对巴什吐格草地自然地理环境、植被分布规律与草场类型特点研究结果表明,该区草地是中昆仑山北坡自然环境最好、植被发育最好、放牧地形最好和供水条件最好的典型草场之一。自南向北,草场植被垂直分布十分明显,东、西部植被水平分布亦有较显著差异。根据新疆草地分类系统可划分为:山地荒漠、山地草原化荒漠、山地荒漠草原、山地典型草原、高寒草原和高寒草甸6类及6个亚类、11个组、14个型。。山地荒漠草原和山地典型草原分别是冬春场和夏秋场的主体类型,各占冬春场和夏秋场草地可利用面积的4822%和6671%。结合当地草场实际,提出了草地合理开发利用的意见。 相似文献

Investigations into the analgesic effect of thiambutene and its value as a pre-anaesthetic agent were carried out in the horse and the sheep. Special emphasis was placed on the post-anaesthetic recovery period.
Thiambutene produced analgesia in both species. Toxic effects such as muscle tremor and hyperkinesia occurred with high doses. Prior administration of acepromazine increased the tolerated doses of thiambutene, and satisfactory neuroleptanalgesic states were produced.
Combined use of thiambutene and acepromazine in pre-anaesthetic medication reduced the dose of thiopentone required for anaesthesia in both species and significantly improved post-anaesthetic recovery.
Administration of nalorphine in both species reduced the duration of the recovery period. In the horse, even after prolonged thiopentone anaesthesia, nalorphine produced a shorter, quieter recovery.
It was concluded that pre-anaesthetic medication with thiambutene and acepromazine facilitated thiopentone anaesthesia and greatly reduced the problems of post-anaesthetic recovery in horses. 相似文献

锰对种蛋受精率、孵化率及蛋中锰、铜、锌浓度的影响 总被引:6,自引:0,他引:6
选用1日龄星杂“288”鉴别母雏540只进行试验,以探讨日粮中不同水平锰对种蛋受精率、孵化率、蛋中锰、铜、锌浓度的影响,以及蛋中锰含量与受精率、孵化率之间的关系。结果表明:受精率以日粮含锰110mg/kg为最高(77.18%),对照组最低(64.16%),但各组间无显著差异(P>0.05)。受精蛋的孵化率以日粮含锰70mg/kg组最高(94.85%),对照组最低(80.36%),二者差异极显著(P<0.01):雏鸡在一周内脱腱症的发生率:对照组为11.80%,日粮含锰30mg/kg组为636%,其它四组未发现。当日粮中含锰70mg/kg时,不仅可获得最佳孵化率,而且可有效地防止脱腱症的发生。日粮锰含量增高时,对蛋壳、蛋清、蛋黄中铜、锌的含量及蛋清、蛋壳中锰的含量无显著影响(P>0.05),但对蛋黄中锰含量有显著影响(P<0.01).蛋黄中锰含量随日粮锰含量的增高而增加,二者呈极显著的线性相关(r=0.9370).y=0.0168x+3.3062,r为相关系数,y为蛋黄中锰含量,x为日粮中锰含量),日粮添加锰可以显著增加蛋黄中锰含量,而对铜、锌无显著影响。 相似文献

Magnetic resonance (MR) cholangiopancreatography is useful in humans to diagnose biliary and pancreatic diseases. Some of these protocols incorporate the use of secretin, which stimulates the exocrine pancreas to release bicarbonate with secondary dilation of the pancreatic duct. We compared the utility and quality of multiple hepatic‐pancreaticobiliary MR imaging sequences before and after secretin stimulation of the pancreatic duct in five healthy cats. Multiple MR sequences were evaluated, including fast Spoiled Gradient Recalled in‐ and out‐of‐phase, Single Shot Fast Spin Echo (SSFSE), T2 Fast Spin Echo, MR cholangiopancreatography (pre‐ and postsecretin administration), and Fast Acquisition with Multiphase Efgre (FAME) (postsecretin and before and after gadolinium administration). The MR cholangiopancreatography protocol with secretin stimulation was feasible and yielded high‐contrast maps of the biliary ductal anatomy but the pancreactic duct was seen inconsistently. The FAME series most consistently provided visualization of biliary and postsecretin pancreatic ductal anatomy, combined with very good depiction of the liver and pancreas. The remaining sequences each had satisfactory utility and diagnostic quality, with the exception of the SSFSE sequences. Secretin improved the conspicuity of the pancreatic duct. 相似文献

Resistive index (RI) and pulsatility index (PI) are indirect measurements of blood flow resistance that may be used to evaluate vascular changes in renal and ophthalmologic diseases. To our knowledge, no reports are available describing values for renal and ocular PI index in the unsedated dog and ocular RI and PI indices in the unsedated cat. The purpose of this study was to measure normal values for both intrarenal and ocular RI and PI within the same subject in unsedated clinically normal dogs and cats. Twenty-seven dogs and 10 cats were considered healthy by means of physical examination, CBC, biochemical profile, urinalysis, and ultrasonography. Systolic blood pressure was measured by Doppler ultrasonography. Intrarenal and ocular arteries were scanned by pulsed Doppler ultrasonography to calculate RI and PI. No significant differences were noted between the values obtained for the right vs. the left kidney and eye. The upper values of these indices were calculated as mean+2 standard deviations resulting in 0.72 and 1.52 for dog renal RI and PI; 0.7 and 1.29 for cat renal RI and PI; 0.76 and 1.68 for dog ocular RI and PI; and 0.72 and 1.02 for cat ocular RI and PI. 相似文献

SUMMARY: The prevalence of Dirofilaria immitis infection in dogs continues to increase in the temperate east coast zone of Australia (and is extending further south into New South Wales and Victoria). However, the infection rate has not changed in the tropics over the past 10 years where it would appear that a maximum infection rate of 90% occurs in a given Australian dog population. Twelve percent of Brisbane dogs had occult dirofilariasis and it is suggested that the proportion of occult infections was probably higher in the tropics. Dogs of all breeds appear equally susceptible to D. immitis with infection being more common in older male dogs. The level of microfilaraemia was, occasionally, proportional to the number of heartwprms per dog. Toxocara canis was present in about 75% of dogs from all areas studied except in Central Australia where the level of infection was much lower.
Immunodiagnosis of D. immitis and T. canis with high specificity and sensitivity was achieved by cyanogen bromide indirect fluorescent antibody and cell-mediated immunity tests using parasite antigens purified by affinity chromatography. These tests enabled occult dirofilariasis to be differentiated from unrelated canine cardiac and pulmonary failure. Such immunodiagnosis can aid in the early diagnosis of dirofilariasis particularly in situations where no circulating microfilariae can be detected.
The prevalence of serum antibody in man to purified Dirofilaria and Toxocara antigens was proportional to the incidence of respective canine infections at each location. 相似文献
