Heartworm disease caused by Dirofilaria immitis affects canine and feline hosts, with infections occasionally being reported in humans. Studies have shown that both dirofilarial
antigens and those derived from its bacterial endosymbiont Wolbachia, interact with the host organism during canine, feline and human infections and participate in the development of the pathology
and in the regulation of the host’s immune response. Both innate and acquired immune responses are observed and the development
of the acquired response may depend on the host and, or on its parasitological status. This review aims at illustrating current
research on the role of both D. immitis and Wolbachia, in the immunology and immunopathology of dirofilariosis. 相似文献

Background: The coadministration of prednisone and ultralow-dose aspirin has been recommended for the management of various diseases, but the safety of this combination in dogs has not been studied.
Hypotheses: The gastroduodenal lesions associated with prednisone and ultralow-dose aspirin administration will be similar to those caused by prednisone alone, but both treatments will result in more severe lesions than placebo.
Animals: Eighteen healthy adult purpose-bred dogs.
Methods: Randomized, blinded, placebo-controlled study of 3 treatment groups for 27 days: placebo, prednisone, and prednisone and aspirin. Gastroduodenoscopy was performed before and on days 5, 14, and 27 of treatment and mucosal lesions scores were assigned. Mucosal lesion scores were compared by a Kruskal-Wallis test. Clinical signs were compared by the Friedman's chi-square test (significance at P < .05).
Results: There were no significant differences in the gastroduodenal lesion scores among groups, or within groups at any time during the study. Significantly more dog-days of diarrhea occurred in the prednisone and aspirin group during treatment, compared with baseline. No significant differences in clinical signs were found among any of the groups.
Conclusion: The concurrent use of prednisone and ultralow-dose aspirin did not increase the severity of gastroduodenal lesions compared with prednisone or placebo. Coadministration of prednisone and ultralow-dose aspirin increases the frequency of mild, self-limiting diarrhea in some dogs. 相似文献

OBJECTIVES: To discuss the clinical pharmacology of currently licensed veterinary NSAIDs and to review gastrointestinal and renal adverse effects as well as drug-drug interactions that have been reported with these drugs. To review the use of NSAIDs in the peri-operative setting and their use in patients with osteoarthritis. To further review the reported effects of NSAIDs on canine articular cartilage and liver as well as the clinical relevance of a washout period. DATABASES USED: PubMed, CAB abstracts and Google Scholar using dog, dogs, nonsteroidal anti-inflammatory drugs and NSAID(s) as keywords. CONCLUSIONS: A good understanding of the mechanisms by which NSAIDs elicit their analgesic effect is essential in order to minimize adverse effects and drug-drug interactions. Cyclooxygenase (COX) is present in at least two active isoforms in the body and is the primary pharmacologic target of NSAIDs. Inhibition of COX is associated with the analgesic effects of NSAIDs. COX is present in the gastrointestinal tract and kidneys, along with other areas of the body, and is also the likely reason for many adverse effects including gastrointestinal and renal adverse effects. The newer veterinary approved NSAIDs have a lower frequency of gastrointestinal adverse effects in dogs compared to drugs such as aspirin, ketoprofen and flunixin, which may be due to differential effects on the COX isoforms. There are currently no published reports demonstrating that the newer NSAIDs are associated with fewer renal or hepatic adverse effects in dogs. NSAIDs remain the cornerstone of oral therapy for osteoarthritis unless contraindicated by intolerance, concurrent therapies or underlying medical conditions. NSAIDs are also effective and frequently used for the management of post-operative pain. 相似文献

桉油精的抗菌抗炎作用研究 总被引：1，自引：0，他引：1
为研究桉油精的抗菌抗炎作用,选取37株奶牛子宫内膜炎临床分离株,采用二倍稀释法测定其最小抑菌浓度(MIC)及最低杀菌浓度(MBC),同时分别设计小鼠耳肿胀和腹腔毛细血管通透性增加2种炎症模型研究其抗炎活性.结果显示,桉油精对7种细菌均有抗菌作用,MIC为3.9～12.4 mg/mL,MBC为6.0 ～ 18.2 mg/mL;桉油精能够显著抑制小鼠耳肿胀及腹腔毛细血管通透性增加,并且给药剂量为400 mg/kg时效果最佳.研究表明,桉油精对奶牛子宫内膜炎致病菌具有良好的抗菌作用和显著的抗炎效果. 相似文献

The study was aimed to investigate the in vitro and in vivo efficacy of Ruxiankang injection.The Oxford cup method was took to study the antibacterial activity in vitro of Ruxiankang injection;Six classical pharmacological models which were hot plate method, acetic acid inducing writhing, xylene inducing ear edema,egg white inducing paw edema, fever in rats induced by 2,4-dinitrophenol and dried yeast were adopted to study the analgesic, anti-inflammatory and antipyretic effects of Ruxiankang injection.The results showed that Ruxiankang injection had significant inhibitory effect in vitro on Escherichia coli and Staphylococcus aureus; And among them, middle and high dose groups could extremely significantly increase the pain threshold of mice and reduce the writhing times of mice (P<0.01);Middle dose group could significantly reduce the degree of ear swelling induced by xylene and foot metatarsus swelling by egg white in mice (P<0.05);Middle and high dose groups had significant antipyretic effect caused by 2, 4-dinitrophenol fever at 1.5 to 2.0 and 3.0 to 3.5 h and dry yeast at 1.0 to 3.5 h (P<0.05).The results indicated that Ruxiankang injection could obviously inhibit Escherichia coli and Staphylococcus aureus activity and had remarkable antipyretic analgesic and anti-inflammatory effects. 相似文献

环氧合酶的两种同工酶COX-1和COX-2既是结构酶又是诱导酶,都参与了机体的某些生理和病理作用。目前已开发的环氧合酶抑制剂虽然有较好的解热镇痛等作用,但存在胃肠道或心血管等方面的不良反应,临床需根据病情合理用药。 相似文献
