Comparative study on high fat diet-induced 4-hydroxy-2E-nonenal adducts in the hippocampal CA1 region of C57BL/6N and C3H/HeN mice.

In the present study, we investigated the influences of a high fat diet (HD) fed for 12 weeks, on lipid peroxidation and antioxidant enzyme using 4-hydroxy-2E-nonenal (HNE)-modified proteins (HNE-mp) and Cu,Zn-superoxide dismutase (SOD1) in the hippocampal CA1 region (CA1) in C57BL/6N and C3H/HeN mice. Body weights and body weight gains were significantly higher in HD fed C57BL/6N mice than in low fat diet (LD) fed C57BL/6N and LD or HD fed C3H/HeN mice. In the HD fed C57BL/6N and C3H/HeN mice, HNE-mp immunoreactivity and protein levels were much higher than in the LD fed C57BL/6N or C3H/HeN mice.

Interaction between warfarin and Panax ginseng in ischemic stroke patients.

Background: Today, the combined use of Oriental herbal medicines and Western biomedical medicines has been a prevalent yet controversial practice. Case reports and healthy volunteer trials have had conflicting results on the effect Panax ginseng has on warfarin's pharmacologic action, some reporting a reductive and others a potentiating influence.

Objective: This study investigated the interaction between warfarin and P.

An alternative therapy for graves' disease: clinical effects and mechanisms of an herbal remedy.

Graves' disease, the most common cause of hyperthyroidism, is an autoimmune disorder. Antithyroid drugs have been selected as the first-line treatment of Graves' disease in Korea, Japan, and European countries. However, antithyroid drugs such as methimazole (MMI) and prophylthiouracil (PTU) have limitations in clinical applications because of their side effects.

Peroxisome proliferator-activated receptor-gamma Pro12Ala polymorphism is associated with the susceptibility to ischemic stroke in Taeeumin classified by Sasang medicine.

Background: Sasang constitutional medicine classifies mankind into four constitutional types according to individual psychologic and physical traits. We hypothesized that differences among constitutional types might be explained by genetic variations.

Methods: To evaluate the hypothesis, we determined the possible association in ischemic stroke patients (n = 134) of peroxisome proliferator-activated receptor (PPAR)-gamma with four constitutional types of Sasang medicine.

Susceptibility for ischemic stroke in Korean population is associated with polymorphisms of the interleukin-1 receptor antagonist and tumor necrosis factor-alpha genes, but not the interleukin-1beta gene.

Enhanced release of proinflammatory cytokines may contribute to the pathogenesis of ischemic stroke. Interleukin-1 receptor antagonist (IL-1Ra) is an anti-inflammatory cytokine, and tumor necrosis factor (TNF)-alpha and IL-1beta are proinflammatory cytokine. To determine the role of cytokines in genetic susceptibility to ischemic stroke, we genotyped ischemic stroke patients (n = 152) and the healthy control subjects (n = 165) for IL-1Ra, TNF-alpha and IL-1beta polymorphism by polymerase chain reaction-restriction fragment length polymorphism methods.

The inhibitory effects of aqueous extract of Magnolia officinalis on human mesangial cell proliferation by regulation of platelet-derived growth factor-BB and transforming growth factor-beta1 expression.

Mesangial cell (MC) proliferation, mediated by platelet-derived growth factor (PDGF)-BB, transforming growth factor (TGF)-beta1, and cyclin-dependent kinases (CDK), is the common feature of glomerulosclerosis. Magnolia officinalis, stem bark of Machilus thunbergii S., has multiple pharmacological effects.

Inhibitory effect of aqueous extract from the gall of Rhus chinensis on alpha-glucosidase activity and postprandial blood glucose.

The present study examined the inhibitory effect of aqueous extract from the gall of Rhus chinensis (AEGRC) on alpha-glucosidase activity, an enzyme responsible for digestion of carbohydrate to monosaccharides in the process of intestinal absorption. AEGRC inhibited Bacillus alpha-glucosidase acitvity with an IC(50) of 0.9 micro g/ml.
