[Surgical problems of homeless people].

Unlabelled: Estimated quantity of homeless people in Poland is about 30.000. Health conditions of homeless depends on poor living conditions, alcohol abuse and lack of medical care.

[Mounier-Kuhn syndrome (tracheobronchomegaly)].

The case presents a 43 years old man, cigarette smoker, exposed to wood dust at work, with chronic, ineffective cough symptoms, limited physical exertion and recurring respiratory system infection. Disorders appeared at the age of 33 after severe double-sided pneumonia. Despite the lack of active clinical infection the following microorganisms: Pseudomonas aeruginosa and Staphylococcus aureus MSSA were isolated from patient bronchi mucus.

[Principles of optimal preparation of material from bronchoalveolar lavage (BAL)for cytoimmunologic examinations in interstitial lung diseases ].

In this paper we considered the value of correctly performed bronchoalveolar lavage (BAL) in diagnosis of interstitial lung diseases and in assessment of the activity of pathological process. We indicated the conditions of exact interpretation of the results of BAL cytoimmunological examination, i.e.

Inhibition of erythrocyte aldehyde dehydrogenase activity and elimination kinetics of diethyldithiocarbamic acid methyl ester and its monothio analogue after administration of single and repeated doses of disulfiram to man.

The elimination kinetics of the methyl esters of diethyldithiocarbamic acid (Me-DDC) and its monothio analogue (Me-DTC) has been compared in ten alcoholic patients after a single oral dose of 400 mg disulfiram (Antabuse). Erythrocyte aldehyde dehydrogenase (ALDH) activity was continuously followed in the subjects until complete inactivation. The relation between individual steady-state concentrations of Me-DTC in plasma, blood acetaldehyde concentration and the dose of disulfiram sufficient to give the disulfiram alcohol reaction was investigated in 12 healthy volunteers treated with increasing doses of disulfiram and then challenged with ethanol.

Effect of temperature, duration of incubation, and pH of enrichment culture on the recovery of Campylobacter jejuni from eviscerated market chickens.

To establish an enrichment system of high efficiency for recovery of Campylobacter jejuni from market chickens, the effects of the temperature, duration of incubation, and pH of the enrichment culture on the isolation of the bacterium were evaluated. Whole chickens or chicken parts in plastic bags were individually rinsed, and the washings filtered through cheesecloth. The cells were separated from the washings by centrifugation, and the pellet was inoculated into 100 mL of enrichment broth.

A survey of microorganisms for thermonuclease production.

A total of 1204 cultures comprising 16 genera were surveyed for production of thermonuclease (TNase) in milk. Cultures other than Staphylococcus capable of TNase production were restricted to two genera, Streptococcus and Bacillus. Nineteen percent of 338 group D streptococci comprising four species (85% of which were Streptococcus faecalis) and 17% of 60 streptococci belonging to other groups produced TNase.

Inhibitory effect of cocoa powder on the growth of a variety of bacteria in different media.

The inhibitory effect of cocoa powder on 102 organisms belonging to 13 genera was determined. All organisms tested were inhibited by 5% cocoa. Shigella, Staphylococcus, Micrococcus, and Bacillus were the most sensitive.

Improved procedure of selective enrichment of Shigella in the presence of Escherichia coli by use of 4-chloro-2-cyclopentylphenyl beta-D-galactopyranoside.

A previously described procedure for the selective enrichmen of Shigella in competition with E. coli has been modified and tested with a total of 48 strains of the four Shigella species. The new enrichment medium consists of 1,5-strength trypticase soy broth, 1 mM 4-chloro-2-cyclopentylphenyl beta-D-galactopyranoside (CPPG), 0.

Preenrichment procedure for detection of Salmonella in gelatin.

Trypticase soy broth was superior to nutrient and lactose broths as a preenrichment medium for the detection of Salmonella in artificially and naturally contaiminated gelatin. The detection rate for Salmonella were further enhanced when homogenization of the gelatin-broth mixture was accomplished by the use of gelatinase rather than by heating of 45 degrees C. Detection rats were also increased by adjusting the pH of the gelatin-broth mixture of 7.

Selective enrichment of Shigella in the presence of Escherichia coli by use of 4-chloro-2-cyclopentylphenyl beta-D-galactopyranoside.

A procedure involving the use of citrate-buffered lactose broth (pH 6.5) containing an analogue of a beta-galactoside (4-chloro-2-cyclopentylphenyl beta-D-galactopyranoside) has been developed for the enrichment of Shigella in competition with a 100-fold higher population of Escherichia coli. The system makes use of the beta-galactosidase activity of E.
