Abstract
The number of peripheral blood mononuclear cells (PBMC) producing IgA, IgG and IgM spontaneously, after in vitro polyclonal stimulation with pokeweek mitogen (PWM) and in response to autologous mixed lymphocyte reaction (AMLR), were determined by a protein A hemolytic plaque assay in 23 patients with IgA nephropathy confirmed by renal biopsies and in 24 normal controls. The geometric mean of circulating IgA-producing cells in Berger's disease (689 +/- 1.73 cells/10(6) PBMC) was increased when compared with the normal controls (332 X divided by 1.52 cells/10(6) PBMC; p less than 0.001). To a lesser degree, there was also an increase in the number of IgG-secreting cells (98 +/- 3.97 cells/10(6) PBMC vs. 38 +/- 2.90 cells/10(6) PBMC; p less than 0.05). After PWM stimulation, although the number of IgA-producing cells was increased in patients with IgA nephropathy, no significant differences were observed between the 2 groups. In response to AMLR, the number of IgA-secreting cells was significantly higher in the cases with Berger's disease (1,979 +/- 1.76 cells/10(6) non-T cells vs. 783 +/- 1.95 cells/10(6) non-T cells; p less than 0.001). Although it did not reach statistical significance, the patient group had also an increase in the number of IgG-producing cells (884 +/- 2.64 cells/10(6) non-T cells vs. 317 +/- 5.05 cells/10(6) non-T cells). These data support the existence of some abnormalities in the mechanisms regulating the synthesis of IgA in Berger's disease which might contribute to its pathogenesis.

Abstract
Intravenous infusion of free fatty acid (FFA) produces pulmonary edema and an increase in the alveolar surfactant content of the rabbit. In order to identify a likely mediator of this lung response to FFA, we used inhibitors of cyclo-oxygenase (indomethacin, 15 mg X kg-1 i.v., or meclofenamate, 5 mg X kg-1 i.v.) and thromboxane synthetase inhibitors (imidazole, 50 mg X kg-1 i.v. or dazoxiben, 2 mg X kg-1 i.v.) which were administered before FFA, 20 mg X kg-1 X min-1 i.v., in four different experimental series (n = 54). Lung surfactant was measured in bronchial-alveolar lavage fluid by determining disaturated phosphatidylcholine (DSPC). Both kinds of inhibitors blocked the increase in FFA-induced DSPC. They increased the survival rate but they only slightly changed the post-FFA morphofunctional pulmonary alterations. We conclude that the increase in alveolar surfactant induced by FFA is likely mediated by thromboxane. This mediator would seem to play a minor role in the FFA-induced pulmonary edema observed.

Abstract
Peripheral blood lymphocytes (PBL) producing IgA, IgM, and IgG, both spontaneously and after pokeweed mitogen stimulation in cell culture, were determined by a protein A hemolytic plaque assay in 20 children with active Henoch-Schönlein purpura (HSP), 42 with inactive disease, 22 normal controls of the same ages, and 18 children with upper respiratory tract infections (URTI). The geometric mean of circulating IgA-producing cells in active HSP (1,016 X divided by 1.55 cells/10(6) PBL) was increased when compared with the group with inactive disease (P less than 0.001), normal controls (P less than 0.001), and children with URTI (542 X divided by 2.03 cells/10(6) PBL, P less than 0.05). The number of circulating IgM-producing cells was slightly increased in active HSP (260 X divided by 2.65 cells/10(6) PBL) and URTI (256 X divided by 3.16 cells/10(6) PBL). Both values were higher than those found in the group with inactive disease (113 X divided by 2.26 cells/10(6) PBL, P less than 0.01). There were no significant differences among the 4 groups in the number of circulating IgG-producing cells. The number of cells producing each type of immunoglobulin after in vitro stimulation with pokeweed mitogen was similar in patients with active HSP, normal controls, and the group with inactive disease. These data demonstrate a selective increase in the number of circulating IgA-producing cells only during disease activity, and add further support to a possible pathogenic role of this immunoglobulin in HSP.

Abstract
Acute poststreptococcal glomerulonephritis is one of the best defined renal diseases and it is the commonest form of acute glomerulonephritis in children. Antigen-antibody complexes formed in the circulation or "in situ" seem to play an important role in the pathogenesis and even though antiglobulins have recently been incriminated, there is still controversy over the nature of the antigen/s involved. Usually the clinical picture is very characteristic, but in those cases of atypical presentation mainly in those without urinary abnormalities, the diagnosis could be resolved by demonstration of well defined histological lesions. Although it is generally agreed upon, on the basis of clinical observations, that recovery from acute glomerulonephritis generally occurs in children, confusion still exists concerning the precise frequency with which chronicity may happen in this disease. There is no specific treatment for the immunological processes but symptomatic therapy has considerably reduced early mortality.

Abstract
The initial enzymic step in mercapturic acid formation is catalyzed by glutathione S-transferase. Several species of this enzyme, designated as transferases alpha, beta, gamma, delta and epsilon on the basis of increasing isoelectric points, were isolated from human liver. Evidence is presented that each of the purified species is homogeneous with respect to sodium dodecylsulfate-gel electrophoresis. Transferases alpha, beta and epsilon each appear as a single band on gel electrofocusing; transferases gamma and delta are present as two and three bands, respectively, with each band catalytically active. Amino acid analysis indicated the five transferases to be either very closely related or identical in this respect. All enzyme species have a molecular weight of about 48500 and consist of two apparently identical subunits. The spectrum of substrates is the same for each although the enzymes differ slightly in specific activity. As is the case for the rat liver enzymes, each of the human transferases binds bilirubin although this compound is not a substrate.
