Anidulafungin dosing in critically ill patients with continuous venovenous haemodiafiltration.

Background: Anidulafungin is indicated as a first-line treatment for invasive candidiasis in critically ill patients. In the intensive care unit, sepsis is the main cause of acute renal failure, and treatment with continuous renal replacement therapy (CRRT) has increased in recent years. Antimicrobial pharmacokinetics is affected by CRRT, but few studies have addressed the optimal dosage for anidulafungin during CRRT.

Chronic administration of clomipramine prevents the increase in serotonin and noradrenaline induced by chronic stress.

The effects of chronic clomipramine administration (15 mg/kg daily for 23 days) on changes in serotonin (5-hydroxytryptamine, 5-HT), 5-hydroxyindoleacetic acid (5-HIAA) and noradrenaline (NA) induced by chronic stress have been studied in the rat brain. Chronic stress increased 5-HT in midbrain, pons and hippocampus, 5-HIAA in frontal cortex, midbrain, pons and hippocampus, and NA in midbrain and striatum. Chronic clomipramine significantly decreased the levels of 5-HT in most regions.

Chronic stress increases serotonin and noradrenaline in rat brain and sensitizes their responses to a further acute stress.

The effects of 1 h/day restraint in plastic tubes for 24 days on the levels of serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), tryptophan (TP), and noradrenaline (NA) in six regions of rat brain 20 h after the last restraint period were investigated. The levels of 5-HT, 5-HIAA, and NA but not TP increased in several regions. The effects of 1 h of immobilization on both control and chronically restrained rats were also studied.

Previous chronic chlorimipramine treatment did not modify some physiological responses to acute and chronic stress in rats.

The effects of previous chronic administration of the tricyclic antidepressant drug chlorimipramine (CMI) on some physiological responses of adult male rats to stress has been studied. CMI significantly reduced food intake and body weight gain, but did not alter either adrenal weight or basal serum corticosterone levels. Corticosterone response to 1 h of immobilization stress was the same in saline and CMI-treated rats.

Crowding-induced changes in basal and stress levels of thyrotropin and somatotropin in male rats.

The effects of crowding on thyrotropin (TSH) and somatotropin (GH) secretion were studied in two-month-old male rats. Crowded rats (9-10 per cage) showed lower serum GH levels than controls (3 per cage). Likewise, serum GH was lower in crowded rats after acute exposure to stress.
