Background: Recent reports demonstrated that intravenous route as a minimally invasive method, similar to direct injection, is suitable for bone marrow stromal cell (BMSC) transplantation. In this study, we made a comparison of intraspinal and intravenous route of BMSC administration to repair injured spinal cord tissue. Methods: Six groups of adult female rats were used in this study. Laminect...

Infiltration of the lamina propria of the mucosa of the small intestine with 'foamy' macrophages (histiocytes) which give a strongly positive cytoplasmic reaction with the periodic acid-Schiff (P.A.S.) stain is considered diagnostic of Whipple's disease (Black-Schaffer, 1949; Chears, Hargrove, Verner, Smith, and Ruffin, 1961; Farnan, 1958; Plummer, Russi, Harris, and Caravati, 1950; Sieracki an...

This study puts forth the morphological and metabolic modifications that occurred in the skin affected by Pemphigus vulgaris, modifications that have been studied by histoenzymatic techniques. There were studied skin biopsies from patients suffering from Pemphigus vulgaris, hospitalized in Dermatology services in Bucharest. The pieces were sectioned at cryotome, at 3 degrees C and then they wer...

Intriguing questions have recently been raised regarding the applicability of direct observations of the pial microcirculation to the behavior of the total cerebral microcirculation. Operating under the assumption that arteriolar tone and, thus, cerebrovascular resistance is, to some extent, directly related to the intrinsic energy metabolism of the arteriolar wall, a comparative histochemical ...

PURPOSE The purpose of our study was to investigate the histological, histochemical and ultrastructural aspects of the proximal femoral growth plate in slipped capital femoral epiphysis (SCFE). METHODS Eight core biopsies of the proximal femoral growth plate were performed during in situ epiphysiodesis in patients with SCFE that was at the pre-slipping stage in two cases and at the mild slipp...

background/objective: despite the present routine treatment of septic arthritis with antibacterial agents, articular damage is persistent and frequently leads to loss of joint function.  the aim of this study was to assess the effect of intra-articular corticosteroids added to systemic antibiotics in the treatment of experimental staphylococcal knee joint infection in rabbits.   methods : thirt...

The changes of the adrenal cortex caused by corticosteroids and ACTH, were studied histochemically using T.T.C. (2-3-5 triphenyl tetrazolium chloride), one of the tetrazolium compounds. T.T.C. is a water soluble and colorless crystalline substance, changes unsoluble in water, soluble in oil, and forms a pink colored precipitation (formazan) by a reducing process. Zweifach et al. (1951) incubate...

The aim of the present paper is to describe the morphology and topography of the nuclei of the amygdaloid complex in the rabbit. In the current study we also investigated the intensity of the enzymatic reaction for acetylcholinesterase (AChE) in the amygdaloid complex and the morphology of its neurones. Material consisted of 5 brains of adult New Zealand rabbit, stained either with cresyl viole...

A histochemical study was made of 13 cases of lipidoses of the central nervous system. Niemann-Pick's disease can be differentiated from other cerebral lipidoses by the finding that all affected cells store histochemically stainable phospholipids. Evidence has been adduced indicating that the material stored in infantile amaurotic idiocy is a complex containing ganglioside, cholesterol, and pos...

The duodenum is largely responsible for the breakdown of food in the small intestine, using enzymes. Duodenal submucosal glands, which in general produce a mucous secretion, exist in all mammalian species. These glands are located in the submucosa of the proximal duodenum. The study aimed to demonstrate the morphological and histochemical properties of duodenum and duodenal submucosal glands in...
