Abstract There is still little literature data on the toxicity and safety of the commonly used molybdenum (Mo) disulfide which is present in the working as well as living environments. Thus, an experiment was carried out involving rats, with single and repeated intratracheal exposure (in the latter case, 7 administrations at 2-week intervals with the analysis performed after 90 days) to lower (1.5 mg Mo kg −1 b.w.) and higher (5 mg Mo kg −1 b.w.) doses of molybdenum(IV) sulfide nanoparticles (MoS 2 -NPs) and microparticles (MoS 2 -MPs). The analysis of Mo concentrations in the tail and heart blood as well as in soft tissues (lung, liver, spleen, brain), after mineralization and bioimaging, was meant to facilitate an assessment of its accumulation and potential effects on the body following short- and long-term exposure. The multi-compartment model with an exponential curve of Mo concentration over time with different half-lives for the distribution and elimination phases of MoS 2 -MPs and MoS 2 -NPs was observed. After 24 h of exposure, a slight increase in Mo concentration in blood was observed. Next, Mo concentration indicated a decrease in blood concentration from 24 h to day 14 (the Mo concentration before the second administration), below the pre-exposure concentration. The next phase was linear, less abrupt and practically flat, but with an increasing trend towards the end of the experiment. Significantly higher Mo concentrations in MoS 2 -NPs and MoS 2 -MPs was found in the lungs of repeatedly exposed rats compared to those exposed to a single dose. The analysis of Mo content in the liver and the spleen tissue showed a slightly higher concentration for MoS 2 -NPs compared to MoS 2 -MPs. The results for the brain were below the calculated detection limit. Results were consistent with results obtained by bioimaging technique.
摘要目前，关于常用的二硫化钼(Mo)在工作和生活环境中的毒性和安全性的文献资料还很少。因此，对大鼠进行了一项实验，通过单次和多次气管内暴露(后者为7次，间隔2周，90天后进行分析)，以降低(1.5 mg Mo kg - 1 b.w)和更高(5 mg Mo kg - 1 b.w)剂量的钼(IV)硫化钼纳米颗粒(MoS 2 -NPs)和微粒(MoS 2 -MPs)。矿化和生物成像后，对尾血和心脏血液以及软组织(肺、肝、脾、脑)中的Mo浓度进行分析，旨在促进评估其积累和短期和长期暴露后对身体的潜在影响。观察到Mo 2 -MPs和Mo 2 -NPs的分布和消除相具有不同半衰期Mo浓度随时间的指数曲线的多室模型。暴露24 h后，血液中Mo浓度略有升高。其次，Mo浓度显示血药浓度从24小时到第14天(第二次给药前的Mo浓度)下降，低于暴露前的浓度。下一阶段是线性的，不那么突然，几乎是平坦的，但在实验结束时有增加的趋势。与单次暴露大鼠相比，反复暴露大鼠肺部的MoS 2 -NPs和MoS 2 -MPs中的Mo浓度明显较高。肝脏和脾脏组织Mo含量分析显示，MoS 2 -NPs的浓度略高于MoS 2 -MPs。对大脑的检测结果低于计算出的检测限。结果与生物成像技术结果一致。

Abstract One of the commoly used chemotherapeutic agents is 5-Fluorouracil (5-FU). Unfortunately, the clinical administration of 5-FU is complicated with serious cardiotoxic effects and the safe use becomes an urgent task in cardio-oncology. Till now, there are no studies discussed the role of empagliflozin (EMP) against 5-FU cardiotoxicity. Thus, we investigated this effect and the involved mechanisms in 5-FU induced heart injury. Forty male rats of Wistar albino species were used and divided randomly into four groups. Group I is the control group, group II is EMP given group, group III is 5-FU cardiotoxic group and group IV is 5-FU plus EMP group. 5-FU (150 mg/kg) was administered as a single intraperitoneal (i.p.) dose on 1st day to induce cardiotoxicity with or without EMP (30 mg/kg/d) orally for 5 days. The dose of 5-FU is relevant to the human toxic dose. Our data showed that 5-FU given group caused cardiotoxicity with significant increase of serum cardiac enzymes, toll like receptors, enhancement of nuclear factor kappa B (NF-κB), interleukin1β (IL1β), IL6, myeloid-differentiation-factor 88 (MYD88), heart weight, malondialdehyde (MDA), tumor-necrosis-factor-alpha (TNFα), sodium glucose co-transporter 2 (SGLT2), P53 and caspase3 expression with clear histopathological features of cardiotoxicity. Moreover, there is a significant decrease in reduced glutathione (GSH) and total antioxidant capacity (TAC). Interestingly, co-administration of EMP could ameliorate 5-FU induced biochemical and histopathological changes. This effect may be due to modulation of SGLT2, decreasing inflammation, oxidative stress and apoptosis with downregulation of an essential inflammatory cascade that mediates 5-FU cardiotoxicity; TNFα/TLR/NF-κB.
