    Description: Patients who suffer from stroke or infantile cerebral palsy often develop spastic impairments. The knowledge about the recruitment of motor units and firing patterns in spastic muscles is very little. In clinical practice invasive measurement techniques are used for achieving information about single motor units. These methods are limited in their reliability and reproducibility. A non-invasive method, the high spatial resolution electromyography (HSR EMG), is used as an alternative approach to measure the activity of single motor units. The HSR EMG allows the detection of recruitment strategies of motor units in spastic muscles. Additionally the HSR EMG allows the distinction between the activation patterns of spasticity and peripheral nerve denervation.

    Title: Nachweis von oxidativem Stress bei Hämodialyse Patienten : Evidence of Oxidative Stress in Hemodialysis Patients

    Description: Patients with end stage renal failure and especially hemodialysis patients show an increase of cardiovascular mortality. The hight mortality is excessive increased as if its only to explain by traditional risk factors for cardiovaskular diseases. Increased Oxidative Stress is one of the most important not-traditional risk factors for this patients. It is leading to oxidative changes in the structure of proteins, lipids and amino acids. This changes are in turn responsible for the formation of arteriosclerotic lesions and in order that for cardiovascular disease. Oxidative Stress is state with of an imbalance between the production of reactive oxygen species and antioxidative defence mechanisms. In this paper we investigated the total antioxidant capacity as a entity of the antioxidants in plasma. We used the Total Antioxidant Status Assay Kit in which the oxidation of azino-di[3-ethylbenz- thiazoline sulphonate is measured by a spectrophotometer. Hemodialysis patients show compared to a healthy control group a significantly increased oxidative capacity (1,015 ± 0,021 mmol/l, n=123 vs. 0,762 ± 0,0344 mmol/l, n=40) The antioxidant capacity in plasma declined significantly during a single dialysis therapy. Furthermore we found a positive correlation between an increased efficiency of dialysis, measured by Kt/Veq, and the decrease of antioxidant capacity. Beyond this we investigated the intracellular concentration of 5 different antioxidatively acting enzyms. First enzym is the rhodanese, a thiosulfat-sulfurtransferase. It catalyzes the conversion of cyanide and toxic sulfur emissions in less toxic sulfur emissions. Then we had a look to the nNO- synthase (nNOS), to the superoxide dismutase SOD1 and SOD2 plus the glutathionperoxidase (GPx). We investigated the expression of the named enzyms in monocytes from healthy control subjects and from age-matched patients with end stage renal failure at the start and at the end of a hemodialysis session by using in-cell Western assay with specific primary and fluorogenic secondary antibodies. The intracellular concentrations of rhodanese (befor HD 0,3830 ± 0,01260 arbitrary units vs. after HD 0,4089 ± 0,01468 arbitrary units; n=36; p
