This study was performed to investigate the retrievability of the cementation type implant abutments. The cements used in this study were Cavitec, Tembond and Zine Phosphate Cement. The types of surface conditioning were no treatment, 50 microne sandblasting, 250 microne sandblasting, fine diamond finishing point and coarse diamond point. The retention of cast crown was measured with Instron University Testing Machine(Instron Engineering Co., U.S.A.) The results were as follows: 1. The Maximium retention was obtained by the group of Z.P.C. cementation and Coarse diamond point surface conditioning. 2. Z.P.C. shows maximum retention, and reduced in orders Tembond, Cavitec, No cement. 3. The value of retention of surface condition was highest in coarse diamond point, lowest in no tretment. 4. The similar results were obtained between fine diamond point and 50 microne sandblasting, coarse diamond point and 250 microne sandblasting. 5. The were no direct corelation between mechanical retetnion and cementation retention.

Recent development of dignostic tools such as video-endoscopy, chromoscopy, magnifying endoscopy, and endoscopic ultrasonography has made it possible to do the accurate staging of colorectal cancer. Dysplasia confined to mucosa or upper one-third of submucosa of rectal wall can be treated with mucosal resection or local resection for cure. The involvement of perirectal lymph node by cancers can be confirmed by endoscopic ultrasonography-guided fine needle aspiration cytology (EUS-FNA). Positron emission tomography is useful for the detection of recurrent and metastatic tumor after surgical resection. Colonoscopy is cost-effective for the screening of cancer, however, But the virtual colonoscopy with MR or CT can play the role of colonoscopy without risk. Stool DNA test is a promising tool. In addition to traditional diagnostic tools such as colonoscopy, CT and pathology, emerging knowledge from molecular biology of cancer gives information on predicts the prognosis of colorectal cancer patients.

A case of familiar benign chronic pemphigus is reported. A 41 years old housewife has recurrent history of developing grouped vesicular eruptions with erythematous erosion on the intertrigenous area since 29 years of her age. The lesions were used to aggrevated in summer and improved in autumn. Familiar history revealed same disease of her grand mother, father, 44 year old elder sister and 39 year old younger sister. All of whom had similar clinical signs and symptoms. Routine physical and laboratoryfindings were within normal limits. The histopathological findings, from vesicular eruption of the lateral aspect of neck, showed multilocular suprabasal clefts with acantholsis, villi formation and hyperkeratosis. The lesions were-improved hy the local application of corticosteroidoid ointment only.

A case of hereditary anhidrotic ectodermal dysplasia associated with atopic dermatitis in 16 month old male is reported. He has been suffered from multiple symptoms of anhidrosis, hypotrichosis, anodontia and atopic dermatitis. The skin showed pale, shiny, thin and dry and hairless on whole body except in the scalp. Without sweat gland and flattening of epidermis on skin biopey is compatible with an hereditary anhidrotic ectodermal dysplasia.

The 16 out of 19 cases with combined oral administration oral of Descrespet and Tetracycline hydrochloride were considerably more effective in treatment of severe acne than Tetracycline hydrochloride alone or placebo in this study. 10 cases of atopic dermatitis and 6 severe acne with side effect for tetracycline hydrochlorid, such as aMominal discomfortness, also treated with Descresapt: 7 cases of atopic dermatitis and 4 acne cleared definitely faster than in patient not given Descresept Conclusively, it is cnosidered that the Descresept is effective in the tretment of severe acne and atopic dermatitis.

In order to avoid contamination attributed to Vanbreuseghem hair haiting technique in the laboratory, the author contrived the following modified method. After adding 100ml of antibiotics solution (mixture of 500mg of Cyclohexamide, 20, 000u of Penicillin and 40mg of Streptomycin in 1,000ml of distilled water) in PVC phial containing 100gm of soil, it was gently agitated for an hour and lefted to be settled for 12 hours. The suspended solution obtained and a batch of horse hair were randomly distributed on a Petri dishfitted with blue cloths, then cultured at 24C'. The overall results obtained from this modified method were not as satisfying as that of the Vanbreuseghem method but a few advantages such as simplicity of the procedure and significantly lower laboratory contamination implicated its practicality. Furthermore, this method was also found to be useful in the first isolation of infected animal hairs, hair perforation tests and as a substitution for artificial media. For the cross mating, a patch of blue cloths was laid on top cf moist sterilized soil evenly spreaded on a Petri dish. Then hair-baiting procedure was performed and good results were obtained.

The R-R interval analyzer was developed to measure the autonomic nervous system function using microcomputer. The system based on 8 bit microcomputer including bandpass filter, R-wave detector and clock generator in order to obtain the mean value, standard deviation, total time, CV value, maximum value and minimum value in the specific view point of R-R interval variation. The pattern of R-R interval change after resting, voluntary standing and deep breathing can be analyzed in normal subjects and diabetics with autonomic nervous dysfunction. The amplitude of the R-R interval variation showed sensitive pattern for normal subjects at resting, standing and deep breathing. On the contrary, the periodicities of amplitude for abnormal subjects with autonomic nervous dysfunction showed dull pattern. It was suggested that R-R interval analyzer is a good detection method for dysfunction of autonomic nervous system.

Colorecal cancer undergo relatively long preneoplastic processes before being invasive. Fecal occult blood test (FOBT) has been a useful tool to detect the advanced colorectal cancers with cost-effectiveness. However, the patient’s compliance to FOBT was poor because of low sensitivity and annual sampling. The sigmoidoscopy and colonoscopy have the ten-year preventive effect for the advanced cancer. Recently the DNA stool test for detection of mutations has showed excellent sensitivity and specificity. It has several adventages such as collection of samples and automated analysis. Virtual colonoscopy, especially CT colonograpy, can be a viable option for the colorecal cancer screening. In November 2001, the Korean Society of Coloproctology (KSCP) and the Natinal Cancer Center (NCC) developed the guidelines on screening and surveillance for early detection of colorectal cancers in Korea. Average-risk men and women should start colonoscopic examination with a 10-year interval at the age of 50. Individuals with increased risk such as those with a family or personal history of colorectal cancer or colorectal adenomas, or family history of familial adenomatous polyposis, hereditary non-polyposis colorectal cancer should consult their surveillance to the specialty-physicians. The ideal screening tools may change by age.
