Tumour budding, uPA and PAI-1 are associated with aggressive behaviour in colon cancer.

Aims: The proteases PAI-1 and uPA play a major role in extracellular matrix degradation, which facilitates tumour progression. Tumour budding is a histomorphological expression of enhanced tumour cell migration.

Materials And Methods: To investigate their prognostic value for and correlation with colon cancer, a prospective study was performed.

[Effect of coronary flow reduction on the coronary flow distribution, the myocardial metabolism and left ventricular hemodynamics].

Myocardial blood flow, left ventricular performance, regional myocardial metabolites (ATP, CrP, lactate) and a-v differences of oxygen, lactate and pyruvate were determined in 6 open chest dogs with cannulated left coronary artery. A mean flow reduction from 92 to 43 ml/min/100 g heart weight resulted in marked heart failure accompanied by extensive flow reduction to the endocard with nearly 10 fold increase of lactate and a decrease of CrP content to 50% of control. In contrast, flow and metabolic parameters of the epicardial part changed only slightly.

[131-I cholesterol (19-C) in the functional and localization diagnosis of adrenal cortex disorders].

Results are reported of quantitative adrenal scintigraphy with 131I-cholesterol in 8 patients with normal adrenal function before and after ACTH-stimulation and cortisol-suppression respectively, in one case with an adrenal metastasis from a pulmonary cancer, in two cases with Cushing's disease and in 7 cases with Conn's disease. In normal cases and in patients with M. Cushing a diagnosis of adrenal cortical function is possible with this method but can usually be replaced by more specific biochemical studies of serum and urine.

[Exhalation diagnosis with C14 tagged compounds, methods and results].

The method and results of the 14C exhalation test for metabolic studies are presented. In patients under radiotherapy for malignant diseases (we consider radiotherapy to be a well defined metabolic disturbance), studies with 14C-carboxyl triglycerides, with 14C-glycincholate, with 14C-histidine and with 14C-uridyl reveal the extent of the metabolic changes and also how long it would take to return to the normal state. It is not yet well understood why a disturbace of glycincholate absorption persists for years after radiotherapy of the pelvis.
