Photoinduced Formation of Peroxide Ions on La2O3 and Nd2O3 under O2: Effects of Excitation Wavelength and Crystal Structure.

Photoinduced formation of peroxide ions on La2O3 and Nd2O3 under O2 was studied by in-situ microprobe Raman spectroscopy with attention focused on the effect of excitation wavelength and crystal structure on the O2(2-) formation. It was found that photoexcitations at 633, 532, 514, and 325 nm can induce O2(2-) formation over La2O3 at 450 °C. By contrast, photoexcitation at 785 nm does not cause formation of O2(2-) up to 500 °C.

[Long-term efficacy of Dermatophagoides pteronyssinus immunotherapy in patients with allergic rhinitis: a 3-year prospective study].

Objective: To evaluate the long-term efficacy of subcutaneous immunotherapy with Dermatophagoides pteronyssinus (DerP) in patients with allergic rhinitis.

Methods: Ninety-two patients with allergic rhinitis to DerP were randomly allocated to receive either specific immunotherapy (n = 46) or medical treatment (n = 46). Symptom and medication scores and skin response to Derp were assessed to evaluate the clinical efficacy in the baseline and after three years treatment.

[Association of single nucleotide polymorphisms of GATA3 with allergic rhinitis phenotypes in Chinese].

Objective: To evaluate the association between single nucleotide polymorphisms (SNP) of GATA3 and Chinese with allergic rhinitis.

Methods: This study included 109 patients with allergic rhinitis and 112 healthy control people. SNP of two loci with restriction fragment length polymorphism was detected, rs1269486 at promoter region and rs2229360 located 92 bp downstream of STOP codon.

[Effect of Pranlukast on tissue remodeling in experimental guinea pig allergic rhinitis model].

Objective: To explore the impact of Pranlukast in nasal mucosal remodeling in experimental allergic rhinitis.

Methods: Fourteen male guinea pigs were randomly divided into 3 groups: control group, ovalbumin (OVA) group and OVA + Pranlukast group. In the OVA group and OVA + Pranlukast group, OVA sensitized Hartley guinea pigs were exposured intranasally to OVA for a total of 12 weeks, the OVA + Pranlukast group received additional Pranlukast treatment from the second week to the 12th week.

[Nasal mucosa remodeling in guinea pig model of allergic rhinitis].

Objective: To explore the feature of nasal mucosa remodeling in experimental allergic rhinitis.

Methods: Twenty-four male Hartley guinea pigs (4 weeks, 250 -300 g) were randomly divided into four groups (control group and allergen exposure groups 1 - 3), each group had 6 guinea pigs. Allergen exposure animals were sensitized by intraperitoneal (ip) injection of ovalbumin (OVA).
