[Clinical studies on apalcillin in biliary tract infections (author's transl)]

Clinical studies on apalcillin (APPC), a new broad spectrum semisynthetic penicillin developed in Japan, were carried out, and the following results were obtained. APPC was administered to three patients with serious biliary tract infections by intramuscular or intravenous injection at daily dosage of 2. Therapeutic responses were excellent in all cases, and no side effects and abnormalities of laboratory findings were observed. APPC was considered to be an excellent drug for the treatment of biliary tract infections.

Normal chemotactic activity of granulocytes obtained by filtration leucapheresis

The chemotactic activity of granulocytes obtained by the Terumo Filtration Leucapheresis System (F.L.) was examined by the method of Boyden's chamber. The number of cells migrating through the Millipore filter was expressed as the chemotactic activity. The mean values were 117 for the F.L. and 122 in a control, in which cells were collected from the same donor blood using dextran sedimentation. The results suggested that the in vitro chemotactic function of granulocytes obtained by F.L. was within normal limits.
