Several drugs, including aminoglycosides and platinum-based chemotherapy agents, are well known for their ototoxic properties. However, FDA-approved drugs are not routinely tested for ototoxicity, so their potential to affect hearing often goes unrecognized. This issue is further compounded for natural products, where there is a lack of FDA oversight and the manufacturer is solely responsible for ensuring the safety of their products. Natural products such as herbal supplements are easily accessible and commonly used in the practice of traditional eastern and alternative medicine...

This review looks into the herbs gingko biloba, polygala tenuifolia, and lycii fructus for their widely studied neuroprotective properties. Effects of the interaction between the herbs are studied by behavior tests to evaluate memory, and examination of signal transduction enzyme, major neurotransmitters, cell death and antioxidation. For 6-month treated mice, behavior showed shorter escape latency in the water maze and faster arrival time in a consolidated memory task. Immunochemistry showed evident increase in superoxide dismutase (SOD) activities in the prefrontal cortex, which implies protection against harmful free radicals during aging...

Tinnitus is a phantom perception of sound in the absence of overt acoustic stimulation. The focus of our attention is a combined therapy of tinnitus. In this prospective study (2013-2014) we evaluated the data of normal-hearing patients with tinnitus treated with various treatment modalities. In Group 1 we evaluated the data of 84 patients/124 ears after six weeks of treatment with betahistine dihydrochloride (72 mg). In Group 2, we evaluated the data of 36 patients/ 55 ears unimproved from Group 1 who were then treated for six weeks with hyperbaric oxygen (HBO₂) therapy combined with gingko biloba extract (120 mg)...

The interaction between cellulose and xylan is important for the load-bearing secondary cell wall of flowering plants. Based on the precise, evenly spaced pattern of acetyl and glucuronosyl (MeGlcA) xylan substitutions in eudicots, we recently proposed that an unsubstituted face of xylan in a 2-fold helical screw can hydrogen bond to the hydrophilic surfaces of cellulose microfibrils. In gymnosperm cell walls, any role for xylan is unclear, and glucomannan is thought to be the important cellulose-binding polysaccharide...

Amentoflavone is a bioflavonoid found in a variety of traditional Chinese medicines such as Gingko and Selaginella tamariscina. It has been reported that amentoflavone has anti-inflammatory, antioxidant, antiviral and anticancer effects. However, the effect of amentoflavone on osteogenic differentiation of human mesenchymal stem cells (hMSCs) has not been studied. In this study, we aim to explore the effect of amentoflavone on the proliferation and osteogenic differentiation of hMSCs. The results showed that amentoflavone significantly enhanced the proliferation, alkaline phosphatase (ALP) activity and mineralization in hMSCs...

AIM: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common genetic disorder, affecting nearly 400 million individuals worldwide. Whilst it is known that a number of drugs, foods and chemicals can trigger haemolysis in G6PD deficient individuals, the association between herbal and dietary supplements and haemolysis is less clear. The objective of this study was to evaluate the association between herbal or dietary supplements and adverse events in G6PD deficient individuals. METHODS: We searched fourteen electronic databases from their inception until November 2015 for articles describing the use of herbal or dietary supplements in G6PD deficient individuals...

A number of recent trials have demonstrated positive effects of dietary supplementation with the omega-3 polyunsaturated fatty acids (n-3 PUFAs), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) on measures of cognitive function in healthy young and older adults. One potential mechanism by which EPA, and DHA in particular, may exert these effects is via modulation of cerebral hemodynamics. In order to investigate the effects of DHA alone or provided as one component of a multinutrient supplement (also including Gingko biloba, phosphatidylserine and vitamins B₉ and B₁₂) on measures of cerebral hemodynamics and cognitive function, 86 healthy older adults aged 50-70 years who reported subjective memory deficits were recruited to take part in a six month daily dietary supplementation trial...

Tardive dyskinesia (TD) is a serious side effect induced by the long-term administration of typical antipsychotics. The pathophysiology of TD remains unclear, but experimental evidence suggests that neurodegeneration caused by free radicals may play an important role in TD development. S100B is considered a potential biomarker of structural neural and glial damage. This study investigated S100B expression in TD-related brain regions and assessed the effect of antioxidants Gingko biloba leaf extract (EGb761) and vitamin E (VE) on S100B in TD rats...

BACKGROUND: Intermittent claudication (IC) is a symptom of peripheral arterial disease (PAD) and is associated with high morbidity and mortality. Pentoxifylline, one of many drugs used to treat IC, acts by decreasing blood viscosity, improving erythrocyte flexibility and promoting microcirculatory flow and tissue oxygen concentration. Many studies have evaluated the efficacy of pentoxifylline in treating individuals with PAD, but results of these studies are variable. This is an update of a review first published in 2012...
