Inhalation pharmacokinetics of dichlorofluoromethane (CFC 21) and chlorodifluoromethane (CFC 22) were studied in male Wistar rats by use of a closed inhalation chamber system. CFC 21 was readily eliminated via metabolism. However, CFC 22 underwent no detectable metabolism; pretreatment of

Complexes of haloforms of the type HCCl(n)F(3-)(n) (n = 1-3) with dimethyl ether have been studied in liquid argon and liquid krypton, using infrared spectroscopy. For the haloform C[bond]H stretching mode, the complexation causes blue shifts of 10.6 and 4.8

The minimum ambient partial pressure required to reversibly disrupt conducted responses in myelinated nerve fibers (Pblock) was determined for 11 gases and chloroform. For all but one substance, Pblock was inversely proportional to their nonaqueous solubility; large-diameter fibers were less

Sixty-one mandibular molar teeth with clinically manifest pulpitis, which required endodontic therapy, were studied. Twenty-seven subjects received standard inferior alveolar nerve block (IANB) with 2% lidocaine HCI with 1:100,000 epinephrine and 34 subjects received IANB with 3% mepivacaine with no

A fermentative enrichment culture (designated DHM-1) that grows on corn syrup was evaluated for its ability to cometabolically biodegrade high concentrations of chloroform (CF), carbon tetrachloride (CT), and trichlorofluoromethane (CFC-11). When provided with corn syrup and vitamin B12 (0.03 mol B12
