    Notes: [Auszug] Conventional zone plates work by blocking out alternate zones. Constructive interference of the waves diffracted from the remaining zones occurs at specific points which are in an image relationship to their original source. Lord Rayleigh7 pointed out that phase reversing, rather than absorbing ...

    Notes: [Auszug] It is of interest to investigate these metabolic derivatives further by the use of electron-capture gas chromato-graphy, a tool of great sensitivity in the detection and isolation of chlorinated insecticides. Mature male and female Sprague-Dawley rats within a weight range of 250-350 g were fed ...

    Description / Table of Contents: Zusammenfassung Verschiedenen Tieren wurde unter ständiger Kontrolle des Augenhintergrundes Luft in die linke Herzkammer oder in eine Arteria carotis communis injiziert. Unmittelbar nach der Luftinjektion sieht man zahlreiche Luftbläschen in den Arterien der Netz- und Aderhaut strömen. Die blutleeren Gefäßstrecken der Netzhaut treten als silberweiße Perlen bzw. Fäden mit einer scharfen, zum bluthaltigen Teil der Gefäßstrecke konvexen Begrenzung in Erscheinung. Dieser Befund kann tierexperimentell in jedem Fall erzielt werden, wobei die dafür erforderliche Luftmenge erheblich variiert. Die Augenhintergrundsuntersuchung kann für die Diagnosestellung der arteriellen Luftembolie beweisend sein; sie ist jedoch nur in den ersten 20–30, maximal bis 60 min nach dem Ereignis erfolgversprechend. Nach Todeseintritt ist die Luft noch 6–8 h deutlich zu sehen und von postmortalen Frakturierungen der Blutsäule zu unterscheiden. Diese Befunde sind damit auch für die Gerichtsmedizin bedeutungsvoll. Die Ophthalmoskopie dürfte ein neues diagnostisches Hilfsmittel bei der pathologisch-anatomisch sehr schwer beweisbaren zerebralen Luftembolie mit geringer Überlebenszeit darstellen.
    Notes: Summary Air was applicated into the left ventricle or arteria carotis communis under continous control of the fundus oculi. The injection of air is immediately followed by the appearance of numerous silver-white small sized air bubbles and/or columns of air with an distinct convex border in the arteries of retina and chorioid. The needed quantities of air varied. After 20 to 30 min on average the vessels were airless again. Extremely the air was seen till 6 to 8 hours after death when the first post mortem fractionations begins. Therefore suggestion can be made ophthalmoscopy could be a possible proof to state arterial air embolism if limited to the first hour after occurrence.

    Description / Table of Contents: Summary Three fatal cases of intoxication by the desinfectant C4 (Alkyl-dimethylbenzylammoniumchloridgemisch) are reported. The unusual mode of administration of the poison render these cases as rare. In two cases the desinfectant was erroneously administered via enema, using a 3 % solution in unknown amounts. In the third case the desinfectant was used in an attempt to secure abortion. Concentration and amount were unknown. In all three cases death occured very rapidly. The findings at autopsy and the result of the chemical-toxicological analyses are reported. Identification of the toxic substances in the abortion cases was possible. The mode of action of C4 is discussed in the light of the available literature.
    Notes: Zusammenfassung Es werden drei tödliche Vergiftungen mit dem Desinfektionsmittel C4 beschrieben. Sie gehören auf Grund der Applikationsart zu den bisher seltenen Fällen. Einer 42jährigen und 43jährigen Frau wurden infolge Verwechselung mit Wofacutanlösung Einläufe mit einer 3 % igen C4-Lösung nicht bekannter Menge verabreicht. — Im dritten Fall handelte es sich um einen Abtreibungsversuch einer 33jährigen Frau mit C4-Lösung. Menge und Konzentration des verwendeten Desinfektionsmittels blieben unbekannt. Der Tod trat in allen Fällen sehr schnell ein. Die Obduktionsergebnisse und das Ergebnis der toxikologisch-chemischen Untersuchungen werden mitgeteilt. Dabei konnte bei einer vaginalen Intoxikation zum ersten Mal der Nachweis der Wirkstoffe auch in den II. Giftwegen geführt werden. Der Wirkungsmechanismus der C4-Intoxikation wird an Hand der vorliegenden Literatur diskutiert.

    Description / Table of Contents: Zusammenfassung Rasche Methoden zur Bestimmung von freiem NPA oder freiem und gebundenem NPA in Blutplasma wurden beschrieben. Nach Eiweißfällung mittels Methanol erhält man relativ gute Absolutwerte nach einfacher Aufarbeitung ohne Derivatisierung. Für eine Einzelbestimmung werden nur 0,25 ml Plasma benötigt. Die Erfassungsgrenze liegt bei 0,4μg NPA/ml Plasma. Das Verfahren ist hinreichend genau.
    Notes: Summary Rapid HPLC methods are described for the determinations of either free N-n-propylnorapomorphine (NPA) or the free and conjugated NPA in blood plasma. The methods employ a methanol protein-precipitation step that produces relatively good absolute recoveries, while permitting a simple work-up procedure without derivatization. Only 0.25 ml of plasma is required for a single determination at a sensitivity limit of 0.4μg NPA/ml plasma. Satisfactory accuracy and precision are achieved with the proposed assay.

    Description / Table of Contents: Zusammenfassung Bei einem Patienten, der mit der peritonealen Dialyse behandelt wurde, heilten die psoriatischen Herde völlig ab. Bei zwei weiteren Patienten waren die Resultate nicht befriedigend. Bei den behandelten und den drei nicht behandelten Patienten war die celluläre Immunität augenscheinlich unterdrückt. Dieses Phänomen ist mit den immunologischen Veränderungen bei Personen mit einer Urämie zu vergleichen. Organische Verbindungen von mittlerem Molekulargewicht, wozu auch die Gruppe der urämischen Toxine gehört, unterdrücken die celluläre Immunität. Deshalb wurden diese Verbindungen bei Psoriatikern untersucht. Der Spiegel der SMMWR war vor jeder Dialyse tiefer als danach, obwohl deren Konzentration während der Dialysebehandlung leicht anstieg. Dies läßt vermuten, daß diese SMMWR-Substanzen in der Epidermis fixiert sind oder im Bereiche der Capillaren vorliegen und dementsprechend während der Dialyse von diesen Orten freigesetzt werden. Die Peritonealdialyse scheint mehr eine wirksamere Behandlungsmethode der Psoriasis zu sein als die Hämodialyse. SMMWR-Substanzen können eine wichtige Rolle in dem Pathomechanismus der multifaktoriellen Erkrankung darstellen.
    Notes: Summary In one patient treated by peritoneal dialysis for psoriasis the skin lesions cleared completely. In two persons hemodialysis gave unsatisfactory results. In treated and another three untreated patients cellular immunity was evidently suppressed. This phenomenon is similar to the immunologic changes in persons with uremia. Solutes in middle molecular weight range (SMMWR) suppress cellular immunity. These compounds were therefore investigated in psoriatics. The level of SMMWR was lower before than after each dialysis, although their concentration increased slightly during the dialytic treatment. This suggests that solutes in middle molecular weight are fixed in the epidermis and/or in the walls of the skin capillaries and that dialysis liberates them from these places. Peritoneal dialysis seems to be a more effective method of treating psoriasis than hemodialysis. Solutes in middle molecular weight range might play an important role in the pathomechanisms of this multifactorial disease.

    Notes: Summary The effect of age on hepatocyte mensuration and mitotic activity 48 h after partial hepatectomy was investigated in rats. Both age and partial hepatectomy had significant effects upon hepatocyte counts per microscopic field. The number of hepatocytes per microscopic field declined with age in the control groups of different advancing ages and in the experimental groups of advancing ages. There was essentially no mitotic activity in the livers of the control groups. However, mitotic counts were greatly increased in livers from those animals that were partially hepatectomized; the increase in mitotic activity in the 13-month-old animals was double over that observed in both the very young and the very old.

    Notes: Summary An analytical method is described which has suitable sensitivity and specificity for analyzing urine samples from workers who are exposed to chlorinated phenols. The phenolic compounds are separated by steam distillation and then extracted into isopropyl ether. Without derivatizing the material, it is analyzed by gas chromatography on a 180 cm x 2 mm i.d. glass column containing 60/80 mesh Tenax GC (ENKA NV, The Netherlands) using flame ionization detectors. The detection limits in urine range from 0.1 mg/l urine for phenol to 1 mg/l for the di- and trichlorophenols. The coefficient of variation for each component is less than 4%. The naturally occurring metabolites cresol and 4-heptanone are also isolated and can be quantified by this method.
