The cross-reactivity between fruits dutas 0.5 mg, pollen purchase dutas 0.5mg without a prescription, and latex is also attributed to the highly conserved plant allergen profilin identified in all these different species ( 30). These results demonstrated a mutual boosting effect of pollen and latex sensitization in vivo, which may be seen also in polysensitized plant allergic patients. This study confirmed that mice stimulated with latex proteins develop a predominantly T H2 cytokine response. The results indicated that eosinophils and IgE antibodies play a major role in the immunopathogenesis of latex-induced allergy and anaphylaxis. In another study, latex-immunized mice evaluated by body plethysmography exhibited a significant change in pulmonary conductance (G L) and compliance (Cdyn) consistent with an asthma-like response. The latex-allergic response in this study is unique in that the direct challenge with latex antigen itself resulted in a significant airway response (128). The accumulated data from animal models suggest that the nature of sensitization in patients may be solely dependent on the type of antibody production and the pattern of cytokine expression by allergen-specific T lymphocytes ( 126,127,128 and 129). The studies using crude ammoniated latex, nonammoniated latex cytosol, and extracts demonstrated enhanced lymphoproliferative responses in latex sensitized patients ( 130). The distinct serologic patterns of patients against purified allergens were also reflected in their cell-mediated immune responses against these allergens. The monoclonal antibody affinity purified Hev b 3 exhibited proliferative responses in spina bifida patients, but not in health care workers ( 81). In another study, purified Hev b 1 induced lymphoproliferation in 52% of latex-allergic patients, compared with 25% of latex-exposed healthy subjects, suggesting that Hev b 1 is a relevant allergen in health care workers ( 133). Whereas, Hev b 2 showed stimulation in 56% patients, with more than 70% correlation between stimulation index and specific serum IgE binding ( 112). In a separate study, recombinant Hev b 5 demonstrated T-cell stimulation in five of six health care workers with latex allergy ( 134). In vitro study conducted using overlapping synthetic peptides of latex allergen Hev b 1 demonstrated that B lymphocytes of patients recognized several epitopes within the same allergen ( 137) (Table 31. In two separate studies, linear and conformational epitopes of prohevein have been identified; in both the studies, two linear epitopes were detected in the N-terminal region of Hev b 6 (114,141). B-cell epitopes of Hev b 6 specific for IgE antibody with sera from either latex-sensitized spina bifida patients or health care workers or common for both patients groups were reported.

The aspirin triad or occurrence of nasal polyps in association with asthma and aspirin sensitivity was first identified in 1911 ( 2). Nasal polyps represent a consequence of chronic mucosal inflammation; this condition also has been referred to as hypertrophic rhinitis. In most cases, nasal polyps arise from the middle meatus and clefts of the ethmoid region ( 3). Histologic sections of nasal polyp tissue exhibit infiltration with eosinophils, plasma cells, lymphocytes, and mast cells ( 4). Polypoid tissue is rich in ground substance containing acid mucopolysaccharide ( 5,6). Nasal polyps are diagnosed more frequently in men and during the third and fourth decades of life. Most clinical data indicate that there is no greater prevalence of nasal polyps among atopic compared with normal populations ( 2,7,8). A population-based study was conducted in Finland to determine the prevalence of asthma, aspirin intolerance, nasal polyposis, and chronic obstructive pulmonary disease in the adult population. The prevalence could be underestimated in that 8% of nasal polyp patients without histories of salicylate sensitivity exhibit aspirin intolerance when challenged with aspirin ( 10,11).
Blood transfusion buy generic dutas 0.5mg online, without which much major surgery is impossible buy discount dutas 0.5 mg online,became a reality in 1915 after work on dogs. Major heart surgery such as bypass techniques and heart transplants were developed in the 1960s through work on dogs and pigs. Kidney dialysis, which sustains the life of thousands of people if they are unable to receive kidney transplants, came about through work on rabbits and dogs. The drug heparin, to stop blood clotting during kidney dialysis and after surgery, was discovered in dogs and is still obtained from the liver and lungs of cows. Future treatments for multiple sclerosis, cystic fibrosis, spinal cord injury, Alzheimer s disease and a range of other conditions are being investigated with the help of animal studies. The questions being tackled,and the methods being used,are very different from those used 30 years ago.
