1. On noise and hearing loss : Prevalence and reference data
Abstract : Noise exposure is one of the most prevalent causes of irreversible occupational disease in Sweden and in many other countries. In hearing conservation programs, aimed at preventing noise-induced hearing loss, audiometry is an important instrument to highlight the risks and to assess the effectiveness of the program.

2. Pitch, loudness and frequency selectivity in low-frequency hearing loss
Abstract : Patients with Ménière's disease and cochlear hydrops show fluctuating low-frequency hearing loss (FLFHL). At present these changes are followed as patients' subjective reports and occasional measurements. READ MORE

3. Functions of platelet-derived growth factor-A during organogenesis
Abstract : The formation of organs during embryonic development is calledorganogenesis. This process is regulated by the genes residing in the genome. READ MORE

4. A functional genomics approach to PDGF and pericyte biology
Abstract : The rapid expansion of genome sequence data demands for increased efforts and speed concerning functional analysis of gene products. Two approaches to such analysis, namely transgenic technologies and analysis of gene expression have successfully been used to study functions of gene products in complex organisms, such as mammals.

5. Hair cell and organ of corti responses to normal and intense acoustic stimulation
Abstract : The principal aims of the studies described in this thesis were to develop an in vitro model for studying acoustic overstimulation at the cellular level, to define the electrical and mechanical response characteristics of the perfused temporal bone preparation, and to investigate the effects of intense sound stimulation on the calcium levels of the hair cells in the intact hearing organ. In the in vitro model for acoustic overstimulation, isolated cochlear outer hair cells were subjected to a pressure jet emanating from a glass micropipette aimed at the cell body. READ MORE
