BACKGROUND AND PURPOSE: To evaluate the efficacy and the safety of WF10 as adjunct to standard treatment in the management of late hemorrhagic radiation cystitis compared to standard treatment alone. PATIENTS AND METHODS: Cervical cancer patients with Grade 2 or 3 late hemorrhagic radiation cystitis, were randomized and treated with WF10 0.5 ml/kg body weight, diluted in physiological saline or 5% dextrose water 250 ml, intravenous infusions over 2 h on 5 consecutive days, every 3 weeks for 2 cycles plus standard treatment (WF10 group) or standard treatment alone (control group). Fifty patients in each group were evaluated by questioning; urinalysis and cystoscopy during a 1 year follow up. RESULTS: At week 7, 37 patients (74%) in the WF10 group and 32 patients (64%) in the control group showed complete resolution in objective hematuria (P = 0.28). Significantly lower use of antibiotics (P = 0.002) and antispasmodics (P < 0.001) was found in the WF10 group. Among the responders, 24 patients (77%) in the control group experienced recurrent objective hematuria, whereas in the WF10 group only 17 patients (47%) experienced a recurrence (P = 0.01). Recurrence of objective hematuria occurred significantly faster in the control group as evidenced by Kaplan-Meier and log-rank statistics (P = 0.004), suggesting a long-term effect of WF10. Cystoscopy, at the end of the treatment period and after the one year follow up showed overall improvement without significant difference between two groups. No severe toxicity was monitored. CONCLUSIONS: WF10 therapy is a safe, non-invasive and convenient method in the management of late hemorrhagic radiation cystitis. WF10 therapy, as adjunct to standard treatment, has significantly reduced recurrence of objective hematuria, compared to standard treatment alone, during a one year follow up. 相似文献

We investigated the expression of parathyroid hormone-related peptide (PTHrP) and the relationship between PTHrP and its endoprotease furin in gastric cancer. PTHrP was colocalized with furin in 75% of gastric cancer tissues (six of eight) from patients with high serum PTHrP levels. PTHrP mRNA expression was confirmed in 67% of gastric cancer cell lines (four of six), whereas furin mRNA was detected in all six gastric cancer cell lines. In a cultured gastric cancer cell line, MKN28, mature PTHrP protein expression was markedly increased by transfection of furin cDNA. Furin cDNA-transfected MKN28 cells grew faster than did the mock controls. Moreover, furin mRNA expression in cultured gastric cancer cells was enhanced when PTHrP was added to the culture medium. These results suggest a link between PTHrP and furin in the regulation of gastric cancer cell growth. Furin might be involved not only in the production of the mature form of PTHrP, but also in promoting growth in gastric cancer cells. 相似文献

Serum transcobalamin II levels were measured in scrub typhus patients. Eighteen out of fifty-two patients admitted to Maharat Nakhon Ratchasima Hospital were diagnosed with scrub typhus infection. The serum unsaturated vitamin B12 binding protein (UBBC) and total vitamin B12 binding protein (TBBC) levels in these patients were significantly higher than in normal subjects (p < 0.001). The mean serum transcobalamin II level in the typhus patients was also significantly higher than in the normal subjects (p=0.004). There was a significant correlation between serum TCII levels and typhus IgM or IgG titers (p < 0.05), but not to total IgM levels. These findings indicate that patients with scrub typhus had stimulation of the recticuloendothelial system as a result of a considerable increase in transcobalamin II levels. 相似文献

The purpose of our study was to investigate the hematological status, vitamin B12 and folic acid absorption and intestinal pathology after Giardia lamblia infection in a rat model. Adult Wistar rats were assigned randomly to receive human giardia cysts orally in the amount of 5 x 10(5) or 1.0 x 10(6) cysts, or none in the controls. The results showed that all the rats injected with giardia cysts became infected. The cyst output in the infected rats varied considerably. In rats infected with 5.0 x 10(5) giardia cysts, the incubation period until cyst output was 10 days compared with 4 days in rats infected with the higher amount of 1.0 x 106 giardia cysts. The highest peaks for cysts output in these 2 groups were on days 4-33, which decreased gradually to days 40-58. The hematocrit and hemoglobin levels in the infected rats were statistically significantly lower than in the controls on days 16, 22, 33, and 37 post-infection (p < 0.05). A reverse relationship between giardia cyst output and hemoglobin concentration was found in the infected rats (p = 0.05). There were no significant differences in plasma vitamin B12 and folic acid levels between the infected rats and the control rats. No pathological changes were found in the small intestine of infected rats. These findings suggest that giardiasis did not affect the absorption of plasma vitamin B12 and folic acid but caused anemia in a rat model. 相似文献

The aims of this study were to investigate the prevalence and associated factors of female urinary incontinence in a Thai rural area and to investigate the impact of female urinary incontinence on quality of life. A population-based cross-sectional survey was performed from September 2003 to February 2004. A total of 1,126 women completed the questionnaires. The overall prevalence of urinary incontinence was 36.50%, i.e. stress urinary incontinence (33.60%), urge urinary incontinence (11.00%) and mixed urinary incontinence (8.07%). Urinary incontinence adversely affected quality of life; the mixed urinary incontinence group reported significantly greater impairment than the stress and urge urinary incontinence groups. Advancing age, labouring occupation, postmenopausal status, years since menopause, medical diseases, childbirth and vaginal delivery were associated with this problem. 相似文献

Effects of elephant garlic (Allium ampeloprasum) volatile oil (GVO) and trichothecene (T-2) toxin were studied in Swiss albino mice. The animals were 1) topically applied GVO, 2) topically applied T-2 toxin, 3) topically applied GVO followed by T-2 toxin (GVO/T-2), and 4) T-2 toxin application followed by GVO (T-2/GVO) on the right footpad. All animals were observed by Langerhans cell enumeration and pathological changes of the footpad on days 1, 3, 5 and 7. The number of Langerhans cells in the GVO treated group (1,097 +/- 33/mm2 to 1,624 +/- 19/mm2) was not significantly different when compared with the corresponding control left footpad (1,143 +/- 33/mm2 to 1,674 +/- 21/mm2). Langerhans cells density in T-2 toxin treated group (629 +/- 29/mm2to 1,090 +/- 31/mm2) was reduced by 20-35% of the opposite control footpad (962 +/- 40/mm2 to 1,392 +/- 29/mm2). Furthermore, GVO/T-2 and T-2/GVO treated mice showed a decrease in Langerhans cell number than a single T-2 toxin treated group. While Langerhans cells in T-2 toxin, GVO/T-2 and T-2/GVO groups revealed a smaller cell size with shortening dendritic processes when compare to the normal control group. Histopathological findings of the footpad skin in T-2 toxin treated group revealed epidermal desquamation and necrosis with edema and inflammatory cells infiltration. While GVO/T-2 and T-2/GVO showed a similar sequence but a lesser severe degree. These findings suggested that GVO both in pre- and posttreatment could protect T-2 toxin induced epidermal damage in a mouse footpad. 相似文献

AIM: To determine the effect of tetrahydrocurcumin (THC) on tumor angiogenesis compared with curcumin (CUR) by using both in vitro and in vivo models of human hepatocellular carcinoma cell line (HepG2). METHODS: The 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl-tetrazolium bromide (MTT) assay was used for testing the anti-proliferating activities of CUR and THC. In male BALB/c nude mice, 2 ×10^6 human HepG2 cells were inoculated onto a dorsal skin-fold chamber. One day after HepG2 inoculation, the experimental groups were fed oral daily with CUR or THC (300 mg/kg or 3000 mg/kg). On d 7, 14 and 21, the tumor microvasculature was observed using fluorescence videomicroscopy and capillary vascularity (CV) was measured. RESULTS: Pathological angiogenic features including microvascular dilatation, tortuosity, and hyper-permeability were observed. CUR and THC could attenuate these pathologic features. In HepG2-groups, the CV were significantly increased on d 7 (52.43%), 14 (69.17%), and 21 (74.08%), as compared to controls (33.04%,P 〈 0.001). Treatment with CUR and THC resulted in significant decrease in the CV (P 〈 0.005 and P 〈 0.001, respectively). In particular, the anti-angiogenic effects of CUR and THC were dose-dependent manner. However, the beneficial effect of THC treatment than CUR was observed, in particular, from the 21 d CV (44.96% and 52.86%, P 〈 0.05).CONCLUSION: THC expressed its anti-angiogenesis without any cytotoxic activities to HepG2 cells even at the highest doses. It is suggested that anti-angiogenic properties of CUR and THC represent a common potential mechanism for their anti-cancer actions. 相似文献
