AIM: To investigate the effect of interleukin-2 (IL-2) on the intracellular calcium in electrically stimulated adult rat ventricular myocytes during anoxia and reoxygenation. METHODS: The isolated cardiac ventricular myocytes were exposed to 5 min anoxia followed by 10 min reoxygenation. Chemical anoxia was introduced by Krebs-Henseleit (K-H) solution containing 10 -3 mol/L sodium dithionite. The spectrofluorometric method was used to verify intracellular calcium transient with fura-2/AM as calcium fluorescence probe. RESULTS: It was shown that during anoxia, the amplitude of Ca 2+ transient was decreased, diastolic [Ca 2+ ] i, time to peak and time to relaxation of Ca 2+ transient were increased. All the parameters were got back but did not returned to the pre-anoxia level during reoxygenation. IL-2 at 2?10 5 U/L administrated during anoxia aggravated the effect of rexoxygenation on [Ca 2+ ] i transient. Pretreatment with a specific ? opioid antagonist, nor-BNI (10 -8 mol/L), abolished the effect induced by IL-2 during anoxia on the [Ca 2+ ] i transients, whereas specific ? opioid antagonist, naltrindole (10 -6 mol/L), did not cancel the effect. CONCLUSION: It is concluded that administration of IL-2 during anoxia aggravated the effect of reoxygenation on the [Ca 2+ ] i transients of isolated ventricular myocytes, which was mediated by cardiac ? opioid receptor pathway.

Objective To investigate the effect of Shenmai injection in treating elderly with orthostatic hypotension. Methods The total of 97 cases of patients with orthostatic hypotension were randomly divided into 2 groups, which was injected intravenously with 100 mL Shenmai injection once daily as the treatment group, with 100 mL glucose as the control.The treatment lasted 14 days. The clinical symptom score, the difference of blood pressure, the P￣selectin, and the platelet maximum aggregation were measured. Results Compared with the control, Shenmai injection significantly reduced the clinical symptom scores of patients (P<0.05), lowered the difference of blood pressure for upright and supine significantly (P<0.05), decreased the platelet maximum aggregation and P￣selectin remarkably (P<0.05). Conclusion Shenmai injection significantly reduces the difference of blood pressure for upright and supine of the elderly with orthostatic hypotension, and inhibits the activities of platelets, thus improves the clinical symptoms.

AIM: To study the effect of salvia miltiorrhiza (SM) on cell contraction and intracellular calcium of enzymatically isolated rat ventricular myocytes during normoxia and anoxia/reoxygenation. METHODS: Contraction and intracellular calcium were determined with video tracking system and spectrofluorometric method, and the chemical anoxic method was employed. RESULTS: The ?d L /d t max , dL of cell contraction and the amplitude of [Ca 2+ ] i in the cardiomyocytes following SM treatment were decreased in a dose-dependent manner. During anoxia, the ?d L /d t max , dL and amplitude of [Ca 2+ ] i were decreased, while the diastolic Ca 2+ level was elevated compared with control group. All the contractile parameters and the diastolic Ca 2+ level were back toward pretreatment values during reoxygenation, but could not return to control level. After the treatment with SM (3 g/L), ?d L /d t max and dL of cell contraction and the amplitude of [Ca 2+ ] i were higher and the diastolic Ca 2+ level was lower than those in anoxia/reoxygenation group. CONCLUSION: SM antagonized effects of anoxia and reoxygenation on cell contraction and intracellular calcium in isolated ventricular myocytes.

AIM: We examined the effect of interleukin- 2 (IL-2) on calcium handlin g of rat cardiomyocytes. METHODS: The effects of steady state an d transient chan ges in stimulus frequency on the intracellular calcium transient were investigat ed in the isolated ventricular myocytes with spectrofluorometry technique. RESULTS: Under the steady state (0.2 Hz), IL-2 at 2?10 5 U/L decr eased the peak [Ca 2+ ] i and amplitude of the [Ca 2+ ] i transient, increas ed the diastolic calcium level, and prolonged the decay of the calcium transient . At 1.25 mmol/L of extracellular [Ca 2+ ], when increasing the stimulus frequency from 0.2 to 1.0 Hz, diastolic calcium level and peak [Ca 2+ ] i as well as the amplitude of the transient were inc reased. The positive frequency relationship was blunted in the IL-2-treated myoc ytes and this was not normalized by increasing extracellular [Ca 2+ ] t o 2.5 mmol/L . The caffeine induced Ca 2+ release was increased with increase in stimu lus freq uency. IL-2 inhibited the frequency relationship of caffeine induced Ca 2+ releas e. The restitution was not different between control and IL-2 groups at the 1.25 mmol/L of extracellular [Ca 2+ ], which was slowed in IL-2-treated myo cytes when t he extracellular [Ca 2+ ] was increased to 2.5 mmol/L. CONCLUSIO NS: It is concluded that the blunted frequency response of IL-2-treated myocytes was resulted from the decrease in SR Ca 2+ release, which was related to depression of SR funct ion. Despite the evidence of depressed SR Ca 2+ uptake, the restitution o f ca lcium transient at 1.25 mmol/L of extracellular [Ca 2+ ] remains uncha nged, which maybe due to the increase in the Na +/Ca 2+ exchanger activi ty.
