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.

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.

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 antihypertensive effect of verapamil, a calcium channel blocker, was studied in 12 cases of essential hypertension (mean age 49, range 24-64). After 6 weeks administration (80-160mg t.i.d.), the following results were obtained : 1) Before medication, average systolic and diastolic blood pressure was 176.3/108.6mmHg. After completion of therapy, blood presure fell significantly down to 154.8/94.2mmHg (p<0.01). 2) Heart rate decreased slightly from average 74.3 per minute prior to medication to 69.3 per minute at the end of study (p<0.01). 3) Side effects, among which constipation was most common, were mild and did not compel any patient to diacontinue therapy. In conclusion, verapamil seems to be a safe and effective first-line drug for hypertension along with diuretics or beta blockers.
