Regional left ventricular dysfunction is common in patients with coronary artery disease and accurate analysis of regional dysfunction is of particular interest. For the quantitative assessment of regional dysfunction, we measured regional ejection fraction by radial sector division method in 19 patients with acute myocardial infarction and 13 normal controls who had multigated blood pool scan. And two independent observer analyzed regional wall motion using 5 point grading system in 18 patients undergoing radionuclide ventricular cineangiography. The results obtained were as follows : 1) Regional wall motion scores for the gated blood pool study agreed completely in 72 of 108 segments (66.7%) and agreed within 1 grade in 88 of 108 segments(81.5%) and agreement rate is lowest in the septal area. 2) Global left ventricular ejection fraction was 63.2+/-4.2% in normal controls, 36.6+/-6.8% in extensive anterior wall infarction group and 52.6+/-9.7% in inferior wall infarction group. The value of extensive anterior wall infarction group was significantly lower than that of inferior wall infarction group(p<0.005). 3) Regional left ventricular ejection fraction by radial sector division method in normal control group were as follows : area 1 ; 56.5+/-6.7%, area 2 : 77.9+/-4.8%, area 3 ;84.3+/-5.5%, area 4 : 76.8+/-6.6%, area 5 ; 84.7+/-7.6%, area 6 ; 85.9+/-11.2%, area 7 ; 75.5+/-12.3%, area 8 ; 74.9+/-14.0%, area 9 ; 75.5+/-8.8%, area 10 ; 54.2+/-11.0%, 11 ; 34.5+/-16.3, area 12 ; 37.1+/-18.0%. 4) Mean regional ejection fraction in 7 patients with anterior wall infarction showed significantly lower values in area 4 to area 8, and in area 2 to area 5 in case of inferior wall infarction group. 5) We thought that regional ejection fraction obtained by radial sector division method is valuable index for the management and evaluation of patients with coronary artery disease.

Pulmonary artery sling is a rare and potentially lethal vascular anomaly wherein the anomalous left pulmonary artery arises from the posterior aspect of the right pulmonary artery and passing to the left lung between the trachea and the esophagus which causes respiratory distress in infants and children due to the extrinsic compression of the airway by the anomalous vessel. Associated anomalies are common, particularly those of the tracheobronchial tree. The most common lesions are hypoplasia of the distal trachea and right main stem bronchus. About 50 percent of patients have cardiovascular anomalies, such as in the left superior vena cava, atrial septal defect, ventricular septal defect, patent ductus arteriosus, aortic arch anomalies, tetralogy of Fallot 1 etc. We experienced a case of a 6-year-old boy who showed dyspnea and frequent pneumonia. He was diagnosed with pulmonary artery sling associated with left bronchial stenosis, patent ductus arteriosus, and left superior vena cava which was parven by echocardiographic examinations, spiral computerized tomography of the chest and cineangiography. We report this case with related literature.

To create an experimental glaucoma model in rabbit and to study the effect of elevated intraocular pressure (IOP) on rabbits ocular tissues, we treated trabecular meshwork of 7 adult pigmented rabbits with Q-switched Nd:YAG laser. And then we studied the IOP lowering effect of topical verapamil in experimental glaucoma model. The IOP and outflow facility were measured with an applanation pneumotonograph (Alcon, Texas). During sustained rap elevation, 50ul of 0.25% verapamil was instilled in one eye and normal saline in the fellow eye. The IOP was measured 1, 2, 4, 8 hours after instillation. The measurement was repeated twice at 2 weeks interval. After 5 weeks, the IOP increased from an average baseline IOP of 16.6mmHg to 25.51mmHg, an increase of 55.6%. The outflow facility was decreased from 0.21 microliter/min/mmHg to 0.09 microliter/min/mmHg. There were statistically significant reductions in IOP in both verapamil and placebo-treated eyes(p<0.05). The reduction was greater in verapamil-treated eyes than in placebo-treated eyes(p<0.05). Maximal reduction of IOP was observed 2 hours after single-drop of verapamil, with significant reduction of IOP up to 4 hours duration(p<0.05). During the observation period of this study, cupping of the optic nerve head developed. Histopathologic examination revealed extensive scarring of the anterior chamber angle structure. There are marked hyaline degeneration of retinal ganglion cells in temporal retina.

Malignant chondroid syringoma, previously called "mixed tumor of the skin of the salivary gland type"is a fairly uncommon type of sweat gland tumor. Malignant chondroid syringoma frequently arises from the trunk and extremities, whereas the benign tumor is common to the head region. The present case occurred in a female. The malignant nature of the tumor was evident from repeated recurrences after excision of the mass and histopathological study. Lack of response to radiotherapy and chemotherapy led to widespread metastasis. We report a case of malignant chondroid syringoma with lung metastasis in a 39-year-old female patient and response to chemotherapy. We also reviewed the literatures of malignant chondroid syringoma.

Nerve fiber bundle index(NFBI) is a new index which detects visual field depression in 21 nerve fiber bundle zones, reflecting the topographical arrangement of visual field defects. We applied this index to 39 eyes with normal visual field and 131 eyes with early glau-comatous field defect(mean defect Area Under Curve ; Depression ; Glaucoma* ; Nerve Fibers* ; ROC Curve ; Visual Fields

The Scheimpflug photography was used to evauate objectively changes in lens opacity at a month interval in 143 eyes of 78 patients affected by early cataract. from Dec. 1993 to Dec. 1994. A total of 48 patients were treated daily with 1.5g bendazac-lysine, and 30 patients constituted the control group. We checked visual acuity and analyzed change of lens opacity by using axial densitometry and retroillumination of Scheimpflug photography after Bendaline(R) medication up to 9 months After treatment, improvement or no change of subjective visual acuity was observed in 65 eyes(78.3%) of treated group, whereas decrement in 35 eyes (58.3%) of control group. In the axial densitometry, the nuclear opacity began to improve after 3 months of medication and opacities of lens between anterior supranucleus and posterior capsule were statistically significant improved after 5 months of medication (p<0.05). There's no correlation in the change of opacity area under retroillumination (p>0.05). The result show that bendazac lysine may be effective in improvement of visual acuity and delay the formation of lens opacity in early cataract.
