We sought to determine whether prolactin (PRL) could influence the neutrophilic inflammation that characterizes chronic mastitis. Most of the genes encoding inflammatory proteins depend on the nuclear factor kappa B (NF-kappa B) for their expression. We addressed the hypothesis that immunomodulatory activities of PRL might arise from an increase in NF-kappa B activity. MAC-T cells, a bovine mammary epithelial cell line, were stimulated with increasing concentrations of bovine PRL ( 1, 5, 25, 125, and 1,000 ng/mL). Level of NF-kappa B binding activity was measured and mRNA was evaluated for IL-1 beta, IL-6, IL-8, granulocyte-macrophage colony-stimulating factor (GMCSF), IFN-gamma, and tumor necrosis factor (TNF)-alpha, cytokines known to require NF-kappa B for their maximal transcription. Prolactin activated NF-kappa B; maximal NF-kappa B activation was weaker with PRL than with TNF-alpha at 30 or 180 min poststimulation. In addition, PRL significantly amplified, in a dose-dependent manner, mRNA expression of IL-1 beta, IL-6, IL-8, GMCSF, and TNF-a. We measured PRL concentrations in blood and milk from healthy and chronic mastitis-infected cows, and studied the relationship between the PRL concentration and the degree of inflammation in the mammary gland as indirectly assessed by somatic cell counts (SCC). Plasma PRL did not differ significantly between healthy and chronic mastitis-affected cows (63.7 and 67.5 ng/mL, respectively). Milk PRL concentration was significantly increased in chronic mastitis-affected quarters with the highest SCC, and had a positive significant correlation between SCC, as well as between the number of neutrophils present in milk samples. The present findings show that PRL promotes an inflammatory response in bovine mammary epithelial cells via NF-kappa B activation, and suggest a role for PRL in the pathogenesis of chronic mastitis.

From 1994 to 2004, Hill's Pet Nutrition received 4495 canine (65%) and feline (35%) uroliths from Benelux veterinary practitioners. They were sent to the Minnesota Urolith Center, USA for analysis. In 1994, 110 uroliths were analysed - 85% from dogs - and in 2003, 1067 uroliths were analysed - 59% from dogs. During this period, substantial changes were observed in composition. In 1994, 77% of the cats had uroliths composed of struvite, and 12% had uroliths composed of calcium oxalate. In 2003, feline uroliths were composed of 32% struvite, and 61% calcium oxalate. The same evolution was observed in the dogs. In 1994, 51% of canine uroliths were composed of struvite, and 33% of calcium oxalate. In 2003, 40% had struvite uroliths, and 46% had calcium oxalate uroliths. A significant effect of the size, the breed, and the gender were noticed in the dogs. The mean age of uroliths appearance was 7.3 years in the dogs and 7.2 years in the cats. The findings are similar to those previously published in the USA. [less ▲]

The study was carried out at the Mahwa station located in Bututsi natural region in South of Burundi at 1850 m of altitude. The objective of the study was to assess the effects of days in milk, cow's calving age, type of crossbreeding, year and month of lactation, parity on daily milk yield of crossbreds Ayrshire (AY) x Sahiwal (S) x Ankole (A) cows. Milk yields were obtained from 9 cows (S) that have been both milked and suckled during the entire lactation, on 8 cows (M) only milked during the entire lactation and on 150 cows (SM) suckled before and milked after weaning. Data were analyzed using the procedure GLM in SAS for S,M, and SM cows separately. All factors affected significantly daily milk yields (P < 0.001). Least-squares means (LSM) for daily milk yields were highest at the 8th (7.16 +/- 0.07 1), 8th (7.63 +/- 0.35 1), and 7th (7.34 +/- 0.39 1) day in milk for SM, S and M lactations, respectively. The Wood model was able to detect 2 main groups of curve shape: standard for SM and S cows and atypical decreasing for M cows. An important decrease in milk production was observed around the 120th day in SM cows corresponding to the weaning period. Crossbreeding improved milk production and highest yields were observed with 50% to 75% of Ayrshire inheritance (LSM = 5 +/- 0.05 to 5.51 +/- 0.02 1/day). A significant increase was observed from 1977 to 1992 due to the improvement of genetic and management techniques. During this period, LSM raised from 1.26 +/- 0.11 1 to 4.74 +/- 0.03 1 per day for SM cows. Unfortunately, the 1993 civilian war destabilized the managerial techniques and consequently, the milk production decreased in Mahwa station, In all cows, milk production was significantly higher from December to May (LSM - 3.96 +/- 0.03 1/day) during the rainy season than in September (LSM = 3.12 +/- 0.03 1/day) at the end of the dry season.

REASONS FOR PERFORMING STUDY: Stress echocardiography could be a useful diagnostic test in horses suspected to suffer from exercise-induced myocardial dysfunction as a cause of exercise intolerance. OBJECTIVE: To evaluate the effect of treadmill exercise and pharmacological stress test on left ventricular echocardiographic parameters. METHODS: Echocardiography was performed in 2 groups of 5 healthy horses, either immediately after a near-maximal treadmill exercise (Group EXE) or during a pharmacological challenge (Group DOB) consisting of 35 microg/kg atropine, followed by incremental dobutamine infusion rates of 2-6 microg/kg bwt/min for 5 min duration each, which led to a cumulative dobutamine dose of 100 microg/kg. Left ventricular M-mode parameters were compared at rest and at heart rates of 80, 100, 110, 120 130, and 140 beats/min, within each group. RESULTS: In 2 horses of Group EXE, echocardiographic measurements were impossible at 140 and 130 beats/min, as their heart rates dropped too fast in the immediate post exercise period. In the remaining 3 horses image quality was not always satisfactory at heart rates of 130 and 140 beats/min. Systolic left ventricular parameters and fractional shortening measured at 130 and 140 beats/min were significantly different from values obtained at lower heart rates. Horses in Group DOB reached expected heart rates of 80 and 100 beats/min, after the administration of atropine and during a dobutamine infusion rate of 2 microg/kg bwt/min, respectively. Heart rates targets of 110, 120, 130, and 140 beats/min were reached at mean (+/- s.d.) dobutamine infusion rates of 2.8 +/- 0.4, 3.2 +/- 0.4, 4.0 +/- 0.7, 5 +/- 0.7 microg/kg bwt/min, respectively. Systolic left ventricular parameters and fractional shortening at heart rates of 110, 120, 130, and 140 beats/min, were significantly different from values obtained at lower heart rates. CONCLUSION: The pharmacological stress test induced changes in ventricular dimensions at heart rates of 80 to 140 beats/min. Using this test, high quality images can easily be obtained at heart rates of 140 beats/min. Conversely, in post exercise echocardiography, obtaining good quality images at heart rates of 130 and 140 beats/min is difficult, which limits use of the technique in routine clinical settings. POTENTIAL RELEVANCE: Further studies should demonstrate the potential of pharmacological stress test as a diagnostic tool in horses suffering from exercise-induced myocardial dysfunction. [less ▲]

The objective of the present study was to assess the validity of barometric whole-body plethysmography (BWBP), to establish reference values, and to standardise a bronchoprovocative test to investigate airway responsiveness using BWBP in healthy dogs. BWBP measurements were obtained from six healthy beagle dogs using different protocols: (1) during three consecutive periods (3.5 min each) in two morning and two evening sessions; (2) before and after administration of two protocols of sedation; (3) before and after nebulisation of saline and increasing concentrations of carbachol and histamine both in conscious dogs and in dogs under both protocols of sedation. Enhanced pause (PENH) was used as index of bronchoconstriction. Basal BWBP measurements were also obtained in 22 healthy dogs of different breeds, age and weight. No significant influence of either time spent in the chamber or daytime was found for most respiratory variables but a significant dog effect was detected for most variables. A significant body weight effect was found on tidal volume and peak flow values (P < 0.05). Response to carbachol was not reproducible and always associated with side effects. Nebulisation of histamine induced a significant increase in respiratory rate, peak expiratory flow, peak expiratory flow/peak inspiratory flow ratio and PENH (P < 0.05). The response was reproduced in each dog at different concentrations of histamine. Sedation with acepromazine + buprenorphine had little influence on basal measurements and did not change the results of histamine challenge. It was concluded that BWBP is a safe, non invasive and reliable technique of investigation of lung function in dogs which provides new opportunities to characterise respiratory status, to evaluate airway hyperresponsiveness and to assess therapeutic interventions.
