Alzheimer's disease (AD) is a neurodegenerative disorder in which the death of brain cells leads to memory loss and cognitive decline. To reduce the death rate and improve the biological activity of neurocytes, neurotrophic factors (NTFs) exhibit therapeutic effect on AD. However, therapeutic

Twenty-four South African medicinal plants were screened against Candida albicans standard strain ATCC 10231 and two clinical isolates from a 5-month-old baby and an adult, in an attempt to find a traditional remedy to treat oral candidiasis, which is prevalent in HIV-patients. Allium sativum L. and

Recent advances in neuroscience have revealed a greater, in-depth understanding of the complexities associated with memory. Contemporary theories hold that an integral relationship between memory formation, stabilization and consolidation revolve around plasticity of neuronal networks. The

Crude extracts and fractions of five species of Polygala - P. campestris, P. cyparissias, P. paniculata, P. pulchella and P. sabulosa - were investigated for their in vitro antifungal activity against opportunistic Candida species, Cryptococcus gattii and Sporothrix schenckii with bioautographic and

This article provides an overview of the pharmacokinetic drug-drug interactions (DDIs) for agents prescribed for attention-deficit/hyperactivity disorder (ADHD). Polypharmacy in the treatment of patients with ADHD leads to high exposures to DDIs and possibly adverse safety outcomes. We performed a

Polygala tenuifolia Willdenow is a herb known for its therapeutic effects in insomnia, depression, disorientation, and memory impairment. In Alzheimer's disease (AD) animal model, there has been no report on the effects of memory and cognitive impairment. PSM-04, an extract from the root of

Sevoflurane is a widely used anesthetic. A series of recent studies have shown that exposure to sevoflurane at an early stage is a risk factor for the development of learning and memory dysfunction. Euxanthone is a xanthone derivative obtained from Polygala caudata. This study was designed to

OBJECTIVE The aim of this study was to investigate the cognition-enhancing activity and underlying mechanisms of a triterpenoid saponin (polygalasaponin XXXII, PGS32) isolated from the roots of Polygala tenuifolia Willd. METHODS The Morris water maze was used to evaluate the spatial learning and

Tenuigenin, a major active component of polygala tenuifolia root, has been used to treat patients with insomnia, dementia, and neurosis. In this study, we aimed to investigate the effects of tenuigenin on osteoclastogenesis and clarify the possible mechanism. We showed that tenuigenin inhibited

Amyloid beta-protein (A beta) is a pivotal pathological factor in Alzheimer's disease (AD). Tenuigenin, extracted from the Chinese herb Polygala tenuifolia, seems to ameliorate the reduction in cholinergic function on rat models induced by A beta. To examine this therapeutic effect, we tested

Estrogen deficiency is associated with cognitive impairment. Hormone replacement therapy (HRT) has proven to be effective in preventing and reversing the memory and learning deficiencies. However, conventional estrogenic treatment could increase the risks of breast cancer and venous thromboembolism.

In the last twenty years a considerable body of information has accumulated on the chemical constituents of Chinese herbs and their therapeutic potential. Our evaluation/systematic review [1, 2] of well-designed, randomized double blind controlled trials on Chinese herbal medicines beneficial for

Osteoarthritis (OA) is a chronic degenerative joint disease that has been shown to be closely related to the over expression of matrix metalloproteinases (MMPs). Polygalacic acid is a triterpene isolated from the root of Polygala tenuifolia Willd. In the present study, the anti-inflammatory effect

The effect of a kampo medicine, Ninjin-yoei-to (NYT; Ren-shen-yang-rong-tang in Chinese) on nerve growth factor (NGF) secretion from the cultured rat astrocytes was examined in vitro. When rat embryo astrocytes were cultured in the presence of NYT for 24 h, the amount of NGF in the medium was

BACKGROUND Improved therapeutics aimed at ameliorating the devastating effects of neurodegenerative diseases, such as Alzheimer's disease (AD), are pertinent to help attenuate their growing prevalence worldwide. One promising avenue for such therapeutics lies in botanical medicines that have been
