Serum C-reactive protein concentration as an indicator of remission status in dogs with multicentric lymphoma

BACKGROUND: The acute-phase protein C-reactive protein (CRP) is used as a diagnostic and prognostic marker in humans with various neoplasias, including non-Hodgkin's lymphoma. OBJECTIVE: To evaluate if CRP could be used to detect different remission states in dogs with lymphoma. ANIMALS: Twenty-two dogs with untreated multicentric lymphoma. METHODS: Prospective observational study. Blood samples were collected at the time of diagnosis, before each chemotherapy session, and at follow-up visits, resulting in 287 serum samples. RESULTS: Before therapy, a statistically significant majority of the dogs (P = .0019) had CRP concentrations above the reference range (68%, 15/22). After achieving complete remission 90% (18/20) of the dogs had CRP concentrations within the reference range, and the difference in values before and after treatment was statistically significant (P < .001). CRP concentrations of dogs in complete remission (median, 1.91; range, 0.2-103) were significantly different (P = .031) from those of dogs with partial remission (median, 2.48; range, 0-89), stable disease (median, 1.77; range, 1.03-42.65), or progressive disease (median, 8.7; range, 0-82.5). There was profound variation of CRP measurements within each dog. CONCLUSIONS: CRP is useful in determining complete remission status after treatment with cytotoxic drugs. However, the individual variation between dogs means CRP concentration is not sufficiently different in other remission states to permit its use in monitoring progression of the disease. Greater reliability in determining remission status might be achieved by combining CRP concentration with other serum markers.  相似文献

为了筛选出对温室白粉虱高效的农药复配组合,本试验选择9种杀虫单剂对田间采集的温室白粉虱进行了毒力测定,并利用共毒因子和共毒系数对氟吡呋喃酮与8种杀虫剂复配组合的联合毒力进行评价,同时对筛选出的药剂进行田间药效试验。结果表明：杀虫单剂毒力测定中,LC₅₀最低的为鱼藤酮,最高的为螺虫乙酯,48 h LC₅₀分别为0.43μg/mL和78.59μg/mL;毒力大小顺序为鱼藤酮>氟啶虫胺腈>除虫菊素>苦参·印楝素>d-柠檬烯>氟吡呋喃酮>啶虫脒>高效氯氰菊酯>螺虫乙酯。共毒系数大于120的复配组合为氟吡呋喃酮与d-柠檬烯5∶1、氟吡呋喃酮与苦参·印楝素1∶2和1∶5,共毒系数分别为268.31、247.80和241.46,LC₅₀分别为5.76、4.51μg/mL和4.34μg/mL。氟吡呋喃酮与d-柠檬烯5∶1复配增效作用明显,为最佳配比。田间药效试验表明,10 d后,17%氟吡呋喃酮可溶液剂与1%苦参·印楝素乳油、5%d-柠檬烯可溶液剂复配对温室白粉虱的防效达到83.5%～83...  相似文献

【目的】研究N,O-羧甲基壳聚糖对鸡的急性毒性,评价该药的安全性;【方法】以最大浓度的N,O-羧甲基壳聚糖(10.5%),按20ml/(kg·bw)(2.1g/(kg·bw)/次)剂量24h内给鸡灌服;【结果】给药后连续观察7天,各组试验鸡全部存活,临床、剖检均未见到异常变化,测不出LD50,根据新药审批办法中关于急性毒性的要求,进行最大耐受量的测定。鸡灌服给予N,O-羧甲基壳聚糖的最大耐受量为10.5g/(kg·bw),相当于临床拟用量的3500倍;【结论】N,O-羧甲基壳聚糖毒副作用很小,临床可以安全应用。  相似文献   

铝盐对厌氧微生物产甲烷活性的影响研究

废水中铝盐含量增高以及铝盐的生物毒性使其对废水生物处理工艺中微生物产生的危害引起了人们的关注。本文以产甲烷活性为指标，通过投加氯化铝测定其对颗粒污泥的产甲烷毒性来研究铝盐对厌氧菌的危害。结果表明，铝盐使厌氧颗粒污泥的活性明显降低，但其毒性可以驯化，且清除铝盐后厌氧颗粒污泥的活性可以恢复。  相似文献
