The efficacy of coconut tree sawdust (CTS), eggshell (ES) and sugarcane bagasse (SB) as alternative low-cost biosorbents for the removal of Cu(II), Pb(II) and Zn(II) ions from aqueous solutions was investigated. Batch adsorption studies were carried out to evaluate the effects of solution pH and initial metal concentration on adsorption capacity. The optimum biosorption condition was found at pH 6.0, 0.1 g biomass dosage and at 90 min equilibrium time. The adsorption data were fitted to the Freundlich and Langmuir isotherm models. The adsorption capacity and affinity of CTS, ES and SB were evaluated. The Freundlich constant (n) and separation factor (RL) values suggest that the metal ions were favourably adsorbed onto biosorbents. The maximum adsorption capacities (Q) estimated from the Langmuir isotherm model for Cu(II), Pb(II) and Zn(II) were 3.89, 25.00 and 23.81 mg/g for CTS, 34.48, 90.90 and 35.71 mg/g for ES, and 3.65, 21.28 and 40.00 mg/g for SB, respectively. The characterisation studies were performed using Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectrometer (EDX) and Fourier Transform Infrared Spectrometer (FTIR). Interaction with metal ions led to the formation of discrete aggregates on the biosorbents surface. The metal ions bound to the active sites of the biosorbents through either electrostatic attraction or complexation mechanism.

在新南威尔士东北部托林顿地区的花岗岩和森林覆盖地带进行了简要的试验,研究评价铀的水系地球化学取样的效果。在水系沉积物以及流经含微量铀的钨矿点的水中,均有铀量异常。诸如自然汇水区和水系沉积物中的有机物含量等相互联系的一些因素影响铀的分布,而水系沉积物中有机物含量对铀量的影响最为明显。沉积物中有机物含量的变化与河道中植物有机碎片和木炭的聚集有关,这是由于为稀疏森林所覆盖的地表受层状冲刷作用所致,特别是在地势高的汇水区内。有机物从季节性流动的河水中吸附铀,在这种环境下,当设计和解释测量结果时,必须仔细考虑水系沉积物中铀含量的季节性变化。

Neural cell adhesion molecule-180 expression as a prognostic criterion in colorectal carcinoma:Feasible or not?

AIM： To evaluate the frequency of neural cell adhesion molecule （NCAM）-180 expression in fresh tumor tissue samples and to discuss the prognostic value of NCAM-180 in routine clinical practice.METHODS： Twenty-six patients （16 men, 10 women） with colorectal cancer were included in the study. Fresh tumor tissue samples and macroscopically healthy proximal margins of each specimen were subjected to flow-cytometric analysis for NCAM-180 expression.RESULTS： Flow-cytometric analysis determined NCAM-180 expression in whole tissue samples of macroscopically healthy colorectal tissues. However, NCAM-180 expression was positive in only one case （3.84%） with well-differentiated Stage Ⅱ disease who experienced no active disease at 30 months follow-up. CONCLUSION： As a consequence of the limited number of cases in our series, it might not be possible to make a generalisation, nevertheless the routine use of NCAM-180 expression as a prognostic marker for colorectal carcinoma seems to be unfeasible and not cost-effective in clinical practice due to its very low incidence.

AIM： TO investigate the effect of exogenous erythro- poietin （EPO） administration on acute lung injury （ALI） in an experimental model of sodium taurodeoxycholate- induced acute necrotizing pancreatitis （ANP）. METHODS： Forty-seven male Wistar albino rats were randomly divided into 7 groups： sham group （n = 5）, 3 ANP groups （n = 7 each） and 3 EPO groups （n = 7 each）. ANP was induced by retrograde infusion of 5% sodium taurodeoxycholate into the common bile duct. Rats in EPO groups received 1000 U/kg intramuscular EPO immediately after induction of ANP. Rats in ANP groups were given 1 mL normal saline instead. All animals were sacrificed at postoperative 24 h, 48 h and 72 h. Serum arnilase, IL-2, IL-6 and lung tissue malondialdehyde （MDA） were measured. Pleural effusion volume and lung/body weight （LW/BW） ratios were calculated. Tissue levels of TNF-a, IL-2 and IL-6 were screened immunohistochemically. Additionally, ox-LDL accumulation was assessed with immune-fluorescent staining. Histopathological alterations in the lungs were also ***： The mean pleural effusion volume, calculated LW/BW ratio, serum IL-6 and lung tissue MDA levels were significantly lower in EPO groups than in ANP groups. No statistically significant difference was observed in either serum or tissue values of IL-2 among the groups. The level of tumor necrosis factor-（~ （TNF-（~） and IL-6 and accumulation of ox-LDL were evident in the lung tissues of ANP groups when compared to EPO groups, particularly at 72 h. Histopathological evaluation confirmed the improvement in lung injury parameters a^er exogenous EPO administration, particularly at 48 h and 72 h. CONCLUSION： EPO administration leads to a significant decrease in ALI parameters by inhibiting polymorphonuclear leukocyte （PMNL） accumulation, decreasing the levels of proinflammatory cytokines in circulation, preserving microvascular endothelial cell integrity and reducing oxidative stress-associated lipid peroxidation and therefore, can

目的:报告免疫力正常少年的隐球菌脑膜炎1例,早期表现为复视和双眼视力低下。方法:病例报告。结果:男,17岁,两眼视物模糊并复视3wk,伴随严重的搏动性头痛、恶心、呕吐及低热。经体格检查无发热及假性脑膜炎迹象。双眼视力为6/15并视野缩窄。双眼前段正常。眼外肌运动表明双侧第六神经麻痹。眼底检查显示双侧视盘充血和轻度隆起。CT扫描大脑正常,无颅内肿块或脑室异常。腰椎穿刺发现高开放压>300mmH2O。脑脊液显微镜下及培养均存在新型隐球菌。本例由神经医疗组联合处理。患者开始静脉注射两性霉素B和氟康唑,神经症状1wk后恢复,双眼视力提高到6/6,同时周边视野恢复。随着第六神经麻痹的康复双眼复视得到好转。结论:本例强调了隐球菌脑膜炎进展缓慢的性质。即使免疫功能正常,也不会存在明显的假性脑膜炎特征,复视可能是脑膜炎患者的早期表现之一。
