可的松主要用于腎上腺皮質(zhì)功能減退癥的替代治療,但現(xiàn)在氫化可的松已優(yōu)先用于此癥。因為可的松本身無活性,必需先在肝內(nèi)轉(zhuǎn)化成氫化可的松,某些肝臟疾病將影響其作用的可靠性。
Cortisone是一種孕烷甾類激素,是身體應(yīng)對壓力應(yīng)激時釋放的主要物質(zhì)。它能抑制免疫系統(tǒng),從而減少炎癥反應(yīng)和炎性疼痛、傷處腫脹。
Human Endogenous Metabolite
|
Cortisone (2.8-28,000 nM) dose-dependently attenuates the apoptosis induced by Cortisol in peripheral-blood mononuclear cells (PBMCs).
Cortisone (2 mg/kg; i.m. on alternate days for 2 months) decreases the BCG (the vaccine strain of tubercle bacillus) lesions and tuberculin reactions in rabbits.
Animal Model: | Male New Zealand white rabbits (2.1-2.4 kg) were injected with BCG at six days after the first administrtion |
Dosage: | 2 mg/kg |
Administration: | Intramuscular injection on alternate days for 2 months |
Result: |
Reduced the BCG lesions and tuberculin reactions.
Reduced the number of infiltrating mononuclear cells (MN), the amount of caseous necrosis and ulceration, and the percent of NM that were beta-galactosidase-positive. |
