The resulting serum concentrations were measured in six ewes after intramuscular administration of 10 mg/kg of gentamicin. The model providing the best fit for the experimental data was determined both by linear regression analysis between the experimental and theoretical values and by means of the Minimum Akaike Information Criterion Estimation (MAICE) test.Linear regression analysis showed certain differences favouring the monocompartmental model although the advantage was not conclusive. The MAICE test, however, permitted a clear discrimination in favour of the same model. When linear regression analysis is not conclusive, the MAICE test represents a good alternative. 相似文献

目的 探讨三黄地榆散对多重耐药铜绿假单胞菌的抑制效果,为其临床应用提供依据。方法 首先制备中药含药血清用于体外最小抑菌浓度(MIC)、最小杀菌浓度(MBC)测定。然后建立烫伤大鼠感染多重耐药铜绿假单胞菌模型,分别给予西药硫酸庆大霉素和中药三黄地榆散灌胃,正常组和模型组灌胃等容量的无菌生理盐水;在给药后的第3、7、10天检测血液中炎性细胞和炎性因子的水平。结果 体外抑菌实验显示,三黄地榆散含药血清与庆大霉素对多重耐药铜绿假单胞菌的MIC、MBC均为512 μg/mL。体内实验结果显示,与模型组比较均能显著下调大鼠血清WBC、IL-1β、TNF-α的水平(P<0.05)。结论 三黄地榆散能抑制多重耐药铜绿假单胞菌的生长,对多重耐药铜绿假单胞菌感染烫伤大鼠治疗具有较好的疗效,机制可能与调节IL-1β、TNF-α水平有关。 相似文献

Iridociliary tumors are the second most common primary ocular tumor in dogs and are usually benign. A review of the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW) database in 2009 suggested a potential correlation between malignant iridociliary epithelial tumors and ciliary body ablation by intravitreal gentamicin injection for the treatment of glaucoma. The purpose of this case series was to determine whether there is evidence of such a correlation in the COPLOW collection. Mining of the COPLOW database revealed that a significant number (39.5%) of canine globes with a history of ciliary body ablation were subsequently diagnosed with primary ocular tumors at enucleation, most commonly iridociliary epithelial tumors and melanocytic tumors. It is possible that neoplasia was present but unrecognized at the time of ciliary body ablation. These tumors had a higher than expected incidence of malignancy. These cases underscore the importance of reserving ciliary body ablation with gentamicin for disease‐free eyes. 相似文献

Five, 3-month-old mongrel dogs weighing between 4.5 to 5.5 kg were studied to evaluate and compare the efficiency of 99mTc-DTPA, 99mTc-MAG3, and 99mTc-DMSA in detecting gentamicin-induced renal tubular injury. After baseline renograms using all three methods, all dogs received daily intramuscular injections of gentamicin at a dose of 30-45 mg/kg. Additional studies were obtained after a cumulative dose of 450, 1,575, and 2,250 mg of gentamicin was reached. Glomerular filtration rate (GFR), effective renal plasma flow (ERPF), and percentage of total renal uptake measurements were calculated. Baseline and post-gentamicin injection blood urea nitrogen (BUN) and serum creatinine values were determined. A Duncan test revealed significant renal function impairment at 450 mgs of cumulated gentamicin with 99mTc-DMSA and at 1,575 mgs of cumulated gentamicin for 99mTc-DTPA and 99mTc-MAG3. There was no correlation between BUN and serum creatinine values when compared to gentamicin (p > 0.05). The images obtained with 99mTc-MAG3 were of better quality than those obtained with 99mTc-DTPA even under severe renal dysfunction. Percentage of 99mTc-DMSA uptake indicated renal damage, before than GFR and ERPF. BUN and serum creatinine measurements were poor indicators of gentamicin-induced renal failure. 相似文献
