The effect of ionising radiation, applied in the form of an electron beam, in the doses of 25, 100 and 400 kGy on the physical and chemical properties of thiamphenicol in solid phase has been studied by organoleptic analysis (form, colour, smell, solubility, clarity) and spectroscopic methods (UV, IR, EPR), chromatography (TLC), SEM observations, X-ray(More)
A 74-year-old patient, suffering for 20 years from polycythemia rubra vera, was treated with hydroxyurea for 2 years. Intensive xerosis (ichthyosis-like) and violaceous papules on the dorsal hand surfaces were observed. There was also reddish purple periorbital erythema resembling "heliotrope erythema". Such a disease pattern has been described as(More)
Adverse drug reactions (ADR) are the cause of hospital admissions for millions of patients every year and are believed to be a major problem in terms of morbidity and hospital expenses. ADR are characterized by exceptional variety, both considering pathomechanism and clinical symptoms. During the time period between 2000-2004 at the Department of(More)
Parenteral nutrition--a form of administering nutrients, electrolytes, trace elements, vitamins, and water--is a widely used mode of therapy applied in many diseases, in patients of different ages both at home and in hospital. The success of nutritional therapy depends chiefly on proper determination of the patient's energetic and electrolytic needs as well(More)
In the United States, the annual incidence of bladder cancer is approximately 70,000 new cases, with a mortality rate of approximately 15,000/year. The most common subtype (70%) of bladder cancer is superficial, namely hte non-muscle invasive disease form limited to the urothelium. The rate of progression and recurrence is up to 40 and 70%, respectively.(More)
The effect of ionizing radiation on florfenicol (FF), an antibiotic with wide antibacterial properties was investigated to determine whether it can be sterilized using high-energy radiation. FF was irradiated by E-beam radiation to doses of 25-800 kGy, and then changes in the physico-chemical properties were examined using chromatographic methods (TLC and(More)
Spectroscopic and chromatographic methods (HPLC, HPLC-MS, NMR) were used to observe, separate and identify products of radiolysis of thiamphenicol (TF), irradiated in the solid state at room temperature and atmospheric pressure with an electron beam from a linear accelerator to doses between 25 and 800 kGy. Nine products of radiolysis of thiamphenicol were(More)
