[Measurement of serum protein-bound hexose--an aid in the diagnosis and after-care of colorectal cancers?].

In a group of 80 patients with colorectal carcinoma and a control group of 103 persons Protein-bound Hexose (PHex) was measured in the serum. The level was, as reported previously by other authors, significantly elevated in the tumour group. The aim of this study was to compare the sensitivity of PHex with that of the oncofetal antigens CEA and CA 19/9. The sensitivity of PHex turned out to be clearly lower than that of CEA. It was about as high as the sensitivity of CA 19/9 in colorectal carcinoma. In view of these results there is no benefit to be expected from an introduction of the PHex determination into clinical practice.

Activities of APh, gamma-GT, GlDH and GPT and bile acid concentrations in serum after bile duct obstruction and cycloheximide in the rat.

The aim of this study was to investigate the effect of the protein synthesis inhibitor cycloheximide on the serum activities of gamma-Glutamyltransferase, Glutamate dehydrogenase and Glutamate pyruvate transaminase after bile duct obstruction in rats. The results showed that the increase of these enzyme activities after bile duct obstruction is further augmented by cycloheximide. Determinations of total bile acids in serum and liver showed that also the bile acid concentrations rise to a higher level after bile duct obstruction + cycloheximide than after bile duct obstruction alone. It is concluded that the effect of cycloheximide on the serum enzyme activities in extrahepatic cholestasis is produced via an influence on the metabolism of bile acids. This stresses the central role of bile acids for alterations of enzyme activities in extrahepatic cholestasis. Further, the effect of cycloheximide on bile acids after bile duct obstruction has not been reported before.

[The activity of serum cholinesterases following experimental choledochus ligation in the rat].

The activity of serum cholinesterase was measured over three days after ligature of the common bile duct in female Wistar rats. A specific effect of the ligature was observed on the third day postop.: the activity decreased. The delayed reaction can be explained by the long half-life of the enzyme. Further, in all operated rats (sham-operated, too) a decrease of activity on the first postop. day was noticed. Possible causes are an influence of the anesthetics or sequels of the operative trauma.

[Functional reconstruction by neurovascular muscle and myocutaneous flaps of the lower extremity].

The management of resurfacing problems is simplified in using free, microvascular flaps in complex trauma or tumor surgery. To restore motor function neurovascular muscle or myocutaneous flaps are imperative. Therefore 29 neurovascular latissimus dorsi flaps in 28 patients among more than 570 free tissue transfers have been applied to the lower extremity. One patient had a monoblock transfer, while another had bilateral latissimus dorsi flaps to both legs. Reanimation of the neurovascular flaps was perceptible at an average of 13.5 months. Of the 29 neurovascular muscle, or myocutaneous flaps 27 developed a joint excurvation according to muscle grading scale: M3 to M5.

Decrease in metacontrast masking following adaptation to flicker.

Selective adaptation was used to explore the characterisitcs of a metacontrast masking stimulus which contribute to its effectiveness in masking the test stimulus. Subjects adapted for 10 s to a configuration like the masking stimulus that was either continuously on or flickering. Following this they viewed a metacontrast presentation and estimated the brightness of the test stimulus. Prior adaptation to a continuously present stimulus did not appreciably affect metacontrast masking; however, masking was greatly reduced following adaptation to flickering stimuli. These results are consistent with recent models of metacontrast masking based on transient and sustained visual channels.
