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 understand the mode of transmission in clonorchiasis, a survey was made in Kim-hae Goon, South Kyong-sang Do (=Province). The mathematical analysis of the age prevalence was done on the egg positive rates. And another analysis for the comparison was also made to the cited data from two areas, North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do. Some catalytic models of H. Muench (1959) were applied to the observed age prevalence. Because the both parameters, such as force of infection(a) and loss of positivity(b) were considered to be constant for a long period in the surveyed area, the two stage catalytic model by Muench was chosen to the analysis. In the surveyed area, Kim-hae Goon where the egg positive rates were 56.2 percent and 61.2 percent (by Kim, 1974), the constant values of 'a' were found to be 0.051 and 0.089 respectively. In other words, the force of infection was 51, 89 per 1,000 susceptibles. The values of 'b' were found to be 0.006 and 0.005. This means that the rates of disappearance from egg positive cases to negative were 6 and 5 per annum per l,000 positive cases in above area. Therefore, the two catalytic curves were expressed by the following equations, y = 1.133 {e(-0.006t) - e(-0.051t)} and y = 1.047 {e(-0.005t) - e(-0.089t)} respectively. In the cases of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do where the egg positive rates of clonorchis shown as 27.7 percent and 15.2 percent by Shin (1964) and Kim (l974), the curves were expressed by y = 1.769 {e(-0.010t) - e(-0.034t)} and y = 2.857 {e(-0.020t) - e(-0.027t)} respectively. From the above mathematical analyses by age prevalence in clonorchiasis, it was considered that the mode of transmission of clonorchiasis in the surveyed area, Kim-hae Goon presented more rapid pattern than those of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do.

The nonstructural protein NSP4, encoded by gene 10 of rotavirus, has been shown to play a role in viral assembly and known to be an enterotoxin, causing diarrhea in mouse pups. NSP4 gene was cloned from CBNU-2 (virulent bovine rotavirus/diarrheic fecal sample) and CBNU-1 (cell-culture adapted bovine rotavirus/isolated from CBNU-2 and 75 times passaged on MA104 cells), respectively, by reverse transcriptase-polymerase chain reaction (RT-PCR) and sequenced and compared. The sequence data indicated that the NSP4 genes of bovine rotavirus (BRV) were 751 bases in length and encoded one open reading frame of 175 amino acids beginning at base 42 and terminating at base 570. Differences in nucleotide sequence between CBNU-2 and CBNU-1 were observed at 6 positions (base 274, 296, 391, 394, 396 and 579). NSP4 gene of BRV exhibited a high degree of nucleotide (90% and 94%) and amino acid sequence (91% and 94%) and amino acid sequence (91% and 97%) homology with those of SA11 and UK but a low degree of nucleotide (77% and 79%) and amino acids sequence (81% and 85%) homology with those of Wa and OSU.

Two cases of duodenal bezoars are presented. Both were within pseudodiverticula of the duodenal bulbs whichwere created by chronic active ulcer disease. It is felt that deformed duodenal bulb interfered with transit ofthe gastrointestinal content causing the formation of bezoar within pseudodiverticula.

Oncogenous or tumor-induced rickets is recognized as Vitamin D-resistant hypophosphatemic rickets that heals after excision of a coexisting tumor in either bone or soft tissue. Its pathogenesis is not clarified, but it has been suggested that the tumor elaborates a homoral substance inhibiting tubular reabsorption of phosphate or that the tumor inhibits the synthetic process of 1, 25-dihydroxcholecalciferol. We present two cases of vitamin D-resistant rickets, one associated with intrasseous well-differentiated osteosarcoma in the pelvis and the other associated with fibrosarcoma of distal femur. The case with low grade osteosarcoma showed immediate improvement of rickets after excision of the tumor, but the case with fibrosarcoma showed no improvement after amputation and was fatally terminated 5 months later due to lung metastasis.

Benign tumors and tumor like lesions in the foot are uncommon and those that are malignant are rare. Metastatic cancer of bone distal to the knee and elbow is unusual. By contrast, non-tumorous lisions that cause swelling, pretuberance, or deformity are common. Fifty two cases of tumors on foot were treated at our department from Jan. 1970 to Dec. 1991, we have treated fifty two cases of foot tumor and analysed their clinical characteristics. Bone tumors were more frequent than soft tissue tumors (2:1). Among soft tissue tumors benign tumors were frequent than malignant(1.4:1), and fibroma was the most frequent tumor(30%). Benign soft tissue tumors occured frequently at Edward and Michael's Zone 3(57%). Benign bone tumors has higher incidence than malignant(20:1). Osteochondroma was the most frequent tumor (48%). Predilection sites for osteochondroma and enchondroma of foot was distal phalanges and mitatarsal bone, respectively.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.
