Charakteristisch
Deliquescent and oxidizing. Hazardous chemicals. Human inhalation of lanthanum and its compounds fume can cause headache, nausea and other symptoms, and even lead to death in severe cases. Lanthanum nitrate has combustion-supporting properties, and it is an explosive product.
Verwenden
Starting material for the electrochemical synthesis of a LaMnO3 thin film coating on stainless steel substrates.1 A novel solvothermal process for formation of doped lanthanide oxysulfide, La2O2S, was developed in order to advance possible applications of this material in phosphors, fluorescent display tubes or heat transfer measurement.2
Verwenden
Lanthanum(III) nitrate hydrate serves as a raw material for the electrochemical synthesis of LaMnO4, which is a thin film coating on stainless steel substrate. It is also used in preparation of La2O2S. Further, it is used in phosphors, fluorescent display tubes and heat transfer measurement.
Biologische Aktivität
Low-dose excitatory effect of lanthanum nitrate on learning and memory in mice and its relationship with phosphorylation levels of cAMP response element binding protein (CREB) and Jun-amino-terminal kinase (JNK) proteins. ICR mice were exposed to 0.002, 0.02, 0.2, 2, and 20 mg/kg lanthanum nitrate for 4 weeks, and the reaction time and the number of errors in the water maze were measured every day. The content of p-CREB and p-JNK was determined. [Results] The reaction time of the water maze of mice showed a trend of shortening gradually and then gradually increasing with the increase of the dose at the 4th week of exposure. The reaction time of the 0.2 mg/kg group was the shortest; while the number of errors appeared Contrary to the trend, the 2mg/kg group had the least number of errors. The phosphorylation levels of CREB (6.20±3.2) and JNK (4.11±2.92) in the hippocampus of mice in the 0.2 mg/kg dose group were increased after oral exposure to lanthanum nitrate for 4 weeks. Compared with the solvent control group, the difference was significant. sex. There was no significant difference in cortical CREB and JNK phosphorylation in mice exposed to different doses of lanthanum nitrate compared with the control group. Oral exposure to lanthanum nitrate can increase the phosphorylation levels of CREB and JNK proteins in the hippocampus of mice, which is consistent with the trend of changes in the learning and memory ability of mice, suggesting that low-dose lanthanum nitrate may induce the phosphorylation levels of learning-related proteins by increasing the level of phosphorylation. It can promote the spatial learning and memory of mice.
