Évaluer et comparer l’efficacité d’une injection sous-conjonctivale de bévacizumab et de la photothérapie dynamique (PDT) ou de leur association sur la réduction de la néovascularisation cornéenne.

Experimental evaluation of a new type of dacron graft, pretreated with mod ified mammalian gelatin, has been performed on the beagle dog. After grafting of the infrarenal aorta, dogs were monitored from three days to three months. Pretreatment with gelatin effectively avoided the need for preclotting and did not affect the normal healing of the prosthesis as compared with similarly tex tured not pretreated grafts.This graft, when applied in man as an abdominal aortic substitute, has yielded uniformly gratifying results (within a follow-up range of twenty to twenty-seven months).

Excision of small non-palpable breast lesions can be difficult and may result in the unnecessary removal of excessive surrounding breast tissue1. With this in mind a simple excisional biopsy technique for such lesions has been developed which employs intraoperative ultra-sonography to guide the extent of excision.
