The ossification of tarsal bones and distal end of the tibia in human foetus.

The ossification level of tarsal bones and the distal end of the tibia in human foetuses of both sexes from 4 to 9 month gestational age was estimated. Our results show that ossification of the cartilaginous model tarsal bones begins from 6 to 7 months of the gestational age with the appearance of a single ossification point in the ankle bone and two ossification points in the heel bone with the following ossification of the periosteum.

Rare case of the accessory radial artery.

The accessory radial artery passed laterally to the brachial artery and then radial artery, and finally it anastomosed with the princeps pollicis artery.

Prenatal development of the human humerus.

Fetuses from 105-250 mm C.-R. length were investigated. Using special software dimensions were taken from X-ray pictures. Quantitative changes occurring in humerus during fetal period were determined and expressed graphically.

[Anatomic and radiologic studies of of ovarian arteries in women of various ages].

The main source of ovarian arterial blood supply is so called an ovarian arcade. It is an arterial system made of the uterine and ovarian artery junction. Depend on the source of information, there are different descriptions of ovarian arcade vessels, as well as there are different anatomical nomenclature. Anatomical material was taken from 63 women aged 15 to 85. Arterial vessels were appropriately prepared, filled with contrast medium and X-ray examined. An ovarian and uterine vessels junction into the ovarian arcade was observed in the all examined material. In order to be include into the arcade, an appropriate vessel diameter had to be stated at the level of uterine and tubal end. In multiparas in comparison with nulliparas, an average diameter was bigger about 17%. Number of vessels, the arcade gives to ovarian hilus is also of variable quantity. There are markedly less vessels in postmenopausal women.

Cortical branches of the middle cerebral artery in human fetuses.

In 30 human fetuses, aged 20-31 weeks, the middle cerebral artery and its cortical branches were investigated with injection method. The cortical branches pass on the superlateral surface of the cortex and from a dense net communicating with corresponding vessels of the anterior and posterior cerebral arteries.

[Vascularization of the lumbar spine in the human fetus].

The vascularization of the lumbar spine has been studied in 19 human fetuses of both sexes after filling of the arterial system with Micropaque. Structural radiographs were taken and lumbar arteries with their branches were marked in every segment examined. The frequency of branches incidence was described. The differences in vascularization between left and right side of the lumbar spine within medullar arteries and articular processes arteries amounted to 20 and 5 per cent respectively.

Rare cases of arteries branching directly from aortic arch in the man.

In the autopsy material of 118 human cadavers (67 males and 51 females), conserved in 10% formaldehyde, two cases were found in which abnormal arteries originated directly from the aortic arch. In the first case the right subclavian artery branched off the aortic arch below the left subclavian artery. In the second case, the sequence in which large arteries branched off was as follows: brachiocephalic trunk, left common carotid artery, left vertebral artery, left subclavian artery. The vascular anomalies were confronted with clinical symptoms documented in case history and in laboratory results.

[Vascularization of the posterior wall of the urinary bladder in women after past cesarean section in light of microangiographic studies].

Arterial vascularization of membranes in the urinary bladder wall has been studied in 14 women of reproductive age, who were bearing children. Four of them had exclusively spontaneous deliveries. Ten delivered at least once by cesarean section. The studies consisted in filling the uterine, ovarian and vesical arteries with Microtrast preparation. After the filling of vessels and fixation of the preparation in 10% formalin solution, specimens, 4-5 mm thick, were taken from the bladder wall at the junction with uterus, and comparatively specimens from the free parts of the uterus body. The serial specimens were used to obtain photographs by means of X-ray apparatus with microfocal tube, being implemented for structural studies. On the basis of the above-mentioned investigations we disclosed that the course of the blood vessels in membranes of the urinary bladder wall undergoes changes after routine dissection during the cesarean section. There is a disappearance of regular arrangement of the vascular network, particularly in mucous membrane. New vessels of larger calibre with an irregular course are seen to appear throughout the entire width. Such changes were not detected at sites distal to the field of operation. Specimens stemming from the urinary bladders of women, who delivered spontaneously, failed to reveal such changes.

Vascular changes and inflammatory infiltrations in primary lung cancers.

Twenty one surgical specimens of lung cancer were studied. Microangiography showed that the vascularization of the tumours did not depend either on the size or histology of carcinoma. Abundant vascularity of tumours was associated with the degree development of connective tissue--vascular stroma. Poor vascularity was linked with neoplastic blockade of vessels and the presence of necrosis. Besides the cancer tumour the vascular changes existed in all parts of the lung, but they were expressed most profusely in the surroundings of neoplastic infiltrate. The range of histological vascular changes was as follows: elastosis, inflammation, lumen obliteration (proliferation of intima), wall thickening (arterialization of veins), oedema, hyalinization, plasmorrhagia, fibrosis (scarring), presence of acid GAG, thrombosis. The most striking vascular changes were connected with hilar and intralobar localization of the tumour, the mildest with subpleural position. The intensity of vascular changes depended on the size of tumour and existence of necrosis. The extent of necrosis and the histological type of neoplasm exerted no essential effects in this respect. Inflammatory cell infiltration appeared abundantly in the direct vicinity of the tumour in adenocarcinoma, with hilar localization and displayed proportional dependence on the size of tumour and the extent of necrosis, but the tumours, whose diameter exceeded 6 cm, failed to have any effect on the intensity of the inflammatory cell reactions.

[Vascularization of skin-muscle flap from greater pectoral muscle].

The results of studies on vascularization of skin-muscle flap from greater pectoral muscle have been presented. Flaps taken from human dead bodies were injected by Micropaguae preparation and then the range of vascularization of greater pectoral muscle by thoracoacromial artery and its branches was estimated on roentgenograms. It has been found that t.p.b. pectoral branch is characterized by small variation of the run that enables safety utilization of the flap in clinical practice.
