This study evaluated the DNA damage caused by repeated doses of xylazine-ketamine and medetomidine-ketamine anesthesia in the liver and kidneys.
In this study, 60 rats were used. The rats were divided into group 1 (xylazine-ketamine), and group 2 (medetomidine-ketamine), and these anesthetic combinations were administered to the rats at repeated doses with 30-min intervals. The effects of these anesthetic agents on the tumor necrosis factor-alpha gene for DNA damage were investigated.
According to the gene expression results, it was observed that a single dose of xylazine-ketamine was 2.9-fold expressed, while first and second repeat doses did not show significant changes in expression levels. However, in the case of the third repetition, it was observed to be 3.8-fold overexpressed. In the case of medetomidine-ketamine administration, it was observed that a single-dose application resulted in a 1.04-fold expression, while the first and the third repeat doses showed a significant down expression. The samples from the second repeat dose administration group were found to have insignificant levels of expression.
This study can contribute to understanding the safe anesthetic combination in research and operations in which xylazine-ketamine and medetomidine-ketamine combinations are used.
本研究评估了重复给予二甲噻嗪-氯胺酮和甲磺酸右美托咪定-氯胺酮麻醉后对肝脏和肾脏造成的 DNA 损伤。
本研究使用了 60 只大鼠。将大鼠分为第 1 组(二甲噻嗪-氯胺酮)和第 2 组(甲磺酸右美托咪定-氯胺酮),以 30 分钟的间隔重复给予这些麻醉组合。研究了这些麻醉剂对肿瘤坏死因子-α基因造成的 DNA 损伤的影响。
根据基因表达结果,观察到单次给予二甲噻嗪-氯胺酮时表达增加了 2.9 倍,而第一次和第二次重复剂量时表达水平没有明显变化。然而,在第三次重复时,表达水平增加了 3.8 倍。在给予甲磺酸右美托咪定-氯胺酮时,单次给药导致表达增加了 1.04 倍,而第一次和第三次重复剂量则显示出明显的下调。第二次重复剂量给药组的样本表达水平无显著差异。
本研究有助于理解在研究和手术中安全使用二甲噻嗪-氯胺酮和甲磺酸右美托咪定-氯胺酮组合的麻醉方法。
