The case of a 56-year-old woman with a keratoacarithoma(KA) of the labial mucosa is herein reported, The tumor was excised and the pathological features were characteristic of a KA, This case is reported because the oral mucosa is such an unexpected location for solitary KA and the labial mucosa of this patient received chronic actinic damage, which suggested an etiological relationship. Follow-up examination of the patient after four months showed no recurrence.

The objective of this study was to establish a good methodology to isolate single smooth muscle cells that are alive and respond properly to pharmacological agents. Canine urinary bladders were employed as the source of single cells, and acetylcholine, atropine and imipramine were used as indicators of pharmacological responsiveness. Imipramine, an antidepressant drug exhibited the anticholinergic and calcium antagonizing properties on rat detrusor muscle. To establish a control value for a further experiment to elucidate the mechanism of action of imipramine on detrusor muscle, we measured the concentration-response of single cells to acetylcholine in the presesnce of imipramine by length of the cells and compared the result with the response in the presence of atropine. Tiny chops of smooth muscle taken from anesthetized canine urinary bladder were incubated in collagenase solution at 36℃ for 17-20 minutes. The collagenase solution included collagenase 1.2 mg/ml, soybean tryspin inhibitory 0.08 mg/ml, bovine serum albumin 2% in 10 ml Krebs-Henseleit buffer solution aerated with a consistent breeze of 95/5% O2/CO2 to maintain the pH at 7.4. After washing with plain K-H solution on 450 mesh, cells were dissociated from the digested tissue for 12-15 minutes. Cell suspension was transfered in 5 ml test tubes and acetylcholine was added for the final concentration to be 10⁻¹⁴~10⁻⁹M. To find the optimal time to fix the cells to determine the contractile responses, 1% acrolein was added 5, 10, 20, 30, 60 and 120 seconds after the administration of ACh. The length of cells fixed by acrolein were measured by microscaler vis CCTV camers on phaes-contrast microscope. The average length of 50 cells from a slide glass was taken as the value of a sample at the very concentration point. Single cells were isolated from canine detrusor. The length of untreated cells varied from 82 µm to 94 µm. The maximal response to actylcholine 10E-9M was accomplished within 5 seconds of exposure, and the shortening was 19±3%. Atropine reduced the contraction of the cells concentration-dependently. Lmipramine which exerts a cholinergic blocking action on some smooth muscles also reduced the contraction concentration-dependently and by a similar pattern as atropine. These findings document that imipramine may exerts a cholinergic blocking activity in the single smooth muscle cells isolated from canine urinary bladder.

In a previous communication, we described a relatively simpli. method for assaying quantities of sweat using the skin surface hydrometer. In order to evaluate the pharmacologic response of weat glands in psoriasis, vitiligo and loalized scleroderma, we measured the basal skin conductance and the quantity of sweat induced by intradermal injections of pilocarpine nitrate in the lesional and per ilesional skin. The results were as follows : 1. In psoriatic plaques, based skin surface hydration and the sweat response to pilocarpine was markedly reduced (p<0.05), but there were no significant differences in normal perilesional skin. 2. In generalized vitiligo, basal skin surface hydration and the sweat gland response was normal. In the case of the segmental type, there was a slightly decreased sweat response in the lesion but, not significant statistically. 3. In the morphea plaque, basal skin surface hydration and the sw.at response to pilocarpine was markedly reduced but was normal in perilesional skin. This study presents evidence of the functional changes in the development of sweat secretion and surface hydration in the lesions of psoriasis, morphec and segmental type of vitiligo. The demonstration of ahnormalities in the pharmacolopic response to pilocarpine induction led us to suggest the possibility that some degree of sweat gland involvement is induced by the pathogenetic mechanisms of these diseases.

Leiomyomatosis peritonealis disseminata is a rare benign condition characterised by the occurrence of multiple leimyomas scatterred throughout the peritoneal cavity, giving the clinical impression of a wide spread malignant tumor. The histopathology of leiomyomatosis peritonealis disseminata is that of a benign leiomyoma, probably originating from the multipotent subcoelomic mesenchymal cells. Three cases with malignant transformation were described among previous reported fifty cases. Many of the early reports described the disorder in premenopausal women, and now the histogenesis is considered to be a metaplastic change by abnormal tissue response to the relatively or absolutely elevated female sex hormone. We report a case of leiomyomatosis peritonealis disseminata, which was diagnosed by multiple scattered submucosal and subseroal leimyomas of stomach, small bowel and colon, combined with advanced gastric cancer in a 58 years old man, Multiple submucosal tumors of the stomach combined with advanced gastric cancer were demonstrated by fibergastroscopy, upper gastrointestinal barium study and abdominal ultrasonography. During radical subtotal gastrectomy multiple submucosal and subserosal tumors of stomach, and subserosal tumors of small bowel and colon were observed and these tumors were confirmed as leiomyoma without malignant potential.

We reported herein a case of median raphe cysts and canal of the scrotum. The 7-year-old patient had had the beaded cysts of 0.1 to 0.5cm in size slong a cord-like canal measuring about 8cm in the median raphe of the scrotum since the birth on. The cystic wall was unilocular and lined by pseudostratified columnar epitheliurn of one to four cells in thickness.

We report herein three cases of superficial migratory thrornbophlebitis, who were all male, aged 33(Case 1), 49(Case 2), and 41(Case 3), respectively. Common to all three cases were the lesions which were multiple tender superfieial erythematous nodules, about 0.5 to 1.5cm in diameter, in cord-like indurations slong the superficial veins over the legs and feet. Histopathologically, the deep dermal veins commonly showed luminal occlusions by thrombi, and inflarnmstory infiltrates of a fairly large number of lyrnphohistiocytes and a few giant cells in their walls and surrounding tissues. Cases 1 and 2 were with idiopathic type, and Cage 3was associated with Buergers disease. The systemic therapy with dipyridamole, nicotinamide, aspirin and piraicam had been tried with unsatisfactory results.

This retrospective study comprised patiens with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, Pildong hospital, Chung Ang university during the past 5 years from January 1994 to December 1998. The medical records of these patients (fractures) were reviewed and analysed in order to gain insight into a clinical pattern and understnad the therapeutic modalities. The following results were obtained: 1. The monthly incidence was highest in August and most common accident time was between 6:00 p.m and midnight. 2. The mean age of patients was 28.3 years, and age range was 3 to 69 years. The most prevalent age group was the third decade of life (42.9%). Males predominated more than female in the ratio of 4.1:1. 3. The most common etiology was assault (29.6%) followed by traffic accidents (28.5%), fall (23.1%), sports (7.9%). 4. 369 facial fractures in 277 patients were classifed. The most common sites were nasal bone, followed by zygoma, mandible, maxilla, orbit. 5. Associated soft tissue injuries were combined in 168 patients (60.6%), and fractures other than facial bone were developed in 61 patients (22%). 6. Treatment of facial bone fracture consisted of open reduction (42.6%), closed reduction (40.1%), and conservative treatment (17.3%). 7. The complication rate was 11.6% and the most common complication was the eye problem.

Short nose is characterized by decreased distance from the nasion to tip defining point and increased nasolabial angle with increased nostril show. Lengthening the short nose is arguably the most difficult operation in aesthetic rhinoplasty. We have described here a simple and easy technique that lengthen the short nose by using silicone implant has been popular among Asian for augmentation rhinoplasty. Through open rhinoplastic approach, wide undermining of the nasal skin is performed to allow redraping of the skin over the lengthened skeletal framework without excessive tension. Alar cartilage is released from upper lateral cartilage and relocated caudally. After relocation of alar cartilage, silicone implant is inserted in subperiosteal pocket and immobilized by nonabsorbable suture material at dorsal aspect of septal cartilage. Narrow caudal end of implant is sutured between medial crura of alar cartilage which were caudally rotated. This implant not only raise the nasion but can move the tip-defining point caudally by keeping the alar cartilage in new position. Tip graft is done with conchal cartilage. We have got the satisfactory result in cosmetic aspect without any complications.
