A girl aged 18 years and 1 month, had a Angle's Class Iff malocclusion, characterized by anterior crossbite, anterior crowding, and constriction from right lower 2nd p emolar to right lower 2nd molar This ~i5 5s patient underwent scaling and 84148 extraction, and multibanded system was placed. After 14 months, anterior crossbite and crowding was corrected, andbothdental arches were improved. After 6 months from debanding, band space disappeared, and any relapse was not detected.

Essential hypertension is an important public health problem in Korea-being common, asymptomatic, easily treatable, and often leading to lethal complication in left untreated. The number of patients with hypertension has been significantly increased, and this factor may be an importnat one responsible for the increase in cardivascular mortality during past 20 years in Korea. As the drug therapy for hypertension needs longer period, it is very important to evaluate the efficacy and the adverse effects. Thirty patients(17 men and 13 womon) with essential hypertension were evaluated in this study. All patients had received oral Isradipine 1.25~2.5mg b.i.d. for 8 weeks. 1) The systolic and diastolic pressure were decreased significantly(166.8+/-9.0mmHg vs 147.3+/-12.0mmHg, p<0.001 and 100.3+/-4.0mmHg vs 90.3+/-6.1mmHg, p<0.001, respectively) 2) Heart rate, body weight, laboratory tests, chest X-ray, ECG studies were not changed significantly. 3) The systolic pressure was lowered by 20mmHg or more in 17 cases(56.7% of total), and the diastolic pressure was lowered by 10mmHg or more in 20 cases(66.7% of total) at 8 weeks after Isradipine administration. 4) The adverse effects of Isradipine were edema in 3(10%), constipation in 2(6.7%), headache in 2(6.7%), and insomnia, dizziness and dry mouth in 1 patient respectively, and none of them discontinued Isradipine administration due to adverse effects. In many patients with essential hypertension there is an effective response to Isradipine, even though there may be some mild adverse effects.

After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).

Leiomyosarcoma of the prostate is a rare malignant tumor. It originates from the smooth muscles of the prostatic gland and is usually found during old ages. Prognosis is usually poor especially in childhood. We report a case of leiomyosarcoma of the prostate measured 320gm in 64 years old man.

We describe a case of an acute heart transplant rejection treated with triple immunosuppression and plasmapheresis, resulting in evidence of improved clinical manifestation and hemodynamics. This case suggests that plasmapheresis may be useful in the treatment of possible acute humoral(vascular) rejection in heart transplantation.

OBJECTIVE: Immunofluorescence microscopy including confocal laser scanning microscopy and electron microscopy were used to study the production of fibronectin, tenascin, and laminin in the cumulus-corona (CC) cells surrounding mature, unfertilized oocytes after ovulation in view of their presumptive importance in the coordination of the processes leading to fertilization and early embryo cleavage, including the final maturation of the ovum, the sperm-egg interaction, and the complex biochemical mechanism between the ovum and the oviduct. METHODS: Mature oocyte-cumulus complex (OCC) was cultured for 24 and 48 hour and fixed in 3.7% formaldehyde. Specimens were incubated with a mixture of primary monoclonal antibodies recognizing different epitopes of fibronectin, tenascin, and laminin, and then with a mixture of secondary antibodies containing FITC, TRITC, and Cy-5 conjugated antibodies. Observation was made by confocal laser scanning microscope equipped with epifluorescece optics. Transmission electron microscopy were used to observe the OCC at 24 and 48 hours after cultrue. RESULTS: The immunocytochemical date demonstrated that CC masses are capable of producing fibronectin and tenascin but their production is heterogeneous in the CC population. Immunoreactivity to fibronectin and tenascin was shown mostly by inner corona cells, and the intensity of immunofluorescence decreased from the central corona cells to the peripheral cumulus cells. Colocalization of fibronectin and tenascin was evident in most CC cells. Moreover, fibronectin and tenascin immunoreactive material was observed in the intracytoplasmic areas, at the plasma membrane level as well as in the extracellular matrix. Whereas, laminin immunofluorescence was found around plasma membrane and extracellular area, but a intracytoplasmic reaction was rarely observed. The distribution of laminin immunofluorescence was similar to that of fibronectin and tenascin, but in some cumulus cells, colocalization between them was not found. Ultrastructurally, cumulus cells projected numerous long, thin microvilli into the intercellular area and some micovilli penetrated into zona pellucida. The inner layer of the cumulus mass was loose arrangement of relatively uniform, small cells with widened intercellular spaces, whereas in the outer layer, cumulus cells are rather larger in size and compact arrangement by narrow, irregular spaces. A small and large linear gap junctions were easily found at cell contacts. The cytoplasm of most cells had abundant organelles typical of steroidogenesis: numerous mitochondrias, a well-developed smooth endoplasmic reticulum, electron dense lipid droplets, and bundles of microtubules and microfilaments. Rudimentary disrupted basal lamina along the cytoplasmic border was rarely seen in a few inner conora cells. CONCLUSION: Even though the functional role of these extracellular matrix proteins remains still unclear, it is reasonable to suggest that they are necessary in various steps of the reproductive process. Cumulus cells appears to be a heterogeneous and dynamic system for suitable microenviroment of fertilization. And functional differences between corona and cumulus cells during the oocyte denudation may be accounted for particular distribution of these adhesive proteins and steroidogenesis-related organelles.
