Basal dendrites of hippocampal CA1 pyramidal cells in senile dementia of Alzheimer type (SDAT) were studied quantitatively by the Golgi impregnation method. The present data suggested that basal dendrites of the pyramidal cells were decreased in number in SDAT, and that the dendritic decrease was associated with a decrease in size of their cell bodies.

in this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. the copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. reaction temperature and concentration ratio of the reducing agent to the precursor (r/p) as two main conditions i...

Treponemal infections in wild European brown hares (Lepus europaeus) from The Netherlands were diagnosed by means of serological tests for human syphilis and histological demonstration of spirochetes by the Bosma-Steiner silver impregnation method in histological sections of skin lesions. The treponeme should probably be classified as "Treponema paraluisleporis."

The development of the motor nerve ending has been studied by many investigators (TELLO, 1922, VISINTINI e LEVI-MONTALCINI, 1939; CUAJUNCO, 1942; KUPFER and KOELLE, 1951) and authors such as GEREBTZOFF (1959), MUMENTHALER and ENGEL (1961), and WAKE (1964) used the chick skeletal muscle to examine the morphogenesis of the ending. However, their studies were confined to the light microscopic obse...

There exist several options for local antibiotic therapy in orthopaedic and trauma surgery. Over the past years, the use of antibiotic-impregnated bone grafts (AIBGs) has become a popular procedure in the treatment of bone and joint infections. A major advantage of AIBGs involves the possibility of impregnation of various antibiotics depending on the sensitivity profile of the causative organis...

The importance of neurofibrillar impregnations in the study of the nervous system needs no emphasis. However, the silver methods currently used involve such a complex of variables that the results are by no means constant. The present communication is devoted to the problem of interpretation of results, together with certain fundamental relations between brain tissue and silver solution. The mo...

Previously we observed that corticosteroids alter Calbindin-D28k immunoreactivity in the rat hippocampus. In the present study we investigated whether prolonged subordination stress, presumably producing elevated plasma corticosterone levels (1) altered the immunocytochemical distribution of the Ca(2+)-binding proteins Calbindin-D28k (CBir) and Parvalbumin (PVir) in the rat hippocampus, and (2)...

A summary of usage of ultrasound in traditional textile technologies and a present literature review about new possibilities of usage of ultrasound in textile branch are the first part of this contribution. Second part is focused on a possibility of computer simulation of high frequency wave propagation by means of cellular automata method. An own program for longitudinal harmonic wave simulati...
