Guggulsterone Attenuated Lipopolysaccharide-Induced Inflammatory Responses in Mouse Inner Medullary Collecting Duct-3 Cells.

Guggulsterone (GS) is a phytosterol that has been used to treat inflammatory diseases such as colitis, obesity, and thrombosis. Although many previous studies have examined activities of GS, the effect of GS on lipopolysaccharide (LPS)-induced inflammatory responses in mouse inner medullary collecting duct-3 (mIMCD-3) cells have not been examined. Therefore, here, we investigated the anti-inflammatory action of GS on mIMCD-3 cells exposed to LPS.

Protein Tyrosine Phosphatase 1B Inhibitors from the Roots of Cudrania tricuspidata.

A chemical investigation of the methanol extract from the roots of Cudrania tricuspidata resulted in the isolation of 16 compounds, including prenylated xanthones 1-9 and flavonoids 10-16. Their structures were identified by NMR spectroscopy and mass spectrometry and comparisons with published data. Compounds 1-9 and 13-16 significantly inhibited PTP1B activity in a dose dependent manner, with IC50 values ranging from 1.

Oryeongsan suppressed high glucose-induced mesangial fibrosis.

Background: The pathological change of kidney in diabetic nephropathy is represented hypertrophy, inflammation, and renal fibrosis. Oryeongsan, traditional oriental herbal formula, is widely used for the treatment of nephrosis, dropsy, and uremia. This study was examined whether Oryeongsan attenuate high-glucose (HG)-promoted rat mesangial cell fibrosis and matrix accumulation, major features of diabetic glomerulosclerosis.

Gal-geun-dang-gwi-tang improves diabetic vascular complication in apolipoprotein E KO mice fed a western diet.

Background: Gal-geun-dang-gwi-tang (GGDGT), an herbal medicine, is used to treat hypertension, stroke, and other inflammatory disorders in the clinical setting. Recently, GGDGT was recognized by the Korea Institute of Oriental Medicine. This study aimed to evaluate the effects of GGDGT in a diabetic atherosclerosis model using apolipoprotein E knockout (ApoE-/-) mice fed a Western diet.

Ethanol extract of Lycopus lucidus elicits positive inotropic effect via activation of Ca2+ entry and Ca2+ release in beating rabbit atria.

Lycopus lucidus Turcz has been widely used as a traditional Oriental medicine (TOM) in Korea and China and prescribed for the enhancement of heart function. However, the precise effects have yet to be defined. The purpose of the present study was, therefore, to address whether the ethanol extract of Lycopus lucidus Turcz (ELT) has a positive inotropic effect.

Effect of an Ethanol Extract of Scutellaria baicalensis on Relaxation in Corpus Cavernosum Smooth Muscle.

Aims of study. The aim of the present study was to investigate whether an ethanol extract of Scutellaria baicalensis (ESB) relaxes penile corpus cavernosum muscle in organ bath experiments. Materials and methods.

Effect of Cuscuta chinensis on renal function in ischemia/reperfusion-induced acute renal failure rats.

The kidneys play a central role in regulating water, ion composition and excretion of metabolic waste products in the urine. Cuscuta chinensis has been known as an important traditional Oriental medicine for the treatment of liver and kidney disorders. Thus, we studied whether an aqueous extract of Cuscuta chinensis (ACC) seeds has an effect on renal function parameters in ischemia/reperfusion-induced acute renal failure (ARF) rats.
