This paper is studied for statistical anaIysis of 1181 cascs of positive V.D.R.L test among 24414 cases who were visited for annual Physical examination and in or outpatients in the Han Gang Sung Shim Hospital during 5 years and 7 months from January 1972 to July 1977. Clinical survey was carried out with 182 syphilitic patients in the Department of Dermatology, Han Gang Sung Shim Hospital during 19 months from January l976 to July 1977. The results were as follows; 1. Positive rate for V.D.R.L test was 4.8%, and there were statistically significant differences in annual incidence(P<0.01). Biologic false positive rate for V.D.R.L test was 26. 7%, and there were statistically aignificant differences in annual incidence(P<0.01). 2. Departmental analysis such as Dermatology, Urology, Physical Examination and others including Obstetrics and Gynecology, Internal Medicine, Pediatrics etc. were carried out, the results showed that there were statistically significant departmental differences in V.D.R.L positive rate, but no in biologic false positive rate. 3. Biologic false positive rate was high inversely proportional to dilution titer, and that was a statistically significant difference(P<0.01). 4. 182 had syphilis, of whom 106(58. 2%) were latent syphilis and 74(40. 7%) were primary and secondary syphilis. 5. 119(65. 4%) among 182 syphilitic patients were male, most of patients(87.8%) occured in age from 21 to 40 years in the both sex. But there no statistically significant differences in age distribution between males and females. 6. The most predilection site of chancre was coronary sulcus(54.5%). 7. The lesions of secondary syphilis were composed of 18 cases(25%) of condyloma latum, 17 cases(23. 6%) of roseolar syphilid, 17 cases of papulo-squamous syphilid, 13 cases of alopecia syphilitica, 1 case of pustular syphilid, and 6 cases of others. 8. Married patients were nearly two times than single. In women, married. patients were much more(80. 3%) than single, and there were statistically significatnt differences(P<0.01). 9. There were no significant differences in S.T.S positive rate of spouse between infectious and latent syphilis. 10. Occupation distribution of male sexual partners were composed of 35 cases(29. 4%) of waitress, 28 cases(23. 5%) of call-girl, 20 cases(16. 8%) of office-girl, 17 cases of housewife, 12 cases of out of work, 7 cases of student. 1I. For patients with primary, secondary, and latent syphilis, treatment consiste of benzathine penicillin 2. 4 million units intramuscularly on the first visit and repeated three penicillin preparations at 7 days intervals in most of patients.

Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1 mm in thickness, were prepared from extracted third molars free from decay and wear, and a spilt chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with Astringedentr , Altract and Epri-dent , were compared and analyzed. The following conclusion were drawn : 1. Hydraulic conductance values which wee measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. on SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. on the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.

In the operation room of S.N.U.H., 10 patients were transfused with A,C.D. stored blood after warming to 36 degrees C by using a blood warmer. Observed changes of Na+, Cl-, K+ and. Ca++ were as follows. 1) Before warming, the electrolytes of A.C.D. stored blood were Na+ 148. 2 mEq/1, Cl-; 117. 0 mEq/1 and K+; 8. 4 mEq/l. After warming to 36C, these were significantly reduced(P <0. 05) and became 144. 6mEq/1, 112. 4mEg/1 and 68. 13mEq/1 respectively. 2) There was a tendency to increasing of K+ cencentration in proportion to storage duration. 3) In the case of calcium, pre-warmed concentration of calcium was 4. 09 mEq/1 and there was no significant change after warming(P>0.05).

This study was carried out in order to find out the valuable measure to kill the parasite eggs in night soil. The fresh eggs of Ascaris put into human stool were irradiated with Cobalt 60 of 200,000 to 1,000,000 rad and cultured in test tubes at 25-30 C, washing with 2 percent formalin solution every 24 hours. The continuous development of those eggs were observed under microscope and the proprotions of developed eggs were compared with those of control groups. The major result can be summarized as follows: In general, The eggs in stool developed poorly than the eggs in saline. If the eggs were irradiated with the larger dose of Cobalt 60, the proportion of developed eggs were reduced subsequently. The eggs irradiated with the dose of 1,000,000 rad in saline developed in the proportion of 15.5 percent, whereas irradiated with 200,000 rad 94 percent developed in 4 weeks. The 44.5 percent of eggs in stool irradiated with 200,000 rad developed after 4 weeks, 30.5 percent with 300,000 rad, 25 percent with 500,000 rad and 3.5 percent with 1,000,000 rad respectively. The effective minimum dose of Cobalt 60 irradiation to kill the Ascaris eggs in stool was estimated 1,000,000 rad. Further examination will be required to observe the infectivity of irradiated Ascaris eggs to animals and to evaluate the effect from the standpoint of sanitary engineerings.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.
