Growth Hormone Receptors in the Porcine Testis During Prepuberty     

MR N'Diaye  SS Sun  SP Fanua  KJ Loseth  EF Shaw Wilgis  BG Crabo 《Reproduction in domestic animals》2002,37(5):305-309

Supplementation of exogenous growth hormone (GH) during prepuberty advances onset of spermatogenesis in boars, but the mechanism of action is unknown. The present study is an investigation of the presence and characteristics of testicular growth hormone receptors (GHR). A total of 36 boars were castrated, three boars every 10 days, between the ages of 10 and 120 days. Testicular membrane preparations of 10, 20, 30, 50, 70, 100 and 120‐day‐old boars were used to determine ¹²⁵I‐bGH binding and Scatchard analysis. Liver from a 60‐kg barrow was used for comparison. Specific ¹²⁵I‐bGH binding to testicular membrane preparations occurred in all age groups with the exception of 20‐day‐old boars at levels of 30–40% of liver binding. At 30 days of age the unlabelled bGH at 1.1 ng/tube achieved half maximal inhibition (ID₅₀). Results of Scatchard analysis indicated a single class of binding sites. Binding affinity was 2.89 × 10⁹m with a binding capacity of 12 fmole/mg membrane protein. The results from this study suggest that GH may act directly on the cells of the prepubertal boar testis.  相似文献   

Improved codistillation method for determination of carbon tetrachloride, ethylene dichloride, and ethylene dibromide in grain and grain-based products     

J W DeVries  P A Larson  R H Bowers  J A Keating  J M Broge  P S Wehling  H H Patel  J W Zurawski 《Journal of the Association of Official Analytical Chemists》1985,68(4):759-762

A method is described for the determination of the common fumigants carbon tetrachloride (CCl4), ethylene dichloride (EDC), and ethylene dibromide (EDB) in grain and grain-based products. A properly prepared sample is mixed with water and hexane, an internal standard mixture of 1,2-dichloropropane (DCP) and 1,2-dibromopropane (DBP) is added, and the fumigants are codistilled with the hexane into an appropriate receiver. After the hexane solution is dried over sodium sulfate, the quantities of fumigants present are quantitated on a gas chromatograph (GC) equipped with an electron capture detector (ECD). For the matrices investigated, the relative standard deviation of the method was 6.0, 9.7, and 23.1% for CCl4, EDC, and EDB, respectively. Recoveries of added fumigants were 107, 95, and 101%, respectively. Comparison with an acetone-water soak extraction method gave a correlation of 0.967 between methods for EDB with odds of a difference between methods of 35%.  相似文献

Acute cortisol responses of lambs castrated and docked using rubber rings with or without a castration clamp     

AS DINNIS  KJ STAFFORD  DJ MELLOR  RA BRUCE  RN WARD 《Australian veterinary journal》1997,75(7):494-496

Objective To measure the plasma cortisol response in lambs castrated and docked by three different methods (ring castration and tail docking, ring and clamp castration and tail docking; ring and clamp castration and ring tail docking) for 4 h after treatment.
Design A physiological study with controls.
Procedure A rubber ring was applied to the scrotum. Then the castration clamp was placed, distal to the ring, on each spermatic cord such that there was no overlap of the crush lines.
Results There were no differences in the cortisol secretion of the lambs castrated and tail docked by the ring only and by the ring plus castration clamp methods. Using the castration clamp in addition to the ring on the tail had no effect on cortisol secretion.
Conclusions Using the castration clamp did not appear to reduce the cortisol response to ring castration and docking, as demonstrated elsewhere, because the areas of uncrushed tissue between the two castration clamp crush lines allowed nociception from ischemic scrotal tissue to be transmitted cranially via undamaged nerve fibers.  相似文献

Resolution of hyphaema following intracameral injection of tenecteplase in a Stock Horse     

DI Rendle  KJ Hughes 《Australian veterinary journal》2013,91(1-2):31-34

Intracameral injection of tissue plasminogen activator has been suggested as a means of hastening the clearance of blood from the anterior chamber and reducing the risk of synechia and fibrotic membrane formation in horses with hyphaema. The following report describes a case of ocular trauma in which intracameral injection of tenecteplase (TNK), a new‐generation plasminogen activator, resulted in rapid resolution of hyphaema and successful outcome. However, a large dose (1 mg) was administered and may have been associated with retinopathy and keratopathy. TNK may be an effective treatment for equine hyphaema and further controlled clinical or experimental studies are required to determine its efficacy and safety profiles.  相似文献   

A Survey of Logger Concerns When Working with Small Woodland Owners     

Tamara L. Cushing  Francisca Belart  Steve Bowers 《Small-Scale Forestry》2018,17(4):523-534

Many small woodland owners will harvest timber only once in their lifetime. Their expectations of a logging operation do not often match with reality. On the other side of the equation, loggers express frustration when working with small woodland owners. The jobs are smaller and often come with complications not found with industrial forest owners. Adding to this is the fact that the two parties often aren’t speaking the same language. In order to better prepare landowners for this operation, we surveyed logging contractors to learn about the interactions with small woodland owners in Oregon, USA. The mail survey focused on how jobs were bid, use of contracts, and difficulties that loggers had when working with small woodland owners. Results provide information that confirms the challenges present when working with many individual owners who do not have experience with harvest operations. Survey results also confirm that the logging workforce in Oregon is aging on average. Results showed no correlation between the number of years working as a logger and responses to other questions.  相似文献
