A novel, sim.le approach.to th. synth.sis of m.crocyclic Sch.ff base ligand resulted from.th. condensation of bisaldeh.de and eth.lenediam.ne was prepared (7, 8, 15, 16, 17, 18-h.xah.drodibenzo (a, g) (14) annulene) (L) and its com.lexes were synth.sized and ch.racterized using different ph.sicoch.m.cal studies as elem.ntal analysis, FT-IR, 1h.Nm., conductivity, m.gnetic properties, th.rm.l analysis, and th.ir biological activities. Th. spectroscopic data of th. com.lexes suggest th.ir 1:1 com.lexe structures wh.ch.are investigated by elem.ntal analysis, FT-IR, 1h.Nm., conductivity, m.gnetic properties, th.rm.l analysis, and th.ir biological activities. Th. spectroscopic studies suggested th. octah.dral structure for th. all com.lexes. Th. spectroscopic data of th. com.lexes suggest th.ir structure in wh.ch.(N2O2) group act as a tetradentate ligand and two ch.orides as m.nodentate ligands. Also electronic spectra and m.gnetic susceptibility m.asurem.nts indicate octah.dral structure of th.se com.lexes. Th. synth.sized Sch.ff base and its m.tal com.lexes also were screened for th.ir antibacterial and antifungal activity. h.re we report th. effect of a neutral ch.lating ligand on th. com.lexation with.iron to determ.ne it in different types of natural water using recovery test. Th. activity data sh.w th.t th. m.tal com.lexes to be m.re potent/ antibacterial th.n th. parent Sch.ff base ligand against one or m.re bacterial species.

Som. new pyridazinone derivatives(3) were synth.sized th.ough.addition of antipyrin to β- aroylacrylic acids (1) followed by cyclization of th. adducts. Reactions of 3 with.eth.l brom.acetate, benzenesulfonyl ch.oride, benzoyl ch.oride and POCl_3 give N-substituted products and m.noch.orosub- stituted pyridazines (4), respectively. Th. reactions of th. latter with.th.ourea give unexpected dith.o- derivatives(5), wh.ch.react with.ph.nylh.drazine to give pyrazolopyridazino pyridazine derivatives (6).

Introduction: Fluid resuscitation is th. cornerstone in th. m.nagem.nt of h.m.dynam.cally unstable patients. Dynam.c param.ters of fluid responsiveness, like pulse pressure variation, h.ve th. advantage of being m.re reliable index for fluid m.nagem.nt. Objective: Th. aim.of our study was to com.are between arterial pulse pressure variation (PPV) versus central venous pressure (CVP) as a predictor for fluid responsiveness during m.jor open abdom.nal operations. Patients and m.th.ds: 60 adult patients under general anesth.sia with.m.ch.nical ventilation underwent open m.jor abdom.nal surgical procedures were included in our prospective random.zed controlled study. Intravenous fluid was infused and m.nitored by CVP in control group or by PPV in th. oth.r group. h.m.dynam.c variables (h.art rate, invasive blood pressure, PPV and CVP) were m.asured at baseline after anesth.sia induction and every 10 m.n, during first h.ur of operation, and th.n every 15 m.n, till end of surgery. Blood loss and total i.v. fluid & blood transfusion given to patients were recorded and com.ared between two groups intraoperatively. Results: Patients in th. PPV group required m.re intraoperative fluid and blood transfusion th.n patients in CVP group to ach.eve m.re stable h.m.dynam.c param.ters. Th. fall in blood pressure (>20% of baseline) and increase in h.art rate are m.re com.on in CVP group (p Conclusion: PPV is a better predictor and a good guide for fluid responsiveness. m.re stable h.m.dynam.c variables are observed in PPV group.

Background: Im.roving th. quality of care in psych.atric settings is th. m.st im.ortant goal of policy th.ough.th. delivery of a com.reh.nsive care, treatm.nt, control, protection, and reh.bilitation of patients with.m.ntal disorders. Th. m.in concern in m.ntal h.alth.care is th. continuing use of seclusion and th. slow pace of ch.nge. Purpose: Analyze th. seclusion room.policy in National Center for m.ntal h.alth.(NCm.) in Jordan to recognize th. issue and present alternative solutions in order to m.dify and im.rove th. current seclusion room.policy. m.th.d: Th. auth.rs got seclusion room.policy from.NCm.;th. m.th.d in th.s analysis will be used six-step m.del;and th.n search.d th. database for alternatives using EBSCO, PUBm.D, m.DLINE, CINAh., and Ovid. Result: Th. auth.rs discuss use m.dications, training program. m.nipulate environm.nt, de-escalation tech.ique, and status quo alternatives th.t h.lps in m.nim.zing use of seclusion, decreasing th. incidence of aggressive beh.viors occurrences, and decreasing unsafe beh.viors against h.alth.care providers in th. psych.atric settings. Conclusion: m.nipulates environm.nt is th. best alternative after evaluated alternatives according to criteria.

A series of ch.m.cal com.osition based on Cr, Fe and O with.Zn as a partially substituting ion h.s been prepared in th. general form.la Zn//xCr//1// m.nus //xFe//2O by coprecipitation m.th.d using Nh./4Oh.as th. precipitating agent at ph.equals 10.3. Th. prepared sam.les were identified by both.th.rm.l analysis (DTA and TGA) and X-ray diffraction. It was found th.t no single ph.se is obtained for any of th. studied com.ositions but a m.xture of different ph.ses is observed, depending on th. m.lar percentage of zinc ion substitution as well as on th. sintering tem.erature. Th. tem.erature dependence of th. electrical conductivity, sigm. , of th. prepared sam.les is plotted between 25 and 680 degree C. It was observed th.t th. electrical conductivity increases with.tem.erature for both.sam.les with.x equals 0.00 and 0.80 Zn ion content wh.le it is nearly tem.erature independent for sam.les with.interm.diate Zn concentration x equals 0.2 and 0.5 m.l fraction. Th. activation energy, E//a, calculated from.th. linear relation, lg sigm. -1000/T for th. final m.xtures (sintered at 1300 degree C) was calculated. (Edited auth.r abstract) 16 Refs.
