Effect of High Energy Shock Waves on Human Spermatozoa in vitro

European Urology, 1988
We investigated the effect of high energy shock waves on human spermatozoa in vitro. Human semen samples of proven motility, kept in polyethylene tubes, were subjected to shock waves (100, 500, and 1,000) using a HM3 Dornier lithotripter. A progressive decrease in the spermatozoa vitality was observed with increasing doses of shock waves.

Effects of High-Energy Shock Waves on Testes of Wistar Rats

Journal of Endourology, 1993
The effects of high-energy shock wave (HESW) on testes are still unknown. We investigated Wistar rats at 3 months of age for morphologic and functional changes in the testes and in serum follicle-stimulating hormone (FSH), progesterone (Prog), and testosterone (T).

Effects of high-energy shock waves onmurine renal cell carcinoma

Urology, 1991
The effects of high-energy shock waves (HESW) on a murine renal cell carcinoma (RenCa) was investigated. In vitro exposure of tumor cells to HESW resulted in a dose-dependent reduction in cell viability as determined by trypan blue dye exclusion, plating efficiency, growth curve, and soft agar clonogenic assays.

The effect of High energy shock waves (HESW) on human bone marrow

Urological Research, 1988
The 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, 1986
Exposure 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.

Cellular Effects of Piezoelectric Versus Electrohydraulic High Energy Shock Waves

Journal of Urology, 1992
High energy shock waves produced by a piezoelectric lithotripter, (EDAP LT.01) and an electrohydraulic lithotripter, (Dornier HM3) were examined for their effects on Chinese hamster ovary cells in suspension. The EDAP caused acute lactate dehydrogenase release, consistent with severe membrane disruption in a proportion of cells, with the remaining ...

In vitro investigations on cellular damage induced by high energy shock waves

Ultrasound in Medicine & Biology, 1992
Single-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.

Optical imaging of shock waves produced by a high-energy electromagnetic transducer

Physics in Medicine and Biology, 1993
An 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 Wave Treatment of Femoral Head Necrosis in Adults

Clinical Orthopaedics and Related Research, 2001
Adults with Stages I to III osteonecrosis of the femoral head present an overall therapeutic challenge. The objective of the current prospective study was to show the effectiveness of high-energy shock wave therapy in treatment of patients with Association Research Circulation Osseous Stage I to Stage III necrosis of the femoral head by assessing ...

Application of High Energy Shock Waves to Single Cells

1989
Extracorporeal shock wave lithotripsy has been in clinical use since 1980 with several hundred thousand patients treated to date. Striking complications, like perirenal hematomas, are rare with a range of approximately 0.5%–1.5%. High dose applications in pigs and dogs have shown devastating effects on renal parenchyma with intrarenal hemorrhage and ...
