[Tissue levels following intravenous administration of tetracyclines (author's transl)].

Interested by a comparative trial on tetracycline concentrations in gallbladder, bile and peritoneum 3 hours after administration, we wanted to know the long-term tissue concentrations, measured towards the end of a 24-hour off-drug interval, as these concentrations are particularly important for a bacteriostatic drug. We found that the tissue concentrations of doxycycline in gallbladder wall, lung, muscle, and thyroid gland were 2 to 3 times higher than those of pyrrolidino-methyltetracycline. The concentrations in the skin, in various sections of the intestinal tract and of the peritoneum, and in the gallbladder content were about the same for both drugs. The implications of these data for therapy are discussed.

[Follow up study of patients operated on metastases of the lung and pleura (author's transl)].

From 1956 til 1974, 1851 patients have been operated on a malignancy of the lung. 29 of them had a solitary lung metastasis and 2 of them a metastasis of the pleura. Among those, the primary malignancies showed the following frequency: 7 malignancies of the uterus, 7 sarcomas, 4 carcinomas of the breast, 4 carcinomas of the large bowel, 4 malignant goiters, 3 hypernephromas, 1 seminoma and 1 malignancy of the pancreas. The mean survival time was 3.3 years. 25.8% of the patients survived 5 years. Patients with a primary malignancy of the uterus appear to do best. In case of repeated metastases we did not operate upon again.
