BackgroundMinimally invasive surgery (MIS) technique of sacroiliac luxation in toy breed dogs using cannulated screws has not been described.ObjectivesThe purpose of this study was to evaluate the effectiveness of pelvic canal recovery, the reproducibility of successful surgery outcomes, and the acceptable difficulty of the procedure in MIS of sacroiliac luxation in toy breed dogs.MethodsMIS using 2.3-mm cannulated screws was demonstrated in 12 toy breed dog cadavers with sacroiliac luxation artificially induced. Pre and postoperative radiographs were used to evaluate the pelvic canal diameter ratio (PCDR), hemipelvic canal width ratio (HCWR), and reduction rate. Dorsoventral angle (DVA) and craniocaudal angle (CCA) of the inserted screw were obtained postoperative computed tomographic scan.ResultsThe statistically significant difference between the mean pre and postoperative PCDR was found (1.10 ± 0.12 and 1.26 ± 0.11, respectively; p = 0.002), and the mean HCWR close to 1.0 meaning symmetric pelvis also was obtained (0.97 ± 0.07). The mean DVA and CCA were 2.26° ± 1.33° and 2.60° ± 1.86°, respectively.ConclusionsMIS of sacroiliac luxation using 2.3-mm cannulated screws is applicable to toy breed dogs with acceptable difficulty. 相似文献
Insects killed by entomopathogenic nematodes (EPN) represent a resource with which soil arthropods can interact. These interactions can be positive for EPN (e.g., arthropods serve as parasitic or phoretic hosts) or negative (e.g., EPN serve as prey). Plant diversity and soil disturbance may influence these interactions. We investigated the effects of maize and flower strip habitats on microarthropod abundance and community composition in soil surrounding greater wax moth larvae, Galleria mellonella, infected with the EPN Steinernema carpocapsae (Sc). In the first year of the experiment (2005), we compared microarthropod communities responding to burial of Sc-killed insects with a control (no soil disturbance). In 2006, we added two control treatments: burial of freezer-killed insects and sham burial. Soil samples (including G. mellonella) were collected 2 and 20 days (2005) or 2 and 12 days (2006) after application. In 2005, arthropod abundance and community composition were similar between maize and flower strip habitats. In 2006, we detected more arthropods in the maize than the flower strips. In both years, community composition differed between treatments providing resources (Sc-killed and freezer-killed insects) and those without (sham burial and no disturbance), with the greatest difference on the final sampling date. Soil surrounding Sc-killed and freezer-killed insects contained more dipterans, acarid mites, staphylinid beetles, onychiurid and entomobryid collembolans, and immature and male mesostigmatid mites than soil at sham burial and no disturbance sites. Most of these taxa are capable of nematophagy; however, EPN relative abundance was not associated with arthropod community composition. 相似文献
A total body irradiation (TBI) protocol was developed to support a bone marrow transplant (BMT) program for the treatment of canine hematologic malignancies. The purpose of this prospective study is to describe implementation of the protocol and resultant dosimetry. Nongraphic manual treatment planning using 6 MV photons, isocentric delivery, 40 × 40 cm field size, wall‐mounted lasers to verify positioning, a lucite beam spoiler (without use of bolus material), a dose rate of 8.75 cGy/min at patient isocenter, and a source‐to‐axis distance of 338 cm were used for TBI. A monitor unit calculation formula was derived using ion chamber measurements and a solid water phantom. Five thermoluminescent dosimeters (TLDs) were used at various anatomic locations in each of four cadaver dogs, to verify fidelity of the monitor unit formula prior to clinical implementation. In vivo dosimetric data were then collected with five TLDs at various anatomic locations in six patients treated with TBI. A total dose of 10 Gy divided into two 5 Gy fractions was delivered approximately 16 h apart, immediately followed by autologous stem cell transplant. The mean difference between prescribed and delivered doses ranged from 99% to 109% for various sites in cadavers, and from 83% to 121% in clinical patients. The mean total body dose in cadavers and clinical patients when whole body dose was estimated by averaging doses measured by variably placed TLDs ranged from 98% to 108% and 93% to 102% of the prescribed dose, respectively, which was considered acceptable. This protocol could be used for institutional implementation of TBI. 相似文献
