Tirupathi Reddy Eevuri,Ramya Putturu
Veterinary World , 2013, DOI: 10.5455/vetworld.2013.172-179
Abstract: The importance and use of herbal remedies (turmeric, tulsi, amla and aloe vera etc.) has been reviewed systematically. Turmeric (curcumin), acts as an antioxidant, antimutagenic, antiinflamatory and antimicrobial agent and protect liver against a variety of toxicants. Tulsi (eugenol) have anticancer properties, reduced blood glucose levels, total cholesterol levels and promotes immune system function. Amla, richest source of vitamin-c and it's active tannoid principles have antimicrobial, antidiabetics, anticarcinogenic properties and enhances immune property. Aloe vera contains phytochemicals (Saponins, flavonoids, alkaloids and phenols), which is an indication of cosmetic and medicinal value. Turmeric, tulsi, amla and aloe vera preparations increased the body weight gain, feed efficiency and decreased the feed intake. These preparations decreased the mortality rates and the cost of feed has been decreased from 6.2% to 13.5%. They have reduced the fat accumulation, increased dressing percentage, liver weight, spleen weight and whole giblet weights. Significant reduction of serum cholesterol, serum triglycerides and increased the humoral response against RD vaccine. [Vet World 2013; 6(3.000): 172-179]

Putturu Ramya,Thirtham Madhavarao,Lakkineni Venkateswara Rao
Veterinary World , 2012, DOI: 10.5455/vetworld.2012.541-545
Abstract: Aim: To study the incidence of S.enteritidis in poultry and meat samples by cultural and PCR methods. Materials and Methods: A total of 130 samples (25 each of chicken, mutton, poultry faeces, cloacal samples and 10 each of liver, spleen and kidney) collected from different sources were subjected to cultural and PCR methods for the presence of Salmonella and Salmonella enteritidis. Primers for invA and sefA gene were used for Salmonella and S.enteritidis respectively. Results: Out of 130 samples, 87 were positive for Salmonella spp. i.e. chicken-16(64%), mutton-12(48%), faeces-23(92%), cloacal swabs-23(92%), liver-5(50%), spleen and kidney samples-4(40%) each by PCR methods, whereas 77 were positive by cultural method i.e. chicken-14(56%), mutton-10(40%), faeces-22(88%), cloacal swabs-21(84%), liver-4(40%), spleen and kidney-3(30% each). Out of 87 positive for Salmonella by PCR method, 59(chicken-12, mutton-7, faeces-17, cloacal swabs-15, liver-3, spleen-2, kidney-3) were positive for S.enteritidis. High incidence of S.enteritidis (68%) in all the above samples are indicative of unhygienic conditions in poultry farms. Selective enrichment with Rappaport-Vassilidias (RV) broths and Tetrathionate (TT) broths were superior over Selenite-F (SF) and Selenite cysteine (SC) broths. Conclusions: High incidence of S.enteritidis was seen in most of poultry samples like chicken, kidney, liver and it's faeces than mutton, which was indicative of contamination of S.enteritidis is more prevalent in poultry farms.

Veterinary World , 2013, DOI: 10.5455/vetworld.2013.185-188
Abstract: Aim: To test the sensitivity of S. Enteritidis for selected antibiotics. Materials and Methods: S. Enteritidis isolates obtained from different samples of chicken, mutton, turkey meat, faecal and cloacal samples of poultry and turkey, eggs, water and feed were subjected for sensitivity and resistance to selected antibiotics like- Chloramphenicol (30μg), Gentamicin (10 μg), Nalidixic Acid (30 μg), Tetracycline (30 μg), Ciprofloxacin (5 μg), Amikacin (30 μg), Amoxicillin (25 μg), Ampicillin (10 μg), Streptomycin (10 μg) and Sulfonamide (30 μg). Antimicrobial susceptibility of the isolates was established by the disk diffusion assay with MH (Muller-Hinton) agar in accordance with French National Antibiogram Committee Guidelines. Results: The sensitivity of S. Enteritidis was 100% for ciprofloxacin followed by chloramphenicol and amikacin (96%), gentamycin (90%), amoxicillin (82%), streptomycin (80%), tetracycline (76%), nalidixic acid (68%), ampicillin (58%) and sulfonamide (10%). The resistance was highest for sulfonamide (76%) followed by ampicillin (32%), nalidixic acid (30%) and 6-20% for gentamycin, amoxicillin and tetracycline. Conclusion: S. Enteritidis isolates were more sensitive to ciprofloxacin, chloramphenicol, amikacin, gentamycin, streptomycin,amoxicillin and tetracyclines and less sensitive to sulfonamides. Higher resistance was observed with sulfonamide followed by ampicillin and nalidixic acid. [Vet World 2013; 6(4.000): 185-188]
Genetic Variation in Picea mariana × P. rubens Hybrid Populations Assessed with ISSR and RAPD Markers  [PDF]
Ramya Narendrula, Kabwe Nkongolo
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.36088
Abstract: Interspecific hybridization can result in significant shifts in allele frequencies. The objective of the present study was to assess the level of genetic variation in populations of P. mariana × P. rubens hybrids derived from artificial crosses. Progenies from backcross populations created through a series of controlled pollinations among P. mariana and P. rubens trees across the hybridization index were analyzed. Several Inter Simple Sequence Repeat (ISSR) and Random Amplified Polymorphic DNA (RAPD) primers were used to amplify genomic DNA samples from each population. ISSR primers produced from 30% to 52% polymorphic loci. The level of polymorphism was higher with RAPD markers, ranging from 57% to 76%. Overall, the two marker systems generated similar levels of polymorphic loci for P. mariana and P. rubens populations. No significant differences were found among the P. mariana × P. rubens populations analyzed and between the hybrids and the parental populations regardless of the molecular marker used. This confirms the genetic closeness of P. mariana and P. rubens species.

Thanuja Pradeep, Ramya Marappa
Open Journal of Ophthalmology (OJOph) , 2016, DOI: 10.4236/ojoph.2016.62015
Abstract: Aim: We report a case of fungal keratitis and Ocular Surface Squalous Neoplasia (OSSN) occurring in a HIV positive patient. Method: A 32-year-old female patient presented with a non-healing ulcer, which was diagnosed as fungal keratitis. On examination her ocular surface also revealed OSSN on the nasal bulbar conjunctiva. Serological investigations revealed HIV positive status with CD 4 counts of 61 cells/μl. Patient was treated for fungal keratitis with topical antifungals and also underwent excision biopsy of OSSN which was reported as conjunctival intraepithelial neoplasia. The ulcer showed significant response to topical medication only after the commencement of Anti-Retroviral Therapy (ART). Conclusion: This case emphasizes on the importance of a thorough ocular examination to rule out associated ocular conditions and investigations to rule out immunosuppressive status in a non-healing ulcer.

Abstract: The study aims to find out the relationship between the socio-economic and the demographic characteristics of higher secondary students (N=559, male 311, female 248) residing in government hostels run by Adi-Dravidar Welfare Department in Tiruchirappalli district, Tamil Nadu. Out of 684 students, 559 students were selected from all 37 hostels by adopting census method. A self prepared questionnaire was used for collecting data in respect of socio-economic and demographic variables and an instrument on Study Habits and Attitude was used to find out the study habits of the respondents. The result shows that sex, caste, place of living, parents occupation, presence of alcoholic fathers, private tuition, school coaching and extra-curricular activities have significant influence on the study habits of the respondents. Further, the study shows that age, class, religion, course, school, birth order, parental education, income, marital status, type and size of family, have no significant influence on study habits of the respondents. An understanding of the socio-economic and the demographic characteristics of the respondents is very essential to develop good study habits of students residing in government welfare hostels.
Importance Of Aflatoxins In Scientific Sector
Ramya Muthukrishnan
Pharmaceutical Reviews , 2004,
Abstract: Aflatoxins are thefamily of mycotoxins that are related by the presenceof bisfurancoumarin compounds. They areprobably the best know and most intensively researched mycotoxinsin the world. They are named so because they were first isolated from thefungus Aspergillus flavus.Recent research has found out thar under specificconditions some strains of Aspergillus oryzae and Aspergillus parasiticus also have the ability to produce toxins. Theyare designated as B and G series because of their fluorescegreen yellow.The syndrome resulting from theingestion of aflatoxin through mold contaminated foodor feed is referred to as aflatoxicosis. The best wayto present aflatoxicosis is to present the infectionof the feed by Aspergillus. High CO2 levels alongwith decreased humidity have been shown to decrease aflatoxinlevels. The most effective and practical method of detoxification ofcontaminated food is ammoniation. This can kill up to99% of mold growth. A properdetoxification process must be technically and economically viable and mustmeet the following criteria.
