rodlet cells are frequently found in teleost fishes and although their role in organisms is not completely understood. the occurrence of these cells are related to stress and may undergo changes in contaminated environments, thereby allowing their use as biomarkers. this hypothesis is tested in the present study. thirty specimens of oreochromis niloticus were divided into three groups, two grou...

introduction: serum c-reactive protein (crp) is believed to be increased in metastatic urothelial cancer of the bladder. however, the changes depend on the stage and grade of the upper tract urothelial carcinoma (utuc). this study aimed to compare low-range and high-range serum crp and haptoglobin in new cases of utuc. materials and methods: blood was collected from newly diagnosed patients wit...

Mildly disrupted cells of Chlamydomonas reinhardi Dangeard were incubated in a reaction medium containing glycolate, ferricyanide, and cupric ions, and then processed for electron microscopy. As a result of the cytochemical treatment, an electron opaque product was deposited specifically in the outer compartment of mitochondria; other cellular components, including microbodies, did not accumula...

1. The cytological and cytochemical properties of the Ehrlich tetraploid and hyperdiploid, TA3 tetraploid and diploid, Krebs 2B, sarcoma 37, MC1M, 6C3HED and DBA lymphoma, and lymphoma #1 ascites tumors at a fixed interval after transplantation are described. 2. No qualitative differences were observed in the cytochemical properties of the nucleus, nucleolus, parachromatin, parachromatin bodies...

Acid phosphatase (AP) reaction is a specific cytochemical marker for T-cell lymphoblastic leukaemia (T-ALL). Twenty six cases of ALL were diagnosed as T-ALL employing cytochemical profiles including AP and sheep red blood cell rosettes. Three district patterns of AP reaction were observed. On one end of the spectrum, 100% of the positive blasts showed the classical dot-like reaction while on th...

We have previously shown that human polymorphonuclear leukocytes (PMNs) killed organisms belonging to both human biovars of Chlamydia trachomatis. However, the mechanism of destruction was still unclear. We therefore conducted an ultrastructural and cytochemical study to investigate the mechanism of chlamydial degradation. PMNs were inoculated with the trachoma serovar B (B/TW-5/OT) or with the...

Acute community-acquired bacterial meningitis (BM) requires rapid diagnosis so that suitable treatment can be instituted within 60 minutes of admitting the patient. The cornerstone of diagnostic examination is lumbar puncture, which enables microbiological analysis and determination of the cerebrospinal fluid (CSF) cytochemical characteristics. However, microbiological testing is not sufficient...

Acid phosphatase levels in pure lymphocytes from normal individuals were determined cytochemically on intact cells and spectrophotometrically on cell extracts. Good correlation was demonstrated between the results obtained with both methods. Biochemical assay showed that a normal range of 7.2 +/- 0.9 and 7.1 +/- 1.0 mMoles per 10(6) lymphocytes was obtained without and with tartrate inhibition,...

Tartrate-resistant acid phosphatase (TRAcP) has been an indispensible marker for hairy cell eukemia (HCL) for over two decades. However, the traditional TRAcP cytochemical stain cannot be performed effectively on sections of paraffin-embedded tissues that are important resources for histopathologic evaluation in diagnosis and treatment of HCL. Wide variation in expression of TRAcP activity by h...

Ultrastructural and cytochemical features of phagosome degradation were examined in the tapetal retinal pigment epithelium (RPE) of the opossum. Didelphis virginiana. The tapetal RPE cells of the opossum measure as much as 100 micrometers in thickness, and the phagosomes traverse these cells so as to occupy a narrow region along the basal border. Both ultrastructural and cytochemical observatio...
