Polycyclic aromatic hydrocarbons (PAHs) were shocked across a peak shock pressure range of 5.8 to 36.6 GPa with or without serpentine and were then evaluated with an elemental analyzer, an X-ray diffractometer, a gas chromatograph, and a gas chromato

Polycyclic aromatic hydrocarbons (PAHs) with a hydrous or an unhydrous mineral matrix were impacted and analyzed, to study the behavior of PAHs against shock. Results of the shock experiments suggested that volatiles discharged from the hydrous miner

To examine the behavior of polycyclic aromatic hydrocarbons (PAHs) during shock-induced pyrolysis, we performed shock recovery experiments of various PAHs (naphthalene, anthracene, pyrene, and fluoranthene) at pressures ranging from 12.0 to 33.7 GPa.

The tissue distribution of polaprezinc (an insoluble zinc complex of L-carnosine) in rats was studied by the double tracer method using [U-14C-histidine]-, 65Zn-polaprezinc. The 65Zn-radioactivity was measured with an auto-gamma counter, and the 14C

Polaprezinc is a zinc complex of L-carnosine. Studies on the drug interaction of some antibiotics with polaprezinc in dogs were performed, because of the reported changes in the gastrointestinal absorption of some antibiotics in the presence of di- o

The disposition of polaprezinc in the rat gastrointestinal tract was studied by a double tracer method using [14C]- and [65Zn]polaprezinc. At 0·5 h after oral administration of [14C]-, [65Zn]polaprezinc to rats, the 14C-radioactivity in the gastric

The metabolic fate of L-carnosine in rats was studied after administration of [14C-U-histidine]-L-carnosine (14C-(his)-L-carnosine) or [14C-β-alanine]-L-carnosine (14C-(ala)-L-carnosine). 1. The blood level of radioactivity reached the maximum conce

Polaprezinc, an insoluble zinc complex of L-carnosine, exhibits anti-ulcer effects by acting directly on mucosal lesions. The disposition of polaprezinc in the stomach was studied to clarify the usefulness of its structure as an insoluble complex. Th
