Dimension of circumflex branch according to type of heart vascularisation in foetal life of human

Typological differentiation of coronary arteries binds to various areas of vascularisation, which could suggest essential differences between vasculatory dimensions. There are not many papers analysing the influence of heart vascularisation on epicardial vessel dimensions during postnatal human life, furthermore, there are hardly any papers dealing with the prenatal period. The subject of examination was 188 human foetuses from 4th to 7th month of prenatal life. Foetuses were fixed for minimum 3 months in 9% formalin solution. They were taken from natural abortions and did not characterise any external malformations. There was a different number of foetuses in a variety of morphological age groups. Adachi classification was used to describe all types: type I - classical, with equal coronary arteries, type II - predominance of right coronary artery, type III - predominance of left coronary artery. Speed of circumflex branch growth in different types of vascularisation is various. Analysis of the differences among dimensions of artery in various types showed there are statistically crucial ones, especially between: types III and I or types III and II

Correlation of heart external dimensions with body external dimensions of human foetuses

In an evaluation of foetal hearts in II and III pregnancy semester, correlation with exterior foetal dimensions should be taken into consideration. It is interesting also if all exterior heart dimensions are correlated at the same level with overall body dimensions. The subject of examination was 204 foetuses of both sexes, including 106 males and 98 females, in 5th and 6th month of foetal life. Foetuses were fixed for minimum 3 months in 9% formalin solution. They were taken from natural abortions, without exterior features of developmental malformations. Examined material was evaluated in month groups of morphological age. The number of foetuses in different groups was various. Exterior heart dimensions were considered: height, width, heart depth, and also heart circumference in coronary sulcus (atrial-ventricular). Exterior dimensions of foetuses were: vertex-plantare, vertex-tubulare. All exterior dimensions of heart are closely and strongly correlated with both exterior dimensions of foetuses

THE SPECIFICITY OF HUMAN FOETUSES IN THE LIGHT OF DATA CONCERNING THEIR MOTHERS

THE SPECIFICITY OF HUMAN FOETUSES IN THE LIGHT OF DATA CONCERNING THEIR MOTHERS was investigated basing on clinical anamneses from the mothers of 500 foetuses and 6000 viable newborns.' The analysis included the age of the mothers, their profession, age at menarche, length and regularity of. the menstruation cycles and birth intervals

Variability of weight in the prenatal and perinatal stages of development

Variability of weight in the prenatal and perinatal stages of development was examined on a sample of 5904 newborns and 354 fetuses in the age of 4 -7 months. All the sexual differences as well as some mothers’ traits and the circumstances of childbirth were taken into consideration

BIOMETRICAL STUDIES OF HEART AND GREAT ARTERIAL VESSELS IN FETAL ONTOGENESIS

BIOMETRICAL STUDIES OF HEART AND GREAT ARTERIAL VESSELS IN FETAL ONTOGENESIS. The paper contains the results of the investigation of selected dimensions of heart and great vessels. The'studies were carried out on a total of 197 fetuses (98 males and 99 females) in the age from the 3rd to 7th month of perinatal life. The aim of this work was to receive the data on the process of formation of sexual differences in the dimensions of: heart, aorta, pulmonary trunk, aortic arch ramifications, and the course of their growth rate

Variability of weight in the prenatal and perinatal stages of development

Variability of weight in the prenatal and perinatal stages of development was examined on a sample of 5904 newborns and 354 fetuses in the age of 4 -7 months. All the sexual differences as well as some mothers’ traits and the circumstances of childbirth were taken into consideration

THE SEXUAL DIMORPHISM IN PRE- AND POSTNATAL DEVELOPMENT OF THE HUMAN LARYNX

THE SEXUAL DIMORPHISM IN PRE- AND POSTNATAL DEVELOPMENT OF THE HUMAN LARYNX. Fourteen diameters, generally characterizing the larynxes of Poles from the 4th fetal month to the 90th year of life were analysed. The authors' material consisted of 200 normal fetuses. Postnatal material (956 specimes) was reinterpreted after recounting data from literature
