A survey on the prevalence of intestinal parasites was performed during the period from April to June of 1969, to evaluate the present status of parasitic infections in ROK Army soldiers. Stool specimens of 1,0l2 soldiers were collected from a camp located in Won-Ju area, and examined by the method of formalin-ether sedimentation technique. For protozoan cysts, examined slide was stained with Lugol's iodine solution and for eggs of Enterobius, the Graham's scotch cellulose tape anal swab technique was applied. The results obtained in this survey were as follows: Of the 1,012 soldiers examined, 95.0 percent were found infected by one or more intestinal parasites and 28.7 percent were found positive for protozoan cysts. The positive rates of each parasites were; A. lumbricoides 61.0 percent, T. trichiurus 73.4 percent, hookworm 17.5 percent, T. orientalis 9.5 percent, E. vermicularis 0.1 percent (from stool specimen), C. sinensis 8.8 percent, M. yokogawai 1.1 percent, Taenia sp. 1.0 percent (from stool), H. nana 0.3 percent and E. histolytica 7.4 percent. E. coli 12.6 percent, E. nana 5.9 percent, I. buetchlii 0.7 pecent, G. lamblia 6.1 percent, and C. mesnili 0.8 percent. From the anal swabs, eggs of Enterobius were recovered in 2.6 percent, and eggs of Taenia sp. showed positive rate of 1.5 percent.

We report one case of hair follicle nevus, benign highly differentiating appendageal skin tumor of hair follicle. It arises from pluripotential cells that have formed during life. This patient is a 40-year-old woman who had a localized brownish plaque on the leht cheek for three years. Histologic study revealed many small but mostly mature hair follicles consistent with hair follicle nevus.A Case of Cutaneous Periarteritis Nodosa

A 25-year-old female was seen because of rnultiple, asymptornatic papular eruptions on the vulvar area since 1 year ago. She had been suffered from palmar hyperhidrosis for 3 years. A skin biopsy specimen from the vulval lesion revealed characteristic findings of syringoma.

A 72 years old man had an 1 x 1cm sized, solitary glomus tumor on the right knee joint and had suffered from sharp, episodic pain and tenderness, radiating to the right thigh and the buttock for about 20 years. Simple surgical excision was performed for removal of the tumor mass and the subjective symtoms. There is no recurrence until now.

Although we made a comparision of fingertip dermatoglyphic patterns between R7 patients with atopic dermatitis(Femals: 54, Male: 35) and 73 their families without atopic dermatitis, no significant results were obtained. So, we compared secondly our results of 2 groups with those of two thousand nonatopic, normal Koreans, as control. Results are as follows: ] In comparison with control, a significant increase in the ulnar loop pattern was detected in families(p<0, ()5), not atopic dermatitis. p. No significant differ ence between right hands and left hands in all three g f OUpS. In atopic dermatitis and control groups, 1 st and 4 th digits showed mostly whorl pattern, and 3 rd and 5 th digits had more ulnar loop pattern than others. Rut families had mostly ulnar loop pattern at all digits except 4 th digit, wl..orl pattern. 4. Each of atopic dermatitis, family and control group had 13, 79% (whor1: 8. 05% ulnar loop: 5 75%), 15. 49p; (whorl: 4. 23%, ulnar loop: 11. 27%), 15. 78%(whorl: 8, 52% ulnar loop: 7. 1 %, arch: 0. 05%), of same dermatoglyphic pattern on all ten digits. Especially, ulnar loop pattern in fanilies was detected significantly higher than other two groups(p<0. 05). Average incidences of bilateral symmetry of pattern type between right and left digits were 78.57%, 74. 67% and 78.74% respectively in atopic dermatitis, family and control group.

BACKGROUND: The appearance of multiple-drug-resistant Mycobacterium tuberculosis strains has been seriously compromising successful control of tuberculosis. Rifampin-resistance, caused by mutations in the rpoB gene, can be indicative of multiple-drug-resistance, and its detection is of great importance. The present study aimed to develop an oligonucleotide chip for accurate and convenient screening of drug-resistance. METHODS: In order to detect point mutations in the rpoB gene, an oligonucleotide chip was prepared by immobilizing specific probe DNA to a microscopic slide glass by a chemical reaction. The probe DNA that was selected from the 81 bp core region of the rpoB gene was designed to have mutation sites at the center. A total of 17 mutant probes related to rifampin-resistance including 8 rifabutin-sensitive mutant probes were used in this study. For accurate determination, wild type probes were prepared for each mutation position with an equal length, which enabled a direct comparison of the hybridization intensities between the mutant and wild type. RESULTS: Mycobacterial genomic DNA from clinical samples was tested with the oligonucleotide chip and the results were compared with those of the drug-susceptibility test in addition to sequencing and INNO-LiPA Rif. TB kit test in some cases. Out of 15 samples, the oligonucleotide chip results of 13 samples showed good agreement with the rifabutin-sensitivity results. The two samples with conflicting result also showed a discrepancy between the other tests, suggesting such possibilities as existence of mixed strains and difference in drug-sensitivity. Further verification of these samples in addition to more case studies are required before the final evaluation of the oligonucleotide chip can be made. CONCLUSION: An oligonucleotide chip was developed for the detection of rpoB gene mutations related to drug-susceptibility. The results to date show the potential for using the oligonucleotide chip for accurate and convenient screening of drug-resistance to provide useful information in antituberculosis drug therapy.

We experienced with 3 cases of penile fractures for recent 2 years, one occurred during masturbation and the others occurred during coitus(one case was associated with urethral injury). While the former was treated with conservative management, the latters were treated with surgical intervention that was immediate removal of hematoma and primary closure of ruptured corpus cavernosum. Penile deformity end decrease in rigidity occurred in conservatively treated case. However, two cases of immediate surgical treatment had a excellent result without complication. Even though we describe only 3 cases and could not compare the degree of injury. our short experiences suggest that immediate surgical intervention is better than conservative management in initial treatment of penile fracture.

STATEMENT OF PROBLEM: The increased awareness of esthetics in dentistry has brought the esthetic consideration in prosthetic restorations. Dental ceramics offer better esthetics for use of prosthetic restorations. Unfortunately, dental ceramic materials are not always the most suitable candidate materials since their inherently brittle nature. In recent years, basic research in ceramic science has led to the recognition of several approaches to strengthen and to enhance esthetics of ceramics. Several all ceramic systems use ceramic core and porcelain build up structures. Ceramic cores influence to strength of all ceramic crowns. So the strength of ceramic cores is important to all ceramic crowns. PURPOSE: The purpose of this study is to estimate the flexural strength of ceramic cores in some all ceramic systems. Material and method : A biaxial flexure test was conducted on three groups(Cergo, Empress 2, In-Ceram). Each group consisted of 30 discs of nearly identical dimension with a 0.5mm, 1.0mm, 1.5mm thickness and 12mm in diameter. The fracture load was recorded by Instron. Analysis of variance(ANOVA) and Tukey's tests were performed using SAS statistical software. RESULTS: 1.5mm thickenss of specimens were significantly stronger than 0.5mm and 1.0mm thickness of specimens in Cergo and In-Ceram. But each sepecimen group of Empress 2 was no significantly strength by thickness. In order of In-Ceram, Empress 2 and Cergo has significantly stronger strength in the same thickness. CONCLUSION: In-Ceram is the strongest ceramic material in 3 materials. All the materials can be used according to the required characters.
