Optimum and tolerated intake of fluorine.

Optimum and tolerated intake of fluorine has been studied on the basis of body weight, caloric and fluid requirement of subjects belonging to different age groups. The main F-source is consuming drinking water, and this normally contains 1 mg F/l. Thus, that amount of F should be considered optimal which is ingested with drinking water containing 1 mg F/l. The optimum per kg of body weight is 0.045 mg in infants. It decreases with age, in adults it amounts to half the optimum for infants on a mg/l basis. The tolerated and the chronic tolerated toxic amounts have been estimated for the different age groups.

Urinary fluoride levels after consumption of fluoride-poor drinking waters in Hungary.

Fluoride concentration in the urine of subjects drinking fluoride-poor water was investigated. In the first series of experiments, mean F concentration in the urine collected for 24 hours was 0.26 mg/litre, in the second series, 0.28 mg/litre, and in group fractions 0.20 mg/litre. Standard deviations ranged from 0.07 to 0.12 mg/litre. No conclusion could be drawn from the F level of a single urine fraction to the 24-hour F level of the same subject. In group tests, means reflected the expected 24-hour values. There were differences in the urinary F levels of the subjects. Values for the same subject also varied; they were different on different days and the fractions collected on the same day showed variations. Older people excreted more fluoride than young ones. These findings are in good agreement with published data.

[Globular corpuscles in hepatomas of Swiss mice].

In hapatomas formed spontaneously without cirrhosis at Swiss mice numerous globular corpuscules of eosinophil character were found. These corpuscules as revealed by electron microscopy are formed in cyternas of the rough surfaced endoplasmatic reticulum and are of the nature of protein.
