Ringed sideroblasts were studied by means of transmission electron microscopy in patients suffering from refractory anaemia with ringed sideroblasts (RARS) of myelodysplastic syndrome (MDS) to provide more information on the structural organization of nucleoli in these abnormal erythroblasts. For control of the electron microscopic observations nucleoli in erythroblasts were also visualized by two widely used cytochemical procedures for the demonstration of RNA and AgNOR proteins. In contrast to previously described ultrastructure of nucleoli in "normal" erythroblasts, nucleoli of ringed erythroblasts in RARS of MDS were frequently characterized by a reduced incidence or lack of dense ribonucleic acid (RNA) containing granular components...

The anti-fertility, anti-implantation, and ovarian histological alterations of the ethanolic extract of Ferula hormonis have been investigated in female mice. The intragastric application of 3 mg/kg per day of such extract for 6 weeks resulted in a significant reduction in female mice fertility. Furthermore, it caused a decrease in the number of mated females, the total number of implantations, and the number of viable fetuses. These changes were also associated with ovarian atrophy and a concomitant increase in the connective tissue...

The effects of an aqueous extract of Ferula hormonis on social aggression, fertility and some physiological and biochemical parameters were investigated in male mice. The ingestion of 3 mg/kg of aqueous extract of F. hormonis for six weeks clearly inhibited social aggression. Body wet weight and other sex accessory organ weights were significantly reduced by this treatment. The ingestion of this extract by male mice resulted in a significant reduction of their fertility. This treatment caused a significant decrease in the number of pregnant females, number of implantations and viable fetuses in females impregnated by males that ingested this extract...

The authors review the literature regarding the animal models of osteoporosis in two main groups: The resorption-dominant models (oovariectomy, orchiectomy, limbs imobilization, calcium restriction and use of hormonies) and another group, the formation-deficit models (senil rats, SAM mouse, glucocorticoid administration or limbs imobilization.

A review of the historical development of conservative and liberal through reveals contradictory basic assumptions: the former views man as essentially evil by nature, and places its priorities upon self-restraint; the latter views man as essentially good, and with umlimited capabilities, and celebrates his efforts at creating a perfect society for himself. Three clinical vignettes are recounted in which the patient's intrapyschic organization found support from a hormonious political philosophy. It is suggested that conservatism and liberalism offer the individual an ideological resolution to the narcissistic injuries he experiences as a consequence of life's inevitable and developmentally determined disappointments...

The authors studied the excretion of catecholamines in the diurnal urine in patients with sacrolumbar and cervicothoracal radiculitis in the acute stage with pain and the changes of excretion under the influence of physiotherapy. In radiculities with the pain syndrome there was an activation of catecholamine systems, mainly in the hormonial link of the sympathico-adrenal system. Following treatment along with the disappearance of the pain syndrome there is a normalization of the excretion of adrenalin, noradrenalin and the terminal product of inactivated catecholamine in the diurnal urine...
