ADRIANA FLORENTINA CONSTANTINESCU, MIHAELA IONESCU, I. ROGOVEANU, C.C. VERE, V.F. IOVANESCU, C.T. STREBA, M.E. CIUREA

Wireless capsule endoscopy is one of the most recent investigation techniques of gastrointestinal pathology. Unlike conventional upper and lower endoscopy, it has the advantages of being a noninvasive and painless procedure. One of the capsule endoscopy disadvantages is represented by the necessary time to analyze the video frames obtained. Software applications proposed in this purpose could offer support in the images evaluation. Different algorithms have been described in the literature, but further research is needed to establish the practical value of computer vision tools in gastroenterology.

MAGDALENA MARIA MANOLEA, ANDA LORENA DIJMARESCU, SIMONA NEAMTU, D.O. ALEXANDRU, R. RICA, A. GOGANAU, LILIANA NOVAC

15-20% of all known pregnancies progress with a miscarriage or an ectopic pregnancy. The recurrent miscarriage is a delicate clinical situation because with all the advances in genetic and immunologic research the incriminating factors have not been discovered yet. The treatment is also subject to controversies, being perceived as either ineffective or aggressive. A number of 376 pregnant women with a gestational age smaller than 12 weeks have been selected, 226 of them with spontaneous abortion. In the study group of patients with previous spontaneous abortions we have found a series of associated pathology. From the cases with secondary non idiopathic recurrent miscarriage we have identified 4 cases of thrombophilia with antiphospholipid syndrome, 2 cases of thrombocytosis, one case of autoimmune thyroiditis, one case of uterine tumor, one case of MTHFR C homozygous thrombophilia and one case of FVL heterozygous thrombophilia. Knowing the correlations between the recurrent miscarriag

ANGELA GABRIELA POSTOARCA, MIHAELA IONESCU, ALICE PIPEREA-SIANU, I. SARBU, LAVINIA GEORGETA HINESCU

Purpose of the paper was the optimization of mobile phase in natrium chloride gradient in the chromatographic separation of butyrylcholinesterase from human plasma. Materials/Methods. Butyrylcholinesterase (BuChE) was isolated from human plasma using a diethylamminoethyl-cellulose column, by elution with 0.02M acetate buffer pH=4.0, gradually increasing NaCl percentage from 10% to 80%. The procedure lasted approximately 28 days. Results. Absorbance of the successive collected fractions at 280 nm presented a maximum at 60 % NaCl concentration. Activity of obtained BuChE was maximum at the same concentration. Another observed effect of NaCl was the decrease of resistance of the column to flow of the elution fluid. In the absence of NaCl the flow rate was 7 mL/h. Increasing of NaCl concentration induced a continuous increase of the flow to a value of 21 mL/h at 60% NaCl solution. After this concentration the flow remained practically constant. The effect on the ionic exchange is essential

14. Correlation between Tgf-Β1 and Fsp-1 Expression in Chronic Viral Hepatitis - an Immunohistochemical Study

DANIELA ELISE TACHE, S.G. FIRU, ANA MARINA ANDREI, ANCA PREDESCU, STEFANA OANA PURCARU, AMELIA MIHAELA DOBRESCU, ANICA DRICU, CATALINA PISOSCHI, ELENA CAMELIA STANCIULESCU

Infection with hepatitis C virus (HCV) is the most important stimulus for chronic hepatitis and subsequent progression to cirrhosis and hepatocellular carcinoma. Fibrosis that follows inflammation represents the main complication. One of the mechanisms that could be associated with development of liver fibrosis is epithelial-mesenchymal transition (EMT). Transforming Growth Factor β1 (TGF-β1) is an important mediator of fibrosis and also able to trigger phenotypic changes in EMT. Fibroblast-specific protein 1 (FSP-1), a marker of fibroblasts in organs undergoing tissue remodeling, is used to identify cells that derive from EMT. In this study, we assessed the expression of TGF-β1 and FSP-1 in liver biopsies obtained from HCV-infected patients using immunohistochemistry and correlated them in order to evaluate the relation between fibrosis and EMT in liver disease progression. Staining of liver sections revealed increased amount of type III collagen and clusters of inflammatory cells

LOREDANA ELENA STOICA, MADALINA VOICULESCU, CLAUDIA CIRSTEA

Dermoscopy is an important in-vivo, non-invasive diagnostic technique that allows visualization of morphological features not macroscopic visible. It has a major contribution in enhancing the diagnostic accuracy for pigmented skin lesions. Recent studies have shown that it also aids in the diagnosis of non-pigmented keratinizing skin lesions, including actinic keratosis and Bowen’s disease. We performed a retrospective study in Dermamed Clinic Craiova, between January and June 2014, with the aim to correlate the dermoscopic and histopathological aspect of skin tumors. This study included a total of 74 patients, aged between 16 and 76 years. The dermatoscopic examination revealed 12 skin cancers, 51 precancerous lesions and 11 benign tumors. Those 12 subjects diagnosed with malignant tumors by dermatoscopic examination, had also histopathological examination and confirmation of the diagnosis, also 11 patients identified with benign tumors with dermatoscopic examination were subsequent
