High serum levels of TNF-α and IL-6 predict the clinical outcome of treatment with human recombinant erythropoietin in anaemic cancer patients.

Background: A number of anaemic cancer patients are not responsive to treatment with recombinant human erythropoietin (rHuEPO). The aim of the present study is to investigate whether serum levels of tumour necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, IL-6 and additional laboratory parameters, together with clinical variables, can predict the clinical outcome of treatment with rHuEPO in anaemic cancer patients.

Patients And Methods: Thirty-five cancer patients and 25 healthy controls were enrolled in this study.

The confirmation and control of metabolic caffeine in standardbred horses after administration of theophylline.

The origin of caffeine detections in equine serum and urine after theophylline administrations was examined. Three different preparations containing theophylline were administered to standardbred mares. Both blood and urine samples were collected.

Monitoring furosemide in racehorses participating in an EIPH program.

Analytical procedures were developed to monitor furosemide concentrations in post-race serum and urine samples obtained from horses participating in an exercise-induced pulmonary haemorrhage (EIPH) program. High performance liquid chromatography with ultraviolet light detection proved a reliable, sensitive method for measuring urinary furosemide concentrations up to 12 h after administration of either 150 or 250 mg of the drug to race horses. However, this method was unreliable for determination of serum furosemide concentration.

Plasma elimination and urinary excretion of procaine after administration of different products to standardbred mares.

Plasma and urinary concentrations of procaine were examined in Standardbred mares after subcutaneous administration of various doses (80 mg to 1600 mg) of procaine hydrochloride. Regardless of dose, peak plasma procaine values occurred within 1 h, but remained detectable in a dose-dependent manner, with procaine present at 1 h with the 80 mg dose and 6 h at the 1600 mg dose. Similarly, peak urinary procaine concentrations were attained within 1.
