The effect of High energy shock waves (HESW) on human bone marrow
Urological Research, 1988The effect of High energy shock waves (HESW) on the viability and proliferation of normal human bone marrow cells was evaluated. A dose dependent increase in cytotoxicity with an increase in the number of HESW was demonstrated. In general 700 HESW immediately reduced the cell viability of bone marrow cells by 50%.

High Energy Shock Waves Suppress Tumor Growth in Vitro and in Vivo
Journal of Urology, 1986Exposure of the Dunning R3327AT-3 rat prostatic carcinoma and SK-Mel-28 human melanoma, in vitro, to high energy shock waves resulted in a reduction in cell viability as determined by trypan blue exclusion and a decrease in the number of colonies formed in a clonogenic assay.

High-energy shock waves pyrotherapy. A new concept in extracorporeal tumour therapy
Surgical Oncology, 1993High-intensity shock waves (HISW) waves can produce rapid and intense tissue heating. We have studied a novel device capable of simultaneous shock wave generation, focusing and extracorporeal delivery along with imaging of the proposed target. Shock waves are generated by piezo-electric crystals and target a focal point of 10 x 2 mm.

Free Radical Production by High Energy Shock Waves-Comparison With Ionizing Irradiation
Journal of Urology, 1988Fricke chemical dosimetry is used as an indirect measure of the free radical production of ionizing irradiation. We adapted the Fricke ferrous sulfate radiation dosimeter to examine the chemical effects of high energy shock waves. Significant free radical production was documented.

Optical imaging of shock waves produced by a high-energy electromagnetic transducer
Physics in Medicine and Biology, 1993An electromagnetic acoustic transducer (EMAT) and acoustic lens have been constructed to provide reproducible and well characterized acoustic shock waves in water. The peak pressure amplitude variation for the unfocused and focused shock waves was found to be within +/- 5%.

High-Energy Shock Waves Alter Cytosolic Calcium Mobilization in Single MDCK Cells
Nephron, 1998The damaging effect of shock waves on intracellular calcium homeostasis in renal tubular cells has not been investigated previously. We have examined the effects of shock waves on Madin Darby canine kidney (MDCK) cells by determining the release of two cellular enzymes: glutamate oxalactate transferase (GOT) and lactate dehydrogenase (LDH); and both ...

In vitro investigations on cellular damage induced by high energy shock waves
Ultrasound in Medicine & Biology, 1992Single-cell suspensions of the prostate carcinoma cell line PCA were exposed to electromagnetically generated ultrasound shock waves (source and focusing lens identical to those used in the commercially available lithotripor Lithostar Plus). Cell loss of up to 40% occurred in sample tubes containing air.

High energy focused shock wave therapy accelerates bone healing
Veterinary and Comparative Orthopaedics and Traumatology, 2015SummaryObjectives: To evaluate the influence of shock wave therapy (SWT) on radiographic evidence of bone healing after tibial plateau leveling osteotomy (TPLO).Methods: Healthy dogs between two to nine years of age that underwent TPLO were randomly assigned to receive either electro- hydraulic SWT (1,000 shocks) or sham treatment (SHAM).

Production of High-Energy Plasmas by Magnetically Driven Shock Waves
Physical Review, 1957High-voltage discharges (5-100 kilovolts) with peak currents in 0.3 to 5 microseconds have been used to produce shock waves in deuterium plasmas. The discharge is struck in a transverse magnetic field and the resultant Lorentz force drives the plasma out of the region of the discharge into a quartz side arm.

High-energy shock waves induce blood flow reduction in tumors.
Cancer research, 1993We have studied the effect of extracorporeally applied high-energy shock waves (HESW) on blood flow in amelanotic melanomas (A-Mel-3). Two tumors were implanted in the dorsal skin of 21 Syrian golden hamsters. One of the tumors was treated with 200 HESW, and the other served as an intraindividual control.
