Recent reports suggest that the responses of the detrusor muscle to the hypogastric nerve stimulation and some autonomic drugs may not be identical among various species. In this study, the responses of the isolated detrusor muscle strips of the Amyda Japonica and the rabbit to catecholamines were compared, and the type of the adrenergic-receptors was investigated. The results obtained were as follows : 1. Catecholamines (norepinephrine and epinephrine) evoked only contraction in the isolated detrusor muscle of the Amyda Japonica and relaxation in the preparation of the rabbit. 2. The contraction-response in the Amyda Japonica was blocked in the presence of regitine, an adrenergic alpha-receptor blocking agent. 3. The relaxation-response in the rabbit was abolished by pre-treatment with propranolol, an adrenergic beta-receptor blocking agent. 4. Acetylcholine elicited contraction in both of the isolated detrusor muscle strips of the Amyda japonica and the rabbit, and the response was completely blocked in the presence of atropine. 5. The results described above suggest that catecholamines exert excitatory effect on the detrusor muscle of the Amyda japonica as it contains adrenergic alpha-receptors and inhibitory effect on the same preparation of the rabbit as it contains the adrenergic beta-receptors. Key Word : amyda japonica,alpha receptor, beta receptor.

BACKGROUND: Morphologic characteristics of the human embryonic and fetal periderm according to body region are not very clearly defined. OBJECTIVE: We have tried to Clarify the sequential development of periderm regionally. METHOD: Skin samples were obtained from 12 human embryos and fetuses ranging from 4 to 23 estimated gestational ages(EGA) and divided regionally into scalp, face, back. abdomen, thigh and sale. Specimens were observed by scainning with an electron microscope. RESULTS: Human embryonic end fetal periderm show distinct morphologic changes as follows along its own sequence of development flattened surface, elevated surface, fiormation of incomplete bleb. single bleb stage, multiple-complex bleb stage, formation of regressinjg bieb. Then towards the end of the second trimester, most of thieperidermal cells are completely regressed. Regional variation in peridermal development is not evide!nt during the embryonic period, but earlier development is apparent in the sole, face and scalp especially in the sole compared to other areas during the late first snd second trimester after EGA 9 weeks. CONCLUSION: The periderm, which can be seen only in embryonic and fetal epidermis, shows distinct sequential developmental changeis with regional variation.

One of the most difficult problems confronting the orthopedic surgeon today is what to do when faced with a large defect in a peripheral nerve. Recent advances in engineering and neurophysiology have improved our technical ability to understand the consequences of severing a nerve. We have treated a large traumatic ulnar nerve defect with microsurgical nerve graft technique. In a follow-up study of twehre monthes post surgery, the results were satisfactory.

Wegener's granulomatosis is a systemic necrotizing vasculitis of unknown cause. The disease is characterized by the involvement of the upper airway, the lung, and the kidney. Skin lesions are frequent and the most common lesion is purpura distributed on the limbs and trunk. A 34-year-old female showed recurrent purpuric macules on the both lower extremities and buttocks. The patient. showed nasal septal perforation with saddle nose deformity and C-ANCA positivity. Histopathologic findings of purpuric lesion revealed the features of necrotizing vasculitis. The histologic specimen from the nasal cavity showed chronic inflammation with granuloma formation and kidney showed focal necrotizing glomerulonephritis. Therefore, we treated the patient with prednisolone and cyclophosphamide having diagnosed Wegener's granulomatosis.

BACKGROUND: In order to investigate the efficacy and safety of cilazapril, a recently developed angiotensin converting enzyme inhibitor, a clinical study was performed in the patients with mild to moderate essential hypertension. METHODS: The study subject consisted of 31 patients with diastolic blood pressure of 95mmHg~115mmHg (mean age : 56.0+/-8.1 years, 16 males and 15 females). Cilazapril was administered orally in a daily dose of 2.5mg~5.0mg Q.D. for 8 weeks. During cilazapril medication, anti-hypertensive efficacy, side effects and laboratory changes were monitored. RESULTS: Cilazapril decreased blood pressure from baseline value of 162.2+/-4.7/98.4+/-2.8mmHg to 144.6+/-10.0/89.7+/-5.7mmHg after 4weeks of medication (p<0.05) and 138.2+/-4.5/87.8+/-4.0mmHg after 8 weeks of medication (p<0.05). Heart rate change was not significant (72.3+/-4.7/min vs 71.7+/-3.6/min). Body weight change was not significant (66.6+/-9.8 Kg vs 66.8+/-9.9 Kg). There were no significant change in blood chemistry and hematologic examination except mild elevation of alanine transaminase and serum creatinine values but these date were within normal ranges. The side effects were dry cough (4 case, 12.9%), headache (2 case, 6.4%), indigestion (1 case, 3.2%) and dry mouth (1 case, 3.2%). One patient dropped out due to severe dry cough but others were mostly mild in nature. CONCLUSIONS: Cliazapril 2.5mg~5.0mg once daily regimen was effective and well tolerated in patients with mild to moderate essential hypertension.
