Summary
Oral administration of 50 mg tartrazine to 122 patients with a variety of allergic disorders caused the following reactions: general weakness, heatwaves, palpitations, blurred vision, rhinorrhoea, feeling of suffocation, pruritus and urticaria.
There was activation of the fibrinolytic pathway as shown by reduction of plas‐minogen with high pre‐kallikrein and low kallikrein values. Reduction in complement activity (CH50) was seen in three out of sixteen reactions.
The aim of the present work was to determine experimentally the prognostic value of reduced activity of serum acetylcholinesterase (ACE) in cases of acute myocardial infarction (AMI). In the first part of the research we studied the mechanism of this reduction by comparing the serum results with the levels of the enzyme in cardiac tissue in such cases. It was found that ACE activity is reduced in serum and also in cardiac tissue in AMI, in contrast to creatine kinase (CK) that is augmented in serum but reduced in cardiac tissue. This fact was interpreted as a "reduced cardiac flow of ACE," in contrast to the "augmented cardiac clearance of CK" in similar cases. In the second part of our research, 50 patients, admitted in our hospital for AMI, were examined and their blood analysed mainly for ACE and CK at brief intervals (every 2-3 days), during hospitalization, and thereafter every 1-2 weeks for 1-4 months. From the results of ACE activity it was possible to classify these variations into four groups, each of them having a defined prognostic value for the evolution of the AMI, a persistent reduced serum activity being interpreted as a bad, severe prognosis, with high morbidity or mortality (groups II and III). We suggest, therefore, that the determination of ACE in serum in cases of AMI, especially before discharge home of such patients, may be an additional useful laboratory test in such cases.
SUMMARY A patient with alpha heavy chain disease (aHCD), who showed an abnormal chromosomal marker (D14 q +) in 10 % of the bone marrow cells, is described. The mesenteric lymph nodes, which showed reactive hyperplasia in the first biopsy, transformed later to a malignant lymphoma and finally to a plasma cell tumour. The small intestine revealed villous atrophy, diminished crypts, and intact surface epithelium. The ultrastructure of the goblet and epithelial cells appeared to be normal, and the microvilli were preserved except for circumscribed areas of destruction. The lamina propria was heavily infiltrated with mononuclear cells, mainly mature plasma cells. Alpha heavy chains (xHC) were found in the patient's saliva.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
