Every patient received three types of drugs: thioctic acid with cyanocobalamine, vincamine, and lutein. The drugs were given daily for 3-12 mo according to patient’s responses. Full field flash electroretinogram(ERG) and flash visual evoked potential(VEP) were done before treatment and at 1, 3, 6, and 12 mo sequentially. Patients were followed up for 12 mo.RESULTS: In the 2000 eyes, 1000 eyes had both moderate optic nerve and retinal function defects;and 840 eyes out of the 1000 improved with the medical treatment. Another 500 eyes out of the 2000 eyes had extinguished retinal function with normal optic nerve function and only 125 eyes of them improved. The 290 out of the 2000 eyes had severe defects in optic nerve with normal retinal function and 130 of them improved. Another 210 eyes have mild optic nerve and retinal function defects and 194 improved.CONCLUSION: The combination of vincamine, thioctic acid with cyanocobalamine, and lutein improved both retina and optic nerve functions mainly in mild and moderate defect than in severe cases.展开更多

Fast insulin and glucose stimulus insulin were investigated before and after 3 months taken treatment. The use of thioctic acid, 600 mg is a new effective pathogenetics therapy of polycystic ovary syndrome on influence of hyperinsulinemia, HOMA-IR index and ovary volume in female patients with polycystic ovary syndrome.展开更多

The ion permeation was evaluated by using relatively low excitation frequencies, 0.2 Hz to 1000 Hz, and quantified by an extra resistive component in the equivalent circuit (RSAM). The extent of ion permeation affected by the electrode potentials and the electrolyte concentration were investigated. The experimental results verified that RSAM decreased ~70% by interaction with copper ions and that RSAM increased ~2 - 3 times when the electrolyte concentration was decreased by 10 times. This analysis can be performed without addition of redox species.展开更多
