    Description / Table of Contents: Zusammenfassung Die Hyperkalzämie ist häufig bei hyperthyreoten Patienten und ist durch eine osteoklastische Aktivität der thyroidalen Hormone verursacht. Die Ergebnisse dieser Arbeit zeigen, daß eine Hyperkalzämie sich signifikant häufiger in älteren Patienten und bei einer bestimmten Kropfform entwikkelt. Gemessen wurden das gesamte Serumkalzium, Gesamtproteine, Albumin sowie an Schilddrüsenparametern T3 RIA, T4-Test, ETR- und TRH-Test in einer Gruppe von 147 Patienten. Der Spiegel des ionisierten Kalziums wurde aus dem Gesamtkalziumwert und aus dem Albuminwert berechnet. Insgesamt 211 Messungen wurden durchgeführt. 92 Patienten waren hyperthyreot. Das Gesamtkalzium war in der Hyperthyreose nicht signifikant erhöht. Das ionisierte Kalzium war bei hyperthyreoten Patienten unter 61 Jahren nur in 2,3%, bei Patienten über 60 Jahren jedoch mit 18,8% signifikant erhöht. Bei 43,8% der hyperthyreoten Patienten mit multinodösen Strumen fand sich eine Erhöhung des ionisierten Kalziums im Serum. Die lineare Korrelation zwischen dem ionisierten Kalziumspiegel und den verschiedenen Schilddrüsenparametern war in der älteren Gruppe deutlicher als in der jüngeren und hoch signifikant. 7 von 9 hyperthyreoten Patienten mit erhöhtem ionisiertem Kalzium hatten eine Knotenstruma, jedoch kein autonomes Adenom. Die direkte Schilddrüsenhormonwirkung und die besondere Kropfform können für die Entwicklung der Hyperkalzämie verantwortlich sein. Die Möglichkeit eines Kalzitoninmangels wird diskutiert.
    Notes: Summary Hyperthyroidism is often associated with hypercalcemia which is provoked by osteoclastic activity of the thyroid hormones. These data show that hypercalcemia develops with increasing age and in the presence of a special type of hyperthyroid goiter. Total serum calcium, total protein, and albumin as well as different parameters of thyroid function, namely T3 RIA1, T4 test, ETR and TRH test were determined in a group of 147 patients. The ionized calcium level was estimated from total calcium and albumin. 211 measurements were performed. Hyperthyroidism existed in 92 cases. Total calcium was not significantly elevated in hyperthyroidism. Hyperthyroid patients under 61 years of age showed elevated ionized calcium levels in only 2.3% and patients over 60 years of age in 18.8% of cases. Elevated ionized serum calcium levels were observed in 43.8% of hyperthyroid patients with multinodular goiters. The linear correlation between ionized calcium levels and different parameters of thyroid function is much more pronounced in the older group and it was found to be highly significant. 7 of 9 hyperthyroid patients with elevated ionized calcium levels showed multinodular goiters, though no autonomous adenoma. In the hyperthyroid group of patients of over 60 years of age with multinodular goiters the incidence of hypercalcemia was 43.8%. Direct action of thyroid hormone on calcium turnover as well as increasing age and special goiter type seem to be responsible for disturbances in calcium metabolism. A possible calcitonin deficiency in the above mentioned conditions is discussed.

    Description / Table of Contents: Zusammenfassung Der klinische Verlauf zweier Patienten mit primärer Hypomagnesämie wird beschrieben. Bei einem Patienten, einem 5 Monate alten Säugling, wurden Magnesiumretention,-resorption,-Stuhlausscheidung und-Clearance gemessen. Die Retention (2,8%) und Resorption (7,8%) von Magnesium28 war deutlich erniedrigt im Vergleich zu Kontrollpersonen, die durchschnittlich 25% retinierten und 28% absorbierten. Zwischen den Retentionswerten der Eltern und Verwandten und denen der gesunden Erwachsenen bestand kein Unterschied. Der untersuchte Patient wurde erfolgreich mit Trimagnesiumdicitrat, entsprechend einer Dosis von 1,75 g Magnesium, behandelt.
    Notes: Abstract The clinical course of 2 patients with primary hypomagnesemia is reported. In one male patien, 5 months old, measurements of magnesium retention, intestinal absorption, fecal excretion and renal clearance were performed. The retention (2.8%) and absorption (7.8%) of 28-Mg were markedly reduced in comparison to controls (average retention 25% and average absorption 28%). The retention values of the parents and other relatives did not differ from those of healthy adults. The examined patient was successfully treated with trimagnesium dicitrate containing 1.75 g magnesium per day.

    Description / Table of Contents: Zusammenfassung Bei 3 Patienten mit Akrodermatitis enteropathica wurde mit Hilfe der Ganzkörpermessung nach oraler Applikation von 65Zn eine verminderte intestinale Zinkresorption gedunden. Dagegen war die Zinkelimination aus dem Körper normal. Die Zinkkonzentration im Serum war bei den Patienten stark erniedrigt. Alle klinischen Symptome verschwanden nach sehr hohen oralen Zinkdosen. Diese Befunde sprechen um so mehr für eine ursächliche Rolle des Zinks in der Pathogenese der Akrodermatitis enteropathica, als bei dieser Krankheit ultrastrukturelle Veränderungen in den Panethschen Zellen nachzuweisen sind [12], die auch beim Zinkmangel der Ratten gefunden wurden [Beitr. Path. 145, 336 (1972)].
    Notes: Abstract The intestinal resorption of zinc using 65ZnCl2 was estimated in 3 patients with acrodermatitis enteropathica, 2 healthy controls, and 3 heterozygotes. After oral application of 65Zn the whole body activity was measured by a whole body counter for 34 days. The 65Zn resorption of the patients amounted to 16, 42 and 30% of the applied dose, whereas the resorption values of the heterozygotes and the controls were in the range of 58 and 77%. The elimination of 65Zn from the body amounted to about 0.7% of the applied dose with no difference between controls and patients with acrodermatitis enteropathica. Before therapy the serum-zinc levels of patients were markedly decreased. After oral application of high doses of zinc aspartate (2×400 mg/day) all clinical symptoms disappeared within a week. The results point at a causal connection between zinc and the pathogenesis of acrodermatitis enteropathica. Ultrastructural alterations of the Paneth cells of the intestine are also shown in this disease [12] as have also been seen in Paneth cells of zinc deficient rats [Beitr. Path. 145, 336 (1972)].

    Notes: Zusammenfassung 1. Es wurde die Konzentration desoxydierten Diphosphopyridinnucleotids im menschlichen Blut bestimmt; bei Gesunden fand sich ein Wert von 19,26γ DPNox. ± 3γ/ml Blut im Mittel. 2. Unter der Therapie mit E 39 und Endoxan bei inoperablen Tumorkranken fällt der DPNox.-Spiegel ab. Ist bei der Behandlung mit E39 das DPNox. auf 12γ/ml Blut abgesunken, so soll die Therapie abgebrochen werden. Bei einer Endoxan-Medikation kann das DPNox. bis auf 10γ/ml Blut gesenkt werden. 3. Es wurde der DPNox.- und DPNred.-Gehalt pro Leukocyt an Hand isolierter Leukocyten bestimmt. 4. Es konnte keine Erniedrigung des spezifischen DPN-Gehaltes der Leukocyten durch die cytostatische Therapie festgestellt werden.

    Notes: Summary Carrier-free11C-labeled carbon monoxide was produced by proton irradiation of a nitrogen gas flow targetvia the14N(p,α)11C process followed by on-line reduction of the predominantly formed11C-carbon dioxide with a yield of 0.4 mCi/µAmin. After appropriate quality control about 2 mCi of carrier-free11C-carbon monoxide in 500 ml of nitrogen gas were inhaled by test subjects in one breath. The11C-activity distribution was then followedin vivo by scanning above thorax, head, liver, thigh andos sacrum; simultaneously the11C-activity of the blood was also followed by batch measurement. The data indicate that part of the11C-activity migrates from the blood into the intercellular space, while another part is exhaled. The11C-activity leaves the individual organs with a biological half-life ranging from about 120 to 200 min, a time which is short as compared to the one observed for51Cr-labeled erythrocytes. A radio gas chromatographic analysis of the exhaled air showed that the11C-activity leaves the body exclusively in the form of11C-labeled carbon monoxide. Consequently, metabolism of the11CO into11CO2 or other compounds can be excluded.

    Notes: Summary During a follow-up of 11 years of thyroid carcinoma 136 patients were repeatedly examined. 43% papillary, 43% follicular, 11% anaplastic and 2% medullary carcinomas was found. The incidence of these types of carcinoma differed considerably; the frequency peak of papillary carcinomas was reached in 45-year-old humans, that of the follicular carcinomas in people aged 60, that of the anaplastic carcinomas in 70-year-old humans. 84% of the patients was female. Classification in pTNM-system: 8% in pT1, 27% in pT2, 12% in pT3 and 49% in pT4. Local and distant metastases were found at a low rate equally in pT1, pT2 and pT3; 26% of patients in pT4 had local metastases and 18% had distant ones in addition. There were 6 patients with metastases of a differentiated adenocarcinoma accumulating no 131-iodine and with no thyroglobulin in serum. 29% of patients had after thyroidectomy an unilateral paresis of the nervus recurrens and 4% a bilateral one. 26% of patients had a permanent hypoparathyroidism after thyroidectomy.
