Yang Zhiping Wu Qingsheng Dong Shilin et al (Anhui Sanitation and Anti-epidemic Station, Hefei, 230061)  
Vitamin B1 Deficiency status of 63 peasants from 16 families in south mountain area, where peoples fed mainly on refined rice, was investigated. The results showed that 7 peasants suffered from Vitamin B1 Deficiency (11.11%). A measure result of Vitamin B1 ug/g creatinine in urine indicated that Vitamin B1 ug/g creatinine in experiment group was lower than that in control group. Vitamin B1 in refined rice and their deit was also low. Unreasonable diet pattern, unscientific rice processing and cooking method might account for the Vitamin B1 deficiency. Mean while, under the condition of high temperature and high intensity of labor in summer and autumn, people's requirement for Vitamin B1 and heat increased. Vitamin B1 lost with sweat. Thus, pathological changes in peripheral nerves and oedema in lower limbers occured due to Vitamin B1 deficiency.
