Complexes of Ferrous Iron With Tannic Acid

Solutions of tannic (digallic) acid at concentrations of 5 or 50 parts per million reduce dissolved ferric iron to the ferrous state when the pH is less than 4. In solutions with a pH of 4 or more, a black material containing ferric iron and tannic acid is precipitated. In a solution containing 500 parts per million of tannic acid, a ferrous complex forms at a pH of more than 5. This complex is...

The hepatocarcinogenicity of tannic acid.

In the group of chemical hepatocarcinogenic agents, the number of which has steadily increased in recent years (:$7), tannic acid deserves attention. Owing to its astringent effect, this compound was formerly used widely in therapy. The local treatment of thermal burns with tannic acid was suggested by Davidson (1935), and his procedure was generally employed in Hungary during World War II. I t...

Tannic Acid in the Treatment of Burns

To ilic Editor, The Indian Medical Gazette. Sir,?During the past few years, tannic acid has come into considerable vogue for the treatment of burns. As House Surgeon in the Sir J. J. Hospital in Bombay in 1927-28 I had to treat many cases of burns, but was unsuccessful with tannic acid. I asked my chief, Mr. S. R. Moolgavkar, f.r.c.s., as to the reason for this, and he gave me the following adv...

Tannic acid-stained microtubules with 12, 13, and 15 protofilaments

Subunit structure in the walls of sectioned microtubules was first noted by Ledbetter and Porter (6), who clearly showed that certain microtubules of plant meristematic cells have 13 wall protofilaments when seen in cross section. Earlier, protofilaments of microtubular elements had been described in negatively stained material, although exact counts of their number were difficult to obtain. In...
