Interfacial rheology of blood proteins adsorbed to the aqueous-buffer/air interface

Concentration-dependent, interfacial-shear rheology and interfacial tension of albumin, IgG, fibrinogen, and IgM adsorbed to the aqueous-buffer/air surface is interpreted in terms of a single viscoelastic layer for albumin but multi-layers for the larger proteins. Two-dimensional (2D) storage and loss moduli G(') and G('), respectively, rise and fall as a function of bulk-solution concentration, signaling formation of a network of interacting protein molecules at the surface with viscoelastic properties. Over the same concentration range, interfacial spreading pressure Pi(LV) identical with gamma(lv)(o)-gamma(lv) rises to a sustained maximum Pi(LV)(max). Mixing as little as 25 w/v% albumin into IgG at fixed total protein concentration substantially reduces peak G('), strongly suggesting that albumin acts as rheological modifier by intercalating with adsorbed IgG molecules. By contrast to purified-protein solutions, serially diluted human blood serum shows no resolvable concentration-dependent G(')and G(').

Relationship between ovarian stimulation regimen and interleukin level in pre-ovulatory follicular fluid and their effect on ICSI outcome

PROBLEM: The aims of this study were (i) to identify the presence and concentration of interleukin-6 (IL-6), IL-8 and granulocyte-macrophage colony-stimulating factor (GM-CSF) in pre-ovulatory follicular fluid (FF) in patients undergoing controlled ovarian hyperstimulation regimen for intracytoplasmic sperm injection (ICSI) with recombinant human follicle stimulating hormone (rFSH) (G.1), hMG (G.2) or rFSH/ hMG (G.3) treatment and (ii) to determine whether controlled ovarian hyperstimulation stimulation regimen could affect the concentration of these investigated interleukins and as a consequences the ICSI outcome. (iii) Moreover, it was intended to clarify the association between these investigated parameters and the peripheral blood level of estradiol 17-beta, progesterone, leuteinizing hormone (LH) at the day of oocyte retrieval and (iv) finally to find out whether these interleukin concentrations in FF could be considered as an additional parameter for predicting fertilization and pregnancy outcome in ICSI patients. MATERIAL AND METHODS: Interleukin-6, IL-8 and GM-CSF concentrations were determined in the FF of 85 patients. The levels of these interleukins were measured by the enzyme-linked immunosorbent assay (ELISA) technique, using commercially available kits. RESULTS: Interleukin-6 (6.5 +/- 4.6 pg/mL), IL-8 (222.9 +/- 163.4 pg/mL) and GM-CSF (1.6 +/- 2.7 pg/mL) were present in pre-ovulatory FF in ICSI patients. No significant difference in the mean concentration of IL-6, IL-8 and GM-CSF was found between the groups. Moreover, there was no correlation between these interleukin levels in FF and steroid hormone concentration in the peripheral blood. CONCLUSIONS: Interleukin-6, IL-8 and GM-CSF were found in FF of patients undergoing ovarian hyperstimulation for ICSI treatment. The stimulation protocols showed no influence on these interleukin levels in FF. Moreover, no correlation was found between these investigated interleukins and steroid hormone concentrations in peripheral blood or ICSI outcome. Therefore, the determination of interleukin level in FF of patients undergoing ovarian hyperstimulation for ICSI therapy could not be recommended as a prognostic factor for ICSI outcome.     

Effects of oral base therapy on serum ionized calcium, phosphorus and parathyroid hormone in chronic hemodialysis patients

The purpose of this study was to evaluate the effects of oral base therapy on selected chemical parameters in chronic hemodialysis patients. Oral base supplements were administered to 20 acidotic chronic hemodialysis patients for one month. Serum bicarbonate levels rose from 18.6 +/- 2.9 to 22.5 +/- 4.0 mEq/L (p less than 0.0005) and pH rose from 7.35 +/- 0.03 to 7.39 +/- 0.04 (p less than 0.0005). Serum ionized calcium levels fell from 5.03 +/- 0.37 to 4.83 +/- 0.34 mg/dL (1.25 +/- 0.09 to 1.21 +/- 0.08 mmol/L) (p less than 0.01), while intact parathyroid hormone (PTH) levels rose from 547 +/- 697 to 619 +/- 776 pg/mL (p less than 0.05). Base therapy did not result in significant changes in serum levels of total calcium, phosphorus, alkaline phosphatase, urea nitrogen, creatinine, total protein, albumin or potassium. If empiric therapy with exogenous base is given to dialysis patients, ionized calcium levels should be closely monitored since changes in calcium supplement or vitamin D therapy may be required to maintain ionized calcium and parathyroid hormone values at the pre-treatment levels.

Antisense co-suppression of G(alpha)(q) and G(alpha)(11) demonstrates that both isoforms mediate M(3)-receptor-activated Ca(2+) signalling in intact epithelial cells

We used replication-deficient adenoviruses overexpressing antisense against G(q) class alpha-subunits to determine the roles of G(q) and G(11) in mediating M(3)-receptor-coupled Ca(2+) mobilization in intact HT29 human colonic carcinoma epithelial cells. Western blot analysis and confocal microscopy showed that the viruses expressing antisense directed against the alpha-subunits of G(q) or G(11) produced isoform-specific reductions in the levels of these alpha-subunits. Fura-2 was used to measure changes in the Ca(2+) response following activation of the M(3) receptors by carbachol. The G(alpha)(q) antisense virus suppressed the peak Ca(2+) response by 70%, whereas the G(alpha)(11) antisense virus reduced it by 34%. We then used co-infection with both viruses to determine the effect of concomitant suppression of both G(alpha)(q) and G(alpha)(11). Overexpression of antisense to both alpha-subunits reduced by approximately 50% the levels of both G(alpha)(q) and G(alpha)(11). It also almost completely inhibited the Ca(2+) response to carbachol. These data show that both G(q) and G(11) are involved in mediating the action of the M(3) receptor on cytosolic Ca(2+) in HT29 cells. Furthermore, they suggest that the coupling of the M(3) receptor to these G proteins is specific, in that G(alpha)(q) cannot substitute for G(alpha)(11), and vice versa.     

Study of monoclonal gammopathy in Kagawa Prefectural Central Hospital

We investigated 361 patients with monoclonal gammopathy in whom immunoelectrophoresis was performed (1,037 tests) between 1986 and 2002 at Kagawa Prefectural Central Hospital. In this study, we identified 222 patients with monoclonal gammopathy of undetermined significance (MGUS). Malignant transformation of MGUS to multiple myeloma occurred in 15 patients (6.8%). No significant differences were observed in the means of total protein (TP), albumin (Alb), albumin/globulin ratio (A/G ratio), IgG, IgA, or IgM level in the initial examination between the patients who remained as MGUS and patients with malignant transformation of MGUS. However, the rate of progression to malignancy was high when the levels of normal immunoglobulins other than M protein were below the normal range. Since the number of MGUS cases detected and the number of protein fractionation performed were proportionate, and MGUS was found by protein fractionation in routine tests, protein fractionation is essential for detection of MGUS, and it is necessary to add serum protein fractionation to routine initial examination. In addition, long-term follow-up of patients with monoclonal gammopathy and preparation of a database of patient information are useful for monitoring the outcome.     

Role of interleukin-8 (IL-8) and an inhibitory effect of erythromycin on IL-8 release in the airways of patients with chronic airway diseases.

To evaluate of the role of interleukin-8 (IL-8), a chemotactic cytokine, in the continuous neutrophil accumulation in the airways of patients with chronic airway disease (CAD) and persistent Pseudomonas aeruginosa infection, we investigated the cell population, IL-8 levels, IL-1 beta levels, tumor necrosis factor (TNF) activities, and neutrophil elastase (NE) activities of bronchoalveolar lavage (BAL) fluids in 17 CAD patients (with P. aeruginosa infections [CAD+PA], n = 9; without any bacterial infections [CAD-PA], n = 8) and 8 normal volunteers. We found significant elevations of neutrophil numbers, IL-8/albumin ratios, and NE/albumin ratios in BAL fluids from CAD patients, in the following rank order: CAD+PA > CAD-PA > normal volunteers. IL-1 beta/albumin ratios were elevated only in CAD+PA, while no TNF bioactivity was detected in BAL fluids. The neutrophil numbers correlated significantly with the IL-8/albumin ratios and NE/albumin ratios in the BAL fluids of CAD patients. When anti-human IL-8 immunoglobulin G was used for neutralizing neutrophil chemotactic factor (NCF) activities in BAL fluids, the mean reduction rate of NCF activities in CAD+PA patients was significantly higher than that in CAD-PA patients. We also evaluated the effects of low-dose, long-term erythromycin therapy in BAL fluids from three CAD+PA and two CAD-PA patients. Treatment with erythromycin caused significant reductions of neutrophil numbers, IL-8/albumin ratios, and NE/albumin ratios in BAL fluids from these patients. To elucidate the mechanism of erythromycin therapy, we also examined whether erythromycin suppressed IL-8 production by human alveolar macrophages and neutrophils in vitro. We demonstrated a moderate inhibitory effect of erythromycin on IL-8 production in Pseudomonas-stimulated neutrophils but not in alveolar macrophages. Our data support the view that persistent P. aeruginosa infection enhances IL-8 production and IL-8-derived NCF activity, causing neutrophil accumulation in the airways and the progressive lung injuries observed in patients with CAD. The clinical efficacy of erythromycin therapy for CAD patients might be partly mediated through a reduced IL-8 production, diminishing neutrophil accumulation and NE release in the airways.
