Dihydrodiol Dehydrogenase: Substrate Specificity, Inducibility and Tissue Distribution
1982
The present study shows that: Dihydrodiol dehydrogenase activity is present in the 100,000 g supernatant fraction of extrahepatic tissues. Dihydrodiol dehydrogenase is able to oxidize the hydroxy group and to reduce the keto group of a number of xenobiotics including quinones derived from polycyclic aromatic hydrocarbons. Dihydrodiol dehydrogenase was not inducible by various substances including hormones, polycyclic aromatic hydrocarbons, substrates of the enzyme and potent inducers of monooxygenases, epoxide hydrolase and glutathione S-transferases. Only in the case of thyroxine was a weak induction with a high dose of the hormone observed.

Palais et fisc à l'époque carolingienne: Attigny
1982
Domaine rural acquis par Clovis II en 651, Attigny fut une résidence du maire du palais Pépin à partir de 749. Devenu un palais avec l'avènement des Carolingiens, il cessa d'être fréquenté après 931. La fonction essentielle de ce palais découle de sa situation géographique située à proximité de la voie romaine Reims-Trêves, la localité constituait une étape commode entre est et ouest du royaume franc, puis entre les royaumes de Francie occidentale et de Lotharingie. Le fisc d'Attigny, mentionné pour la première fois en 877, peut être connu par l'analyse de trois diplômes, dont deux très postérieurs à la période carolingienne. Il englobait au début du Xe siècle au moins trois mille cinq cent…

Intramitochondrial crystalloids in rat pinealocytes.
1982
In the present study the rare occurrence of intramitochondrial crystalloid inclusions in the rat pinealocytes is described. They lie within the mitochondrial matrix and consist of a lattice of moderately electron-dense lines. Intersections at regular intervals form rhomboid-like subunits. The significance of these inclusions is not known.

Conservative Surgery of Renal Carcinoma: The EIRSS Experience
1981
Summary— Seventy-two patients with renal carcinoma (RC) in a solitary kidney or bilateral synchronous tumours underwent parenchyma-sparing excision of their neoplasms. This was performed in situin 51 and extracorporeally in 21 kidneys, with a complication rate respectively of 1 7 and 43%. The 5-year survival rates were 78% for unilateral disease, 48% for bilateral synchronous and 38% for bilateral asynchronous disease. Survival correlated with Pcategory, grade and diameter of the tumour. Vascular invasion and spindle cells indicated a poor prognosis; the position of the tumour, oncocytic elements, calcification, lymphocytic infiltration or the predominance of clear cell or granular cells di…
Report on a very young dizygotic human twin pregnancy.
1981
Two ova implanted in one uterus were found at the autopsy of a 28-year-old woman. The ovulation age of both implantations has been estimated to be 10–12 days. The presence of two equally large corpora lutea, one in each ovary, indicates that the implanted ova originated from different ovaries. Thus, an “ovulatio biovarialis” seems to be the basis for the dizygotic twinning in this case. The case is believed to be the only documented example of a very early dizygotic, fraternal pregnancy in humans.
High resolution analysis and differential condensation in RBA-banded human chromosomes.
1981
Human prophase, premetaphase, and mid-metaphase chromosomes are prepared and analyzed using the thymidine cell synchronization technique and R-banding patterns (RBA). Haploid sets with 700–1000 bands can be demonstrated. Sequences of chromosomes of different degrees of condensation are helpful for a better understanding and classification of regions of extended chromosomes. A considerable variation in the condensation of parts of homologous chromosomes is reflected in the variability of the arm ratio. This differential condensation of chromosomes is entirely effected by variation of the degree of condensation in AT rich interbands and can be attributed to the degree of labeling by BrdU.

1981
In experimental tubulo-interstitial (anti-basement membrane) nephritis of the rat, granulomatous inflammation develops around immunologically altered tubular basement membranes. The present light- and electron microscopic studies indicate that in the course of the granulomatous reaction, tissue monocytes evolve from blood monocytes and pursue two independent pathways of differentation. On the one hand they may differentiate into macrophages ("distant from tubules") or, alternatively, into epitheloid cells ("adjacent to tubules"). The latter, through cell fusion, develop into multinucleated giant cells of the Langhans' type. The cytoplasmic components of the epitheloid cells and the multinuc…
Addition reactions of azoesters with 2-thioquinazolinones
1981
Reaction between diethyl azodicarboxylate (I) and 1,2,3,4-tetrahydro-2-thioquinazolin-4-one (II), as a cyclic model of thiourea, both in alcoholic medium and in inert solvents has been investigated. By carrying out the reaction in an inert solvent, it was possible to isolate an intermediate. Evidence is presented that the intermediate, in turn, was converted into the final products. Structures were unequivocally assigned by mass spectrometry.
Effect of ouabain and furosemide on erythrocyte sodium and phosphate transport.
1981
The effects of ouabain and furosemide on the unidirectional efflux of sodium and phosphate ions were studied in freshly drawn human red blood cells (RBCs). In the presence of physiologic concentrations of sodium and potassium the rate of sodium efflux was reduced by 74% due to ouabain sensitivity. Furosemide (1.0 mmol/l) reduced ouabain-insensitive sodium transport rate by a further 50%. Thus, 13% of total sodium efflux was inhibited by furosemide when ouabain was present. In the absence of ouabain, however, furosemide inhibited 31% of total sodium transport, indicating that it also affected ouabain-sensitive sodium efflux. Phosphate transfer of RBCs was almost 1.0 mmol/l RBCs per hour. Ery…
154. Wandel des diagnostisch-therapeutischen Konzepts beim malignen Verschlu�ikterus
1981
Die modernen diagnostischen Untersuchungen wie CT und Sonographie kombiniert mit der PTCD fuhren zu einem Wandel des diagnostisch therapeutischen Konzepts beim malignen Verschlusikterus. Invasive Verfahren wie die Angiographie sind selten indiziert, und einer zunehmenden Zahl von Patienten mit inoperablem Pankreascarcinom kann die ineffektive explorative Laparotomie erspart werden. Die Rate an kurativen Resektionen wird nicht beeinflust.
Cross Sections of232Th (p,xn+yp) Reactions at Ep= 6.8 to 20.2 MeV
1981
Cross-sections for the (p, n), (p, 2n), (p, 3n) and (p, pn) + (p, d) reactions on 232Th targets were measured, by comparison with the K-shell ionization cross-section, for proton energies between 6.8 and 20.2 MeV. The results are compared with the predictions of the statistical and the pre-equilibrium model. For the (p, pn) reaction, the "clean knock-out" model is also considered.
Pressure dependence of the demixing of polymer solutions determined by viscometry
1981
From the break-down in the viscosity of a polymer solution, associated with the entrance into the two phase region, the pressure dependence of the demixing temperatures of solutions of polystyrene (M = 600.000) in cyclohexane, cyclopentane, diethylmalonate and 1-phenyldecane was measured up to 1000 bar. The application of pressure increases the solubility of polystyrene in cyclopentane and diethylmalonate, but decreases that in 1-phenyldecane; in the case of cyclohexane, a pressure of optimum miscibility is observed at ca. 120 bar.
On the accurate determination of nonisolated solutions of nonlinear equations
1981
A simple but efficient method to obtain accurate solutions of a system of nonlinear equations with a singular Jacobian at the solution is presented. This is achieved by enlarging the system to a higher dimensional one whose solution in question is isolated. Thus it can be computed e. g. by Newton's method, which is locally at least quadratically convergent and selfcorrecting, so that high accuracy is attainable.
Modulated magnetic structures of ErPb3, HoPb3, ErTl3 and HoTl3
1981
Neutron diffraction experiments have been carried out on the magnetically ordered phases of ErPb3, HoPb3, ErTl3 and HoTl3. The magnetic moments were found to be sinusoidally modulated with a propagation vector of (0, 0.2, 0.5) for the Pb-compounds and (0.38, 0.38, 0.16) for the Tl-compounds.

Fine Structure of the Tunic ofCiona intestinalisL. II. Tunic morphology, cell distribution and their functional importance
1981
Ciona intestinalis L. tunic architecture and cell distribution were investigated with the electron microscope. The observations showed that the ascidian covering is formed by a thin outer cuticle, a subcuticle of variable width and a large single layer of ground substance. “Large granule”, morula, phagocyte and granulocyte are the cellular types encountered; they appear mainly in highly vacuolated states and are distributed throughout the whole tunic. The “large granule” cells, however, are mainly seen in the cuticle layer and the morula cells appear mostly in the outer zone of the ground substance. The role of these cells in tunic construction, repair and regeneration as well as their scav…
Comparative study on biological activities of various anaphylatoxins (C4a, C3a, C5a)
1981
Several anaphylatoxic substances (human C3a, guinea pig C3a, human C4a, guinea pig C5a, and a synthetic C3a-related hexapeptide) were compared with regard to their ability to induce secretion of [3H] serotonin from guinea pig platelets. Functional identity of the C3a preparations, C4a, and the hexapeptide was demonstrated by the phenomenon of crossed desensitization. Whereas C3a of human and guinea pig origin proved to be qualitatively and quantitatively identical, C4a expressed only 3% of the activity of the C3 fragments on a molar basis. Investigations with goat anti-guinea pig C3a demonstrate that human and guinea pig C3a possess one antigenic determinant in common; however, this determi…
Does uremic enterocolitis exist?
1981
In rats a severe but compensated chronic renal insufficiency was induced by stepwise 9/10 nephrectomy. Despite this severe chronic renal insufficiency we observed no relevant pathological changes in the intestinal mucosa. In particular, we found no evidence of mucosal erosions, ulceration or pseudomembranous colitis, findings which are traditionally thought to be characteristic of the uremic state. This was also true of those animals dying prematurely from uremia. Thus serious doubts arise about the existence of “uremic enterocolitis”, doubts which also proved justified after a critical review of the literature on human pathology.
