Implantation of polypropylene mesh of a pore size of 3 mm in an onlay position is associated with a significant reduction of shrinkage in comparison to a 1 mm pore lightweight and 0.5 mm pore heavyweight mesh. A pore size increase to 3 mm is not sufficient for an improvement of mesh-tissue complex elasticity in comparison to a 1 mm pore lightweight and 0.5 mm heavyweight mesh. Polypropylene mesh with enlarged pores to 3 mm is associated with a similar strength of FBR in mesh pores and a reduced foreign body granuloma in comparison to a 1 mm pore lightweight and 0.5 mm pore heavyweight mesh.
The knitted PTFE mesh induces fewer intraperitoneal adhesions of lower density than the light-weight polypropylene mesh. The strength of the knitted PTFE mesh fixation to the abdominal wall is comparable with that of the light-weight polypropylene mesh, but the shrinkage is greater. The biocompatibility of the knitted PTFE mesh is comparable with that of the light-weight polypropylene implant.
We studied the influence of power frequency and vector of EMF on avian and mammalian embryogenesis at a high level of magnetic induction (10 mT professional exposures and using therapeutic devices of Czech provenance) and at a low level (6 μΤ -environmental occurrence). No significant alterations of either avian or mammalian embryogenesis were found after repeated exposures to 50 Hz MF at 10 mT or 6 μΤ, nor with different vectors.
The effect of electromagnetic field (EMF) 50 Hz, 10 mT, on the tissue retention of radiotoxic polonium-210 and thorium-234 was studied in a rat model. Regarding 210Po in the ionic state, small but significant effects were obtained by exposure of rats to EMF either before the intravenous injection of 210Po (pre-exposure) or after the rats had already been injected with 210Po (post-exposure). When compared with control values, pre-exposure to EMF caused a significant 28% decrease in the retention of 210Po in the skin and a 10% decrease in total 210Po retention in the investigated tissues. Relative to controls, post-exposure resulted in a 131% increase in 210Po retention only in the thymus. Regarding carrier-free 234Th in the ionic state, both types of EMF exposure caused a substantial increase in 234Th retention in the liver and spleen and a decrease of 234Th in the bones. A different effect of EMF on the retention of 234Th in the body was obtained when the mass of thorium was increased by adding as carrier 232Th (50 micrograms kg-1 body mass). With pre-exposure, a significant 10% decrease in the high retention of 234Th in the liver (77% of injected radioactivity) was observed. On the other hand, with post-exposure no significant changes in retention of 234Th were found in the tissues.
The aim of this study was to detect the effect of a magnetic field on manganese transport into rat brains. An experimental group of Female Wistar rats was given 0.48 mg Mn2+ per kg body weight intratracheally twice a week for 3 months and simultaneously exposed to a magnetic field: B = 10 mT, f = 50 Hz for 1 hr. Rats in one control group of rats received the same dose of manganese as the experimental group but were not exposed to the magnetic field. Rats in a second control group had neither exposure to manganese nor exposure to the magnetic field. After the last dose, all rats were sacrificed and their brains and other tissues were analyzed for manganese content. The results indicated that the magnetic field had a positive effect on increasing the manganese content in the brains of rats in the experimental group relative to those of the control groups. Visual evoked potentials (VEP) measured at the end of the exposure periods on randomly selected experimental and control rats showed a shortened but not statistically significant latency of the P1 peak of VEP in rats that had been exposed to both factors but not in control rats.
CitationJ Jerabek, A Bordon, R Pineda. Complex balneo-physiatric treatment in fibromyalgia: A pilot study.Abstract 19 patients meeting CDC criteria for fibromyalgia (FM) were treated. The treatment consisted of warm water hydrotherapy performed in bathtub with hydrojets, dry CO2 bathes, pulsed magnetotherapy, ultrasonotherapy applying capsaicin ointment and manual techniques for 2 weeks. All the mayor fibromyalgia impact questionnaire, McGill short questionnaire and additional variables improved at high statistical significance level. Up to date the worst improvement period lasted for 4 months. The most difficult cases were those, where cervical spondylitis was diagnosed together with FM. The mechanism of action of factors applied is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
