    Notes: Summary Peak serum concentrations are reached after about 2 h following oral administration of 5 mg radioactive glipizide, and in the case of intravenous administration of 1 mg radioactive substance they are reached immediately following the injection. The half-life amounts to 36 min (compartment 1) and 3.6 h (compartment 2) resp. The distribution volume of the substance is11, 100 ml. — 5 metabolites were detected in the urine; 2 of them remained unidentified; the same metabolites could partly be detected in the serum. — As regards the insulin levels, two peaks can be seen following oral as well as following intravenous administration; the first peak is reached after absorption or after the injection as the case may be, the second one is reached at midday postprandially. — Of the orally administered substance, the greatest share of total activity eliminated in the urine is observed during the first 24 h, 65.2% of the administered activity are renally eliminated during 48 h. The corresponding value for 120 h being 65.4% after oral and 64.8% after intravenous administration. — These data verify complete absorption following oral administration.

    Description / Table of Contents: Zusammenfassung An Hand von 5 Fällen einer kongophilen Angiopathie (3 Männer im Alter von 58, 58 und 66 Jahren, 2 Frauen im Alter von 52 und 74 Jahren) wird zur Nosologie und Ätiologie der Erkrankung Stellung genommen. Die klinische Symptomatologie war uneinheitlich. Sie entsprach in 1 Fall einem Morbus Alzheimer, in 1 weiteren Fall einem „atypischen Alzheimer“, in 2 Fällen standen Symptome vasculärer Genese im Vordergrund, in 1 Fall mit „Wurzelreizsyndrom“ und Tod durch Lungenembolie bestanden weder neurologisch noch psychisch irgendwelche Auffälligkeiten. Histopathologisch waren zusätzlich zur kongophilen Angiopathie in allen Fällen senile Plaques gegeben. Alzheimersche Fibrillenveränderungen konnten nur in den 2 Fällen mit Alzheimer-Symptomatik nachgewiesen werden. In je 3 Fällen fanden sich zusätzlich kreislaufbedingte Schäden in Form fokaler Nervenzellverödungen der Rinde sowie in Form von Massenblutungen in verschiedenen Großhirnlappen. Bei diesen Blutungen handelte es sich zweimal um frische tödliche Blutungen, in 1 Fall war die Blutung nach operativer Entleerung knapp 1 Jahr überlebt worden. Für eine Hypertonie als Ursache der Blutungen ergaben sich keine Hinweise. Die Regelmäßigkeit des Vorkommens der kongophilen Angiopathie zusammen mit senilen Plaques und die durch elektronenoptische Untersuchungen gesicherte Tatsache der Amyloidnatur beider Prozesse weisen darauf hin, daß es sich bei ihnen um die morphologischen Ausdrucksformen einer cerebralen Amyloidose handelt (bei der kongophilen Angiopathie um deren Gefäßform, bei den senilen Plaques um die Parenchymform). Es liegt damit morphologisch ein eigenständiger Krankheitsprozeß vor. Er ist gegenüber dem Morbus Alzheimer abzugrenzen, dessen kennzeichnendes morphologisches Substrat, die Alzheimerschen Fibrillenveränderungen, nach elektronenoptischen Untersuchungen nicht mit Amyloid identisch sind. Da die cerebrale Amyloidose in ursächlicher Hinsicht vorrangig als Altersamyloidose anzusehen ist, wird angenommen, daß Alternskrankheiten wie der präsenile Alternsprozeß des Morbus Alzheimer die Entstehung einer cerebralen Amyloidose entscheidend begünstigen. Die häufige Kombination der Erkrankung mit klinischen und histopathologischen Symptomen des Morbus Alzheimer dürfte sich am ehesten durch diese ursächlichen Beziehungen erklären lassen. Die cerebrale Amyloidose kann aber nicht ausschließlich als Altersamyloidose angesehen werden. Es ist derzeit noch ungeklärt, welche anderen Faktoren eine Rolle bei der Entstehung der Erkrankung spielen können. Die ursächliche Bedeutung von Erkrankungen des rheumatischen Formenkreises und erblicher Faktoren wird diskutiert.
    Notes: Summary The nosology and etiology of angiopathy are considered with reference to five cases (3 men aged 58, 58, and 66 and 2 women aged 52 and 74). The clinical symptomatology was not uniform. In one case it was similar to that of Alzheimer's disease, while in another it was similar to that of “atypical Alzheimer's disease”; in two cases vascular symptoms were predominant. One patient with a radicular syndrome died of a pulmonary embolism; neither neurological nor psychological examination revealed any unusual features. Histopathological study revealed senile plaques as well as the congophilic angiopathy. Neurofibrillar tangles were seen only in the two cases with symptom complexes reminiscent of Alzheimer's disease. In three cases there was vascular damage in the form of focal erosion of nerve cells in the cortex and massive hemorrhage in various cerebral lobes. In two cases the hemorrhage was fresh and proved fatal while the other patient survived for just one year after surgical evacuation. There was no evidence for hypertonia as the cause of hemorrhage. The regular occurrence of congophilic angiopathy together with senile plaques and the amyloid nature of both processes (demonstrated by means of electron microscopy) indicate that each of the two conditions is a morphological form of cerebral amyloidosis (the vascular form in cases with congophilic angiopathy and the parenchymal form in cases with senile plaques). Thus, morphologically this is a separate condition which should be differentiated from Alzheimer's disease; examination by electron microscopy reveals that Alzheimer's baskets are not identical with the neurofibrillar changes seen in amyloidosis. As cerebral amyloidosis can be regarded primarily as amyloidosis of old age from the etiological point of view, it is assumed that illnesses due to advancing age, such as Alzheimer's disease, predispose the patient to the development of cerebral amyloidosis. The frequent association of amyloidosis with clinical and histopathologic signs of Alzheimer's disease is most probably due to this causal relationship. Cerebral amyloidosis cannot be regarded exclusively as disease of old age, however. It is still not known what other factors are involved in the illness. The etiological significance of rheumatoid illnesses and genetic factors is discussed.
