Allergic conjunctivitis caused by sugi (Cryptomeria japonica D. Don) pollen out of season.
Allergic conjunctivitis caused by sugi pollen is considered to be strictly a "spring disease". However, a recent report indicated that sugi pollen is scattered not only in spring but in all seasons, especially in the autumn. We retrospectively determined the number of patients with allergic conjunctivitis caused by sugi pollen during each month for 3 consecutive years, and also investigated the...
متن کاملForecasting models for sugi (Cryptomeria japonica D. Don) pollen count showing an alternate dispersal rhythm.
BACKGROUND Pollen information is indispensable for allergic individuals and clinicians. This study aimed to develop forecasting models for the total annual count of airborne pollen grains based on data monitored over the last 20 years at the Mie Chuo Medical Center, Tsu, Mie, Japan. METHODS Airborne pollen grains were collected using a Durham sampler. Total annual pollen count and pollen coun...
متن کاملDNA variation in a conifer, Cryptomeria japonica (Cupressaceae sensu lato).
We investigated the nucleotide variation of a conifer, Cryptomeria japonica, and the divergence between this species and its closest relative, Taxodium distichum, at seven nuclear loci (Acl5, Chi1, Ferr, GapC, HemA, Lcyb, and Pat). Samples of C. japonica were collected from three areas, Kantou-Toukai, Hokuriku, and Iwate. No apparent geographic differentiation was found among these samples. How...
متن کاملIsolation and molecular characterization of single-chain Fv antibodies raised against pollen allergens from Japanese cedar (Cryptomeria japonica D. Don).
We report here the isolation and molecular characterization of single-chain Fv (scFv) antibodies raised against two major allergens, Cryj1 and Cryj2, in the pollen of Cryptomeria japonica by the phage display method. Recombinant phages that produced scFv antibodies that bound to Cryj1 or Cryj2 were isolated by selection with immobilized antigens in microtiter plates. After selection of six Cryj...
متن کاملPossible role of climate change in the pollen scatter of Japanese cedar Cryptomeria japonica in Japan
We conducted an atmospheric pollen survey using a Durham sampler from 1983 through 1998 in Toyama City, Japan. We investigated yearly changes in the pollen season of Japanese cedar Cryptomeria japonica and analyzed the relationships between climatic factors and changes in the pollen counts. The results were as follows: (1) The first day of the Japanese cedar pollen season advanced from mid-Marc...
