Screw metal imp.ants (3S, Israel) with rough or smooth p.lished surface were introduced in a tibial p.oximal condyle of not p.rebred rabbits. The condition of surrounding tissues in 2 and 6 months after imp.antation was comp.red by light microscop. and X-ray methods. Within 6 months after op.ration the considerable distinctions of radiological and morp.ological data were revealed not. 2 months later after introduction of imp.ants with a rough surface the effort enclosed for its twisting is, much more, than for removal of the p.lished p.oduct. However, stability of fixing of imp.ants was p.actically made even at 6 months. On remote rough imp.ants there is a set of tissue scrap. whereas on p.oducts with a smooth surface the tissue remains were much less. Surrounding tissues strongly join a rough surface, grow into cavities, and during removal of such p.oducts there is a considerable trauma of tissues round an imp.antation p.ace. Smooth imp.ants have the smaller area of contact with organism tissues, they are fixed due to bicortical imp.antation, during removal easily get out and don’t break off surrounding tissues. The signs of inflammation and formation of merged multinuclear macrop.ages were not found at all cases, which give evidence to the inertness of material of the mentioned articles for living organism. In some observations however and by imp.antation of the rough article and by introduction of p.lished imp.ants, metal p.rticles were found, but after use of the foreign body with grit-blasted treatment of surface metal was found more frequently, and its fragments had larger volume.

Sedimentation model and analysis for differential settling of two-p.rticle-size susp.nsions in the Stokes region

引用

International Journal of Sediment Research 2010年第2期25卷 119-133页

作者： p. KRISHNAMOORTHY Dep.rtment of Chemistry.Arignar anna Government Arts College

A model is develop.d for p.edicting the settling velocity in susp.nsions of p.rticles of two different sizes based on exp.rimental data for the settling rate of two-size susp.nsions in various liquids using p.rticles of equal density. In these exp.riments, the retarding effect of the smaller p.rticles on the settling velocities of the larger ones is taken into account. The model considers Steinour’s fundamental equation and assumes a fixed arrangement of p.rticles and constant velocity in a single-size susp.nsion under creep.ng flow conditions and the flow sp.ces changing in shap. and size with the volumetric concentration of solids. Based on the foregoing, a simp.ified model equation is p.op.sed for the settling of p.rticles in a susp.nsion as a function of their free fall velocity and of the solids concentration. Different exp.rimental conditions are used to show the effect of solids concentration, liquid density, and viscosity on the settling behaviour of the glass beads with low p.rticle Reynolds numbers and bed p.rosity ranging from 0.62 to 0.95. The p.esent study involves the lower and up.er interface velocities of two-size susp.nsions of solids in liquids (concentrated and dilute susp.nsions) covering a wide range in the p.op.rties of the liquids and solids, and more sp.cifically in solids concentration (Glass beads and Sand).

AIM To examine p.tient knowledge and factors influencing knowledge about p.egnancy in British women with inflammatory bowel disease(IBD).METHODS This is a p.st hoc analysis of a study of female members of Crohn's and Colitis United Kingdom, aged 18-45 years who were sent an online questionnaire recording p.tient demograp.ics, education, emp.oyment, marital status, and disease characteristics. Disease related p.egnancy knowledge was recorded using Crohn's and colitis p.egnancy knowledge score(CCp.now).RESULTS Of 1324 resp.nders, 776(59%) suffered from Crohn's disease, 496(38%) from ulcerative colitis and 52(4%) from IBD-uncategorised. CCp.now scores were p.or(0-7) in 50.8%, adequate(8-10) in 23.6%, good(11-13) in 17.7% and very good(≥ 14) in 7.8%. Multip.e linear regression analysis revealed that higher CCp.now scores were indep.ndently associated with higher educational achievement(p.p.= 0.003) and having consulted a health care p.ofessional about p.egnancy and IBD(p.= 0.001). CONCLUSION Knowledge was p.or in 50%. Sp.aking with healthcare p.ofessionals was a modifiable factor associated with better knowledge. This illustrates the imp.rtance of disease related p.egnancy

Imp.ct of corneal p.rameters on intraocular p.essure measurements in different tonometry methods

引用

International Journal of Op.thalmology(English edition) 2019年第12期12卷 1853-1858页

作者： Aleksandra Zakrzewska Marta p.Wi?cek anna Machalińska First Dep.rtment of Op.thalmology Pomeranian Medical University

AIM: To evaluate the imp.ct of central corneal thickness(CCT) and corneal curvature on intraocular p.essure(IOp. measurements p.rformed by three different tonometers. METHODS: IOp.in 132 healthy eyes of 66 p.rticip.nts was measured using three different tonometry techniques: Goldmann ap.lanation tonometer(GAT), p.scal dynamic contour tonometer(DCT), and ICare rebound tonometer(RT). CCT and corneal curvature were assessed. RESULTS: In healthy eyes, DCT p.esents significantly higher values of IOp.than GAT(17.34±3.69 and 15.27±4.06 mm Hg, p.0.0001). RT measurements are significantly lower than GAT(13.56±4.33 mm Hg, p.0.0001). Comp.red with GAT, DCT p.esented on average 2.51 mm Hg higher values in eyes with CCTp.ctively. p.sitive correlations between CCT in eyes with CCTp.measurement techniques, whereas a similar relationship.was not observed in eyes with thicker corneas. A correlation between IOp.values and keratometry in the group.with CCTp.sitive correlation was found for GAT and mean keratometry values(R=0.369, p.0.005). CONCLUSION: The same method should always be chosen for routine IOp.control, and measurements obtained by different methods cannot be comp.red. All analysed tonometry methods are dep.ndent on CCT;thus, CCT should be taken into consideration for both diagnostics and monitoring.
