    Notes: Summary: IgA nephropathy is a clinically and histologically defined syndrome of unknown aetiology, which may have various causes in different parts of the world. Immunologically it is characterized by deposition of IgA1, probably polymeric IgA, in the mesangium and is frequently associated with IgG, C3 and components of the alternative pathway of the complement cascade. the disease can go into complete remission in children, but in adults it usually has a progressive course, characterized by the appearance of proteinuria and hypertension and loss of glomerular filtration rate (GFR). Histologically the development of glomerulosclerosis and tubulo-interstitial changes correlate with a clinical progressive course. the mucosal immune system is characterized by high plasma IgAl antibody responses after parenteral immunization with viral or bacterial vaccines. However, following nasal challenge with a bacterial neoantigen, IgA nephropathy patients appear to have a defective mucosal immune response in their nasal washes, in their bone marrow and in their plasma IgA1 antibody levels.

    Notes: Summary: Although a genetic predisposition to IgA nephropathy can be documented in a minority of patients, the majority of cases are sporadic. The frequent association with mucosal infections suggest the aetiologic involvement of microbial antigens. However, no particular bacterial or viral strain has clearly been implicated. The involvement of mesangial or endothelial autoantigens has been suggested but not proven in a majority of cases. Most patients have a significantly higher memory repertoire of IgA forming B-lymphocytes in their bone marrow associated with high plasma levels of IgA1 while the mucosally stimulated IgA response against recall antigens is augmented, the mucosal and plasma IgA response after mucosal stimulation by neoantigen is significantly reduced or absent. These observations suggest that IgA nephropathy patients have a defect in raising a mucosal IgA response against novel microbial antigens and that they will suffer from recurrent mucosal infections until they have developed a large enough repertoire of memory B-cells to protect their mucosal surfaces. As a consequence of the recurrent stimulation of the IgA immune system, high levels of plasma IgA are found. The mechanism of IgA deposit formation in the mesangium is unknown. The ensuing inflammatory reaction in the glomeruli may vary from mild to severe, but usually the disease has an indolent course. The progression of IgA nephropathy to renal failure is clinically the most important complication. Recent observations on the role of cytokines in the pathogenesis of interstitial infiltration, interstitial fibrosis and tubular atrophy have created the opportunity to study and manipulate the process of renal scarring and the progression to renal failure.

    Antibacterial Activity of Carvacrol, Citral, and Geraniol against Salmonella typhimurium in Culture Medium and on Fish Cubes (1995)

    Notes: Carvacrol, citral and geraniol showed potent antibacterial activity against Salmonella typhimurium and its rifampicin-resistant (RifR) strain as determined in txyptic soy broth and by zone of inhibition on agar-based medium. Carvacrol had the most potent bactericidal activity, with minimum inhibitory and bactericidal concentrations (MIC and MBC) of 250 μg/mL for both tester strains. When tested at 0.5, 1.5 and 3.0% in 1% Tween 20 for bactericidal activity against RifR-S. typhimurium inoculated on fish cubes, carvacrol at 3.0% completely killed the inoculated bacteria, while geraniol killed most of the bacteria, and citral killed the least. Carvacrol and geranial showed potent antibacterial activity at 1.5%. Bactericidal activity became more evident as storage of fish cubes at 4°C lengthened. The comparable inhibition of these strains of Salmonella and species of Gram-negative bacteria by carvacrol and geraniol support their application as potential antibacterial agents in food systems.
