[IR absorption spectral characteristics of chicken bile].

It has been proved by medicinal practice that the extraction from chicken bile has excellent antiphlogistic and anti-tumour effects. Chicken bile and the biles of various animals were dried and after IR spectral analyses, different IR spectra can be obtained with the resulting powders. In comparison with IR spectra, the IR spectrum from chicken bile is significantly different with that of other animals; whereas there are very good consistency among the chicken biles from different origin samples.

Laser vaporization on intracranial tumors.

Brain tumors can be treated with the laser. The CO2 laser may be used in several ways. Massive or well-encapsulated tumors may be removed in the usual way and the remnant vaporized by the laser from the depth, dura, or cranium.
