Six to seven week old male mice of ICR strain were exposed to different doses of x-rays to determine if Jen-Sheng-Yang-Yung-Tang could be a modifier in the elimination of radiation damage. Colony forming units of bone marrow cells in the spleen (CFUs) were measured before and after x-ray irradiation with intraperitoneal injection of 10 mg/20 g or 20 mg/20 g body weight of Jen-Sheng-Yang-Yung-Tang, once a day for seven consecutive days. The recovery of CFUs and hemocytes counts by 4 Gy irradiation with Jen-Sheng-Yang-Yung-Tang administration was faster for a concentration of 20 mg/20 g than 10 mg/20 g. The measurement of 10-day CFUs showed an increase of radiotolerance in the treatment of 20 mg/20 g administration before x-ray irradiation. The injection of Jen-Sheng-Yang-Yung-Tang accelerated the recovery of hemocyte counts in mice irradiated with 4 Gy x-ray; the effect was especially profound for leukocytes with 20 mg/20 g Jen-Sheng-Yang-Yung-Tang administration after irradiation.

Results are reported for oxygen and air at 1–10 mm Hg pressure irradiated by 100-kvp X rays at about 4300 roentgens/hour. Measurement of both terms of the complex conductivity of the gas at 50 Mc/s by a bridge technique, with modulation of the X-ray source at 120 c/s, gives data on the collision frequency v, the electron density n, and the dependence of collision frequency on the electron energy u ev. The limit of sensitivity is about one electron per cc. For dry air the data agree well with recent drift tube results by Pack and Phelps represented by v(u) = 1.38 × 10−7N(air) u sec−1, where N(air) is the air density in molecules/cc. For O2 fair agreement with v(u) = 7 × 10−8N(O2)u sec−1 is observed, but the power of u may be greater than unity. The electron densities are consistent with three-body attachment of the electrons to neutral O2 molecule with the coefficient 2.8 × 10−30 cm6/sec reported by Chanin et al. for thermal electrons.

Anthropological profile in forensic context includes the assessment of parameters as ancestry, sex, age and stature of an individual by the analysis of skeletal remains. Stature can be estimated from decomposed and fully or partially skeletonized remains by means of anatomical or mathematical methods applied on the whole skeleton or single bones. Many authors calculated regression formulae for the living stature estimation by these methods, in particular based on a population similar to the remains recovered. Long bones are commonly used for stature estimation, but, when they are missing, methods involving different parts of the skeleton are needed. In this preliminary study we measured heights of the vertebral bodies in a female Caucasian Italian population, evaluated by images of morphometric X-ray absorptiometry based on dual-energy X-ray absorptiometry in living subjects investigated for routine diagnostic purposes. Thoracic and lumbar segments of the spine were measured and statistical analysis was performed, thus obtaining regression formulae for estimated living stature from thoraco-lumbar spine segments (T<sub>6</sub>-T<sub>12</sub>, L<sub>1</sub>-L<sub>4</sub> and T<sub>6</sub>-L<sub>4</sub>). We propose this method for stature evaluation in physical or forensic anthropology when the spine is available and long bones are missing.

AbstractPreliminary study of performance of an HPGe detector with an ion implanted entrance window in the spectrometry of the ultralowenergy x-rays is presented.For the first time it has been shown that almost symmetric photopeaks and absence of low energy tailing can be obtained in this region from HPGe detectors.
