The effects of surgical and nonsurgical therapy on the development of osteoarthritis were compared in 12 dogs with bilateral medial patellar luxation and unilateral surgical repair. Evaluations included severity of lameness and patellar luxation, ligamentous stability, range of motion, and radiographic evidence of osteoarthritis before surgery and at a mean of 33 months after surgery. Stifles without surgical treatment served as controls for the contralateral stifles with surgery. All stifles treated surgically had reduced patellofemoral joints, normal range of motion, and improved limb use. Osteoarthritis progressed significantly and comparably in both groups of stifles. Progression of osteoarthritis was not correlated with luxation grade, body weight, or interval from surgery to follow-up. Age at surgery was correlated positively with severity of osteoarthritis in the stifles treated surgically.  相似文献   

The in vitro sensitivity of some species of Chlorophyceae to a selected range of herbicides   总被引：1，自引：0，他引：1  

D. ROY CULLIMOKE 《Weed Research》1975,15(6):401-406

A survey was undertaken to establish the sensitivity of seventeen algal strains belonging to the Chlorophyceae to a selected range of herbicides up to a concentration maximum of 10 ppm under in vitro conditions. The herbicides were found to vary considerably in their toxicity to algae and a sequence was established based upon the magnitude of this toxicity: diuron > bromacil > paraquat> monuron> diquat> linuron> 2, 4-DB >barban> dicamba, dichlobenil, dalapon, picloram> bromoxynil, 2,3,6-TBA > 2.4-DP. 2,4,5-T and EPTAM. Of the algae, the most sensitive genera were Hormidium and Haematococcus, and the strain most sensitive to a wide range of herbicides was Hormidium barlowi (strain 335/la).  相似文献   

Corticocancellous Bone Biopsy from the 12th Rib of Standing Horses     

MARTHA M. MISHEFF DVM    SUSAN M. STOVER DVM  PhD  Diplomate ACVS  ROY R. POOL DVM  PhD 《Veterinary surgery : VS》1992,21(2):133-138

Unicortical corticocancellous bone biopsy specimens 4.5 mm and 6.5 mm in diameter were obtained without long-term complications from the 12th rib in eight standing horses. However, the bone specimens were unsuitable for histologic or histomorphometric evaluation. In in vitro comparisons of biopsy specimens 6.5 mm and 12 mm in diameter, and of unicortical and transcortical biopsy specimens, 12 mm transcortical specimens yielded the most cancellous bone. Transcortical bone biopsy specimens 12 mm in diameter were obtained from eight horses by using power-assisted trephination. The surgical procedure was well tolerated, but some degree of pneumothorax in all horses was treated by aspiration of air from the thorax. Long-term complications were not observed.  相似文献   

Osteochondrosis of the Lateral Trochlear Ridge of the Talus in Seven Rottweiler Dogs     

ERIK R. WISNER DVM    CLIFFORD R. BERRY DVM    JOE P. MORGAN DVM  VetMedDr  Diplomate ACVR    ROY R. POOL DVM  PhD    ALIDA P. WIND DVM  PHILIP B. VASSEUR DVM  Diplomate ACVS 《Veterinary surgery : VS》1990,19(6):435-439

Eleven lesions of osteochondrosis in the lateral trochlear ridge of the talus were diagnosed in seven young Rottweiler dogs. Diagnosis was based on clinical and radiographic evaluations. Defects in the lateral trochlear ridge and osteochondral fragments arising from the dorsal and proximal margins of the ridge were visible radiographically. The dorsal 45 degrees lateral-plantaromedial oblique (D45 degrees L-P1MO) projection was the most useful in identifying the lesions. Exploratory arthrotomies were performed in six affected tarsi. In three cases, histologic examination revealed mineralized osteochondral fragments consistent with a diagnosis of osteochondrosis.  相似文献   

EPPO certification scheme for fruit trees,including almond 1     

A. S. ROY 《EPPO Bulletin》1997,27(4):571-579

For approximately 10 years, EPPO has been working on the development of certification schemes for fruit crops. The production of healthy planting material is an effective tool to ensure that plants moving in trade can be certified free from certain dangerous pests, and also to protect national crop production. In 1981, a first scheme giving the basic principles for the production of virus-free fruit trees and rootstocks was produced and approved by EPPO Council. Later, an EPPO Panel on certification of pathogen-tested fruit crops was created in order to expand the original outline scheme, and in particular to develop technical details of testing procedures. The first part, containing general requirements and explaining how plant material of known filiation passes through several categories of propagation (nuclear stock, propagation stock, certified stock), was published in 1991. It was followed in 1992 by technical appendices which gave details on viruses, virus testing, nematological analysis, thermotherapy, in vitro techniques, etc. The principles of this scheme are presented specifically in relation to almond. At present, the EPPO scheme covers the production of healthy planting material (varieties, rootstocks, seeds) of fruit trees in general, including Malus, Pyrus, Cydonia, Prunus and Juglans regia, but it must be noted that it is currently under revision, in particular to update the technical appendices and to divide it into four separate schemes for apples, pears, cherries and other Prunus. Finally, the fruit-tree scheme is part of a wider programme, covering also grapevine, Ribes, Rubus, strawberry, citrus, Vaccinium, olive, hop and hazelnut.  相似文献   

The effect of non‐marine HUFA supplementation with fish oil removal on growth and survival of the Pacific white shrimp,Litopenaeus vannamei     

T.M. SAMOCHA  D.A. DAVIS  L.A. ROY  B. CARPENTER  R.A. BULLIS 《Aquaculture Nutrition》2011,17(5):518-525

The use of non‐marine arachidonic acid (ArA) and docosahexaenoic acid (DHA) as highly unsaturated fatty acid (HUFA) enrichments was evaluated as complete replacements for marine fish oil in practical diets formulated with solvent‐extracted soybean meal (SESM). Litopenaeus vannamei juveniles (0.59 g) were reared over 84 days in an outdoor tank system with no water discharge. Fishmeal was replaced with SESM, while fish oil was replaced with HUFA‐rich algal cells, alternative oil and/or fermentation products. Spray‐dried Schizochytrium algal cells (Schizomeal‐Hi DHA) served as the DHA enrichment source. Oil extracted from Mortierella sp. was used as the ArA enrichment (AquaGrow^® ArA). DHA and ArA sources (Advanced BioNutrition Corp., Columbia, MD, USA) were non‐marine products obtained from a commercial supplier. Five diets were formulated with ArA inclusion levels of 0, 0.65, 1.3, 2.6 and 5.2 g kg^?1. In addition, one diet was formulated to be DHA deficient and another was formulated with menhaden fish oil (control). Different inclusion levels of non‐marine ArA had no effect on survival or growth. Shrimp fed the non‐marine HUFA‐supplemented diets had lower average weight compared to shrimp offered the diet containing fish oil. No differences were detected in average weights of shrimp offered the ArA‐deficient and ArA‐supplemented diets.  相似文献

Effect of lameness (hoof disorders) on productivity of Karan Fries crossbred cows     

Yajuvendra SINGH  Surender Singh LATHWAL  Atish Kumar CHAKRAVARTY  Ashok Kumar GUPTA  Tushar Kumar MOHANTY  Thiruvothur Venkatesan RAJA  Roshan Lal DANGI  Biplob Kumer ROY 《Animal Science Journal》2011,82(1):169-174

In present study production performance of 96 lame cows was compared with 67 healthy cows. No significant effect of parity and year of calving on milk yield were observed but the effect of season of calving was significant (P < 0.01). Effect of lameness on milk yield at the second, third and fourth months and 305 days was highly significant (P < 0.01), and was also significant (P < 0.05) on lactation yield of the fifth and tenth months. The effect of lameness on monthly and 305‐day milk yield was significant (P < 0.01) only for those cows diagnosed lame before calving and during the first month of lactation. The differences in mean monthly yield were highly significant (P < 0.01) at the second, third and fourth months; and significant (P < 0.05) in the first and fifth months. The loss in the first lactation month of cows which were diagnosed as lame in the second month, was found to be significant (P < 0.05). Thus the yield of the month previous to the diagnosis (sub‐clinical stage) was also affected. A significant (P < 0.01) total loss of 498.95 kg of milk yield was observed during a period of 305 days.  相似文献   

Quasi-thermodynamic basis of competitive-adsorption coefficients for anionic mixtures in soils     

W. R. ROY  J. J. HASSETT  R. A. GRIFFIN 《European Journal of Soil Science》1989,40(1):9-15

Equilibrium competitive-adsorption coefficients derived from the application of the multi-component Freundlich-type Sheindorf-Rebhun-Sheintuch (SRS) equation appeared to have a soil-specific, quasi-thermodynamic basis. Using three soils, single-solute adsorption isotherms at 288, 298, and 308 K were constructed with arsenate, phosphate, and molybdate. A Clausius-Clapeyron-type equation was used to estimate apparent isosteric heats of adsorption values ( q _iso). The adsorption of the three anions was characterized by different q _iso values, and was generally in the order of H₂PO₄->H₂AsO₄->MoO₄^2-. The magnitudes of the SRS competitive coefficients derived from binary-solute mixtures were in agreement with the distributions of the heats of adsorption of the individual anion-soil systems. Higher competitive coefficients, indicating the preferential adsorption of solute i in a binary-solute mixture containing solutes i and j, tended to associate with higher q _iso values for solute i relative to solute j. However, the q _iso values for the adsorption of molybdate by one soil underestimated the extent of competitive interactions between arsenate and molybdate.  相似文献
