinum (II)] (2 mM, 1 h). DNA-cisplatin-protein complexes were isolated and exposed to thiourea (1 M), NaCN (100 mM), diethyldithio-carbamate (500 mM), or N-methyl-D-glucamine dithiocarbamate (500 mM) for 12 h. The release of platinum was measured by atomic absorption spectroscopy. Sodium cyanide was the most effective agent, releasing about 90% of the DNA-bound platinum. Thiourea was the least effective agent, while dithiocarbamates exhibited an intermediate. The ability of the same group of agents to split the proteins off from the protein-cisplatin-DNA complex was also evaluated and similarly dithiocarbamate were also the most effective. 相似文献
