[Clinical experience of therapeutic use of cefmetazole (cefmetazon) or bronchopneumonia (author's transl)].

1. Therapeutic effects of cefmetazole (cefmetazon, CMZ) were examined in 22 cases of bronchopneumonia. 2. Among the 22 cases, 17 cases (77%) showed better response than 'effective'. However, 10 cases (91%) showed better response than 'effective' if a daily of 4 g (11 cases) was taken into consideration. 3. No particular symptomatic side effect of CMZ was shown. Abnormality in such laboratory tests as transaminase (1 case of GOT, and 2 cases of GPT) and 1 case of alkaline phosphatase were observed, and the abnormality was ascribable to CMZ administration.

Guinea pig lung lavage cells after intranasal BCG sensitization.

Recent studies have suggested that intranasal administration of antigen can induce local cell-mediated immunity in lung lavage cells. The present study was designed to examine the changes in composition of lung lavage cells and their capacity to produce the lymphokine migration inhibitory factor after intranasal immunization with BCG in guinea pigs. Results indicate that guinea pigs responded to respiratory tract BCG infection with an increase in immunocompetent cells in the bronchoalveolar tract and with production of migration inhibitory factor. After local pulmonary BCG administration, the total number of cells increased as compared with that of the uninfected animals, the increase being statistically significant within 2 weeks. This marked increase in the total cell population is due to a more than doubling of the number of macrophages in the lavage fluid. Animals also developed at this time positive delayed hypersensitivity to intradermally administered purified protein derivative. A significant increase in the total lymphoid cells and macrophage population was observed again at 6 weeks after sensitization, suggesting that the response is biphasic in nature. At 6 weeks, however, there was also a significant rise in total lymphocytes and T cell population in addition to macrophage numbers. This increase in T cells correlated with an increase in production of migration inhibitory factor in the presence of purified protein derivative. These data suggest that the immune response of the respiratory tract after BCG challenge involves increased recruitment of immunocompetent cells locally at the site of infection and that these cells are capable of producing effector molecules in terms of the elaboration of migration inhibitory factor.
