    Notizen: Summary A mouse model of cutaneous candidiasis was used to determine if the prominent neutrophilic infiltrates in the infected skin of nonimmune animals were responsible for inducing the early phase of epidermal proliferation seen in these infections. Both the organisms and resulting neutrophilic microabscesses were found in the cellular layers of the epidermis at 12 h after inoculation, and were then extruded together to a more superficial site in the stratum corneum over the next 1–2 days. The degree of epidermal proliferation elicited at the site of the Candida foci, as determined from the thickness of the cellular layers of the epidermis, was the same for foci with neutrophils as for those without, even when the latter came from severely leukopenic animals. The location of neutrophils within the infected skin or the numbers of organisms present did not seem to make a difference with respect to the degree of epidermal proliferation produced at the site of Candida foci. These data suggest that in acute experimental cutaneous Candida infections the organisms can elicit a vigorous epidermal proliferative response in the absence of the neutrophilic infiltrates usually seen in these infections.

    Notizen: Abstract Although there are several symptomclassification systems for irritable bowel syndrome(IBS), for example, the Manning or Rome criteria, therehas been no previous research on how well theseclassifications correspond to each other or to personsdiagnosed with IBS. We examined data from the DigestiveDisorders Supplement of the 1989 National HealthInterview Survey (NHIS) to assess demographic,socioeconomic, and health status characteristics of two groupsof IBS sufferers — those who met the Manning orRome criteria and those who reported having IBS but didnot meet either criteria. The results showed that the overlap between estimates of IBS and personswith IBS-like symptoms depended on the definition ofIBS. There were socioeconomic differences between thetwo IBS groups and higher rates of functional orwork-related activity limitation and health care utilizationfor all IBS groups relative to US national averages. Insummary, these findings indicate that IBS affects alarge portion of the US population, regardless of the definition used to describe thecondition. Our results suggest that there is a largeundiagnosed population with numerous symptoms consistentwith IBS, but further research is required to determine the differences between people who do and donot seek care, their impact on the health care system,and future therapies to reduce symptomatology andsuffering.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Für ein Seitenkettenpolymeres, das zusätzlich zum teilkristallinen Zustand und zur isotropen Schmelze einen flüssig-kristallinen Zustand aufweist, wurden die Strukturen und Texturen untersucht sowie thermodynamische Eigenschaften. Außerdem wurde die Kinetik der Phasenumwandlungen analysiert. Es zeigt sich, daß die Eigenschaften zwischen denen üblicher Polymerer und denen von niedrigmolekularen flüssigen Kristallen liegen. Insbesondere zeigte sich, daß die Beziehung zwischen molekularer Struktur und Textur von der bei niedrigmolekularen flüssigen Kristallen abweicht, und daß die Taktizität der Kette einen starken Einfluß auf die Eigenschaften nicht nur der kristallinen Phase sondern auch der flüssig-kristallinen Phase ausübt.
    Notizen: Summary The structures, textures as well as thermodynamic properties of a side chain polymer exhibiting a liquid crystalline phase in addition to a partially crystalline state and the isotropic fluid state were investigated. Furthermore the kinetics of phase transitions between these states were analyzed. It was found that the properties of this polymer are intermediate between that of low molecular weight liquid crystals and common polymers. In particular it was observed that the relation between the liquid crystalline texture and the structure is different from that of low molecular weight liquid crystals and that the properties of the crystalline and liquid crystalline state depend strongly on the tacticity of the polymer.
