Tibia segmental defect healing in sheep were clinically, radiographically and histologically evaluated. Twelve young sheep aged four to five months were divided into two groups, G1 and G2. A 3.5 cm long segmental defect was created in the right tibial diaphysis with maintenance of the periosteum. The bone defects in both groups were stabilized with a bone plate combined with a titanium cage. In...

The effects of an altered content of dietary iodine and fat on the development of N-nitrosomethylurea-induced mam many tumors in rats were studied and correlated with thyroid and pituitary function studies. In three separate experiments, animals fed a semisynthetic diet containing 11.8% fat had an earlier time of tumor appearance and greater tumor burden than did controls maintained on a diet c...

The autoradiographic [14C]deoxyglucose method for quantitative determination of local cerebral glucose utilization (LCGU) was used to study the compensatory process following hemilabyrinthec tomy in adult cats. In the critical stage when the cats were uncompensated, LCGU in the deafferented vestibular nuclei was well below that of the intact side. Increased LCGU was seen in contralat...

For a number of years the anterior hypophysis has been known to play an important r61e in the regulation of body growth. I n general, the effects of hypophyseal secretions on growth have been found to be of a stimulative character. The growth stimulating or inhibiting action of such hormones is demonstrated most precisely by the changes they elicit in those tissues which normally undergo the mo...

Data from the literature report a retrieval success rate of 85%, with the remaining 15% requiring surgical removal [2]. The choice of retrieval technique is dependent on several factors, including biliary ductal dilatation, depth of stent migration, distal stent impaction, and biliary stricture distal...

esophagectomy are associated with high morbidity and mortality [1,2]. We pres− ent here a patient who had a subtotal esophagectomy with gastric interposition because of esophageal adenocarcinoma. Anastomotic leakage occurred and was treated by endoscopic applications of fi− brin glue. One month after discharge she presented with a large (2.5 cm ” 5 cm) ia− trogenic esophagotracheal fistula.
