[Thymostimulin immunoprophylaxis in elective abdominal surgery]. / Immunoprofilassi con timostimolina in chirurgia addominale d'elezione.

The Authors report their experience of 121 patients who had undergone an elective abdominal operation and who had been previously considered under an immunological point of view and classified as anergic. The Authors have found a notable reduction of postoperative infection incidence in the 61 anergic operated patients who have been treated with Thymostimulin; they conclude by underlining the importance of careful consideration and eventual correction of immunological alterations of the patients of the patients who must undergo an operation.

[Experimental evaluation of 4 different suture materials in colo-colic anastomoses (in the rat)]. / Valutazione sperimentale di quattro differenti materiali di sutura nell'anastomosi colo-colica (nel ratto).

The Authors carry out an experimental comparative study on four different suture materials (collagen cromic, polyglactin 910, PDS and nylon), used to perform end-to-end colonic anastomoses. They assess the resistence to the endoluminar pressure. The results show that during the first four days the anastomoses performed with PDS display a vere high resistence, while those with collagen cromic exhibit still lower value than Vicryl and nylon. After eleven days the anastomoses with the PDS show most resistence again, but the other three materials get similar value.
