The medical records from 95 cases of coxofemoral luxation in dogs and cats were reviewed. Unilateral craniodorsal luxation was most common, (78.1% of dogs, 72.7% of cats). Trauma from being struck by an automobile was the most frequent cause (59.0%). Treatment was closed (manual) or open (surgical) reduction. The failure rate following single closed reduction was 64.8%. The surgical reduction procedure included capsular repair (capsulorrhaphy) via a craniolateral approach to the hip or via trochanteric osteotomy or gluteal tenotomy. The success rate following reduction via the craniolateral approach was 82%; no failure was recorded with trochanteric transposition, but reluxa-tion followed the single gluteal tenotomy. The Ehmer sling was the most common external fixation and was kept in place an average of 12.5 days. Thirty-three animals were available for follow-up, and no difference was recorded in limb function between the two groups of animals treated by closed vs surgical reduction. Patients with degenerative joint disease at the time of luxation were less likely to be successfully reduced; 64.3% of these animals were eventually treated by femoral head and neck excision. Thirty-eight patients had associated major injuries. Long-term follow-up results were better in those patients with concomitant orthopedic injuries than in those without other injuries.  相似文献

The RNA interference     

KONG Xiang-ping  Lixing W. Reneker 《园艺学报》2004,20(5):900-903

The phenomenon of RNA interference (RNAi) is highly conserved mechanism in the organism evolution. As a immune system, RNAi is a ubiquitous mechanism against invading microorganism in plant and animal cells. Recently, it has been found that RNAi is the process by which double-strand RNA(dsRNA) directs sequence-specific degradation of messenger RNA and the mediations of sequence specific messenger RNA degradation are 21-and 23-nucleotide small interfering RNAs that generate by ribonuclease from endogenous longer dsRNA or by transfectious technics from heterologous dsRNA. Over the past few years, the way in which cells respond to dsRNA by silencing homologous genes has revealed a new regulating paradigm in biology.  相似文献   

The physical appearance of the vulva in ureaplasma infected ewes     

W J McCaughey  H J Ball 《Veterinary research communications》1985,9(2):123-125

The vulvar labia of ewes naturally infected with ureaplasma were significantly more swollen and red than those of uninfected ewes. Similar changes were observed following experimental infection of previously uninfected ewes. These differences, although statistically significant, were not sufficiently marked to be useful in diagnosing infection by clinical examination.  相似文献   

Individual antigens of cattle. Bovine CD2 (BoCD2).     

W C Davis  G S Splitter 《Veterinary immunology and immunopathology》1991,27(1-3):43-50

The data obtained in the workshop provide further evidence that CH128A and IL-A26 and the 12 new mAbs that form a cluster recognise the bovine orthologue of CD2. The mAbs inhibit rosetting with SRBC, stain cells in primary and secondary lymphoid organs in patterns consistent with those obtained in humans with anti-CD2 mAbs, and the 11 IgG mAbs all immunoprecipitate a peptide with a Mr of 58-62 kDa. It is not clear from the studies whether the epitopes defined by the mAbs correspond with the region I and II epitopes present on CD2. None of the data suggest that any of the mAbs recognise the region III (CDD2R) epitope (Peterson and Seed, 1987; Knapp et al., 1989). Further studies are now needed to define the physical and functional relation of the epitopes and establish whether antibody-mediated activation corresponds with that noted in humans. Data reported in one study (Baldwin et al., 1988) with IL-A26 suggest possible differences in the requirements for activation. In addition, further studies are needed to demonstrate how many cell types express BoCD2. In mice, evidence has been presented which shows the mouse orthologue is expressed on some B cells (Yagitta et al., 1989). Studies in cattle have clearly shown CD2 is present on the majority of CD4+ and CD8+ T-cells and a small population of CD4-/CD8- cells (Baldwin et al., 1988; Davis, unpublished observations). Evidence presented in this workshop has shown that some CD2+ cells express a WC2 molecule (Sopp et al., 1991).(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Multifactorial analysis of distance in studies of ecological community structure     

W. J. Krzanowski 《Journal of Agricultural, Biological & Environmental Statistics》2002,7(2):222-232

A framework is described for partitioning the matrix of between-sample distances that forms a starting point for many ecological studies into contributions attributable to different factors in a structured data set. This partitioning enables a series of ordinations to be produced that better enable an insight to be gained into the effects of the factors. More detailed application of the same partitioning provides a decomposition of each factorial effect into single degree-of-freedom contrasts, which enables reasons for observed trends to be investigated. The methods are illustrated by application to data from a study of marine community structure.  相似文献
