Histological studies were performed on 30 pancreases obtained from normal human fetuses aged between the 9th and 38th week. For immunocytochemistry, the avidin-biotin-peroxidase method was used to identify and colocalise insulin, glucagon, somatostatin, pancreatic polypeptide and proliferating cell nuclear antigen. In the 9th week, cells containing all… (More)
The development of the human fetal adrenals starts in the 6th week gestational age and adrenal C19 steroid production becomes of major importance for the maintenance of the pregnancy. Therefore, in the present study, human fetal adrenals at 6 weeks of gestational age were immunostained for 17 alpha-hydroxylase, the key enzyme for the production of… (More)
Histological and morphometric studies were performed on 30 thyroid glands obtained from normal human fetuses. Their crown-rump length (CRL) ranged from 57 to 190 mm, corresponding to the gestational age of 10-20 weeks. The weight of the thyroid gland increased proportionally in relation to CRL, foot length and fetus weight. The first follicles containing… (More)
OBJECTIVE Endovascular procedures are gaining more and more popularity as treatment of great saphenous vein (GSV) incompetence. The purpose of the present study was to assess the efficacy of steam GSV ablation. METHODS Steam ablation using the steam vein sclerosis system (CERMA, France) was performed in 20 patients with GSV incompetence. The efficacy of… (More)
Investigations were performed on 12 embryos and 76 fetuses aged 6 to 40 weeks. The uterine cavity is formed in 12th week. During fetal period the uterus grows most intensively between 16th and 24th week. Up to 16th week the fundus of the uterus is at the level of 1st sacral vertebra. From this period the fundus is located at the level of 2nd sacral vertebra.
The neural stem cells are primary precursors that can self-renew and generate differentiated neurons and glia. Such cells were cultured from adult nervous system. They were identified in the subventricular zone, hippocampus, spinal cord, ependyma and even were cultured from astrocytes. These cells are key players in the formation of the nervous system… (More)
The genuine destruction of a synthetic prosthesis wall, as a late complication of vascular surgery, is extremely rare. We report a case of a 64-year-old male who had his 12-year-old femoropopliteal synthetic graft explanted due to two large pseudoaneurysms in the middle section of the graft. Microscopic evaluation demonstrated the areas of focal thinning… (More)
Investigations were made on serial sections of human embryos at developmental stages 16 and 17 (37-41 days). The spinal nucleus of the accessory nerve presents well delimited cellular group in the dorsplateral part of the ventral horn of the spinal cord. The migration zone is still present. In embryos of stage 16 the spinal accessory nerve joints the fibers… (More)
Recent studies have showed that the ependymal cells and subventricular zone astrocytes are neurosphere-initiating cells and are neural stem cells. They give rise to neurons and glial cells in response to injury and utilization of endogenous stem cells in the treatment of nervous system diseases is important strategy in neurogenesis.
