The observation of unusual specimens induces one to suggest that, in vivo, the cilia of the hair cells are deeply immersed in the tectorial membrane. The cilia show their terminal parts free only when, due to fixation effects, they are drawn out from the tectorial membrane. This relationship induces one to reconsider the modality of excitement of the cochlear receptors.

Ten workers struck by the same blast of an explosion were selected for a comparative study: 5 patients were treated with low molecular weight dextran, 5 patients were left without treatment. Recovery from the inner ear damage, measured by the restoration of hearing losses (bone conduction threshold), proved significantly better in the treated group. This result supports the concept that microcirculatory disturbances in the cochlea play an important role in the pathogenesis of permanent hearing loss after exposure to damaging noise intensities.

In conclusion, it may be said that congenital toxo-plasmosis as a cause of deafness is unlikely in man; it could not be said to be impossible. Acceptable criteria for such a diagnosis are difficult to see [Wright, 1971]. Low antibodies in the mother might be a factor in favour of transmission; high antibodies and evidence of infection during the relevant pregnancy would most likely lead to a classical case of congenital toxoplasmosis resulting in foetal death, or an infant living with many defects. Such a case would of course present little difficulty, and KELEMEN’s [1958] cases were presumably in this group. In the present experimental study no lesions were produced in the bulla or cochlea in guinea-pigs.

Based on ultrastructural evidence of the interdental cells from guinea pig, cat and human the authors suggest that the function of interdental cells is to take up a material from the spiral limbus by pinocytosis and transport it via the vesicular channels of the endoplasmic reticulum to the Golgi apparatus until it is secreted into the tectorial membrane.
