    Notizen: CdTe epitaxial films were grown by a simple method of temperature gradient vapor transport deposition on p-InSb (111) orientation substrates in the growth temperature range between 200 and 280 °C. Raman spectroscopy showed the optical phonon modes of the CdTe thin films and the formation of an indium telluride interfacial layer in the CdTe/InSb heterostructures. The stoichiometry of the CdTe/InSb heterostructures was observed by the Auger electron spectroscopy, and Auger depth profiles also demonstrated that the CdTe/InSb heterointerface was not abrupt. The results indicated that the films grown at about 265 °C posed a significant problem due to interdiffusion from the InSb substrates during the growth.

    Notizen: Abstract Kidney vetch seedlings were induced to form hairy roots by inoculating their mesocotyls with the wild-type strain 15834 of Agrobacterium rhizogenes or with the A. tumefaciens strain C58C1 containing a binary vector system (the pRiA4b as a helper and the vector pCB1346 bearing a pTiC58-derived isopentenyl transferase gene (ipt, cytokinin biosynthetic gene) under control of its native regulatory sequences). Transgenic lines of three distinct phenotypes were selected: (i) Typically, the pRi15834-transformed tissues were stabilized in vitro and maintained for long periods as aseptic, fast-growing, hormone-independent, plagiotropic hairy root cultures which never regenerated shoots and lost the ability to synthesize opines. Their genomic DNA contained both the TL- and the TR-DNA. (ii) One of the HR-lines transgenic for the T-DNA of pRi15834 (named 52AV34) started to regenerate spontaneously into teratomous shoots. The shoots were found to produce opines and both the TL and TR parts of T-DNA were found to be partly deleted and/or rearranged. They contained phytohormones in similar levels as those found in seed-born shoots. (iii) A practically identical morphogenic response as in the line 52AV34 was observed in the clone 27AV46. However, its shooty, dark-green, slow-growing teratomas were proven to be kanamycin-resistant, opine-producing, and double-transformed by the pRiA4b sequences and the ipt gene. They over-produced auxins as well as cytokinins (mainly indoleacetylaspartic acid and ribosides of zeatin and isopentenyladenine).

    Beschreibung / Inhaltsverzeichnis: Résumé Les auteurs présentent les résultats de 36 ostéotomies inter-trochantériennes effectuées pendant une période de 15 ans. Les indications chirurgicales ont été les suivantes: déplacement chronique de la tête fémorale avec un angle tête-col (ATC), mesuré sur la radiographie de profil, supérieur à 30°, associé à un signe de Trendelenburg positif et/ou une marche en rotation externe. L'âge moyen des malades au moment de l'opération était de 14,1 ans. Le recul moyen des observations est de 7,5 ans. Deux fois l'ostéotomie a du être reprise précocément durant la période post-opératoire à cause d'un redéplacement. Les complications les plus importantes ont été deux nécroses de la tête fémorale et quatre coxa vara. L'ATC a diminué en moyenne de 30°. Les résultats ont été évalués selon la cotation d'Ireland et Newman: il y a 14 bons, 18 médiocres et 4 mauvais résultats cliniques et 13 bons, 19 médiocres et 4 mauvais résultats radiologiques. Les meilleurs résultats ont été obtenus avec un ATC final de moins de 10°.
    Notizen: Summary Thirty six patients with a chronic slip of the capital femoral epiphysis and a femoral headneck angle of more than 30 degrees, as measured in a lateral radiograph, were treated by intertrochanteric osteotomy. The patients had an abnormal gait, an average age of 14.1 years and symptoms for an average of 14.5 months. The postoperative complications included two patients with avascular necrosis of the femoral head, four with coxa vara and two with loss of position requiring further operation. At an average of 7.5 years after operation 14 were good, 18 fair, and 4 poor on clinical assessment, with 13 good, 19 fair and 4 poor when judged by radiographs. Patients with complications had only fair or poor results. A postoperative head-neck angle of less than 10 degrees indicated a good result.

    Notizen: Abstract Ascorbate treatment 30 min prior to sodium dichromate (20 or 30 mg/kg, s.c.) shows higher potency than that of glutathione (GSH) in protecting against both the metabolic disturbance and nephrotoxicity induced by dichromate. However, ascorbate treatment after 2 h of dichromate intoxication had no effect on dichromate-induced blood urea nitrogen (BUN) elevation 3 days after intoxication. In contrast, dichromate-induced glucosuria, which reached maximum levels at 3 days after treatment, was significantly decreased by GSH or N-acetyl cysteine (NAC) treatment, even if its administration was after 24 h of dichromate intoxication. Pretreatment with GSH depletors such as diethyl maleate (DEM) and buthionine sulfoximine (BSO) had no effect on dichromate-induced nephrotoxicity. GSH levels in the liver and kidney were not affected at 3 h after dichromate treatment. However, dichromate significantly increased tissue GSH levels with a marked increase in liver per kidney GSH ratio at 24 h after treatment, if food was withheld subsequent to dichromate treatment, indicating that GSH biosynthesis resulted from the accelerated protein breakdown. These results suggest that GSH-mediated dichromate reduction is not a kinetically favorable pathway in vivo; however, GSH plays an important role in protection against dichromate-induced nephrotoxicity. In addition, the cellular metabolism of dichromate in the early period after treatment is important in the pathogenesis of its nephrotoxicity.

    Notizen: Summary The kinetics of a single oral dose of mefloquine given either alone or with tetracycline has been studied in 20 healthy Thai male volunteers. There was a significantly higher maximum whole blood mefloquine concentration after coadministration with tetracycline (1600 vs 1160 ng · ml−1), as well as a significantly reduced terminal half-life (14.4 vs 19.3 days), mean residence time (11.9 vs 16.0 days) and volume of distribution at steady state (13.3 vs 19.91 · kg−1). Although there was no significant change in the AUC from zero time to infinity, the AUC from zero time to 7 days was significantly increased by tetracycline (6.18 vs 4.76 μg · ml−1 · day). The changes in mefloquine disposition after tetracycline treatment are probably due to a reduction in enterohepatic recycling. The initial increase in mefloquine AUC without an apparent increase in side-effects suggests that this combination may have a place in the treatment of multi-drug resistant falciparum malaria.

    Notizen: Abstract Most of the existing plotting position formulas have been proposed for use in the analysis of systematic flood records, but little has been reported on the plotting formulas for historical or non-systematic flood samples. In particular, no previous investigations have specifically examined the probability plots for the Pearson type III (P3) distribution in the analysis of historical flood information. The present paper suggests a new plotting position formula for the P3 distribution for use with both systematic and historical flood records. The proposed formula has a simple structure as do most existing formulas, but it is more flexible because in can take explicitly into account the skewness coefficient of the underlying distribution. Further, results of graphical and numerical comparisons have demonstrated that the suggested formula provided the least bias in flood quantile estimation as compared with many available plotting formulas, including the well-known Weibull formula. Finally, results of a numerical example using actual flood data have indicated the practica convenience of the proposed plotting formula. It can be concluded that the formula developed in this study is the most appropriate for the P3 distribution in the analysis of flood records considering historical information.

    Notizen: Abstract The authors present examples of the significantly improved diagnostic imaging for cystic lesions in the jaw bone, floor of the mouth and maxillary sinus with Gadolinium-DTPA (Gd-DTPA) enhanced MRI. Twelve cases of cystic lesions, which were 6 cases of intra-osseous odontogenic cysts and cystic tumors, 2 cases of epidermoid cysts in the floor of the mouth and 4 cases of cystic polyp of the maxillary sinus. Improved MR images provided useful information delineating the thickness of circumscribed soft tissue wall (cystic wall), the location of the intra-cystic substance and the configuration of the tumor masses.
