HEMORRHAGE from the cut surface is inevitable in the partial resection of liver, pancreas, kidney and spleen. In partial hepatectomy and in partial pancreatectomy the leak of the bile or the pancreatic juice further complicates the cut surface. If the leak continues persistently after operation, it is detrimental to the peritoneum. The use of needles and sutures for stopping the hemorrhage and the leak of the bile or the pancreatic juice may cause additional hemorrhage and the retardation of operation time. To solve this problem, an adhesive, 98% ethyl cyanoacrylate monomer, was used. We have reported that the replacement of methyl radical by the ethyl in the side chain of cyanoacrylate monomer significantly lessens histotoxicity1,2 and that n-butyl, 2-ethylhexyl and isopropyl monomers have no less histotoxicity than ethyl monomer on histologic examination.3 EXPERIMENTAL SURGERY MATERIALS AND METHODS. —Experimental animals were 12 mongrel dogs. The right lobe of the

Direct infusion of ethyl cyanoacrylate monomer into the viscerocutaneous tubular fistula was curative when the fistula was narrower than 5 mm in diameter. A piece of flat rubber or silicone gauze was fixed by cyanoacrylate adhesive on the cutaneous opening of the wide tubular fistula. Gradually the diameter of the fistula shrank from 10 mm or greater to 5 mm or less. Thereafter, direct infusion of ethyl cyanoacrylate monomer into the fistula was curative. Covering of mucosal lips of the labial fistula with a flat rubber piece or silicone gauze by means of ethyl cyanoacrylate monomer or dimethylpolysiloxane failed to cure the labial fistula but relieved local dermatitis, dehydration, and electrolyte imbalance preoperative ly.

RENOVASCULAR hypertension is usually treated with an implantation of either bypass graft or patch graft. This method has been successful to some extent.1 However, we are not completely satisfied with it. The failures seem to have arisen from the fact that the renal artery lies deep in retroperitoneal space. Especially on the right side, the renal artery runs behind the inferior vena cava and this hinders delicate surgical manipulation. Not rarely the failure to establish sufficient blood flow in the renal artery ultimately leads to nephrectomy. Needless to say, reconstruction of the artery necessitates a precise technique. It is not recommended that such a maneuver be performed in a restricted surgical field or even behind the inferior vena cava which is vulnerable to factitial injury.Recent advancement in renal homotransplantation has shown that the nephrectomized kidney functions well after transplantation.2 It therefore occurred to us that the kidney

The polarized absorption spectrum of the conjugate base of 2-naphthoic acid was measured in a stretched PVA sheet. By comparing the polarized absorption spectrum with the results of the PPP calculations including a VESCF and variable β methods, we discussed the electronic structure of the conjugate base.
