We evaluated the use of the leukocyte esterase test (LET) on first-catch urine specimens from women as a screening test to predict infection with Chlamydia trachomatis. For diagnosis, we used Abbott's ligase chain reaction (LCR) on urine specimens and isolation by tissue culture (TC) on cervical brushes. Of 4,053 women attending sexually transmitted disease and family planning clinics, 4.3% (n ...

BACKGROUND Total joint arthroplasty (TJA) has been one of the most rewarding interventions for treating patients suffering from joint disorders. However, periprosthetic joint infection (PJI) is a serious complication that frequently accompanies TJA. Our study aimed to investigate the application of the leukocyte esterase (LE) strip in the diagnosis of PJI. MATERIAL AND METHODS From October 2014...

tetranychus urticae koch is an important and destructive pest of crops, fruits and ornamental plants in worldwide. the high fecundity of t. urticae and its abruptly life span as well as the extensive application of acaricides for keeping t. urticae damages below economic injury level, caused to resistance to acaricides and control failures. in this research the fumigant activity of essential oi...

Naphthyl esterase and platelet-activating factor (PAF)-acetylhydrolase activities were detected in the salivary glands of the cat flea, Ctenocephalides felis. Salivary naphthyl esterase activity is disgorged during exploratory probing. Whole extracts of salivary glands contain esterase activity against the short-chain naphthyl esters alpha-naphthyl acetate (approximately 210pmol/min/gland pair;...

Studies on an esterase derived from partially purified preparations of the first component of complement are described. The esterase hydrolyzed certain synthetic amino acid esters, among which N-acetyl-L-tyrosine ethyl ester was most susceptible. This was hydrolyzed maximally between pH 7.5 and 8.2, and at 41 degrees C. The esterase could not be identified with other previously described hydrol...

By J. FRE!, CL. BOREL, G. HORVATH, B. CULLITY AND A. VANNOTFI I ODAY it is known that the leukocyte possesses a very complete enzymatic equipment. As well as the systems connected with its special functions, the majority of the fundamental cellular processes are represented in the white cell, as is shown in the monograph on the metabolism of the leukocyte written by Bazm and Delaunay.’ However,...

OBJECTIVE To determine the effects of very weak, extremely low frequency (50 Hz) electromagnetic field (ELF-EMF) on the relative spleen weight, lymphoid organ histology, peripheral blood leukocyte and alpha-naphthyl acetate esterase positive (ANAE- positive) lymphocyte percentages of the mouse. METHODS The study was carried out in Scientific Research and Application Center of Selcuk Universit...

BACKGROUND Acute myeloblastic leukaemia is a malignant bone marrow neoplasm of myeloid precursors of white blood cells. Due to its high morbidity rate, early diagnosis and appropriate medical therapy is essential. METHODS The article highlights normal blood alterations like anaemia, thrombocytopenia, leukocytosis and advanced diagnostic aids like flow cytometry, special staining as a diagnost...

To study the cellular basis for specific antigen-induced leukocyte adherence inhibition, enriched populations of B-cells, T-cells, and monocytes were prepared by a two-stage adherence separation procedure from spleen cells of normal C57BL/6J mice and mice bearing progressively growing MCA-38 tumors. The reactor cell undergoing specific antigen-induced adherence inhibition was identified as a mo...
