introduction: memory and cognitive impairments are some of devastating outcomes of multiple sclerosis (ms) plaques in hippocampus, the gray matter part of the brain. the present study aimed to evaluate the intrahippocampal injection of ethidium bromide (eb) as a simple and focal model to assess cognition and gray matter demyelination. methods: thirty wistar rats were divided into three groups: ...

conclusions lithium intoxication should be considered in the differential diagnosis, especially in elderly patients on lithium therapy who are admitted to the emergency department with chest pain. case presentation a 62-year-old woman was admitted to the emergency department due to weakness and acute chest pain. her ecg revealed st elevation in leads di, avl and v5-6, with a ventricular rate of...

lithium is a immunomodulator that can increase immunoglobulins to confront infectious desese. it is also able to increase the production of interleukins, interferon gamma and prostaglandins. we conducted this study to evaluate the correlation between lithium consumption and humoral immunity. blood samples were obtained from 76 patients under lithium treatment. we classified the patients accordi...

Metalation of N-mesityl-P,P-diphenylphosphinic amide with nBuLi in toluene yields tetranuclear lithium N-mesityl-P,P-diphenylphosphinimidate ([Ph2P(OLi)=N−Mes]4, 1). Ph2P(O)−N(H)Mes a mixture dibutylmagnesium and butyllithium DME leads to formation dinuclear [Ph2P{OLi(dme)}=N−Mes]2 (2). Excess gives [Li(O−PPh2=N−Mes){Ph2P(=O)−N(H)−Mes}]2 (3) three-coordinate alkali ions. The metathetical approa...

Abstract Molar masses, Mark-Houwink-Sakurada (MHS) exponents, and refractive index increments (dn/dc) for three lignins were determined without derivatization by multi-detector gel permeation chromatography (GPC) in dimethylformamide (DMF) with 0.05 M lithium bromide (LiBr). The lack of effectiveness fluorescence filters on molar mass determination GPC-multi-angle laser light scattering (MALS) ...

I The pharmacokinetics of the lithium ion administered as lithium orotate were studied in rats. Parallel studies were carried out with lithium carbonate and lithium chloride. 2 No differences in the uptake, distribution and excretion of the lithium ion were observed between lithium orotate, lithium carbonate and lithium chloride after single intraperitoneal, subcutaneous or intragastric injecti...
