Production and functional characterization of recombinant bovine interleukin-8 as a specific neutrophil activator and chemoattractant     

Caswell JL  Middleton DM  Gordon JR 《Veterinary immunology and immunopathology》1999,67(4):327-340

Interleukin-8, a member of the chemokine family of cytokines, is a potent neutrophil chemoattractant in many non-rodent species. In this study, recombinant bovine interleukin-8 (rbIL-8) was expressed in bacteria as a glutathione-S-transferase fusion protein. The fusion protein was purified by glutathione-Sepharose affinity chromatography and recombinant rbIL-8 was eluted by cleaving with thrombin. The purified rbIL-8 molecule was approximately 8 kDa and was confirmed as authentic IL-8 by Western analysis. Recombinant bovine IL-8 induced specific dose-dependent in vitro chemotaxis of neutrophils at doses as low as 1.0 ng/ml, and this activity was inhibited by pre-treatment of rbIL-8 with a monoclonal antibody to ovine IL-8. Neutrophils exposed to rbIL-8 developed pseudopodia and became elongated as determined by microscopic analysis and flow cytometry. Injection of 3.3 ng to 3.3 microg of rbIL-8 into the skin of a normal calf induced dose-dependent recruitment of neutrophils but not eosinophils. Intravascular margination of neutrophils was obvious at the injection sites from 15 to 60 min after administration of rbIL-8, and extravascular neutrophil numbers increased steadily from 1 to 18 h after injection. Neutrophils with morphologic features of apoptosis were detected in these lesions at 18 and 30 h after injection, and this correlated with reduction in the number of dermal neutrophils. These results confirm unequivocally that bovine IL-8 functions as a neutrophil, but not an eosinophil, chemoattractant in vitro and in vivo.  相似文献

Effects of the calcium channel antagonist amlodipine in cats with surgically induced hypertensive renal insufficiency   总被引：4，自引：0，他引：4

OBJECTIVE: To determine whether amlodipine besylate decreases systemic arterial blood pressure (BP) and reduces the prevalence of complications in cats with induced hypertensive renal insufficiency. ANIMALS: 20 cats with partial nephrectomy. PROCEDURE: Following reduction in renal mass, 10 cats were administered 0.25 mg of amlodipine/kg, PO, q 24 h (group A). Ten cats served as a control group (group C). Systolic BP (SBP), diastolic BP (DBP), and mean BP (MBP), physical activity, and pulse rate were measured continuously for 36 days by use of radiotelemetric devices. RESULTS: Compared with values for clinically normal cats, SBP, DBP, and MBP were significantly increased in cats of group C. Cats in group A had significant reductions in SBP, DBP, and MBP, compared with values for cats in group C. Albuminuria but not urine protein-to-creatinine ratio was significantly correlated (R2 = 0.317) with SBP in hypertensive cats. Prevalence of ocular lesions attributable to systemic hypertension in group C (7 cats) was greater than that observed in group A (2). Two cats in group C were euthanatized on day 16 because of nuerologic complications attributed to systemic hypertension. One normotensive cat in group A was euthanatized because of purulent enteritis of unknown cause on day 27. CONCLUSIONS AND CLINICAL RELEVANCE: Amlodipine had an antihypertensive effect in cats with coexistent systemic hypertension and renal insufficiency. Its use may improve the prognosis for cats with systemic hypertension by decreasing the risk of ocular injury or neurologic complications induced by high BP.  相似文献   

Risk factors associated with development of seizures after use of iohexol for myelography in dogs: 182 cases (1998)     

Barone G  Ziemer LS  Shofer FS  Steinberg SA 《Journal of the American Veterinary Medical Association》2002,220(10):1499-1502

OBJECTIVE: To determine prevalence of seizures after use of iohexol for myelography and identify associated risk factors in dogs. DESIGN: Retrospective study. ANIMALS: 182 dogs that received iohexol for myelography in 1998. PROCEDURE: Medical records were reviewed for age, breed, sex, weight, dose and total volume of iohexol, injection site, number of injections, lesion type and location, total duration of anesthesia, duration from time of iohexol injection to recovery, presence and number of seizures, and whether surgery followed the myelogram. RESULTS: 39 (21.4%) dogs had at least 1 generalized seizure during or after myelography. Injection site was strongly associated with prevalence of seizures, and risk of seizure was significantly higher after cerebellomedullary injections, compared with lumbar injections. Mean total volume of iohexol administered to dogs that had seizures was significantly higher, compared with that administered to dogs that did not have seizures, although dosage did not differ between groups. Weight was significantly correlated with risk of seizure, and dogs that weighed > 20 kg (44 lb) had higher prevalence of seizures than dogs that weighed < 20 kg. CONCLUSIONS AND CLINICAL RELEVANCE: It is preferential to administer iohexol via the L5-6 intervertebral space to minimize the risk of seizures. Higher prevalence of seizures in large dogs, compared with smaller dogs, may be caused by administration of larger total volumes of contrast agent per volume of CSF.  相似文献   

Pathogenesis studies with Australian bat lyssavirus in grey-headed flying foxes (Pteropus poliocephalus)     

McColl KA  Chamberlain T  Lunt RA  Newberry KM  Middleton D  Westbury HA 《Australian veterinary journal》2002,80(10):636-641

OBJECTIVE: To examine the susceptibility of the grey-headed flying fox (Pteropus poliocephalus) to Australian bat lyssavirus (ABL), and to provide preliminary observations on the pathogenesis of the disease in flying foxes. PROCEDURE: Ten flying foxes were inoculated intramuscularly with ABL, and four with a bat-associated rabies virus. Inoculated animals were observed daily, and clinical samples collected every 9 to 14 days. Animals with abnormal clinical signs were euthanased, and samples collected for histological, serological, virological and immunohistological examinations. At 3 months post inoculation (PI), all survivors were euthanased, and each submitted to a similar examination. RESULTS: Three ABL-inoculated flying foxes, and two rabies-inoculated animals developed abnormal clinical signs between 15 and 24 days PI. All three ABL-inoculated animals had histological lesions consistent with a lyssavirus infection, and lyssaviral antigen was identified in the central nervous system (CNS) of each. Virus was isolated from the brain of two affected animals. Of the rabies-inoculated flying foxes, both had histological lesions and viral antigen in the CNS. Virus was recovered from the brain of only one. None of the five affected flying foxes developed anti-lyssavirus antibodies, but, by 3 months PI, five of the seven ABL-inoculated survivors, and one of the two rabies virus-inoculated survivors, had seroconverted. The dynamics of the immune responses were quite variable. CONCLUSIONS: The response of flying foxes to ABL, administered by a peripheral route of inoculation, was similar to that of bats inoculated peripherally with bat-derived rabies viruses.  相似文献
