ANALYSIS OF VARIOUS METAL IONS IN SOME MEDICINAL PLANTS USING ATOMIC ABSORPTION SPECTROPHOTOMETER
Y.L. Ramachandra*, C. Ashajyothi and Padmalatha S. Rai
International Journal of Pharmaceutical Sciences and Research , 2012,
Abstract: Metal ions such as iron , lead, copper, nickel, cadmium , chromium and zinc were investigated in medicinally important plants Alstonia scholaris, Tabernaemontana coronariae, Asparagus racemosus, Mimosa pudica, Leucas aspera and Adhatoda vasica applying atomic absorption spectrophotometer techniques. The purpose of this study was to standardize various metal ion Contamination in indigenous medicinal plants. Maximum concentration of lead was present in Leucas aspera and Adhatoda vasica followed by Alstonia scholaris, Tabernaemontana coronariae and Asparagus racemosus. The concentration of lead in Mimosa pudica was below the detectable level. The maximum concentration of zinc was detected in Adhatoda vasica followed by Leucas aspera, Asparagus racemosus, Tabernaemontana coronariae, Alstonia scholaris and Mimosa pudica. The concentration of Cadmium, nickel and chromium was below the detectable level.
In vitro antioxidant activity of Holarrhena antidysenterica Wall. methanolic leaf extract
P. S. Sujan Ganapathy,P. S. Sujan Ganapathy,Y. L. Ramachandra,S. Padmalatha Rai
Journal of Basic and Clinical Pharmacy , 2011,
Abstract: Antioxidative potential of methanolic leaf extract of Holarrhena antidysenterica was evaluated using hydroxyl radical, superoxide anion scavenging and reducing power assays. The antioxidant activity of the methanol extract increased in a concentration-dependent manner. The extract showed significant reactive oxygen species (ROS) scavenging activity in all in vitro antioxidant assays and contained high level of total phenolic content.
Phytochemical analysis and hepatoprotective properties of Tinospora cordifolia against carbon tetrachloride-induced hepatic damage in rats
B. T. Kavitha,S. D. Shruthi,S. Padmalatha Rai,Y. L. Ramachandra
Journal of Basic and Clinical Pharmacy , 2011,
Abstract: The present study was conducted to evaluate the hepatoprotective activity of different extracts of Tinospora cordifolia against carbon tetrachloride (CCl4) induced liver damage in rats. The pet ether, ethanol and aqueous extracts of various parts of the plant such as leaf, stem and root were tested at the dose of 200mg/kg body weight orally using Wistar albino rats and Silymarin was given as reference standard. Ethanolic extract of all the parts showed significant hepatoprotective effect by reduction in serum enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and total bilirubin (TBL) in the selected model which is followed by aqueous and pet ether extracts.The chemical constituents reported from the plant belong to different classes such as alkaloids, flavanoids, glycosides,steroids, terpenoids, phenolics and saponins. The overall experimental results suggests that the biologically active phytoconstituents such as flavonoids, alkaloids present in the ethanolic extract of plant Tinospora cordifolia, may be responsible for the significant hepatoprotective activity. Therefore, results justify the use of Tinospora cordifolia as a hepatoprotective agent.
MTHFR Gene variants C677T, A1298C and association with Down syndrome: A case-control study from South India
Cyril Cyrus,Rai Padmalatha,Chandra N,Gopinath P
Indian Journal of Human Genetics , 2009,
Abstract: Background: The 5,10-methylenetetrahydrofolate reductase ( MTHFR ) polymorphisms and low folate levels are associated with inhibition of DNA methyltransferase and consequently DNA hypomethylation. The expanding spectrum of common conditions linked with MTHFR polymorphisms includes certain adverse birth outcome, pregnancy complications, cancers, adult cardiovascular diseases and psychiatric disorders, with several of these associations remaining still controversial. Trisomy 21 or Down syndrome (DS) is the most common genetic cause of mental retardation. It stems predominantly from the failure of chromosome 21 to segregate normally during meiosis. Despite substantial research, the molecular mechanisms underlying non-disjunction leading to trisomy 21 are poorly understood. Materials and Methods: Two common variants C677T and A1298C of the MTHFR gene were screened in 36 parents with DS children and 60 healthy couples from Tamil Nadu and Karnataka. The MTHFR genotypes were studied by RFLP analysis of PCR-amplified products and confirmed by sequencing. Results: The CT genotype was seen in three each (8.3%) of case mothers and fathers. One case father showed TT genotype. All the control individuals exhibited the wild type CC genotype. A similar frequency for the uncommon allele C of the second polymorphism was recorded in case mothers (0.35) and fathers (0.37) in comparison with the control mothers (0.39) and fathers (0.37). Conclusion: This first report on MTHFR C677T and A1298C polymorphisms in trisomy 21 parents from south Indian population revealed that MTHFR 677CT polymorphism was associated with a risk for Down syndrome.

Utilization of Granite Powder as a Filler for Polybutylene Terepthalate Toughened Epoxy Resin  [PDF]
H. V. Ramakrishna, S. K Rai
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2006, DOI: 10.4236/jmmce.2006.51001
Abstract: Granite powder filled epoxy and polybutylene terephthalate (PBT) toughened epoxy composites were prepared. The variation of the mechanical properties such as tensile, flexural, compressive strengths and impact with filler content was evaluated. The effect of the silane coupling agent on the properties of these composites and the chemical resistance and water absorption of these composites was studied. The composites with 50% granite powder showed better properties.
Paediatric Surgical Outreach to Papua New Guinea: Initial Experience  [PDF]
R. Rai, Jack Mulu, A. S. Jacobsen
International Journal of Clinical Medicine (IJCM) , 2018, DOI: 10.4236/ijcm.2018.99058
Abstract: This is a report of our early experience in establishing a Paediatric surgical outreach program to Papua New Guinea (PNG) to build capacity and improve care. A Paediatric surgical outreach mission was initiated about 4 years ago in collaboration with Singhealth and PNG along with the multidisciplinary team of health care professionals from Cardiology, Cardiothoracic Surgery, Orthopaedics, Urology, Plastics and Anaesthesia. On each mission trip of 4 - 7 days duration, Singhealth doctors supervise or perform surgeries for complex cases, conduct patient consultations and give lectures to impart knowledge and transfer skills to the local health care community in PNG. In addition, a 6 - 12 months training program in Singapore for PNG doctors has been started. For complex cases which cannot be managed in PNG, there is provision for transfer of patients to Singapore under KKROK fund for further treatment. So far 4 mission trips have been conducted in past 4 years for paediatric surgical unit in Port Moresby General Hospital of PNG focussing on teaching and training of local Paediatric surgeons. Based on evaluation of the Singhealth medical team, there is severe shortage of medical manpower, surgical skill and specialised expertise. Due to lack of intensive care facility, adequate medications and proper medical equipment in the hospital, there are many conditions being left untreated causing high morbidity and mortality among infants and neonates. Such humanitarian work inspires Singhealth towards its global health mission of promoting health equity in responding to the medical needs of PNG through training and leveraging on strength through partnership. In addition, our doctors gain invaluable learning from the exposure, hone their skill as they treat a diversity of cases and are innovative in their treatment options by working in an environment with limited resources.

Ichthyosis follicularis with alopecia and photophobia (IFAP) syndrome
Rai Vandana,Shenoi S
Indian Journal of Dermatology, Venereology and Leprology , 2006,
Abstract: A 12-year-old boy born of a nonconsanguineous marriage presented with dry rough skin and photophobia since birth. His growth and developmental milestones were normal and there was no history of any neurological problem, hearing deficit or scarring around the hair follicles. Cutaneous examination revealed diffuse thinning of scalp hair with loss of eyebrows and eyelashes and a sandpapery texture of the skin all over the body, suggestive of ichthyosis follicularis with alopecia and photophobia syndrome.
