Cassia nodosa Bunch.is an ornamental tree belonging to family Leguminosae, popularly known as Pink Shower is a perennial tree. Laboratory evaluations were made to asses the study of primary metabolites in different plant parts of Cassia nodosa Bunch. The highest amount of soluble sugars (10.27mg/ gdw), lipids (32.36mg/gdw), phenols (20.0mg/gdw), DNA (11.78mg/gdw) and Chlorophyll- a+b (0.94mg/gdw) ...
Tridax procumbens L. is a well known medicinal plant. In the present study alkaloids from pedicle and buds of the plant were extracted and evaluated for antimicrobial activity by ‘Disc Diffusion Assay’ against selected bacteria (Escherichia coli, Staphylococcus aureus and Proteus mirabilis) and fungi (Aspergillus flavus, Aspergillus niger, Candida albicans and Trichophyton mentagrophytes). Min...
Tinospora cordifolia is known for a wide range of medicinal properties. In this study, cardiovascular and antimicrobial properties of aqueous and ethanolic extracts of Tinospora cordifolia were evaluated. Dose dependent negative ionotropic and chronotropic effects were observed with both aqueous and ethanolic extracts. The effects were antagonized by atropine indicating involvement of muscarinic r...
ORAL AND SYSTEMIC SIDE EFFECTS OF CANCER CHEMOTHERAPY AND EFFECT OF BENZYDAMINE MOUTHWASH IN ORAL MUCOSITIS
Aim: To check the effectiveness of 0.15% Benzydamine hydrochloride on oral mucositis secondary to cancer chemotherapy Methods: In the past few years, multiple cases were referred to our department for the management of oral manifestations of cancer chemotherapy for various malignancies. Out of these patients, we selected 5 patients and used a simple, inexpensive treatment modality in considerat...
Valsartan is an orally administered ACE inhibitor for the treatment of hypertension and cardiac failure, but its solubility and oral bioavailability are poor. The objective of investigation is to formulate a microemulsion drug delivery system of valsartan using minimum surfactant concentration that could improve its solubility and oral bioavailability. Valsartan microemulsion were prepared by ...
Non enzymatic glycation takes place when elevated levels of reduced sugars react with amino groups of proteins and is called as advanced glycation end products (AGEs) are responsible for Diabetes Mellitus. Hydroalcoholic extract of Whitton root (Eulophia nuda) was tested for in-vitro inhibition of non-enzymatic glycation of Immunoglobin G. Plant extracts have their own importance and now being s...
FORMULATION AND IN VITRO EVALUATION OF METOPROLOL SUCCINATE FLOATING TABLETS BY USING TWO VISCOSITY GRADE OF HPMC
Metoprolol is a beta1-selective (cardio selective) adrenergic receptor blocking agent used in the treatment of Hypertension. The purpose of this investigation is to improve bioavailability by preparing a gastroretentive drug delivery system. Floating tablets of Metoprolol Succinate were prepared by employing two different grades of HPMC K4M and HPMC E15M in different concentrations by effervescent...
SPECTROPHOTOMETRIC METHODS FOR SIMULTANEOUS ESTIMATION OF CEFUROXIME SODIUM AND SULBACTAM SODIUM IN INJECTON
Cefuroxime is a 2nd-generation cephalosporin and Sulbactam is a β-Lactamase inhibitor. The combination formulation is used for the treatment of lower respiratory tract infection. Two new, simple, accurate and precise UV spectrophotometric methods have been developed and validated for the simultaneous determination of Cefuroxime Sodium (CEF) and Sulbactam Sodium (SUL) in their combined dosage form...
AMELIORATIVE EFFECT OF HYGROPHILA AURICULATA (K. SCHUM) HEINE ON LIPID PEROXIDATION IN A RAT MODEL OF N-NITROSODIETHYLAMINE INDUCED HEPATOCELLULAR CARCINOMA
This study was designed to investigate the ameliorative effect effect of Hygrophila auriculata (H. auriculata) on lipid peroxidation (LPO) in N-nitrosodiethylamine induced Hepatocellular Carcinoma (HCC) in rats. Experimental rats were divided into different groups: normal, N-Nitrosodiethylamine induced hepatocellular Carcinoma bearing rats, H. auriculata treated hepatocellular carcinoma bearing ra...
NLC are innovative vehicles introduced to overcome some limitations of SLN. Particularly, NLC, composed of a solid lipid and a certain content of liquid lipid (oil), show improved drug entrapment efficiency and an increased stability during storage with respect to SLN. Furthermore, NLC, maintaining their solid state, can control the API release from the matrix. To formulate Nanostructure lipid car...
