Abstract

Melatonin was measured using a specific radioimmunoassay in 1 strain of outbred mice (OF1 Swiss) and 4 strains of inbred mice, 2 of them being known to synthesize melatonin (CBA and C3H) and the 2 others being controversial (BALB/c and C57BL/6). In this study, the 5 mouse strains were able to synthesize melatonin, but the basal levels as well as the diurnal variations were very different from one strain to another. CBA and C3H strains showed a clear-cut day-night rhythm of pineal melatonin concentration, with peak levels of 276 ± 22 pg/pineal in CBA and 135 ± 12 pg/pineal in C3H. In BALB/c, the authors confirmed the presence of a very short melatonin peak (15 min) in the middle of the dark period. In C57BL/6 and OF1 Swiss, a very small but significant peak was observed in the middle of the darkness. In the former, another small peak was also observed at light onset. Whether these very small peaks, which may be related to the deficience of N-acetyl transferase activity reported by others, have a physiological meaning remains to be determined.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
