1.A Case of Subungual Exostosis.
Korean Journal of Dermatology 1983;21(4):433-437
Subungual exostosis is not a true exostosis, but an outgrowth of normal bone tissue, which is traumatic disputedly in causative factor, involving mainly the great toe. We experienced a case which a hard nodule, l. 0 crn in diameter, of the great toe of the left foot, developed in a 24-year-old woman. Her lesion had begun about 6 months earlier, accompanying the dull pain or tenderness when wearing the shoes or walking. Confirmatory diagnosis was biopsy with biopsy and X-ray findings after nail avulsion. We performed the lesion with curettage on therapeutic trial without effect.

The present study has shown that immunohistochemical staining of the human placentas (5 first trimester and 20 full term placentas) for confirmation of the monocytic linease of its macrophage function. We used two macrophage associated glycoprotein; alpha-1-antichymotrypsin (A1Ac) and lysozyme (LSZ). The results from presence or absence of A1Ac & LSZ by immunohistochemical methods can be helpful to deceide the degree of differentiation of macrophage. In al the placentas examined a strong cytoplasmic reaction for A1Ac was seen in the Hofbauer cells, and the same cells of serial sections didn't stain for LSZ. The strong cytoplasmic reaction for A1Ac supports that Hofbauer cells are macrophage, but they didn't stain for LSZ, a bactericidal enzyme, we propose that these cells are not fully differentiated macrophage. The lack of LSZ may have some relevance to the pathogenesis of certain placental infections.

A retrospective morphological study was conducted on 1677 lymph nodes which were removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic carcinoma, chronic gastric ulcer, and superficial lymph nodes nuder the diagnosis of reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years from 1980 to 1984. The hematoxylin and eosin stained sections were examined to evaluate for any vascular changes. In selected cases further levels were prepared from the paraffin blocks for Gomori's reticulin stain. The vascular abnormalities were divided into 3 groups, such as hemangiomatoid, pan-nodal vasodilatation and miscellaneous types. The miscellaneous type included the proliferation of smooth muscle which encircled numerous small hilar arteries and veins. The results obtained were as follows: 1) The hemangiomatoid lesions were localized lesions which appeared to be associated with local malignancy, but infrequent in incidence. 2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to affect many nodes in a single group and is relatively associated with chronic gastric ulcer. 3) Miscellaneous lesion was nonspecific and appeared both local malignancy and chronic inflammation. 4) All three vascular reactions were somewhat more frequent in female than male.

We described here-in a 36-year-old male patient (case 1) with a severe form of keratosis palmaris et plantaris(Thost-Unna type) which was diffuse hyperkeratosis with hyperhidrosis on the entire surface of the palms and soles. His son, 8-year- old boy, showed symmetrical distribution of hyperkeratotic patches on the inner sides of both great toes(case 2). Therefore, it was suggested this genodermatosis occured in two generations of a family. The biopsy taken from the right palm of case 1 showed features of epidermal hyperplasia with hyperkeratosis, hypergranulosis and acanthosis. We tried the oral Vit. A therapy(50,000 unit, daily) in case 2. The hyperkeratotic lesions became slightly improved in 4 months after therapy.

Genus of aspergilli are ubiquitous saprophytic molds in nature, which are recognized about 700 species, at least eight are pathologic for human. Pulmonary aspergillosis is rare disease, most frequent presenting as secondary invasion, and aspergillosis of the nasal cavity is the most common sites of the extrapulmonary aspergillosis. Predisposing factors for pulmonary aspergillosis are chronic lung disease, tuberculosis, antibiotics, cytotoxins and neoplasia, hematologic disorders, and histoplasmosis etc. Authors have experienced 10 cases of pulmonary aspergillosis and a case of aspergillosis of nasal cavity in Dept. of Pathol. Chosun univ. hospital and christian hospital from Feb. 1981 to July 1984. Patient of pulmonary aspergillosis are received surgical resection and survived well without complications.

BACKGROUND AND OBJECTIVES: The goal of this study was to examine the safety and feasibility of a primary (direct) stenting in acute myocardial infarction (AMI). In the treatment of AMI, Percutaneous transluminal coronary angioplasty (PTCA) has documented superior reperfusion rate and improved clinical outcomes than thrombolytic therapy. However, there are several limitations of PTCA, such as recurrent ischemia in 10 to 15%, reinfarction in 3 to 5% and restenosis in 30 to 50% of patients. There are several reports that, compared with PTCA, the implantation of coronary stent has been shown to reduce angiographic restenosis and improve late clinical outcomes. But in general, stenting has been contraindicated in thrombus containing lesion due to the risk of subacute thrombosis. With advance in technique and the recognition of the importance of adequate platelet inhibition, the incidence of subacute thrombosis has fallen in patients with acute coronary syndrome and thrombus laden lesion. Methods and Results: In our study, primary stenting was performed in 42 patients of AMI. There are 6 cases (22.5%) target lesion restenosis during the follow up coronary angiography (150+/-86day) and no in-hospital death. Three cases (7.1%) of them require revascularization including two re-PCTA and a coronary artery bypass graft for the recurrent ischemic symptoms. There were no reinfarction and death after discharge. Six-months event free survival reate was 85.7%. CONCLUSION: Primary stenting is safe and feasible in the majority of patients with AMI and results in excellent mid-term outcomes compared with PTCA.

BACKGROUND: Bupivacaine is a potent, and commonly used, long acting local anesthetic. If accidentally injected into the systemic circulation, bupivacaine can cause lethal dysrhythmias and circulatory collapse. Attempts to treat bupivacaine induced cardiac toxicity have been varied and controversial, and they have not been very successful. The aim of this study was to investigate the electrophysiologic effects of bupivacaine in Purkinje fibers. METHODS: Effects of bupivacaine on the membrane potential were studied in 12 isolated canine Purkinje fibers. Purkinje fibers from ventricle were dissected and mounted in a tissue chamber perfused with Tyrode's solution. Transmembrane potentials recorded through glass microelectrodes filled with 3M KCI in the beating or quiescent Purkinje fibers during infusions of bupivacaine at concentratons of 3*10/-7M,10/-6M, 3*10/-6M,10/-5M, and 3*10/-5M. RESULTS: Bupivacaine reduced action potential druation in a dose-dependent manner. Bupivacaine produced a decrease in intracelullar sodium ion activity in driven(1Hz) and quiescent canine Purkinje fibers. Bupivacaine-induced hyperpolarizaton of diastolic membrane potential in quiescent Purkinje fibers was dose dependent, and the hyperpolarization by bupivacaine was attenuated by depolarization induced by high potassium extracellular concentration in part. CONCLUSIONS: These results suggest that bupivacaine decreases the fast inward sodium current, and inhibits pacemaker current in canine Purkinje fibers.
