Alleviation of Cedar Pollen Induced Allergic Symptoms by Orally Taken Superfine Beta-1,3-Glucan
Intravenous- injection of beta-1,3-glucan in human is known to induce T helper type 1 response, while oral uptake did not. It was examined whether superfine dispersed beta-1,3-glucan (SDG) contrived to absorbed by intestinal mucosa would alleviate allergic symptoms by per-oral ingestion

|Official Title:||Alleviation of Cedar Pollen Induced Allergic Symptoms by Orally Taken Superfine Beta-1,3-Glucan - A Double-Blind Randomized Study|
- Symptoms were assessed clinically by score on a allergic symptom rating scale.
- Total IgE and allergen specific IgE were measured.
- The binding capacity of beta-1,3-glucan to peripheral CD14+ cells were assessed.
|Study Start Date:||January 2004|
|Estimated Study Completion Date:||June 2004|
Beta-1,3-glucan made from Japanese mushroom is commercially available for healthy foodstuffs. Allergy patients were orally administrated either SDG (n=30) or non-dispersed beta-1,3-glucan (NDG, n=30) and allergic symptoms were assessed clinically, by the double-blind, placebo-controlled, randomized study
