Curcumin Mediated Gold Nanoparticles and Analysis of its Antioxidant, Anti-inflammatory, Antimicrobial Activity Against Oral Pathogens

Objective: To green synthesise gold nanoparticles using curcumin and to analyse its antioxidant, anti-inflammatory, and antimicrobial activity among oral pathogens. Material and Methods: Biosynthesised Curcumin Gold nanoparticles (CuAuNP) were evaluated by UV-visible spectrophotometer (UV-Vis), Transmission Electron Microscopy (TEM), and evaluation of antioxidant, anti-inflammatory and antibacterial activity against oral pathogens. Results: Synthesized CuAuNP were characterized using UV-visible spectrophotometry and showed peak absorption at 530nm. CuAuNp showed a 90.3% maximum scavenging ability of DPPH at a concentration of 50 μg/mL. CuAuNP exhibited 79.6 % of the highest anti-inflammatory activity at 50μg/mL than the standard drug diclofenac. TEM image clearly showed uniformly dispersed spherical-shaped gold nanoparticles with a size of about 20 nm. The biosynthesized nanoparticle was tested for its antimicrobial effect, and it showed a potent effect against S. aureus, E. faecalis, and C. albicans at 100µg/ mL. Enterococcus faecalis has a maximum zone of inhibition of 14 mm at 100µg/ mL of CuAuNp. Among gram-positive bacteria, a maximum zone of inhibition of 12 mm at 100µg/ mL was seen in S. aureus compared to S mutans. Candida albicans showed a maximum zone of inhibition of 18 mm at 25 μg/mL of CuAuNp. Conclusion: Curcumin-mediated gold nanoparticles with 20 nm size were effective and had strong antioxidant and anti-inflammatory activity at 50µg/ mL, antimicrobial action inhibiting microbes at 100µg/ mL concentration that can be used in treating various Oral mucosal lesions

A Study to Evaluate the Effectiveness of Planned Teaching Programme on Prevention and Control of Malaria among Mothers at Karattuppalayam under Tiruchengodu Taluk, Namakkal District, Tamil Nadu

OBJECTIVES: 1. To assess the knowledge of mothers regarding Prevention and control of malaria before administering teaching programme. 2. To develop and administer Planned teaching programme on Prevention and control of malaria. 3. To find out the effectiveness of Planned teaching programme in improving the knowledge of mothers by post test. 4. To compare the pretest and post test knowledge score of mothers on prevention and control of malaria. 5. To explore the relationship between pretest knowledge scores with selected demographic variables like age, education, occupation, type of family, family income, method of water storage and drainage system. The conceptual framework adopted for this study was based on Stuffle Beams Evaluation Model. The research approach adopted for this study was quasiexperimental approach. The research design selected for this study was one group pre test, post test, which was used to measure the effectiveness of planned teaching programme. The selection of mothers was done by simple random sampling technique and the sample consists of 50 mothers in Karattuppalayam area, Tiruchengodu Taluk, Namakkal District. The instrument developed and used for this present study was semi-structured interview schedule, which had two parts. Part I: Comprised of 17 items related to socio demographic variables. Part II: Comprised of Section A: Comprised of 10 items related to knowledge of malaria. Section B: Comprised of 24 items related to prevention and control of malaria. The study was conducted during the month of December 2010, the collected data were analysed by using descriptive and inferential statistics in terms of frequencies, percentages, mean, SD, t-test and chi-square test. MAJOR FINDINGS: In the present study, majority of them were between 26-35 yrs and all are hindus and educated.58% of the mothers were house wives and 38% had the monthly income between 4001-6000.Among 50 mothers 38% of them belonged to nuclear family.12% of the mothers had the previous history of malaria in the family. The post test mean score percentage (77.4%) on prevention and control of malaria were comparatively more than their pre-test knowledge score 32.88%.It confirms that ,there was increase in knowledge after administration of planned teaching programme. The paired `t’ test analysis of the pre and post test knowledge t=34.253(P<0.05) was highly significant. This result evidently supports the effectiveness of planned teaching programme on prevention and control of malaria. The present study also reveals that, there is a significant association between the score on prevention and control of malaria with selected socio demographic variables like age, income, occupation, method of water storage, type of drainage and previous history of malaria. RECOMMENDATIONS: 1. The study can be replicated by using a larger sample there by findings can be generalized. 2. Comparative study may be conducted to find out similarities or difference in knowledge between urban and rural communities. 3. A study may be conducted to identify the factors which influence the spread of malaria among the people in the community. 4. A longitudinal study can be done among the public on the prevention and control of malaria. 5. Mass and individual regional language health education campaign can be conducted

Assessment of Maximum Bite Force in Oral Submucous Fibrosis Patients: A Preliminary Study

Objective: To determine the maximum bite force (MBF) in oral submucous fibrosis (OSMF) patients and to compare them with that of healthy subjects. Material and Methods: Twenty patients who were clinically confirmed, as OSMF and 20 healthy controls matched for age, gender, and number of intact functional teeth were included in this study. For each subject, age, gender, weight, height and body mass index (BMI) were recorded. The MBF registration was carried out by the two evaluators, who were previously calibrated. Bite force was measured in the first molar region using a force transducer occlusal force meter for each subject seated at the upright position, with Frankfort's plane nearly parallel to the floor, and no head support. The Student’s independent t-test was used to determine the statistical significance in relation to mean height, weight, BMI and the presence of number of intact teeth and MBF between the healthy subjects and OSMF individuals. A comparison of grades of OSMF with all variables was carried out by one-way ANOVA test. Results: No significant difference was found in mean age, mean height, weight, BMI and the presence of the number of intact teeth between healthy individuals and OSMF patients. The mean MBF in healthy subjects was 628.23 ± 24.39 N and 635.47 ± 31.22 N in OSMF patients. Even though the healthy subjects reported a higher MBF than OSMF patients did, the difference was statistically non-significant. With regards to sides, no significant difference was observed in mean MBF in healthy subjects and OSMF patients on the right (p=0.7818) and left side (p=0.6154). Conclusion: The healthy subjects reported higher MBF values than OSMF patients did and the difference was statistically non-significant

AEROBIOLOGY OF MULBERRY FIELDS IN VELLORE DISTRICT

ABSTRACT Mulberry which forms the exclusive source of food for commercial silk producing silk worm (Bombyx mori L.) is affected by a number of diseases and pests. The aerobiology of crop field was very limited and much of the fields were to be opened for investigation. It affects the nutrition, growth and cocoon production of silkworm. Hence a detailed investigation was carried out on the aerobiology of mulberry fields in Vellore district. The Vellore district comprises of eight taluks, 14 ranges and 64 subdivisions. Much of the Vellore district land area is cultivated by Mulberry as a cottage industry. It is found that from October to January rainfall was maximum, Vaniyambadi, Tirupattur and Gudiyattam receives maximum rain. The humidity is relatively maximum during the period of October to September 1999. The temperature was maximum from March to June. This helps for the spread and growth of various microflora and airspores in Vellore district environs. From these data, the causative organisms of various diseases of Mulberry were identified. This data will be helpful for the treatment, management of the much useful plant Mulberry in Vellore district
