The respiratory epithelium is the only tissue of the adult mouse that is uniformly susceptible to influenza virus infection. The virus is most effective when administered intranasally"' although pulmonary lesions can be produced less regularly by direct intrathoracic inoculation.' Rickard and Francis'8 were the first to demonstrate virus multiplication and pulmonary consolidation after parenter...
We addressed the question how long salivary oxytocin levels remain elevated after intranasal administration, and whether it makes a difference when 16 or 24 IU of oxytocin administration is used. Oxytocin levels were measured in saliva samples collected from 46 female participants right before intranasal administration (at 9:30 a.m.) of 16 IU (n = 18) or 24 IU (n = 10) of oxytocin, or a placebo...
To establish whether allergic asthma could be induced experimentally in a nonhuman primate using a common human allergen, three female rhesus monkeys (Macaca mulatta) were sensitized with house dust mite (Dermatophagoides farinae) allergen (HDMA) by subcutaneous injection, followed by four intranasal sensitizations, and exposure to allergen aerosol 3 hours per day, 3 days per week for up to 13 ...
Vesicular stomatitis virus (VSV) is the prototype virus for 75 or more negative-strand RNA viruses in the rhabdovirus family. Some of these viruses, including VSV, can cause neurological impairment or death upon brain infection. VSV has shown promise in the prevention and treatment of disease as a vaccine vector and an oncolytic virus, but infection of the brain remains a concern. Three VSV var...
Following the intraperitoneal inoculation of mice with large doses of epidemic influenza virus (50,000 to 1 million intranasal M.L.D.) it can be recovered from the lungs in high concentration, and pulmonary lesions of moderate extent may be observed. The virus reaches its highest titer in the lungs 48 to 72 hours after intraperitoneal injection and may persist for 10 days. Virus may be recovere...
BACKGROUND Melatonin is traditionally administered orally but has a poor and variable bioavailability. This study aims to present an overview of studies investigating the pharmacokinetics of alternative administration routes of melatonin. METHODS A systematic literature search was performed and included experimental or clinical studies, investigating pharmacokinetics of alternative administra...
The therapeutic potential of adult neural stem cells (aNSCs) has been shown in EAE, an animal model of MS, administered by either i.c.v. or i.v. injection. However, i.c.v. is an invasive approach, while the i.v. route of aNSCs is associated with a non-specific immune suppression in the periphery. Here we demonstrate that intranasal (i.n.) delivery of fluorescently labeled aNSCs resulted in thei...
The current studies were aimed at evaluating the efficacy of intranasal pentoxifylline (Ptx) pretreatment in protecting mesodopaminergic system and hippocampus from oxidative damage of lithium-pilocarpine induced status epilepticus (SE) and the involvement of nuclear factor erythroid 2-related factor 2- (Nrf2-) antioxidant response elements pathway. Pentoxifylline was administered to rats intra...
Objective- This study aimed to compare sedation efficacy in intranasal administration of xylazine, diazepam and midazolam with or without ketamine in Chough. Design- To determine the sedation efficacy, an experimental in vivo study was employed. Animals- Seven healthy Choughs were examined in the current study. Procedu...
The use of protein antigens able to protect against the majority of Streptococcus pneumoniae serotypes is envisaged as stand-alone and/or complement to the current capsular polysaccharide-based pneumococcal vaccines. Pneumolysin (Ply) is a key virulence factor that is highly conserved in amino acid sequence across pneumococcal serotypes, and therefore may be considered as a vaccine target. Howe...
