    Notes: Summary The chimney sweep is professionally exposed to air pollution and carcinogenetic substances more than others. Within the scope of an occupational-medicine study begun in 1974, 121 chimney sweeps were examined with regard to history, physical status, pulmonary function including X-rays. The concentrations of different noxious substances at the place of work were measured. At the same time they underwent an ENT-medical examination including X-ray studies of the paranasal sinuses. In 1976 the follow-up examination was performed. The larynx and pharynx of all subjects were endoscopically inspected. More than 60% showed an inflammation or irritation of the pharyngeal and laryngeal mucosa. In24 of the pathological X-ray findings in the paranasal sinuses mostly cysts, solitary or multiple, were found by endoscopic inspection. This follow-up examination contributes to the evaluation of the etiological role of chronic inflammatory diseases of the upper respiratory mucosa in chronic bronchitis.

    Notes: Summary Endoscopic methods as the zoom-epipharyngoscopy and the transnasal inspection of the epipharynx enable an exact examination and diagnosis in the organic or functional lesions of the pharyngeal tube. The physiological and pathological movements of the tubal torus, the pharyngeal tubal orifice and the soft palate are demonstrated.

    Description / Table of Contents: Summary It is the task of each medical specialty to develop guidelines for diagnosis and therapies. Examinations done by several specialties should follow a common consensus. A randomized survey at 70 German ENT departments investigated the current position of tracheobronchoscopy and esophagoscopy at each institution. Sixty questionnaires were evaluable. Altogether 8,295 tracheobronchoscopies and 10,404 esophagoscopies were performed. Thirty-six percent of all tracheobronchoscopies and 6% of all esophagoscopies were done with a flexible system. Approximately 58% of all tracheobronchoscopies and 55% of all esophagoscopies were performed for tumor staging. Complications during tracheobronchoscopy occurred in 0.8% of cases and in 0.58% of the esophagoscopies. Using these data an interdisciplinary quality assurance concept was developed for tracheobronchoscopy and esophagoscopy. Current experience has shown that a otolaryngologists in Germany mainly perform rigid tracheobronchoscopy and esophagoscopy. Although endoscopy is mostly done in cases with varied anatomic structures, complications are very rare and comparable to flexible techniques. Greater experience with flexible systems also is to be encouraged in ENT departments.
    Notes: Zusammenfassung Hintergrund: Es muß Aufgabe jedes einzelnen Fachbereichs sein, Leitlinien für die von ihm behandelten Erkrankungen und durchgeführten Untersuchungen zu erstellen. Für fachübergreifende Behandlungen ergibt sich die Forderung nach einem gemeinsamen Konsens. Material und Methoden: Durch eine anonymisierte Umfrage an 70 HNO-Kliniken und Belegabteilungen sollte ein Ist-Stand der Tracheobronchoskopie und Ösophagoskopie in der Hals-Nasen-Ohren-Heilkunde erhoben werden. Ausgewertet werden konnten insgesamt 60 Fragebögen. Unter Berücksichtigung dieser Ergebnisse wurde ein Leitlinienentwurf „Tracheobronchoskopie und Ösophagoskopie” erarbeitet. Ergebnisse: Insgesamt wurden 8295 Tracheobronchoskopien und 10404 Ösophagoskopien durchgeführt; 36% der Tracheobronchoskopien und 6% der Ösophagoskopien erfolgten mit einem flexiblen System. In 58% der Fälle erfolgte die Tracheobronchoskopie zum Tumorstaging, bei der Ösophagoskopie betrug die Anzahl der Untersuchungen zum Tumorstaging 55%. Die Komplikationsrate bei der Tracheobronchoskopie betrug 0,8%, bei der Ösophagoskopie 0,58%. Aufbauend auf diesen Strukturdaten wurde ein interdisziplinär erarbeiteter Leitlinienentwurf in einem Delphiverfahren abgeglichen. Schlußfolgerungen: Die Hals-Nasen-Ohren-Ärzte in Deutschland führen mehrheitlich die starre Tracheobronchoskopie und Ösophagoskopie durch. Obwohl größtenteils bei veränderten anatomischen Strukturen endoskopiert wird, geschieht dies mit Komplikationsraten, die vergleichbar sind mit internationalen Studien bei Einsatz flexibler Systeme. Trotzdem sollte sich der HNO-Arzt vermehrt auch um die flexiblen Techniken bemühen.

    Notes: Abstract Endo-mannanases and endo-xylanases cleave different heteromannans and xylans yielding mainly dimers and trimers of the corresponding sugars as end-products. However, in the early stages of hydrolysis, four purified mannanases and four xylanases from fungal and bacterial origin, examined in this study, showed a different pattern of released oligomers (determined up to the pentamers). Furthermore, some of these enzymes showed a preference for cleaving the polysaccharides in the middle of the chain while others acted more at the end. When the increase in the specific fluidity of mannan and xylan solutions per reducing sugar released (K v) was measured against the bleaching effect of the enzymes on softwood kraft pulp, a correlation was found. A xylanase from Penicillium simplicissimum (K v = 0.15 l mPa−1s−1g−1) and a mannanase from Sclerotium rolfsii (K v = 0.12 l mPa−1s−1g−1) applied in a O(QX)P bleaching sequence (O = oxygen delignification, X = treatment with hemicellulolytic enzymes, Q = chelation of metals, P = treatment with hydrogen peroxide in alkaline solution) gave a high brightness increase of 3.0% and 1.9% ISO respectively. A less significant brightness increase was obtained with enzymes showing lower K v values, such as a xylanase from Schizophyllum commune (Kv = 0.051  l mPa−1s−1g−1, 0.2% ISO) and a bacterial mannanase (K v = 0.061 l mPa−1s−1g−1,0.5% ISO).

    Notes: Summary The kinetic behavior of heterogenous microbial populations in biotechnological processes can be described with the aid of the Monod equation extended by a term kd for endogenous metabolism. The modified Monod equation is examined in detail to demonstrate the influence of the kd-term on the values of the Monod parameters μm and KS. The principles of kinetic analysis are also shortly considered in connection with fermenter design. The prerequisites for kinetic analysis together with parameter determination are demonstrated.

    Notes: Abstract  The contamination of cereals with field-growing Fusarium species can be a health hazard since Fusarium are known for their ability to produce mycotoxins like zearalenone (ZON) and deoxynivalenol (DON). For this study the formation of ZON was investigated under controlled growth conditions. Ergosterol, as an indicator of fungal growth, and ZON were analysed by HPLC with UV and fluorescence detection respectively. It is shown that ZON is synthesised in the late growth phase of the fungi, which is typical for secondary metabolites. Milling of contaminated wheat shows a reduced content of ZON in fractions of low ash content. Consequently the concentration of ZON in bran, which has a high ash content, was much higher.
