In induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (MALT) M cells. In this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid TT and CpG-ODN encapsulated within PLGA nanos...

BACKGROUND Peroxisome proliferator-activated receptor γ (PPAR-γ) has been shown to play an important role in the control of inflammatory responses acting on macrophages, mast cells, T cells, and eosinophils. The present study was aimed at investigating the effects of PPAR-γ agonist on nasal symptoms and eosinophil accumulations in nasal mucosa by using a murine allergic rhinitis model. Furtherm...

OBJECTIVE To evaluate whether a nasal gel, administrated using a radial-hole inhaler, reaches the olfactory cleft and if a different administration method influences distribution. MATERIAL AND METHOD Sixteen healthy volunteers underwent a nasal endoscopy at 1 and 7minutes after the administration of a intranasal gel, with a different method in each fossa. RESULTS No dye deposition was ident...

The aim of this review is to provide an understanding of the anatomical and histological structure of the nasal cavity, which is important for nasal drug and vaccine delivery as well as the development of new devices. The surface area of the nasal cavity is about 160 cm2, or 96 m2 if the microvilli are included. The olfactory region, however, is only about 5 cm2 (0.3 m2 including the microvilli...

Recent studies of several animal models have shown beneficial effects of probiotics against allergic responses. However, few reports have examined the effects of probiotics on allergic nasal symptoms such as sneezing and nasal obstruction in animal models of allergic rhinitis. This study evaluated the efficacy of Bifidobacterium bifidum G9-1 (BBG9-1) on antigen-induced nasal symptoms using guin...

discussion while this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. theref...
