Treatment Overview. Brace (orthotic) treatment for scoliosis is used to prevent spinal curve progression and to maintain the appearance of the back. The goal of brace treatment is to prevent the curve from getting worse. Bracing does not correct a curve.
Slow-reacting substance of anaphylaxis. The slow-reacting substance of anaphylaxis or SRS-A is a mixture of the leukotrienes LTC4, LTD4 and LTE4. Mast cells secrete it during the anaphylactic reaction, inducing inflammation. It can be found in basophils.
However, anaphylactoid reactions, unlike anaphylactic reactions, may occur after the first exposure to a substance. Also, anaphylactoid reactions are not allergic reactions because immunoglobulin E (IgE), the class of antibodies involved in allergic reactions, does not cause them. Rather, the reaction is caused directly by the substance.
