A young adult, 28 kg, intact female Siberian husky-mixed breed dog was presented to the Veterinary Medical Teaching Hospital (VMTH) Emergency Service for evaluation of a dysrhythmia and an abnormal cardiac structure. The dog had been adopted from an animal shelter approximately 3 months before presentation. The dog occasionally showed exercise intolerance, and the owners suspected that she had impaired vision. Initial clinical signs appeared 2 days before presentation during strenuous activity—the dog uncharacteristically stopped and lay down while tachypneic. The dog produced dark liquid feces and was lethargic and anorexic overnight. 相似文献

Treatments with prohexadione-calcium led to lowered incidence of fire blight, scab and other diseases in pome fruit trees and other crop plants. In addition to acting as a growth regulator, prohexadione-calcium interferes with flavonoid metabolism and induces the accumulation of the 3-deoxycatechin luteoliflavan in shoots of pome fruit trees. Luteoliflavan does not possess any remarkable antimicrobial activity. Therefore luteoforol, its unstable and highly reactive precursor, has been tested in vitro for its bactericidal and fungicidal activities. Luteoforol was found to be highly active against different strains of Erwinia amylovora, the causal agent of fire blight, and all other bacterial and fungal organisms tested. Phytotoxic effects were also observed in pear plantlets. The results obtained indicate that prohexadione-calcium induces luteoforol as an active principle with non-specific biocidal properties. It is proposed that luteoforol is released upon pathogen attack from its cellular compartment and inhibits further disease development by destroying pathogen cells as well as by inducing a hypersensitive-like reaction in the host plant tissue. This mechanism would be closely analogous to the one known for structurally related phytoalexins in sorghum. 相似文献

Zusammenfassung Die Korrelationsstruktur kultivierterSorghum-Sippen wurde mittels Berechnungen von Koeffizienten der Divergenz der Korrelationen (KDK) und Ähnlichkeitskoeffizienten (ÄK) untersucht. Dafür wurden22 Merkmale an 54 nach dem System vonJakusevkij (1969) 7 Kulturarten zugerechnetenSorghum-Sippen geprüft. Besonders wurden morphologische Merkmale der vegetativen Sphäre und ökologische Merkmale untersucht, die gewöhnlich für dieSorghum-Systematik, die sich auf Merkmale der Organe der generativen Sphäre gründet, keine große Rolle spielen.Nach den Ergebnissen von KDK und ÄK erweist sich der S.durra-Komplex, der deutlich viele Kulturpflanzenmerkmale zeigt, als besonders hoch entwickelt. Ihm sehr ähnlich ist derS. nervosum-Komplex. DerS. guineense-Komplex dagegen steht weit von diesen Artenkomplexen, die sich im Zentrum der Diagramme befinden (Abb. 3 und 4), entfernt. Seine Merkmale entsprechen im Durchschnitt auch mehr dem Wildtyp.Beim Studium der Korrelationsstruktur war es möglich, anhand der von uns gewählten Merkmale manche Artenkomplexe deutlich zu unterscheiden. Es wird festgestellt, daß einige der in neuerer Zeit zu einer Art zusammengefaßten kultiviertenSorghum- Sippen als eigenständige Arten aufgefaßt werden können.

Remarks on some cultivatedSorghum races on the basis of their correlation structure
Summary The correlation structure of cultivatedSorghum races was studied by using the coefficient of divergence of correlations (KDK) and the coefficient of similiarity (ÄK). In 54Sorghum races (table 1), which were grouped into 7 species (table 2) according toJakuevskij (1969),22 characters (table 3) were studied. Above all morphological characters from vegetative organs and ecological characters were tested, which do not play an important role for the systematics ofSorghum, because this is founded on characters from generative organs mainly. The results from KDK (fig. 3) and ÄK (fig. 4) show that theS. durra — complex is highly developed and has many characters of cultivated plants. TheS. nervosum-complex is similar to it. Whereas theS. guineense — complex can be found at the periphery of the diagrams (fig. 3 and 4) far away from the already mentioned complexes, which are located in the centres of the diagrams. The characters of theS. guineense — complex are similar to the wildSorghums mainly.From the study of the correlation structure it was possible to separate some of the species — complexes very clearly by using the above mentioned characters. We can state that some of the cultivatedSorghums, which are now often united into one species, may be regarded as good species.

OBJECTIVE: To determine if screw loosening in triple pelvic osteotomies (TPO) is minimized when screws cranial to the ilial osteotomy had maximal sacral purchase. STUDY DESIGN: Prospective study. ANIMALS: Forty-six dogs with decreased acetabular coverage of the femoral head and minimal degenerative joint changes. METHODS: TPOs were performed where screws cranial to the ilial osteotomy were inserted to maximally engage sacral bone. Data collected were: use of ilial and ischial cerclage wire, screw length, ventrodorsal radiographic sacral width (most caudal aspect), pelvic canal diameter, and sacral penetration of the 3 cranial screws. On all subsequent radiographs, changes in screw position, pelvic canal diameter, and sacral purchase were noted. RESULTS: For 69 TPOs, 414 screws were used. Mean radiographic cranial screw length was 34.54 mm. Combined sacral depth of all 3 screws was 93.3% of sacral width. All osteotomies healed uneventfully. Twenty-four screws (6%) loosened with 12 being in the most cranial positions. Use of ischial or ilial cerclage wires did not statistically influence screw loosening. Pelvic diameter decreased by a mean of 7.79% from postoperative radiographs to the last radiographic recheck. CONCLUSIONS: By sufficiently engaging the sacrum with screws cranial to the ilial osteotomy, implant failures can be avoided and screw loosening minimized when a 6-hole TPO plate is used. CLINICAL RELEVANCE: To minimize screw-loosening in TPO, screws inserted cranial to the ilial osteotomy should be inserted to maximum sacral depth without penetrating the vertebral canal. 相似文献

OBJECTIVE: To characterize the mechanical performance of a veterinary bone anchor under static and cyclic loads. STUDY DESIGN: Mechanical testing study. ANIMALS: Cadaveric canine humeri. METHODS: Humeri (6 pairs) were collected from skeletally mature dogs (mean [+/-SD] age, 17.2+/-2.1 months; weight, 20.8+/-1.5 kg). Bone anchors were inserted in the proximal metaphysis using nylon, and were longitudinally extracted. For the opposite humerus, anchors were subjected to longitudinal cyclic load (50% of the load at failure of their pair) for 1200 cycles then longitudinally loaded to failure. Anchors were then installed in a similar and adjacent area of these 2(nd) humeri with nylon and cyclically tested perpendicular to the axis of anchor insertion (100% of the longitudinal holding power of their pair) for 1200 cycles, then perpendicularly loaded to failure. Paired t-tests were used to compare holding power before and after longitudinal cyclic testing. RESULTS: Longitudinal holding power of the screw-type anchor in the proximal humerus was 385+/-30 N. Anchor pullout was the only mode of failure. Anchors in the paired humeri did not fail after 1200 cycles of 50% longitudinal loading, and post-cycle holding strength was not different (335+/-87 N; P=.32). Perpendicularly loaded anchors did not fail after 1200 cycles of 100% of opposite longitudinal holding strength, and had post-cycle perpendicular holding strengths of 514+/-72 N. Suture breakage was the mode of failure. CLINICAL RELEVANCE: Bone anchor holding strength is dependent on orientation of suture load. Screw-type bone anchor holding strength was not affected by longitudinal cyclic loading, and holding strengths of approximately 385 N can be expected in metaphyseal bone of large-breed mature dogs. Perpendicularly loaded anchors have higher failure loads, and holding strength of approximately 514 N can be expected in metaphyseal bone of the proximal humerus. 相似文献
