The protein binding in the kidney was studied in vivo by cationic ferritin microinfusion into rabbit proximal tubules. After ferritin infusion, the protein was located in the small endocytic vesicles, large endocytic vacuoles, dense apical tubules and lysosomes, initially it was in the apical part of the cells, then progressively with time it was transported to the basal part of the cells. In addition, feritin was seen in small tubulo-vesicular structures in the apical cytoplasm. These structures with a diameter of 0.03-0.05a’m were oftcn found around ferritin-loaded vacuoles and occasionally it connected to these vacuoles. Furthermore, small clusters of ferritin particles were found in the basolatcral intercellular spaces, after tubular microinfusion of ferritin 15 min later only small amounts were observed but the number of cluster increased with time after ferritin infusion. The study demonstrates the transcytosis of protein in rabbit proximal tubules, and describes a novel ferritin containing tubulo-vesicular structures.

The association between relative skeletal age and fat patterning was analyzed by using data from the Fels Longitudinal Study for boys at chronological ages 8 to 17 years. Fat patterning, as indicated by age-specific means for three skinfold thickness indices adjusted for weight/stature2, was peripheral between 8 to 12 years of chronological age but began to increase in a centripetal direction towards a generalized distribution after 13 years. From 14 to 17 years of chronological age, boys with advanced relative skeletal ages had more centripetal fat patterns, as indicated by the ratio subscapular/(subscapular+triceps) skinfolds, than did those with retarded skeletal ages. The mean annual increment in this ratio was significantly greaterfrom 13 to 14 years of chronological age in boys with advanced relative skeletal ages than in those with retarded relative skeletal ages. Fat pattern index scores at 17 years of chronological age, however, could not be predicted from relative skeletal ages at 7, 11, or 14 years after adjustment for baseline fat pattern index scores and weight/stature2. It was concluded that fat patterning, as quantified by the ratio indices used in this study, was associated only weakly with relative skeletal age in boys. Fat patterning may be associated more strongly with other indicators of relative maturity such as secondary sex characteristics in adolescent boys.
