introduction: tetanus is a serious infectious disease and the most common cause of neonatal mortality in developing countries. although neonatal tetanus (nt) can be prevented by immunization of expectant mothers, good hygiene and asepsis during delivery, total eradication of organism is not possible. methods: the cross-sectional study was done on 480 pregnant women after delivery. data was coll...

background: recurrent spontaneous abortion (rsa) is defined as three or more se-quential abortions before the twentieth week of gestation. there are evidences to sup-port an allo-immunologic mechanism for rsa. one of the methods for treatment of rsa is leukocyte therapy; however there is still controversy about effectiveness of this method. objectives: to evaluate the effectiveness of leukocyte...

Background: Nasal continuous positive airway pressure (NCPAP) is an effective method of ventilation in newborns with respiratory distress syndrome (RDS). Using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive NCPAP. This study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal sk...

Introduction: There is no single test as a gold standard for the diagnosis of allergic rhinitis (AR). The aim of this study was to assess the usefulness and validity of nasal smear as a quick, easy and inexpensive diagnostic method for diagnosis of allergic rhinitis. Materials and Methods: This study was conducted in a university hospital setting. Nasal smears were taken from 39 patients wit...

Transcutaneous immunization (TCI) is a new technique that uses the application of vaccine antigens in a solution on the skin to induce potent antibody responses without systemic or local toxicity. We have previously shown that cholera toxin (CT), a potent adjuvant for oral and nasal immunization, can induce both serum and mucosal immunoglobulin G (IgG) and IgA and protect against toxin-mediated...

BACKGROUND We previously demonstrated that polyphosphazenes, particularly PCEP, enhance immune responses in mice immunized subcutaneously and intranasally. The objective of the present study was to investigate the efficacy of polyphosphazenes as adjuvants when delivered through different routes of vaccine administration. METHODS BALB/c mice were immunized through intranasal, subcutaneous, ora...

Streptococcus pneumoniae is a major cause of illness and death in children in developing countries. In these children, zinc deficiency is associated with an increased risk of acute respiratory tract infections, which can be reduced by daily zinc administration. Severe infections decrease zinc levels in plasma and may thereby move individuals with preexisting low zinc stores into a vicious cycle...

Amyloid beta-peptide (Abeta) appears to play a key pathogenic role in Alzheimer disease (AD). Immune therapy in mouse models of AD via Abeta immunization or passive administration of Abeta antibodies markedly reduces Abeta levels and reverses behavioral impairment. However, a human trial of Abeta immunization led to meningoencephalitis in some patients and was discontinued. Here we show that na...
