Normal presence
1.Unsaturated alkynyl alcohols, such as dehydronerolidol, dehydrogeranyllinalool, and dehydroisophytol, were prepared by ethynylation of turpentine derivatives, namely terpenylacetones, e. g. geranylacetone, farnesylacetone, and phyton under normal pressure in presence of alkali metal hydroxide and organic solvents.
2.and 3 eye,with primary open-angle glaucoma with tritan defects. Results:There is a kink in the curye of log background light intensity versus log stimulating light intensity of l2 normal persons, and the thresholds of eyes with tritan defects fall about 10 dB,Normal eyes demonstrate the presence of triansient tritanopia after examination,Conclusion:The yellow background luminance of more than 200 asb(64 cd/m2)can isolate the blue-cone pathway.
3.Method Quantitative electromyography was performed in groups of lower motor neurons in 60 ALS patients with different initiative symptoms of onset, of defferent clinical stages and 55 matched normal control, to measure MUPs parameters, the presence of spontaneous activity was detected and the recruitment order was measured.
