13. Polpação de palha de milho, utilizando-se diferentes processos organosolv
Taking into account the availability of corn husks and the increasing interest for alternative raw materiais that can replace wood in the manufacture of paper, we have investigated the possibility of pulping corn husks using different Organosolv processes. Chemical analysis gave the following results: 13% humidity, 1% ash, 7% extractives, 24% Klason lignin,

14. Regiões organizadoras do nucleolo (NORs) em celulas mesoteliais e carcinomatos as de liquidos caritarios : auxilio no diagnostico diferencial de exames citologicos
The AgNOR reaction was performed on effusions and peritoneal washings, and the silver dots counted on normal or reactive mesothelial cells versus carcinomatous cells, ascertained by previsous HE staining. The mean values were 1.71 for the former (n=49) and 3.98 for the latter (n=25). The intersection between the two group distributions was 2,66, leaving a ch

15. Residuos de agrotoxicos em morangos e sua redução por lavagem com agua e estocagem em geladeira (5o.C)
According to good agri cultural pract ice (GAP), the pesticides captan, dicofol and mancozeb were applied in strawberries cultivated in experimental fields in simple and double doses. At 0, 1, 4, 7, 14 and 21 day post-harvest intervals the residues of these pesticides were determined after the fruits were washed in running tap water for 1 minute and after st

16. Value of washings and brushings at fibreoptic bronchoscopy in the diagnosis of lung cancer.
A retrospective study was performed to evaluate the diagnostic yield for lung cancer from histological biopsy specimens and from washings and brushings for cytological examination taken at fibreoptic bronchoscopy. The records of 680 bronchoscopies were analysed. Of 300 patients eventually diagnosed as having a malignant lesion, 188 had had biopsy, washing, a

17. Influence of the Natural Microbial Flora on the Acid Tolerance Response of Listeria monocytogenes in a Model System of Fresh Meat Decontamination Fluids
Depending on its composition and metabolic activity, the natural flora that may be established in a meat plant environment can affect the survival, growth, and acid tolerance response (ATR) of bacterial pathogens present in the same niche. To investigate this hypothesis, changes in populations and ATR of inoculated (105 CFU/ml) Listeria monocytogenes were ev

18. Fluorimetric and microbiological assays of erythromycin concentrations in plasma and vaginal washings.
Using a microbiological and a fluorimetric assay to determine penetration of erythromycin into vaginal fluids, concentrations were measured in plasma from nine men one hour after a single oral dose of erythromycin stearate 2 g and in vaginal washings and plasma samples taken simultaneously from 11 women two hours after the last dose of a 10-day course of ery

19. IgA and IgG anti-ragweed antibodies in nasal secretions. Quantitative measurements of antibodies and correlation with inhibition of histamine release.
Total secretory IgA and specific anti-antigen E (AgE) antibodies (ab) in the IgA and IgG classes were measured in concentrated nasal washings from ragweed allergic and normal individuals by antigen binding or anti-alpha-radioimmunoassays. Virtually all the allergic patients had significant IgA (45/49) and IgG (46/49) ab to AgE in their nasal washings. By con

20. Activation of Alveolar Macrophages Exposed to Lavage-Procured Immunoglobulin G Obtained from Normal Rabbit Lungs
Pulmonary washings from rabbits were freed of cells and added to the monolayers of homologous alveolar macrophages (AM). At 1 h after incubation with the pulmonary washings, many more cells adhered to glass, spread out, and showed enhanced Nitro Blue Tetrazolium reduction. The maximal effect of the pulmonary washings on AM activation was obtained 12 h after

21. AEROBIC AND ANAEROBIC BACTERIAL COUNTS OF NASAL WASHINGS: PRESENCE OF ORGANISMS RESEMBLING CORYNEBACTERIUM ACNES
Watson, Elinor D. (Washington University, St. Louis, Mo.), Nanci J. Hoffman, Richard W. Simmers, and Theodor Rosebury. Aerobic and anaerobic bacterial counts of nasal washings: Presence of organisms resembling Corynebacterium acnes. J. Bacteriol. 83:144–148. 1962.—Aerobic and anaerobic colony counts in blood agar were made of 40 samples of nasal washings

22. Superoxide production in pulmonary alveolar macrophages and killing of BCG by the superoxide-generating system with or without catalase.
The superoxide production of BCG-infected and noninfected alveolar macrophages was measured by superoxide dismutase-inhibitable nitro blue tetrazolium reduction. The cells were incubated with or without cell-free bronchial lavage fluid (pulmonary washings). When control alveolar macrophages were infected by BCG, superoxide production was decreased markedly,

23. Responses of mice immunized with influenza virus by serosol and parenteral routes.
Antibody levels in sera and respiratory secretions and resistance to respiratory infections were examined in mice given live infuenza virus in small-particle (2 mum) aerosols, large-particle (10 mum) aerosols, intraperitoneally, and subcutaneously. After parenteral administration antibody was found primarily in the serum, but small amounts were recovered in

24. Rapid detection of respiratory syncytial virus in nasopharyngeal secretions by enzyme-linked immunosorbent assay.
A new enzyme-linked immunosorbent assay (ELISA) respiratory syncytial virus antigen detection kit (Ortho Diagnostics, Inc., Raritan, N.J.) was compared with virus culture and with the indirect fluorescent antibody test (FAT) by using fresh nasal washings from children with suspected respiratory syncytial virus infection. Both uncentrifuged nasal washings and
