There were fewer cases of gastrointestinal adverse events in the treatment group than in the control group (3 vs. 11 cases; χ2=4.565, P<0.05) and the number of abnormal liver function (2 vs. 9 cases; χ2=4.007, P<0.05).@*Conclusions@#Compound herba houttuyniae mixture combined with azithromycin could improve the clinical symptoms and signs, and shorten the symptoms duration and reduce the side reaction.
ABSTRACT
Objective To observe the bacteriostasis of herba houttuyniae liquid in bladder irrigation for treatment of rabbit bladder infection model, and to offer a new way for prevention and treatment of urinary tract infection.Methods Twenty male New Zealand long-eared white rabbits were divided into gentamicin control group and three different concentrations herba houttuyniae groups according to random number table method, each group 5 rabbits. The rabbit bladder infection model was replicated by injecting coli liquid 1 mL (105 cfu/mL) into the urinary bladder through a urethral catheter, and clipping the catheter for 1 hour. After model establishment for 3 days, in the three herba houttuyniae groups, 0.25, 0.50, 1.00 g/mL herba houttuyniae liquid 50 mL were injected into the bladder respectively, and in the gentamicin control group, 160 kU gentamicin was injected into the bladder. Before molding and after molding for 3, 5, 7, 9 days, ear blood in rabbit was taken, and white blood cell (WBC) count and neutrophil percentage (N%) were tested; at the same time, the middle segment morning urine was taken to detect bacteriuria and urine WBC positive rates; after the experiment, the animals were sacrificed, the urinary bladder tissues were taken, and the pathological changes in urinary bladder tissue were observed by a light microscope.Results Before molding, the bacteriuria in animals of each group was negative and the results of urine WBC, blood WBC and N% were within normal range. After molding for 3 days, bacteriuria and urine WBC positive rates reached 100%; with the prolongation of treatment after molding, the above two rates in each group were gradually decreased, and herba houttuyniae 0.50 g/mL and 1.00 g/mL groups appeared statistical significance on the 5th day (bacteriuria positive rate was 60% and 40%, urine WBC positive rate was 60% and 40% respectively, while the gentamicin control group and herba houttuyniae 0.25 g/mL group was still 100% positive, allP < 0.01); on the 9th day, the bacteriuria positive rate in both higher dosage herba houttuyniae groups was 0, in 0.25 g/mL group, it still had the positive rate 20%, showing herba houttuyniae 0.50 g/mL and 1.00 g/mL had stronger inhibitory effect than herba houttuyniae 0.25 g/mL. WBC and N% were increased in each group after molding, and on the 3rd day, WBC and N were significantly higher in each group than those before molding [WBC (×109/L): gentamicin control group 13.00±5.23 vs. 8.95±2.69, herba houttuyniae 0.25 g/mL group 14.52±10.28 vs. 8.73±3.16, herba houttuyniae 0.50 g/mL group 12.97±11.33 vs. 7.83±4.51, herba houttuyniae 1.00 g/mL group 13.03±9.17 vs. 6.45±3.85. N%: gentamicin control group 80.99±14.93 vs. 63.41±7.96, herba houttuyniae 0.25 g/mL group 89.62±9.41 vs. 70.01±9.13, herba houttuyniae 0.50 g/mL group 87.69±11.34 vs. 67.75±8.91, herba houttuyniae 1.00 g/mL group 85.67±12.81 vs. 65.12±4.63]. On the 7th day, WBC and N% fell, and on the 9th day, the WBC and N% were restored to normal range in herba houttuyniae 0.50 g/mL and 1.00 g/mL groups [WBC (×109/L): herba houttuyniae 0.50 g/mL group 8.56±5.38, herba houttuyniae 1.00 g/mL group 7.93±4.82. N%: herba houttuyniae 0.50 g/mL group 65.97±8.35, herba houttuyniae 1.00 g/mL group 65.57±9.12]. Under light microscopy, it was shown that the morphological appearances of tissue cells in various layers of bladder mucosa were normal in herba houttuyniae group, demonstrating that herba houttuyniae fluid in bladder did not cause allergic inflammatory reaction, etc.Conclusion The bacteriostatic action of herba houttuyniae liquid for bladder irrigation in treatment of rabbits with urinary tract infection is better than that of gentamicin.

ABSTRACT
Objective To investigate the synergic bactericidal activity of Herba Houttuyniae combined with levofloxacin on the biological envelope of mucoid Pseudomonas aeruginosa(PA).Methods MIC (minimal inhibitory concentration) was determined by using tube doubling dilution method. In-vitro biological envelope models of PA were established by plate cultivation method. The bacterial colony were counted by MTT method. The morphology of biological envelope were observed under scanning electronic microscope (SEM) .Results On the 7th day of cultivation,the stable biological envelope formed.Herba Houttuyniae or levofloxacin alone had no effect on the biological envelope or the number of surviving bacterial colony. The combination of the above two could destroy the structure of biological envelope and decrease the number of surviving bacterial colony.Conclusion Herba Houttuyniae combined with levofloxacin has synergistic germicidal actions on biological envelope of PA.

ABSTRACT
AIM: To compare the effects of Yuxingcao(Herba houttuyniae),Paojiang(Radix aconiti lateralis praeparata) and Fuzi(Rhizoma Zingiberis recens(blastfried)) on ventricular remodeling induced by high pressure in rats. METHODS: Ventricular remodeling model was induced by constriction of abdominal aorta in rats.After 1 week,the model rats were divided randomly into 5 groups,such as model control,captopril,Yuxingcao,Paojiang and Fuzi.In addition,a sham-operated group was designed.The rats were given per oral captopril,Yuxingcao,Paojiang and Fuzi respectively for consecutive 3 weeks.Rats in sham-operated group and model control group were treated with distilled water.The blood pressure was measured.The ratio of LVW/BW,HW/BW was calculated as an index indicating the grade of ventricular hypertrophy.The contents of AngⅡ,ET in heart tissue and blood level of aldosterone(ALD) were determined by radio-immunoassay.The myocardium collagen volume fraction(CVF),perivascular circumferential area(PVCA) and the content of type Ⅰ and Ⅲ collagen were determined by histological assay using the picric acid/sirius red stain.The expression of protein kinase C(PKC) was determined by immunohistochemical analysis. RESULTS: Yuxingcao could lower the blood pressure and the ratio of LVW/BW,HW/BW;reduce the level of AngⅡ,ET in myocardium and ALD in blood serum,decrease myocardium CVF,PVCA and the content of type Ⅰ,Ⅲ collagen,and inhibit the expression of PKC.Paojiang did not show obvious effects mentioned above,neither did Fuzi,except that it decreased the level of AngⅡ in myocardium. CONCLUSION: Yuxingcao,the herb with cool nature,can attenuate the ventricular remodeling,and inhibit the over-activity of neuroendocrine factor release.Paojiang and Fuzi,the herbs with hot nature,fail to show that.
ABSTRACT
AIM: To observe the effects of herba houttuyniae injection, a chinese medicine, on myocardial injury induced by endotoxin and to explore the possible mechanism. METHODS: 24 male SD rats,weghting (250?30) g, were randomly divided into three groups: normal control group(NC, n=6), endotoxin group (ET, n=6), herba houttuyniae injection puls endotoxin group (HHI+ET, n=6) and herba houttuyniae injection group (HHI, n=6). Heart was isolated from rats and perfused on Langendorff apparatus with Krebs-Henseleit (KH) buffer (Saturation 95%+5%CO_2) at a constant pressure (8.33 kPa) and temperture(37℃). The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) content of efflux from coronary artery were measured at certain time points (0 min, 20 min, 50 min, 80 min). The ventricular function, the concentration of nitric oxide (NO) and the activity of succinate dehydrogenase (SDH) in myocardial tissue were also observed. RESULTS: Compared with ET group, the percentage recovery of the product of left ventricular pressure difference and heart rate [(LVSP-LVEDP)?HR], LVDP,+dp/dt_(max) were all increased apparently in HHI treatment group. The activities of SOD, SDH and the concentration of MDA, NO in HHI treatment group were close to that in normal control group. CONCLUSION: Herba houttuyniae injection protects myocardium against injury induced by endotoxin. It may be related to decrease in the level of NO, the strength of antioxidation, the stability of enzyme activities and the improvement of energy metabolism in myocardium.
