- A study of the general and dental health and the food habits of randomly selected 4-year-old Swedish urban children was performed. The results were compared with the findings of an investigation carried out four years earlier in the same area. In comparison with the earlier study no significant differences were found in haemoglobin values, packed red cell volume, microsedimentation rate and anthropometric measurements. The food habits had altered. A reduction in the frequency of between-meal consumption, particularly of sweets and soft drinks, as well as a reduction of the frequency of meat, fish and egg consumption was found. The children had an increased sandwich and milk consumption. The caries frequency was markedly reduced, which might be explained by the decreased between-meal consumption and an increased consumption of fluoride tablets. The food habits and the caries situation were generally influenced by the parents' socio-economic conditions, especially their educational level.

- A polar fucose-containing glycosphingolipid fraction isolated from dog small intestine has been characterized by mass spectrometry of intact methylated, and methylated and reduced (LiAlH4) glycolipid. The native fraction, which was homogenous on thin-layer chromatography, was shown after methylation to be a mixture of two compounds. One was identified as a hexaglycoslyceramide with the following composition and sequence: fucose-hexose(fucose)-hexosamine-hexose-hexose-ceramide, with a terminal saccharide structure similar to blood group Leb determinants. The second compound was a novel heptaglycosyceramide with the sequence: hexosamine(fucose)-hexose-tfucose)-hexosamine-hexose-hexose-ceramide. This glycolipid was also detected in human small intestine and pancreas. The dog intestinal fraction had phytosphingosine as its major base and contained almost exclusively 2-hydroxy fatty acids (16 : 0--24 : 0). The fraction of human pancreas differed in having spingosine as its major base and normal fatty acids (16 : 0--24 :0) as major acids.
