[The preliminary results of research on salcatonin treatment in the surgical therapy of jaw cysts].

The results of research concerning a local and systemic treatment with salcatonin in surgical therapy of maxillary cysts are reported. A reduction in bone recovery time has been noted in the cases studied; this means a reduction in osteolytic area and a roentgenographic opacification of the same.

[The use of misoprostol in prevention of gastric disease from nonsteroidal anti-inflammatory drugs in oral-maxillofacial surgery].

The results of a clinical experiment with a new synthetic prostaglandin for the prevention of gastric lesions induced by NSAID: the misoprostol have reported. Twenty patients were treated with this drug and the results were compared to those obtained with the use of ranitidine in the same number of patients. The clinical experiment showed an excellent misoprostol-induced gastric protection which compared to ranitidine presents the advantage of a multiple and pathogenetically oriented action mechanism.

[Phenotype study of varieties of carcinomas originating in the oro-pharyngo-laryngeal mucosa. Anatomo-clinical considerations].

An immunohistological analysis with a panel of monoclonal and polyclonal antibodies was performed in 20 cases of squamous cell carcinoma originating in the oral cavity, oropharynx and larynx. The epithelial antigens were detected in all cases with variable patterns of positivity: cytokeratins and epithelial membrane antigen were positive in a high number of neoplastic cells in the carcinomas with a high grade of differentiation, whereas a lesser number of positive cells was observed in the poorly differentiated carcinomas. On the contrary the tissue polypeptide antigen was detected in a considerable number of neoplastic cells in the poorly differentiated carcinomas as well as in the fields with basal and cylindric cells.
