[Determination of water soluble silicon from herbal drugs]

This article has set up a method for silicon determination by ammonium molybdate-ferrous sulfate-sodium carbonate spectrophotometry. The method is simple, convenient, quick, effective and free of the influence of phosphate ion and reducing agents such as vitamin C and so on. By this method water soluble silicon has been determined in 38 herbal drugs.

[An APC composite analysis system for analyzing the cause of perinatal death]

As the cause of perinatal death is multi-factorial and complex, its analysis should be a composite one. The method stated here includes the following: The APC analysis system. A is autopsy, P is placental pathological examination and C is the clinical data. The analysis is based mainly on the diagnosis of autopsy, with the findings of placenta as a non-negligible component part of the autopsy. As for the clinical data, they are both as the start point of the autopsy and the final check for the conclusion drawn from the pathological examination. The analysis procedure of a complex case is given in detail for example. Strictly applying this system, the causes of perinatal death were clarified in 99.3% of 137 cases, and in 98.6% (66/67) of stillbirths. The underlying factors of primary perinatal death are usually neglected, which could be found out as well with this system. For example, the underlying factors inducing intrauterine anoxia of 92.3% of cases (36/39) were determined by using the APC system. The role played by the placental pathological examination in this analysis system is clearly shown and stressed, especially in the stillbirths. The quality of causal analysis of perinatal death is greatly improved by applying the APC analysis system.

Observations on the treatment of coronary heart disease by kuo guan qu yu ling

Based on the therory of promoting flow of qi and dispersing blood stasis, the KUO GUAN QU YU LING coronary--dilating and stagnation--dispersing) powder in capsules were prepared for the treatment of 60 cases of coronary heart disease. After a 30 day course of treatment, cardiac ischemia was improved in 64.7% and the symptom of angina pectoris was relieved in 61.7% of the patients. This drug also acted to reduce blood lipids and to improve left cardiac function. Pharmacological study indicated that this preparation improved the tolerance of cardiac muscle against anoxia and prevented ventricular fibrillation and cardiac damage from ischemia.
