Foxtail-induced ulcerative stomatitis outbreak in a Missouri stable.     

S E Turnquist  E N Ostlund  J M Kreeger  J R Turk 《Journal of veterinary diagnostic investigation》2001,13(3):238-240

Twenty of 25 horses in a well-managed Missouri boarding stable were diagnosed with gingivitis/stomatitis. Gross examination of the affected horses revealed varying degrees of gingivitis ranging from mild periodontal swelling to marked swelling and erythema with ulceration and hemorrhage. Fine hair-like material was embedded within the intensely affected areas. Gingival biopsies from 4 affected horses contained pyogranulomatous inflammation with, in some cases, numerous eosinophils and several grass awns in cross and longitudinal section. Numerous foxtail seed heads were identified in hay samples. Examination of the records revealed that all of the affected horses had been fed the suspect hay, with the exception of 1 horse. Although not deliberately fed the suspect hay, this horse did have access to the hay when turned out into the exercise paddock. The lesions resolved following a change in hay source.  相似文献   

Effects of heartworm and intestinal parasitic infections on hematology and peripheral lymph node cytology in louisiana dogs     

Gossett KA  Root CR  Cleghorn B  Church GE  Turk JR  Turk MA 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1987,16(4):97-101

Hookworm infected dogs had higher blood basophil counts than hookworm negative dogs. Dogs with occult heartworm infection (i.e., without microfilaremia) had higher blood neutrophil counts than heartworm negative dogs. The percentage of eosinophils in peripheral lymph nodes was higher in heartworm infected, microfilaremic dogs than in both occult infected dogs and heartworm negative dogs. Heartworm or intestinal parasitic infection had no other significant effects on hematologic parameters or peripheral lymph node cytology.  相似文献

Noninvasive monitoring of doxorubicin cardiotoxicity: a pilot study of two dogs

The cardiotoxicity of anthracycline anticancer agents, most notably doxorubicin, limits their use in treating a wide variety of cancers. Currently available methods for assessment of anthracycline‐induced cardiotoxicity (AIC) often lack specificity and sensitivity. The purpose of this pilot investigation was to determine noninvasive diagnostic methods that are predictive for AIC. Two mongrel dogs were anesthetized for injection of doxorubicin (22.5 mg) directly into the left coronary artery. Doxorubicin injection was repeated 2 weeks later. Dogs were followed for 12 weeks or until heart failure was documented. Dogs were monitored before and at serial time points after doxorubicin using echocardiography and signal‐averaged electrocardiography as well as ambulatory ECG monitoring. Blood was also collected for measurement of cardiac troponin I and T concentrations. Doxorubicin was readministered at 6 and 12 weeks after the second injection, as interim data analysis did not reveal adequate evidence of cardiomyopathy. Dog‐1 appeared to be more sensitive than Dog‐2 to AIC based upon gradual changes in variables of cardiac function and earlier time to failure (113 days). In contrast, Dog‐2 had inconsistent changes in cardiac function and a longer time to failure (139 days). Dog‐1 also had greater peak plasma cardiac troponin I levels (17.96 ng/ml) as compared to peak levels in Dog‐2 (4.08 ng/ml). In addition, Dog‐1 had increased ventricular extrasystolic contractions (VE)(0/day at baseline, 443/day one week prior to death), whereas dog‐2 showed very few VE's throughout. Spectral analysis of ECG data also revealed a significant decrease over time in total spectral power in Dog‐1 from 37,148 at baseline to 603 msec²/Hz one week prior to death, indicating decreased parasympathetic tone. Endomyocardial biopsies revealed minor changes despite significant clinical abnormalities. These data indicate differences in susceptibility to AIC between Dog‐1 and Dog‐2, and suggest a role for these noninvasive measures in monitoring the heart during chemotherapy.  相似文献

Pilot-scale production of mysid shrimp in a static water system     

Pedro M. Domingues  Philip E. Turk  Jose P. Andrade  Phillip G. Lee 《Aquaculture International》1998,6(5):387-402

Studies were conducted to determine the potential for large scale culture of the mysid shrimp Mysidopsis almyra. Reproduction was consistent, as newly hatched mysids were always present in the culture trays. At the end of 45 day preliminary trials, the populations in the culture trays had increased 323.3% and 256.6%. A larger pilot-scale system connected to a biological filtration tank was constructed and operated for 17 weeks. Two rectangular trays (125 cm × 50 cm × 8 cm deep) were placed one above the other; water volume in each tray was 20 l. The room was kept dark. Temperatures were maintained at 26(2) °C and salinities at 20(2). A total of 1,000 adult mysids were placed in the culture tray and the hatchlings were collected and moved into a hatchling tray. Water circulation was static except for twice-daily water exchanges; newly hatched Artemia nauplii (24 h incubation) were fed to the mysids immediately after each water exchange. Feeding presented no technical problem to the pilot-scale culture of mysids in static water systems but the cost of Artemia did represent the largest expense. Mean (SD) mysid production throughout the 17 weeks of the trial was 133(69) hatchlings d–1 with highest production [244(30) hatchlings d–1] occurring between weeks 11 and 13. Mean survival in the hatchling tray after the 14 day growth periods was 41.4%. Reproduction occurred at ammonia-nitrogen and nitrite-nitrogen concentrations as high as 1.5 mg l–1 and 0.250 mg l–1 respectively, and at pH values as low as 7.6. When pH decreased to 7.38, reproduction halted abruptly and mortality increased sharply. © Rapid Science Ltd. 1998  相似文献   

Uterine neoplasia in 13 cats.

Thirteen uterine tumors were diagnosed in 13 cats and accounted for 0.29% of all feline neoplasms received during a 9.6-year period. Age at diagnosis ranged from 3 to 16 years; median 9 years. Six were Domestic Shorthair cats, and 7 were purebred cats of 5 different breeds. Eight adenocarcinomas and 1 mixed Müllerian tumor (adenosarcoma) comprised the endometrial tumors. Myometrial tumors included 3 leiomyomas and 1 leiomyosarcoma. One of the adenocarcinomas developed in the uterine stump of an ovariohysterectomized cat; the other cats were sexually intact. Concurrent mammary adenocarcinoma was diagnosed in 1 cat with uterine adenocarcinoma and in another with uterine leiomyoma. Tumors were discovered during elective ovariohysterectomy in 2 cats, but at least 3 others had experienced reproductive problems (infertility or pyometra). Five cats presented for abdominal or pelvic masses. Endometrial adenocarcinomas were positive immunohistochemically for cytokeratins and negative for smooth muscle actin (SMA): 1 of 6 cats was positive for vimentin and 4 of 8 were positive for estrogen receptor-alpha (ER alpha). Adenosarcoma stromal cells were positive for vimentin and ER alpha but negative for cytokeratins and SMA. Smooth muscle tumors were positive for vimentin and SMA and negative for cytokeratins. Leiomyomas, but not the leiomyosarcomas, were positive for ER alpha. Adenocarcinomas in 4 cats had metastasized by the time of ovariohysterectomy. Two other cats were euthanized 5 months after ovariohysterectomy; at least one of these cats had developed an abdominal mass that was not examined histologically. Only 2 cats with endometrial adenocarcinoma had disease-free intervals longer than 5 months after surgery. Metastasis was not detected in any mesenchymal tumor; however, these cats were either euthanized on discovery of the tumor or the tumor was first detected at necropsy.  相似文献   

Follicular cysts in sheep

A flock of 188 sheep was surveyed for cutaneous lesions that were noticed 3 days after shearing. On the basis of histologic features of the cyst wall, ie, association with sebaceous glands and lack of follicular structures or rete pegs, the cysts were classified as follicular cysts.  相似文献   

Precision of a fiel Method for determination of pH in dilute lakes     

John T. Turk 《Water, air, and soil pollution》1986,27(3-4):237-242

Replicate pH measurements in three dilute lakes made during extreme conditions indicate that pH can be measured in the field with a variance due to measurement error of 0.005 unit. Error of the field technique in measuring the pH of dilute solutions in the laboratory ranges from less than 0.01 unit in dilute strong-acid solutions to about 0.05 unit in air-saturated deionized water.  相似文献
