Two experiments were performed in vitro with human sperm from a panel of 11 donors. In both experiments, washed sperm from each donor were divided into four equivolume samples, three of which were resuspended in various formulations of Tyrode's solut

Kidneys from rabbits and dogs were perfused with one of several DMSO concentrations (0.0, 0.7, 1.4, 2.1 m ) in a K + -Mg 2+ -rich perfusate, frozen, and then thawed with equipment providing electromagnetic (EM) illumination. Electrical properties (di

Equipment was designed and fabricated for uniformly thawing frozen canine kidneys using single-frequency electromagnetic radiation. Complete and uniform warming of frozen kidneys from −70 to +14 °C over periods ranging from 1.5 to 4.5 min was achi

The [K+]/[Na+] ratio of rabbit renal cortical slices was used to examine, at 25 degrees C, the effects on viability of three cryoprotectant agents (CPA) (dimethyl sulfoxide (Me2SO), ethylene glycol, and glycerol) in combination with three vehicle sol

Summary Rat hearts were perfused with a balanced salt solution, cooled at one of several rates (1°C/min; 70°C/sec; 250°C/sec) and, by using freeze-substitution preparative techniques, were studied by light and electron microscopy for ice crystal s

Rabbit kidneys were perfused at 37 °C with various concentrations of DMSO in a K + -Mg 2+ -rich perfusate. The effects of DMSO on various functional parameters of the rabbit kidney perfused for 60 min were compared with the functional effects of per

Isolated rabbit kidneys were perfused at 37 ° C with a cell-free solution containing 0.0, 1.4, 2.1, and 2.8 m DMSO for 60 min. Electron microscopic examination of cortical structures revealed relatively high sensitivity of proximal tubular cells to

Solution based on disodium glycerophosphate have been assessed for ability to inhibit cellular swelling during hypothermic storage of slices of rabbit renal cortex. It was found that slices stored in glycerophosphate media for 3 days gained about 50%

The rationale for using electromagnetic heating techniques, such as in the microwave frequency range (2450 MHz), to thaw large organs after cryopreservation is that this technique, in contrast to numerous others, has been shown to yield functioning d
