The phenol-sulfuric acid method Selleckchem VX 770 was used to quantify polysaccharides, and the monosaccharide composition of the polysaccharides was determined by gas chromatography. Stepwise discriminant analysis was used to differentiate among the five closely related species based on the chemical composition analysis. This proved to be a simple and accurate approach for discriminating among these species. The results also showed that the polysaccharide content, the amounts of the four low molecular weight compounds, and the mannose to glucose ratio,

were important factors for species discriminant. Therefore, we propose that a chemical analysis based on quantification of naringenin, bibenzyl, and polysaccharides is effective for identifying D. officinale.”
“Objective. The authors performed phase I/II clinical trial to evaluate the toxicity and efficacy of carbon ion radiotherapy (C-ion RT) for locally advanced squamous cell carcinoma of the uterine cervix.\n\nMethods. Between April 2000 and January 2006, 22 patients for Protocol 9902 were treated with C-ion RT.

The number of patients with stage IIB, selleck IIIB, and IVA diseases was 1, 18, and 3, respectively. All patients had bulky tumors measuring 4.0-12.0 cm (median 6.2 cm). The whole pelvic dose was fixed at 39.0 GyE for 13 fractions, and additional 15.0 GyE for 5 fractions was given to the gross tumor volume (GTV) and surrounding tissues.

With regard to local boost, a dose-escalation study was planned for 2 fractions to GTV. Total selleck chemicals llc dose to the cervical tumor was 64.0-72.0 GyE for 20 fractions.\n\nResults. All patients completed the scheduled therapy and no patient developed Grade 2 or higher acute toxicity. There was no Grade 3 or higher late complications at each dose. The 5-year overall survival rate and local control rate were 50.0% and 68.2%, respectively. Seven out of the 16 patients who received 64.0-68.0 GyE developed local recurrences, but all patients who received 72.0 GyE maintained local control.\n\nConclusions. There were no severe acute or late complications in this trial. C-ion RT has the potential to improve the treatment for locally advanced bulky cervical cancer by applying a total dose of 72.0 GyE, with the results lending incentive to further investigations to confirm the therapeutic efficacy.

“We studied the dose-dependent cardiotoxic effect of propranolol. Intraperitoneal injection of propranolol in doses of 1 and 2 mg/100 g body weight produced a potent effect on central hemodynamics and myocardial contractility, impaired diastolic relaxation, and caused damage to cardiomyocyte membranes due to activation of free radical oxidation.
