Objective To investigate the protective effects of prescription for nourishing liver- kidney (PNLK) on PC12 cell injyred by 1- methyl- 4- phenylpyridinium (MPP+ ).Methods The rabbit serum contained PNLK was preparing by the method of sero- pharmacology.PC12 cell was cloned from pheochromocytoma of adrenal medulla and the MPP+ injured models were induced by nerve growth factor.The effect of serum containing PNLK on PC12 cell from MPP+ injured models was assayed by morphological, MTT staining and LDH measurement.Results The equivalent dosage of the serum of PNLK possessed obvious protective effects on PC12 cell,increased the number of survival cells and relieved the injury significantly.Conclusion Serum of PNLK can counteract the injuryof PC12 cell induced by MPP+ and has protective effect on PC12 cell in vitro.

BACKGROUND: It is indicated in a large amount of basic researches that compound danshen di wan has a certain action on removing carotid atherosclerotic plaques (CAP), but there is lack of large sample data in randomized, controlled, multi-central clinical experiment.OBJECTIVE: To observe the removing action of compound danshen di wan on CAP, compared with aspirin.DESIGN: Multi-central, randomized controlled experiment was designed.SETTING: Research Center of Traditional Chinese Medicine and Ultrasonic Department of Xinjing Hospital, Fourth Military Medical University of Chinese PLA; Department of Traditional Chinese Medicine of Second Clinical Hospital, Xi' an Jiaotong University and Department of Cardiac Internal Medicine of Xi' an Hospital of Traditional Chinese Medicine.PARTICIPANTS: Totally 162 cases were selected from the clinic of Research Center of Traditional Chinese Medicine, Fourth Military Medical University of Chinese PLA; Department of Traditional Chinese Medicine, Second Clinical Hospital, Xi' an Jiaotong University and Department of Cardiac Internal Medicine of Xi' an Hospital of Traditional Chinese Medicine from 2002 to 2004, aged varied from 40 to 80 years, the thickness of carotid internal media ≥ 1.2 mm. They were randomized into two groups, named danshen di wan group of 89 cases(cases of soft plaque and hard plaque were 49 and 40 respectively) and aspirin group of 73 cases(cases of soft plaque and hard plaque were 42 and 31 respectively).METHODS: In danshen di wan group: compound danshen di wan was administrated orally(10 pills/time, 3 times/day), in aspirin group, enteric soluble aspirin table was administrated orally(75 mg/time, once a day),continuously for 6 months. The alternations of thickness of carotid internal media were determined with ultrasonic B of high resolving power before and after treatment.MAIN OUTCOME MEASURES: Changes in thickness of carotid internal media before and after treatment.RESULTS: By practical measuring analysis, 143 cases accomplished nation of thickness of carotid internal media in the patients with soft plaque:In danshen di wan group, the thickness was remarkably decreased after treatment[ (2. 12 ± 0. 34), (2.44± 0.40) mm, t = 4. 267, P ＜ 0.01 ] . In aspirin group, it was also reduced relatively after treatment[ (2.25 ± 0. 3),of carotid internal media in the patients with hard plaque: The changes were not significant no matter in danshen di wan group or aspirin group in the comparison before and after treatment[in danshen di wan group: (2.46 ±0.42),(2.34 ± 0. 40) mm; in aspirin group: (2.42 ± 0. 44), (2. 36 ± 0. 38) mm,P＞ 0.05].CONCLUSION: Compound danshen di wan acts on removing soft atherosclerotic plaque and its effect is similar to aspirin.

The main clinical symptoms of Parkinson's disease (PD) are resting tremor, muscle rigidity, bradykinesia, and so on. There is no effective treatment for PD yet, and dyskinesia symptoms affect the life qualities of PD patients. The therapy used for reinforcing kidney and activating blood circulation in treatment of PD can achieve good clinical effects.
