The current hypothesis proposed for strangulation of small intestine by a pedunculated lipoma in horses involves movement of the lipoma around the small intestine until it loops through its own pedicle. This mechanism is difficult to demonstrate during surgical correction. The objective was to examine an alternative explanation for strangulation by pedunculated lipomas that is logical and consistent with intraoperative findings by the analysis of the anatomical features of 11 cases of lipoma strangulation in horses. In the proposed hypothesis, the stalk of the lipoma is tensed by the weight of the lipoma alone or by external forces on it from adjacent intestine. This produces a slit-like aperture formed by the stalk and the contiguous mesentery. One or more loops of intestine pass across the lateral edge of the stalk before turning into this aperture, either because of lack of space in the abdominal cavity or through the effects of peristalsis. The weight of the intestine itself causes the loop to ‘fall’ into the aperture and become entrapped. This creates a half-hitch knot in which the loop of intestine uses the lipoma pedicle as a ‘post’ around which it becomes strangulated. It was concluded that the proposed hypothesis differs from the existing one by requiring intestinal movement to create the strangulation, which is more plausible than the current proposal that the strangulation is caused by movement of the lipoma itself. It is also more consistent with surgical findings. 相似文献

Submaxillary gland of mouse: effects of a fraction on tissues of mesodermal origin in vitro 总被引：1，自引：0，他引：1

A macromolecular fraction from mouse salivary glands markedly enhances growth of mesenchymal tissues in vitro. The same fraction causes dedifferentiation of tissues of mesodermal origin, such as muscle and cartilage. Dedifferentiated tissues do not divide but survive in good condition, while controls in the same cultural media undergo regressive changes. 相似文献

Many therapies have been proposed to prevent and treat postoperative ileus (POI) in horses, but to date none is considered fully effective. Various methods have been considered in the prevention of POI in humans too, and among these, gum chewing is gaining a role, reducing time from surgery to first fecal passage and hospitalization time. The aim of the present study is to produce a method to consistently induce horses at chewing without ingesting food and to evaluate its effects on gut sounds in healthy horses. Animals used in this study were 10 adult horses of both genders. A digital phonendoscope was positioned on the right upper flank. A first registration was started and lasted for five consecutive minutes. Then a snaffle bit with toggles was applied to the horse, and a second registration was obtained in the following 15 minutes. Recording sessions were cut into 5-minute subsessions and blindly assessed by two operators that calculated the number of borborygmi per minute in each session. Application of a bit produced consistent mastication and swallowing in all horses for a period of 20 minutes or more. There was a significantly different increase in short (<3 seconds) gut sounds in the first 5 minutes after application of the bit. In conclusion, mastication of a bit consistently caused an increase in gut sounds on the right upper quadrant. Bit chewing can be easily obtained in horses at rest, and further evaluation as an adjunctive element in the management of POI is warranted. 相似文献

As part of annual colony counts in Santa Cruz Province, Argentina, a health survey of rockhopper penguins (Eudyptes chrysocomes) was conducted in 1994. Forty-five birds were examined during handling procedures, and blood and fecal samples were collected for laboratory analysis. All birds appeared to be in good condition. No ecto- or endoparasites were found. Hematology, plasma chemistry, and plasma mineral levels were measured and correlated with the results of bacterial and viral serology. Antibodies against Chlamydia sp., avian adenovirus, avian encephalomyelitis virus, infectious bronchitis virus, avian reovirus, and paramyxovirus-1, -2, and -3 were found. Mean plasma chemistry and mineral values differed between individuals testing positive and negative on serologic tests. There was no serologic evidence of exposure to avian influenza virus, duck viral enteritis, infectious bursal disease, infectious laryngotracheitis, Aspergillus sp., or Salmonella pullorum. Trace amounts of endrin were found in the plasma of one bird, but all other chlorinated pesticide and polychlorinated biphenyl levels were below detectable limits. 相似文献

OBJECTIVE: To compare 3 dorsal techniques for arthrocentesis of the distal interphalangeal joint in horses with regard to ease of performing the technique and to determine the role of operator experience in ease of performing these techniques. DESIGN: Observational study. Sample Population-Forelimbs from 17 equine cadavers and 12 horses (16 joints) undergoing arthrocentesis for therapeutic or diagnostic purposes. PROCEDURES: In both forelimbs from 7 of the equine cadavers, 3 arthrocentesis techniques (dorsal perpendicular, dorsolateral, and dorsal inclined) were performed in random order by a single experienced individual, and number of attempts needed to successfully insert the needle into the joint was recorded. For the forelimbs from the remaining 10 cadavers, veterinary students without experience in arthrocentesis performed each of the 3 arthrocentesis techniques (2 limbs/student) in random order, and number of attempts was recorded. In the clinical patients, arthrocentesis was performed by means of the dorsal inclined technique. RESULTS: For both the experienced individual and the veterinary students, number of attempts needed was significantly lower with the dorsal inclined technique than with the dorsal perpendicular or dorsolateral technique. Arthrocentesis was successful with the dorsal inclined technique in all 16 joints in the clinical patients; synovial fluid was recovered from 14 of the 16 joints. The procedure was well tolerated in all horses, except one that reacted to needle insertion. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that the dorsal inclined technique for arthrocentesis of the distal interphalangeal joint was easier to perform than was the dorsal perpendicular or dorsolateral technique, regardless of experience level of the operator. 相似文献
