BACKGROUND The use of medicinal herbs whose efficacy and toxicities are not known by HIV-positive people in Lesotho is a threat to the effectiveness of antiretroviral treatment. This study explored some medicinal herbs used by HIV-positive people in Lesotho and the reasons for their use. METHODS This was a cross sectional study based on a questionnaire distributed to purposively-sampled HIV-p...

BACKGROUND Within the GABA(A)-receptor field, two important questions are what molecular mechanisms underlie benzodiazepine tolerance, and whether tolerance can be ascribed to certain GABA(A)-receptor subtypes. METHODS We investigated tolerance to acute anxiolytic, hypothermic and sedative effects of diazepam in mice exposed for 28-days to non-selective/selective GABA(A)-receptor positive all...

In vitro mitogenic activity of 16 herbs and 3 Kampo (herbal medicine) formulae have been reported in experimental studies. It is not known how many herbs and Kampo formulae in total have mitogenic activity. Lymphocyte transformation test (LTT) is generally utilized to diagnose drug-induced liver injury. In LTT, mitogenic activity is assessed by measuring 3H-thymidine incorporation. The objectiv...

Traditional Chinese medicine (TCM) has been used to treat tumors for years and has been demonstrated to be effective. However, the underlying molecular mechanisms of herbs remain unclear. This study aims to ascertain molecular targets of herbs prolonging survival time of patients with advanced hepatocellular carcinoma (HCC) based on network pharmacology, and to establish a research method for a...

Coptis herbs, which are important herbal medicinal materials, are the dried rhizomes of various plants. In China's herbal market, drying herbs can severely influence morphological markers such as shape, color, and odor, which make consumers difficult to precisely identify the herbs and effectively evaluate the quality. Here, we present the phylogenetic analysis of four Coptis herbal medicinal m...

Indiplon (NBI 34060; N-methyl-N-[3-[3-(2-thienylcarbonyl)-pyrazolo[1,5-alpha]pyrimidin-7-yl]phenyl]acetamide), a novel pyrazolopyrimidine and high-affinity allosteric potentiator of GABA(A) receptor function, was profiled for its effects in rodents after oral administration. In mice, indiplon inhibited locomotor activity (ED(50) = 2.7 mg/kg p.o.) at doses lower than the nonbenzodiazepine hypnot...

Object]: Detect whether different concentrations of Chinese herbs compound polysaccharides (CPS), astragalus polysaccharides (APS) and angeulica polysaccharides (ASP), epimedium herb polysaccharides (EPS) have effects on the immunity function of healthy Roman chicken. [Method]: 260 one-day-old chickens were divided into thirteen groups randomly, 20 birds each group. The physiological saline, Ch...

Research on core and effective formulae (CEF) does not only summarize traditional Chinese medicine (TCM) treatment experience, it also helps to reveal the underlying knowledge in the formulation of a TCM prescription. In this paper, CEF discovery from tumor clinical data is discussed. The concepts of confidence, support, and effectiveness of the CEF are defined. Genetic algorithm (GA) is applie...

The major objectives of this study were to provide a list of candidate antiaging medicinal herbs that have been widely utilized in Korean medicine and to organize preliminary data for the benefit of experimental and clinical researchers to develop new drug therapies by analyzing previous studies. "Dongeuibogam," a representative source of the Korean medicine literature, was selected to investig...
