1.Postmortem Change of Adhesive Forces Between the Retina and the Retinal Pigment Epithelium.
Journal of the Korean Ophthalmological Society 1993;34(2):111-116
Adhesive forces between the retina and the retinal pigment epithelium, which is mainta ined by active mechanisms unique for living animals, deteriorates rapidly after death and leads to spontaneous retinal detachment. Change of retinal adhesiveness in rabbits after death was investigated using a new method. Retinal detachment was induced by applying various levels of aspiration power from 0 to 1OO mmHg to the vitreous cavity using a vitrectomy instrument immediately after the rabbit was killed without enucleation. And the time required for creating the retinal detachment was measured. Retinal adhesiveness deteriorated and spontaneous retinal detachment occurred 28 minutes and 35 seconds after death confirming the active adhesion between the retina and the retinal pigment epithelium before death Increase of aspiration power led to shortening of time required for creating retinal detachment. From aspiration powers of 0 to 100 mmHg, the common logarithm of time required for retinal detachment was inversely proportional to the aspiration power [IogY = 1.45215 - 0.01113X, (R2=0.99041), X: aspiration power (mmHg), Y: time required for creating retinal detachment (minutes)]. Thus, presumed time of retinal detachment could be estimated between the aspiration powers of 0 to 100 mmHg.

We reviewed the clinical and hemodynamic studies in 10 patients with the isolated congenital mitral insufficiency. The patients ranged in age from 6 months to 16 years at the time of diagnosis and the incidence was 0.26% among the total congenital heart disease proven by cardiac catheterization and angiography. In two cases anterior mitral cleft was demonstrated by 2-D echocardiography and/or operation. In two cases left coronary artery was originated from pulmonary artery. Eight cases out of ten presented symptoms indicating varying degrees of left ventricular failure. Apical systolic murmur was heard in all except one, who had only triple rhythm. The electrocardiograms revealed left ventricular hypertrophy in 8 cases and biventricular hypertrophy in 2 cases. Roentgenographically left atrial enlargement was observed in 4 cases. Left arterial and ventricular dimension were increased in 7 cases by echocardiography. In 5 cases of them, pulmonary artery wedge pressure or left atrial pressure was increased. One patient died in congestive heart failure at the age of 10 months and one patient died postoperatively. Other 4 patients have been managed with medication without difficulty.

The double-chambered right ventricle is congenital or acquired cardiac anomaly, which is characterized by aberrent hypertrophied muscular bands that divide the right ventriclar cavity into two different pressure chamber. This anomaly can complicate the natural history of patient with isolated ventricular septal defect. We experienced two cases of cases of acquired DCRV, which confirmed by two separate cardiac catherterization and angiography. The purpose of this report is to show that the aberrant muscular bands may be nonobstructive in early infancy and that the obstructive effect is developed with time as the bands become progressively more hypertrophied.
