Effects of pramipexole on contraversive rotation and functional motor impairments in 1-methyl-4-phenyl1,2,3, 6-tetrahydropyridine-induced chronic hemiparkinsonian monkeys

Rotational and functional motor behavioral changes were studied in five MPTP lesioned chronic hemiparkinsonian Macaca nemestrina monkeys after i.m. pramipexole, a predominant D2 subfamily agonist. Pramipexole induced contraversive rotations in a dose-dependent manner with an optimal dose of 56 microg/kg for approximately 2 to 4 hr after injection. Three different rating scales were used to determine drug-induced functional improvement. They included a monkey parkinsonism rating scale, volitional responses to fruit presentations, and number of hand movements that appeared volitional. A dose of 56 microg/kg of pramipexole produced functional improvements on hand disability, and on a parkinsonian rating scale for monkeys in a dose-dependent manner from 32 to 100 microg/kg. These doses produced an increase in significant hand movements in the affected (contralateral) as well as in the normal (ipsilateral) hand to the side of the brain lesion compared with 5% dextrose in water vehicle control. With a dose of 100 microg/kg, the therapeutic effects of pramipexole on hand movements were less than with 56 microg/kg, due to side effects such as scratching.

PH值对化学沉积制备CdS薄膜性质的影响

实验研究了pH值对化学沉积制备CdS薄膜性质的影响。表明：在柠檬酸钠作为络合剂的体系中随着溶液中氨水浓度的提高CdS薄膜会发生相变，从立方相变为六方相，即当氨水浓度为0．31M时，得到立方相的CdS薄膜；而当氨水的浓度大于0．51M时，得到六方相的CdS薄膜。氨水浓度的提高也使得CdS薄膜的形貌有了很大的改善，且制备得到的CdS薄膜从富CA变为富S，但是薄膜仍是n型。氨水浓度对CdS薄膜的光学性质也有很大的影响，随着氨水浓度的提高所得到的CdS薄膜的禁带宽度增大。
