[Preliminary scanning electron microscope (SEM) observations of the rat renal parenchyma after microdissection].
Rat kidneys weighting between 250 and 300 g. were treated in HCl. A single nephron observed through SEM shows that the above treatment doesn't interfere with the ultrastructural morphology of nephron.

[Heterotopic transplantation of rat liver. Preliminary observations with the scanning electron microscope (SEM)].
An eterotopic grafting of their livers has been made between two inbred rats. From 30 to 50 days later the livers has been observed through OM or SEM. In the first case (OM) there was evidence of vacuolar degeneration of liver cells gradually decreasing on the 50th day. In the latter case (SEM) the morphological appearance remained unchanged.

[Neoplastic involvement of the inferior vena cava].
Inferior caval vein invasion not infrequently complicates advanced neoplastic lesions. Primitive caval neoplasms (leiomyosarcomas) or other tumors such as renal carcinomas, pheochromocytoma, as well as liver, testis, and retroperitoneal tumors most likely cause caval invasion. In the past, caval invasion was a clear index of non operability, while today, a modern multidisciplinary approach allows to treat successfully even so advanced diseases. In the present report the Authors analyze the cases treated at the Dept. of Surgery of the University of Perugia, and review the most important international reports on this subject illustrating the new possibilities offered by IVC substitution with biological or artificial grafts.

[Primary choledocholithiasis after side-to-side choledochojejunostomy].
Primary choledocholithiasis represents a quite unusual sequela of biliary tract surgery. Primary stones originate in the common bile duct and are soft, smooth, with a yellowish or brown-reddish colour, reproducing the shape of the duct in which arise. The Authors report a review of the cases observed in the division of General and Vascular Surgery-Department of Surgery and Surgical Emergencies of the University of Perugia. From January 1988 to December 1993, 577 laparotomic biliary tract operations were performed, and in 8 cases a re-operation was needed. Among the latter, particularly interesting were 2 cases of primary choledocholithiasis occurred in two patients with bilio-digestive anastomosis previously performed, i.e. two side-to-side Roux-en-Y or Braun loop choledochojejunostomies, respectively. Therefore, primary lithiasis following a choledochojejunostomy occurred when the bilio-digestive anastomoses were performed with the indication of a curative re-operation on the biliary tract. On the contrary, most choledochojejunostomies are performed as a palliative procedure in patients presenting a low survival rate not allowing to develop a Sump Syndrome and a consequent choledocholithiasis, which are long-term complications.
