Anti-rat lymphocyte rabbit serum was prepared with lymphoid tissue of rat spleen. Prednisolone, Imuran and this antiserum were used to prolong the survival of full-thickness sliin homograft in albino rats. The results were as follows. l. Administratio of tle anti-rat lymphocyte rabbit serum in a dose of 0. 3cc for 2 days before grafting and 0. 3cc every 3 days until rejection resulted in prolongation of the, urvival of the grafts. (Mean, 15.3 days) 2. Administration of preInisolone to the recipients in a dose of 2mg/kg/day from 7 days Iielore grafting to the time of rejection resulted in prolongation of survival of the, rafts. (Mean, 8.4 days) 3. Adminitration of Imuran to the reciipients in a dose of 5mg/kg/day from 7 day defore gvafting to the time cif rejection resulted in prolongation of the survival of ther afts. (Mean,14.6 days)

BACKGROUND: It has been shown that L-type calcium channel blockers increase the muscle relaxation effects of non-depolarizing neuromuscular blocking agents whereas the potentiated neuromuscular blocking effects by L-type calcium channel blocker are resistant to reversal by neostigmine. The aims of this study were 1) to see whether the pretreatment of L-type calcium channel blocker, such as verapamil, aggravates the pipecuronium-induced muscle relaxation, 2) if so, to see whether these effects are reversed by anticholinesterase, such as neostigmine and edrophonium or potassium channel blocker, such as 4-aminopyridine. METHODS: The rat-phrenic nerve-hemidiaphragms (n=60) were prepared. Twenty microgram of pipecuronium was administered to all organ bath. All samples were divided into two groups according to the administration of 10uM of verapamil i.e. verapamil pretreated, non-pretreated group. The amounts of administered pipecuronium were gradually increased by 4ug until the force of twitch decreased to 10% of control value in both groups. Each group was subdivided into three groups according to the administration of 0.75 M of neostigmine, 12.4 uM of edrophonium or 40uM of 4-aminopyridine. RESULTS: The dose of pipecuronium required for the decrease of contractile force to 10% of control value was less in verapamil pretreated group than in non-pretreated group. And, the decrease of contractile force in both groups was more effectively reversed by 4-aminopyridine than neostigmine and edrophonium. CONCLUSIONS: Verapamil potentiates the pipecuronium-induced neuromuscular blockade and 4-aminopyridine is more effective to reverse verapamil pretreated, pipecuronium induced neuromuscular blockade.

Post-caval or retrocaval ureter is a congenital anomaly of the vascular system. This anomaly almost. always involve the rt. ureter and occurs more frequently in male We have reported a 36 years male of rt. postcaval ureter that was resulted marked hydronephrosis due to compression of rt. ureter by vena cava. Three months after the operation, excretory urogram showed previous caliectasis and pyelectasis were moderately reduced and previous dislocated ureteral course was corrected.

In spite of the progress in techniques and materials of the prosthodontic rehabilitation of patients with complete edentulous arches, prosthodontists still face patients' complaints about dissatisfaction and discomfort from their dentures. In the past several decades, prosthodontists tried to find the factors that influence the patient's satisfaction with dentures. However the results are contraversial especially with the psychological factor. In this study using patient denture satisfaction questionnaire' and Hopkins Symptom Checklist, we tried to find the correlation between the patient's denture satisfaction and the patient's psychological aspects. 23 complete edentulous patients who have visited the Department of Prosthodontics, Yonsei University Dental Hospital from September 1998 to June 1999 for complete denture treatment were asked to complete the questionnaires 4 to 6 weeks after the upper and lower complete delivery. After the measurement of validity of the questionnaires, correlations between the patient's general satisfaction with their new upper and lower complete dentures and the other satisfaction questions including the satisfactions with esthetics, retention, mastication, speech, comfort and other peoples's opinion and between the patient's general satisfaction with their new upper and lower complete dentures and the 5 symptoms of Hopkins Symptoms Checklist including somatic, obsessivecompulsive, interpersonal sensitivity, depression and anxiety were analyzed. Among the several satisfaction questionnaire items, comfort with the lower denture showed highest relation to the patient's general satisfaction with dentures. However, only the anxiety scale of Hopkins Symptom Checklist among the other symptom scales was related to the patient's general satisfaction with dentures. The two questionaires used in this study turned out to be valid means of analyzing patient's denture satisfaction and psychological status before and after the complete denture treatment.

A case of xeroderma pigmentosum complicated with squamous cell carcinoma is presented. A 15 year old male has had a history of a single walnut-sized tumorous growth of 6 months duration on tip of his nose and multiple light to dark brown pigmented macules on face, ears, neck, upper chest, extensor surface of both foreams and dorsal hands of about 14 years duration, recognizable photosensitivity of the cutaneous lesions and photophobia and lacrimation since early childhood. Xeroderma pigrnentosum was suspected under clinical background. Biopsy was performed on the facial pigmented lesions and on the tumorous mass on the nose, which revealed xeroderma pigmentosum and squamous cell carcinoma, respectively. The tumor was excised totally under local 2% procaine anesthesia, resulting in healing with scar formation and no recurrence was observed during 6 month's follow up. Dermabrasion of the entire face was done, with complete removal of the xerodermic skin lesions, but they all recurred after about 1 month.

Inflammatory linear verrueous epidermal nevus (ILVEN) first mentioned by Unna in 1896 is a rare variant of epidermal nevus characterized clinically by early onset in childhood, moderate to marked pruritus and persistent clinical course and histopathologically by predominant features of a chronic dermatitis or psoriasis. We present tbe first recorded case of a typical ILVEN developed in a 20-year-old Korean male, who has had an intensely pruritic linear verrucous patch, involving the entire length of the posterior aspeet of right upper extremity, volar aspect of right thumb and nails of ind.ex and ring finger since 5 years. Microscopic examination of the skin, biopsy specimens from the lesion on the right elbow joint area and the palm showed hyperkeratosis witb focal parakeratosis, moderate to marked acanthosis and elongation of rete ridges and papilla with mild exocytosis and moderate perivascular lymphocytic infiltration. Literature were reviewed.
