Photometric Screening of Tetrabromobisphenol A in Resin Using Iron(III) Nitrate/Hexacyanoferrate(III) Mixture as a Colorimetric Reagent.

This study aims to provide a simple way to identify the possibility of tetrabromobisphenol A (TBBPA) present in polymers without the need for complicated separation with expensive equipment. Since the presence of phenolic hydroxyl groups is known to be identifiable by the reduction of Fe to Fe in a ferric coloring reagent, the possibility of TBBPA being present in a polymer can be screened by a photometric measurement. A mixed solution of iron(III) nitrate and potassium hexacyanide(III) acid was used as a ferric coloring reagent.

[A Survey on the Concurrent Administration of Erlotinib and Gastric Acid Suppressing Medications among Doctors:Concern for Drug Interaction].

Erlotinibis known as a key drug for the treatment of non-small-cell lung cancer. It is known to interact with gastric acid suppressing medications(AS). Concurrent administration of erlotinibwith AS is reported to decrease AUC and Cmax of erlotinib.

[Preventing dermatopathy of patients receiving cancer chemotherapy].

Anticancer drug-associated dermatopathy tends to be disregarded because of its small systemic influence. However, it may affect daily living activities, and mental distress due to its appearance may interfere with the continuation of therapy. In this study, we surveyed the state of skin care, and found that patients had anxiety over vomiting and depilation rather than dermatopathy.

[Analysis of a case of oxaliplatin - induced persistence sensory neuropathy].

Thirty-seven patients with advanced or recurrent colorectal cancer were treated with mFOLFOX6 or mFOLFOX6 with a Bevacizumab regimen between September 2008 and March 2009. Then, we evaluated persistent neuropathy using the National Cancer Institute Common Terminology Criteria for Adverse Events (ver. 3).
