Objective
To investigate genetic subtypes of inherited bone marrow failure syndrome Fanconi anemia (FA) in Sebia. FA-D2 subtype was found to be the most frequent genetic subtype among investigated FA patients; specific observations of FA-D2 phenotype are pointed out.Methods
Several biological endpoints of FA cells in vitro such as radiation-induced level of lymphocyte micronuclei (radiosensitivity), base line and radiation induced level of the DNA double strand breaks (DSBs), leukocyte apoptosis, and telomere capping function were assessed.Results
The results indicate that all FA-D2 patients display radioresistant in vitro response, which is seen as significantly reduced yield of radiation-induced micronuclei. On the contrary, FA-A patients display radiosensitive in vitro response seen as increased number of radiation-induced micronuclei (MN). A massive elimination of irradiated cells via apoptosis is found in both FA-A and FA-D2 subtypes. In FA-A subtype apoptosis positively relates with the yield of radiation-induced MN, whereas in FA-D2 subtype apoptosis relates with a high percentage of cells carrying dysfunctional telomeres. The present results unequivocally demonstrate that cytokinesis-block micronucleus (CBMN) assay and analyses of telomere capping function can be used to distinguish FA-D2 and FA-A complementation groups.Conclusions
Considering all biological endpoints were analyzed, it can be concluded that all FA patients are radiosensitive, regardless of their complementation group. Thus, using CBMN test and telomere capping function analysis can discriminate FA-A from FA-D2 complementation groups, which could be important for assessment the conditioning regimens prior to bone marrow transplantation. 相似文献2.

We present a very rare congenital immunologic disease, severe combined immunodeficiency syndrome (SCID) in 6-months-old-boy with prolonged mucocutaneous candidiasis, severe anaemia, skin rash similar to the infiltrative eczema of Langerhans cell histiocytosis (LCH) and subcutaneous nodules with histiocytic infiltration. Laboratory findings show profound absence of humoral and cell-mediated immunity. Pathology specimens analysis of subcutaneous nodule revealed numerous S-100 protein and Cd1a negative histiocytes, occupied by BCG intracellular growth. Histopathology and immunohistochemistry confirmed the diagnosis of BCG dissemination. BCG vaccination in infants with SCID can lead to life threatening dissemination, resembling to the infiltrative eczema of LCH and may mislead the clinician. 相似文献

Except in primary effusion lymphoma (PEL), serous effusions with lymphomatous cells in non-Hodgkin lymphoma (NHL) are not frequently seen as first manifestation of disease. In NHL lymphoplasmacytic lymphoma (LPL) the spleen, lymph nodes, and bone marrow are frequently sites of disease and this type of NHL is usually associated with a serum paraprotein of IgM type accompanied by the clinical syndrome of Waldenstr?m macroglobulinemia. Our patient with NHL LPL type presented in this report had less frequently seen involvement of gastrointestinal tract and clinically was first manifested as effusion in Douglas space. Cytological evaluation as well immunoanalyses of effusion in such cases is essential, and various ancillary studies, because of differential diagnostic problems of lymphomas in serous effusions, first include reactive lymphocytoses and small round-cell tumors (SRCT). In our patient, cytology of effusion revealed cytomorphologically atypical lymphomatous cells with plasmocytoid differentiation. Immunocytochemical and flow cytometry analysis confirmed lymphoid cell differentiation and pathohistological diagnosis of CD20(+) LPL was set after pathohistological analysis of resected ileum. 相似文献

FHIT and WWOX are tumor suppressor genes that span the common fragile sites FRA3B and FRA16D, respectively. To analyze possible synergisms among these genes in cervical cancer progression, we considered 159 cervical intraepithelial neoplasias, and 58 invasive squamous cell carcinomas of the uterine cervix. All cases were previously selected as high risk HPV. FHIT and WWOX proteins were examined by immunohistochemistry and their expression was inversely correlated with precancerous vs. invasive lesions. Statistics among biological markers indicated an association between FHIT and WWOX. Protein expression of these two genes was also absent or reduced in cancer cell lines. Thus, WWOX may be considered as a novel important genetic marker in cervical cancer and the association between the altered expression of FHIT and WWOX may be a critical event in the progression of this neoplasia. 相似文献

OBJECTIVES: To present the prevalence of dental caries in postwar Bosnia and Herzegovina (BH). METHODS: A survey focused on dmft and DMFT indices was carried out in four cantons of the Federation of BH in 1997. The dental health of 6- and 12-year-olds was assessed in random samples (n = 238 and 318, respectively). DMFT index in adult population was assessed in clients coming to dental offices in the same area (35-44-year-olds; n = 401). All the subjects were clinically investigated. RESULTS: During the 1991-95 war, all four cantons were affected by the migration of population. The population per dentist ratio considerably increased in three cantons. In 6-year-olds, the average dmft (+/-SD) was 4.9 +/- 4.0, and 86% of the children were affected with dental caries. The average DMFT of 12-year-olds was 6.2 +/- 3.9. On the average, 94% of the 12-year-olds were affected with dental caries. Mean DMFT of adult clients was 15.1 +/- 7.0. Almost every adult (98%) was affected with dental caries. CONCLUSIONS: The dental status in postwar BH is rather poor and the mean DMFT in all investigated age groups may be considered high. The detrimental effect of 1991-95 war on social conditions and the health care system should be considered in explaining such poor dental health. Despite the limitations, the presented data may be used to assess the treatment needs, assure the visibility for dental issues in BH, and help the west European countries to plan dental services for refugees from BH. 相似文献

Atopic dermatitis is a chronic relapsing inflammatory skin disease the incidence of which has been constantly growing in all age groups. Research into the use of naphthalene in the treatment of patients with psoriasis proved its anti-inflammatory and antiproliferative effects as well as a satisfactory remission for months in more than 70% of treated patients with psoriasis. The present study was undertaken to investigate the efficacy of naphthalene in the treatment of patients with atopic dermatitis. According to study results, naphthalene therapy proved efficacious and free from side effects in 20 atopic dermatitis patients. 相似文献

Human metallothioneins are a superfamily of low molecular weight intracellular proteins, whose synthesis can be induced by essential elements (primarily Zn and Cu), toxic elements and chemical agents, and stress-producing conditions. Of the four known isoforms in the human body MT2 is the most common. The expression of metallothioneins is encoded by a multigene family of linked genes and can be influenced by single nucleotide polymorphisms (SNPs) in these genes. To date, 24 SNPs in the MT2A gene have been identified with the incidence of about 1 % in various population groups, and three of them were shown to affect physiological and pathophysiological processes. This review summarises current knowledge about these three SNPs in the MT2A gene and their associations with element concentrations in the body of healthy and diseased persons. The most investigated SNP is rs28366003 (MT2A −5 A/G). Reports associate it with longevity, cancer (breast, prostate, laryngeal, and in paranasal sinuses), and chronic renal disease. The second most investigated SNP, rs10636 (MT2A +838G/C), is associated with breast cancer, cardiovascular disease, and type 2 diabetes. Both are also associated with several metal/metalloid concentrations in the organism. The third SNP, rs1610216 (MT2A −209A/G), has been studied for association with type 2 diabetes, cardiomyopathy, hyperglycaemia, and Zn concentrations. Metallothionein concentrations and MT2A polymorphisms have a potential to be used as biomarkers of metal exposure and clinical markers of a number of chronic diseases. This potential needs to be studied and verified in a large number of well-defined groups of participants (several hundreds and thousands) with a focus on particular physiological or pathological condition and taking into consideration other contributing factors, such as environmental exposure and individual genetic and epigenetic makeup.Key words: metals and metalloids, rs28366003, rs10636, rs1610216, single nucleotide polymorphism 相似文献
