1. Estudo da susceptibilidade de camundongos bons ou maus respondedores para inflamação aguda a neurotoxinas empregadas em modelos de Parkinson. / Susceptibility of mice genetically selected for acute inflammatory reactions to neurotoxins used in Parkinson´s disease models.
Estudos apontam a neuroinflamação como um dos possíveis agravantes do mal de Parkinson. Aqui investigamos a susceptibilidade de duas linhagens de camundongos selecionados quanto a suas capacidades de produzir alta (AIRmax) ou baixa (AIRmin) resposta inflamatória aguda aos agentes neurotóxicos 1-Metil-4-Fenil-1,2,3,6-Tetrahidropirimidina (MPTP) (Tratamen

2. PRECONDITIONING OF ORGAN DONORS WITH LOW LEVELS OF CARBON MONOXIDE REDUCES GRAFT IMMUNOGENICITY AND IMPROVES LONGTERM ALLOGRAFT FUNCTION
Background: Chronic rejection remains the major obstacle for successful transplantation, and to date there is no effective treatment. Events occurring prior to organ transplantation such as brain death, harvesting procedure, and ischemia-reperfusion injury lead to unspecific inflammatory damages danger signals - that increase graft immunogenicity and reduce

3. Detection of p53 in inflammatory tissue and lymphocytes using immunohistology and flow cytometry: a critical comment.
AIMS: To analyse the expression of p53 in lymphatic cells found in inflammatory tissues and the peripheral blood by immunological methods. METHODS: Immunohistological analysis of synovial tissues from patients with rheumatoid arthritis and flow cytometric analysis of peripheral blood lymphocytes were performed with anti-p53 antibodies from different sources.

6. Demonstration of oestrogen receptors in paraffin wax sections of breast carcinoma using the monoclonal antibody 1D5 and microwave oven processing.
This study aimed at assessing the usefulness of a new monoclonal antibody (1D5) for the demonstration of oestrogen receptors (ER) in paraffin wax sections, using brief microwave processing rather than proteolytic predigestion. Routinely processed paraffin wax sections of 50 cases of breast carcinoma with known ER concentrations, estimated by the standard dex

7. Patterns of chronic liver disease in Kuwait with special reference to localisation of hepatitis B surface antigen.
Two hundred and fifty six consecutive liver biopsy specimens (without secondary malignancy) collected over five years were reviewed to characterise the pattern of liver diseases encountered in the Kuwait region. A relatively high proportion of chronic active hepatitis (19%) and cirrhosis (40%) was found. Localisation of HBsAg was carried out by the histochem

8. Lesions of primary and secondary syphilis contain activated cytolytic T cells.
This study demonstrates that CD8+ cytotoxic lymphocytes (CTL) are found in both primary and secondary syphilis lesions. CD8+ T cells were detected by immunohistology, and mRNAs for granzyme B and perforin were detected by reverse transcription and PCR, suggesting that CD8+ cytotoxic lymphocytes are activated.

9. Multiblock slides: a useful technique for teaching.
Data on the quality of a modified method for producing multiblocks from conventional blocks of paraffin wax embedded histological material are reported. Originally devised as a way of assessing antibodies for immunohistology, the technique is particularly suited to producing a set of reference and teaching material for use by trainee and senior pathologists.

10. Role of Actin Filament Network in Burkholderia multivorans Invasion in Well-Differentiated Human Airway Epithelia
The role of the actin-based cytoskeleton in the internalization process of Burkholderia multivorans by well-differentiated human airway epithelia was investigated by immunohistology and confocal microscopy. Our data suggest that an intact actin cytoskeleton is required for biofilm formation but not single cell entry or paracytosis.

11. Staphylococcal toxins and sudden infant death syndrome.
AIMS: To investigate the hypothesis that commonly occurring bacterial toxins cause sudden infant death syndrome (SIDS) by (1), determining in which tissues bacterial toxins are concentrated after intravenous injection in rats; and (2), seeing if the same tissues contain detectable toxins in cases of SIDS. METHODS: The tissue distribution of intravenously inj

12. Intraocular lymphoma: immunological and cytological analysis.
We retrospectively reviewed the cytology and immunohistology of vitreous specimens from nine patients with intraocular lymphoma (ocular reticulum cell sarcoma). A single vitreous biopsy specimen was not always adequate to establish the diagnosis in this condition. Cytological evaluation was more accurate than lymphocyte surface marker analysis to differentia
