    The peripheral microcirculation of the lower extremity was mesured by a new laser diode (abbr. LD) dye densitometer. LD densitometer had various merits over the lamp dye densitometer, i. e., control of light direction, spatial fractionation, low power output, and less heat effect on tissues.
    The transducer was composed of two light beams, i. e., 784nm from AIGaAs LD, 940nm from GaAs light emitting diode and Si phototransistor. The signals at the site of measurment of indocyanine green by the transducer were passed through a device with pulse generating power source and amplifier, which was connected with a microcomputer by an A/D converter. The information was stored in a floppy disc. 16 patients with peripheral vascular insufficiency were tested. They were diagnosed as arterial diseases, and lymphedema. LD recordings were reproducible with greater accuracy than by the lamp dye detector. The following results were obtained: 1) The degree of peripheral insufficiency depended on the amount of dye concentration and speed of dye dilution in a given time. 2) The response to drugs (Ca2+antagonist) to improve peripheral circulation differed from cases. 3) Periodic recordings after the treatment was easy to evaluate the progress of disease.

  • LASER LITHOTRIPSY FOR BILE DUCT STONE

    Experimental and clinical studies were conducted with respect to the treatment of bile duct stones with Nd-AG laser irradiation. In the first experimental study, a total of 232 Nd-YAG laser irradiation were carried out under various conditions using 18 cholesterol stones and 7 pigment stones in order to compare the lithoclastic effect. In the second experimental study, a new ceramics (artificial sapphire) probe was used at the tip of the quartz fiber. A clinical attemp was made to crush the bile duct stones with a laser lithotripsy through percutaneous transhepatic cholangioscopy in 5 patients.
    The laser was the most effective when irradiated with the instrument in contact with the stones. The lithoclastic effect was comparable on cholesterol and pigment stones. The use of a new ceramics contact prove increased the lithoclastic effect at low output levels (12-16W per 0.5-1.0 second). In practices bile duct stones were successfully removed by transcholangioscopic laser irradiation in 5 patients without any complications.
    Bile duct stones can be effectively and safely crushed by laser irradiation at low output levels in water with the instrument in contact with the stones. In clinical application of laser irradiation, the use of jaw forceps and lithotriptors was necessary in addition.

    Laser irradiation-caused features of neuronal regrowth containing enkephalin-like immunoreactivity in the myenteric plexus around the necrosis were investigated in the guinea pig jejunum and proximal colon using an enkephalin antiserum. Carbon dioxide and Argon lasers were used for laser coagulation. The power level and irradiation time were adjusted to make a coagulation spot of about 1 mm in diameter. A distinct accumulation of immunoreactivity occurred in the laser photocoagulated ends of enkephalin neuron processes. Experimental aproaches were discussed from the standpoints of laser biology.
