CONTEXT: Protein glycation is the major contributing factor in the development of diabetic complications. The antiglycation potential of medicinal plants provides a promising opportunity as complementary interventions for complications. OBJECTIVE: To investigate the antiglycation potential of 19 medicinal plants extracts using albumin by estimating different indicators: (1) glycation (early and late), (2) albumin oxidation, and (3) amyloid aggregation.

Many hypotheses of disease risk and prevention depend on inferences about the metabolic effects of fructose; however, there is inadequate attention to dose dependency. Fructose is proving to have bidirectional effects. At moderate or high doses, an effect on any one marker may be absent or even the opposite of that observed at very high or excessive doses; examples include fasting plasma triglyceride, insulin sensitivity, and the putative marker uric acid.

Compounds with anti-glutamatergic properties currently in clinical use for various indications (eg Alzheimer's disease, epilepsy, psychosis, mood disorders) have potential utility as novel treatments for alcoholism. Enhanced sensitivity to certain acute intoxicating effects (ataxia, sedative) of alcohol may be one mechanism by which anti-glutamatergic drugs modulate alcohol use.

The biosynthesis of the valuable sesquiterpene anti-malarial, artemisinin, is known to respond to exogenous sugar concentrations. Here young Artemisia annua L. seedlings (strain YU) were used to measure the transcripts of six key genes in artemisinin biosynthesis in response to growth on sucrose, glucose, or fructose.

In the present study, the effect of four Vajikaran Rasayana herbs on penile erection, sperm count, seminal fructose content in vivo and nitric oxide (NO) release in vitro was assessed. Lyophilised aqueous extracts of Asparagus racemosus Willd. (AR), Chlorophytum borivilianum Sant. F. (CB), Curculigo orchioides Gaertn. (CO), and Dactylorhiza hatagirea (D. Don) Soo (DH) were orally administered at 100 mg/kg body weight to Wistar strain male albino rats.

Sustained hyperglycemia is considered as a major cause of sexual and erectile dysfunction in human population. Curculigo orchioides (CO) is considered as a sexual tonic in Ayurvedic system of medicine with potent antioxidant and adaptogenic properties. The aqueous extract of the herb was evaluated for its effectiveness against streptozotocin-induced hyperglycemic stress and subsequent sexual dysfunction due to hyperglycemia in male rats. Six groups with eight male rats in each group were used for this study and the study was carried out for 28 days.

Asparagus racemosus Linn. (Fam. Liliaceae) is an ethno-pharmacologically acclaimed Ayurvedic medicinal plant. In the present study, aqueous extract of A. racemosus (ARC) was fractionated and screened for the polysaccharide fraction (ARP). The characterization was done by enzymatic, Size Exclusion, gas chromatography with flame ionization detector (GC-FID), high pressure anion exchange chromatography (HPAEC) and thin layer chromatographic analyses. Phyto-chemical evaluation confirmed the presence of 26.7% of 2→1 linked fructo-oligosaccharides (FOS).

Tinospora cordifolia is used in Ayurveda as "Rasayanas" to improve the immune system and the body resistance against infections. Polysaccharides are the main constituents which are considered to be responsible for immune enhancement. In this study, immunomodulatory activity of three polysaccharide enriched fractions was evaluated using the polymorphonuclear leukocyte function test. Sugar composition was determined by GC-MS analysis of the derivatised fractions. The active polysaccharide fractions mainly constitute glucose, fructose and arabinose as monomer units.

PURPOSE OF REVIEW: Based on interim results from an ongoing study, we have reported that consumption of a high-fructose diet, but not a high-glucose diet, promotes the development of three of the pathological characteristics associated with metabolic syndrome: visceral adiposity, dyslipidemia, and insulin resistance. From these results and a review of the current literature, we present two potential sequences of events by which fructose consumption may contribute to metabolic syndrome.

Diurnal patterns of circulating leptin concentrations are attenuated after consumption of fructose-sweetened beverages compared with glucose-sweetened beverages, likely a result of limited postprandial glucose and insulin excursions after fructose. Differences in postprandial exposure of adipose tissue to peripheral circulating fructose and glucose or in adipocyte metabolism of the two sugars may also be involved. Thus, we compared plasma leptin concentrations after 6-h iv infusions of saline, glucose, or fructose (15 mg/kg.min) in overnight-fasted adult rhesus monkeys (n = 9).
