The effects of carbamazepine (CBZ) and sodium valproate (SV) monotherapy on visual evoked potentials (VEP) were studied in 18 epileptic children receiving CBZ and nine epileptic children receiving SV. Pattern reversal VEP were determined before the administration of antiepileptic drugs (AED) and 1 year later during which time the patients had received AED. The VEP amplitude showed no consistent changes after 1 year of CBZ and SV therapy, but VEP P-100 latencies were significantly prolonged after 1 year of CBZ therapy. We conclude that CBZ causes a slowing down of central impulse conduction and that VEP is useful to evaluate the effects of AED within the central nervous system. 相似文献

目的观察PDGFB链基因的TFO和VEGF的反义寡核苷酸AON对荷瘤大鼠脑胶质瘤增殖和细胞凋亡的影响。方法所有大鼠均在立体定向导引下行右尾状核区微量灌注20μL生理盐水中含1×106C6胶质瘤细胞。在细胞接种后第8天,实验Ⅰ组原位注射含TFO1·0mg的20μL生理盐水,实验Ⅱ和Ⅲ组则分别原位注射含TFO1·0mg AON0·125mg和TFO1·0mg AON0·250mg的20μL生理盐水。以后每隔72h原位注射相同剂量的药物,共注射3次。对照组仅在相同时间原位注射20μL生理盐水。实验3周时处死所有的大鼠,观察肿瘤的生长情况,流式细胞仪观察PDGFB链基因(PDGF-B)、VEGF、PCNA及细胞凋亡的变化。结果实验Ⅰ组的成瘤抑制率为53·1%,实验Ⅱ组为81·4%,实验Ⅲ组为93·1%,三组肿瘤体积比较差异有统计学意义,P<0·01。TFO对胶质瘤细胞PDGF-B、VEGF和PCNA表达有明显的抑制作用;TFO能使胶质瘤细胞凋亡增加。联合应用TFO和AON能更好地抑制PDGF-B、VEGF和PC-NA的表达,使胶质瘤细胞增殖能力进一步降低,细胞凋亡进一步增加。结论联合应用TFO和AON能更有效地抑制肿瘤生长和细胞增殖,促进胶质瘤细胞凋亡。 相似文献

Tamoxifen and its analogues 4-hydroxytamoxifen, toremifene, 4-
hydroxytoremifene, clomifene and droloxifene were tested for clastogenic
effects in a human lymphoblastoid cell line (MCL-5) expressing elevated
native CYP1A1 and containing transfected CYP1A2, CYP2A6, CYP2E1 and CYP3A4
and epoxide hydrolase and in a cell line containing only the viral vector
(Ho1). MCL-5 or Ho1 cells were incubated with 4-hydroxytamoxifen,
4-hydroxytoremifene, clomifene or droloxifene and the incidence of
micronuclei estimated. With MCL-5 cells there was an increase in
micronuclei with 4-hydroxytamoxifen, 4- hydroxytoremifene and clomifene but
not with droloxifene. With Ho1 cells only 4-hydroxytamoxifen and
4-hydroxytoremifene caused an increase in micronuclei. MCL-5 cells were
incubated with tamoxifen, 4- hydroxytamoxifen, toremifene, droloxifene,
clomifene or diethylstilbestrol (0.25-10 microg/ml) for 48 h and subjected
to 3 h treatment with vinblastine (0.25 microg/ml) to arrest cells in
metaphase. The incidence of cells with chromosomal numerical aberrations
(aneuploidy) was increased in cells treated with tamoxifen,
4-hydroxytamoxifen, toremifene, clomifene and diethylstilbestrol but not
droloxifene. The frequency of cells with structural abnormalities
(excluding gaps) was increased in cells treated with tamoxifen and
toremifene but not 4-hydroxytamoxifen, clomifene, droloxifene or
diethylstilbestrol. The clastogenic activities of tamoxifen (35 mg/kg),
toremifene (36.3 mg/kg), droloxifene (35.2 mg/kg) and diethylstilbestrol
(25 mg/kg) were compared in groups of four female Wistar rats. Each
chemical was dissolved in glycerol formal, administered as a single dose by
gavage and hepatocytes isolated by collagenase perfusion 24 h later. The
cells were cultured in the presence of epidermal growth factor (40 ng/ml)
for 48 h, colchicine (10 microg/ml) being added for the final 3 h of
incubation. At least 100 chromosomal spreads were examined from each animal
for the presence of numerical and structural abnormalities. The incidences
of aneuploidy following treatment were: tamoxifen 81%, toremifene 46%,
droloxifene 9.6%, diethylstilbestrol 45.7%, vehicle control 5.3%. The
incidences of chromosomal structural abnormalities excluding gaps were:
tamoxifen 4.3%, toremifene 0.8%, droloxifene 0.5%, diethylstilbestrol 0.8%,
control 0.5%. The incidence of chromosomal structural aberrations excluding
gaps in the treated animals was not statistically significantly different
from controls except in the tamoxifen-treated group. Tamoxifen (35 mg/kg
per os) and toremifene (36.3 mg/kg per os) were dosed to rats for 4 weeks
and chromosomal spreads made from hepatocytes. The incidences of aneuploidy
were: tamoxifen 94%, toremifene 57%, control 6.5%. The incidences of
chromosomal aberrations excluding gaps were: tamoxifen 12%, toremifene 1%,
control 0.5%. The incidence of tamoxifen-induced chromosomal structural
abnormalities was significantly elevated compared with control levels. The
results demonstrate that tamoxifen and toremifene are the only two drugs
tested in the study that cause chromosomal structural and numerical
aberrations in vitro and tamoxifen is the only drug that induces both these
effects in rat liver cells stimulated to divide in culture following oral
dosing. Since chromosomal mutations require cell division for their
manifestation and tamoxifen is the only compound of those tested that
causes hyperplasia in the rat liver, chromosomal aberrations and aneuploidy
in the rat liver would only be expected to occur following treatment with
tamoxifen alone, although aneuploidy could be induced by toremifene in
conjunction with a promoter such as phenobarbitone.

In a pilot study six patients with active ulcerative colitis and six healthy controls were given fish oil (MaxEPA) containing 3-4 g of eicosapentaenoic acid daily for a period of 12 weeks. There was a significant improvement in the patients' symptoms and histological appearance of the rectal mucosa by the end of the treatment period. There was significant fall in neutrophil chemiluminescence during treatment in patients, whereas no change was observed in the control group. Neutrophil leukotriene B4 levels fell significantly during treatment. Serum from patients receiving fish oil was significantly less chemotactic for neutrophils compared with control serum. Eicosapentaenoic acid inhibited neutrophil chemotaxis and chemiluminescence in vitro. The omega-3 fatty acids, which occur naturally in fish oils, may exert a beneficial effect by decreasing the production of inflammatory mediators. 相似文献

GRINES M.D. ON BEHALF OF THE PRIMARY ANGIOPLASTY IN MYOCARDIAL INFARCTION INVESTIGATORS 《Journal of interventional cardiology》1999,12(2):101-108
To study the additive benefits of routine stent implantation in patients undergoing primary percutaneous transluminal coronary angioplasty (PTCA) at experienced centers, we compared the outcomes of the 982 patients undergoing PTCA for acute myocardial infarction (AMI) in the Primary Angioplasty in Myocardial Infarction-2 (PAMI-2) trial (only 1% of whom were stented) to the 312 patients in the PAMI Stent Pilot Trial (236 [76%] of whom were stented). The inclusion and exclusion criteria, PTCA methodology, and definitions used were prespecified to be identical between the two trials. Compared to the primary PTCA approach in PAMI-2, the strategy of stenting all eligible lesions in the PAMI Stent Pilot Trial was associated with reduced rates of in-hospital death (0.6% vs 2.7%, P = 0.03), reinfarction (1.3% vs 4.6%, P = 0.008), recurrent ischemia (3.5% vs 11.6%, P < 0.0001), target vessel revascularization (7.3% vs 11.4%, P = 0.04), and a shorter hospital stay (6.4 ± 4.4 vs 7.1 ± 6.2 days, P = 0.01). By multiple logistic regression analysis in 1,294 patients, stent implantation versus PTCA only was the strongest predictor of freedom from the composite in-hospital end point of death, reinfarction, or target vessel revascularization (TVR) (8.3% vs 15.0%, multivariate odds ratio = 0.4, P < 0.0001). These data strongly suggest that despite the excellent results achieved when primary PTCA is performed by experienced operators, the short-term outcomes of mechanical reperfusion can be further improved by a primary stent strategy. 相似文献
