1. Swine influenza virus obtained from the lungs of infected ferrets or mice, when administered intramuscularly or subcutaneously, immunizes swine to swine influenza. 2. Ferrets, which have received subcutaneous injections of swine influenza virus obtained from the lungs of infected ferrets, are immune to intranasal infection with this virus. Similar injections with virus from the lungs of infe...

BACKGROUND No studies to date have compared mouse models of asthma by evaluating airway histopathology. OBJECTIVE To compare 2 such models by studying chronic histopathologic changes of the airways using light and electron microscopy. METHODS Twenty-one male BALB/c mice were divided into 3 groups: a nebulization group sensitized via an intraperitoneal injection of 10 microg ovalbumin on day...

Background and aims. There are several known sedative drugs, with midazolam and ketamine being the most commonly used drugs in children. The aim of this study was to compare the effect of intranasal and oral midazolam plus ketamine in children with high levels of dental anxiety. Materials and methods. A crossover double-blind clinical trial was conducted on 23 uncooperative children aged 3-6 (n...

Although the intranasal administration of peptides containing T cell epitopes has been shown to be a potent method of inhibiting responses to the allergen Der p 1, the experiments to date have concentrated on their ability to regulate immune responses to the injection of antigen in a T(h)1-type adjuvant. Their ability to regulate responses to a T(h)2-type immunization and to sensitization via t...

Olfactory ensheathing cells (OECs) play an important role in the continuous regeneration of the primary olfactory nervous system throughout life and for regeneration of olfactory neurons after injury. While it is known that several individual OEC subpopulations with distinct properties exist in different anatomical locations, it remains unclear how these different subpopulations respond to a ma...

introduction: preoperative psycho emotional preparation of patients is one of the principle purposes of anesthesia which can be achieved by administration of premedications. children should receive premedication before entering the operating room due to their dependence on parents and the fear and anxiety of separation from parents. different drugs are administered for this purpose, but conside...

OBJECTIVE Treatment of severe hypoglycemia with loss of consciousness or seizure outside of the hospital setting is presently limited to intramuscular glucagon requiring reconstitution immediately prior to injection, a process prone to error or omission. A needle-free intranasal glucagon preparation was compared with intramuscular glucagon for treatment of insulin-induced hypoglycemia. RESEAR...

Local injections of various materials to the face have become increasingly popular for cosmetic purposes. These procedures can cause serious adverse effects if they are not done properly or if they are performed with improper materials. Embolic arterial occlusion is rare but can be a devastating complication after injection in the facial area. Here we report multiple embolic occlusions involvin...

Nude (Nu/Nu) and heterozygous (NU/+) mice were infected with Actinomyces israelii serotype I by either intranasal instillation or intravenous injection. Lung clearance data and 50% lethal dose values indicated that T-lymphocytes were not necessary for pulmonary clearance or prevention of systemic actinomycosis. However, T-lymphocyte deficiency may play a role in the localized cervicofacial form...

Background: Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is an infectious zoonotic pathogen causing human infections. These infections, in some cases, can lead to hemolytic uremic syndrome and its life-threatening complications and even death worldwide. The first intimate bacterial adhesion, intimin (I), with its own receptor translocated intimin receptor (Tir) and E. coli secreted protein...
