با توجه به اینکه کونژکتیویت باکتریال یکی از بیماریهای چشمی است و یک مشکل بهداشتی محسوب می شود که می تواند یک معضل اجتماعی نیز باشد و شدت و علل متفاوتی داشته و درتشخیص افتراقی سایر علل red eye مطرح است ، از اینرو شناخت این بیماری و بررسی علل ایتولوژیک آن از نظر انتخاب درمان مناسب و پیشگیری از عوارضی که بعدا بیمار را تهدید می کند ضروریست از اینرو تعیین شاخصهای ایتولوژیک و دموگرافیک را طلب می ...
this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...
Melanoacanthoma is a rare benign mixed tumor of both keratinocytes and melanocytes. Although some authors said that it is a rare variant of seborrheic keratosis, it has clinical and histological features distinct from seborrheic keratosis. It has large dendritic melanin-laden melanocytes throughout all levels of epidermis showing a disruption of melanin transfer from the melanocytes to neighbor...
Fractions of rat liver microsomal phospholipid that inhibit gulonolactone oxidase are described. The inhibition was shown to be complete and occurs rapidly after the reaction has proceeded at the control rate for 20 to 30 min. It could be totally reversed by the addition of tocopherol, Mn++, Co++, or ethylenediaminetetraacetate. The inhibitory activity of the phospholipid was lost by enzymic cl...
The cytological dilemma of distinguishing malignant cells from proliferating mesothelium has generated volumes of research but no clear consensus regarding an optimal staining panel. nm23 has been frequently described in malignant cells as a metastasis suppressor, but its mechanism of action and the relationship between nm23 expression, metastases, and prognosis is controversial. This is the fi...
Immunohistochemical stains are indispensable for problem solving in diagnostic pathology. In order to evaluate them appropriately, it is critical to be aware of the characteristics of a true positive stain and a false positive stain. A "true positive" stain shows chromogen deposition in cells or structures that truly contain the antigen of interest. In contrast, a "false positive" stain is one ...
A simple spectrophotometric assay for serum guanase based on the oxidation of 2,2'-azino-di(3-ethylbenzthiazoline-6-sulphate) (ABTS) using xanthine oxidase, uricase and peroxidase is described and statistically examined through its application to normal and pathological sera. The method is very sensitive, precise (CV below 8.13%) and linear up to 152.5 U/l. Comparison with the methods of Hue & ...
Localization of specific mRNA molecules within large and diverse sample sets is often hampered by the limitations of traditional in situ hybridization (ISH) methods. RNAscope ISH is an improved method for localizing mRNA molecules more specifically, more rapidly, and with greater sensitivity than previously possible with conventional ISH methods. RNAscope ISH utilizes pairs of ‘Z-probes’ that a...
در کار حاضر، سه رنگ کاتیونی bluex-5g، red x-grlوyellow x-gl پس از بررسی گستره خطی با نسبت غلظتی متفاوت برای حذف همزمان انتخاب شدند. برای برقراری رابطه مناسب بین جذب و غلظت هر رنگ از روش اسپکتروفوتومتری مشتقی استفاده شد. روش حذف به کار برده شده، با استفاده از جاذب کربن فعال کک انجام شد . ایزوترم های جذبی تک جزیی برای مدل فروندلیچ و لانگمویر، و سه جزیی برای مدل لانگمویر بررسی شدند.
PURPOSE The aim of our study was to characterize and describe the different immunohistochemical expression patterns of cytokeratin 8/18 (CK8/18) in breast tumors and to make a correlation between histopathology, immunohistochemistry for CK8/18 and its possible diagnostic value of this pair of keratins for molecular classification of breast cancers. MATERIAL AND METHODS Forty cases of breast t...
