A ten‐year‐old, male castrated Springer Spaniel was presented for dysphagia, ptyalism, and regurgitation. Evidence of megaesophagus and mild aspiration pneumonia were apparent on thoracic radiographs. A diagnosis of focal acquired myasthenia gravis was suspected and subsequently confirmed with a positive serum acetylcholine (ACh) receptor antibody concentration (3.87 nM/L). A gastrostomy tube was placed shortly after presentation; food and drugs (including azathioprine) were administered through the tube. After transient improvement, the dog suddenly deteriorated clinically, experiencing frequent episodes of regurgitation and developing severe aspiration pneumonia. Mycophenolate mofetil (MMF), a novel immunosuppressive drug with relative specificity for lymphocytes, was instituted every twelve hours via the gastrostomy tube. Within four days of beginning MMF therapy, both clinical evidence of pharyngeal/esophageal dysfunction and radiographic evidence of megaesophagus had resolved. Initially, clinical side‐effects of combined MMF/AZA administration were not apparent, but the patient experienced several vomiting episodes during the third week of treatment. The vomiting resolved after decreasing the dose of both drugs. The patient made a full recovery, and a one‐month follow‐up ACh receptor antibody concentration was normal (0.26 nM/L). After one month of combination therapy, the patient was weaned off of AZA and maintained on MMF as the sole immunosuppressive drug. The dog was subsequently weaned off of MMF on two occasions. Mycophenolate mofetil was reinstituted after the first discontinuation due to the development of profound appendicular muscle weakness two days after stopping MMF; the weakness resolved within 24 hours of reinstituting MMF. A positive ACh receptor antibody concentration (0.89 nM/L) after the second MMF weaning prompted the second reinstitution of MMF. Two months following this second MMF reinstitution, the dog was again serologically negative (0.51 nM/L) for myasthenia gravis. At the time of last followup, the dog remained in clinical remission eight months after initial presentation. The use of MMF to treat acquired myasthenia gravis in dogs has not been reported previously. The literature concerning MMF and its potential use in treating patients with autoimmune diseases is discussed.  相似文献

叶清华  李泽坤  张舒婷  周相助  谢倩  陈清西 《热带作物学报》2018,39(12):2479-2485

提取箬竹和马尾松叶片总黄酮作为天然保鲜剂用于橄榄浸泡处理，以研究竹叶和松针黄酮提取液对橄榄果实 的保鲜效果。结果表明，不同浓度的竹叶和松针黄酮提取液均能对橄榄果实起到一定的保鲜作用，其中 393 mg/L 竹叶 黄酮提取液、330 mg/L 松针黄酮提取液处理的橄榄果实好果率均高于对照，贮藏第 77 天时，橄榄好果率分别为 76.11%、 78.89%。2 种处理均可延缓果实可溶性总糖含量下降，促进多酚含量下降，提高橄榄果实的糖酚比，能有效改善橄榄 果实贮藏期内的鲜食品质。  相似文献   

ULTRASOUND-GUIDED FINE-NEEDLE ASPIRATION     

Marc  Papageorges  DMV  MSc  Patrick R.  Gavin  DVM  PhD  Ronald D.  Sande  DVM  PhD  David D.  Barbee  DVM  MS 《Veterinary radiology & ultrasound》1988,29(6):269-271

A simple and inexpensive modification of the ultrasound-guided fine-needle aspiration biopsy technique using an extension tube attached to the needle is described. One operator can easily manipulate the ultrasound transducer and biopsy needle while monitoring the entire procedure. This simple modification was found to facilitate ultrasound-guided fine-needle aspiration.  相似文献   

FLUOROSCOPICALLY GUIDED PERCUTANEOUS FINE-NEEDLE ASPIRATION BIOPSY OF THORACIC LESIONS IN DOGS AND CATS     

Marjorie C.  McMillan  DVM  Lawrence J.  Kleine  DVM  MS  James L.  Carpenter  DVM 《Veterinary radiology & ultrasound》1988,29(5):194-197

Forty-eight fine-needle aspiration biopsy specimens of intrathoracic lesions were obtained with a Westcott needle by localizing needle placement using TV-monitored, image-amplified fluoroscopy and by detecting changes in tactile sensation. Thiryt-five lesions were pulmonary in origin and 13 were within the mediastinum. Most biospy specimens were obtained with the patients sedated, however, general anesthesia was used in one patient to prevent movement that could have resulted in puncture of a critical structure. The only clinical and radiographic complication from this procedure was pneumothorax, occurring in eight dogs and resulting in one death. Definitive diagnoses were made from tissue obtained from 37 of the 48 lesions sampled for a sensitivity rate of 77.1%. Fine-needle aspiration biopsy was found to be a simple, safe, and accurate diagnostic technique.  相似文献   

湿地松针叶中的松脂含量及其单萜,倍半萜的组成与抗褐斑病的关系   总被引：3，自引：0，他引：3  

叶建仁  尚征贤 《植物病理学报》1995,25(3):265-269

 研究分析了湿地松20个抗病无性系和14个易感株针叶中的松脂含量,结果表明抗病湿地松针叶中的松脂含量为7.17%,明显比易感株含量5.46%高。顶冠针叶的松脂含量与侧枝针叶的含量基本相近。对9个抗病无性系和4个易感株针叶挥发油中的单萜和倍半萜研究表明,湿地松针叶中的单萜和倍半萜的种类较多,不同无性系(或单株)间高含量单萜和倍半萜种类较稳定,某些低含单萜组分与抗病性之间存在着一定的联系。抗病无性系针叶中都缺乏在感病针叶中普遍存在的异龙脑和香草醇。  相似文献

From field investigations and inoculations,Dothistroma pini,the pathogen ofDothistroma needle blight was found to overwinter as mycelium and unmatured acervuli in infectedneedles.The conidia were spreaded mainly by rain splash.The disease became widespread by trans-porting discased seedlings and seions conidia spread throughout the growing season,but mainlyfrom May to July.The diseade was found in both stand locations in each summer of investigation.The outbreak severity was serious in pure stands of susceptible pine and mixed stands with largecomponents of suseeotuble pine.but slight in mixed stands of unsusceptible species with small com-ponents of suseeptible hosts.The disease was less severe in pruned stands than in unpruned stands.The disease was most serious near the infection centre.indoor and outdoor tests,it was shown thatChlorothalonil smoke,Chlorothalonil spray and Thiram and Asomate sprays were effective controlfungicides.  相似文献   

Fine needle aspiration cytology and histologic correlation in canine tumors     

Griffiths GL  Lumsden JH  Valli VE 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1984,13(1):13-17

Fine needle aspiration biopsy was performed on 147 skin tumors in 119 dogs over a 4-year period. Both air-dried smears (Wright's stain) and wet-fixed smears (Papanicolaou's stain) were prepared from the aspirates from each tumor and the cytological diagnosis was correlated with histology. In 105 tumors, the cytological and histological interpretations agreed. Histologically, there were 36 stromal tumors, including 19 fibrosarcomas and nine hemangiosarcomas. Cytologically, 12 of the fibrosarcomas and five of the hemangiosarcomas were interpreted correctly as malignant tumors. All 11 melanomas and all 37 mast cell tumors were identified correctly cytologically, while nine of the 11 squamous cell carcinomas, 15 of 21 adenocarcinomas and eight of 19 mammary carcinomas were interpreted as malignant using aspiration biopsy. The fine-needle technique also identified 16 dogs with metastases to the regional lymph nodes before surgical biopsies were undertaken. Benign tumors were incorrectly described as malignancies in only three cases.  相似文献

Revealing past needle density in Pinus spp.     

《Scandinavian Journal of Forest Research》2012,27(1-4):292-296

The number of short shoots per shoot length, or needle density, is species typical, and it shows year‐to‐year variation within species. By modification of the needle trace method, long‐term needle density chronology was produced in a Scots pine (Pinus sylvestris L.) stand, located at the northern timberline in Finland. Treewise, needle density varied between 9 and 14 short shoots per long shoot (stem internode) centimetre, the annual minimum and maximum values being 5 and 37 short shoots cm^?1. The stand‐specific long‐term average was 10.5 short shoots cm^?1, and the mean annual value varied between 17 and 8 short shoots cm^?1 in 1951 and 1984, respectively. The long‐term pattern in needle density was one of decline with time between 1950 and the mid‐1970s, then to slightly increase on entering the 1990s. The years when the density was relatively high were 1957, 1968 and 1981, indicative of some climatic extremes.  相似文献
