In several countries, singing, the most accessible form of musical expression, was banned, as was the use and teaching of wind instruments. Nevertheless, innovations in music education combined with teachers' dedication and creativity introduced several elements into the teaching process which are worth using in the future.

Th2 immune responses in GATA-3-transgenic mice infected with Heligmosomoides polygyrus.

To examine the participation of transcription factor GATA-3 in Th2 immune responses in vivo, we generated transgenic mice having several copies of GATA-3 with LCK promotor. Mice were infected with the intestinal nematode Heligmosomoides polygyrus to induce Th2 immune responses. Upon antigen stimulation, IL-5 and IL-13 production of mesenteric lymph node cells from H.

Rat monoclonal anti-murine IgE antibody removes IgE molecules already bound to mast cells or basophilic leukemia cells, resulting in the inhibition of systemic anaphylaxis and passive cutaneous anaphylaxis.

IgE plays a central role in allergic reactions. Some anti-IgE antibodies (HMK-12, 6HD5) inhibit the binding of IgE to the FcepsilonRI of mast cells/basophilic leukemia cells (PT-18, RBL/2H3), but less inhibition is seen with the anti-allotypic JKS-6 and the anti-idiotypic Eb-1. Anti-IgE HMK-12 can detach bound IgE molecules from the FcepsilonRI.
