瘰疬性苔藓:39例患者的前瞻性研究

世界核心医学期刊文摘（皮肤病学分册） 2005年第9期1卷 51-52页

作者： s.n.al A. Bhattacharya s.n. B-16 F-1 Dilshad Garden Delhi 110095 India Dr.

Background:Lichen scrofulosorum is considered a rare form of cutaneous tuberculosis. Current information is based on case reports and case series with a small number of patients. Methods:Thirty-nine patients with Lichen scrofulosorum were followed during the period January 1996 to December 2002. Clinical details(age,sex,durationofdisease,associatedtubercularlesions, extent and distribution of skin lesions), laboratory parameters (hemoglobin, total leucocytic counts, erythrocyte sedimentation rate, Mantoux test, pres.n.e of BCG scar), and response to antitubercular treatment were recorded and analyzed. Results:7.6%patients of all (511) patients with cutaneous tuberculosis had Ls. 22 (56.4%) were males and 32 (84%) were below 15 years of age. Twenty-eight (72%) had an associated focus of tuberculosis elsewhere in the body; 13 (33%) had tubercular lymphadenopathy, while 11 (28%), three (8%) and six (15%)had pulmonary tuberculosis, intracranial tuberculosis and other forms of cutaneous tuberculosis, respectively. six (15%) had tubercular focus at multiple sites. Eleven (28%) had no other identifiable focus of tuberculosis. Twenty-eight (72%) had evidence of receiving BCG vaccination. Trunk was the commonest (100%) affected *** two groups with and without associated tubercular focus were not different with respect to age, sex, duration of disease, hemoglobin, total leukocyte count, erythrocyte sedimentation rate, Mantoux test positivity, and pres.n.e of BCG scar. Mycobacteria tuberculosis could not be detected either on acid fast bacilli (AFB) staining or on culture from biopsies of Ls lesions. All patients (including those without evidence of tubercular focus) responded to antitubercular treatment, signifying an underlying occult tubercular focus as etiology. Conclusions:Lichen scrofulosorum is an uncommon but not rare cutaneous manifestation of tuberculosis. A high index of suspicion and awareness is required for diagnosis. systemic tuberculosis is often associate

Journal of Materials science & Technology 2011年第7期27卷 601-606页

作者： s.n. Hosseini T. Mousavi F. Karimzadeh M.H. Enayati Department of Materials Engineering Nanotechnology and Advanced Materials Institute Isfahan University of Technology84156-83111 Iran

The nanostructured CoAl intermetallic compound was produced by mechanical alloying （MA） of the Co50Al50 elemental powder mixture in a planetary high energy ball mill. The ordered B2-CoAl structure with the grain size of about 6 nm was formed via a gradual reaction after 10 h of MA. A thermodynamic analysis of the process was also done. The results showed that the intermetallic compound of CoAl had the minimum Gibbs free energy compared to solid solution and amorphous states indicating the initial MA product was the most stable phase in the Co-Al system which was changed to a partially disordered structure with a steady long-range order of 0.82 at further milling. This amount of disordering caused the enthalpy of final product to show an increase of about 5.1 kJ·mol-1. Calculation of enthalpy related to the triple defect formation revealed that the enthalpy required for Al anti-sites formation was about 3 times greater than that for Co anti-sites formation.
