Five postlingually deaf patients (age range 28-58 years) with multichannel cochlear implants were examined with single photon emission tomography (SPECT) (triple-head rotating gamma camera). Changes in the regional cerebral blood flow (rCBF) after intravenous administration of technetium-99m ethyl cysteinate dimer (Tc-99m ECD) were assessed through a(More)
The revolutionary development of biotechnology-derived therapeutic proteins has provided the expected improvements in quality, purity and consistency, as demonstrated in recombinant human FSH (rhFSH). However, the development of urine-derived gonadotrophins has not always shown comparable improvements. More recently, highly purified urine-derived FSH(More)
The authors examined urine specimens from 30 patients with multiple myeloma (MM) to determine the usefulness of cytodiagnostic urinalysis in evaluating such patients. Nine patients had clinical evidence of renal failure. In six of these nine patients (67%), or 20% of all patients, the urine sediment contained unique "MM-casts." These were characterized by a(More)
BACKGROUND A commercial preparation of recombinant human chorionic gonadotrophin (r-hCG, Ovitrelle) was launched in 2001. Generally, hCG is available in two formats: human chorionic gonadotrophin (u-hCG), derived from the urine of pregnant females, and r-hCG produced by DNA based biotechnology. METHOD The analytical characteristics of a highly purified(More)
