硼中毒对固始鸡空肠发育的影响 总被引:11,自引:1,他引:11
120只1日龄固始鸡随机分为2组,分别饮用添加硼0、400mg/L的水,研究了硼中毒对固始鸡空肠发育的影响。试验期为6周,每周定时每组取鸡10只,颈静脉放血致死,取空肠,Bouin’s液固定,制作石蜡切片,HE染色,显微镜观测与拍照。结果:(1)试验组空肠绒毛长度极显著低于同周龄对照组(P〈0.01);肠腺长度第1周龄极显著低于对照组(P〈0.01),第2周龄显著低于对照组(P〈0.05)。(2)试验组1~4周龄空肠出现上皮细胞肿胀、脱落,绒毛中抽结缔组织水肿、毛细血管扩张,肠腺囊肿等痛变。试验表明,硼中毒对固始鸡小肠绒毛及肠腺发育有明显抑制和毒害作用,对机体消化吸收功能产生严重影响。 相似文献

Four cases of ulceration and stricture of the right dorsal colon were encountered. Ulceration of the right dorsal colon is generally associated with nonsteroidal anti-inflammatory drug (NSAID) toxicosis but there are few reports of stricture following ulceration. All four horses had recent phenylbutazone use: three had been given doses well in excess of the recommended dose and in one the dose was marginally above those recommended but was combined with administration of other NSAIDs. All four horses presented with intermittent low-grade colic, weight loss and ventral oedema. Diarrhoea was also seen in three of them. All had hypoproteinaemia due to severe hypoalbuminaemia, and hyperfibrinogenaemia. Hypoalbuminaemia was less severe in one horse and this horse was successfully managed medically. Two cases were definitively diagnosed at exploratory celiotomy and two at necropsy. Exploratory celiotomy was performed in two horses: one was euthanased at surgery and one was managed successfully with medical treatment and remained normal 1 year after surgery. Medical management included feeding of a low-roughage pelleted ration, corn oil, psyllium mucilloid, and discontinuation of NSAID administration. 相似文献

Objective: To provide information on the ingestion, and subsequent toxicity, of raw bread dough in dogs. Case summary: A report from the ASPCA animal poison control center (APCC) files of 3 cases of ingestion of raw bread dough by dogs. Clinical signs included vomiting, ataxia, blindness, hypothermia, and recumbency. All dogs were successfully treated for ethanol toxicosis. New information: Ingestion of bread dough can cause gastric obstruction, bloat, or ethanol toxicosis. The treatment of ethanol toxicosis, including decontamination, IV fluids, management of metabolic acidosis, and hypoglycemia is discussed. Yohimbine can be used in cases where the dog is comatose or has developed severe respiratory depression. 相似文献

A one year old female Siamese-Persian mixed breed cat in late third trimester of pregnancy was presented for anorexia and lethargy. Abdominal radiographs were normal. Abdominal ultrasound revealed markedly increased cortical and moderately increased medullary echogenicity of the maternal kidneys. Cortical echogenicity of all fetal kidneys were similarly increased in echogenicity. Premortem clinicopathologic and postmortem histopathologic findings were indicative of ethylene glycol nephrosis presumably secondary to antifreeze ingestion. 相似文献

The prevalence of subclinical hepatitis was investigated in a group of 106 randomly selected 3-year-old Doberman Pinschers. Histopathologic examination of liver samples from 65 dogs (52 dogs with high bile acids, alkaline phosphatase activity, or alanine aminotransferase activity or with copper granules in hepatocytes in a liver aspirate and 13 normal dogs) revealed subclinical hepatitis in 22 dogs (19 females and 3 males). Liver copper concentrations measured by instrumental neutron activation analysis was significantly higher (mean +/- SD; 419 +/- 414 microg/g dry matter) in dogs with hepatitis than those without liver disease (197 +/- 113 microg/g; P = .0008). At 2.6 +/- 0.6 years hepatitis persisted in 5 of 16 dogs available for examination. One dog with a high copper concentration but normal liver subsequently developed subclinical hepatitis after 3 years. During the follow-up period, the average copper concentration of the 6 dogs with persistent subclinical hepatitis was 939 +/- 299 microg/g and had continued to rise significantly (P = .02). The hepatitis in these dogs was associated with apoptotic hepatocytes and copper-laden Kupffer cells in centrolobular regions. The results of this study suggest that there is a relationship among copper storage, hepatocellular damage, and hepatitis in Doberman Pinschers. 相似文献

A 9-week-old miniature mule foal presented to the Veterinary Medical Teaching Hospital for acute blindness, ataxia, and depression following an overdose of an over-the-counter ivermectin-based de-worming medication. Ophthalmic examination and electrodiagnostic evaluation eliminated outer retinal abnormalities as the primary cause of the bilateral blindness, implicating instead a central neurologic effect of the drug. With symptomatic and supportive care, the foal recovered fully and regained its vision. 相似文献
