V souboru 39 případů adenokarcinomu in situ děložního hrdla byly sledovány: věk pacientek, cytologické, kolposkopické a histologické nálezy, operační výkony a definitivní řešení. Medián věku byl 38 let (24–75). Prebioptická suspekce žlázové léze byla vyslovena v 7 cytologických (18 %) a v 7 kolposkopických (18 %) nálezech. U 28 nemocných (72 %) byla současně přítomna koexistující skvamózní léze. V 16 případech (46 %) z 35 konizací byly popsány histologicky pozitivní okraje léze a u 15 z nich byl proveden opakovaný nebo definitivní operační výkon. V něm byl ve 2 případech již invazivní adenokarcinom. Klíčová slova: adenokarcinom in situ – cytologie – děložní hrdlo – kolposkopie – pozitivní okraje, In a series of 39 cases of adenocarcinoma in situ of the uterine cervix, age of patients, cytological, colposcopical and histological findings, operations and definitive solutions have been analyzed. Median age was 38 (24 – 75). Praebioptic suspicion of a glandular laesion was expressed in 7 cytological (18 %) and 7 colposcopical (18 %) findings. In 28 patients (72 %) the coexistent squamous laesion was concurrently present. In 16 cases (46 %) from 35 conisations histologically positive margins were described and in 15 of them repeated or definitive operation was performed. Among them, in 2 cases invasive adenocarcinoma was present. Key words: adenocarcinoma in situ – colposcopy – cytology – positive margine – uterine cervix, and doc. MUDr. Pavel Freitag, CSc.
The ascorbic acid (AA) concentration in anterior pituitary and blood plasma was measured by the Roe-Kuether method in control rats and rats treated with oestradiol benzoate alone, methylene blue alone and with both oestradiol and methylene blue. We have found that methylene blue alone caused a significant drop in hypophyseal both AA and plasma AA concentrations. Methylene blue treatment prevented the increase in plasma AA concentration in oestradiol benzoate-treated rats.
Hyperparatyreóza (HPT) patří k onemocněním, jejichž incidence stoupá. Převážnou většinu primárních hyperparatyreóz (asi 80 %) tvoří adenomy. Karcinom příštítných tělísek je velmi vzácný. K lokalizaci adenomů příštítných tělísek se standardně používá ultrasonografie, scintigrafie, nejčastěji 99mTc-MIBI a CT. Při stanovení diagnózy primární hyperparatyreózy je operační výkon standardním léčebným postupem. Nezastupitelné postavení má peroperační ultrasonografie. V průběhu tří let bylo na našem pracovišti operováno celkem 21 pacientů s diagnózou adenom příštítného tělíska, který byl histologicky potvrzen u 19 pacientů. Náš malý soubor operovaných pacientů vykazuje úspěšnost 90,5 %., Hyperparathyreosis is one of the diseases whose incidence has been increasing. Vast majority of hyperparathyreosis (about 80 %) is made up by adenomas. Carcinoma of parathyroid glands is very rare. Ultrasonography, scintigraphy, most frequently 99mTc-MIBI and CT are standardly being used for localization of the adenomas of parathyorid glands. Operation is a standard medical method in the process of determinating the diagnosis of primary hyperparathyreosis. Peroperative ultrasonography has irreplaceable position. 21 patients with diagnosis of adenoma of parathyroid glands which was histologically confirmed in 19 patiens have been operated in our workplace during three years. Our small aggregate of operated patients shows success rate 90,5 %., Luděk Hnízdil, Iva Procházková, Václav Jedlička, Jan Žák, Jan Kalač, Jan Wechsler, Ivan Čapov, and Literatura
Four mouse bone marrow or thymus cell populations, namely granulopoietic/monocytopoietic, erythropoietic, B-lymphopoietic, and T-lymphopoietic precursor cells have been assayed by RTPCR technique for the presence and relative amounts of adenosine A1, A2a, A2b, and A3 receptor mRNA. It has been found that (i) all four populations studied express all four adenosine receptor subtypes, (ii) the A1 receptor is the least expressed in all populations studied, (iii) the A3 receptor is markedly expressed in the populations of granulopoietic/monocytopoietic and erythropoietic cells, (iv) the A2a receptor is markedly expressed in the populations of B-lymphopoietic and T-lymphopoietic cells, and v) the A2b receptor does not predominate in any of the precursor cells studied. Our data offer a new possibility for the assessment of the readiness of these cells to respond, by receptor-mediated mechanisms, to adenosine or its analogs present in the tissues as a result of endogenous processes and/or following their administration., D.

Expression of mRNA for adenosine receptor subtypes A1, A2a, A2b, and A3 in normal and lipopolysaccharide (LPS)-activated murine RAW 264.7 macrophages has been investigated using the method of quantitative real-time polymerase chain reaction. The results have shown a very low, unquantifiable expression of adenosine A1 receptor mRNA in both normal and LPS-activated macrophages. The other three adenosine receptor mRNAs have been found to be expressed at various but always quantifiable levels. Activation of the macrophages by LPS induced upregulation of the expression of adenosine receptor A2a and A2b mRNA, whereas the expression of adenosine receptor A3 mRNA was downregulated. Unstimulated macrophages exhibited a high expression of the A2b adenosine receptor mRNA. The findings are discussed from the point of view of the antiinflammatory and hematopoiesis-stimulating roles of the adenosine receptor signaling., D. Štreitová ...
