RESUMO
In Botucatu, São Paulo, Brazil, 8 cases of primary tumors were encountered among 895 operated vermiform appendices: Five were colonic type adenocarcinomata and occurred above 40 years of age and three were carcinoids all in persons aged 25 or less. The diagnosis of appendical adenocarcinoma is almost never realized preoperatively. The importance of frozen sections in all suspicious cases is stressed since right hemicolectomy is the treatment of choice in cases of adenocarcinoma of the appendix. When malignant lesion goes unrecognized at initial operation, secondary hemicolectomy may be justified if histology shows invasion beyond the submucosa, at the line of ressection, or in lymph nodes. However, since the tumors is restricted to the mucosa, the patient must be followed with periodical radiology and endoscopy. In carcinoids limited to the appendix appendectomy is the treatment of choice.

The hemodynamic disorders resulting from the selective arteriography of celiac trunk and splenoportography were studied in 30 dogs. The systemic blood pressure and peripheral pulse rate were considered in these instants: before, during, immediately after and 10 minutes after the angiographic procedures. The analysis of the results obtained permit to conclude that: a) catheterism of the celiac trunk only, increase the systolic systemic blood pressure but does not change the dyastolic; b) during the injection of the contrast medium in the celiac trunk there is an increase of the systemic blood pressure (systolic and dyastolic); c) the selective arteriography of the celiac trunk as well as the splenoportography cause decrease of the systemic blood pressure (systolic and dyastolic) immediately after (1 to 70 seconds) the procedure; d) the decrease of the systemic blood pressure (systolic and dyastolic) is greater after the arteriography than after the splenoportography; e) the decrease of the systemic blood pressure (systolic and dyastolic) is transitory; 10 minutes after the realization of angiographies the systemic blood pressure return to the values observed before the examination; f) selective arteriography of the celiac trunk as well as splenoportography cause decrease of the peripheral pulse rate 10 minutes after the realization of the angiographic procedures.

Scintiscanning of the liver with Au198 was performed in 30 mongrel dogs. In 18 animals the scanning was performed after 3 different types of hepatic trauma: intraparenchymal hematoma, stab wound and lasceration of liver. In 12 days without hepatic trauma the scanning was performed with purpose to establish the pattern of the normal liver scan in the dog. Results indicate that scintiscanning of the liver is a good propaedeutic method in the evaluation of the presence and localization of traumatic hepatic lesion.
