Intra-Articular Replacement of Bovine Cranial Cruciate Ligaments with an Autogenous Fascial Graft     

WILLIAM H. CRAWFORD MVSc  DVM  BSA  BApSc  DiplomateACVs 《Veterinary surgery : VS》1990,19(5):380-388

Transected cranial cruciate ligaments in nine Holstein heifers were replaced with an autograft harvested from fascia on the medial surface of the gluteobiceps muscle and a connected segment of the lateral patellar ligament. There was minimal lameness at month 1, and all animals were sound by month 2. There was no evidence of degenerative joint disease in any stifles examined at necropsy on days 90, 120, or 365. Augmented healing of the severed cranial cruciate ligaments occurred in several animals. The mean failure strength of the cranial cruciate ligament replacements was 29.7% of the failure strength of the contralateral normal cranial cruciate ligament in four heifers. The technique was successful in eight of 13 bulls and cows with ruptured cranial cruciate ligaments. Animals treated successfully had significantly lower body weights than those with unsuccessful outcomes.  相似文献   

Productivity and Sustainability of Cotton (Gossypium hirsutum L.)–Wheat (Triticum aestivum L.) Cropping System as Influenced by Prilled Urea, Farmyard Manure and Azotobacter

Field experiments were conducted at Indian Agricultural Research Institute, New Delhi, during 2001–2002 and 2002–2003, to study the effect of inorganic, organic and Azotobacter combined sources of N on cotton (Gossypium hirsutum L.) and their residual effect on succeeding wheat (Triticum aestivum L.) crop. The results indicated considerable increase in yield attributes and mean seed cotton yield (2.33 Mg ha^?1) with the combined application of 30 kg N and farmyard manure (FYM) at 12 Mg ha^?1 along with Azotobacter (M₄). The treatment in cotton that included FYM, especially when fertilizer N was also applied could either improve or maintain the soil fertility status in terms of available N, P and K. Distinct increase in yield attributes and grain yield of wheat was observed with the residual effect of integrated application of 30 kg N ha^?1 + FYM at 12 Mg ha^?1 + Azotobacter. Direct application of 120 kg N ha^?1 resulted 67.4 and 17.7 % increase in mean grain yield of wheat over no N and 60 kg N ha^?1, respectively. Integrated application of organic and inorganic fertilizer is therefore, recommended for higher productivity and sustainability of the cotton–wheat system.  相似文献   

ENLARGING BILATERAL FEMORAL CONDYLAR BONE CYSTS WITHOUT SCINTIGRAPHIC UPTAKE IN A YEARLING FOAL     

K.R.E. Squire  MVSc  MSc  PhD  J.F. Fessler  DVM  MS  H.D. Cantwell  DVM  MS  W.R. Widmer  DVM  MS 《Veterinary radiology & ultrasound》1992,33(2):109-113

Bilateral subchondral bone cysts of the femoral condyles were diagnosed by conventional radiography in a 14 month old Appaloosa colt. Surgical debridement was performed, and over the next 18 months the appearance of the cysts was evaluated with radiography and bone scintigraphy. On the preoperative scintigrams, increased radiopharmaceutical uptake was associated with the cysts. Despite continued radiographic enlargement, the cysts did not demonstrate increased radiopharmaceutical uptake post-operatively.  相似文献   

A Gis-derived integrated moisture index to predict forest composition and productivity of Ohio forests (U.S.A.)   总被引：9，自引：0，他引：9

A geographic information system (GIS) approach was used in conjunction with forest-plot data to develop an integrated moisture index (IMI), which was then used to predict forest productivity (site index) and species composition for forests in Ohio. In this region, typical of eastern hardwoods across the Midwest and southern Appalachians, topographic aspect and position (rather than elevation) change drastically at the fine scale and strongly influence many ecological functions. Elevational contours, soil series mapping units, and plot locations were digitized for the Vinton Furnace Experimental Forest in southeastern Ohio and gridded to 7.5-m cells for GIS modeling. Several landscape features (a slope-aspect shading index, cumulative flow of water downslope, curvature of the landscape, and water-holding capacity of the soil) were used to create the IMI, which was then statistically analyzed with site-index values and composition data for plots. On the basis of IMI values for forest land harvested in the past 30 years, we estimated oak site index and the percentage composition of two major species groups in the region: oak (Quercus spp.), and yellow poplar (Liriodendron tulipifera) plus black cherry (Prunus serotina). The derived statistical relationships were then applied in the GIS to create maps of site index and composition, and verified with independent data. The maps show the oaks will dominate on dry, ridge top positions (i.e., low site index), while the yellow poplar and black cherry will predominate on mesic sites. Digital elevation models with coarser resolution (1:24K, 1:100K, 1:250K) also were tested in the same manner. We had generally good success for 1:24K, moderate success for 1:100K, but no success for 1:250K data. This simple and portable approach has the advantage of using readily available GIS information which is time-invariant and requires no fieldwork. The IMI can be used to better manage forest resources where moisture is limiting and to predict how the resource will change under various forms of ecosystem management.  相似文献   

ULTRASONOGRAPHIC AND CLINICOPATHOLOGIC FINDINGS IN 21 DOGS WITH INTESTINAL ADENOCARCINOMA     

Melissa C.  Paoloni  DVM  Dominique G.  Penninck  DVM  DVSc  Antony S.  Moore  BVSc  MVSc 《Veterinary radiology & ultrasound》2002,43(6):562-567

In a retrospective study of 21 dogs with intestinal adenocarcinoma, the signalment, clinical presentation, laboratory findings, ultrasonographic features, treatment, and outcome were reviewed. Anorexia (n = 16), vomiting (n = 15), diarrhea (n = 10), and weight loss (n = 9) were the most common clinical signs reported. Ultrasonographic features that were evaluated included location, length, wall thickness, echogenicity, regional motility, layering, regional lymphadenopathy, and fluid accumulation proximal to the lesion site. All lesions were transmural and associated with complete loss of wall layering. Maximum wall thickening at the lesion site ranged from 7 to 17 mm (median 12 mm, mean 11.9 mm). Most of the dogs had a lesion measuring from 23 to 63 mm in length, (median 40 mm, mean 42 mm). Most intestinal lesions were poorly echogenic and had an irregular lumen. Fluid accumulation proximal to the lesion site was identified in 17 of 21 dogs, and in 13 of 17 dogs the fluid accumulation was considered moderate to severe. Regional lymphadenopathy and/or nodular mesentery/omentum were noted in 12 of 21 dogs. The tumor was located in small intestine for 15 dogs and in the colon for the remaining 6 dogs. Fifteen dogs were treated by surgical resection of the intestinal mass. Their median survival time was 233 days. Only gender appeared to influence survival. Female dogs lived a median of 28 days, whereas male dogs lived a median of 272 days.  相似文献   

Partial Carpal Arthrodesis for Third Degree Carpal Sprains: A Review of 45 Carpi     

R. L. WILLER DVM    K. A. JOHNSON MVSc  PhD  FACVSc  DiplomateACVs    T. M. TURNER DVM  D. L. PIERMATTEI DVM  PhD  DiplomateACVs 《Veterinary surgery : VS》1990,19(5):334-340

The efficacy of partial carpal arthrodesis was evaluated retrospectively in 39 dogs (45 carpi) with severe sprains of the middle carpal joints, the carpometacarpal joints, or both. The carpometacarpal joint was the most frequently injured joint. Jumping or falling from heights was the cause of injury in 49% of these animals. Of the 25 owners who responded to a mailed questionnaire (mean follow-up, 32 months), all stated their animal had improved or greatly improved after partial carpal arthrodesis and all were pleased or very pleased with the final surgical result. Hyperextension persisted in 11% of the cases and degenerative joint disease of the antebrachiocarpal joint was present in 15.5% of the cases. No dogs with partial carpal arthrodesis required panarthrodesis at a later date.  相似文献   

Effects of Epidural Ketamine–Xylazine Combination on the Clinicophysiological and Haematobiochemical Parameters of Uraemic and Healthy Goats     

Singh K  Kinjavdekar P  Amarpal  Aithal HP  Gopinathan A  Singh GR  Pawde AM  Pratap K 《Veterinary research communications》2007,31(2):133-142

Xylazine–ketamine combination was evaluated for its efficacy and safety after epidural administration in uraemic and healthy goats. The combination (xylazine 0.025 mg/kg and ketamine 2.5 mg/kg) was administered to uraemic (n = 6) and healthy (n = 6) animals in the lumbosacral epidural space. The combination was evaluated in terms of clinical, physiological, haematological and biochemical parameters. The onset of analgesia was faster in healthy animals than in uraemic animals. Xylazine and ketamine produced complete analgesia of tail, perineum, inguinal and thigh regions in all animals of both groups. However, healthy animals showed longer duration of complete analgesia than did uraemic animals. Greater ataxia was recorded in healthy animals than in uraemic animals. The heart rate showed a significant decrease in both groups; however, respiratory rate and rectal temperature did not show any significant changes. Haemoglobin, packed cell volume and total leukocyte count decreased non-significantly in both groups. Total leukocyte count was significantly higher in uraemic animals. A significantly higher value of urea nitrogen and creatinine was recorded in uraemic animals. The blood electrolytes (Na⁺, K⁺ and Cl⁻) and blood gases (P o ₂ and P co ₂) did not show any significant changes in both groups; however, base excess was significantly higher in uraemic animals. The effects produced by the combination on different systems were transient and values normal as the effect of the drugs wore off. The results suggest that the combination when used epidurally in uraemic goats produced effective and safe surgical analgesia.  相似文献

Effects of SO2 exposure on carbohydrate contents,phytomass and caloric values of wheat plants     

B. J. Prasad  D. N. Rao 《Water, air, and soil pollution》1981,16(3):287-291

This paper reports the results of wheat plants exposed to SO₂. The SO₂-treated and control plant samples were periodically analyzed with respect to their carbohydrate content, caloric values, phytomass accumulations and net primary productivity. An initial increase, but later decrease in all these parameters was recorded in SO₂-treated plants. These effects in wheat plants have been interpreted in terms of energy budget of plants under SO₂-stress condition.  相似文献
