Objective: We compared the immunologic characteristics of mycoplasma pneumoniae-triggered Kawasaki disease (MP-KD) with Kawasaki disease (KD) not associated with mycoplasma pneumoniae (MP), with mycoplasma pneumoniae-triggered Henoch-Schönlein purpura (MP-HSP), and with healthy controls.

Methods: Complement levels, cellular and humoral immunity were assessed in KD, in MP-KD, in MP-HSP, and in healthy children.

Results: Of 622 children with KD, 74 had MP-KD.

Background: This study aimed to investigate the antioxidant and hypolipidaemic activities of an ethanol extract of Lethariella cladonioides (Nyl.) Krog (EE) and to characterise its chemical constituents.

Results: Nine phenols were identified as canarione, thamnolic acid, squamatic acid, vermicularin, norstictic acid, baeomycesis acid, lecanoric acid, barbatinic acid and usnic acid from analysis of EE by using high-performance liquid chromatography with a diode array detector-mass spectrometry.

3 Beta-acetoxy-(20S, 22E)-dammaran-22-en-25-ol, a new triterpene, was isolated along with five known triterpenes (ursolic acid, oleanolic acid, betulinic acid, 3-epiocotillol acetate, and dimmarenediol II acetate), and alpha-D-glc and sucrose from Radix Ranunculus ternati All of them, except oleanolic acid and alpha-D-glc, were isolated from the family of Ranunculaceae for the very first time, and the NMR data of sucrose was first described. In addition, the absolute configurations of alpha-D-glc and the glucose component of sucrose were determined.
