[Formation of oxalate in oxaliplatin injection diluted with infusion solutions].

Oxaliplatin use can cause acute peripheral neuropathy characterized by sensory paresthesias, which are markedly exacerbated by exposure to cold temperatures, and is a dose-limiting factor in the treatment of colorectal cancer.Oxalate is eliminated in a series of nonenzymatic conversions of oxaliplatin in infusion solutions or biological fluids.Elimination of oxalate from oxaliplatin has been suggested as one of the reasons for the development of acute neuropathy.

Determination of paroxetine in serum treated with simple pretreatment by pre-column high-performance liquid chromatography using 4-(5,6-dimethoxy-2-phthalimidinyl)-2-methoxyphenylsulfonyl chloride as a fluorescent labeling reagent.

The therapeutic drug monitoring of paroxetine could be used to optimize the pharmacological treatment of depressed patients. A simple and sensitive high-performance liquid chromatography procedure was developed for the determination of paroxetine in serum. After simple pretreatment of serum (50 μL) with acetonitrile and o-phthalaldehyde, paroxetine was derivatized with 4-(5,6-dimethoxy-2-phthalimidinyl)-2-methoxyphenylsulfonyl chloride at 70°C for 20 min in borate buffer (0.

[Comparison of hypersensitivity to branded and generic paclitaxel injections in rats].

The use of injectable generic antineoplastic agents has been increasing. Few studies have compared the quality and adverse reactions of generic and branded antineoplastic agents; and therefore, generic agents have not gained wide acceptance. Paclitaxel injections, which are used for treating solid cancers, are being marketed by some companies in Japan.

Sensitive determination of carnosine in urine by high-performance liquid chromatography using 4-(5,6-dimethoxy-2-phthalimidinyl)-2-methoxyphenylsulfonyl chloride as a fluorescent labeling reagent.

A simple and highly sensitive high-performance liquid chromatography procedure was developed for the determination of carnosine in urine. Carnosine was derivatized with 4-(5,6-dimethoxy-2-phthalimidinyl)-2-methoxyphenylsulfonyl chloride at 70 degrees C for 15 min in borate buffer (20 mmol l(-1), pH 9.0) to produce fluorescent sulfonamides.

[Management system of cancer chemotherapy regimens].

Cancer chemotherapy regimens which had been used at a ward and outpatient chemotherapy in various departments were collected and made available to everybody in October, 2003. However, it was difficult to manage cancer chemotherapy regimens in real time, from the viewpoint of risk management. Then, the Cancer Chemotherapy Center took the leading part and established a chemotherapy exploratory committee, which consists of 4 doctors, 2 nurses and 2 pharmacists, in June, 2006.

Possible relationships between plasma carbamazepine-10,11-epoxide levels and antimanic efficacy and side effects in patients with schizoaffective disorde.

We examined the relationships of plasma levels of carbamazepine (CBZ) and its two major metabolites, carbamazepine-10,11-epoxide (CBZ-E) and carbamazepine-10,11-diol (CBZ-D), with antimanic efficacy and side effects in patients with schizoaffective disorder. Positive relationships were found among plasma concentrations of CBZ-E and the degree of clinical improvement and side effects, whereas neither plasma CBZ nor CBZ-D levels were correlated with the degree of clinical improvement or side effects.

Interaction between fluvoxamine and cotinine or caffeine.

We examined the relationships between plasma fluvoxamine concentrations and plasma levels of cotinine and caffeine, respectively, under steady-state conditions in 30 patients who met DSM-IV criteria for a major depressive disorder and who were being treated with fluvoxamine. The daily dosages of fluvoxamine ranged from 50 to 200 mg (mean +/- SD 108 +/- 42 mg). Eleven patients were smokers and the remaining 19 were nonsmokers.
