It is really important to select irrigating fluids in transurethral resection of prostate. Some factors use to evaluate irrigating fluids, disolve of plasma, the absorption of irrigating fluids on blood circulation, half waist duration in plasma and metabolism factors arise, toxic or nontoxic for body. Some irrigating fluids used in transurethral resection: mannitol, sorbitol, glycin. These fluids are not consider as unfully isotonic

Lycopen - a carotenoid extracted from tomato had antioxidant effect stronger than other carotenoids, lowered the risk of cancer, especially prostate cancer/arteriosclerosis and delayed the development of prostate cancer. When heating tomato into viscous mixture, biological efficacy of lycopen is stronger than raw tomato or tomato juice. This efficacy is stronger when using lycopen combined with some carotenoids such as vitamin E and beta-carotene

The best way for development of urological profession in the first decades of 21st century is to closely collaborate between researchers and clinicians in finding the solutions and new methods of treatment. The first step is to evaluate the basic available conditions and knowledge. From which to introduce the ways for changing and developing the urological profession.

Background: Non-Hodgkin's lymphoma is a malignant (cancerous) growth of B or T white blood cells (lymphocytes) in the lymph system. Many lymphoma classifications were proposed. All were based by groups of the original cells, histopathological appearances and clinical features. Purpose: Histological classification of lymph node malignant non - \r\n", u'Hodgkin lymphoma based on the new WHO 2001 classification. Objectives: To apply new WHO 2001 classification of 165 cases of malignant non Hodgkin lymphoma were histopathologically and immunohisto chemically studied at K hospital in Hanoi. Subjects and method: The study included 165 patients with malignant non Hodgkin lymphoma were examined and treated at K hospital in Hanoi from 2000 to 2003. Results: The study based on new WHO 2001 classification of 165 cases of malignant non Hodgkin lymphoma showed results B lymphoma: Diffuse large B - cell lymphoma accounts for 63.3%, follicular lymphoma: 17.5%, small lymphocytic lymphoma: 12.5%, mantle cell lymphoma: 1.7% and the others are at low rate. T lymphoma: large T-cell lymphoma accounts for 35.0%, T lymphoblastic lymphoma: 30.0%, angioimmunoblastic T-cell lymphoma: 12.5%, peripheral T- cell lymphoma, unspecified: 10.0%, the others are at low rate. Conclusion: We concluded that new WHO classification of malignant non Hodgkin is reproducible in our practice and should be useful in the treatment decision. \r\n', u'

Background: Large lymph-node is clinically common sign. However, in some cases, it is difficult to diagnosis by staining method routinely. Objectives: To classify of lymph node lesions by histopathological and immunohistochemical study. Subjects and methods: 1860 cases carried out lymph node biopsies at K Hospital were histologically and immunohistochemically analyzed. Results: The most common lesions were lymph node metastasis (35.25%) chronic lymphnoditis (20.82%), tuberculous lymphnoditis (19.42%) and non Hodgkin lymphoma (18.62%). Histological typing of metastasis revealed that the most frequent types were undifferentiated carcinomas (28.13%), squamous carcinomas (23.7%), adenocarcinomas (16.97%) and type-unspecified carcinomas (13.3%). Non Hodgkin lymphoma rate was higher than that of Hodgkin lymphoma (86.06% versus 12.8%). Immunopheotype of non Hodgkin lymphomas showed that 79.71 % were B cell type, 18.15% were T cell type and 2.14% were Ki-1 type. The most common types of B cell lymphomas were diffuse large B cell lymphomas (35.57%), follicular lymphomas (25.9%) and diffuse small B cell lymphomas (13.83%), The most common types of T cell lymphomas were lymphoblastic T cell lymphomas (41.8%)., large T cell lymphomas (23.53%) and unspecified periphery T cell lymphomas (11.76%). Conclusion: Immunohistochemical analysis of metastasis allowed identifying immunophenotypes of different types of metastatic carcinoma and melanoma and evaluating the origin of unknown primary metastasis. \r\n', u'\r\n', u'\r\n', u'
