134 Section PHYSIOLOGICAL ANTHROPOLOGY POPULATION STRUCTURE OF THE ISLAND OF RAB ESTIMATED BY THE ANALYSIS OF BIOCHEMICAL TRAITS Pribačić Ambrožić Vanda Institute for Anthropological Research, Zagreb, Croatia Island population isolates are best for investigating theoretical hypotheses about microevolution by applying holistic approach. <...> The aim of this research was to study the population structure of the island of Rab by the analysis of biochemical traits. <...> The sample collected in 2002 is comprised of 600 adult individuals from fi ve island settlements. <...> Biochemical traits (creatinine, urate, cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, glucose) were analyzed using multivariate biostatistical methods in order to determine the degree of heterogeneity among the populations of the island settlements and the pattern of their variation. <...> Heterogeneity among subpopulations of the island of Rab in biochemical traits was determined by blood glucose and LDL cholesterol. <...> Biochemical variability among the populations corresponds to that of previously established for morphological traits of head and body and most likely refl ects genetic differences, given the fact that those populations have been exposed to a homogenous physical environment. <...> Key words: population structure, island isolate, Rab, Croatia, biochemical traits Contact information: Pribačić Ambrožić Vanda, e-mail: vanda.pribacic.ambrozic@inantro.hr. <...> THE LINEAR GROWTH: PROGNOSIS CRITERIA IN GROWING UP CHILDREN Shcheplyagina Larisa The M.F. Vladimirskiy Moscow oblast Research Clinical Institute, Russia The linear growth is an important indicator of health and harmonious development of child. <...> It is known that dimensions of skeleton depend on content of calcium in bones. <...> Until now, it was considered that only dual-energy x-ray absorptiometry made it possible to determine amount of bone mineral in skeleton bones. <...> However, application of dual-energy x-ray absorptiometry for evaluation of growth processes in children is not recommended. <...> The implementation of qualitative ultrasound analysis of bones in pediatrics permitted to establish that this method refl ects content of calcium in cortical layer of tubular bones. <...> During last 10 years it is proved that linear growth of children of early and preschool age depend on content of calcium in cortical layer of tubular bones. <...> The original national standards of bone strength in children from birth to 16 years were <...>
