Objective: To compare hemodynamic effects of infusion of diethylamine/nitric oxide (DEA/NO)and sodium nitroprusside(SNP)during controlled hypotension. Method: General anesthesia was induced in dogs. The twelve healthy adult dogs were randomly assigned into one of two groups. 0.00l% DEA/NO or 0.01% SNP was infused to induce mean arterial pressure(MAP) to decrease to 60% of baseline and be maintained for 30 min. During hypotension, MAP,central venous pressure (CVP), mean pulmonary artery pressure (MPAP)and cardiac output (CO) were measured and recorded. Arterial blood gas, blood lactate and urine output were also measured. Result: HR,CVP and CO were unchanged during hypotension period in both groups, MPAP decreased correspondently with MAP. There were no significantly changes in arterial blood gas,blood lactate and urine output in both groups during hypotension. Conclusion: Controlled hypotension achieved with infusion of DEA/NO has a rapid onset and short duration of action.The hemodynamics were similar to those of SNP.

Mycelial morphology are exploited a great influnence to the metabolites of fungi. The effect of the mycelial morphology on producing lycopene by Blakeslea tripora was investigated. The results indicated that pellets has little role on fermentation when adding kerosene and triton-x100, However, The content of lycopene in the medium reached to 98.6mg/L by adding Ig/L span-20, forming dispersed mycelia, which is 3 times of the control experiments.

OBJECTIVETo investigate the protective effect of tanshinone II A on porcine aortic endothelial cells (PAEC).
METHODSPAEC were stimulated with angiotensin II (Ang- II) for different acting time (1 h, 6 h and 24 h) and Tanshinone II A was added along with Ang- II stimulation (Group A) or 6 h after it (Group B). The nitric oxide (NO) level, the protein and mRNA expression of nitric oxide synthase (cNOS) in PAEC were measured by nitric acid deoxidizing assay, RT-PCR and immunohistochemical assay, respectively.
RESULTSWith the prolongation of acting time of Ang- II, the level of NO and eNOS expression in PAEC sequentially decreased in a negative acting time dependent manner (P < 0.01), which could be inhibited by tanshinone II A treatment independent to the dosage used (P< 0.01). The inhibitory effect of tanshinone II A was better in Group A than that in Group B either at 1 h or at 6 h after treatment (P<0.05). However, 24 h later, no significant difference was found between the effect in the two groups (P >0.05).
CONCLUSIONTanshinone II A could inhibit the negative effect of Ang- II on NO production and eNOS expression in PAEC.

OBJECTIVETo explore the molecular biological mechanism for tanshinone II A reversing left ventricular hypertrophy, it would be studying the effect of tashinone on the endothelial nitric oxide synthase (eNOS) and protein kinase C (PKC) in the hypertrophic cadiocyte of rats suffered abdominal aorta constriction.
METHODSD rats were operated with abdominal aorta constriction and 8 rats were done with sham surgery. After 4 weeks, all rats were divided into 4 groups: myocardial hypertrophy group, low dose tanshinone II A group (10 mg x kg(-1) x d(-1)), high dose tanshinone II A group (20 mg x kg(-1) x d(-1)) and valsartan group (10 mg x kg(-1) d(-1) intragastric administration). 8 weeks later, the rats were used to measure the left ventricular mass index (LVMI) with the tissue of left ventricle and myocardial fiber dimension (MFD) by pathological section and HE stain, to detect the nitric oxide content by nitrate reductase, to detect the genic expression of eNOS by RT-PCR and to detect the activity of protein kinase C (PKC) by Western blotting.
RESULT1) The blood pressure in group myocardial hypertrophy [(186 +/- 13) mmHg] and tansginone II A [low and high dose (188 +/- 11,187 +/- 14) mmHg] was obviously higher than that in group sham surgery and valsartan group [vs (117 +/- 8, 136 +/- 15) mmHg, P < 0.01]. But there was no difference between group myocardial hypertrophy and group tanshinone II A (low and high dose). 2) The LVMI and MFD were obviously higher in group tanshinone II A low and high dose) and group valsartan than those in group sham surgery (P < 0.05), and lower than those in group myocardial hypertrophy (P < 0.01). 3) The NO level was obviously higher in group tanshinone II A (low and high dose) and group valsartan than that in group myocardial hypertrophy (12.78 +/- 1.66, 11.95 +/- 1.39, 12.26 +/- 2.08 vs 5.83 +/- 1.06) micromol x L(-1), (P < 0.01 ), and lower than that in group sham surgery (vs 19.35 +/- 1.47) micromol x L(-1), (P < 0.05). 4) The expressive level of eNOS mRNA and protein in myocardial hypertrophy group was less than that in other groups (P < 0.01). And valsartan group was less than tanshinone II A groups and sham surgery group (P < 0.05), but there were no difference among the two tanshinone II A groups and sham surgery group. 5) The level of PKC protein in group myocardial hypertrophy was obviously higher than that in all the other groups (1.291 +/- 0.117 vs 0.563 +/- 0.094, 0.605 +/- 0.051, 0.519 +/- 0.062, 0.827 +/- 0.086, P < 0.01), and the level in group valsartan was higher than that in group sham operation and group tanshinone II A (low and high dose).
CONCLUSIONNO/NOS system in local myocardium has close relationship with the pathological process for myocardial hypertrophy. Tanshinone II A can produce the pharmacological action to reverse myocardial hypertrophy by inhibiting the activity of PKC and promoting the genic expression of eNOS in local myocardium and the production of endogenous NO.

OBJECTIVETo observe effects of removing arms and ovarian on lumbar intervertebral disc and vertebral bone mineral density (BMD) by establishing rat model of lumbar intervetebral disc degeneration (IDD) with kidney deficiency, and to explore internal mechanism of disc degeneration, relationship between disc degeneration and osteoporosis.
METHODSThirty Sprague-Dawley female rats aged one month were randomly divided into control group, lumbar IDD group and lumbar IDD with kidney deficiency group (combined group), 10 rats in each group. Lumbar IDD group removed double arms, lumbar IDD with kidney deficiency group removed double arms after 3 months, both ovaries were removed. Vertebral bone mineral density were observed by Micro-CT scan; morphological changes were tested by safranine O-fast green staining; II, X collagen protein expression in the intervertebral disc were obsevered by immunohistochemistry; extracellular matrix gene expression were obsevered by real-time polymerase chain reaction (RT-PCR), in order to evaluate the effects of removed of forelimbs and double ovarian on degeneration and vertebral bone mineral density of intervertebral disc.
RESULTSMicro-CT scan showed osteoporosis in kidney deficiency group was obviously worse than other two groups; safranine O-fast green staining showed that intervertebral space became narrowed, intervertebral disc tissue degenerated obviously, chondral palte was underdeveloped in kidney deficiency group; immunohistochemistry showed that X collagen expression increased, type II collagen expression decreased in kidney deficiency group; RT-PCR showed that type II collagen expression in lumbar IDD group and kidney deficiency group was lower than control group, and had statistical meaning among three groups (P=0.000, P=0.000); Age 1 in lumbar IDD group and kidney deficiency group was lower than control group, and had statistical meaning among three groups (P=0.000, P= 0.000); while type X collagen expression was higher than control group, but no significant meaning; MMP-13 in lumbar IDD group and kidney deficiency group was higher than control group, with significant meaning compared among three groups (P= 0.000, P=0.000); aggrecanase-2 in lumbar IDD group and kidney deficiency group was higher than control group, with significant meaning compared among three groups (P=0.006, P=0.008).
CONCLUSIONRats model of lumbar disc degeneration established by removed forelimbs and ovariectomized can occure "bone like"--osteoporosis, which is similar with clinical kidney lumbar disc degeneration in tissue morphology, molecular cell biology expression.
