Diclofenac is a non-steroidal anti-inflammatory agent used in degenerative joint disease, rheumatoid arthritis, and allied conditions.' Its commonest unwanted effects include gastrointestinal disorders, rashes, peripheral oedema, and abnormalities of serum transaminase activity. More rarely, melaena and haematemesis, myoclonic encephalopathy, and myoclonus of the lower limbs may occur.2 3 We re...

1. The serum ferments are practically unaltered by a primary injection of foreign protein. 2. During the course of sensitization the injection of the antigen is followed by the mobilization of a non-specific protease which increases in rapidity and intensity as the maximum period of sensitization is reached. 3. Acute shock is accompanied by: (a) The instantaneous mobilization of a large amount ...

From the experiments presented, it follows that the specific precipitation and the production of anaphylactic shock with certain azodyes, as described previously, is due to these substances themselves and is not dependent upon formation of azoproteins by interaction of the dyes with proteins in the test tube or the animal body. Besides these, some other azodyes which in our tests did not give p...

This paper reviews the mechanisms of anaphylactic shock in terms of the immunoglobulin and non-immunoglobulin triggering events, and the cellular events based on the rise in intracellular cyclic AMP and calcium that release preformed granule-associated mediators and the rapidly formed, newly synthesized mediators predominantly based on arachidonic acid metabolism. These primary mediators recrui...

BACKGROUND Epinephrine and more recently arginine vasopressin (AVP) alone or in combination have been proposed in patients with anaphylactic shock, but few experimental data exist. The authors investigated the effects of epinephrine only, AVP only, or epinephrine followed by AVP in a model of anaphylactic shock. METHODS Ovalbumin-sensitized Brown Norway rats were anesthetized, intubated, and ...
