Antibacterial activity of the two honey samples produced by the honey bee (Apis florea), was standardized by Disc diffusion method. The two honey samples were tested at three concentrations (5, 10 and 15µl v/v) and zone of inhibition were measured against Staphylococcus aureus, Escherichia coli, Basillus subitis, Pseudomonas putida and Klebsiela pneumonia; unifloral and multifloral honey samples were effected in inhibiting the growth of the gram positive and Gram negative organisms at (15 µl v/v). The inhibitory effect of unifloral honey on (15µl) Staphylococcus aureus and Escherichia coli; and multi floral honey on E.coli were comparable to that of Amphicillin (10µg/10µl). In conclusion, natural honey can be employed in treating, some common diseases especially those caused by the tested microorganisms and carry the potential of introducing new template into modern medicinal...

By using five different sieve sizes of ascorbic acid granules, affects of granule sizes on tablet properties, i.e. tablet weight and hardness have been studied with standard methods. Affects of lubricant types and concentrations on tablet properties, i.e. tablet hardness and disintegration time have also been studied by using magnesium stearate and sodium stearyl fumarate as the lubricants for producing tablets from mixed sizes granules of ascorbic acid. Moreover, affects of high, moderate or medium and low compression forces on tablet hardness and disintegration time have been studied by using the mixed sizes granules of ascorbic acid. The result reveals that medium sized granules are better than smaller or larger granules to produce tablets within the specificity. Tablet weight variation has been found as higher during the production of tablets from smaller or larger granules. Production of tablets without lubricants has been complicated due to the difficulties in tablet ejection, resulting in picking, sticking, capping and cracking of tablets, higher tablet hardness and lower disintegration time. With increasing concentration...

Endophytic fungi are ubiquitous in nature residing inside all the plant species contributing to their host plants by producing a plenty of substances that provide protection and survival value to the plant. Many researchers have proven that endophytes are a new and potential source of novel natural products for exploitation in modern medicine. This present study is undertaken to isolate and identify the potential endophytic fungi from Moringa olifera, a medicinal plants which is traditionally known and reported to posses various biological properties. A total of 72 fragments each 18 from the stem, leaves, flower and calyx were collected, surface sterilized and was inoculated on to Sabouraud dextrose agar (SDA) plates. Based on the macroscopic & microscopic features, the fungal isolates were identified.The most predominant endophytic fungal species isolated belonged to the genus Aspergillus spp. (53.3%) followed by Bipolaris spp. (6.6%). The Colonization Frequency (CF %) and Endophytic Infection Rate (EIR %) was found to be 83.31% and 20.83% respectively. The stem segments showed a maximum repository for endophytic...

Complexs of Fe, Cu and Zn have been prepared by reacting metal chloride\sulphate with p-hydroxyacetophenone thiosemicarbazone, p-fluoroacetophenone thiosemicarbazone, p-bromoacetophenone thiosemicarbazone as ligands and their complexes were screened for their IR, NMR, and antifungal and antibacterial studies. . Acetophenone thiosemicarbazone ligands were prepared by the reaction of substituted acetophenone with thiosemicarbazone in the presence of hot ethanol. All the transition-ligands 1:2 complexes have been isolated in the solid state, are stable in air, and characterized on the basis of their elemental and spectral data. They were found to be active against influenza, protozoa, small pox, and certain kinds of tumor. Their metal complexes were used, in various biological systems, polymers, dyes, anti-inflammatory, analgesic and anti-oxidative action. The Schiff bases and their metal complexes were used in various biological activities such as antimicrobial, antifungal, antiviral, insecticides, and antitumor...

The acute dental abscess is frequently underestimated in terms of its morbidity and mortality. The risk of potentially serious consequences arising from the spread of a dental abscess is still relevant today with many hospital admissions for dental sepsis. Acacia nilotica was commonly known in India as Babul has a wide range of medicinal uses. In the present study antibacterial activity of different parts of Acacia nilotica was studied to evaluate their potential for being used as natural antibacterial agent against various dental infections. The bioactivity Acacia nilotica was analyzed crude extracts of bark, leaves, and Pod of Acacia nilotica against five dental pathogens (Lactobacillus acidophilus, Streptococcus sanguinis, Streptococcus salivarius, Aggregatibacter actinomycetemcomitans) using agar diffusion technique and determine the minimum inhibitory concentration of each extract against the dental pathogen. The present study conducted to evaluate the highest anti dental infection property of different extract of Acacia nilotica. In this study the pod extract shows highest antibacterial potential followed by the bark extract and leaves...
