[Multiple sphincterotomies in the surgical treatment of cataracts in narrow pupils]. / Esfinterotomías múltiples en la cirugía de la catarata en pupila estrecha.

Deficient mydriasis of diverse etiology renders extracapsular cataract extraction and posterior chamber intraocular lens implantation technically difficult. Several techniques are available to improve surgical results when this problem is present. We have used multiple sphincterotomies in 6 patients with narrow pupils undergoing cataract extraction. We discuss the indications, intraoperative complications and postoperatory evolution of these cases.

New 5-hydroxy-2-indolecarbohydrazides as platelet aggregation inhibitors in ethylene glycol.

The effect of ethylene glycol on blood platelet aggregation was examined using a previously described method. This method also was used to investigate several derivatives of 2-indolecarbohydrazide in vitro. All compounds inhibited platelet aggregation induced by collagen, epinephrine, or adenosine diphosphate at concentrations below 5 x 10(-4) M.
