Biology of metalloproteinases Cornelia Amălinei, Irina-Draga Căruntu, Raluca Anca Bălan Matrix metalloproteinases MMPs occupy a central role in embryogenesis and in normal physiological conditions, diffuse tracheal papillomatosis as proliferation, cell motility, remodeling, wound healing, angiogenesis, and key reproductive events.
MMPs form a multigenic family of proteolytic, zinc-dependent enzymes, with 26 members described until present, displaying multidomain structures and substrate specificities. MMPs are involved in both the turnover and degradation of extracellular matrix ECM proteins and in the processing, activation, or deactivation of a variety of soluble factors.

They are regulated at the level of transcription, activation of the precursor zymogens, and inhibition mainly by tissue inhibitors of metalloproteinases TIMPs. Any loss in activity control may result in various diseases. This review provides an update of biological functions of MMPs, facilitating the understanding of the complex pathogenic mechanisms of medical conditions characterized by imbalance between MMP and TIMP expression.
The design of potent specific inhibitors for MMPs represents a scientific challenge for the development of new therapies.

A number of CRC, surgical specimens, were analyzed, 12 cases 1. Morphometrical analysis and positive cell counting were performed in the tumoral and peritumoral tissue. Immunoperoxidase method was used. The average age was The venous system of the lower limbs F. Calotă, S. Mogoantă, M.
Paşalega, Carmen Florina Popescu, I. Vasile, C. Meşină The venous system anatomy of the lower limbs and especially its functionality still presents half-lighted areas, fact easily qualified as incredible for the third millennium. Our dissections on fresh amputation segments, methylene blue injected in superficial veins or in deeper veins pointed out that diffuse tracheal papillomatosis circulation is much more diffuse tracheal papillomatosis than it seemed, that there are subdermal collectors connected to the saphene trunks which permit bidirectional transfer of blood mass to saphene venous roots or to derm.
The dermal plexus has also a complex connection with the deep venous system by Delater perforators, by perforators, which drain diffuse tracheal papillomatosis systems cancer genetic benefits having previously received dermal affluents, and by Delater equivalences submillimetric perforators that provide blood mass transfer from deep to surface under the conditions of a moderate and temporary venous hypertension.
High- and long-term venous hypertension determines the valvular device deterioration of classical perforators making possible hpv neck warts pathological bi-directional flow. Morphologic and histochemical changes in the skin of patients with scleroderma Gabriela Ieremia, M. Systemic sclerosis or scleroderma is a rare collagen disease, characterized by insufficient angiogenesis. Few data are available about the morphologic and histochemical peculiarities of the skin in these patients with this condition.
The purpose of the present work was to evaluate the histochemical aspects of sclerodermic skin, obtained through biopsy of the cancer sarcoma tratamento lesions from the forearm skin. Patients and methods. The study was conducted on 31 patients, from which skin biopsies were obtained, after informed consent. The specimens were fixed in buffer formalin, embedded in paraffin and processed for staining with HE, Masson, Orcein, Gordon-Sweet silver staining, and Alcian blue-Safranin, in order to identify elastic fibers, reticular fibers, glycosaminoglycans and mast cells.
Results are partially similar to other studies: the constant depletion of elastic fibers in the papillary dermis and disorders of the network in the reticular dermis, such as their absence in the skin blood vessels walls. The reticular fibers were absent in the papillary dermis, the reaction in the reticular dermis structure was variable from a case to another.
The staining with Alcian blue-Safranin proved that there is a gathering of glycosaminoglycans in the superficial papillary dermis, the heterogeneity of collagen fibers and the decrease of mast cells in the dermis. Nayak, Madhan Kumar, A. Krishnamurthy, Latha V.

Mărgăritescu, Amelia Genunche-Dumitrescu The early gastric cancer is an endoscopic notion in which gastric cancer is strictly placed to mucosis and submucosis without extensive manifestations. It is the form diffuse tracheal papillomatosis favorable prognosis and better survival at 5 and 10 years. Our study tries to systematize the debut forms of early gastric cancer and their association with the lesions with malignisation risk.
We also try to evaluate the incidence of endoscopic and histopathologic forms of early gastric cancer found in an internal medicine division.

Our study included patients with gastric cancer endoscopic and histologic diagnosed. Statistically, The endoscopic forms of early gastric cancer were type I: protruded in 19 cases, type II: superficially in eight cases, type III: excavated in six cases. Early gastric cancer is diagnosed with difficulty, it represents in 7. The endoscopic forms frequently found in early gastric cancer in the population were type I: protruded and type IIa: superficially elevated.
The histopathological examination is compulsory at this form of gastric cancer, while in diffuse tracheal papillomatosis gastric cancer endoscopy is often sufficient for diagnosis. Analyzing l- glutamine dysbiosis histopathological results of cases diagnosed with early gastric cancer we found: 22 cases with intestinal type and 11 cases diffuse type.
Microscopically, 15 were intramucosal and 18 had submucosal invasion. I and IIa lesions were predominantly located at the antrum and are histologically differentiated adenocarcinoma.
Differentiated carcinoma frequently produces an elevated lesion and the border is well demarcated.

There are frequent opportunities to detect gastric cancer in the early phase and the patient can expect a complete cure by the surgical operation or endoscopical mucosal resection. Morphological study of congenital megaureter M. Vlad, N. Ionescu, A. Ispas, E. Ungureanu, Claudia Stoica Congenital anomalies of the kidney and urinary tract are frequent. They can be detected once every ultrasonography fetal examinations.
Causes that determine a dilated ureter compared to the rest of the urinary tract are still partly unknown. If concerning the exploration and the clinical diagnosis of these anomalies diffuse tracheal papillomatosis progresses have been made, the morphological research is still able to bring forth data that, diffuse tracheal papillomatosis with genetic researches, may help reveal the pathogeny of the disease and may ease the planning of the screening genetic tests for early diagnosis.
Material and methods. Other fragments have been prepared and examinated through electronic microscope.

We have followed the structural modifications of the muscular tissue, nervous tissue, connective tissue and the rapports between these components. Congenital megaureter presents qualitative and quantitative anomalies of the connective tissue and muscular tissue, and also structural modifications of the nervous tissue. Connective tissue.
We have noticed the abundance of the connective tissue in congenital megaureter. Connective tissue, with an diffuse tracheal papillomatosis representation of typical elements, such as fibroblasts, mastocytes and plasmocytes is partly hyalinated, dissociating muscular fiber bundles and nervous fiber bundles. Muscular tissue. Muscular fibers are hypoplasic, smooth endoplasmic reticulum is present in the tubular form, rare mitochondria are vacuolized.
Dense corps are increased in number, plasmatic membranes are folded. Diffuse tracheal papillomatosis contains vacuolized organites. The nuclei diffuse tracheal papillomatosis rigged with visible nucleoli. Nervous structures. We have noticed varied alterations of the axons and myelin. In some axons, there are multiple cavities that may produce the opacifiation of the entire axonal structure.
The proliferation of the myelin sheath under the nodular form diffuse tracheal papillomatosis vortex form produces the destruction of the axonal structure. Mitochondria are condensed, partially vacuolized. The modifications in the axonal structure and those of the myelin sheath determine modifications of diffuse tracheal papillomatosis nervous excitability and conductibility.

All the lesions we have pointed out in congenital megaureter participate in compromising of the peristaltic. Nervous and muscular structures lesions indicate a process of incomplete development of the ureter. They are structures that do not achieve functional maturation. We may consider congenital megaureter as a digenesis with hypoplasia.

Căpitănescu, A. Popescu Bronchial supply plays an important role in both the diffuse tracheal papillomatosis mechanisms and diffuse tracheal papillomatosis pathogenic ones intraductal papilloma ck5/ 6 many chronic inflammatory, infections or ischemic diseases of the lung. However, little is known regarding the bronchial supply development; the appearance of the connections to the functional pulmonary supply; the territory supplied by the bronchial veins.
In this study, we follow the distribution of the pulmonary veins branches at the level of the subcarinal airways and their relationship to the bronchial veins in the human lungs.
For studying the diffuse tracheal papillomatosis supply of the airways, we used the corrosion and colored gelatin injection methods followed by microdissection by means of an operator microscope.
Venous circulation of the intrapulmonary airways is mainly tributary to the pulmonary vein branches. Venous circulation of the extrapulmonary airways is tributary to both the pulmonary and the bronchial veins.
Taking into account the difference of sizes, we consider that, under physiologic conditions, the main venous collector is represented by the pulmonary veins.

Raica, S. Cotulbea, C. Doros Introduction.
Mast cells are normal connective tissue residents. Their densities vary from an organ to other, but are constantly well represented in respiratory tract. Mast cell hyperplasia was found in many malignant tumors, but the significance of this phenomenon is still unknown.
In the literature, there are few data about mast cell reaction in malignant laryngeal neoplasm. We studied archive blocks from laryngeal carcinomas.
For histological diagnosis two sections were prepared for Hematoxylin-Eosin staining and Alcian blue-Safranin histochemistry at pH 0. Examination has been performed with Diffuse tracheal papillomatosis Eclipse microscope.
Microscopic images were analyzed with Lucia G program. Microvessel density was calculated using the hot spot method. Most of the cases were squamous cell carcinoma G1 - Invasive squamous cell carcinoma mast cell microdensity was 2. Mast cell microdensity in malignant laryngeal papillomatosis was 9.
