Morphological investigation of the porcine liver directly following preservation with Euro-Collins, University of Wisconsin and Bretschneider's HTK solution.

In order to study perfusion effects of different liver preservation methods on liver structure, porcine livers were perfused with either Bretschneider's HTK (Histidine Tryptophane Ketoglutarat) solution, Euro-Collins (EC) solution or University of Wisconsin solution (UW) according to the respective recommended protocols. Subsequently, together with a group of unprotected livers, all organs were examined by light and electron microscopy including computer assisted morphometry. The width of the space of Disse, the continuity of endothelial cells and the ultrastructure of the hepatocytes were not impaired after cold perfusion with any of the 3 solutions. However, we found considerable differences between the groups with respect to removal of blood cells from liver sinusoids. Livers flushed according to the HTK-protocol had the lowest residual blood cell content followed by the livers of the EC- and the UW-group. Centrilobular regions of the liver lobules were generally better washed free of blood than periportal zones. Computer assisted morphometry did not reveal any significant difference between the size of hepatocytes of EC-, UW- and HTK livers. Only the hepatocytes of normothermic control livers (biopsy samples) were 10% larger than hepatocytes of cold flushed groups. None of the protective perfusion protocols showed structural signs of perfusion injury.

[Formation and degradation of triademinol after the use of triadimefon in a wheat monoculture].

During two vegetation periods, the behaviour of the triadimefon metabolite, triadimenol, in different plant parts of winter wheat and in soil was investigated. The fungicide Bayleton DF (triadimefon + captafol) was applied at the beginning of earing. Different ratios of triadimenol-A/-B were found in individual plant parts. Triadimenol-A predominated in the two uppermost leaves, and triadimenol-B in the roots and in the soil. No residues of triadimenol were found in grain at harvest time (detection limit 0.01 mg/kg).

[Behavior of captafol residues after prolonged application in a wheat monoculture].

In a 4-year study, the behaviour of the residues of the fungicide captafol in different plant parts of winter wheat and in the soil was investigated. The fungicide Bayleton DF (captafol + triadimefon) was applied at the beginning of earing. Captafol residues clearly showed a high dependence on weather conditions in all examined aerial parts of the plant. After a 9-year application of captafol, there was no evidence of an enrichment of residues in the soil. At harvest, captafol residues in grains always were below the maximum residue limits of 0.5 mg/kg established in West Germany.

[Sonography as the basic diagnostic method in cholelithiasis].

The author analyzes a group of 200 patients who all were indicated for operation of the gallbladder, based on ultrasonic and radiological preoperative diagnostic examinations. He draws attention to the great diagnostic accuracy of sonography, which was 96.5% in his group. Radiological methods are of equal accuracy but have a number of disadvantages. The diagnostic accuracy is enhanced by mutual combination of the two methods in controversial cases. The author concludes from his work that sonography ought to be the primary examination when disease of the gallbladder is suspected. Classical radiological methods should be a supplementary method which increases the diagnostic accuracy of biliary disease and thus reduces to a minimum incorrectly indicated surgical revisions.
