Objective To determine the changes in brain dopamine transporter and serotonin transporter in mice receiving propofol anesthesia, 125I-?-CIT binding was studied.Methods Twenty-seven Kunming mice ,weighing 18-22g ,were randomly assigned to receive either intraperitoneal propofol 100 mg/kg (n=9) or 200 mg/kg(n=9) or 10% intralipid (used as control,n=9) in equal liquid volume respectively. 10 min after intraperitoneal administration, 0.1ml 2?Ci 125I-?-CIT was given intravenously via the tail vein. Two hours later animals were decapitated. Brains were rapidly removed and dissected on ice and cerebellum, hypothalamus, striatum and cerebral cortex were separated. Brain tissues were weighed and the radioactivity of 125I-?-CIT in different brain regions was measured.Results 125I-?-CIT binding to dopamine transporter or serotonin transporter decreased significantly in propofol groups as compared with that in control group. The decrease in binding was greater in 200 mg/kg propofol group (P

Objective To investigate the effects of propofol on learning and amnesia in the old miceMethods The normal Kunming mice were trained in a one-trial, step-through, light-dark passive avoidance paradigm Propofol (50 or 100 mg/kg) was administered intraperitoneally 15 min before training ,and propofol (100 or 200 mg/kg) separately 30 min and 6 h in the immediate post-training period The latency of escaping into a darkened chamber and the wrong number of entering darkened chamber were recorded Animals were tested for recall at 24th h post-training time The activity of acetyltransferase was determined with radiommunoassay in the brain 3h after administrationResults All control animals were liable to learn the task as judged by their increased latencies to enter the darkened chamber at 24th h post-training time After administration with propofol 50 mg/kg or 100 mg/kg, the latencies were reduced (246 and 208,repectively), compared with control (P

Objective To determine if propofol can affect uptake of dopamine ( DA) by dopamine transporter (DAT) . Methods Chinese hamster ovary (CHO) cells in which DAT was highly expressed were incubated with H-dopamine in the presence or absence of propofol. Uptake of H-DA was measured. The kinetic parameters Vmax and Km were calculated. Results Propofol significantly inhibited uptake of DA by DAT in CHO cells as compared with the control ( P

Objective To evaluate the genotoxicity of europium nitrate to the Vicia faba L root-tip cells. Methods The primary roots of Vicia faba L were cultured for 6 hours in the solution of Eu series(64,32,16,8,4,2,1 ?g/ml) at 25℃.And then the roots were repair-cultured in double distilled water for 24 h. The root tips of Vicia faba L were dissected and fixed,stained and the micronucleus rate,mitotic index and the rate of chromosomal aberrations were determined. Results From 1 ?g/ml to 32 ?g/ml,the rate of micronucleus increased with the increasing of the europium nitrate dosage(D),presented a dosage-effect relationship(r=0.949). From 2 ?g/ml to 64 ?g/ml,mitotic index decreased with the increasing of the europium nitrate dosage,presented a dosage-effect relationship(r=-0.852). From 1 ?g/ml to 64 ?g/ml,chromosome fragments(CF) and frequency of chromosomal aberrations(FCA) increased with the increasing of the europium nitrate dosage with a dosage-effect relationship significantly(rD-CF=0.915,rD-FCA=0.872). Conclusion Europium nitrate has the certain genetic toxicity to the Vicia faba L root-tip cells. The chromosome fragments may be one of the reasons to produce micronucleus.

Objective To compare the therapeutic effect of auricular acupuncture with that of hormone substitution on perimenopause syndrome patients to study the mechanism of auricular therapy.Methods Totally 68 female cases were randomized into the auricular acupuncture group and hormone group,34 cases in each.The auricular acupuncture group was given electro-acupuncture on Neifenmi(CD18),Ovarium,and Uterus;and the hormone group was given Tibolone.Before and after treatment,record Kupperman score and determine serum estradiol(E2),follicle-stimulating hormone(FSH)and luteotropic hormone(LH)respectively.Results After treatment,the Kupperman scores of both groups were decreased,the level of E2 increased obviously,FSH and LH decreased,the difference was significant(P0.05).Conclusion The auricular therapy can effectively relieve the perimenopause syndrome and improve the reproductive endocrine function of perimenopause females.

Objective To evaluate the surgical effect for congenital nystagmus (CN) with an abnormal head position in all three axes of a predominant head turn. Design Retrospective case series. Participants 11 patients with horizontal nystagmus and abnormal head position treated in Xingtai Eye Hospital during 2003-2008. All had an abnormal head position in all three axes with a predomi-nant head turn. Methods Recession of the yoke muscles responsible for the slow phase of nystagmus (one medial rectus of 6mm, and one lateral rectus 8 mm), and simultaneously resection of the yoke muscles responsible for the fast phase of nystagmus (the other lateral rectus 9 mm, and medial rectus 7 mm) were performed. The follow-up was from 6 to 20 months. Main Outcome Measures The visual acuity of both eyes in primary position, the degree of head turn, chin elevation or depression, head tilt. Results At the last follow-up, the all 11 patients undergoing the operation for CN gained two or more lines of Snellen acuity with both eyes in primary position for be-ing corrected best. The postoperative mixed head position of 9 cases got disappear or ≤ 10°. Of 1 case developed overcorrection of the head turn. 1 case has the head turn of ≤15°, and 1 case remained the head turn of 25°. Conclusion Recessions and resections of the horizontal yoke rectus muscles in nystagmus with blockage position, when the head turn predominates over the vertical and torsional components, are effective in diminishing the abnormal head position on all three axes, and improve the visual acuity with both eyes in primary position.

OBJECTIVE:To investigate the clinical efficacy of levodopa combined with comprehensive therapy for ametropic amblyopia children and teenagers and its effeets on pattern visual evoked potential(P-VEP)and visual function. METHODS:70 pa-tients(80 eyes)with ametropic amblyopia were randomly divided into observation group(35 cases,40 eyes)and control group(35 cases,38 eyes). Control group received comprehensive therapy as wearing correctional glasses,occlusion therapy and visual stimu-lation training;observation group additionally received levodopa 0.125(d1-3)-0.25 g/time,bid,on the basis of control group for 6 months. Therapeutic efficacy,P-VEP,Visual sensitivity and visual function were compared between two groups,and the occur-rence of ADR was recorded. RESULTS:The effective rate of observation group(92.50%)was significantly higher than that of con-trol group(76.32%),with statistical significance(P<0.05);the wave amplitude of P-VEP P100 in observation group were signifi-cantly greater than in control group,and the incubation period was significantly shorter than control group,with statistical signifi-cance(P<0.05);visual acuity under different spatial frequency contrast were significantly higher than control group,and correc-tion convergence range and correction separation range of observation group were significantly greater than those of control group, while corrected near stereo vision was significantly less than control group,with statistical significance (P<0.05). There was no statistical significance in ADR incidence between 2 groups (P>0.05). CONCLUSIONS:Levodopa combined with comprehensive therapy can improve the function of visual central neurons,and improve visual acuity and binocular stereo vision functions so as to improve therapy efficacy.

Objective To prepare the solid dispersion of ginsenoside Rg3 with different carriers and measure their solubility and dissolution characterisitics. Methods The solid dispersion of ginsenoside Rg3 was prepared by the melted and dissolved methods with Poloxamer 188(F68), PVP k29/32, and PEG 6000 as carriers, respectively. The equilibrium solubility and dissolution characteristics of the solid dispersion in vitro were measured by HPLC. The existing state of ginsenoside Rg3 in the solid dispersion was identified by the differential scanning calorimetery. Results The ginsenoside Rg3 was completely dispersed in carrier and formed a mixture with carriers. The solubility and dissolution rates of all solid dispersion were increased obviously. Conclusion The solid dispersion of ginsenoside Rg3 with Poloxamer 188 as carriers is better on improving dissolution and solubility than those with PVP and PEG 6000 as carriers.
