    Notes: Abstract The magnetostriction (MS) of REBa2Cu3O7−δ (RE=Y, Nd, Eu, Gd, Ho, Er, Yb) is reported as a function of magnetic field and temperature forH〈5 T and 1.5〈T〈40 K. With nonmagnetic rare earths the MS is small and a linear function of the field atH〉1 T. The MS is much larger when the rare earth carries a magnetic moment, as usual, but the volume MS observed with moment carrying REBa2Cu3O7−δ is larger than that of nonsuperconducting intermetalics. This effect is explained by the shielding currents which are induced by the 4f magnetic moments in the superconducting CuO-lattice. The thermal expansion of GdBa2Cu3O7−δ shows a large peak at the ordering temperature of 2.2 K in both the superconducting and the nonsuperconducting samples.

    Description / Table of Contents: Résumé Les coupes axiales d'épaule obtenues en IRM montrent une bande linéaire centrale à l'intérieur du m. supra-épineux, vide, qui ne semble pas représenter uniquement le tendon de ce muscle. En raison de l'importance du m. supraépineux dans les syndrômes douloureux de l'épaule, nous avons étudié l'architecture fibreuse de ce muscle, en comparant 30 imageries par résonnance magnétique nucléaire et 49 dissections cadavériques. Nous avons trouvé que le m. supra-épineux était composé de deux parties distinctes. La longueur moyenne de la partie ventrale est de 88 mm et celle de la partie dorsale de 106 mm. L'angle du tendon central qui est formé par les fibres des deux parties musculaires, fait 50° avec le plan frontal. Les deux parties musculaires agissent probablement différemment dans les mouvements du bras. Ces constatations semblent être importantes pour la physiopathologie des ruptures de la coiffe des rotateurs, qui sont principalement situées en avant, dans la partie ventrale du muscle et dans le tendon central excentrique.
    Notes: Summary Axial MR images of the shoulder joint reveal a central linear band within the supraspinatus muscle void of signal which seems not to represent the only tendon of this muscle. Due to the importance of the supraspinatus muscle for the painful impingement syndrome of the shoulder we studied the fibrous architecture of this muscle comparing 30 MR images and 49 cadaver dissections. We found the supraspinatus muscle to be composed of two distinct portions. The mean length of the ventral portion is 88 mm and of the dorsal portion 106 mm. The angle of the central tendon which is formed by fibers of both muscle portions relative to the frontal plane is 50°. Both muscle portions probably act differently in moving the arm. This finding seems to be important for the pathophysiology of rotator cuff tears which are mainly located anteriorly within the ventral muscle portion and the eccentric central tendon.

    Notes: Abstract In the human placenta, besides the fetal blood vessel system a second extravascular contractile system exists. It is localized in the chorionic plate and runs in a longitudinal direction and adjacent to fetal blood vessels into the stem villi, where it forms perivascular contractile sheaths. Characteristically, cells of the extravascular contractile system are extremely long and spindle-shaped and give rise to fine cell processes, by which they obviously contact each other or insert into the basement membrane of the trophoblast. They show immunoreactivity with desmin, vimentin, α-actin, myosin, nitric oxide synthase type I (brain form) and dipeptidyl peptidase IV. The ultrastructure suggests that cells of the extravascular contractile system are related to smooth muscle cells, including subpopulations with myofibroblastic features. In stem villi a few cells are nitric oxide synthase type I immunoreactive. These cells are thought to be specialized smooth-muscle-like cells of the extravascular contractile system or cells of the extravascular contractile system related to paraneurons that generate nitric oxide, which, in turn, may modulate the tone of perivascular contractile sheaths. The high dipeptidyl peptidase IV activity suggests that modulation of the extravascular contractile system may also occur by substance P.

    Notes: Summary Bone marrow transplantation was performed between IV/82 and X/85 in 64 patients with acute leukemia (n=36), chronic myelogenous leukemia (CML;n=13), severe aplastic anemia (n=12), and neuroblastoma stage IV (n=3). Of these patients 57 received allogeneic marrow from HLA-ABCDR identical, MLC-negative sibling donors. Six transplants were performed with syngenic marrow and one with autologous marrow. Of the 64 patients 48 survived 40-1,250 days after transplantation, resulting in a survival rate (SR) of 75% and a survival probability (SP) of 71%. Of the 36 patients suffering from acute leukemia (SR=64%, SP=51%), patients with acute myelogenous leukemia (AML) in first complete remission (n=11; SR=81%, SP=76%), as well as patients with acute lymphatic leukemia (ALL) in 1st to 4th complete remission at the time of transplantation (n=14; SR=81%, SP=76%) show a favorable prognosis. A poor survival rate was seen for patients with AML when transplanted in second or partial remission (1/5; SR=20%), as well as for patients suffering from ALL and transplanted during relapse or partial remission (1/6; SR=16%). Of 13 patients suffering from CML 12 survived the transplantation free of relapse (SR=93%, SP=92%), and one patient died from varicella zoster pneumonia. Of the transplanted patients with severe aplastic anemia, 12 of 13 are surviving with complete hematologic reconstitution; one patient, however, died on day 10 from a sepsis. In our patient group, the SR as well as the SP has been improved through changes in the irradiation protocol concomitant with prophylactic application of anti-CMV hypergammaglobulin, as well as through additional oral medication of Azyklovir. The 41 patients (BMT No. 7–47) with total body irradiation at one time-show an SR of 44% and an SP of 41%. The following 46 patients (BMT No. 48–93) have reached an SR of 83% and an SP of 74% under the regimen of fractionated total body irradiation, plus prophylaxis with anti-CMV hypergammaglobulin and Azyklovir. Within this group, no fatal CMV pneumonia was encountered as opposed to six patients lost from CMV pneumonia in the first group.

    Notes: Summary Viral infections are one of the major complications after bone marrow transplantation, with high mortality and morbidity. Fourty-six patients between 3 and 48 years old (median 15 years) received orally 400 mg (under age 6, 200 mg) acyclovir 4 times daily from day −12 before to day 84 after BMT. All patients were isolated in laminar-airflow units for at least 23 days with total enteral decontamination. They were concomitantly treated with anti-CMV-hyperimmunoglobulin and cotrimoxazol. During acyclovir prophylaxis seven patients had herpes simplex virus infections, all of them were seropositive before BMT. Acyclovir plasma concentrations were measured by use of a new HPLC method. No acyclovir was present (detection limit 40 ng/ml) in the plasma of five out of six patients with HSV infections. Three of them had non-compliance, and a lack of acyclovir absorption developed in two patients under conditioning regimen. No drug-related side effects were observed. Laboratory tests did not show liver or renal toxicity. Take and hematologic reconstitution were unchanged. In our study, oral acyclovir reduced the incidence of herpes simplex infections after bone marrow transplantation. Herpes infections only occurred in patients with non-compliance or lack of acyclovir absorption.

    Notes: Summary Even though the enhancement of the lyitc capacity and the kinetics of lysis of natural killer cells (NK) by interferon has been well documented, an increase of the target-effector cell binding percentage is still disputed. We, therefore, modified the Grimm-Bonavida single-cell assay so that 400 to 600 cells per individual determination could be reliably evaluated. Using this assay, which makes possible separate determination of effector-target cell binding and target lysis, we demonstrated that, in addition to lytic capacity, target-effector cell binding is also increased by preincubating NK with 100 to 1,000 IU interferon alpha 2 per 106 cells. Our data indicate that interferon alpha 2 induces pre-NK cells to bind target cells and that it activates these pre-NK cells to kill the targets.
