Morphometry of the pancreas in human foetuses.

چکیده
With the use of conventional anatomical dissection, radiography, digital and statistical analysis, morphometry and skeletopy of the pancreas was carried out in 60 human foetuses of both sexes (28 female, 32 male) between the 17th and 40th week of intrauterine life. The material was fixed in a 10% formalin solution. The age of the foetuses was determined by crown-rump (CR) length measurement on the basis of the Iffy et al. tables. Photographic documentation was made and then digitally processed in the Computer Image Digital Analysis System. The following parameters were taken into account: the length and width of 3 parts of the pancreas, namely the head, corpus and tail. Additionally, radiograms were made to obtain a projection of the gland on the vertebral column. Development of the pancreas was correlated with the age of the foetuses calculated on the basis of crown-rump (CR) length measurements. The correlation coefficient with CR was 0.998 for the pancreas length, 0.709 for the width of the head, 0.703 for the width of the corpus and 0.712 for the width of tail. Gender dimorphism was not found (p > 0.05) with regard to the morphometry of the pancreas. In the material under examination the pancreas did not change its position in relation to the vertebral column. The head projected on the vertebral column in the range Th(12)-L(2) (most frequently L(1)-L(2)), the corpus on Th(12)-L(2) and the tail on Th(11).

Different Thymosin Beta 4 Immunoreactivity in Foetal and Adult Gastrointestinal Tract
BACKGROUND Thymosin beta 4 (Tbeta(4)) is a member of beta-thymosins, a family of peptides that play essential roles in many cellular functions. A recent study from our group suggested a role for Tbeta(4) in the development of human salivary glands. The aim of this study was to analyze the expression of Tbeta(4) in the human gut during development, and in the adult. METHODOLOGY/PRINCIPAL FINDI...
