Unilateral laparoscopic cryptorchidectomy in a llama     

Zulauf M  Bergadano A  Steiner A 《Schweizer Archiv für Tierheilkunde》2002,144(5):233-237

Cryptorchism is an inherited congenital abnormality characterized by the failure of one or both testes to descend into the scrotum. Diagnosis can be difficult if the retained testicular tissue cannot be localized during clinical examination and the history of the animal is unknown, or if the animal shows persistent male behaviour despite the history of successful previous castration. The present case report describes the history of a cryptorchid Lama and the techniques of general anesthesia and laparoscopic cryptorchidectomy advocated.  相似文献   

Treatment of temporary upward fixation of the patella in an alpaca by abrasion trochleoplasty and imbrication of the medial retinacular fascia     

Zanolari P  Tschudi M  Rytz U  Steiner A 《The Veterinary record》2002,150(24):752-754

A two-year-old female alpaca suddenly became lame on its right hindlimb. Eight days later clinical and radiographic examinations showed that the patella had become temporarily fixed within the supratrochlear notch of the femur. Under general anaesthesia an abrasion trochleoplasty followed by fascial imbrication was carried out. After two weeks in supporting slings, the animal put full weight on the leg, and six months after the surgery it showed no signs of lameness or recurrence of the upward fixation.  相似文献   

Endometrial Adenocarcinoma and Mucometra in a 6-year-old Alaska Malamute Dog     

FJ Pena  JA Gines  J Duque  V Vieitez  R Martinez –Pérez  L Madejón  I Nuñez Martinez  JM Moran  S Fernández-García 《Reproduction in domestic animals》2006,41(2):189-190

A 6-year-old female Alaska Malamute dog was presented for evaluation of abdominal enlargement referred by a local veterinarian. On the history, the owner complained of chronic abdominal enlargement initiated more than 4 months ago, reduced appetite, occasional vomiting and general dullness. He also complained of greenish mucous intermittent vaginal discharge starting 10 days ago. The bitch was chronically treated with medroxiprogesterone acetate. A laparatomy was performed and fluid in the abdomen was found and aspirated during the surgery. Also a very fluid-filled distended uterus and a mass in the distal part of the left uterine horn were found. The mass was encapsulated by the omentum, but areas of necrosis and calcification were identified. Histopathological diagnosis was endometrial adenocarcinoma.  相似文献   

Apoptosis-independent Poor Morphology of Bovine Embryos Produced by Multiple Ovulation

In multiple ovulation and embryo transfer (MOET) programmes in cattle, a considerable number of morphologically poor-quality embryos continue to be produced; this is one of the limiting factors of the technique. Apoptosis has often been implicated in developmental arrest and fragmentation; these are regarded as poor traits of embryonic quality in mammalian pre-implantation embryos. In the present study, apoptosis was assessed in morphologically poor-quality embryos in comparison with good-quality embryos that were recovered from a MOET programme. Retarded embryos (two to 16 cell stage), morulae with severe fragmentation and morphologically good-quality morulae recovered from superstimulated cows at day 7 post-insemination were subjected to TdT-mediated dUTP nick-end labelling (TUNEL) and Hoechst staining. Cell nuclei that showed both TUNEL staining and apoptotic morphology were considered to be apoptotic. Apoptotic index (AI) was calculated as the percentage of apoptotic cells per embryo. Fifteen of 17 retarded embryos and 10 of 15 morphologically poor-quality morulae did not show signs of apoptosis. The mean AIs in the morphologically poor-quality embryos (two to 16 cell stage, 2.2%; poor morulae, 1.3%) were as low as that in the good-quality embryos (2.9%). These results suggest that another mode of developmental arrest and/or fragmentation that is independent of apoptosis occurs in morphologically poor-quality embryos recovered from MOET programmes.  相似文献

Winteraktive Spinnen auf einem Acker bei Groβenzersdorf (Niederösterreich)     

K. Thaler  H. M. Steiner 《Journal of pest science》1975,48(12):184-187

Ground spiders on a cultivated field near Groβenzersdorf (Lower Austria) in the winter months 322 adult spiders caught with pitfall traps on a field near Groβenzersdorf in the period 3. X 1973–5. III 1974 showed: Erigonidae, Linyphiidae,Pachygnatha (Tetragnathinadae) are dominating. 19 spp. have been recognized, most of them being already known as eurochronous or diplochronous respectively. The whole spider fauna resembles very mmuch the situation found in mid-Germany (Leipzig) byGeiler (1963).  相似文献
