A compilation of reports of biological effects and related ultrasound exposure levels can be useful in the identification of trends in effects data that may be developing in the literature. The exposures in the experiments reviewed were at frequencies used in medicine. For short (10 minutes or less) continuous wave exposure, with the exception of behavioral effects where variable results have been observed, this tabulation did not identify any in vivo or in vitro effects at spatial peak, temporal average (SPTA) intensities less than 100 mW/cm2. However, a number of effects using pulsed sources with SPTA intensities under this level have been reported. There are several frequently recurring topics in recent reports which include developmental effects and microstructure changes at the cellular level. In addition to animal investigations, there are some limited human epidemiological studies reporting an association between medical ultrasound exposure in utero and developmental effects. Although sufficient research has not been completed to draw conclusions, the findings deserve further investigation. A systematic pattern of directed research on a large scale is not apparent. The available data consist of many scattered studies conducted by individual investigators and groups throughout the world.

“…The mechanism of action described is essentially chemical and occurs probably together with inicrostraining in the lipidic membrane layer, leading to' fragmentation of the cristae. A complementary synergistic effect might be exerted by a temperature increase in the area exposed to US (II), and by ischaemia (8).…”

Experiments on the biologic effects of ultrasound (US) were carried out on rat embryos exposed for 120 s to a US beam showing features similar to those already employed for diagnostic purposes. Electron microscopic investigation of the liver parenchyma of rat embryos confirmed results obtained from adult guinea pigs with the same duration of exposure, i.e. diffuse vacuolization of cytoplasma and varying degrees of mitochondrial damage.

“…Respostas como alteração da coagulação (KORNOWSKI et al, 1994;VAEZY et al, 1998) e fibrinólise (HOGAN et al, 1982), bem como estímulo angiogênico, já têm sido descritos em situações específicas e controladas de emprego sonoro (VAEZY et al, 1999). Esta forma de energia é capaz de alcançar grandes profundidades (Tabela 2); entretanto, sabe-se que estruturas nobres e delicadas encontram-se no trajeto do feixe ultra-sônico e estão sujeitas à sua ação (HYNYNEN et al, 1996).…”

“…Seus efeitos terapêuticos têm se mostrado benéficos no tratamento de uma grande variedade de condições, como cicatrização de úlceras (DYSON & SUCKLING, 1978), estímulo à neovascularização em tecidos isquêmicos (HOGAN et al, 1982), integração de enxertos de pele total (AMANCIO et al, 2006), consolidação de fraturas e pseudo-artroses (DUARTE & XAVIER, 1983;CARVALHO & CLIQUET JR, 2003) e também na cicatrização tendinosa (SILVEIRA, 2003). O UST induz mudanças fisiológicas como ativação de fibroblasto, colágeno e diminuição de células inflamatórias por aceleração do metabolismo celular (OLSSON et al, 2006) e, quando aplicado de maneira adequada, pode reduzir a dor (STEISS & ADAMS, 1999).…”
