A total of 33 German Landrace and Mangalitza pigs ranging in age from 4 weeks to 1.5 years were used for the determination of creatine kinase (CK) activity in blood serum and the histological, histometrical and immunocytochemical examination of 10 different skeletal muscles. The results show that a computer-aided histometric analysis of skeletal muscle fibers with special regard to their coefficient of variation and the interquartile range is not valuable for the diagnosis of myopathy in pigs. This contradicts the results reported in other species, where the grade of myopathy was found to correlate positively with the coefficient of variation. Using an antibody against fetal skeletomuscular myosin in immunocytochemistry, an age-dependently varying mixture of small myofibers of a physiological tapered and a pathological regenerating type was observed in porcine muscles, resulting in a relatively constant coefficient of variation of between 30-40% in skeletal muscles over the entire age range examined. In healthy porcine skeletal muscles, fetal myosin is only expressed prenatally. Thereafter, it is reexpressed only from the age of 16 weeks on and exclusively in cases of stress-induced myopathy. Therefore, the still controversial existence of a postnatal hyperplasia of skeletal muscle fibers in pigs must be rejected. The immunocytochemical detection of fetal myosin in skeletal muscles of adult pigs is the first reliable and sensitive method for diagnosis of stress-induced myopathy in pigs including latent forms of the disease.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

{"title":"[The therapy of hypovolemic shock in cows with right-sided abomasal displacement].","authors":"L Goetze, M Müller","doi":"","DOIUrl":"","url":null,"abstract":"In this trial, the effect of supplementary administration of the opioid antagonist Naloxone was tested, in comparison to infusion of Ringer's-solution only, in the treatment of hypovolemic shock in cows suffering from right-sided abomasal displacement. Twenty cows were selected by several criteria (pulse rate greater than 95/min; plasma chloride content less than 90 mmol/l; body temperature less than 39.5 degrees C) and alternatively assigned to the Naloxone group and the control group. All animals were treated surgically by the usual clinical method. After opening the abdominal cavity paralumbally from the right, intravenous administration of 13 l of Ringer's-solution was started and continued for about 5 hours. In addition, the cows of the experimental group received 0.75 g Naloxone as an intravenous bolus before, and 1 g Naloxone dissolved in 7 l fluid during the first hour of the permanent drip infusion. Further treatments (additional fluid therapy or administration of purgatives and ruminomotorics on the following days) were given according to the condition of the animal. The evaluation of efficacy was done in regard to the clinical (course of disease), and clinicochemical (e.g. hemogram, blood gas analysis, plasma chloride, plasma lactate) parameters as well as to blood pressure. No statistically significant differences were found between both groups. Only nine of the twenty cows were sent home cured, one patient of each group died one day after surgery, and the remaining 9 animals had to be sent to the slaughterhouse within 3 to 22 days after surgery after only transient improvement. These results suggest, that under the conditions described, conventional fluid therapy is equivalent to fluid therapy with addition of Naloxone. Hypoxic damage of the abomasum caused by its displacement and the subsequent hypovolemic shock are discussed as main causes for the poor postsurgical prognosis of right-sided abomasal displacement.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

The animals were kept at an environmental temperature of 28 degrees C and fed with Altromin Standard Diet. The two athyreotic groups were only insignificantly different with regard to the RNSV. Their RNSV was also only insignificantly different from the RNSV-minimum observed in rats fed a non-protein diet in an earlier study. In keeping with findings in those animals the intraspecific body mass exponents in the athyreotic groups were only insignificantly different from the values of b = 0.75. The results presented confirm the hypothesis that the value b = 0.75 calculated for the intraspecific body mass exponent reflects a causal relationship between the RNSV and the body mass, that is not influenced by further variables. Apparently this value can be determined from the thyroid independent part of the RNSV. The results also support the suggestion that feeding a non-protein diet eliminates the influence of the thyroid on the RNSV at least temporarily.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

Selected metabolites of energy metabolism].","authors":"N Sandner, M Stangassinger, D Giesecke","doi":"","DOIUrl":"","url":null,"abstract":"In order to study mechanisms in ruminants responsible for glucocorticoid-induced hyperglycemia the effects of a single intravenous dose of a glucocorticoid on energy metabolism were investigated by measuring plasma levels of glucose, lactate, free fatty acids (FFA), 3-hydroxybutyrate (3-HOB) and acetoacetate (AcAc). Experiments were performed on four castrated male African pygmy goats at two metabolic states: \"fed\" with a single daily meal of hey and \"fasted\" with starvation for 3 days. The untreated goats served as their own control. The glucocorticoid application to fed animals resulted in an increase in glucose level (+43%) lasting more than 11 h and an irregular increase of lactate. The concentration of 3-HOB was increased especially before feeding (+64%). In contrast, FFA were decreased (-27%) the second day after glucocorticoid application. In fasted goats the glucocorticoid also caused an increase in glucose level (+25%). The effect was smaller than in fed animals. Concentrations of FFA, 3-HOB and AcAc were 10, 20 and 35% lower than those of untreated goats. With regard to the antiketotic use of glucocorticoids the decrease of plasma levels of FFA and ketone bodies in starving animals is of special importance. Obviously the animals were able to use glucose again as a main energy source instead of FFA.","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.
