Isolation and characterization of Pediococcus halophilus from salted anchovies (Engraulis anchoita).

The presence of bacteria in salted anchovies during and at the end of the curing process was investigated. Attempts to isolate bacteria under aerobic or anaerobic conditions led to the isolation of only bacteria of the genus Pediococcus which were identified as Pediococcus halophilus. The isolates correspond to a rather heterogeneous group in which some of the members differ in some biochemical tests from the types described in the literature.

Cryoglobulinemia and fibronectin.

Isolated and washed cryoglobulins obtained from 30 patients with different diseases were studied for the presence of fibronectin by immunoelectrophoresis. Two of the isolated cryoglobulins were of the type I, 3 were of the type II, while the other 25 were of type III. Despite extensive washing, fibronectin was detected in all the cryoprecipitates. Our results indicate the constant presence of fibronectin in the cryoprecipitates from patients with different diseases and types of cryoglobulin. The possible mechanisms by which fibronectin could act in the precipitation of immunoglobulins are discussed.

Spontaneous regression of bilateral hilar lymphadenopathy in renal cell carcinoma.

A 26-year-old woman presented with a spontaneous regression of bilateral hilar lymphadenopathy, simulating the natural course of acute sarcoidosis. Several months later the lymph nodes reappeared and finally a metastatic renal cell carcinoma was found. The need for histological confirmation in the diagnosis of sarcoidosis is discussed.

Central and peripheral actions of alpha-MSH in the thermoregulation of rats.

The effect of alpha-MSH on thermoregulation in rats at room temperature was examined. alpha-MSH (1 microgram ICV or 30 micrograms IP) alone did not alter temperature. However, this peptide was a potent antipyretic when administered centrally or peripherally in rats treated with pyrogen derived from Salmonella typhi.

Prevalence of chronic bronchitis in the children of Lisbon.

Portugal is one of the European countries with the highest mortality from Chronic Bronchitis (CB). This constitutes a severe problem as CB is one of the main causes of absenteeism and incapacity. To determine the prevalence of this disease, an epidemiological study was planned. The first part of this study involved the children of Lisbon because of the large number of children attending chest clinics for respiratory symptoms, because a similar study is being carried out in Europe by WHO in children from 8 to 10 years of age and because of the importance that this type of study in children may have in the prediction of the development of CB in adults. The study consisted in a standard questionnaire (WHO), a physical examination based on the CECA questionnaire, an ENT examination, a simple respiratory function test and a 70 mm microradiograph of the chest. 4148 children of both sexes, whose ages ranged from 6 to 14 were studied. The operational diagnosis of CB was based on the presence of chronic cough for the past 2 years, for at least 3 months and nearly every day during the Autumn and Winter months. The prevalence of CB in the overall population was 4.9%. The global analysis of the data collected seems to show the following: - Measles and whooping cough contribute to the incidence of CB. --Socio-economic conditions probably contribute to the increase in the incidence of CB. --A high incidence of ENT pathology was found in CB. --Atmospheric pollution does not appear to influence the incidence of CB.
