Consistent with the occurrence of active Lassa fever cases, the prevalent Lassa virus activity seems to be in Lofa County and neighbouring Guinea. Statistically, medical personnel exposed to Lassa fever patients are not at a higher risk for Lassa virus infection than the general population. The higher level of contact with active cases incurred by the medical profession may be compensated by the usually higher standards of hygiene in the dwellings of such personnel and a concomitant lowered exposure to the natural host (Mastomys natalensis). Convincing conclusions concerning the endemic areas of the three viruses studied were complicated by the movements of the tested persons within Liberia and neighbouring Guinea. However, the fact that Lassa, Ebola and Marburg virus antibodies never appeared in the same serum sample leads one to theorize that the endemic regions of the three viruses are well-separated from each other. Consistent with this finding is the statistically significant different distribution of Lassa and Ebola virus antibody carriers, at least between Lofa County and Bong County. The broad age distribution of persons tested and the wide range of antibody titres observed for the activity of the three viruses suggest that the respective diseases probably occur more frequently in single cases rather than in occasional nosocomial or local epidemics. Considering that active cases of Ebola or Marburg virus disease have never been reported from Liberia, the occurrence of these specific antibodies was surprising. The results seem to indicate that Liberia has to be included in the Ebola and Marburg virus endemic zone. Therefore, the medical personnel in Liberian health centres should be aware of the possibility that they may come across active cases and thus be prepared to avoid nosocomial epidemics. Recent investigations doubt the specificity of the indirect immunofluorescence antibody test concerning Ebola and Marburg viruses (K.M. Johnson, personal communication). Thus the significance of the antibodies to Ebola and Marburg viruses identified in Liberia requires further evaluation.

A traditional beverage in Venezuela, "Chicha de Arroz" (Rice Chicha), was chosen. The various formulas studied were based on rice, non-fat milk and different kinds of soy flour, in addition to sugar, vegetable oil, vitamins, ferrous sulfate and different flavors. A product with protein and caloric values similar to those of milk was obtained. Twenty formulas were prepared and submitted to physico-chemical, microbiological and sensorial evaluations with respect to flavor, color, viscosity and stability during period of refrigeration. The most adequate formula was prepared on a pilot-plant scale. Rat assays gave the same PER results as those of casein. Consumer acceptability was tested on 1,080 school children, and showed to be greater than 95%. The stability was superior to that of milk and the cost, approximately three-fourths that of the latter. In the school-snack program of the National Institute of Nutrition, milk is now being replaced by this Chicha.

Mixed solutions of the two elements, In and Dy, were continuously introduced into the stream water as non-radioactive tracers for 1.8 hr and 2.1 hr in two separate experiments. In the first experiment, the two elements were added in a non-chelated form; in the second expreiment, upstream from the first, indium-DTPA [(carboxymethylimino)bis(ethylene-dinitrilo) tetraacetic acid pentasodium salt] and dysprosium-DTPA were used as tracers. Instrumental neutron activation analysis was used to determine the quantity of each stable tracer sorbed to the alder roots and the amount remaining in the stream water. Non-chelated In was sorbed by roots up to a concentration of 1.7 Î¼g In/g of root (dry wt), whereas the In-DTPA sorption rate was higher by a factor of approximately 2. Non-chelated Dy was sorbed by roots up to a concentration of 29 Î¼g Dy/g of root (dry wt), while the sorption of Dy-DTPA was less by a factor of 8.

Pub Date Free Form 1981/ Volume 1 Issue 9 Start Page 464 Other Pages 467 Notes Place of Publication ISSN/ISBN 0025-729X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Employees from two non-asbestos industries were examined to assess the prevalence of asbestos-related lung disease. Of the 214 employees, one suffered from a malignant mesothelioma of the pleura and in 13 (6.1%), pleural plaques were diagnosed radiologically. The plaques were symptomless and not associated with any disturbance in respiratory function. The sole source of asbestos fibre in one factory was the asbestos insulation surrounding steam and hot water pipes similar to that found throughout industry. Exposure occurred as the result of the way in which this insulation has been handled routinely in industry by people who have commonly been unaware either of their exposure or of its significance. In the second factory there was the possibility of additional exposure originating from a neighbouring industry that was a major consumer of asbestos. The results suggest that maintenance workers may be particularly at risk and that the presence of pleural plaques may be under-reported in the absence of a history of asbestos exposure to direct attention towards them. The presence of pleural plaques has important consequences for the individual and for others who have shared the work environment.

Such a group constitutes a very homogeneous sample for dietary habits and underwater activity, handed down from father to son. Some of these sponge-divers dive while holding their breath; others use 'narghile', a special apparatus consisting in a nosepiece connected to an air compressor placed in the boat. As their activity is continuous and prolonged for several months in the years with repeated dives from dawn to dusk and, because air output of narghile is nearly constant, it is possible to deduce that in these subjects functional respiratory modifications occur. In evaluating three groups (skindivers, narghile-divers and control-group) no particular changes of static and dynamic pulmonary volumes were noted. Only Expiratory Reserve Volume is higher in spite to Knudson's values; this is probably due to psychological and emotional factors.

Pub Date Free Form 1980/ Volume 13 Issue 4 Start Page 425 Other Pages 437 Notes Place of Publication ISSN/ISBN 0049-6979 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Two important environmental parameters could be identified as being the main causes of pipe-borne water contamination in the City of Benin. These are combined effects of rainfall and excessive construction work and, secondly, the lack or inadequacy of plumbing codes. To study the combined effects of rainfall and excessive construction on the contamination of water, samples were tested for total coliform using the multiple-tube fermentation test. Sites were chosen to allow for the comparison of the coliform counts in areas of comparatively insignificant construction to areas of excessive public construction. Results show that in the areas of heavy public construction, the curves for both the rainfall and the coliform counts in the consumer lines were skewed in the same manner. The peak rainfall was in September (437.1 mm), which corresponds to peak coliform number in the consumer lines for both Zone A (62 coliforms/100 ml) and Zone B (60 coliforms/100 ml) for the same month. When compared to the area of insignificant public construction as shown in Zone C, rainfall had little or no effect on the coliform counts either at the pumping station or in the consumer line. The maximum number of coliforms recorded for the consumer line was 5/100 ml during the month of June. Results suggest that the high counts of coliforms in the Benin City water supply could be attributed primarily to the effects of construction which resulted in pipe breakage. During heavy rainfall and flooding, water under flood pressure enters the pipes through cracks, improperly tightened joints and damaged pipes. The improper enforcement of plumbing codes or lack of such codes was also identified as another cause of the water contamination as shown in Zone D. A study of the effects of water pipes passing through septic tank drain fields also shows that such effluents served as another source of major contamination. The highest recorded number for coliforms for the pipe-borne water just before entering the septic tank drain field was 12/100 ml, and after it passed through the field the number had gone up to 60/100 ml. Artificial contamination of the septic tank effluents to try to detect leaks in the water pipes passing through the absorption field was investigated. The bacterial contaminant could be recovered in the pipe-borne water and the quantity was skewed in the same manner as total rainfall between periods of sampling.
