[The use of lasers in end-to-end anastomosis of the uterine horn in the rat. Histological considerations]. / Uso del laser nella microanastomosi termino-terminale del corno uterino di ratto. Considerazioni istologiche.

The Authors have verified the utility of the Laser CO2 instrument for termino-terminal anastomosis of the uterine horns of the rat. In this study Laser tecnique is compared with the same traditional microsurgical operation. No significant difference was seen in the number of pregnancies nor fetuses born. On the contrary, hystological observation has shown lower reactivity in the group treated with Laser technique 10 days. In this group it was also noted that there was less formation of postoperative adhesions, and, during the operation, there was easier dissection of the tissues accompanied by lower blood loss and necrotic debris.

[Venous reconstruction using a fresh arterial patch in experimental microsurgery]. / Ricostruzione venosa con patch arteriosi freschi in microchirurgia sperimentale.

The Authors have studied the lower trombogenicity following interposition of an arterial patch in a venous termino-terminal microanastomosis. The microsurgical operation was performed on the femoral vessels of the rat. A tract, cm 0.8-1 long, of femoral artery was excised and after washing in Emagel solution, was interposed in the femoral vein of the opposite leg. The patency of the femoral vein was verified at the end of the anastomosis. We also studied the histological change of the arterial patch grafted both 10 and 30 days after the operation. A progressive reduction of the reactivity around the nylon sutures and an increasing venous metaplasia was found correlating with time.

[Vascular microanastomoses in the experimental and clinical transplantation of tube and ovary]. / Le microanastomosi vascolari nel trapianto sperimentale e clinico della tuba e dell'ovaio.

This work offers a review of the progresses achieved in both experimental and clinical fields about internal genital organs grafting. The Authors refer their own experience on the vascular microanastomosis and the grafting in rats. They particularly point out the difficulties and the problems they have met during their study. Microsurgical technic has allowed to achieve the viability of the microanastomosis controlled by hystological observations after 10 and 30 days.

[Experimental microsurgery operations on the rabbit fallopian tube]. / Modelli sperimentali microchirurgici sulla tuba di coniglio.

The authors show their experience in tubal microsutures in rabbits belonging to the New Zealand type. Three groups of seven rabbits each have been examined and for each group a different type of microsurgical operation has been carried out. Post operational checks where effected immediately afterwards and sometimes after the operation.

[Reversible sterilization with a physiological solution in the rat: preliminary note]. / Sterilizzazione reversibile nel ratto con soluzione fisiolo gica: nota preliminare.

In this paper the Authors present a technique of reversible sterilization of female rats. They used saline hot solution through cervix and uterine horns in 45 S.D. female rats. They divided the rats in three groups. The first group received a 43 degree hydrotubation, the second a 50 degree hydrotubation and the third a 60 degree hydrotubation. All the animals were mated several times and the litter sizes were studied. Biopsies were taken by uterine horns and histological results are discussed.
