Intravenous administration of tetracycline has been known to result in fatty degeneration of the liver. This study was undertaken in order to elucidate some of the actions of tetracycline on mammalian cells in culture and to attempt to relate these findings to the clinical condition of fatty degeneration of the liver mentioned above.It is suggested that lipid accumulation occurring after tetracycline administration is possible the result of a decrease in B-lipoprotein synthesis and enzyme inhibition. These factors could result from the high blood levels of tetracycline seen after large and rapid intravenous injections of the drugs into normal patients or those suffering from kidney impairment.

The antibiotics have become so widely and successfully used in the practice of medicine that they are now considered to be essential. Among the antibiotics, the tetracycline group has achieved an enviable reputation for dependable medication, In spite of this, there remain several unanswered questions, One of these pertains to the interesting phenomenon for almost selective localization of tetracycline in certain tumor cells or masses, Although there have been numerous publications dealing with this phenomenon, as the following paragraphs will indicate, there is little agreement as to the factors involved. Indeed, there are some sharply conflicting opinions. The investigations described in this paper were undertaken to obtain information relative to the localization and retention of tetracycline in a transplantable mouse tumor.
