Capillary Resistance and Hematological Responses of Normal and Stressed Animals to Cortisone
Almost nothing in the living organism is constant, but rather coordinated physiological processes attempt to create a balance between the various systems. The great French physiologist Claude Bernard (1) wrote, "It is the fixity of the milieu interieur which is the condition of free and independent …

The Effect of Reticulo-Endothelial Blockade on the Capillary Resistance Responses to Cortisone and Sth
… on the effect of the R.E. system on ACTE and cortisone activity, it was decided to attempt to resolve this controversy. Instead of using eosinophile counts as an index of corticois activity, capillary resistance was employed. This is justified by the work of Kramer and his associates (12,15) …

LC-ESI-MS/MS quantification of hair cortisol, cortisone and DHEA in combined oral contraceptive users
… reflection of total cortisol exposure, cortisone, the inactive form of cortisol was quantified as well. Dehydroepiandrosterone (DHEA), a hormone that has anti-cortisol activity, was also intended to be added to reflect total cortisol exposure. An in-house LC-ESI-MS/MS method was …

The metabolism of cortisol in the human feto-placental unit
A method for assaying cortisol and cortisone using chromatography on either Paper or Sephadex LH-20 columns, followed by competitive protein binding, has been applied to umbilical cord and maternal plasma samples. In mixed cord plasma the mean cortisol concentration was 6.0 ± 0.8 µg/100 ml (n = 9) …

THE DOUBLE BOND IN Δ1-2 POSITION OF STEROIDS: A MATTER OF CONTROVERSY IN THE CONTROL OF ILLICIT TREATMENTS OF FARM ANIMALS
… a possible transformation of cortisol and cortisone into prednisolone and prednisone in cattle faeces. The transformation of the II phase metabolite cortisol glucuronide was studied, too. The method consisted once more of incubation of bovine faecal matter suspended in 0.9% saline spiked …

Effects of augmentation agents on emotional memory consolidation and subliminal cue exposure to fear-relavent stimuli
… learning. Study 1 examined the effect of DCS and cortisone, another cognitive enhancer, on emotional memory consolidation in a nonclinical sample to investigate the effect of these augmentation agents on emotional recall. Men with no current psychological disorder participated in a two-day study …

Estrogen Regulation of the Pregnant Baboon Placental 11β-Hydroxysteroid Dehydrogenase (11β-HSD)-Catalyzed Metabolism of Cortisol and Cortisone and Its Effect on the Development of the Fetal Hypothalamic-Pituitary-Adrenal Axis
… metabolism of cortisol (F) and cortisone (E) from preferential reduction (E to F) at midgestation to oxidation (F to E) near term results in a decline of bioactive cortisol crossing the placenta and reaching the fetus culminating in activation of the hypothalamic-pituitary …

Structure-function analysis of 11β-hydroxysteroid dehydrogenase
… (11β-HSD1) is a key enzyme in the conversion of cortisone to the functional glucocorticoid hormone cortisol. This activation has been implicated in several human disorders, notably the metabolic syndrome where 11β-HSD1 has been identified as a novel target for potential therapeutic drugs. Crystal …

Determining the viability of breathwork and meditation as intervention techniques for stress in the forensic science community
… and stress responses. Salivary cortisol and cortisone measurements provided statistics to analyze hormonal changes in stress. Participants of the study were requested to partake in practicing cyclic physiological sighing and mindfulness meditation for 30 days, depending on their random …

Influence of Cellular Localization on Activity of Hydroxysteroid Dehydrogenases
… 11beta-HSD1, which catalyzes the reduction of cortisone to cortisol. Most mammalian cells supplied with adequate glucose and oxygen maintain cytoplasmic high nicotinamide concentration gradients, [NADPH] >> [NADP+] and [NAD+] >> [NADH], and in the strongly oxidizing environment of the ER lumen, …

Effect of 9 α-fluorohydrocortisone Acetate on Gastric and Salivary Electrolytes of Normal Fasting Subjects
… found a change in salivary electrolytes when cortisone, desoxycortisone, or ACTH were given to normal subjects. In these cases as in primary aldosteronism there was a decreased Na:K ratio and potassium excretion, with sodium retention. There were no reports in the reviewed literature which …

A Study of the Effects of Ovariectomy and Ovarian Hormone Replacement Therapy on Carbohydrate Metabolism in Mice
… the antagonism of insulin by growth hormone and cortisone was more severe. Insulin secretion in vitro was decreased, the total pancreatic and islet insulin content was reduced, and preliminary histological studies showed evidence of a reduction in β-cell numbers and some islet degeneration. …

A description of the pharmacokinetics of first line anti-tuberculosis drugs and adjunctive corticosteroid therapy in the pericardial compartment and their effect on cytokine profiles in the pericardial compartment of patients with tuberculous pericarditis
… of glucocorticoids, the pericardial cortisol/ cortisone ratio was twice that of plasma (p=0.0050). A similar elevation of the cortisol/ cortisone ratio at the site of infection has previously been described in the bronchial lavage fluid of patients with pulmonary tuberculosis. Among those …

Design of novel drug delivery system and optimal dosage regimens
… data from the administration of fentanyl. Cortisone concentrations through the patch and skin layers were predicted. The results were used to rank the relative impacts of the design parameters on the corticosterone delivery and to make proper suggestions for fabricating the products. …

The role of 11β-Hydroxysteroid Dehydrogenase type 1 and Hepatic Glucocorticoid Metabolism in the Metabolic Syndrome
… type 1 (11\(\beta\)-HSD1) which activates cortisone to cortisol in vivo. Through a series of in vitro and detailed translational studies, this thesis attempts to investigate hepatic glucocorticoid metabolism with relevance to the pathophysiology of the metabolic syndrome. The hepatic …
