Gamma interferon stimulates rat alveolar macrophages to kill Pneumocystis carinii by L-arginine- and tumor necrosis factor-dependent mechanisms. (1/4121)

Pneumocystis carinii pneumonia remains a serious complication for immunocompromised patients. In the present study, P. carinii organisms interacted with gamma interferon (IFN-gamma)-stimulated alveolar macrophages (AMs) to activate the L-arginine-dependent cytocidal pathway involving reactive nitrogen intermediates (RNI) that were assayed as nitrite (NO2-). Unstimulated cultures of AMs produced negligible quantities of RNI. Addition of P. carinii organisms to IFN-gamma-primed AMs resulted in greatly enhanced production of RNI. NO2- levels increased from 0.8 +/- 0.4 to 11.1 +/- 3.8 microM as early as 6 h after P. carinii organisms were incubated with IFN-gamma-stimulated AMs and to 35.1 +/- 8.9 microM after a 24-h incubation, a near-maximum level. High levels of NO2- were produced by AMs primed with as little as 10 U of IFN-gamma per ml in the presence of P. carinii, and a 20-fold increase in IFN-gamma concentration resulted in only a further 65% increase in NO2- production. RNI-dependent killing of P. carinii was demonstrated by both a 51Cr release assay and a [35S]methionine pulse immunoprecipitation assay. Addition of either monoclonal tumor necrosis factor alpha (TNF-alpha) neutralizing antibody or 200 microM NG-monomethyl-L-arginine (L-NGMMA), a competitive inhibitor of the L-arginine-dependent pathway, significantly decreased NO2- production and reduced P. carinii killing. TNF-alpha alone had no effect on P. carinii viability. These results suggest that (i) the specific interaction of P. carinii organisms with IFN-gamma-primed AMs triggers the production of RNI, (ii) RNI are toxic to P. carinii, and (iii) TNF-alpha likely plays a central role in mediating P. carinii killing by IFN-gamma-stimulated AMs.  (+info)

Proteinuria induces tubular cell turnover: A potential mechanism for tubular atrophy. (2/4121)

BACKGROUND: Proteinuria and tubular atrophy have both been closely linked with progressive renal failure. We hypothesized that apoptosis may be induced by tubular cell exposure to heavy proteinuria, potentially leading to tubular atrophy. Apoptosis was studied in a rat model of "pure" proteinuria, which does not induce renal impairment, namely protein-overload proteinuria. METHODS: Adult female Lewis rats underwent intraperitoneal injection of 2 g of bovine serum albumin (BSA, N = 16) or sham saline injections (controls, N = 8) daily for seven days. Apoptosis was assessed at day 7 in tissue sections using in situ end labeling (ISEL) and electron microscopy. ISEL-positive nuclei (apoptotic particles) were counted in blinded fashion using image analysis with NIH Image. Cell proliferation was assessed by detection of mRNA for histone by in situ hybridization, followed by counting of positive cells using NIH Image. RESULTS: Animals injected with saline showed very low levels of apoptosis on image analysis. BSA-injected rats had heavy proteinuria and showed both cortical and medullary apoptosis on ISEL. This was predominantly seen in the tubules and, to a lesser extent, in the interstitial compartment. Overall, the animals injected with BSA showed a significant 30-fold increase in the number of cortical apoptotic particles. Electron microscopy of tubular cells in a BSA-injected animal showed a progression of ultrastructural changes consistent with tubular cell apoptosis. The BSA-injected animals also displayed a significant increase in proximal tubular cell proliferation. This increased proliferation was less marked than the degree of apoptosis. CONCLUSION: Protein-overload proteinuria in rats induces tubular cell apoptosis. This effect is only partially balanced by proliferation and potentially provides a direct mechanism whereby heavy proteinuria can induce tubular atrophy and progressive renal failure.  (+info)

Endothelin up-regulation and localization following renal ischemia and reperfusion. (3/4121)

BACKGROUND: Endothelin (ET), a potent vasoconstrictor, is known to play a role in ischemic acute renal failure. Although preproET-1 (ppET-1) mRNA is known to be up-regulated following ischemia/reperfusion injury, it has not been determined which component of the injury (ischemia or reperfusion) leads to initial gene up-regulation. Likewise, although ET-1 peptide expression has been localized in the normal kidney, its expression pattern in the ischemic kidney has not been determined. Therefore, the purpose of this study was twofold: (a) to determine whether ischemia alone or ischemia plus reperfusion is required for the up-regulation of ppET-1 mRNA to occur, and (b) to localize ET-1 peptide expression following ischemia in the rat kidney to clarify better the role of ET in the pathophysiology of ischemia-induced acute renal failure. METHODS: Male Lewis rats underwent clamping of the right renal vascular pedicle for either 30 minutes of ischemia (group 1), 60 minutes of ischemia (group 2), 30 minutes of ischemia followed by 30 minutes of reperfusion (group 3), or 60 minutes of ischemia followed by three hours of reperfusion (group 4). The contralateral kidney acted as a control. ppET-1 mRNA up-regulation and ET-1 peptide expression were examined using the reverse transcription-polymerase chain reaction and immunohistochemistry, respectively. RESULTS: Reverse transcription-polymerase chain reaction yielded a control (nonischemic) value of 0.6 +/- 0.2 densitometric units (DU) of ppET-1 mRNA in the kidney. Group 1 levels (30 min of ischemia alone) were 1.8 +/- 0.4 DU, a threefold increase (P < 0.05). Group 2 levels (60 min of ischemia alone) increased almost six times above baseline, 3.5 +/- 0.2 DU (P < 0.01), whereas both group 3 and group 4 (ischemia plus reperfusion) did not experience any further significant increases in mRNA levels (1.9 +/- 0.4 DU and 2.8 +/- 0.6 DU, respectively) beyond levels in group 1 or 2 animals subjected to similar ischemic periods. ET-1 peptide expression in the ischemic kidneys was significantly increased over controls and was clearly localized to the endothelium of the peritubular capillary network of the kidney. CONCLUSIONS: Initial ET-1 gene up-regulation in the kidney occurs secondary to ischemia, but reperfusion most likely contributes to sustaining this up-regulation. The marked increase of ET-1 in the peritubular capillary network suggests that ET-induced vasoconstriction may have a pathophysiological role in ischemic acute tubular necrosis.  (+info)

Characterization of CD4+ CD8alphaalpha+ and CD4-CD8alphaalpha+ intestinal intraepithelial lymphocytes in rats. (4/4121)

Intestinal intraepithelial lymphocytes (i-IEL) of aged rats comprise CD4+CD8alphaalpha+ and CD4-CD8alphaalpha+ T cells expressing TCR alphabeta. In the present study, we compared characteristics between CD4+CD8alphaalpha+ and CD4-CD8alphaalpha+ i-IEL, which were purified by a cell sorter from the i-IEL of 6-month-old Lewis rats. Most of the CD4+CD8alphaalpha+ i-IEL were of the CD44(hlgh) phenotype, while CD4-CD8alphabeta+ i-IEL were CD44(low). Vbeta usage in the CD4-CD8alphaalpha+ i-IEL was much diversified, while CD4+CD8alphaalpha+ i-IEL showed a skewed Vbeta repertoire. The CD4+CD8alphaalpha+ i-IEL but not the CD4-CD8alphaalpha+ i-IEL proliferated in response to syngeneic spleen cells, which was partially inhibited by addition of anti-MHC class I mAb. The CD4+CD8alphaalpha+ i-IEL produced IFN-gamma and IL-2 but no IL-4 or transforming growth factor (TGF)-beta in response to syngeneic spleen cells, while CD4-CD8alphaalpha+ i-IEL produced abundant levels of TGF-beta but no IL-2, IFN-gamma or IL-4. CD4+CD8alphaalpha+ i-IEL proliferated in response to exogenous IL-2 but not to IL-15, while CD4-CD8alphaalpha+ i-IEL could respond to IL-15 as well as IL-2. These results suggest that a significant fraction of CD4+CD8alphaalpha+ i-IEL belongs to Th1-type T cells capable of responding to self-MHC class I, while CD4-CD8alphaalpha+ i-IEL are a unique population with a diversified Vbeta repertoire that respond to IL-15 in rats.  (+info)

Hormonal prevention of breast cancer: mimicking the protective effect of pregnancy. (5/4121)

Full term pregnancy early in life is the most effective natural protection against breast cancer in women. Rats treated with chemical carcinogen are similarly protected by a previous pregnancy from mammary carcinogenesis. Proliferation and differentiation of the mammary gland does not explain this phenomenon, as shown by the relative ineffectiveness of perphenazine, a potent mitogenic and differentiating agent. Here, we show that short term treatment of nulliparous rats with pregnancy levels of estradiol 17beta and progesterone has high efficacy in protecting them from chemical carcinogen induced mammary cancers. Because the mammary gland is exposed to the highest physiological concentrations of estradiol and progesterone during full term pregnancy, it is these elevated levels of hormones that likely induce protection from mammary cancer. Thus, it appears possible to mimic the protective effects of pregnancy against breast cancer in nulliparous rats by short term specific hormonal intervention.  (+info)

Decreased hexosamine biosynthesis in GH-deficient dwarf rat muscle. reversal with GH, but not IGF-I, therapy. (7/4121)

Enhanced glucose flux via the hexosamine biosynthesis pathway (HNSP) has been implicated in insulin resistance. We measured L-glutamine:D-fructose-6-phosphate amidotransferase activity (GFAT, a rate-limiting enzyme) and concentrations of UDP-N-acetyl hexosamines (UDP-HexNAc, major products of HNSP) in muscle and liver of growth hormone (GH)-deficient male dwarf (dw) rats. All parameters measured, except body weight, were similar in 5-wk-old control and dw rats. Muscle GFAT activity declined progressively with age in controls and dw rats but was consistently 30-60% lower in 8- to 14-wk-old dw rats vs. age-matched controls; UDP-HexNAc concentrations in muscle were concomitantly 30% lower in dw rats vs. controls (P < 0.01). Concentrations of UDP-hexoses, GDP-mannose, and UDP in muscle were similar in control and dw rats. Muscle HNSP activity was similarly diminished in fed and fasted dw rats. In liver, only a small difference in GFAT activity was evident between controls and dw rats, and no differences in UDP-HexNAc concentrations were observed. Treatment with recombinant human GH (rhGH) for 5 days restored UDP-HexNAc to control levels in dw muscles (P < 0.01) and partially restored GFAT activity. Insulin-like growth factor I treatment was ineffective. We conclude that GH participates in HNSP regulation in muscle.  (+info)

Decreased lactic acidosis and anemia after transfusion of o-raffinose cross-linked and polymerized hemoglobin in severe murine malaria. (8/4121)

Severe anemia is a major cause of death in falciparum malaria. Blood transfusion increases survival in humans and in animal models of this disease. Because of logistic constraints and viral contamination of the blood supply, transfusions are frequently not practical in endemic regions. Modified hemoglobin is an effective O2 carrier in hemorrhagic shock. It is free of infectious contamination, may not require refrigeration, and because of its nitric oxide scavenging and small size, may have pharmacologic benefits in malaria. The effects of transfusions of modified hemoglobin in rats with high-grade parasitemia were evaluated. Modified hemoglobin decreased lactic acidosis and corrected anemia as well as transfusions with red blood cells; these findings may correlate with improved survival and suggest a possible proerythropoietic effect. Further study of this novel therapy is warranted.  (+info)

Methods Inflammatory arthritis was induced by twice injections of bovine collagen II (day 0, day 7) in female Lewis rats. Rats were monitored for joint swelling, pain, redness and mobility (score 0 to 3). The TNFa binding protein etanercept (Enbrel®, Pfizer) was chemically conjugated with an ICG derivative suited for labeling of proteins. The etanercept-6S-ICG (Eta-6S-ICG) conjugate was photophysically characterized and tested for binding affinity The fluorescence camera system Xiralite (mivenion GmbH, Germany) [1] was modified to enable imaging of rats. On day 14 after first injection of collagen, Eta-6S-ICG (n=6), IgG-6S-ICG (n=3), or the inflammation-targeted macromolecule polyglycerolsulfate-6S-ICG (dPGS-6S-ICG, n=5) [2] were s.c. or i.v. injected in a dose of 10 nMol/kg b.w. Fluorescence measurement was performed before and 1 h, 3 h, 24 h and 48 h after injection. Fluorescence intensity (FI) was measured in ROI over the tibio-tarsal and interphalangeal articulations and compared with ...
Purpose: Frequent intravitreal injections of monoclonal anti-VEGF agents Lucentis and Avastin were shown to reverse the effects of wet AMD. These injections, however, predispose patients to endophthalmitis and stroke, among other ocular and systemic adverse effects. Such complications, as well as patient discomfort, would be potentially reduced or even eliminated by the delivery of these drugs in mist or drop form. The purpose of this study was to obtain pilot data regarding the feasibility of delivering potentially therapeutic large, hydrophilic antibodies to the posterior pole by eye drop application.. Methods: Female Lewis rats received a single 25 mg/10 µL topical dose of whole mouse monoclonal IgG1 antibody in PBS without a permeation enhancer into one eye; control rats were left untreated. The concentration of IgG1 was determined in retinal and optic nerve homogenates 10 to 20 minutes later using an ELISA; tissues were homogenized in lysis buffer containing protease inhibitors. Data are ...
Demyelination. Adult female Lewis rats were anesthetized, and the sciatic nerve in one leg, just proximal to the sciatic notch, was exposed. The three branches of the sciatic nerve were injected with 1-2 μl of 1% lysolecithin in sterile Lockes solution by using a glass micropipette broken to a tip diameter of ∼20 μm. Then the incision was closed, and the animal was allowed to recover for 6-69 d. Some animals were injected with both lysolecithin and mitomycin-C (400 mg/ml; Sigma, St. Louis, MO) to block Schwann cell proliferation subsequent to demyelination. The Lockes solution contained (in mm): NaCl 154, KCl 5.6, CaCl2 2, and HEPES 10, pH 7.4.. Axon preparation. On the appropriate day postinjection, the animal was killed; the sciatic nerve was dissected immediately, desheathed, and dissociated into single fibers by treatment with collagenase (3.6 mg/ml; Sigma) for 1 hr at room temperature (RT). Fibers were teased apart gently and spread on coverslips that had been coated in a few spots ...
In order to determine the origin of brain phagocytes brain slices and optic nerve segments from adult Lewis rats were transplanted into the peritoneal cavity of syngenic recipients. The specimens were contained in Millipore diffusion chambers fitted with membranes of either 0.22 or 5.0 microns pore size. The either blocked or allowed the access of non-resident cells. Each recipient rat received both a 0.22 and 5.0 microns pore chamber. Later (3-16 days), the specimens were recovered and analyzed by monoclonal antibody techniques and electron-microscopy. Endothelia, GFAP+ astrocytes, ED1-/ED2+/RCA-1+/OX-6-perivascular cells and ED1-/ED2-/RCA-1+/lysozyme--microglia were found to have survived the procedure. Cells of the macrophage phenotype (ED1+/ED2+/RCA-1+/lysozyme+/vimentin+ with phagocytic vacuoles), however, were only found in large numbers in specimens kept within 5.0 microns pore size chambers, giving access to non-resident cells, and were exceedingly rare in specimens from 0.22-micron pore
Animals and tissues. Tissues of embryonic and postnatal Lewis rats were used in this study. The day of vaginal plug detection was considered embryonic day 1 (E1). Pregnant females were decapitated, and the embryos (E14, E16, and E19) were rapidly removed, embedded in Tissue Tek (OCT compound; Zoeterwoude), and frozen in isopentane at −40°C for subsequent in situ hybridization and immunohistochemistry. Brain, spinal cord, and eyes of postnatal animals from postnatal day 0 (P0), P1, P3, P5, P9, P14, and adult animals were removed and processed as indicated above. Each developmental time point was analyzed in at least three different animals. In addition, tissues from adult decapitated animals were collected for Western and Northern blotting. For confocal microscopy, adult Lewis rats were killed with pentobarbital (500 mg/kg) and perfused transcardially with Ringers solution followed by 4% paraformaldehyde in 0.15 m phosphate buffer with 5% sucrose. The spinal cords were removed and post-fixed ...

This study was initiated to explore the effect of recombinant rat Crry linked to the Fc portion of rat IgG2a (Crry-Ig) on the induction of experimental autoimmune anterior uveitis (EAAU) and on established disease. EAAU was induced in Lewis rats by immunization with bovine melanin-associated antigen (MAA). MAA sensitized animals received Crry-Ig, rat IgG2a (isotype control) or PBS separately before the onset of EAAU or after the onset of clinical disease. Administration of Crry-Ig suppressed the induction of EAAU while all animals injected with IgG2a or PBS developed the normal course of EAAU. Treatment with Crry-Ig resulted in the suppression of ocular complement activation as well as the functional activity of complement in the peripheral blood. At the peak of EAAU, levels of IFN-γ, IP-10, ICAM-1 and LECAM-1 were significantly reduced within the eyes of Crry-Ig treated Lewis rats. Importantly, administration of Crry-Ig even after the onset of EAAU resulted in a sharp decline in the disease ...
There is compelling experimental evidence to show that transplantation of skeletal myoblasts (SMBs) improves the function of failing hearts via paracrine effects. However, clinical application of this strategy has been curtailed due to arrhythmia occurrence and inconsistent outcomes observed in previous clinical trials of intramyocardial (IM) injection of SMBs. Severe inflammation and resultant global reduction of connexin43 have been reported to be causes of the arrhythmogenicity. Recent developments in bioengineering technology enabled production of cell sheets using temperature-responsive culture dishes, which allows retrieval of cells without enzymatic dissociation-related damages. We hypothesized that epicardial attachment of cell sheets would enhance retention, survival, and maintenance of functions of donor SMBs in the heart, with less myocardial injury, and therefore overcome the drawbacks of IM injection.. Methods & Results: After left coronary artery ligation in female Lewis rats, ...
TY - JOUR. T1 - Phenotypes of T cells infiltrating the eyes in autoimmune anterior uveitis associated with EAE. AU - Zhang, Xingqi. AU - Jiang, Shuguang. AU - Manczak, Maria. AU - Sugden, Brad. AU - Adamus, Grazyna. PY - 2002. Y1 - 2002. N2 - PURPOSE. Lewis rats immunized with myelin basic protein (MBP) develop experimental autoimmune encephalomyelitis (EAE) and associated anterior uveitis (AU), which recurs. The goal was to analyze cellular activation markers and adhesion molecules of T cells that infiltrate the eyes and spinal cord during acute and recurrent AU in actively and passively induced diseases simultaneously in the same animals. METHODS. EAE-AU was induced in Lewis rats by immunization with MBP in CFA, or by adoptive transfer of MBP-specific T-cell lines, and the signs of clinical EAE and AU was scored. Cells isolated from the iris-ciliary body were tested by flow cytometry for expression of CD4, CD8, CD45RC, T-cell receptor (TCR) Vβ8.2, α4 integrin, L-selectin, CD44, and CD134. ...
Most antirheumatic therapies are given systemically, which may result in complications because of the high dosage needed to achieve therapeutic levels in the joints. Gene therapy might provide a more efficient system to deliver therapeutic compounds at the site of inflammation. The artificial chromosome expression system (ACes) is a unique, nonintegrating, nonviral gene-expression system, which functions like a natural chromosome. This technology offers advantages over current expression systems because it allows stable expression of genes producing single or multiple proteins over long periods. We are developing ex vivo gene therapy using artificial chromosomes containing reporter genes (LacZ or RFP) for local delivery of genes in rats with adjuvant arthritis. The aim of this study was to evaluate the transfection efficiency in cell lines or primary cells, including rat skin fibroblasts (RSFs) and fibroblast-like synoviocytes (FLSs). Furthermore, we investigated the feasibility of local ...
The present study was performed to investigate the role of IL-1R/TLR signaling in joint inflammation induced by bacterial cell wall fragments (SCW) from S. pyogenes. To this end, we induced SCW arthritis in mice that are deficient for MyD88, the pivotal adaptor molecule in the IL-1R/TLR signaling cascade. In addition, we analyzed whether joint inflammation, elicited by local injection of SCW fragments, was mediated by TLR-2 or TLR-4. Therefore, mice deficient for either TLR-2 or TLR-4 were included in this study.. TLRs are present on several cell types, including fibroblasts, macrophages, and dendritic cells (1, 2, 3, 4, 5, 6). Recently, it was shown that synovial fibroblasts express mainly TLR-2 since fibroblasts from RA patients could be activated by TLR-2 (bacterial peptidoglycans) and not by TLR-9 (CpG motifs) agonists to produce proinflammatory cytokines and matrix metalloproteinases (41). Expression of TLR-2 and TLR-4 but not TLR-9 was found in synovial biopsies of RA patients with active ...
Differences in spontaneous allograft acceptance after liver transplantation among inbred rat strains might be explained by variation in the local production of TNF-α as a potent mediator of the inflammatory response. In this study, we hypothesize that nucleotide differences in the rat Tnf gene influence TNF-α protein expression. As such, polymorphisms in the Tnf gene may also provide a possible explanation for differences in survival of allogeneic liver grafts among inbred rat strains. We therefore investigated the capacity of mononuclear cells to produce TNF-α in response to a mitogenic stimulus and the Tnf locus was sequenced in six different inbred rat strains. Among the six strains (AUG, BN, DA, LEW, PVG and WF), 44 nucleotide differences including 36 single nucleotide polymorphisms (SNPs), five simple sequence length polymorphisms, two deletions and one insertion, were found in the Tnf gene. Although, the inbred rat strains differed significantly in mean levels of maximum TNF-α ...
Animals. Lewis rats were obtained from Charles River and were maintained in isolation cages in the Department of Laboratory and Animal Resources at the University of Pittsburgh. Animals were housed in temperature- and light/dark cycle-controlled rooms.. Induction of liver cirrhosis. Liver cirrhosis was induced as described previously by using phenobarbital and CCl4 (both Sigma-Aldrich) when inbred male Lewis rats, weighing 100-130 g, were 4 weeks old (16). Rats were given phenobarbital (0.5 g/l) added to the drinking water. Starting 2 weeks later, CCl4 (diluted 1:9 in olive oil) was administered by gavage twice a week. Following an initial dose of 0.2 ml/kg, each subsequent dose was adjusted weekly on the basis of changes in body weight. If body weight increased or remained unchanged, CCl4 was continued at 0.2 ml/kg twice weekly. When body weight decreased by 1-5 g, the dose of CCl4 was reduced to 0.15 ml/kg, and if body weight decreased by 6-10 g, the CCl4 was reduced to 0.1 ml/kg. In rats that ...
Abs to the α-chain of the IL-2 receptor (anti-CD25) are used clinically to achieve immunosuppression. Here we investigated the effects of DNA vaccination with the whole CD25 gene on the induction of rat adjuvant arthritis. The DNA vaccine protected the rats and led to a shift in the cytokine profile of T cells responding to disease target antigens from Th1 to Th2. The mechanism of protection was found to involve the induction of an antiergotypic response, rather than the induction of anti-CD25 Abs. Antiergotypic T cells respond to activation molecules, ergotopes, expressed on syngeneic activated, but not resting, T cells. CD25-derived peptides function as ergotopes that can be recognized by the antiergotypic T cells. Antiergotypic T cells taken from control sick rats did not proliferate against activated T cells and secreted mainly IFN-γ. In contrast, antiergotypic cells from CD25-DNA-protected rats proliferated against activated T cells and secreted mainly IL-10. Protective antiergotypic T ...

In a 1998 study, tritium concentrations in surface seawater and atmospheric water vapor (10 meters above the surface) were sampled at the following locations: the Sulu Sea, the Fremantle Bay, the Bay of Bengal, the Penang Bay, and the Strait of Malacca.[38] Results indicated that the tritium concentration in surface seawater was highest at the Fremantle Bay (approximately 0.40 Bq/liter), which could be accredited to the mixing of runoff of freshwater from nearby lands due to large amounts found in coastal waters.[38] Typically, lower concentrations were found between 35 and 45 degrees south latitude and near the equator. Results also indicated that (in general) tritium has decreased over the years (up to 1997) due to the physical decay of bomb tritium in the Indian Ocean. As for water vapor, the tritium concentration was approximately one order of magnitude greater than surface seawater concentrations (ranging from 0.46 to 1.15 Bq/liter).[38] Therefore, the water vapor tritium is not affected by ...

PY - 2014/6. Y1 - 2014/6. N2 - Introduction: More than 3 decades have passed since the first heterotopic heart transplantation (HHT) was reported. Nowadays, this surgical technique is used rarely, and only in patients who do not qualify for standard orthotopic heart transplantation (OHT). Current indications mainly comprise refractory pulmonary hypertension and a donor-recipient size mismatch (,20%). The objective of this study was to analyze the United States experience with HHT. Patients and Methods: The United Network for Organ Sharing (UNOS) database between 1987 and 2007 was analyzed. Patients who underwent heart transplantation were enrolled in this study. Patients with missing transplant dates or history of retransplantation were excluded. Results: A total of 41,379 patients underwent OHT and ...
Female Fischer 344 (F344) rats have been shown to display increased serotonin transporter (5-HTT) gene expression in the dorsal raphe, compared to female Lewis (LEW) rats. Herein, we explored, by means of synaptosomal preparations and in vivo microdialysis, whether central, but also peripheral, 5-HTT protein expression/function differ between strains. Midbrain and hippocampal [3H]paroxetine binding at the 5-HTT and hippocampal [3H]serotonin (5-HT) reuptake were increased in male and female F344 rats, compared to their LEW counterparts, these strain differences being observed both in rats of commercial origin and in homebred rats. Moreover, in homebred rats, it was found that these strain differences extended to blood platelet 5-HTT protein expression and function. Saturation studies of midbrain and hippocampal [3H]paroxetine binding at the 5-HTT, and hippocampal and blood platelet [3H]5-HT reuptake, also revealed significant strain differences in Bmax and Vmax values. Although F344 and LEW rats ...
purpose. Aronia crude extract (ACE) with high levels of polyphenol compounds has been reported to have antioxidative effects in vitro and in vivo. In this study, attention was focused on the antioxidant effect of ACE. The purpose of the present study was to investigate the effect of ACE on endotoxin-induced uveitis (EIU) in rats. In addition, the endotoxin-induced expression of the inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 proteins was investigated in a mouse macrophage cell line (RAW 264.7) treated with ACE in vitro, to clarify the anti-inflammatory effect.. methods. EIU was induced in male Lewis rats by a footpad injection of lipopolysaccharide (LPS). Immediately after the LPS inoculation, 1, 10, or 100 mg ACE or 10 mg prednisolone was injected intravenously. After 24 hours, the aqueous humor was collected from both eyes, and the number of infiltrating cells, protein concentration, nitric oxide (NO), prostaglandin (PG)-E2, and TNF-α levels in the aqueous humor were ...

Proceddings of the Society of Experimental Biology and Medicine 1989 May;191(1):47-54 The effects of additional but nontoxic amounts of vitamin A on susceptibility to salmonella infection was studied by comparing rates of bacterial clearance and phagocytosis. Forty-eight male Lewis rats were divided into a treatment group receiving a total of 6000 units of vitamin A palmitate weekly for 5 weeks and a control group was given an equal volume of saline. After completion of the treatment regimen, one-half from each group were infected intraperitoneally with 10(5) Salmonella typhimurium; the other half received intraperitoneal injection of saline. At this time no differences in weight gain were noted and all animals were sacrificed within 2 weeks. At 72 hr after bacterial challenge, all saline-treated control animals displayed bacteremia. Cultures of liver and splenic homogenates were positive in 89 and 100% of infected control animals vs 0 and 44% for treated animals during the first week of ...
Background. Chronic kidney disease (CKD) is an important risk factor for cardiovascular disease (CVD). Increased oxidative stress plays a role in the pathogenesis of CVD in CKD patients. The oral charcoal adsorbent AST-120 attenuates the progression of CKD possibly by removing uraemic toxins such as indoxyl sulfate (IS), and reduces oxidative stress. We investigated the relationship between oxidative stress and cardiac damage in CKD and its prevention by AST-120.. Methods. Male Lewis rats were administered adriamycin at 8 weeks of age, and the right kidney was removed at 12 weeks of age. From 14 weeks of age, the rats were treated daily with AST-120 (n = 8) or were untreated (control group, n = 8). At 34 weeks of age, the rats were killed and urinary and blood biochemical tests as well as cardiac histological analyses were performed.. Results. At 14 weeks of age, there were no significant differences in blood pressure, renal function (creatinine clearance: 1.54 ± 0.28 mL/min versus 1.60 ± 0.22 ...
Ductular reaction (DR) in bile duct ligated rats generally appears from 2nd day after biliary obstruction (BO). However, we show that increased amount of ductular profiles is evident already in 6 hours after BDL. The study aims to explain the origin of such an early DR in response to BO. Male Lewis rats were subjected to common bile duct ligation (CBDL) for 3, 6, 12 and 24 hours and sham operation. Liver samples were studied histologically, immunohistochemically (Ki67, pan-Cytokeratin /AE1 + AE3/ and OV-6) and by immunoblotting analyses. It appeared that number of ductular profiles increase in timerelated manner after BO. These ductular profiles are formed by biliary epitheliocyte-like cells; No mitotic activity was revealed. Part of hepatocytes reveals pan-Cytokeratin positivity on 12 and 24 hours after BO. Total cytokeratins content at 24 hours after CBDL was 37% higher in comparison with control data. The significant increase was observed for the cytokeratins with molecular weights: 61, 56 ...

The acute pulmonary responses after exposure to sulfur and nitrogen mustards are well documented whereas the late pulmonary effects are not. With a novel focus on the immune system this paper investigate whether late phase pulmonary effects developed in rats exposed to the nitrogen mustard melphalan are linked to the acute responses and whether the reactions are genetically regulated. The DA rat strain was used to establish a lung exposure model. Five other inbred rat strains (PVG, PVG.1AV1, LEW, WF and F344) were compared within the model at selected time points. All rat strains displayed a biphasic pattern of leukocyte infiltration in the lungs, dominated by neutrophils 2 days after exposure and a second peak dominated by macrophages 29 days after exposure. The number of macrophages was higher in the DA rat compared with the other strains. The infiltration of lymphocytes in the lungs varied in both time of appearance and magnitude between strains. The quantity of collagen deposition in the ...
If you can feel your pancreas dancing, the music is swinging. The quote comes from Bob Leary, banjoist/guitarist on this session. The visceral aspect is hard to prove, but his musical assessment is quite accurate. Cornetist Lew Green and clarinetist Joe Muranyi, who have individually accumulated many decades of touring and recording world-wide, even working as sidemen in the same bands, finally pool their Traditional talents as co-leaders, and the result is often authentic, vintage Dixieland. What gives it authenticity right at the outset, Oriental Man, is the bouncy sound of Vince Giordanos bass sax, plus the firm stride backing of pianist Jeff Barnhart. Guitarist Leary, who approaches his instrument with the same percussiveness as the banjo, also contributes a fine solo. The track has a joyous retro feel to it ...

AU - Christadoss, P.. AU - Krco, C. J.. AU - Lennon, V. A.. AU - David, C. S.. PY - 1981. Y1 - 1981. N2 - Autoantibodies to acetylcholine receptors (AChR) are demonstrable in approximately 90% of patients with acquired myasthenia gravis (MG) and are the major pathogenic cause of the defect in neuromuscular transmission that is characteristic of MG. Experimental autoimmune myasthenia gravis (EAMG) can be induced in animals by immunization with AChR and adjuvants. Induction of EAMG and of autoantibodies to AChR is T cell dependent. Studies in congenic mice revealed that susceptibility to EAMG is linked to the major histocompatibility complex. The lymphocyte proliferative response to AChR is controlled in congenic mice by gene(s) within the 1-A subregion. In this communication we present evidence that proliferation of ...

The lymphocyte function-associated antigen 1 (LFA-1) is a member of the beta2-integrin family and plays a pivotal role for T cell activation and leukocyte trafficking under inflammatory conditions. Blocking LFA-1 has reduced or aggravated inflammation depending on the inflammation model. To investigate the effect of LFA-1 in myocarditis, mice with experimental autoimmune myocarditis (EAM) were treated with a function blocking anti-LFA-1 antibody from day 1 of disease until day 21, the peak of inflammation. Cardiac inflammation was evaluated by measuring infiltration of leukocytes into the inflamed cardiac tissue using histology and flow cytometry and was assessed by analysis of the heart weight/body weight ratio. LFA-1 antibody treatment severely enhanced leukocyte infiltration, in particular infiltration of CD11b+ monocytes, F4/80+ macrophages, CD4+ T cells, Ly6G+ neutrophils, and CD133+ progenitor cells at peak of inflammation which was accompanied by an increased heart weight/body weight ratio. Thus,
We report the case of a patient with giant cell myocarditis who was bridged to transplantation with mechanical circulatory support and developed a fatal perioperative hyperacute rejection. The patient had received abundant transfusions that had raised her anti-HLA antibody titers. The cross-match test was positive. No pre-transplantation immunosuppressive therapy had been administered given concomitant infection. The severity and acuteness of the rejection in this case likely reflect the combined effect of preformed anti-HLA antibodies in the context of an active organ-specific immune process at the time of transplantation. This case raises the questions of the need for intensive immunosuppressive therapy before transplantation in giant cell myocarditis and of the management of patients with positive cross-match in the context of a giant cell myocarditis.

This study was conducted to investigate therapeutic value of a soluble tumor necrosis factor-alpha (TNF-alpha) receptor, etanercept, in a rat model of endotoxin-induced uveitis (EIU). Forty-two inbred male Lewis rats were divided into seven equal groups. 200 mug of Escherichia coli 055:1355 lipopolysaccharide, (LPS) was injected in one hind footpad of the Groups 2, 3, 4, 5, 6, and 7 rats. Group 5, 6, and 7 rats also received subcutaneous etanercept 24 hr prior to LPS injection at a dose of 0(.)4 mg kg(-1). Group 1 rats were used as controls. Eight, 24, and 48 hr after treatment clinical uvetis scores (miosis, iris hyperemia, and hypopyon) were assessed by a masked observer and the rats were euthanized. Neutrophil leukocytes, CD8 +, CD4 +, and CD45RO + cells in the anterior uveal tissue were counted either after hematoxylin-eosin or monoclonal antibody staining. TNF-alpha. levels were also measured in the aqueous humor samples by an ELISA method. Etanercept treatment significantly improved ...

Introduction: Chronic allograft nephropathy is characterized by arterial remodeling, tubular atrophy, graft fibrosis, and renal dysfunction. Its pathogenesis is poorly understood and no therapies are available. Nestin, a constituent of intermediate filaments, is a marker of progenitor cells which may contribute to chronic allograft remodeling. Here, we test the hypothesis, that Nestin is over-expressed in renal allografts during the development of chronic nephropathy.. Materials and methods: Renal transplantation was performed in the allogeneic Fischer 344 to Lewis rat strain combination. Isogeneic transplantation was done in the Lewis rat and untreated Lewis rats served as controls. Nestin-expression was investigated by real-time RT-PCR, Westernblotting and immunohistochemistry in controls and in grafts on days 9 and 42 post-transplantation (n = 4 per group).. Results: On histological sections of untreated control kidneys, Nestin-immunoreactivity was detected in all glomeruli and in very few ...

Administration of autoantigens under conditions that induce type 2 immunity frequently leads to protection from T cell-mediated autoimmune diseases. Such treatments, however, are inherently linked to the induction of IgG1 Abs and to the risk of triggering anaphylactic reactions. We studied the therapeutic benefit vs. risk of immune deviation in experimental allergic encephalomyelitis of SJL mice induced by MP4, a myelin basic protein-proteolipid protein (PLP) fusion protein. MP4 administration in IFA induced type 2 T cell immunity, IgG1 Abs, and experimental allergic encephalomyelitis protection, and all three were enhanced by repeat injections. Despite high Ab titers, anaphylactic side reactions were not observed when MP4 was repeatedly injected in IFA or as soluble Ag s.c. In contrast, lethal anaphylaxis was seen after s.c. injection of soluble PLP:139 - 151 peptide, but not when the peptide was reinjected in IFA. Therefore, the Ab response accompanying the immune therapy constituted an ...

The purpose of this study was to test the concept of a tolerogenic vaccine. The prediction was that a fusion protein containing a tolerogenic cytokine and the major encephalitogenic determinant of GPMBP (i.e., the NAg) would represent a qualitatively superior tolerogen compared with Ag alone. The covalently linked cytokine was predicted to provide two critical activities. First, the cytokine was predicted to bind the respective receptors on particular subsets of APC and condition those APC to express tolerogenic, anti-inflammatory, or inhibitory activity. Secondly, the binding of the cytokine domain to the cytokine receptor on those APC was predicted to target the covalently tethered Ag to the MHCII Ag processing pathway of those APC. Such a mechanism would ensure presentation of the covalently tethered NAg predominantly on cytokine-conditioned APC. Six cytokines were tested as potential candidates, including IL1-RA, IL-2, IL-4, IL-10, IL-13, and IL-16. IL-1RA and IL-16 were predicted to have ...
