作者研究米糠对含钙尿路结石和自发性高钙尿病人的排泄尿钙的作用。实验对象为进普通饮食的男女高尿钙病人(24小时尿>200mg),都是非卧床者并有尿路结石病史,都排除原发性甲状旁腺机能亢进,肾小管性酸中毒或其他能引起高钙血或高钙尿症的情况。进食两种米糠,一种为脱脂米糠(未加工的米糠提取掉米油),另一种为加工的米糠(脱脂米糠提取掉肌醇六磷酸钙镁)。
The authors investigated the effect of rice bran on urinary calcium excretion in calcified urolithiasis and spontaneous hypercalciuria. Subjects were male and female patients with hypercalciuria (24-hour urine> 200 mg) who were enrolled in a regular diet who were non-bed-bound and had a history of urolithiasis, with primary hyperparathyroidism, renal tubular acidosis or other Caused by hypercalcemia or hypercalciuria. Two types of rice bran are consumed, one is defatted rice bran (unprocessed rice bran is extracted from rice oil) and the other is processed rice bran (defatted rice bran is extracted from calcium phytate).
