ABSTRACT
Exercise is assumed to have a positive effect on migraine. However, none of the few studies on this topic can prove the expected positive influence of exercise. Therefore, the aim of this pilot study was to develop a training program suitable for migraine patients and to examine its effect on migraine. 16 patients were examined. 8 migraine patients completed a 10-week aerobic running exercise program consisting of 3 workouts per week. The program was developed by sports scientists especially to increase the fitness level. Physical fitness, i. e., physical working capacity, was assessed using a PWC 150 test. There was also a control group of 8 patients without any special physical training. Migraine patients of the exercise group showed both a reduction in the number of migraine days per month (p=0.048) and the intensity of the attacks (p=0.028). An increase in fitness level resulted in a lowered stress level. Stress strategies like "displacement activity" (r=-0.715; p=0.046), "looking for self-affirmation" (r=-0.742; p=0.035) and "feelings of aggression" (r=-0.802; p=0.017) were reduced. Increasing the level of fitness (PWC 150) is one predictor for migraine improvement (r=0.409, p=0.031). Aerobic exercise which leads to a better fitness level is an alternative therapy method for migraine.

Acrylamide in biological samples can be determined by gas chromatography with electron-capture detection after conversion to its 2,3-dibromopropionamide derivative. The derivatization is carried out in aqueous solution, plasma or tissue homogenates by ionic bromination and the reaction conditions and sample clean-up are described. The detection limit corresponds to 9.5.10(-12)g of acrylamide on column or 8.4.10(-9)g in the final biological extract (0.5 ml). The overall recovery of acrylamide spiked samples at the nanogram level exceeds 80%. It was found that the accumulation of free acrylamide in the sciatic nerve distal region of rats intoxicated with acrylamide was less than 2-8 ppm.

The response of the electron-capture detector to organic compounds is poorly defined, and the steroids are no exception to this observation. For those steroids which are naturally electron-capturing, the structures of the electrophores will be defined. Other steroids can be made electron-capturing by the formation of appropriate derivatives. Some new or infrequently used reagents for this purpose (flophemesyl ethers, t-bulflophemesyl ethers, pentafluorophenylhydrazone derivatives and halogen-substituted aromatic boronic acids) are described.
