Abstract: Dehydroepiandrosterone (DHEA) has an immune response regulating effect in vertebrates to protect from morbid effect of infection and immune suppressive therapies. DHEA is also effective for use in treatment of alopecia. Protection results from a generalized host response.

Abstract: The steroid hormone dehydroepiandrosterone (DHEA), when administered by feeding or by subcutaneous injection, significantly improves the host response to viral infection. Experimental animal data shows that, with infection (100,000 plaque forming units/animal) of a human coxsackievirus B4 strain, which causes mortality in about 90% of infected animals, mortality was reduced to 37% when animals were treated with DHEA. Moreover, DHEA induced an 80% elevation in the number of antibody forming cells, particularly in cells forming gamma globulin M (early antibodies), and gamma globulin G (secondary antibodies). This elevation in the number of antibody forming cells was evident only in DHEA treated and virus infected animals, but not in uninfected animals treated with DHEA or in infected animals not treated with DHEA. In virus infected and DHEA treated animals there was also an elevation in the number of monocyte cells, the particular white blood cell associated with a resistance to this infection.

Abstract: A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone conduction. The hearing is believed to use channels of communications to the brain that are not normally used for hearing. These alternative channels do not deteriorate significantly with age as does the normal hearing channels. The supersonic bone conduction frequencies are discerned as frequencies in the audiometric range of frequencies.

Abstract: A method for treating the skin and/or scalp of a human host by the administration of a melatonin composition in order to improve the cosmetic or physical appearance of the skin and/or scalp, and the compositions therefore.
