    Description / Table of Contents: Zusammenfassung Die Ultraschall-Bestrahlung der Hypophyse, ausgeführt mit der Methode von Arslan, führt zu einer augenscheinlichen Inhibition der hypophysären Funktion. Sie wurde deshalb für die Behandlung der diabetischen Retinopathie angewendet, im Gedanken, daß eine unvollständige Hypophysektomie Vorteile zeitigen kann, die nicht geringer als diejenige der vollständigen Hypophysektomie auf die Evolution der diabetischen Retinopathie sind. Außerdem werden mit der Anwendung dieser Methode die möglichen Komplikationen verhindert, die die chirurgische Hypophysektomie und die mit Radio-Isotopen ausgeführte Hypophysektomie verursachen können. Die Langzeitbeobachtung von 58 an diabetischer Retinopathie erkrankten und mit der Methode von Arslan behandelten Fällen bestätigt das oben Dargestellte. Der Prozentsatz von Besserungen der diabetischen Retinopathie bei unseren Fällen ist folgender: nach Verlauf von 14 Monaten bis zu 6 Jahren nach erfolgtem Eingriff hat die visuelle Schärfe rich bei 31% der Fälle gebessert, bei 53% ist sie unverändert geblieben und bei 16% der untersuchten Augen ist sic schlechter geworden; die objektive Beschreibung der Netzhaut zeigt eine Besserung bei 43% an, ist bei 41% unverändert und bei 16% der untersuchten Augen ergibt sich eine Verschlechterung. Zu betonen ist, daß die Zeichen der Besserung bei einem größeren Prozentsatz zwei Jahre nach dem Eingriff, also nicht sofort nach demselben, zu beobachten sind, während sie in den darauffolgenden Monaten unverändert bleiben.
    Notes: Summary The ultrasonic irradiation of the hypophysis, directly performed by Arslan's technique, leads to a clear inhibition of the hypophyseal function. For this reason, this method has been applied for the treatment of the diabetic retinopathy thinking that an incomplete hypophysectomy can produce advantages not inferior to those of the total hypophysectomy on the evolution of the diabetic retinopathy. Furthermore by this technique, the possible complications of surgical hypophysectomy and hypophysectomy with radio-isotopes are avoided. The study of 58 cases suffering from diabetic retinopathy so treated, confirms these preliminary remarks. The percentage of improvement of the diabetic retinopathy in our cases is the following: at the distance from the intervention, from 14 months to 6 years, the visual acuity has improved in 31% of the cases, it is unchanged in 53%, it is made worse in 16% of the examined eyes; the retinal objective description is improved in 43%, it is unchanged in 41%, it is made worse in 16% of the examined eyes. We must point out moreover that the marks of the improvement are observable in a larger percentage two years after the intervention that not just after the intervention and they are steady the following months.

    Notes: Abstract Gastric mucosal cell migration and proliferation are crucial events in the repair of gastric mucosal erosions. This study was designed to test the hypothesis that the H2 blockers roxatidine and ranitidine might stimulate migration and proliferation of gastric mucous cells derived from a human well-differentiated gastric adenocarcinoma cell line (MKN 28 cells)in vitro, in conditions independent of systemic factors and of acid inhibition. Confluent monolayers of MKN 28 cells were wounded with a razor blade and were then incubated with roxatidine or ranitidine. The number of cells migrating to the damaged area was determined 24 hr later. Cell proliferation was assessed by means of [3H]thymidine uptake and cell counts after incubation with roxatidine or ranitidine. Neither H2 antagonist significantly stimulated cell migration. On the other hand, cell proliferation was dose-dependently and significantly enhanced by incubation with roxatidine and ranitidine. Exogenous administration of TGF-α significantly stimulated MKN 28 cell division. However, incubation with roxatidine or ranitidine did not increase the steady-state mRNA expression of TGF-α or EGFR as assessed by northern blot analysis. Based on thesein vitro findings, we postulate that the ulcer healing effect of these H2 antagonistsin vivo might be due in part to stimulation of gastric mucosal cell proliferation.
