Effects of melatonin on ovarian follicles

Objective: To evaluate the histomorphometry and expression of Ki-67 and c-kit in ovarian follicles of pinealectomized or melatonin-treated pinealectomized rats.Study design: Forty adult rats were randomly divided into four groups of 10 animals: Group I - control; Group II - sham-pinealectomized; Group III - pinealectomized (Px), and Group IV - Px treated with melatonin (10 mu g/night, per animal). After two months' treatment, on the night of proestrous, the animals were placed in metabolic cages for night urine collection and subsequent measurement of 6-sulfatoxymelatonin (6-SMT). the rats were anesthetized, blood samples were taken for estrogen and progesterone determinations, and they were then euthanized. the ovaries were dissected out for further histological and immunohistochemical analyses. Data were first submitted to analysis of variance (ANOVA) complemented with the Tukey-Kramer test for multiple comparisons (P < 0.05).Results: the urinary levels of 6-SMT and serum progesterone were lower in the Px group (GIII). Exogenous melatonin treatment restored both blood melatonin and 6-SMT urinary levels. the histomorphometric data in Group III revealed a significant increase of degenerating antral and nonantral follicles with regard to the other groups. in addition no corpora lutea were observed in this group. No significant differences were noticed regarding the number of corpora lutea among the other groups (I, II and IV), but the number of cells and the thickness of the theca interna of Px animals (Group III) were higher than in the other groups. Conversely, the density of progesterone receptors (fmol/g) in the ovaries of Group III was significantly lower than in the other groups.Conclusion: Our data indicate that melatonin exerts a role on the maintenance of a proper follicular function, and is thus important for ovulation and progesterone production.

Angiosarcoma, porphyria cutanea tarda, and probable chloracne in a worker exposed to waste oil contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin

A worker developed angiosarcoma, porphyria cutanea tarda, and skin lesions characteristic of mild chloracne. About 10 years earlier he had been employed at a truck terminal in Saint Louis, Missouri, at a time when it was sprayed with waste oil contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The occurrence of these three rare conditions in a single exposed worker supports the aetiological relation between environmental exposure to TCDD and the subsequent development of soft tissue sarcoma and porphyria cutanea tarda.

The role played by angiotensin (1-7) in the regulation of renal haemodynamics and excretory function in anesthetized rats

Initial studies have demonstrated that intra- renal infusion of Ang (1-7) caused a diuresis and natriuresis that was proportional to the degree of activation of the Renin Angiotensin Aldosterone System (RAAS). This raised the question as why the magnitude of this diuresis and natriuresis was compromised in rats receiving a high sodium diet (suppressed RAAS) and enhanced in low sodium fed rats (activated RAAS)? Could the answer lie with changes in intra-renal AT1 or Mas receptor expression? Interestingly, the observed Ang (1-7) induced increases in sodium and water excretion in rats receiving either a low or normal sodium diet were and blocked in the presence of the AT 1 receptor antagonist (Losartan) in the presence of the, 'Mas' receptor antagonist (A-779). These data suggest that both AT1 and 'Mas' receptors need to be functional in order to fully mediate the renal responses to intra-renal Ang (1-7) infusion. Importantly, further experimentation also revealed that there is a proportional relationship between AT 1 receptor expression in the rat renal cortex and the magnitude of the excretory actions of intra renal Ang (1-7) infusion, which is only partially dependent on the level of 'Mas' receptor expression. These observations suggest that although Ang (1-7) induced increases in sodium and water excretion are mediated by the Mas receptor, the magnitude of these excretory responses appear to be dependent upon the level of AT 1 receptor expression and more specifically Ang II/ AT 1 receptor signalling. Thus in rats receiving a low sodium diet, Ang (1-7) acts via the Mas receptor to inhibit Ang II/ AT 1 receptor signalling. In rats receiving a high sodium diet the down regulated AT 1 receptor expression implies a reduction in Ang II/ AT 1 receptor signalling which renders the counter-regulatory effects of intra-renal Ang (1-7) infusion redundant.

Das Bistum Würzburg 7. Die Würzburger Bischöfe von 1617 bis 1684

Winfried Romberg führt mit dem Band Die Würzburger Bischöfe von 1617 bis 1684 die Bischofsreihe fort, die Alfred Wendehorst begonnen hat (Germania Sacra Neue Folge 1/4/13). Damit erscheint ein Band, der in besonderer Weise für den Schwerpunkt der Dritten Folge der Germania Sacra steht: Die Darstellung von Diözesen und Domkapiteln der Kirche des Alten Reiches. Er beleuchtet die Lebensläufe und Amtstätigkeiten neuzeitlicher Würzburger Bischöfe des 17. Jahrhunderts und umfasst die Pontifikate von Johann Gottfried I. von Aschhausen (1617–1622) bis zum Pontifikat von Konrad Wilhelm von Wernau (1683–1684). Die Bischöfe dieser Zeit waren von überregionaler Bedeutung und Wirksamkeit, wie sich beispielhaft in der Person des Bischofs Johann Philipp I. von Schönborn (1642–1673) zeigt, der zugleich Erzbischof von Mainz war. Johann Gottfried I. von Aschhausen, Franz von Hatzfeld und Peter Philipp von Dernbach waren Bischöfe von Würzburg und Bamberg in Personalunion, womit sich der Band auch an die Darstellung der Bamberger Bischofsreihe von 1522 bis 1693 von Dieter J. Weiß (Germania Sacra Neue Folge 38) anschließt. Die Viten, die das Wirken des einzelnen Bischofs in seinem Amt in den Vordergrund stellen, bewegen sich im geschichtsträchtigen Umfeld von Rekatholisierung, Dreißigjährigem Krieg und Frühabsolutismus.
