This study is to investigate if madecassoside can protect against myocardial reperfusion injury in rabbit heart in vivo. The ischemia reperfusion model was established. Left ventricular function and ECG were monitored at the ischemia and reperfusion period. The infarct areas were expressed as percentage. The levels of LDH, CK, MDA and SOD were measured and C-reactive protein (CRP) in serum was measured by ELISA kit. Cardiomyocyte apoptosis were measured by TUNEL staining. A monoclonal rabbit anti-goat Bcl-2 proteins as primary antibody was used for Bcl-2 immunohistochemical staining. Treatment with madecassoside (3.2, 1.6 and 0.8 mg x kg(-1)) i.v. during ischemia reperfusion injury attenuated myocardial damage, that is, characteristic of decreasing infarct size, decreasing LDH and CK release. Activities of SOD were diminished and MDA level increased obviously in control group whereas pretreatment with madecassoside significantly blunted the decrease of SOD activity, markedly reduced the levels of MDA, CRP and cardiomyocyte apoptosis, and upregulated the expression of Bcl-2. Madecassoside has the protective effect against myocardial ischemia reperfusion injury, and effects of anti-lipid peroxidation, enhancement of SOD activity, anti-inflammation and anti-apoptosis.

Objective To evaluate calcium deficiency and demand in pre-puberty twins and to analyze the heritability of serum bone alkaline phosphatase(BALP).Methods A total of 73 pairs of twins aged 9-16 years were examined by BALP test.Microsatellite polymorphism Was used To diagnose the zygosity of twins,while both intraclass correlation coefficient method and Christian formula were perfortled to investigate heritability of serum BALP.Results The results of zygosity diagnosis displayed that 34 pairs of twins were monozygotic(MZ)twins and 39 pairs were dizygotic(DZ)twins.97.9%of the subjects appeared unusual in the activity of BALP,with activity of BALP>250 U/L in 43.1%of subjects and 200-250 U/L in 54.8%of the subjects.The intake of calcium Was unsatisfied in 48.4%of the boys and 39.0%in girls.Less than 10.0% of the Sllbiects were satisfied with the intake of calcium in each age group while over 45.0%of the snbjects in 10-13 age group were deficient in calcium.Differences between the means of BALP in different sex groups(t=1.633,P=0.105)and different age groups(F=0.323,P=0.924)were not statistically significant.Heritability analysis displayed that intra-class variation.Inter-class variation.Intra-class correlation coefficient were 191.54,1462.22,0.77 in MZ twins,and those were 491.03,1475.57,0.50 in DZ twins respectively with the heritability of BALP activity as 0.54.Conclusion Calcium deficiency Is commonplace in pre-puberty twins.Our data showed that the BALP activity was influenced both by genetic(54%)and environmental(46%)factors.

Objective To study the effects of insulin therapy on alterations of learning and memory functions and somatostatin (SS) and vasoactive intestinal peptide (VIP) levels in frontal cortex and hippocampus of diabetic rats. Methods The diabetic rat models were produced by injection with 1% streptozotocin, followed by insulin administration. The water maze test was used to verify the changes of learning and memory functions of the rats and radioimmunoassary was carried out to observe the alterations of SS and VIP levels in the cerebral cotex and hippocampus. Results The swimming time of untreated diabetic rats in water maze was prolonged significantly and the successful frequencies decreased significantly in comparison to those of controls. The contents of SS reduced significantly both in the frontal cortex and hippocampus of untreated diabetic rats, while VIP were not changed. The changes in learning and memory functions and SS levels in insulin-treated diabetics were not significantly different from those of controls. Conclusion The cognitive dysfunctions induced by diabetes may be correlated with the decrease of SS and alleviated with insulin administration.

AIMTo study the preparation of hydroxypropyl methylcellulose phthalate (HPMCP) nanoparticles and compare its pharmacokinetic characteristics with Neoral.
METHODSHPMCP nanoparticles loaded cyclosporine A were prepared by solvent-nonsolvent method. CyA-HP50 nanoparticles, CyA-HP55 nanoparticles and Neoral were orally administered at the dosage of 15 mg x kg(-1) to rats. The CyA concentration in blood were determined by HPLC. Pharmacokinetic parameters were calculated by 3P97 program.
RESULTSThe concentration-time data of the three preparations were best fit by two compartment model. The relative bioavailability of CyA-HP50 and CyA-HP55 nanoparticles calculated by the AUC0-72 were 82.3% and 119.6%, bioequivalent to the reference of Neoral. The relative bioavailability of CyA-HP55 nanoparticles was 145.3% of CyA-HP50 nanoparticles.
CONCLUSIONCyA HPMCP nanoparticles could be prepared easily and reproducibly. It was found that the oral absorption of CyA can be increased by using the HPMCP nanoparticles.

OBJECTIVETo investigate the effects of ursolic acid (UA) on T-cell proliferation and activation, as well as to examine its effect on nuclear factor-κB (NF-κB) signaling pathway in T cells.
METHODST-cells isolated from BALB/c mice were incubated with UA at concentrations ranging from 5-30 μmol/L in the presence of phorbol 12-myristate 13-acetate (PMA) or PMA plus ionomycin. The proliferation of T cells was measured by the MTT assay. The expressions of CD69, CD25, and CD71 on T-cell surface were analyzed using flow cytometry. The level of interleukin-2 (IL-2) in the culture supernatant of activated T cells was quantified by enzyme-linked immunosorbent assay (ELISA). The level of phosphorylated IκB-α (p-IκB-α) in total protein and p65, a subunit of NF-κB, nuclear translocation were measured by Western blot analysis.
RESULTSUA in a dose-dependent manner significantly decreased the proliferation and inhibited the surface expressions of CD69, CD25, and CD71 in murine T lymphocytes upon in vitro activation (P<0.01). Significant reduction of IL-2 production was found in activated T cells treated with UA (P<0.01). The PMA-induced increase in p-IκB-α protein was inhibited, and nuclear translocation of p65 from the cytoplasm was blocked by UA.
CONCLUSIONUA is a potent inhibitor for T cell activation and proliferation; these effects are associated with the inhibition of NF-κB signaling pathway.
