- Stable isotopes (delta C-13, delta N-15) have been studied in human burials from the medieval town Sigtuna in Sweden. Dietary patterns of 80 adult individuals were analyzed on three cemeteries representing the phases of establishment, prosperity and decline of the town. All analyzed individuals were radiocarbon dated. One of the cemeteries, Church 1, represents a population of higher social status than those at the other two cemeteries. The delta C-13 values are homogenous and showed that the protein intake was mainly of terrestrial origin in the whole population. delta N-15 values varies more and they may indicate a higher input of vegetables in the diet at one of the cemeteries, the Nunnan block. Already in the initial phases of Sigtuna a social hierarchy had been established which is reflected in dietary patterns. Apparently more animal protein was consumed among the high status population of the town. Furthermore, differences in dietary patterns between the sexes were noted. In all phases the females show more clustered values indicating a more homogeneous diet than that of the males.

- PURPOSE: To study the toxicology of rifabutin in the rabbit eye with emphasis on retinal function and histopathology.METHODS: Seven rabbits received a daily dose of rifabutin during 15 months. Six rabbits receiving only the vehicle were used as controls. Repeated standardized full-field electroretinograms (ERG) were assessed. After discontinuing treatment, the rabbits were killed and the cornea, the lens, and the sectioned retina was studied. Immunhistochemistry directed against vimentin, glial fibrillaryacidic protein (GFAP), protein kinase C (PKC), and peanut agglutinin (PNA) was performed.RESULTS: Rifabutin was detected in serum of the treated rabbits. During treatment, the full-field ERG demonstrated significantly reduced b-wave amplitudes in the total rod-cone response as well as in the isolated rod and cone response compared with the recordings before treatment. The control rabbits did not demonstrate a reduction of the ERG amplitudes. The treated rabbits developed a discoloration of the lens, not seen in the control group. No retinal pathology was demonstrated using immunohistochemical methods.CONCLUSION: Rifabutin causes a discoloration of the lens and reduces both rod and cone function in rabbits, but does not alter retinal morphology. Previous reports on ocular side effects caused by rifabutin are supported by the results of this study.
