Abstract:

        Thuja occidentalis is a monoecious coniferous plant belongs to the family cupressacae. It has high medicinal importance. In the present study, the antibacterial activity of hot water, cold water and Methanolic extracts of Thuja occidentalis leaves were tested against Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 74303, Staphylococcus aureus ATCC 6538, Enterobacter faecalis ATCC 35824, Salmonella typhi ATCC 14028, by Disk diffusion method. All tested bacterial organisms were susceptible to all the extracts showing zones of inhibition ranging from 6mm to 12mm in hot water extracts, 4mm to 9mm in cold water extracts and 5mm to 11mm in methanolic extracts. The result shows that Thuja occidentalis leaves have potential of antibacterial activity against all bacterial species mentioned in the study. The extracts showed significant results against different bacterial strains.

EXAMINATION FOR HEMAGGLUTINATION ACTIVITY OF NEWCASTLE DISEASE VIRUS ON CHICKEN ERYTHROCYTES UNDER DIFFERENT CONDITION

Author Name:  SHUJA and KANEEZ FATIMA*

Volume No : 1,  Issue No : 3,  Published year : 2014, Category : Biological Sciences

Abstract:

Newcastle disease (ND) is a serious disease of birds. ND virus (NDV) was analyzed by checking the hemagglutination activity (HA). The various factors like vaccine concentrations (0.5% and 1%), buffers (PBS and saline buffer), incubation temperature, incubation time and pH of saline and PBS buffer were varied and the effect of these factors on HA activity of NDV was observed. It was observed that the maximum HA activity was obtained at pH 7.4 and concentrated vaccine showed good activity as compared to diluted vaccine. Micro titer plates incubated at room temperature showed better HA activity.

DENTAL IMPLANTS AND NANOTECHNOLOGY

Author Name:  PARNEET SOFAT et al.,

Volume No : 1,  Issue No : 3,  Published year : 2014, Category : Biological Sciences
Abstract:
Nanotechnology is one the current fields of interest to adjust the properties of implants. It deals with systems and structures that result in new properties due to their small size (1-100 nm). The main applications in the bio-materials science are controlled cell attachment on different implant surfaces and design of multi-functional drug delivery device. Because the cell attachment depends both on surface chemistry and on the surface nano-scale features, the modification of implants involves usually different surface treatments. The aim of this paper is to review the various aspects of interaction of implants with stem cells, osseo-integration of dental implants and dental implant surface modifications.

Abstract:

        FicusCarica plant is traditionally used in curing many ailments. In the present study, aqueous and ethanolic extracts of Ficus carica leaves were tested for their antibacterial activity against Escherichia coli, Salmonella typhimurium and Staphylococcus aureus. Leaves were prepared using cold water, hot water and ethanol as solvents. Anti microbial activity was determined using well diffusion method. The results showed that the Hot water, Cold water and Ethanolic extract show antibacterial activity but the zone of inhibition against Staphylococus aureus was higher. Comparing the types of Extracts, Ethanolic extract showed higher antibacterial activity and the maximum zone of inhibition against Staphylococcus aureus was. These results indicate the significance of F.carica plant in pharmacognosy and need further study to quantify the antimicrobial agents and their chemistry.
