Cryopreservation of apple in vitro axillary buds using droplet-vitrification.

In vitro axillary buds of two apple cultivars, Pinova and Jonagold, were successfully cryopreserved by droplet-vitrification. In vitro axillary buds of cv. Pinova were subjected to PVS2 for 15, 30, 45, 60, 80 or 100 min, while Jonagold buds were treated with PVS2 for 15, 30, 45 or 60 min.

[Value of jejunostomy for immediate postoperative feeding in digestive surgery in elderly patients].

Without aiming at expanding this complementary method of enteral feeding to any seriously operated on people, the authors restrict this nutritional process to the patients operated on upper mesocolon - stomach-duodenal and biliary-liver visceral lesions - whether they are neoplastic, ulcerous or lithiasic, without reminding its current use in the esophagus surgery.

[Colo-duodenal fistula caused by cancer of the right colonic flexure treated by right extended hemicolectomy associated with a mucosal patch using a terminal ileal pedicled graft. Apropos of a case].

A considerable loss of substance of the duodenal wall makes its repair very difficult especially if this exceeds two-thirds of its circumference and is located around its entire second portion. Such a pathological or traumatic localization calls for extensive surgery-cephalic duodenopancreatectomy requiring several gastrojejunal, biliodigestive and the pancreaticodigestive shunts. If straightforward repair was possible, this could lead to stenosis and to a fistula producing complications and the death of the patient through peritonitis and hydroelectrolytic and metabolic imbalance.
