Responses to mite antigen and nonimmunological stimuli, substance P, of chopped fragments of nasal mucosae were studied from eleven patients with perennial allergic rhinitis who were sensitive to mite antigen.Amount of released histamine significantly increased by either stimulation.However, the release of leukotrienes(LTs) increased only by the stimulation of mite antigen, which correlated with that of histamine.By either stimulation, amount of histamine release tended to be higher in patients with severe nasal symptoms than in those with moderate nasal symptoms.Only by mite antigen stimulation, amount of the release of peptide LTs and LTB4 tended to be higher in patients with severe nasal symptoms.We concluded that the amounts of histamine and LTs released from nasal mucosa in allergic reaction were closely related with the severity of nasal symptoms in patients with allergic rhinitis.
