    Notizen: The enzymatic hydrolysis of lactose has been studied using β-galactosidase (Aspergillus niger) immobilized on collagen. The immobilization process employs simple and inexpensive techniques to bind the enzyme to collagen through noncovalent bond formation. The stability and reusability of collagen bound lactase membranes was evaluated in a biocatalytic modular reactor. Little or no loss in reactor activity was observed after storage for a period of 90 days. Following an initial decrease in activity, stable limit activity was maintained over a number of reactor volume replacements. The activity of the fungal lactase in both the soluble and bound states was determined in ultrafiltered acid whey. The catalytic potency of the enzyme, in both states, showed inhibited enzyme activity in acid whey, as compared to aqueous lactose. In the bound state, the enzyme experienced a partial irreversible inhibition.

    Notizen: [Auszug] On the basis of these theoretical considerations, the following method was developed: (1) The acidity of the milk under investigation is determined in Soxhlet-Henkel degrees. This is the titre of N14 sodium hydroxide with 100 ml. of milk, using 2 ml. of a 2 per cent alcoholic solution of ...

    Notizen: Zusammenfassung Die Gleichrichtermethode wird prinzipiell zur Messung der Maximalwerte der Spannungskurven, die blo\ zwei Scheitelwerte in einer Periode aufweisen, angewendet. Die Spannungskurven, die dieser Bedingung nicht entsprechen, kommen aber in der Praxis manchmal vor. In diesem Falle wird die Messung der Scheitelspannung mit einem Fehler belastet. Eine praktische Methode der Bestimmung dieses Fehlers existiert unseres Wissens noch nicht. Die anderen hier vorkommenden Fehler, die ihre Ursache in der Unvollkommenheit der Anordnung der Elemente haben, können nach dem Verfahren von H. König bestimmt werden, das jedoch keinen allgemeinen Charakter hat und ziemlich umstÄndlich ist. Es ist besser die obere Grenze des dabei begangenen Fehlers auf die hier nÄher beschriebene einfache Weise zu bestimmen. Au\erdem kann die Messung mit anderen Fehlern belastet werden, deren Ursache in der mangelhaften Ausführung der Me\anordnung liegt (schlechte Kontakte, Sprühen der Zuleitung usw.). Solche Fehlerquellen sollen sorgfÄltig geprüft und beseitigt werden. Bei der kapazitiven Spannungsmessung empfiehlt es sich, die dunkelglühenden Elektronenröhren als Gleichrichter zu verwenden. Man kann dann eine Zusatzbatterie vermeiden, die sonst zur Trennung der Arbeit der Gleichrichter nötig ist. Unter diesen Bedingungen kann die Gleichrichtermethode der Messung der Scheitelwerte der Hochspannung als eine sehr praktische und genaue Me\methode, auch in Fabriklaboratorien, betrachtet werden.

    Notizen: Summary The authors analysed a series of 111 adult patients admitted to the Department of Neurosurgery, Medical University of Łódź directly after trauma with initial GCS of 3 points. 74% of them had intracranial haematoma, mainly subdural, and were treated surgically within the first 3 hours after trauma. 8 patients had no abnormalities on CT scans. 99 (89%) patients died 2 to 30 days after injury, 8 (7%) survived in a vegetative state, and only in 4 (4%) was a satisfactory result noted, but 2 of them had a stable neurological deficit. 3 of these 4 patients had epidural haematomas and 1 had not abnormalities on repeated CT examinations. We conclude, that among patients with GCS of 3 on admission, only those without major CT abnormalities or with epidural haematoma have a chance of survival. Cases with cerebral leasions on the initial CT examination have an invariably bad prognosis. They could be taken into account as a potential organ donor from the very moment of admission, but only after cerebral circulatory arrest occured and brain death has been proved according to internationally accepted standarts.

    Notizen: Summary This report is based on the authors' personal experience of fifty three studies using Conray 60. The diagnostic role of water-miscible contrast media for ventriculography in neurosurgical patients is discussed. Conray studies of lesions involving the various parts of the ventricular system are illustrated. The possible complications are assessed in relation to the value of the investigation.

    Notizen: Summary Subarachnoid haemorrhage was produced in 26 dogs by injecting fresh homogenous blood into the cysterna chiasmatica. Two types of vasospasm were observed, firstly segmental arterial spasm closely related to the bleeding point and secondly generalized arterial vasospasm not directly related to the bleeding point and often occurring some way from the bleeding point. Reduction in CBF occurred in 61% of cases and was always accompanied by radiological vasospasm. However, in about one quarter of the cases with vasospasm there was no alteration in CBF.

    Notizen: Summary Insulin neuritis, or painful neuropathy following rapid improvement in glycaemic control, is well recognised but its aetiology is unclear. An understanding of the processes involved in the genesis of acute painful neuropathy of rapid glycaemic control may give an insight into the early pathogenetic factors leading to diabetic nerve damage in general. We have identified five subjects with insulin neuritis including one who developed severe autonomic neuropathy following treatment with insulin. Subjects underwent: 1) assessment of neuropathic symptom and deficit scores; 2) quantitative sensory and electrophysiological studies and 3) sural nerve epineurial vessel photography and fluorescein angiography in vivo. The sural nerve photographs were independently graded by an ophthalmologist. All subjects with insulin neuritis presented with severe sensory symptoms but clinical examination and electrophysiological tests were normal except in the subject with the severe autonomic neuropathy in whom all the tests were abnormal. On nerve photography, there was an abundance of epineurial nutrient vessels although these showed severe abnormalities including arteriolar attenuation, tortuosity and arterio-venous shunting in all subjects. Proliferating neural ’new vessels' which bear striking similarities to those found in the retina and that were more leaky to fluorescein than normal vessels, were observed in three subjects. Venous distension and/or tortuosity was also observed in three subjects and this was most marked in the subject with severe autonomic neuropathy. This study shows that epineurial nutrient vessel anatomy is abnormal in subjects with acute painful neuropathy of rapid glycaemic control, a condition previously thought to be purely metabolic in origin. The presence of epineurial arterio-venous shunting and a fine network of vessels resembling the new vessels of the retina, may lead to a ’steal' effect rendering the endoneurium ischaemic. This process may be important in the genesis of neuropathic pain, and further supports the importance of vascular factors in the pathogenesis of diabetic neuropathy. [Diabetologia (1996) 39: 329–335]

    Notizen: Summary 136 patients older than 70 years, admitted to our neurosurgical ward directly after head trauma, were analysed. 40% of them were admitted with low GCS, below 9 points, and showed a mortality of 85%. 45 patients had intracranial mass lesions — the commonest was subdural haematoma, with a low incidence of epidural haematomas. In patients admitted with GCS above 12, mortality was 20%, mainly due to pneumonia. Satisfactory results were achieved in 30% of trauma victims. From patients with intracranial space occupying lesions and GCS below 9 points on admission practically all died, despite aggresive surgical treatment and intensive care. Thus, especially in departments with limited resources, therapy can be limited, or even no therapy may be introduced in this group. Surgical treatment can be limited only to patients who are conscious on admission. In patients with non-surgical lesions, low GCS — below 9 points — leads to mortality of 80%, and in this group we propose aggresive intensive care for 24 hours and the limitation of further “maximal” therapy only to those, who significantly improve within this period of time. If the patient has a non-surgical lesion and is conscious after trauma, aggresive treatment of extracranial complication is the most important, because brain injury can usually be well tolerated by these patients. If pneumonia or heart complications do not occur this group of old patients often have a good prognosis.
