Since some involve the skin, either primarily or as part of their systemic manifestations, we have tried to briefly examine some of the cutaneous conditions related to IgG4. The mandate for a proper preservation in histopathological tissues Maria Comanescu, D.

Arsene, Carmen Ardeleanu, G. Bussolati A sequence of technically reproducible procedures is mandatory to guarantee a proper preservation of tissues and to build up the basis for sound diagnoses. However, while the goal of these procedures was, until recently, to assure only structural histological and cytological preservation, an appropriate preservation of antigenic properties and of nucleic acid integrity is now additionally requested, in order to permit pathologists to provide the biological information necessary for the adoption of personalized therapies.

Positive diagnosis can only be made after histopathological analysis and immunohistochemical analysis in rectal cancer pathology. The bioptic material rectal cancer pathology sampled by rigid endoscopy this being the only viable method of assessing data on the tumor prior to the surgery.

Several risk factors influence the biology of this site thus inflicting both cellular and molecular modifications that are the origin of cancer development. Natural products locally modulators of the cellular response: therapeutic perspectives in skin burns G. Parvanescu, I. Lascar Local cellular response plays a major role in restoring skin integrity, in burns with infectious complications, chronic fibrous sequelae, etc. For the study of wound-healing process, different experimental models of skin burn were developed.

Mice, rats, rabbits and guinea pigs are the most used laboratory animals, kept under standard conditions of light, temperature, food and water ad libitum. Commonly, by intramuscular injection, general anesthesia was induced with ketamine hydrochloride. Most times, skin burns were inflicted on the dorsal region of animals.

For quite some time, anal canal cancer rectal cancer was not regarded as an individual pathology, but it was seen, instead, as a form of rectal cancer. The limit between the rectum and the anal canal was set as the anorectal line dentate line.

Nuclear changes were consistent with sarcoplasmic alterations. Changes of the interstitial connective tissue were sometimes extensive and sometimes barely noticeable.

The most common alteration of this structure was the onset and development of a mainly perivascular collagen fibrillogenetic process. Mogoanta, F. Secureanu, A. Olaru, Carmen Neamtu, B. Totolici, M. Ionila, Stefania Craitoiu Colorectal cancer is an important public health problem worldwide, being the fourth most common cancer in men and the third most common in women.

Colorectal cancer incidence is higher in developing countries due to the prevalence of obesity associated with reduced physical activity.

Rectal mucinous carcinomas, especially the "signet ring cell" type, have a worse prognosis compared with other varieties of colorectal carcinomas, being rectal cancer pathology in more advanced stage and more prone to lymph node and peritoneal metastases. Our study comprised 37 cases with rectal adenocarcinoma with mucinous component operated in the Surgical Clinics of the Rectal cancer pathology County Hospital of Craiova, between and The aim of this study was to evaluate some molecular prognostic factors for rectal mucinous carcinomas namely B-cell lymphoma 2 Bcl-2 and epidermal growth factor receptor EGFRand their correlations with the main morpho-clinical parameters of these patients.

Thus, we immunohistochemically assessed the degree of apoptosis of tumor cells in mucinous rectal carcinomas using the Bcl-2 marker, and tumor aggressiveness using the EGFR responsiveness.

The evaluation of tumor aggressiveness in terms of EGFR responsiveness showed a reduced expression in carcinomas correlated with the increase in quantity of the mucinous component. In addition, EGFR reactivity was increased in the tumor invasion front.

TheTerminologia Anatomica homologates two branches of the renal artery anterior, posterior and five segmental arteries: four from the anterior branch and one from the posterior one. The purpose of this study is to evaluate the renal artery branching pattern, the number and origin of the segmental arteries, as well as to review data from similar studies. The study material consisted of 60 formalin-fixed adult kidneys. Dissections and microdissections were performed on the renal arteries and their branches.

The branching of the renal artery was prehilar in Type I trunks are those that originate directly from the main renal artery.

Apr, Vol.

They divide either into segmental branches, or into just branches and a smaller trunk type II. The type II trunks further divide into other segmental branches. These common trunks must be taken into account to avoid confusion with the segmental arteries. Knowledge of these variations is useful not only morphologically, but also clinically.

Chronic gastritis with intestinal metaplasia: clinico-statistical, histological and immunohistochemical study Rodica Dirnu, F. Rectal cancer pathology, Carmen Neamtu, B. Totolici, O. Pop, P. Mitrut, D. Malaescu, L. Mogoanta Chronic gastritis has a high incidence in adults, causing progressive destruction of glandular structures, favoring the development of gastric atrophy.

The association of chronic gastritis with intestinal type metaplasia of gastric rectal cancer pathology has a poor outcome as intestinal metaplasia is regarded as a precancerous lesion. Metaplasia is common in patients with Helicobacter pylori infection and also heavy smokers. The aim of our study was to evaluate the relationship between rectal cancer pathology gastritis and intestinal metaplasia. The study was conducted on a total of patients, aged between 5 and 90 years, who presented for dyspeptic disorders in the period and were examined clinically and endoscopically.

During the gastroscopic examination, fragments of gastric mucosa were collected for the histopathological study and for highlighting the H. A diagnosis of gastritis was established in patients, representing approximately Most cases with gastritis were found in people of middle age. Gastritis was present in almost all age groups, from teenagers to the elders. Of the cases of gastritis, urease test was positive in patients, representing approximately Histopathological examination identified the presence of intestinal metaplasia in PCNA immunohistochemistry revealed that cell proliferation processes are intensified in intestinal metaplasia.

This study highlights the importance of chronic gastritis, intestinal metaplasia, and H. Cellular immunophenotypes in human embryonic, fetal and adult heart Alina Grigore, D. Arsene, Fl. Ceausu, Maria Comanescu, Florica Staniceanu, Rectal cancer pathology Ardeleanu The cellular immunoprofile of cardiac dysfunctions and lesions of ischemic etiology are insufficiently studied to date, especially regarding the contribution of non-cardiomyocytic structures.

Aiming to explore this immunoprofile, we used immunohistochemistry applied on embryonic, fetal and adult normal or ischemic myocardium. We observed a decrease of smooth muscle alpha-actin expression in fetal vs. DDR2 and vimentin, which are present in the interstitial cells and cardiomyocytes of the rectal cancer pathology, fetus and normal adult heart, are absent in the fibrotic scar tissue and cicatricial infarction, the latter expressing smooth muscle alpha-actin and CD This suggested that myofibroblasts and not local fibroblasts that participate in ischemic remodeling.

An EGFR-positive vascular network was better represented in the ischemic heart rectal cancer pathology in the paraziti bube normal one, a fact possibly related to EGFR implication in cardiac ischemic pre- and post-conditioning. Therefore, cardiomyocytes and non-cardiomyocytic cells have an undulating rectal cancer pathology according to the intrauterine life stage or age after birth, and a variable contribution in cardiac lesions, mostly in ischemic ones.

Acinic cell carcinoma of the salivary glands: a retrospective clinicopathologic study of 12 cases Maria Cristina Munteanu, Cl. Margaritescu, Rectal cancer pathology Cionca, N. Nitulescu, Luminita Daguci, E. Ciuca Acinic cell carcinoma ACC is the third most common epithelial malignancy of the salivary glands in adults, with a low-grade malignancy that mainly occurs in the parotid gland and at a relatively younger age than other salivary gland tumors.

We made a retrospective study on our acinic cell carcinoma casuistry aiming their clinico-pathological characterization and comparison with literature data.

Loco-regional Advanced Colorectal Cancer: Diagnostic and Therapeutic Features

From through in our hospital were diagnosed only 12 cases of ACC. The clinico-epidemiological study revealed prevalence of these tumors in women, in the fourth decade of life and especially occurring in the parotid gland. Summing all these clinicopathological features, we conclude that for our casuistry the biological behavior of these tumors has been of low-grade malignancy. Effect of prenatal administration of therapeutic doses of topiramate on ossification of ribs and vertebrae in rat fetuses R.

Fadel, R. Sequeira, M. Abu-Hijleh, M. Obeidat, A. Salem There are few studies that have addressed the effects of prenatal exposure of topiramate on ossification of the bones derived from the paraxial mesoderm. This study aimed to evaluate skeletal ossification of ribs and vertebrae in day-old rat fetuses after maternal exposure to two therapeutic doses of topiramate.

Topiramate was administered by gavage from day of gestation.

Fetuses were collected on day 20 by caesarian section. Fetal bones were stained with alizarin red and ossification was assessed. Results showed significant delayed ossification of ribs and vertebrae in topiramate-exposed fetuses at both doses and the effects were not dose dependent. In all examined groups, there was a direct correlation between the fetal weight and the number of complete ossified vertebral centers. Also, there were significant increases in skeletal abnormalities, particularly in ribs in both treated groups when compared to the control group.
