Diabetic cataracts and flavonoids.

Oral administration of quercitrin, an inhibitor of aldose reductase, leads to a significant decrease in the accumulation of sorbitol in the lens of diabetic Octodon degus. The onset of cataract is effectively delayed when quercitrin is continuously administered. Thus in these diabetic animals, as in galactosemic rats, the use of an effective aldose reductase inhibitor impedes the course of cataract development. These observations support the hypothesis that in diabetes, as in galactosemia, aldose reductase plays a key role in initiating the formation of lens opacity.

Pulmonary regurgitation following total correction of tetralogy of Fallot.

A method is described for quantifying pulmonary regurgitation. This method is based on a comparison of the right and left ventricular stroke volumes which are determined from biplane angiocardiograms. These techniques were applied to study 18 postoperative patients with tetralogy of Fallot. In patients with an outflow patch, regurgitant fraction was well correlated with regurgitant area. The RVEDV/LVEDV ratio was also correlated well with regurgitant fraction. Although majority of patients maintained normal RV ejection fraction, there were small number of patients with large regurgitant fraction and decreased RV ejection fraction.

Optimal size of outflow patch in total correction of tetralogy of Fallot.

Hemodynamic and angiocardiographic studies were performed in postoperative patients with tetralogy of Fallot. Pressure gradient between the right ventricle and pulmonary artery was correlated with the narrowest area in the pulmonary arterial pathway. Regurgitant fraction was also correlated with regurgitant area which was determined by preoperative area of the pulmonic annulus and width of the outflow patch. Follow-up study of postoperative patients with tetralogy indicated that those with pressure gradient less than 20 mmHg and regurgitant fraction less than 15% could be considered ideally corrected. A table was constructed for determining the most appropriate width of the outflow patch for the ideal correction.
