DNA-synthesizing T and non-T cells in bacterial infections.

The results of autoradiographic determination of DNA-synthesizing lymphocytes (3H-thymidine) in 10 patients with bacterial infections were compared with results in 10 normal patients and contrasted with 23 CLL patients in different stages [12]. In patients with infectious diseases the absolute number of T cells was lower and the mean values of S-phase T cells and S-phase non-T cells was higher than in normal persons. In contrast to the patients with infections, CLL patients in stage o--III have lower S-phase T cell values and higher S-phase non-T cell values. In stage IV, on the other hand, all DNA-synthesizing lymphocytes are increased.

[Hematomorphological differential diagnosis of small cell lymphoma. What is the atypical chronic lymphadenosis?].

More importance is being attached to haematologic cell morphology, particularly in the field of small-cell non-Hodgkin lymphomas. This shifting of diagnostical validity from the structural substrate to the cellular one can clearly be illustrated by the transition of classification according to Rappoport to that according to Lennert (Kiel-classification). Here minute cytomorphological criteria acquire a new validity by their significance in the microscopic cut preparation and in the electron-microscope as well as by their correlation to cell-immunological parameters. Thus, it is possible to make a differential diagnostics of the extending small-cell lymphomas from the blood picture. It enables an ensured morphological differentiation to be made for typical B-lymphadenosis, prolymphocytic leukaemia, T-cell lymphadenosis, lymphoplasmocytoid immunocytoma, centrocytoma, and hairy cell leukaemia. The relevance of this differentiation can be further identified by a consequent immunologic cell characterization.

[Comparison of bio-availability, antianaemic efficacy, tolerance and drug costs in oral iron(II) and iron(III) preparations (author's transl)].

In addition to a clinical study which investigated the bio-availability of three oral iron preparations S, L and X by using postabsorption serum iron concentration curves, the same drugs were compared in order to study their antianaemic efficacy, tolerance and drug costs arising during and iron therapy. Moreover, these iron drugs were related to other current clinical reports. Within all three iron preparations a very good correlation was found between bio-availability and haematopoietic efficacy: The very good absorbability of the bivalent quick release stick capsule preparation S (= 100%) corresponded with a very good capacity of haemoglobin regeneration (2,6 +/- 0,4 g Hb/1/day) whereas due to a very low absorbability (10% to 16%) the antianaemic efficacy of both iron(III) preparations L and X had to be rated as moderate to predominantly poor. In normal therapeutic dosis all three iron preparations showed no differences in tolerance. The ratio of side effects was similar to that after ingestion of placebo. In comparing the drug costs during a therapy leading to a real absorption of 1 g of iron the most effective iron(II)sulfate preparation S is 3.6 to 12.6 times cheaper than the compared trivalent preparations L and X. Therefore, there is no justification for the further production or introduction on the market of trivalent iron preparations.

[Kinetics and differentiation of monocytes in man (author's transl)].

This paper gives a short review of the monocytopoiesis in the bone marrow, the kinetics of monocytes in the blood, the differentiation of monocytes in the tissue and presents new data on monocyte transit time through the peripheral blood. Monocyte kinetics were studied in three hematologically normal persons, four patients with Hodgkin's disease and four patients with chroniclymphocytic leukemia using 3H-TdR-pulse-injection or 3H-TdR continuous infusion. The average value of the mean blood monocyte transit time was 25.1 hours. The mean blood transit times of haematologically normal persons and patients with lymphatic disorders did not differ significantly.

[Investigations of the bioavailability of iron from bi- and trivalent iron salts (author's transl)].

In a clinical pilot study, performed as an intraindividual comparison, 3 oral iron preparations, one bivalent iron sulfate (quick release stick capsule preparation) and two trivalent iron citrate complex preparations with different additives, were investigated on 9 healthy young male test persons by the iron absorption test (postabsorption serum iron concentration curves) in order to study the bioavailability of these drugs and their compatibility. Whereas both iron drugs proved equally compatible when administered in therapeutical doses, it was again confirmed that the enteral bioavailability of the ferrous iron sulfate is superior to that of the ferric iron complex preparation. According to these results the medication of ferric iron preparations seems once again to be proved unsuitable, trivalent iron having first to be reduced to bivalent absorbable iron, there however being usually not enough "reducing capacity" in the gastrointestinal tract to do this.

Autotransfusion of 3H-cytidine-labelled blood lymphocytes in patients with Hodgkin's disease and non-Hodgkin patients. II. Exchangeable lymphocyte pools.

The dilution in the circulating blood of lymphocytes lablled in vitro with 3H-cytidine was examined after autotransfusion in 9 patients with Hodgkin's disease (HD) stage II A-IV B, 5 of whom were untreated; in 2 untreated patients with carcinoma, and in 1 treated patient with scleroderma. The blood transit time of exchangeable lymphocytes was 37 +/- 18 min in the patients with HD and 26 +/- 6 min in the other patients. The proportion of exchangeable (recirculating) small blood lymphocytes was 39-84% in HD and 81-91% in the carcinoma patients. The relation between the size of the circulating pool of small blood lymphocytes and the total exchangeable (recirculating) lymphocyte pool was 1:20 to 1:30 in HD and 1:29 to 1:34 in the other patients. The absolute size of the recirculating pool of lymphocytes was 46-90 times 10(9) cells in HD and 100-150 times 10(9) cells in the carcinoma patients.
