OBJECTIVES To develop and validate a new risk-of-bias tool for nonrandomized studies (NRSs). STUDY DESIGN AND SETTING We developed the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS). A validation process with 39 NRSs examined the reliability (interrater agreement), validity (the degree of correlation between the overall assessments of(More)
Silibinin is the major active molecule of silymarin, the mixture of flavonolignans extracted from Cirsium japonicum. It has been used for the treatment of hepatitis and inflammation-related diseases. In the present study, the effects of silibinin on allergic inflammation and its signaling were investigated in the induced human mast cells. Cell growth(More)
The dried roots of Sophora flavescens Aiton (SFA) has been used in traditional medicine for treatment of inflammation, gastrointestinal hemorrhage, diarrhea, and asthma. In the present study, we investigated the effect of SFA on the inflammatory allergic reaction using human mast cell-1 (HMC-1). SFA (200mg/kg) inhibited the mast cell-mediated passive(More)
BACKGROUND Gyejibongnyeong-hwan (GJBNH) is one of the most popular Korean medicine formulas for menstrual pain of dysmenorrhea. The concept of blood stagnation in Korean medicine is considered the main factor of causing abdominal pain, or cramps, during menstrual periods. To treat the symptoms, GJBNH is used to fluidify the stagnated blood and induce the(More)
BACKGROUND This study aimed to examine the effect of apigenin on proliferation and apoptosis in HER2-overexpressing MDA-MB-453 breast cancer cells. MATERIALS AND METHODS The antiproliferative effects of apigenin were examined by proliferation and MTT assays. The effect of apigenin on apoptotic molecules was determined by western blotting. RT-PCR was(More)
Phytoestrogens have been demonstrated to inhibit tumor induction; however, their molecular mechanisms of action have remained elusive. The present study aimed to investigate the effects of a phytoestrogen, apigenin, on proliferation and apoptosis of the human epidermal growth factor receptor 2 (HER2)-expressing breast cancer cell line SKBR3. Proliferation(More)
Flavonoids are assumed to exert beneficial effects in different types of cancers at high concentrations. Yet, their molecular mechanisms of action remain unknown. The present study aimed to examine the effect of quercetin on proliferation and apoptosis in HER2-expressing breast cancer cells. The anti-proliferative effects of quercetin were examined by(More)
Objective. This study was a multicenter, randomized, double-blind, and controlled trial with two parallel arms: the GJBNH group and the placebo group. This trial recruited 100 women aging 18 to 35 years with primary dysmenorrhea caused by blood stagnation. The investigational drugs, GJBNH or placebo, were administered for two menstrual periods (8 weeks) to(More)
BACKGROUND Obesity, which is described as excessive or abnormal body fat, increases the risk of diet-related diseases. In Korea and around the world, the prevalence of obesity has grown annually from 1998 to 2008. This growth has continued despite various therapeutic efforts. The discovery of new and alternative treatments for obesity should be considered(More)
Objective. The purpose of this study was to assess the efficacy and safety of Taeeumjowi-tang (TJ001) as well as to estimate obesity-related factors. Methods. This was a 12-week trial with 5 visits. A total of 102 participants of both genders were randomized to either TJ001 (n = 57) group or the placebo group (n = 55). Subjects were administered 7 g of(More)
