DMEM培养基体外培养阴道毛滴虫效果的实验观察

目的研究阴道毛滴虫在不同浓度胎牛血清DMEM培养基中的生长效果,比较阴道毛滴虫在DMEM培养基与15%肝浸汤培养基中的生长情况。方法调节DMEM培养基中胎牛血清终浓度分别为10%、20%、50%,接种密度为15×104/ml的阴道毛滴虫,置37℃恒温箱培养,每24小时取样一次,光镜观察虫体形态,利用血球计数板计数阴道毛滴虫增殖密度并计算增殖倍数。接种密度为1. 8×104/ml的阴道毛滴虫分别至DMEM、15%肝浸汤培养基中,比较阴道毛滴虫生长时间、增殖倍数及形态。结果接种密度为15×104/ml的阴道毛滴虫在终浓度为10%、20%、50%胎牛血清的DMEM培养基内分别培养48 h、24 h、72 h达增殖高峰。接种密度为1. 8×104/ml的阴道毛滴虫在DMEM培养基中120 h增殖倍数达高峰,为32. 63倍,虫体形态大而圆;在15%肝浸汤培养基中96 h增殖倍数达高峰,为59. 40倍,虫体形态多呈梨形;虫体在DMEM培养、肝浸汤培养基中生存时间最长分别为14 d、5 d。结论阴道毛滴虫在DMEM培养基中增殖率低于在肝浸汤培养基中,但虫体在DMEM培养基中存活时间更长,其形态大而圆,因此DMEM培养基适合阴道毛滴虫的体外生长,保种,染色,及形态观察。     

阴道毛滴虫标本传统染色方法的改良

阴道毛滴虫染色方法的改进报道甚少。由于其鞭毛着色难以获得理想的效果，因此染色方法的改良仍是制作实验教学标本中值得探讨的问题。我室于1998年底在制作教学标本过程中采用传统吉氏、瑞氏混合液配制各种不同比例的混合染液对经培养后的阴道毛滴虫标本涂片染色，摸索出一种合适的比例浓度，改进了阴道毛滴虫着色效果。

介绍一种新的阴道毛滴虫染色涂片标本制作方法

滴虫性阴道炎是临床上常见的一种妇科疾病 ,在教学中 ,以往常用的阴道毛滴虫标本的制作方法有直接涂片法和培养法。直接涂片法虽然虫体和鞭毛的染色较好 ,但往往因阴道分泌物及脱落细胞等杂质较多而影响到标本的质量 ;培养法因转种时间不恰当及转种时易造成污染而直接影响到阴道毛滴虫的染色效果。本方法采用人工消化法取得了较好的效果。1　制作方法1 1　消化液的配制　胰蛋白酶 30ｍｇ ,溶于 10 0ｍｌ生理盐水中 ,混匀。1 2　涂片的方法　将在患者处取得的阴道毛滴虫标本 ,加入 3ｍｌ生理盐水于离心管中混匀。 10 0 0转 /分离心 15分钟 ,…     

乳酸杆菌产生的微环境对阴道毛滴虫的影响及阴道毛滴虫小鼠模型的建立

目的研究乳酸杆菌产生的微环境对阴道毛滴虫的影响并建立实验性阴道毛滴虫动物模型。方法在阴道毛滴虫生长高峰期加入乳酸,观察阴道毛滴虫在不同乳酸浓度(0.5%、1%、2%)的肝浸汤中的死亡情况,全部死亡后做72h滴虫复苏实验,获取酸度与滴虫间的关系;根据上一步乳酸实验得到的数据,于滴虫生长高峰期分别加入3.0×108/ml的乳酸杆菌0.25ml,0.5ml,1.0ml,2.5ml,观察不同乳酸杆菌浓度的培养基中滴虫死亡情况;将阴道毛滴虫接种于小鼠腹腔,观察小鼠形态如毛发、体形、精神状态变化,以及腹腔脏器病理改变。结果0.5%、1%、2%乳酸浓度下阴道毛滴虫经2h全部死亡,但0.5%浓度组的滴虫复苏成功;乳酸杆菌浓度为0.5×108/ml时比其他浓度组中滴虫的死亡率明显要高;感染阴道毛滴虫的小鼠出现一系列病态症状,并有一系列病理改变。结论1%、2%的乳酸浓度对阴道毛滴虫有杀灭作用,但乳酸浓度为0.5%时对滴虫仅有抑制作用;0.5×108/ml的乳酸杆菌对阴道毛滴虫生长的抑制作用最强。阴道毛滴虫具有较强的致病力,采用腹腔接种可建立可靠的动物模型。

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.     

Research of combined liver-kidney transplantation model in rats

Objective： To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods： SD rats served as both donors and recipients. 4℃ sodium lactate Ringer＇s was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava （IVC） inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results： Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion： This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.

BLOOD PRESSURE CHANGE WITH AGE IN SALT-SENSITIVE TEENAGERS

Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P＜ 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P＜ 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.     

Development on Adjustable Calibration Marker for Shock Wave Focus

Shock wave lithotripsy （SWL） is a treatment of choice for upper urinary stones. However, this procedure is inappropriate for obese patients because the focus is often unable to reach the target owing to the limited focal distance in shock wave source. Although treating such patients in a blast path may increase the application length of shock wave source, it＇s difficult to find this path on the lithotripter monitor. For this reason, we invented an adjustable calibration marker in order to set an effective focus in the shock wave hath.     

Study on the TCM Pathogenesis of Angiopathic Complications of Type II Diabetes

Excess production of reactive oxygen species(ROS)of mitochondrion mediated by hyperglycemia is the common pathogenesis of angiopathic complications of diabetes.TCM holds that the damp from the dysfunction of spleen.kidney and liver is the causative factor of complications of diabetes.This is similar to the mechanism of Ros resulting in angiopathic complications of diabetes.When the angiopathic complications of type II diabetes mellitus(T2DM)are difierentiated as caused by turbid damp in TCM can be explained as ROS.Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis,the treating principle should be dissolving the damp to remove the obstruction.     

Leptin, Ghrelin and TNF-α before and after Hypo-caloric Traditional Chinese Diet and Auricular Acupuncture

INTRODUCTION Obesity is a complex emergent problem, which can be possibly solved not only by the diet but also by the life style and promotion of a constant physical exercise. 1, 2 No doubt careful attentions must be given to the nutritional condition of obese people, the dietary habits, the somatic build (i.e. distribution of fat mass) and the organic functions linked to formation of the fat mass. All the parameters should be constantly monitored before, during and after a diet treatment. 3, 4, 5
