The influence of fasting on blood glucose,triglycerides, cholesterol,and alkaline phosphatase in rats     

Waner T  Nyska A 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1994,23(3):78-80

Serum concentrations of glucose, cholesterol, triglycerides, and serum alkaline phosphatase activity were measured over different periods of time of food deprivation in male rats. Thirty percent of non-fasted rat's sera was found to be lipemic. At 16 hours of fasting, glucose levels dropped by 30% compared to the level of the non-fasting control group, and remained at a relatively constant level for up to 48 hours of fasting. Triglyceride concentrations decreased at 16 hours after fasting. Serum cholesterol levels were not changed at any of the fasting periods compared to the non-fasted control group. Alkaline phosphatase activity was decreased at 8 hours of fasting, with further declines in activity of the serum enzyme seen at 16, 24, and 48 hours of fasting. It was concluded that at 16 to 18 hours fasting, a non-absorptive state had been reached in male rats.  相似文献   

Noninferiority trial investigating the efficacy of a nonantibiotic intramammary therapy in the treatment of mild‐to‐moderate clinical mastitis in dairy cows with longer lasting udder diseases          下载免费PDF全文

A nonblinded, positively controlled, noninferiority trial was conducted to evaluate the efficacy of an alternative, nonantibiotic therapy with Masti Veyxym^® to reduce ineffective antibiotic usage in the treatment of nonsevere clinical mastitis (CM) in cows with longer lasting udder diseases. The solely intramammary treatment with Masti Veyxym^® (three applications, 12 hr apart) and the combined treatment with Masti Veyxym^® and antibiotics as usual on the farm according to label of the respective product were compared with the reference treatment of solely antibiotic therapy. The matched field study was conducted on eight free‐stall dairy farms located in Eastern Germany. Cases of mild‐to‐moderate CM in cows with longer lasting high somatic cell counts in preceding dairy herd improvement test days and with previous CM cases in current lactation were randomly allocated to one of the three treatment groups. A foremilk sample of the affected quarter was taken before treatment and again approximately 14 days and 21 days after the end of therapy for cyto‐bacteriological examination. Primary outcomes were clinical cure (CC) and no CM recurrence within 60 days after the end of treatment (no R60). Bacteriological cure (BC) and quarter somatic cell count (QSCC) cure were chosen as secondary outcomes although low probabilities of BC and QSCC cure for selected cows were expected. The study resulted in the following findings: the pathogens mostly cultured from pretreatment samples were Streptococcus uberis, followed by Staphylococcus aureus and coagulase‐negative staphylococci. There were no significant differences between the two test treatments in comparison with the reference treatment regarding all outcome variables. The sole therapy with Masti Veyxym^® resulted in a numerically lower likelihood of BC without significant differences to the reference treatment. The combined therapy group showed a numerically higher nonrecurrence rate than the two other treatment groups and noninferiority compared to the reference treatment was proven. Having regard to the selection criteria of cows in this study, the findings indicated that sole treatment with Masti Veyxym^® in nonsevere CM cases may constitute an alternative therapy to reduce antibiotics. However, noninferiority evaluations were mostly inconclusive. Further investigations with a larger sample size are required to confirm the results and to make a clear statement on noninferiority.  相似文献   

Investigation of Clinical Medicine for Treating Cows Endometritis in Baotou Area     

JIA Zhi-li  LI Pei-feng 《中国畜牧兽医》2016,43(1):261-266

In 4 dairy farms located in Baotou area, clinical medicine investigation and drug resistance of pathogenic bacteria were conducted, and then curative effects of different treatment methods were analyzed.Epidemic materials were collected from diary cows infected by endometritis, from which pathogenic bacteria were isolated using conventional microbiology technologies.Broth microdilution method was used to detect the sensitivity and resistance of pathogenic bacteria to antibiotics commonly used in clinic.On this basis, the sensitive drugs were used to treat mastitis or endometritis, the clinical curative effect of traditional treatment group was compared with that of therapeutic test group.The result of traditional treatment group showed 13 antibiotics were used to treat 160 cases of endometritis, florfenicol was most effective, penicillin was most ineffective.The results of therapeutic test group showed that Staphylococcus aureus, Escherichia coli and Streptococcus were the main pathogenic bacteria of endometritis, which were sensitive to gentamicin and cefalotin, etc.The results of statistical analysis showed that the curative effect of therapeutic test group was extremely significantly different from that of traditional treatment group(P<0.01).Sensitive drugs screened by drug sensitive test could be used to target therapy, and obtain satisfied curative effect.Moreover, this approach could avoid antibiotic abuse.  相似文献

基层常见猪传染性腹泻病的临床诊断与防控对策     

杨小金  殷玉武 《金陵科技学院学报》2014,(3)

猪传染性腹泻病是猪的常见多发病。基于受基层单位病原检测技术的条件限制,一旦发生传染性腹泻病,基层兽医通常依据临床症状做出初步诊断与治疗,如果临床经验稍有不足,误诊、误治或延误诊治的现象时有发生。为此梳理出了常见的12种猪传染性腹泻病临床诊断要点与综合防治措施,以防止其重大疾病的发生。  相似文献
