Valvular pulmonic stenosis in bullmastiffs     

R. Malik  D. B. Church  G. B. Hunt 《The Journal of small animal practice》1993,34(6):288-292

Six bullmastiffs with congenital heart disease were evaluated over a three-year period. In all the cases the problem was shown to be dysplasia of the pulmonary valve. Five cases were male, one was female. All dogs available to follow-up developed signs of cardiac decompensation. Bullmastiffs must be added to the list of breeds in which valvular pulmonic stenosis is encountered frequently.  相似文献   

Enzyme Immunoassays for the Determination of Ovine LH and FSH   总被引：2，自引：0，他引：2  

GM Peclaris  A Pappa  K Deligiannis  K Koutsotolis 《Reproduction in domestic animals》2003,38(5):367-372

The development of competitive enzyme immunoassays for ovine plasma LH (oLH) and FSH (oFSH) is described. Standards and plasma samples were preincubated with diluted antiserum to oLH or oFSH and the reacted solution (100 μl per well) was transferred to plates previously coated with oLH or oFSH, respectively. The second antibody used was anti‐rabbit IgG horseradish peroxidase. The measuring range was 0.39–50 ng/ml for each hormone and the 50% relative binding sensitivity was 9 ng/ml for oLH. The respective value for oFSH was 3.5 or 34 ng/ml with different hormone and antibody preparations used for the assay. The enzyme immunoassays were used to determine oLH and oFSH levels in plasma from ewes of two breeds during the oestrous cycle. The assays detected the first FSH surge coincident with the LH surge, the second FSH surge about 24 h later and the periodic fluctuations of FSH concentrations during the luteal phase of the oestrous cycle. These enzyme immunoassays are an efficient and economic alternative to the established radioimmunoassays (RIA) for oLH and oFSH.  相似文献   

Effects of heartworm and intestinal parasitic infections on hematology and peripheral lymph node cytology in louisiana dogs     

Gossett KA  Root CR  Cleghorn B  Church GE  Turk JR  Turk MA 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1987,16(4):97-101

Hookworm infected dogs had higher blood basophil counts than hookworm negative dogs. Dogs with occult heartworm infection (i.e., without microfilaremia) had higher blood neutrophil counts than heartworm negative dogs. The percentage of eosinophils in peripheral lymph nodes was higher in heartworm infected, microfilaremic dogs than in both occult infected dogs and heartworm negative dogs. Heartworm or intestinal parasitic infection had no other significant effects on hematologic parameters or peripheral lymph node cytology.  相似文献

Effects of phenobarbitone on serum biochemical tests in dogs     

Foster SF  Church DB  Watson AD 《Australian veterinary journal》2000,78(1):23-26

OBJECTIVES: To investigate effects of phenobarbitone on serum activities of alanine aminotransferase, alkaline phosphatase and gamma-glutamyl transferase and concentrations of bilirubin, albumin, cholesterol and total protein in dogs. ANIMALS: Ten crossbreed experimental dogs and 10 client-owned dogs of mixed breeds treated chronically with phenobarbitone to control seizures. PROCEDURES: Experimental dogs were allocated to treatment (6 mg/kg oral phenobarbitone, n = 6) and control (no treatment, n = 4) groups in which serum biochemical tests were performed at intervals during a 3-month period. Biochemical tests were performed once on the 10 epileptic dogs. RESULTS: Phenobarbitone caused increased serum alkaline phosphatase activity but did not affect gamma-glutamyl transferase activity or bilirubin, cholesterol, albumin and total protein concentrations. Phenobarbitone had minimal effect on alanine aminotransferase activity. CONCLUSIONS: Individual dogs treated with phenobarbitone may have small increases in serum alanine aminotransferase activity and variable increases in alkaline phosphatase activity but are unlikely to have alterations in gamma-glutamyl transferase activity or bilirubin, cholesterol, albumin or total protein concentrations.  相似文献

The Control of Reactive Oxygen Species Influences Porcine Oocyte In Vitro Maturation          下载免费PDF全文

GM Alvarez  SA Morado  MP Soto  GC Dalvit  PD Cetica 《Reproduction in domestic animals》2015,50(2):200-205

The aim of this study was to examine the effect of varying intracellular reactive oxygen species (ROS) levels during oocyte in vitro maturation with enzymatic ROS production systems (xanthine + xanthine oxidase or xanthine + xanthine oxidase + catalase), scavenger systems (catalase or superoxide dismutase + catalase) or cysteine on porcine oocyte maturation. Oocyte ROS levels showed an increase when H₂O₂ or O₂?^‐ production systems were added to the culture medium (p < 0.05). On the other hand, the presence of ROS scavengers in the maturation medium did not modify oocyte ROS levels compared with the control after 48 h of maturation, but the addition of cysteine induced a decrease in oocyte ROS levels (p < 0.05). The ROS production systems used in this work did not modified the percentage of oocyte nuclear maturation, but increased the decondensation of sperm head (p < 0.05) and decreased the pronuclear formation (p < 0.05). In turn, the addition of O₂?^‐ and H₂O₂ scavenging systems during in vitro maturation did not modify the percentage of oocytes reaching metaphase II nor the oocytes with decondensed sperm head or pronuclei after fertilization. However, both parameters increased in the presence of cysteine (p < 0.05). The exogenous generation of O₂?^‐ and H₂O₂ during oocyte in vitro maturation would not affect nuclear maturation or later sperm penetration, but most of the spermatozoa cannot progress to form the pronuclei after fusion with the oocyte. The decrease in endogenous ROS levels by the addition of cysteine would improve pronuclear formation after sperm penetration.  相似文献
