Motor vehicles are the major source of environmental air pollution through the combustion of lead-containing gasolines. People who live in the areas with heavy traffic usually have the higher blood lead levels. This study was to investigate the lead level between the maternal blood and their infants cord blood. Immediatly after Placental delivary, the sampls of cord blood and maternal venous blood were obtained randomly from 14 infants whose mothers had spent their entire pregnancy in Seoul. Lead concentration was determined by the dithizone method. The results obtained were summarized as follows: 1. Hemoglobin, Hct and RBC were significantly higher in cord blood than in the maternal blood, by 36%, 54.9%, 36.9% respectively. 2. MCV in cord blood was higher than that in maternal blood by 13.8%. But MCH and MCHC were lower than those in maternal blood, by 9.7%, 3.3% respectively. The differences were statistically significant. 3. Lead concentration of cord blood $(23.93\;{\mu}g%)$ was higher than that in maternal blood $(21.93\;{\mu}%)$ by 9.1%.

기초대사 측정에 있어 Douglas-Scholander법과 Sanborn-Metabulator를 사용한 성적의 비교검토
김동준(Kim, Dong-Jun),김명희(Kim, Myung-Hee),정애순(Chung, Ae-Soon) 대한생리학회 1977 대한생리학회지 Vol.11 No.2
Two methods have been widely used for measuring basal metabolic rates (BMR), Douglas-Scholander (open circuit) and Sanborn-Metabulator (closed circuit ) methods. The latter has been used more by clinicians, since the Process is simple. But it is not as accurate as the Douglas-Scholander method. We measured the BMR of 938 healthy individuals who were selected at random, using a Douglas-Scholander method. The lowest value of the 6 measurments in three days was taken from each subject in the basal state. A single determination of BMR also was made with the Metabulator for 684 individuals. We applied both methods for 13 subjects among them who have same physical conditions. The results obtained were as follows: 1. The mean value of BMR with the Metabulator is significantly higher than Douglas-Scholander method by 9.2%. 2. The Metabulator can be used for measuring BMR, since the normal value is generally less than 15% of BMR. But one may considered that there is likely errors about 10% in Metabulator method.
