The present study was undertaken to explore the protective effects of tuberous root extract of Pueraria tuberosa on chronic foot shock stress (CS) induced physiological, neurobehavioral and neuropathological alterations. Male Wistar rats (120-150 g) were divided into seven groups, consisting of ten animals in each. Group I served as normal, group II as positive control, while group III-VII as test drug treated.

Puerarin (PU) and curcumin (CU), used commonly in traditional Chinese medicine and Ayurveda, have been shown to possess potent anti-inflammatory, anti-oxidation, and neuro-protective properties. Despite the experimental success of CU and PU in in vitro and animal models, their effectiveness has not yet been demonstrated in clinical trials, possibly because of their poor bioavailability.

BACKGROUND: The onset of menopause marks a pivotal time in which the incidence of hypertension and of cardiovascular disease (CVD) begins to increase dramatically in women. Before menopause, the incidences of these diseases are significantly lower in women than in age-matched men. After menopause, the rates of these diseases in women eventually approximate those in men. The loss of endogenous estrogen at menopause has been traditionally believed to be the primary factor involved in these changes.

Isoflavones have potential for preventing and treating several chronic health conditions, such as osteoporosis, cardiovascular disease, and cancer. In this study, radiolabeled isoflavones were recovered from kudzu (Pueraria lobata) root cultures after incubation with uniformly labeled (14)C-sucrose in the culture medium for 21 days. Approximately 19% of administered label was recovered in the isoflavone-rich dried extracts of kudzu root cultures (90.2 microCi/g or 3.3 MBq/g extract).

INTRODUCTION: Reduction of ovarian estrogen secretion at menopause increases net bone resorption and leads to bone loss. Isoflavones have been reported to protect bone from estrogen deficiency, but their modest effects on bone resorption have been difficult to measure with traditional analytical methods.

The present study tested the long-term effects of dietary kudzu root extract supplementation on the regulation of arterial pressure, plasma glucose, and circulating cholesterol in stroke-prone spontaneously hypertensive rats (SP-SHR). Female SP-SHR were maintained for 2 months on a polyphenol-free diet, with or without the addition of 0.2% kudzu root extract. Half of the rats in each diet group were ovariectomized, whereas the other half remained intact.

Alcoholism, Clinical and Experimental Research

BACKGROUND: Isoflavone administration in the form of a purified extract from the herbal medication kudzu root has been shown to reduce, but not eliminate, alcohol consumption in alcohol-abusing and alcohol-dependent men. The precise mechanism of this action is unknown, but 1 possible explanation for these results is that the isoflavones in kudzu might actually increase the intensity or duration of alcohol's effects and thus delay the desire for subsequent drinks. This study was designed to test this hypothesis.

Long-term estrogen deficiency increases the risk of obesity, diabetes and metabolic syndrome in postmenopausal women. Menopausal hormone therapy containing estrogens might prevent these conditions, but its prolonged use increases the risk of breast cancer, as wells as endometrial cancer if used without progestins. Animal studies indicate that beneficial effects of estrogens in adipose tissue and adverse effects on mammary gland and uterus are mediated by estrogen receptor alpha (ERα).

OBJECTIVE: We previously demonstrated that short-term treatment with a standardized kudzu extract (NPI-031) reduced alcohol drinking by men and women in a natural setting. The present study was conducted in nontreatment-seeking heavy drinkers to assess the safety and efficacy of 4 weeks of kudzu extract in an outpatient setting. METHOD: This randomized between-subject, double-blind, placebo-controlled study involved 2 weeks of baseline, 4 weeks of treatment, and 2 weeks of follow-up.

The incidence of type 2 diabetes and metabolic disease is rapidly increasing, but effective therapies for their prevention and treatment have been poorly tolerated or minimally effective. In this study, chronic administration of kudzu root extract (8 months, 0.2%, w/w, in diet) decreased baseline fasting plasma glucose (183±14 vs. 148±11 mg/dl) and improved glucose and insulin tolerance in C57BL/6J ob/ob mice (1.67±0.17 ng/ml [kudzu treated] vs. 2.35±0.63 ng/ml [control]), but such treatment did not alter these parameters in lean control mice.
