Thirty-three patients with chronic auricular fibrillation were treated with digitalis and quinidine and in addition were given Dicumarol® to reduce the risk of embolism. In 21 of the patients the fibrillation was caused by rheumatic heart disease, and in 12 by arteriosclerosis or hypertension. Normal sinus rhythm was restored in 55 per cent of the 33 patients, in 67 per cent of those with arteriosclerosis or hypertension, and in 45 per cent of those with rheumatic heart disease. Embolism did not occur. 相似文献

The most generally accepted theory as to the cause of dental caries is that certain bacteria in the mouth, in the presence of fermentable sugars, cause the formation of acids which in turn decalcify teeth. Physicians may help reduce the incidence of caries by recommending elimination of refined sugars from the diet, or at least control of the amount consumed.Cleaning the teeth with a well designed tooth brush after each meal will to a certain extent mechanically remove the fermentable sugar and debris from the teeth. One step further in oral hygiene that may be beneficial is to use a dentifrice with 5 per cent dibasic ammonium phosphate and 3 per cent urea to reduce the formation of acid.Anything that will increase salivation will aid in buffering any acids that may be present.A 2 per cent solution of sodium fluoride applied to the thoroughly dried “intact” enamel surface may prevent caries.Sodium fluoride added to drinking water to a concentration of 1 part per million is utilized by the body in formation of an enamel that is particularly resistant to caries. 相似文献
