Recurrent urinary tract infections--uropathogen incidence and drug sensitivity.

The aim of the study was the retrospective analysis of the results of the drug sensitivity studies of bacterial species cultured from 681 urinary specimens collected from 79 children (12 boys and 67 girls) aged 0-18 years with recurrent urinary tract infection in a period from 1997 to 2001. Factors predisposing to recurrent urinary tract infections and the incidences of particular uropathogens were also analyzed. Escherichia coli (57.

Efficacy of vaccination against viral hepatitis type B in children with the nephrotic syndrome.

The purpose of the study was to estimate the efficacy of vaccination against viral hepatitis type B in children with the nephrotic syndrome and to estimate the probable cause-effect relationship between the occurrence of the nephrotic syndrome and infectious diseases and vaccination in children. The retrospective study comprised 235 nephrotic children aged 1-14 years hospitalized in the Department of Pediatric Nephrology at University Children Hospital, Lublin, between 1982 and 1997. 56 nephrotic children aged 2-13 years received vaccination against viral hepatitis type B.

Urinary excretion of N-acetyl-beta-D-glucosaminidase and alpha1-microglobulin in children with proliferative blood diseases.

The purpose of the study was to estimate the urinary excretion of NAG and alpha-1M among children who suffer from proliferative blood diseases. The group of the examined children included those who went through a viral hepatitis (VH) and who are or were treated by means of cytostatic drugs. The study comprised 73 children aged from 4 to 18 (average 11.

[Anatomic and functional disorders of the urinary tract in children with urinary tract infections].

The study is based on clinical analysis of 207 case recordings of children with urinary tract infection (UTI) hospitalized in The Department of Pediatric Nephrology, University Hospital, Lublin in 1995-1999. The study comprised children aged 1-18 years, average 8.8 +/- 0.

[Health status and physical development of children delivered by mothers who suffered from nephrotic syndrome in their infancy].

Numerous complications of nephrotic syndrome due to either the illness itself or repeated courses of high-dose corticosteroids have been well recognised for several score years. However, investigations concerning children of ex-patients are lacking. The purpose of this study was to assess physical development and health state in the group of children whose mothers had suffered from the idiopathic nephrotic syndrome during their childhood.

ABR differences before and after dialyses.

The aim of the study was the objective evaluation of the hearing organ in children. Seven children aged 6-17 with end stage renal failure treated by haemodialysis were examined. Four- to five-hour dialyses were performed 2-3 times a week.

Role of some biogenic amines in the pathomechanism of glomerulonephritis. I. Histological examinations of kidneys in acute and chronic serum sickness in rabbits.

Investigations were carried out on the role of biogenic amines in the development of glomerulonephritis in rabbits using the experimental model of acute and chronic serum sickness. The animals immunized with foreign-species albumin received additionally 5HT and some of them were given reserpine or PCPA for reducing the level of biogenic amines. The results of histological examinations demonstrated a clear cut inhibitory effect of PCPA and reserpine on the development of inflammatory changes in the glomeruli, and their intensification with simultaneous 5HT administration.

Role of some biogenic amines in the pathomechanism of glomerulonephritis.

Investigations were carried out on the patterns of adrenaline (A), noradrenaline (NA), 5-hydroxytryptamine (5HT) and 5-hydroxyindole-acetic acid (5HIAA) in chronic serum sickness produced in rabbits by repeated subcutaneous administration of bovine albumin. In some animals serotonin or parachlorophenylalanine (PCPA) were given additionally. Long-term immunization lasting 5-8 weeks caused a significant rise in NA excretion in the first 3 weeks of the experiment, and a less evident fall in the 5HT level in the blood, and 5HT, 5HIAA and A in urine.

Role of some biogenic amines in the pathomechanism of glomerulonephritis. II. Adrenaline, noradrenaline and serotonin in acute serum sickness in rabbits.

In acute serum sickness induced with one intravenous dose of bovine serum albumin (BSA) in 40 rabbits the patterns of excretion of adrenaline (A), noradrenaline (NA), serotonin (5HT) and 5-hydroxyindole-acetic acid (5HIAA) were studied in 24-hour urine, and the 5HT level was determined at intervals of three days. The urinary levels of biogenic amines were determined daily. Some rabbits immunized with BSA received also additionally 5HT, reserpine or parachlorphenylalanine (PCPA).

The role of serotonin in Masugi nephritis in rabbits.

In 12 rabbits with induced experimental Masugi nephritis and in 6 control rabbits the level of 5-HT in whole blood and 5-HIAA excretion in urine/24 h were studied. In all animals of the experimental group a significant increase of 5-HT and 5-HIAA was found, which was strictly correlated in time with two-phase immunological reaction occurring in Masugi nephritis. Moreover, the electorn microscope examinations showed a distinct thickening of glomerular basement membrane on the 8th day of experiment, i.
