Ectopic supernumerary tooth in nasal septum: a case study.

Introduction: Nasal teeth eruption is a rare phenomenon. The variability of symptoms and generic history makes the diagnosis difficult. This difficulty is more challenging when the tooth is placed in the depth of septum.

IgG1 and IgG2a profile of serum antibodies to Leishmania major amastigote in BALB/c and C57BL/6Mice.

It is well accepted that in experimental model of Leishmania major infection, BALB/c mice mount a Th2 response and produce IgG1 predominantly whereas C57BL/6mice enhance Th1 response with the biased production of IgG2a antibodies. Therefore, screening for parasite antigens on the basis of reactivity with sera from infected susceptible or resistant mice might be used for the identification of Th1- or Th2-inducing antigens.In this study, the antigenic profile of Leishmania major amastigote that induce IgG1 or IgG2a isotypes in infected BALB/c or C57BL/6 mice were compared.
