1. Cellular Responses to Cerebral Ischemia during Aging

T.A. Balseanu, Ana-Maria Buga, A. Popa-Wagner

Old age is associated with an enhanced susceptibility to stroke and poor recovery from brain injury, but the cellular processes underlying these phenomena are uncertain. Therefore studying the basic mechanism underlying functional recovery after brain ischemia in aged subjects is of considerable clinical interest. The available evidence indicates that (i) compared to young rats, middle aged rats develop a larger infarct area, as well as a necrotic zone characterized by a higher rate of cellular degeneration, and a larger number of apoptotic cells; (ii) in both old and young rats, the early intense proliferative activity following stroke leads to a precipitous formation of growth-inhibiting scar tissue, a phenomenon amplified by the persistent expression of neurotoxic factors; and (iii) the regenerative potential of the rat brain is largely preserved up to 20 months of age but gene expression temporally displaced, has a lower amplitude, and is sometimes of relatively short duration.

2. Mandibular Panoramic Indexes Predictors of Skeletal Osteoporosis for Implant Therapy

Marina Melescanu-Imre, Elena Preoteasa

The aim of this study is to evaluate the relationship between osteoporosis and mandibular panoramic indexes in order to assess the possibility of using these parameters as an indicator of osteoporosis. Bone quality relates to bone turnover rate, architecture, damage accumulation, and degree of matrix mineralization. Risk factors for osteoporosis can be categorized as no modifiable (sex, age, early menopause, body frame, race, heredity) or modifiable (lack of calcium, exercise, smoking, alcohol, systemic diseases etc). Various studies have demonstrated that individuals with osteoporosis have altered morphology of the mandible and various investigators reported different aspects:  mandibular bone mineral density and cortical index (MCI), mandibular alveolar bone mass, inferior Cortex of the Mandible, alveolar bone resorption, the number of teeth present and special considerations for implant therapy in osteoporotic patients. In conclusion, this paper is a review of the literature on the

3. EUS Elastography in Evaluating Chronic Liver Disease. Why not from Inside?

M. Rimbas, D. I. Gheonea, Larisa Sandulescu, A.Saftoiu, P. Vilmann, T. Ciurea

Fibrosis is the liver’s scarring response to injury, culminating in cirrhosis and its complications. Percutaneous liver biopsy with connective tissue stain is considered more likely a ‘‘silver’’, rather than a ‘‘gold standard’’ for assessing the degree of hepatic fibrosis. That’s why new modalities were recently developed to accurately assess the stage of the liver disease. The term ‘‘elastography’’ describes an imaging technique that conveys information about a tissue’s relative firmness in response to compression, meaning it is more akin to palpation than inspection. Real-time transabdominal elastography represents a new technology for measurement of tissue elasticity integrated in ultrasound systems and can be performed with conventional ultrasound probes during a routine sonography examination. Some of its limitations are that it cannot explore neither all the patients, nor a sufficient size of the liver. In order to overcome these, now that the techno

6. Screening for Cardiac Anomalies During the Early Second Trimester (as part of the Triple/combined Test Ultrasound) – Accomplishments and Limits

A. Comanescu, N. Cernea, Stefania Tudorache, D. Iliescu, R. Capitanescu, Claudia Oprea

Part of the SONOSEROSCREEN PROJECT , we study at the beginning of the first trimester a group of biochemical and ultrasound variables. Regardless the results obtained, all the patients enrolled in this cohort is subject to a second study in the early second trimester that encompasses the dosage of AFP, iA, β-hCG, uE3 an an ultrasound exam targeted at precise biometry and fetal morphology. We tried to evaluate the achievable accomplishments and limits of fetal heart evaluation at 16-20 weeks ultrasound. We evaluated the heart ( four chambers and great vessels) at all patients that came for the early second trimester evaluation (stage II of our study). All patients were reassessed at 24 weeks. Correct heart scanning is possible at the triple test ultrasound (16 – 20 weeks), but needs an experienced sonographer, who masters the Color Doppler, patients and a high end ultrasound machine.

Liliana Novac, Mihaela Niculescu, D. Iliescu, Maria Manolea, Stefania Tudorache, R. Capitanescu , N. Cernea

Introduction. The placental vasculogenesis process appears only in the time of the embryo developement and forms the primar vasculary substratum, the first capillary vessels developing in the days 18 – 20 from the fecundation, phenomena that are necessary for the normal evolution of the pregnancy. At the same time, at the level of the implantation site, the ultrasonographic investigation of the trofoblast has shown specifical changes correlated with the gestational age. Matherial and method. We have investigated 47 pregnant women with the gestational age between 5 and 12 weeks, which had legal abortion on request. The patients were echographically monitored until the time of the curettage, particulary by the trofoblastic thickness at the implantation site. The material resulted after the curettage has been histologically studied, the histological and echographical evaluation of the cases being made according to the gestational age. Results and discutions. It has been accomplished a

8. Stress in cholecyst pathology

Ileana Viorica Dinca

Chronic or acute daily stress, postoperatory or food one represents a risk factor causing the appearance of the cholecystis or acute or chronic cholecyst-pancreatic pathology. The present study focused on the extracell matrix microanatomy from the cholecyst wall, correlated to the storing function of the gallbladder. ”Neuromuscle units” revealed into the cholecyst wall structure, spacial distribution of the microanatomic elements from the vesicular wall and the relationships they have with the extracell matrix structure determine that the cholecyst wall should react as a unitary whole in case of an excessive neurotransmission.

9. Histopathological Study of the precursor Lesions of the Ductal Invasive Breast Carcinoma

Georgiana Luminita Fota, Cristiana Simionescu, Claudia Valentina Georgescu , Nicoleta Patrana , Mihaela Muntean , A. Stepan

The precursor lesions of the ductal invasive breast carcinoma are a heterogeneous group of lesions that raise problems in defining, classifying and diagnosing them. These lesions include the usual ductal hyperplasia, flat epithelial hyperplasia (Ductal Intraepithelial Neoplasia grade 1A), atypical ductal hyperplasia (Ductal Intraepithelial Neoplasia grade 1B), and ductal carcinoma in situ (13, 16). There are three histopathological grades of the ductal carcinoma in situ: low grade (Ductal Intraepithelial Neoplasia grade 1C), intermediate grade (Ductal Intraepithelial Neoplasia grade 2) and high grade (Ductal Intraepithelial Neoplasia grade 3) of malignity (13). We focused on the distribution of the precursor lesions of the ductal invasive breast carcinoma within the pathology of mammary gland, their association with ductal invasive breast carcinoma, the shares of the age categories and sexes, as well as their histopathological study. The predominant lesion of the ductal invasive breast

I.E. Plesea, I. Ivanus, O.T. Pop, Mirela Ghilusi, Claudia Valentina Georgescu, Carmen Popescu, V. Gheorman

Fetal growth is depending on integrity of fetal appendages. The aim of the study was reveal if morphological changes of fetal appendages could be related with the presence of fetal distress (either acute or chronic). Several quantitative parameters, such as placental weight, type of placental pathological process; vascular densities in the placental villi, thickness of umbilical cord vessels’ wall and amniotic membrane thickness were assessed on 20 pacients whose new borns had fetal distress. The results of statistic correlations between those parameters allow us to conclude that umbilical vein wall thickness can affect the vascular density in central placental areas and consequently fetal-placental exchange, resulting in fetal distress.

11. Morphopathologic Features of Fetal Appendages in Fetal Distress

I. Ivanus, I.E. Plesea, V. Gheorman, Anca Ancuta, Corina Cotoi, Fl. Cornitescu, N. Rica

Fetal growth depends on the integrity of fetal appendages. The aim of the study was to reveal the possible correlations between different morphological changes of each of the three fetal appendages (placenta, umbilical cord and amnios) and the presence of one of the two aspects of fetal distress (FD) (acute or chronic). Placental weight and type of fetal appendage pathological process were assessed on 116 patients whose newborns had fetal distress. The results of our analysis allowed us to conclude that umbilical cord pathology was not the main cause of FD as one might think at first sight but placental pathology, which was the main factor in both the intrauterine growth retardation (IUGR) subgroup as placental insufficiency as well as the acute fetal distress (AFD) group as premature detachment of normally inserted placenta (PDNIP). Associations of several pathological processes of fetal appendages were rare, usually leading to the onset of IUGR.

12. Influences Exercised By The Intensity Of The Oxidative Stress Over Wounds Healing In Surgical Therapy Of Breast Cancer

Tudorascu Brujan Iulia, C. Margaritescu, M. Novac, Cristina Simionescu, Camelia Foarfa, Maria Vrabete

The objectives of our study were: Determination of the plasmatic oxidative status over the patients with operated breast cancer (CS). Assessment of the ratio between the intensity of the induced S.Ox (tumour + surgical act) and the plasma antioxidant potential. Evidencing of parameters, allowing elaboration of a prediction with regard the quality of the post-operation wound cure. Methods: We investigated 32 patients with breast cancer (CS) and 37 healthy patients (witness lot), 69 cases, in total. We have calculated the total anti/oxidant potential, of plasma (TAOP), measured the concentration of total peroxides from plasma and calculated the ratio between the two values, which is expressed as an index of oxidative stress (ISO). These values are used in order to appreciate the oxidative status of plasma. We achieved four groups of study, considering the morphopathological aspect of tumours and the prognosis over the quality of wound healing, post-surgery. In order to explain the psycho

13. Dissolution of Pentoxifylline from Extended Release Formulations. Researches Concerning Development of a Biorelevant Test

Georgeta Ionica, F. Radulescu, Dalia Miron, ValentinaAnuta, C. Mircioiu, Ionela Belu

Paper presents results of a pharmacokinetics study concerning pentoxifylline and its main metabolites after administration of extended release formulation of Trental 400 mg and correlation of this pharmacokinetics with in vitro dissolution test results of parent drug. In order to establish most relevant in vitro test, dissolution was performed in different experimental conditions (stirring rate and dissolution medium). Correlation was linear and very good. Generalization of correlation to rate of appearance of metabolites in plasma proved that this process could be well correlated with dissolution. Most relevant test was finally found to be the release in water medium, in conditions of a high stirring rate – 100 rpm.

15. Particularities of Real-Time Polymerase Chain Reaction Technique (RT-PCR) in the Monitoring of Chronic Myeloid Leukemia Patients – A Brief Overview

Kinga Tatar, Hortensia Ionita

Chronic myeloid leukemia (CML) is a myeloproliferative disorder, characterized by a specific chromosomal aberration, the Philadelphia [Ph] chromosome. The Ph chromosome is the result of a reciprocal translocation between the long arms of chromosomes 9 and 22, t (9;22)(q34;q11). The molecular consequence of this translocation is a novel fusion gene, BCR-ABL, which encodes a constitutively active tyrosine kinase, implicated in pathophysiology and development of CML [1,2]. Imatinib mesylate currently the golden standard for front line treatment of CML, is a selective inhibitor of the BCR-ABL tyrosine kinase activity. Responses to imatinib occur at hematologic, cytogenetic and molecular levels. IM therapy now allows the majority of patients with CML to reach CCyR - a confirmed good prognostic indicator [3]. In different studies, 87% of patients in chronic, 17% of patients in accelerated, and 7% of patients in blast phases reached the important clinical aim of Ph negativity [3-5]. Ph chromo

16. More Performing Techniques for Identification of Comitial Focus and their Spreading

D. Faget, D. Georgescu, A. Nestianu, V. Nestianu

By measuring EEG frequencies by Burch method (analysis of periods), determining the exact times of various EEG frequencies, which the specialist sees by visual inspection, we can obtain more precise and certain information regarding the comitial focus than by FFT, as this technique provides wave indexes for each frequency. Frequency analysis by FFT also finds inexistent frequencies on the route, resulted by decomposing in Fourier sequences, and therefore sometimes the result is false. In order to observe the spreading of ample, super-voltage comitial-type discharges on the cerebral cortex, an original technique was implemented, which determines graphically by maps the time measured in milliseconds in which the comitial wave spreads on the cerebral cortex (time mapping).
