Successful small intestinal resection and anastomosis in a late term broodmare with colic via a standing left flank laparotomy

A late term broodmare presented with low‐grade intestinal colic. Clinical findings were consistent with a small intestinal lesion requiring surgical intervention. The risks of general anaesthesia to the fetus, combined with clinical findings in an otherwise quiet natured horse influenced the decision to choose an alternative standing left flank approach first. A small intestinal resection and anastomosis was performed successfully and the mare delivered a healthy foal without complications a month later. Standing colic surgery might be a preferred alternative to general anaesthesia in certain circumstances as discussed in this case report.     

Accessory nictitating membrane in a Lipizzaner colt

A 2‐year‐old Lipizzaner colt presented for removal of a mass over the left eye. The colt had no blepharospasm or significant ocular discharge, but the cornea underlying the mass was mildly oedematous. The mass protruded from the conjunctiva at the dorsotemporal aspect of the globe and was covered in normal conjunctiva. It had a gross appearance similar to the cartilaginous flap of a nictitating membrane, but in an aberrant location. It was moveable to cover the dorsal aspect of the cornea when the globe was retropulsed. Excision of the mass under general anaesthesia was elected. Histopathology supported a diagnosis of an accessory nictitating membrane, consisting of a cartilaginous band surrounded by glandular epithelium. The colt recovered from surgery without complication and no problems were reported by the owner at 8.5 months post‐operatively. To the author's knowledge, there have not been previous reports of accessory or ectopic nictitating membranes in equine or other species.     

Intra‐abdominal cystic lymphangiomatosis in a Thoroughbred foal

Cystic lymphangiomas are rare malformations of the lymphatics that result in the formation of a cystic mass. Where multiple cysts are seen, the condition is termed cystic lymphangiomatosis. This case describes the diagnosis and unique management of cystic lymphangiomatosis in a 10‐day‐old Thoroughbred foal. Ultrasonography, histopathology and laparoscopy were essential for diagnosis and appreciation of the extent of disease. Ultimately, the cystic lymphangiomatosis was so extensive in this foal that complete surgical excision was considered impossible and the presence of adhesions within the abdomen indicated a very poor long‐term prognosis; the owners elected for euthanasia at age 14 weeks. Although rare, lymphangioma and lymphangiomatosis should be considered as a differential diagnosis for an intra‐abdominal mass in a young horse.     

植酸酶对不同类型的断乳仔猪日粮粗蛋白、氨基酸和能量的消化率的影响

通过对4个安装了简易T型瘘管的断奶仔猪研究表明,添加植酸酶并没有提高玉米-豆粕型日粮(试验组1)、小麦-豆粕型日粮(试验组2)和大麦-豌豆-菜籽粕型日粮(试验组4)粗蛋白和氨基酸的回肠表观消化率(AID),而使小麦-豆粕-菜粕型日粮的粗蛋白和氨基酸回肠表观消化率或粗蛋白和消化能的总消化道表观消化率(ATTD)得到了显著的提高(P<0.05)或呈提高的势态(P<0.10)。这些结果表明,氨基酸对细菌性植酸酶的反应因子取决于日粮的组成。     

利用黄土中碳同位素推断古植被类型

黄河中游黄土高原生态环境十分脆弱,已成为中国乃至世界林业、农业、地质和环境专家关注的热点地区.黄土地层中保存着大陆上最完整、最连续的古气候记录(顾兆炎,1991).黄土沉积以黄土层和古土壤层交互沉积为特征.学者们已从各个角度来挖掘这些记录,以探寻最好的气候指标,提取可靠的古气候、古植被信息.     

水黄皮叶斑病的成因、严重性及杀菌剂防止

对孟加拉国4个苗圃(IFES、IFESCU、BFRI和ANC)内水黄皮叶斑病症状和严重性进行了调查,结果表明:IFESCU苗圃内叶斑病侵染率及致病指标最高、BFRI次之、ANC最低.与叶斑病相关联的组织从发病植株分离出来,被分离的真菌形成致病性.结果证实胶孢炭疽菌即为致病菌.观察了杧果炭疽病菌丝体生长抑制性并对杀菌剂(Bavistin, Cupravite and Dithane M-45) 有效性和浓度(0.05, 0.10, 0.50, 1.00, 1.50 和 2.00%)进行了鉴定.0.05% Bavistin和Cupravite潜伏8天后,菌丝体生长分别处于最低和最高水平.结果表明:Bavistin杀菌效果最好、Diathane M-45次之,Cupravite对菌丝体生长的抑制作用最低.图1表4参27.
