Objective: In the present study, we aimed to investigate morphological and biochemical effects of alpha-lipoic acid (ALA) on bladder injury caused by water avoidance stress (WAS) show its effect number degranulated mast cells, which increase after stress. Materials Methods: Wistar albino rats were subjected WAS animals in treatment group injected ALA. After urinary tissues routine tissue proces...

A 33-year-old HIV negative Brazilian engineer who had been living in Australia for three years presented to his dentist with an eight week history of a progressively enlarging maxillary gingival ulcer, suspicious malignancy. Biopsy the lesion showed pseudoepitheliomatous hyperplasia round structures present periodic acid-schiff and grocott stains suggestive fungal organism. second biopsy reveal...

Clear-cell variant of oral squamous cell carcinoma is an extremely rare entity. change can be seen in any the neoplasms, but as pure form variant, it difficult to find head-and-neck SCC. We hereby present a case report 71-year-old male who presented with growth erythematous patches on lateral pharyngeal wall for past 3 months. Histopathologic examination showed nests, islands and sheets maligna...

The eosinophils of a patient with eosinophilic leukaemia were studied with 13 different cytochemical methods using light and electron microscopy. Apart from the 'left shift' of the eosinophils in bone marrow and peripheral blood, the following morphological changes were noted: uncoordinated maturation of the nucleus and cytoplasm, changes in size of the specific granules, and hypogranulation to...

I . The scale of the roach (Leuciscus rutilus L.) was examined for state of calcification, metachromasy, and reaction to the periodic acid / Schiff (PAS) test. 2. Metachromasy and a positive PAS-reaction imply acid mucopolysaccharides in the bony layer. 3. There is a great increase in these reactions and in reactions for bone salts in the transition zone between the uncalcified and calcified pa...

Parathyroid glands from laying hens were also  xed in percent glutaraldehyde in phosphate buffer (0.1 M, 7.3 pH) for araldite embedding and used for electron microscopy. For routine histological observations, sections of 5 to 6 um thickness were cut and stained by, Mayer’s haemalum and eosin-phloxine, Masson’s trichrome, Crossman’s modi cation of Mallory’s triple stain, van Gieson’s method fo...

Abstract The majority of Alzheimer’s disease (AD) cases are late-onset and occur sporadically, however most mouse models the harbor pathogenic mutations, rendering them better representations familial autosomal-dominant forms disease. Here, we generated knock-in mice that express wildtype human A? under control App locus. Remarkably, changing 3 amino acids in sequence to its wild-type counterpa...

A six-year-old male castrated domestic shorthair cat was evaluated for a six-month history of haematochezia, mucoid diarrhoea, tenesmus and rectal prolapse. Colonic histopathology revealed multifocal mucosal ulceration lamina propria infiltration with large numbers periodic acid-Schiff-positive macrophages. Large clusters intracellular Escherichia coli were confirmed fluorescence in situ hybrid...

this study was conducted to evaluate histochemical alterations of river buffalo’s uterine wall acid andalkaline phosphatases (alp and acp), lipase and carbohydrate ratio during follicular and luteal phases.forty apparently healthy and non pregnant river buffalos were considered for removal of the uterus aftersacrifice in slaughterhouse. all dissected uteri were divided into two luteal (by obser...

Two methods used for the electron microscopic detection of glycoproteins were applied to a variety of cell types in the rat; one involved successive treatment of sections with periodic acid, chromic acid, and silver methenamine; and the other, a brief treatment with a chromic acid-phosphotungstic acid mixture. The results obtained with the two methods were identical and, whenever the comparison...
