    Notes: A novel activation-dependent lymphocyte cell-surface antigen which is recognized by a MoAb, BL Ac(F2), is described. Although not found on resting lymphocytes the antigen is induced rapidly wiihin 2–4 h following stimulation of the cells using mitogens or antibodies against the T-eell CD3 antigen and sIgM on B cells, respectively. Immunopreeipitation and Western Blotting indicated that the MoAb recognizes a molecule in a range of 78 85 kDa. Beyond its activalion-dependent expression on lymphocytes the antigen was detected also on myelo-monocytic cells. Expression kinetics and cellular distribution of this molecule suggest that it is distinct from previously described activation-dependent cell-surface antigens sueh as CD69, CD25 and 4F2.

    Notes: Background Although it is known that the skin acts as a water reservoir and participates in the fluid content of the whole body, no method has been established to quantify the fluid shifts in superficial tissue. Objectives The aim of this study was to investigate changes in dermal and subcutis thickness and echodensity at the forehead and lower leg by high-frequency (20 MHz) ultrasound under various physiological conditions influencing water balance. Methods These parameters were measured in the skin of 20 healthy male volunteers at baseline and successively at 30 min after lying down, in a head-down position, after physical activity and after infusion of 10 mL kg−1 body weight of Ringer’s solution. Results Dermal thickness at the forehead showed a significant increase from baseline to a horizontal position and a further increase in the head-down position. Physical activity did not lead to further changes, whereas after fluid infusion the dermal thickness also increased markedly. The echodensity showed inverse changes, with decreasing values. The thickness of the subcutis increased slightly from baseline to a lying position and decreased in the head-down position and after fluid infusion. At the lower leg, skin thickness decreased slightly in the head-down position with elevated legs, and increased after fluid infusion. Conclusions Our results show that slight changes in the water distribution of the body influence the thickness and the echodensity of the dermis. Changes are more pronounced at the forehead than on the lower legs. Further, the fluid storage takes place mainly in the dermis and not in the subcutis. High-frequency ultrasound is able to quantify these effects and is a sensitive method for measuring fluid intake and balance during anaesthesia and therapy.

    Notes: Abstract Introduction. A recently developed mini ultrasound device for measurement of peripheral tissue thickness is now available for use in clinical practice. Whether this device allows a better guidance of perioperative fluid therapy has to be investigated. Therefore, it is necessary to get basic data on the parameter tissue thickness in otherwise healthy patients during surgery. The aim of the present study was to evaluate differences in tissue thickness change between patients in supine and head down position with a novel handheld ultrasound device during the perioperative course of healthy surgical patients under a standardized fluid regimen. Methods. After obtaining ethics committee approval and informed consent we studied 19 ASA 1–2 female patients undergoing gynecological procedures in supine (SUP, n = 11) or in 30° head down position (HD, n = 8) in general anesthesia. Preoperative NPO status was comparable in both groups. Lactated Ringer's solution (LR) was continuously infused at a rate of 8 ml/kg b.w./h over 90 min and tissue thickness (TT) was determined by ultrasound before induction (t0) and in 30 min intervals (t30, t60, t90) at the forehead. Simultaneously plasma viscosity (PV) was evaluated. Results. Group SUP presented at t0 a forehead TT of 5.3 mm (SD ±0.5), at t30 TT was unchanged. At t60 mean TT increased significantly to 5.6 mm, (±0.6). At t90 mean TT remained stable at 5.7 mm (±0.5). Group HD presented at t0 a mean TT of 4.6 mm (±0.7), at t30 mean TT was 4.9 mm (±0.7) and at t60 mean TT of the forehead skin was measured as 5.3 mm (±0.6). Significance to t0 was reached at t90 with a mean TT of 5.4 mm (±0.7). Group HD showed a steeper increase and a parallel stabilization phase at the end. Differences between t0 and t90 have been significant. Mean PV in the SUP group at t0 (1.361 mPa*s, SD: ±0.045) decreased under the infusion therapy to 1.276 mPa*s (±0.04) at t90. Mean PV in the HD group was determined 1.351 mPa*s (±0.06) at t0 and declined to 1.274 mPa*s (±0.03) at t90. Conclusions.The findings suggest that fluid replacement after an NPO period and the expected changes of forehead TT due to positioning of the patient are detectable by this new ultrasound device.

    Description / Table of Contents: Structural and Magnetic Investigations of Hexachlorotungstates(V)CsWCl6 crystallizes in the monoclinic space group C2/c with the lattice dimensions a = 12.097(8), b = 6.327(5), c = 15.30(1) Å, β = 128.4(1)° and 4 formula units. The compounds AWCl6 (A = Rb, K, NH4) are isotypic with CsWCl6 as shown by powder patterns. Single-crystal photographs of [N(C2H5)4]WCl6 show monoclinic symmetry, space group P21/n with a = 11.737(8), b = 10.239(7), c = 7.191(5), β = 101.46(8)° and Z = 2. Both structures are composed of scarcely deformed WCl6 octahedra. The trigonal compression of the octahedra results in a slightly negative deformation parameter according to the Figgis-model of the magnetic behaviour of d1-systems. Above 80 K the μ2 vs. T-curve is linear. This leads to a spin-orbit coupling constant of 1250 ± 200 cm-1 and a covalence parameter of 0.6-0.8. Comparing the spectra of WCl6, CsWCl6 and Cs2WCl6 the beginning of the charge-transfer region was determined. The crystal field strength for CsWCl6 was found as Δ = 16 000 cm-1.
    Notes: CsWCl6 kristallisiert in der monoklinen Raumgruppe C2/c mit a = 12,097(8) b = 6,327(5), c = 15,30(1) Å, β = 128,4(1)° und Z = 4. Nach Aufnahmen an Kristallpulvern sind die Verbindungen AWCl6 mit A = Rb, K, NH4 isotyp. [N(C2H5)4]WCl6 gehört zur monoklinen Raumgruppe P21/n mit a = 11,737(8), b = 10,239(7), c = 7,191(5) Å, β = 101,46(8)° und Z = 2. In beiden Strukturen liegen schwach trigonal gestauchte WCl6-Oktaeder vor. Für den Figgis-Ansatz zur Deutung des magnetischen Verhaltens führt dies zu einem schwach negativen Verzerrungsparameter und zu einem oberhalb 80 K linearen μ2(T)-Verlauf. Daraus ergeben sich Spin-Bahn Kopplungskonstanten von ∼1250 ± 200 cm-1 sowie Kovalenzparameter zwischen 0,6 und 0,8. Durch Vergleich der Spektren von WCl6, CsWCl6 und Cs2WCl6 ließ sich der Beginn des Charge-transfer-Gebietes festlegen. Die Interpretation führte für CsWCl6 zu einem Kristallfeldparameter Δ = 16000 cm-1.
