    [Show abstract] [Hide abstract] ABSTRACT: The "Merckognost Harntoff" strip method described in a previous paper was recently modified by the manufactures. An important alterations consisted in the method by which samples were applied to the strips, viz. using micropipetters rather than by dipping. In view of the findings in the comparative study reported, the results obtained on dipping are regarded as superior, the method also being easier to handle. However, the prescribed correction factor should be used.

    [Show abstract] [Hide abstract] ABSTRACT: Three simple photometers were tested for their suitability to determine concentrations of creatinine in small animal practice. Combination of the photometers with a "cuvette test" produced satisfactory results on comparison with a reliable reference method.

    [Show abstract] [Hide abstract] ABSTRACT: A method for the determination of proteins in canine urine is described, based on a combination of the Albustix and heat coagulation tests. As a reference system the Pesce and Strande method was used. The range of proteins in normal canine urine was 0–0.56 g. per 1,000 ml. The method is suitable for use by the general practitioner.The Pesce and Strande method gave excellent results and is recommended for use in suitably equipped laboratories.ZusammenfassungBestimmung der Eiweißkonzentration im Urin von HundenAuf Grund einer Kombination von Albustix und Hitzekoagulation wurde eine Methode zur Bestimmung der Eiweißkonzentration im Hundeurin ausgearbietet. Als Referenzanalyse wurde die Methode von Pesce und Strande angewendet.Im normalen Hundeurin schwankt die Proteinkonzentration zwischen 0–0,56 g pro Liter. Die Methodik kann auch in der klinischen Praxis angewendet werden. Die Methode von Pesce und Strande gibt ausgezeichnete Ergebnisse, sofern ein entsprechend ausgerüstetes Laboratorium zur Verfügung steht.RésuméDétermination de la concentration des protéines dans l'urine des chiensUne méthode de détermination des protéines dans l'urine de chiens est décrite; elle est basée sur une combinaison d'Albustix et du test de coagulation à chaud. La méthode de Pesce et Strande fut utilisée comme système de référence.Le taux normal de protéines dans l'urine canine varia de 0–0,56 g/litre. La méthode est applicable dans la pratique clinique. La méthode de Pesce et Strande donne d'excellents résultats et peut ûtre recommandée pour les laboratoires convenablement équipés.ResumenDeterminación de la concentración proteica en orina de perrosBasada en una combinación de Albustix y coagulación térmica, se élaboró una técnica para determinar las proteínas en la orina de perros. Como análisis de referencia se usó el método de Pesce y Strande.La concentración proteica oscila en la orina normal de perro entre 0–0.56 g. por 1000 ml. El mótodo se puede emplear en la práctica clínica. El procedimiento según Pesce y Strande ofrece resultados excelentes, recomendándose su uso en los laboratories provistos de equipo adecuado.

    [Show abstract] [Hide abstract] ABSTRACT: Two simple photometers were tested for their suitability for use in veterinary practice. Determinations of haemoglobin, glucose and total serum protein were studied using specially designed testing kits. The methods were found to be rapid, simple and reliable. Comparison of the results with those obtained using known standard methods showed a satisfactory correlation for haemoglobin and total serum protein. The results obtained on determination of glucose showed some minor differences which were possibly due to the different chemical methods used. Instruments as well as the methods used in testing are recommended.

    [Show abstract] [Hide abstract] ABSTRACT: To examine the suitability and reliability in field use of the "Merckognost Harnstoff" method in estimating the concentration of urea in the blood of horses, cattle, goats and dogs, the levels determined by this procedure were compared with those determined by an enzymatic (urease) photometric method widely used in laboratories. It was concluded from the results obtained that estimation using the "Merckognost Harnstoff" is sufficiently reliable for the rapid assay of urea in the blood under field conditions.
