The improvement in resolution, definition and contrast of the LC images and a clinical assessment of the diagnostic relevance of the procedure were scored. The use of LC improved the quality of the radiographs in 10 cases (83%) thanks to an improvement in the resolution (67%), definition (58%) and contrast (83%). The procedure was diagnostically relevant in 5 cases (42%), facilitating the detection of details not clearly visualised by previous conventional survey radiographs: a very thin foreign body responsible ofTRP, a mass in the ventro-caudal contour of the reticulum, the exact position of the foreign bodies. A consistency test for the x-rays was performed in a clinically healthy cow to confirm the improvement in the radiographic quality determined by the procedure. Although conventional imaging is often sufficient to confirm diagnosis ofTRP, the use of the LC improves the quality of reticular radiographs and in several cases can be fundamental for the identification of a thin foreign body or a lesion.","PeriodicalId":11154,"journal":{"name":"Deutsche tierarztliche Wochenschrift","volume":"1 1","pages":"429-435"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73237274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zum einen wurden neun Mastschweine mit gesunden Gliedmasen thermographiert mit dem Ziel, normale Temperaturwerte der Korperoberflache zu erfassen und den Einfluss des Faktors Umgebungstemperatur auf diese Messwerte zu analysieren. Zum anderen wurden die Korperoberflachentemperaturen von 25 Schweinen mit Verdacht auf Gelenkentzundungen an den Gliedmasen analysiert, um die Thermographie zu validieren. Alle Tiere wurden beidseitig thermographiert. Bei der Auswertung der Thermogramme wurde zwischen Zielbereichen (Tarsus, Carpus, Knie, Ellenbogen, Schulter) und Referenzbereichen (Ohrgrund, Unterbauch caudal, Medialseite der Vorder- und Hintergliedmasen) unterschieden. Die Oberflachentemperatur der Haut nahm sowohl fur die Ziel- als auch fur die Referenzbereiche mit zunehmender Umgebungstemperatur signifikant zu. Da die Temperaturdifferenz zwischen anatomisch symmetrischen Zielbereichen auch bei gesunden Tieren je nach Gelenk bei 28-38% der Messungen relativ gros war (> 1 K), eignet sich diese Methode der Auswertung von Thermogrammen nicht zur zuverlassigen Erfassung von Entzundungen. Auch anhand der Temperaturdifferenzen zwischen Referenz- und Zielbereichen konnte keine sichere Diagnose gestellt werden. Es wurden zwar zwei von funf pathologisch nachgewiesenen Gelenkentzundungen auch mit Hilfe der Thermographie identifiziert. Bei den chronischen Gelenkentzundungen konnten aber nur 9,5% (2 von 21) anhand der Thermogramme erkannt werden, und fur cirka 10% der Gelenke der neun aufgrund pathologischer Untersuchungen als gesund bestatigten Tiere wurde eine falsch–positive Diagnose gestellt. Aus diesen Grunden reicht die Thermographie als alleinige Methode zur Diagnose von Gelenkentzundungen bei Mastschweinen nicht aus. The aim of the present study was to assess the feasibility of using infrared thermography as a method for diagnosing inflammation of the leg joints in fattening pigs. Firstly, skin temperature measurements were made in nine healthy pigs by means of thermography to identify normal temperature values at different parts of the body and to quantify the effect of environmental temperature on these values. Secondly, in order to validate infrared thermography, skin temperatures were analysed in 25 pigs suspected to suffer from an inflammation of a leg joint. Thermal images of both body sides were taken from each individual. The images were analysed differentiating between target regions (tarsus, carpus, knee, elbow, shoulder) and reference regions (ear base, belly caudal, medial side of forelimbs and hindlimbs). With both types of regions, skin temperature increased significantly with environmental temperature.

Ultrasonographic examination revealed a large volume of fluid in the left half of the thoracic cavity. The right lung was almost entirely necrotic, and ultrasonography revealed intrapulmonary fluid containing echogenic fibrin masses. Centesis of the intrapulmonary fluid yielded an exudate. A large amount of anechogenic fluid was visible in the abdomen, and the liver was enlarged.The caudal vena cava was dilated and appeared oval rather than triangular on cross-sectional images. Because of the severity of the lesions, the heifer was euthanased and necropsied. Thorax and abdomen contained a large volume of fluid, and the liver was chronically congested.The hepatic veins of the right lobe of the liver were dilated and partially filled with pus. An abscess was also found in the right lobe of the liver. There were adhesions between the right lung and thoracic wall. A large part of the right lung had undergone coagulation necrosis. In the remaining right diaphragmatic lung lobe, there was a large abscess, which was attached to the caudal vena cava over an area of 4 centimetres. In this region, the caudal vena cava was filled with pus and completely obstructed.

Concentration response curves (CRC), the maximal attainable response (V max ) and the effective concentration 50 % (EC 50 ) for BeCh were calculated for the parameters area under the curve, maximal amplitude of the contractions, and basal tone. Bethanechol produced a concentration-dependent increase of all parameters. After incubation with AF-DX 116, BeCh still produced a significant concentration-dependent increase of all parameters in specimens of all locations, and a rightward shift of the CRC. After incubation with 4-DAMP, the effect of BeCh was almost completely blocked, and the contractile effect remained minimal.The results of this study emphasize the therapeutic potential of BeCh in spontaneous cases of cacal dilatation/-dislocation, where enhancement of motility in the spiral colon is targeted.","PeriodicalId":11154,"journal":{"name":"Deutsche tierarztliche Wochenschrift","volume":"19 1","pages":"171-177"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86818934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 60 cows, which were at least 120 days in their lactation, the healing process was compared with the biochemical profiles. In 141 cows 197 claw lesions were recorded. Diagnosed were only sole ulcers (38%) and white line lesions (62%). In the first and second half of the summer term, the number of claw lesions was equal, although more severe lesions occurred mainly during the second half (89%). The lesions were treated surgically and the affected claw was elevated on a wood block or a plastic shoe. Average time for formation of a close layer of horn was 14 days. A delayed healing process was observed in dairy cows with an milk yield over 5500 kg per lactation, as well as in the second half of the summer term. Cows with a delayed healing process had significantly higher concentrations of free fatty acids and beta-hydroxybutyrate, and higher plasma enzyme activities for AST than cows with adequate healing process. This indicates that cows with a relatively high milk production touch upon the limits of their physical capacity under harder conditions on alpine pastures, which may affect also the healing process of claw lesions.","PeriodicalId":11154,"journal":{"name":"Deutsche tierarztliche Wochenschrift","volume":"75 1","pages":"255-261"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82027544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
