Four cows were diagnosed as having volvulus of the distal jejunoileum. Affected cattle became acutely depressed, dehydrated, and tachycardic, all developed abdominal distention, and three of four were in severe pain at the time of admission. Feces were scant or absent. The volvulus was corrected by exteriorizing the small intestine and replacing it in correct position. All four cows recovered without complications and were well 6 months or more following surgery.  相似文献   

The Medial Saphenous Fasciocutaneous Free Flap in Dogs     

DANIEL A. DEGNER DVM    RICHARD WALSHAW BVMS  Diplomate ACVS    OTTO LANZ DVM    DIANA ROSENSTEIN DVM  RICK J. SMITH MD 《Veterinary surgery : VS》1996,25(2):105-113

The purpose of this study was to identify the angiosome of the medial saphenous artery and vein and to evaluate the use of this cutaneous angiosome as a free skin flap in the dog. In phase 1 of this study, selective angiography of the medial saphenous artery performed in six canine cadavers showed that the skin covering the entire medial femorotibial area, the distal half of the caudal head of the sartorius muscle, and the gracilis muscle were perfused by the medial saphenous artery. In phase 2, a medial saphenous fasciocutaneous island flap was raised and sutured back to the skin edges of the donor wound in three dogs. One hundred percent survival of all of the flaps occurred. In phase 3, a medial saphenous fasciocutaneous microvascular free flap was transferred to a wound that was created over the dorsal metacarpal (n = 3) or metatarsal region (n = 3). The mean length ± SD of the medial saphenous vascular pedicle was 80 ± 13 mm (n = 5); the mean diameter ± SD of the medial saphenous artery was 2.8 ± 0.2 mm (n = 5) and the mean diameter ± SD of the medial saphenous vein was 4.2 ± 0.2 mm (n = 5). One hundred percent of all flaps survived (n = 6). Selective angiography of the distal cranial tibial artery (metatarsal wounds, n = 3) and the median artery (metacarpal wound, n = 3) was performed 3 weeks after surgery. All of the vascular anastomoses were patent and neovascularization of the wound beds was present. This free flap was found to be acceptable for cosmetic reconstruction of wounds located on the distal extremity.  相似文献   

Persistence studies with the herbicide sethoxydim in prairie soils     

ALLAN E. SMITH  REW I. HSIAO 《Weed Research》1983,23(5):253-257

The persistence of [¹⁴C]sethoxydim (2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexene-1-one) at the 2 μg g^?1 level was studied under laboratory conditions in three soils at 20°C and 85% of their field capacity moistures. Following extraction of the soils with methanol, the herbicide remaining was determined using radiochemical techniques. Loss of radioactivity was more rapid on moist clay loam and sandy loam, where the half-lives were 12 days, than on heavy clay in which the half-life was 26 days. Loss of radioactivity from air-dried soils (15% of field capacity) was negligible with over 94% of the applied activity being recovered after 28 days. The persistence of sethoxydim at a rate of 1 kg ha^?1 was investigated under field conditions using small plots at three prairie locations for 3 successive years. Using an oat-root bioassay procedure, no residues were detected in the 0–10 cm depths of any soils, any year, in September following May treatments.  相似文献

Cardiorespiratory Effects of Combined Midazolam and Butorphanol in Isoflurane-anesthetized Cats     

M. E. GROSS dvm    JULIE A. SMITH dvm  W. J. TRANQUILLI dvm  Dipiomate acva 《Veterinary surgery : VS》1993,22(2):159-162

The cardiorespiratory effects of midazolam (0.1 mg/kg) and butorphanol (0.4 mg/kg) were evaluated in seven cats. Cats were induced in a chamber, removed and intubated, and maintained with isoflurane in 100% oxygen. Cardiorespiratory data were recorded before and 3, 10,20,30,40,50, and 60 minutes after intravenous injection of midazolam-butorphanol. Heart rate, mean arterial pressure, and respiration rate were significantly (p < .05) decreased below baseline at various times throughout the study. Tidal volume and minute ventilation were unchanged. End-tidal carbon dioxide was significantly (p < .05) increased above baseline for 30 minutes. Midazolam-butorphanol administered intravenously induced significant alterations in several cardiorespiratory parameters in isoflurane-anesthetized cats.  相似文献   

The Effect of Occlusive and Semi-Occlusive Dressings on the Healing of Acute Full-Thickness Skin Wounds on the Forelimbs of Dogs     

PAUL W. MORGAN DVM  DVSc    ALLEN G. BINNINGTON DVM  MSc  Diplomate ACVS    CRAIG W. MILLER DVM  MVSc  Diplomate ACVS    DALE A. SMITH DVM  DVSc    ANNE VALLIANT BSc  JOHN F. PRESCOTT MA  Vet MB  PhD 《Veterinary surgery : VS》1994,23(6):494-502

This project compared the effects of hydrocolloid (HC) and hydrogel (HG) occlusive dressings and a polyethylene (PE) semi-occlusive dressing on the healing of acute full-thickness skin wounds on the forelimbs of 10 dogs. All treatments resulted in a similar degree of healing at postoperative days 4 and 7. No significant differences existed in the number of wounds that were more than 90% healed at postoperative day 28 between the group treated with the HG dressing and the group treated with the PE dressing. There were significantly fewer wounds more than 90% healed at postoperative day 28 in the group treated with the HC dressing. Wounds under the HG dressing had the largest mean percentage of contraction at postoperative days 21 and 28. Wounds under the HG dressing also had the largest contraction/re-epithelialization ratio (postoperative days 21 and 28) compared with wounds under the PE and HC dressings. Wounds under the PE dressing had a significantly higher mean percentage of re-epithelialization than wounds under both occlusive dressings on postoperative days 14, 21, and 28. Wounds under the two occlusive dressings had exuberant granulation tissue present more often than wounds under the PE dressing. The two occlusive dressings had significantly higher bacterial counts on wounds compared with wounds under the PE dressing; analysis of variance (ANOVA), P = .0008. Wounds under the HC dressing showed the poorest healing in all parameters.  相似文献   

Spontaneous regression of intracutaneous cornifying epitheliomata in a dog     

D. A. SMITH  M. K. KNOTTENBELT 《The Journal of small animal practice》1988,29(3):201-206

The clinical and histopathological features are described of a case of multicentric intracutaneous cornifying epitheliomata in a four-year-old German shepherd dog. Multiple lesions developed over a one-and-a-half year observation period. Eighteen were surgically removed, many of the others spontaneously regressed. Novel histopathological features included prominent epithelial invasion of surrounding dermis and a high mitotic rate suggestive of squamous cell carcinoma, and the apparent origin of several tumours in hair shaft epithelium.  相似文献

A root bioassay procedure for the determination of chlorsulfuron, diclofop acid and sethoxydim residues in soils     

A. I. HSIAO  A. E. SMITH 《Weed Research》1983,23(4):231-236

Measurement of the root lengths of pre-ger-minated oat seedlings (Avena sativa L. var. Sioux) grown in the dark in treated soils was used to assay residues of diclofop acid (2-[4-(2,4-dichloro-phenoxy)phenoxy]propionate) and sethoxydim (2-[1-(ethoxyimino)-butyl]-5-[2-(ethylthio)-propy]-3-hydroxy-2-cyclohexene-1-one). Similar measurements involving maize seedlings (Zea Mays L. var. Sunny Vee) were also used to determine residues of the herbicide chlorsulfuron (2-chloro-N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbony]benzenesulfonamide) in soils. The procedure appeared to be reproducible with residues of chlorsulfuron, diclofop acid and sethoxydim being detectable at amounts of 0.001, 0.2 and 0.05 μg g^?1 respectively.  相似文献
