| 1 | Antibacterial activity of honey against clinical isolates of Escherichia coli,Pseudomonas aeruginosa and Salmonella enterica serovar Typhi显示文摘Objective:To ascertain the potential antibacterial activity of honey against clinical isolates of Escherichia coli(E.coli),Pseudomonas aeruginosa(P.aeruginosa) and Salmonella enterica serovar Typhi(S.enterica serovar Typhi) by in vitro methods.Methods:The partial inhibitory concentration(PIC),minimum inhibitory concentration(MIC) and minimum bactericidal concentration(MBC) values of the autoclaved honey(extracted from Apis indica hive by indigenous method) were determined for S.enterica serovar Typhi(n=8:from blood cultute), E.coli(n=5:from urine culture) and P.aeruginosa(n=5:from pus culture) isolates by in vitro methods.Results:The PICs of the honey tested for the isolates ranged 0.50%-1.25%(v/v) for S. enterica serovar Typhi,0.75%-1.50%(v/v) for E.coli and 1.00%-1.25%(v/v) for P.aeruginosa, while the MICs ranged 1.75%-3.00%(v/v),3.00%-3.50%(v/v) and 3.50%(v/v),respectively.The P.aeruginosa and E.coli isolates had MBC value of 4.00%(v/v):the S.enterica serovar Typhi showed MBCs in between 3.00%and 3.50%(v/v).The bactericidal activity of honey was achieved at concentration 3.00%(v/v) for S.enterica serovar Typhi and E.coli,and at 3.50%(v/v) for P. aeruginosa.Conclusions:The excellent antibacterial activity of honey against clinical bacterial isolates indicates the usefulness of honey in clinical practice against bacterial infection. | Shyamapada Mandal Manisha DebMandal Nishith Kumar Pal Krishnendu Saha | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，12： | 8 |
| 2 | Synergistic anti - Staphylococcus aureus activity of amoxicillin in combination with Emblica officinalis and Nymphae odorata extracts显示文摘Objective:To evaluate the antibacterial activity of Emblica officinalis Gaertn(E.officinalis: Family:Euphorbiaceae) seed and Nymphae odorala Aiton(N.odorala:Family:Nymphaeaceae) stamen extracts,alone and in combination,and in combination with amoxicillin(Ax) against Staphylococcus aureus(S.aureus).Methods:Antibacterial activity of ethanolic extracts of amla,E.officinalis,seed(AMS:500μg) and sapla,N.odorala,stamen(SAP:500 p g) for 12 methicillin-resistant S.aureus(MRSA) isolates was determined following agar diffusion:in order to assess the combined antibacterial activity,AMS(250μg) plus SAP(250μg) were considered.The Ax(10μg) activity alone and in combination with AMS(250μg),and SAP(250μg) was determined by disk diffusion.The zone diameters of inhibition(ZDIs) for the agents were recorded,and growth inhibitory indices(GIIs) were calculated.Results:The MRSA isolates (n=12) had AMS(500μg) and SAP(500μg) ZDIs of 12-19 mm and 21-24 mm,respectively.The ZDIs(range 24-27 mm) increased by 3-4 mm due to combined action of AMS(250μg) and SAP(250μg) indicating synergy between extracts for MRSA(GII 0.634-0.742).The MRSA isolates were resistant to Ax(ZDI:8-11 mm),which in combination with AMS and SAP had synergistic effect,both due to increased ZDI[mean±SD=(3.5±0.577) mm]and GII(0.631-0.894).Conclusions:The data suggest that the plants,E.officinalis and N.odorala alone or in combination,are promising in the development of phytomedicines,which may be used,alone or in combination with the antibiotic. Ax,against MRSA infection. | Shyamapada Mandal Manisha DebMandal Nishith Kumar Pal Krishnendu Saha | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 6 |
| 3 | Cholera:a great global concern显示文摘Cholera,caused by the infection of toxigenic Vibrio cholerae(V.cholerae) to humans,is a life threatening diarrheal disease with epidemic and pandemic potential.The V.cholerae,both 01 and 0139 serogroups,produce a potent enterotoxin(cholera toxin) responsible for the lethal symptoms of the disease.The O1 serogroup has two biotypes(phenotypes),classical and El Tor;each of which has two major serotypes(based on antigenic responses),Ogawa and Inaba and the extremely rare Hikojima.V.cholerae O1 strains interconvert and switch between the Ogawa and Inaba serotypes.Fluid and electrolyte replacement is the mainstay of treatment of cholera patients;the severe cases require antibiotic treatment to reduce the duration of illness and replacement of fluid intake.The antibiotic therapy cunenlly has faced difficulties due to the rapid emergence and spread o(multidrug resistant V.cholerae causing several outbreaks in the globe.Currently,cholera has been becoming endemic in an increasing number of geographical areas,reflecting a failure in implementation of control measures.However,the current safe oral vaccines lower the number of resistant infections and could thus represent an effective intervention measure to control antibiotic resistance in cholera.Overall,the priorities for cholera control remain public health interventions through improved drinking water,sanitation, surveillance and access to health care facilities,and lurther development of safe,effective and appropriate vaccines.Thus,this review describes the facts and phenomena related to the disease cholera,which is still a great threat mainly to the developing countries,and hence a grave global concern too. | Shyamapada Mandal Manisha Deb Mandal Nishith Kumar Pal | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，7： | 2 |
| 4 | Beaconless Position-based Routing with Guaranteed Delivery for Wireless Ad hoc and Sensor Networks显示文摘Existing position-based routing algorithms, where packets are forwarded in the geographic direction of the destination, normally require that the forwarding node should know the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages that each node sends out periodically. Several beaconless greedy routing schemes have been proposed recently. However, none of the existing beaconless schemes guarantee the delivery of packets. Moreover, they incur communication overhead by sending excessive control messages or by broadcasting data packets. In this paper, we describe how existing localized position based routing schemes that guarantee delivery can be made beaconless, while preserving the same routes. In our guaranteed delivery beaconless routing scheme, the next hop is selected through the use of control RTS/CTS messages and biased timeouts. In greedy mode, the neighbor closest to destination responds first. In recovery mode, nodes closer to the source will select shorter timeouts, so that other neighbors, overhearing CTS packets, can eliminate their own CTS packets if they realize that their link to the source is not part of Gabriel graph. Nodes also cancel their packets after receiving data message sent by source to the selected neighbor. We analyze the behavior of our scheme on our simulation environment assuming ideal MAC, following GOAFR+ and GFG routing schemes. Our results demonstrate low communication overhead in addition to guaranteed delivery. | CHAWLA Mohit GOEL Nishith KALAICHELVAN Kalai NAYAK Amiya STOJMENOVIC Ivan | 2006 | 自动化学报2006，32，6： | 2 |
