    C2 rotation and spinous process deviation in migraine: cause or effect or coincidence? (1991)

    Notizen: Summary Previous reports have shown an association between the side of C2 spinous process deviation or asymmetrical prominence, or vertebral rotation, and the side of the headache in unilateral migraine. However, this study has found that such C2 appearances were present as frequently in the controls as in the migraine patients, and that there was no association between the side of the anomaly and the lateralisation of the headache. The results were comparable for the different sub-groups of migraine.

    Notizen: Abstract Five extraction techniques were used to obtain quantitative measurements of monoterpenes from blue spruce and grand fir needles. Multivariate analysis of variance indicated that there was a significant difference in the amount of each monoterpene extracted by using different techniques. For both species, an 8-hr steam distillation of 10 g of material yielded the greatest amount of each monoterpene. This technique was also the most reproducible in that the coefficients of variation were lowest. A rapid steam distillation was relatively effective for grand fir, but not for blue spruce. A CO2 extraction was unreliable for both species.
