Using atomic absorption spectrometry Pb, Cd, Cu, Zn and Fe were measured in sweat and Pb, Cd, Cu and Zn, in blood. The subjects were 22 healthy males, aged between 23-44. Sweating was induced with an environmental room (1 hour at 46C dry bulb and 36C wet bulb). Sweat samples were obtained from the left arm by the armbag technique. The sweat volume was 23.3+7.3ml(n= 22). The concentrations, in ug/ml, of trace elements in sweat were : lead, 0.18+0.17(n=22); cadmium, 0.006+0.006(n=22); copper, 0.37+0.66(n=10); zinc, 0.63+0.5(n=10); and iron, 0.22+0.12(n=10). The concentrations, in ug/ml, of trace elements in blood were : lead, 0.28+0.15(n=20); cadmium, 0.005+0.007 (n=20); copper,0.69+0.22(n=20); and zinc,5.61+0.86(n=20). These results clearly showed the significance of sweating as a route of excretion of trace element.

To study the relationship between the bone mineral density measured by DEXA and QCT methods and to study the factors influencing on the value, bone mineral density in 208 patients with low back pain were measured by the two methods and compared statistically. Ages were varied between 17 to 79(Av. 46.7) years and male and female were 86 and 122. The results of this are as follows; 1. The values of DEXA and QCT showed statistically significant relationship(γ=0.58) as a whole. And bone mineral density in L2, L3 and L4 showed no difference in both groups. 2. Bone loss by aging(per year) in male and female was 0.99% and 1.06% by DEXA, 0,99% and 1.41% by QCT. 3. Body height and weight showed no significant influence of the value in two methods. 4. In body mass index over 27.5, the value measured by QCT was influenced to be diminished while that of DEXA was not influenced. 5. The value by QCT was influenced to be diminished by the increase of age especially over 50 years old in both sex. While the value by DEXA was influenced to be lowered than expected in female over 50 years old. It is concluded that the methods of measurement of bone mineral density have their limitation depend on the age, sex and mass index.

Osteoblastoma is a benign lesion somewhat similar to ostoid osteoma histologically but different from it clinically, roentgenologically and grossly. The autors have experienced a case of benign osteoblastoma of the neural arch of the Iumbar spine, and treated the case by total laminectomy and conflrmed with biopsy.

OBJECTIVE: We analyzed 200 cases of prenatal amniocentesis and compared them with other reported studies. Thus we propose the necessity of metanalysis for prenatal amniocentesis. METHOD: We analyzed 200 cases that have undergone amniocentesis at Masan Samsung hospital from January 1996 to December 1997. The results of our study was compared with other reported studies of amniocentesis by indication and maternal age. The proportion of age-class and indication are compared between previous study subjects and our 200 cases. RESULTS: Triple marker abnormality was the most common indication of amniocentesis(51%) and the most common age distribution was 25-29 years (43.5%). Chromosomal aberration was diagnosed in 20 cases (10%) of which the numerical aberration was 9 cases (4.5%) and the structural aberration was 11 cases (5.5%). 5 cases (2.5%) out of ll cases of the structural aberration were normal variant. There were 7 cases (trisomy 21) of autosomal aberration and 2 cases (Turner syndrome) of sex chromosome aberration. Arnong the structural aberration, there was only one reported case of 46, t(7:10) reciprocal translocation. There were no cases of fetal death except for a little self limited preterm labor. There were no neonatal complications. In the comparison of indication and maternal age with other studies, abnormal triple test was the most common indication of amniocentesis. The number of young pregnant women under 35 years old who underwent genetic amniocentesis was increased year by year. CONCLUSION: Triple maker screening test and genetic amniocentesis become popular method of antenatal diagnosis in Korea. Now, it is the proper time to establish standard indication of prenatal amniocentesis in this country by systemic and objective statistic examination. So we address the need for metanalysis in our country as comparing with other studies.

The Duodenal diverticulum is the rare cause of the common bile duct obstruction. We experienced a case of the diverticulum of the second portion of duodenum in a 59-year-old male, who complained recurrent attacks of right upper abdominal pain and fever since 16 months prior to admission. Duodenoscopic finding and UGI study revealed a typical duodenal diverticulum just side to the papilla of Vater. Diverticulectomy and cholecystectomy was performed and after than, he has been free front above mentioned symptoms. We reported a case of duodenal diverticulum which caused recurrent common bile duct obstruction.
