There is still debate over the optimal dosage, frequency and route of administration of interferon (IFN) beta in multiple sclerosis (MS). A prospective, non-randomized, comparative study was performed to evaluate differences in magnetic resonance imaging and clinical outcomes of two IFN beta-1a preparations (30mcg intramuscular [im] once-weekly [qw], AVO;(More)
Samples of longissimus and multifidi muscles at the thoracic and lumbar levels of the spine were examined histochemically on autopsy specimens from 21 adult male subjects (aged 22 to 46 years) and on biopsies from 17 adult patients during surgery for disorders of the lumbar intervertebral disc. In the superficial and deep thoracic muscles, 74% of fibres(More)
The size and the distribution of type I and tye II fibres was determined in the gluteus maximus (21 cases), gluteus medius (56 cases) and tensor faciae latae (27 cases) muscles of patients with osteoarthritis of the hip. The patients were of both sexes, aged between 37 and 64 years (younger group) and between 65 and 78 years (older group). Autopsy material(More)
Muscle samples obtained from distinct symmetrical sites of left and right vastus lateralis muscles from 10 young healthy males were analysed. A computer-aided system was applied for the determination of muscle fibre types I, IIA, IIB and IIC and for their quantitative analysis. No statistically significant differences were established regarding percentage(More)
The histochemical composition of the abductor hallucis (AH) muscle was investigated in 39 children with idiopathic clubfoot (CF), aged 0-11 years, and in 42 controls. In the youngest group of patients (0-2 years) the percentage of type 1 (slow twitch, tonic) fibers was significantly higher than in controls. In older groups, there was no difference between(More)
To prevent skin necrosis, fistula formation and rupture of the carotid arteries after RND, vascularization of the skin of the neck has been considered. The neck vessels (in cadavers) were injected with coloured media and specimens of the skin were cleared (Spalteholz method). The arteries supplying the skin of the neck followed in general an obviously(More)
The histochemical profiles of the bulbospongiosus (BS) and ischiocavernosus (IC) muscles were investigated on autopsy samples obtained from 13 men aged 18 to 33. Adenosine triphosphatase (ATPase) reactions were used for differentiation of muscle fibres into type 1 (slow twitch, tonic), and type 2 (fast twitch, phasic) and subtypes 2A, 2B, 2C. The activity(More)
The left ureter was isolated and its nutritive arteries interrupted in 43 rabbits. The blood flow in the isolated and in the control ureters was estimated intravitally by measuring the temperature in the wall of the ureters, and postmortally by counting the capillaries injected with India ink. The vascularization of the isolated ureter was lowered at 3 days(More)
