STUDY OF ANTIULCER ACTIVITY OF ANGIOTENSIN RECEPTOR ANTAGONISTS IN EXPERIMENTALLY INDUCED GASTRIC ULCERS IN RATS
Background: Peptic ulcer is one of the common diseases affecting the mankind. Many studies reveal co-occurrence of both peptic ulcer and hypertension in humans. So, it might be beneficial to choose an optimal drug that will target both these conditions. The role of renin-angiotensin system in the pathogenesis of peptic ulcer is well known. AT receptor antagonists which prevent binding of AT-II to ...

PELLETIZATION OF LAMOTRIGINE SOLID DISPERSION FOR IMPROVED SOLUBILIZATION
Poorly solubility in water of many newly developed high-potential drugs is an obstacle in formulation development. The aim of this study was to increase the solubility of Lamotrigine which is a poorly soluble drug and comes under BCS class-II by using solid dispersion technique. Lamotrigine, PEG 4000 and PVPK-30 solid dispersion was prepared by solvent evaporation method and the formulation was ch...

VARIATIONS IN PHENOLICS, ANTIOXIDANT AND PHYTOCHEMICAL COMPOSITION OF SALVADORA PERSICA IN TWO LOCATIONS
Phenolic extracts of crude oil and methanol extracts of defatted seed cake were used to evaluate total phenolics, flavonoids content and antioxidant activity for two locations. The seeds were evaluated for their proximate composition while oils were subjected to chemical analysis. Salvadora persica had highest phenolics ranged from 12.3 ± 0.3 to 22.3 ± 0.3mg GAE/g and flavonoids content 3.7 ± 0...

DOUBLE LIPOSOMES MEDIATED DUAL THERAPY OF AIDS RELATED OPPORTUNISTIC FUNGAL INFECTIONS AND AIDS
To deliver zidovudine (AZT) to asialoglycoprotein receptors, drug-containing galactosylated liposomes were prepared. Simultaneously, miconazole nitrate (MCZ) was entrapped in the outer liposomal bilayer of double liposomes for the treatment of opportunistic fungal infections. Galactosylated liposomes were entrapped in double liposomes. The galactose binding Ricinus communis lectin was used for the...

SYNTHESIS, CHARACTERISATION AND BIOLOGICAL SCREENING OF Cu (II) COMPLEXES OF PINCER LIGANDS
The ligands bis-(benzimidazolyl)pyridine (BBIP) and bis-(benzimidazolyl)benzene (BBIB) have been used to synthesize Copper(II) complexes [Cu(BBIP)2]Cl2 and [Cu(BBIB)2]Cl2 respectively. The complexes are characterized by analytical and spectral (FTIR, 1H NMR and electronic) techniques. IR spectra of complexes show that the tertiary nitrogens in the ligand are involved in the co-ordination to the me...

ANTIDIABETIC ACTIVITY OF BARK AND ROOT OF CAESALPINIA BONDUE
The different extracts of the roots of Caesalpinia Bondue (Family- Fabeaccae) were tested for anti-diabetic activity, by glucose tolerance test in normal rats and alloxan induced diabetic rats. Aqueous ethanol and chloroform extracts had shown significant protection and lowered the blood glucose levels to normal in glucose tolerance test. In alloxan induced diabetic rats the maximum reduction in b...

COMPARATIVE STUDIES ON BIOCHEMICAL, HISTOPATHOLOGICAL AND FTIR-ATR SPECTRAL STUDIES OF HYPERLIPIDEMIA INDUCED BY CHOLESTEROL-RICH DIET IN RATS
Objective: To compare the routine biochemical and histological techniques with FTIR-ATR spectroscopic methods in diagnosing hyperlipidemia. Materials: Compositional changes in the serum and tissues reflects the healthy and pathological status of animals. FTIR-ATR was attempted as an additional tool for evaluating the composition in the serum as well as in tissues materials. To achieve this Wistar ...

MYELOPEROXIDASE AS A POTENTIAL BIOMARKER IN DIFFERENT STAGES OF KNEE OSTEOARTHRITIS
Osteoarthritis (OA) is disabling condition leading to loss of articular cartilage. Etiology of OA is not clearly understood and diagnosis of early stages of OA is difficult due to lack of specific markers. Recent literature suggest that elevation of Myeloperoxidase (MPO) levels in synovial fluid in early stages of OA as compared to controls and late stage OA. Presence of MPO in blood and Urine sam...

FATTY ACIDS OF HIPPOCRATEA AFRICANA ROOT: ANTIOXIDANT AND ANTI-MICROBIAL ACTIVITY
In this study, the fatty acid content, antioxidant activities and antimicrobial potential of oil obtained from the root of Hippocratea africana was investigated. Results showed that the oil was characterized by oleic acid (65.73%), palmitic acid (20.34%) and linoleic acid (6.90%) as the most abundant fatty acids with a oleic acid/linoleic acid ratio of 9.52. The oil possessed potent antioxidant ac...

ANTIOXIDANT POTENTIAL FRACTIONATION FROM METHANOL EXTRACT OF AERIAL PARTS OF RUELLIA PROSTRATA POIR (ACANTHACEAE)
Aerial parts of Ruellia prostrata were subjected to extraction and further fractionation to obtain antioxidant rich fraction. Different concentrations of methanolic extract and its n-butanolic fraction were subjected to antioxidant assay by DPPH method, Nitric oxide scavenging activity and reducing power assay. The fractions showed dose dependent free radical scavenging property in all the models....
