Efficacy and tolerance of Harpagophytum extract LI 174 in patients with chronic non-radicular back pain.

The aim of this open, multicentre study was to evaluate the clinical effectiveness and tolerance of the Devil's Claw extract LI 174 in patients suffering from non-radicular back pain over a period of at least 6 months. A total of 130 patients were treated twice a day with tablets containing 480 mg LI 174. The treatment lasted for 8 weeks.

Initial experience with SPECT examinations using [123I]IBZM as a D2-dopamine receptor antagonist in Parkinson's disease.

[123I]IBZM is a new radioactive labelled ligand which has a high affinity and specificity to D2-dopamine receptors. The in vivo kinetics of [123I]IBZM were studied in patients with unilateral and bilateral accentuated idiopathic Parkinson's disease. The uptake in the basal ganglias and the imaging properties of this D2 receptor antagonist as a radiopharmaceutical for SPECT examinations had to be investigated.
