Mammary gland tumors in male dogs     

Saba CF  Rogers KS  Newman SJ  Mauldin GE  Vail DM 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2007,21(5):1056-1059

BACKGROUND: Reports of mammary-gland tumors in male dogs are lacking. OBJECTIVE: To describe the clinical characteristics of mammary-gland tumors in male dogs. ANIMALS: Eight male dogs diagnosed with mammary-gland tumors. METHODS: Retrospective study. Medical databases from 3 institutions were searched. Medical records were abstracted, and owners and referring veterinarians contacted for follow-up information. Tissues were reviewed for histologic type, and immunohistochemical staining for estrogen and progesterone receptors (ER, PR) was performed. RESULTS: Eight dogs with histologically confirmed mammary-gland tumors were included in this retrospective study. Median age at diagnosis was 11.5 years. Four dogs were sexually intact; 4 were neutered. All were purebred. Mammary-gland tumors were incidental findings in 7 of 8 dogs. All dogs were treated with only surgical excision. All but 1 dog had benign epithelial tumors. The dog with the malignant tumor was the only dog to develop possible local recurrence but de novo tumor development cannot be excluded. No dog had evidence of metastatic disease at diagnosis. Based on institutional population data, it was determined that female dogs are 62 times more likely to develop mammary-gland tumors than male dogs (P < .001). Estrogen-receptor expression was strong in the majority of tumors; progesterone-receptor expression, although present in all tumors, was less intense. CONCLUSIONS/CLINICAL IMPORTANCE: This study suggests that mammary-gland tumors in male dogs are rare, usually benign, and surgery alone can provide long-term control in most dogs.  相似文献   

Limited genetic structure among broad-scale regions for two commercially harvested,tropical deep-water snappers in New Caledonia

We estimated the spatial population connectivity of Etelis carbunculus and E. coruscans based on measures of population genetic structure using the mitochondrial DNA control region. We collected samples from three areas separated by a minimum of 200 km around New Caledonia. We identified two separate genetic groups for E. carbunculus and a single group for E. coruscans. There were many singleton haplotypes distributed among geographic regions, indicating minimal spatial differentiation in genetic structure between regions for each species, although one of the genetic groups for E. carbunculus was in only two of the three regions. Conservation and management directives should consider both species as a single genetic stock among these three widespread regions. Our results provide evidence that stock structure might be less variable in the South Pacific than reported elsewhere, possibly indicating that trans-boundary management may be required in this region for deep-water snapper fisheries. Further refinement (including taxonomy) is required for E. carbunculus to characterize the different lineages observed.  相似文献

Supplements Containing Escape Protein Improve Redberry Juniper Intake by Goats     

Chad H. George  Cody B. Scott  Travis R. Whitney  Corey J. Owens  Brian J. May  Richard Brantley 《Strength and Conditioning Journal》2010,63(6):655-661

Redberry juniper (Juniperus pinchotii Sudw.) is a common invasive plant species in west-central Texas. Goats will consume redberry juniper, but intake is limited by monoterpenoids found in the plant. Previous research has shown that goats will increase juniper intake through 1) conditioning and 2) protein supplementation. This study compared intake of juniper when goats received different protein supplements either with or without protein sources that are high in amino acids that escape digestion in the rumen. Recently weaned Boer-cross goats (n = 47) were randomly placed into five treatments. Treatments 1, 2, 3, and 4 received a protein supplement and juniper for 1 h daily for 14 d, along with a basal diet of alfalfa pellets (2% body weight). Treatment 5 received only a basal diet of alfalfa pellets and juniper. All supplements were formulated to be isonitrogenous (37% crude protein [CP]). Treatment 1 contained cottonseed meal (high CP escape value), treatment 2 contained cottonseed meal and distiller’s dried grain (higher CP escape value), treatment 3 contained soybean meal (low CP escape value), and treatment 4 contained soybean meal and distiller’s dried grain (moderate CP escape value). Refusals of juniper, supplements, and alfalfa were weighed daily to determine intake. Supplementation with 1) cottonseed meal, 2) soybean meal, or 3) soybean meal and distillers dried grain did not influence (P > 0.05) juniper intake. Conversely, goats supplemented with cottonseed meal and distiller’s dried grain ate more (P < 0.05) juniper than goats receiving only alfalfa, possibly because of increased escape of glucogenic amino acids. We contend that supplementation with feeds high in protein escape values should increase juniper intake on rangelands.  相似文献   

Indirect computed tomography lymphangiography with aqueous contrast for evaluation of sentinel lymph nodes in dogs with tumors of the head          下载免费PDF全文

Sentinel lymph node evaluation is widely used in human medicine to evaluate the first lymph node(s) to which a tumor drains. Sentinel lymph node biopsy allows avoidance of extensive lymphadenectomies in cases where the sentinel lymph node is negative for metastasis, thereby reducing patient morbidity. It has been shown that regional lymph nodes are not always the sentinel lymph node, thus identification and sampling of sentinel lymph nodes allows for more accurate staging, which is critical for treatment and prognostication in dogs with cancer. The objective of this prospective, pilot study was to determine if indirect computed tomography (CT) lymphangiography with aqueous contrast agent would successfully allow identification of sentinel lymph nodes in dogs with masses on the head. Eighteen dogs underwent CT lymphangiography. The sentinel lymph node was successfully identified within 3 min of contrast injection in 16 dogs (89%). Compression of lymphatic vessels from endotracheal tube ties and/or the patient's own body weight delayed or prevented identification of sentinel lymph nodes in two dogs (11%). Computed tomography lymphangiography with aqueous contrast can be used successfully to rapidly identify sentinel lymph nodes in dogs with masses on the head.  相似文献

Occurrence of hepatocellular carcinoma in an adult male Nile lechwe (Kobus megaceros).     

Floyd D Wilson  Scott D Fitzgerald  Matti Kiupel  Rodney L Walker  Corey B Williams  Donna J Todd 《Journal of zoo and wildlife medicine》2007,38(2):329-332

A 14-yr-old male Nile lechwe (Kobus megaceros) from the Jackson Zoo (Mississippi, USA) had chronic weight loss that was associated with elevated serum alkaline phosphatase levels. Approximately 4 yr after the first clinical signs of weight loss, the animal fractured its left rear femur and was subsequently euthanized; on the same day necropsy was performed. The liver was grossly enlarged and contained a smooth-surfaced nodular mass that occupied the majority of the right lobe of the liver. The mass had a liver-like appearance exhibiting a tan-red coloration but having a soft consistency. A single, approximately 0.6 cm, round, slightly elevated discrete red nodule was present in the left anterior lung. Microscopically, the hepatic mass and pulmonary nodule diffusely consisted of irregular cords of cells exhibiting hepatoid features, but containing no evidence of normal portal bile duct or portal triad development. To our knowledge, this is the first report in the scientific literature of a naturally occurring case of hepatocellular carcinoma in a Nile lechwe or in any antelope species.  相似文献   

Using Experience and Supplementation to Increase Juniper Consumption by Three Different Breeds of Sheep     

Jess R. Anderson  Cody B. Scott  Charles A. Taylor  Corey J. Owens  James R. Jackson  Diana K. Steele  Richard Brantley 《Strength and Conditioning Journal》2013,66(2):204-208

In the southwestern United States, redberry (Juniperus pinchotii Sudw.) and ashe (Juniperus ashei Buchholz) juniper are two invasive species that dominate some rangelands. Goats will consume up to 30% of their diet in juniper, but it is unknown if sheep will accept juniper to the same extent. The objectives of this study were to determine if sheep can be conditioned to consume juniper and to compare intake among different breeds. Rambouillet (n = 10), Suffolk (n = 10), and Dorper-cross (n = 10) lambs were randomly placed in individual pens for 31 d. A basal diet of alfalfa pellets (2.5% body weight [BW]) and juniper were fed. Juniper was fed each morning from 0800 to 0830 hours. The basal diet was fed for the remainder of the day. Intake of each was measured daily. Following the first 17 d, the basal diet was reduced to 2% BW for 7 d and then reduced to 1.5% BW for the final 7 d. Serum aspartate transaminase (AST), gamma glutamyltransferase (GGT), blood urea nitrogen (BUN), creatinine, and bilirubin levels, and live body weight were measured to assess any adverse physiological effects from juniper consumption. In a second trial, lambs were again fed alfalfa (2.5% BW) and juniper. One half of the lambs were also fed a 36% protein supplement to determine if supplementation with protein sources that escape rumen degradation would improve juniper consumption. Lambs received alfalfa, juniper, and protein supplement for 22 d with intake of each recorded daily. Intake of juniper was similar (P > 0.05) among breeds of sheep. Lambs readily consumed juniper and increased (P < 0.05) intake of juniper as the amount of alfalfa fed was reduced. Weight change was also similar among treatments. Protein supplementation did not improve juniper consumption. We contend that sheep will consume a diet consisting of 24% juniper without experiencing any adverse effects.  相似文献
