Sprague-Dawley female rats SBC-115076 Others inhibitor were maintained under controlled standard conditions of light and fed with conventional food of standard calcium content and no alfalfa or soybean components. Rats were randomized into four groups: Group A represented normal rats (sham operated) while three other groups were ovariectomized (OVX) and fed for three months as follows: standard food (group B), 6 mg/kg/day food mixed with RCE (Group C), or given 6 mg/kg/day of RCE plus a modified alkaline supplementation (BP) through a nasogastric tube at a dose of 16 mg (group D). The animals were killed 90 days after surgery. As compared to group B, RCE or RCE + BP
treatments brought about significantly higher level of estradiol and mitigated the weight loss of the uterus and improved maximum load of the femoral neck. Osteocalcin level showed an over 65% increase in group B but both RCE and RCE + BP treatments BI-D1870 PI3K/Akt/mTOR inhibitor prevented such abnormality with a significantly better result in RCE + BP group
which virtually normalized such parameter as well as urinary excretion of DPD. Group C and D reduced the over 20% loss of bone mineral density and bone mineral content/body weight ratio observed in untreated post-ovariectomy group. Untreated ovariectomy caused about 48% decrease of cancellous bone mass in the femoral neck while this abnormality was prevented at similar extent by both RCE and RCE + BP treatments. Ovariectomy determined an over 80% increase of bone alkaline phosphatase (BALP) level but both RCE and RCE + BP treatments significantly mitigated such variable. The BALP decrease yielded by the CBL0137 combined RCE + BP treatment was statistically lower than RCE alone. Taken together these data show that red
clover preparation in dosages amenable to clinical practice do improve OVX-induced osteoporosis while a mild metabolic alkalosis might further synergize some therapeutic aspects.”
“Plasma protein binding is an important factor that influences drug ADME. The aim of the present study was to analysis protein binding of sophoridine to rat plasma. A simple and specific HPLC method was developed for the determination of sophoridine in plasma protein binding. The method involved liquid-liquid extraction and a reversed-phase chromatographic separation with a mobile phase of acetonitrile-0.1 % phosphate buffer (containing 0.1 % triethylamine) (7: 93, v/v) and UV detection at 220 nm. The standard curve for sophoridine was liner over the concentration range of 0.2 to 15 mu g/mL. The intra-day and inter-day variations were less than 10 %. Ultrafiltration technique was applied to determining the protein binding of sophoridine in rat plasma after injection of sophoridine solution.
