Identification of geranic acid, a tyrosinase inhibitor in lemongrass (Cymbopogon citratus).

Lemongrass is a popular Asian herb having a lemon-like flavor. Very recently, potent tyrosinase inhibitory activity has been found in lemongrass in addition to various biological activities reported in the literature. The aim of the present study is to identify the active compounds in the lemongrass.

IgA-associated glomerulonephritis with membranoproliferative glomerulonephritis-like pattern in two children.

In this article, we report two patients with IgA-associated glomerulonephritis with a membranoproliferative glomerulonephritis (MPGN) -like pattern. Both patients had nephrotic syndrome at onset. One patient was treated with high-dose alternate-day prednisolone (PSL), and the other with indomethacin and low-dose PSL.

Transthoracic Doppler assessment of coronary flow velocity reserve in children with Kawasaki disease: comparison with coronary angiography and thallium-201 imaging.

Objectives: The purpose of this study was to determine the feasibility of coronary flow velocity reserve (CFVR) measurement by transthoracic Doppler echocardiography (TTDE) in children with Kawasaki disease (KD).

Background: Doppler-derived CFVR is a reliable marker predicting the presence of myocardial ischemia.

Methods: We studied 49 patients (median age 11 years) with KD.
