RESUMO

The steroid receptor (SR) complex contains FKBP51 and FKBP52, which bind to tacrolimus (TAC) and cyclophilin 40, which, in turn, bind to cyclosporine (CYA); these influence the intranuclear mobility of steroid-SR complexes. Pharmacodynamic interactions are thought to exist between steroids and calcineurin inhibitors (CNIs) on the SR complex. We examined the effect of CNIs on steroid sensitivity. Methylprednisolone (MPSL) sensitivity was estimated as the concentration inhibiting mitosis in 50% (IC50) of peripheral blood mononuclear cells and as the area under the MPSL concentration-proliferation suppressive rate curves (CPS-AUC) in 30 healthy subjects. MPSL sensitivity was compared between the additive group (AG) as the MPSL sensitivity that was a result of addition of the proliferation suppressive rate of CNIs to that of MPSL and the mixed culture group (MCG) as MPSL sensitivity of mixed culture with both MPSL and CNIs in identical patients. IC50 values of MPSL and cortisol sensitivity were examined before and 2 months after CNI administration in 23 renal transplant recipients. IC50 and CPS-AUC values of MPSL were lower in the MCG than in the AG with administration of TAC and CYA. The CPS-AUC ratio of MCG and AG was lower in the TAC group. IC50 values of MPSL and cortisol tended to be lower after administration of TAC and CYA, and a significant difference was observed in the IC50 of cortisol after TAC administration. Steroid sensitivity increased with both TAC and CYA. Furthermore, TAC had a greater effect on increasing sensitivity. Thus, concomitant administration of CNIs and steroids can increase steroid sensitivity.

RESUMO

Pain and stress alleviation after acupuncture treatment was assessed in this study. Patients responded to a questionnaire designed to determine the amount of stress they were experiencing, and data were obtained for patient salivary amylase, cortisol, secretary IgA (s-IgA), and leptin receptor (OBRb). As a part of this study on acute pain, 6 factors were extracted from the questionnaire. The second factor (pain removal) was well correlated with salivary amylase activity in patients with cervico-omo-brachial syndrome. An evaluation of cumulative acupuncture treatments showed that salivary cortisol increased and s-IgA decreased. In addition, a decreased s-IgA level significantly correlated with chronic pain removal. The questionnaire correlated well with measurements of salivary markers suggesting that they can be taken as indices of therapeutic efficacy in acupuncture treatment.
