m.ngifera indica L. is a species of m.ngo in the Anacardiaceae fam.ly. It is found in the wild in tropical regions and cultivated varieties have been introduced to other warm.regions of the world. This present study aim.d to investigate the in vitro antim.crobial activities of m.thanol and ethanol extracts of m.ngo seed against 25 representatives gram.positive, gram.negative, acid fast bacteria and fungi. m.ngo fruit seed were extracted by Soxhlet using m.thanol and ethanol as solvents. The extracts were tested against the m.croorganism. using disc diffusion m.thod at different concentrations: 5 m./m., 3.75 m./m., 3.125 m./m., 2.5 m./m., 1.875 m./m. and 1.25 m./m.). In vitro antibacterial activities of m.thanol and ethanol extracts of m.ngo bulb showed inhibitions to tested organism. with variable inhibition zones. Except one organism.(Rhodococcus equi), no resistance am.ng the tested strains was shown. The m.an zone of inhibition produced ranged between 5 m.and18 m.with18 m./m.cobacterium.sm.gm.tis showed the highest zone of inhibition. In m.st test strains com.arable zones of inhibitions were noted for both m.thanol and ethanol extract. Candida albicans and Aspergilllus niger were both inhibited by the extracts. The m.thanol and ethanol extracts of m.ngo seed showed good inhibitory effects against alm.st all tested strains. The inhibition zones produced by m.ngo extract were less than those produced by standard positive control drug. This could be due to low diffusion rate of m.ngo extract in agarose m.dium. a thing needed to be further investigated. The products are potential new antim.crobial therapy in the ethnopharm.cology dom.in.

Potential energy curves for the lowest electronic states of LaB and LaB- have been calculated by ab initio *** diffusion m.nte Carlo m.thod has been em.loyed in com.ination with three different trial functions. Spectroscopic constants have also been num.rically derived for the neutral m.lecule and com.ared with the only available theoretical work;^（[19]） however, predictions are provided for the corresponding constants for the anionic species which have not been reported yet. Our calculations suggest the high spin quintet state of LaB as the ground state with the triplet state higher in energy irrespective of the type of the functional used. This suggestion is in good accordance with the previous theoretical results calculated at B3LYP/LANL2DZ level of theory, whereas it contradicts with the prediction based upon B3LYP/SDD calculations in the sam. study. m.reover, variations of the perm.nent dipole m.m.nts as a function of the internuclear separations for the two electronic states of the neutral m.lecule have been studied and analyzed.

AIm.To define the financial and m.nagem.nt conditions required to introduce a fem.osecond laser system.for cataract surgery in a clinic using a fuzzy logic ***：In the sim.lation perform.d in the current study,the costs associated to the acquisition and use of a com.ercially available fem.osecond laser platform.for cataract surgery（VICTUS,TECHNOLAS Perfect Vision Gm.H,Bausch ＆ Lom.,m.nich,Germ.ny） during a period of 5y were considered.A sensitivity analysis was perform.d considering such costs and the countable am.rtization of the system.during this 5y ***,a fuzzy logic analysis was used to obtain an estim.tion of the m.ney incom. associated to each fem.osecond laser-assisted cataract surgery（G）. RESULTS：According to the sensitivity analysis,the fem.osecond laser system.under evaluation can be profitable if 1400 cataract surgeries are perform.d per year and if each surgery can be invoiced m.re than $*** contrast,the fuzzy logic analysis confirm.d that the patient had to pay m.re per surgery,between $661.8 and $667.4 per surgery,without considering the cost of the intraocular lens（IOL）.CONCLUSION：A profitability of fem.osecond laser system. for cataract surgery can be obtained after a detailed financial analysis,especially in those centers with large volum.s of *** cost of the surgery for patients should be adapted to the real flow of patients with the ability of paying a reasonable range of cost.
