Objective: This study was designed for Screening of anti-inflammatory and anti-analgesic activity of ethanolic extract of Convolvulus pluricaulis Choisy in various animal experimental models. Material and Methods: Ethanolic extract of Convolvulus pluricaulis Choisy evaluated for anti-inflammatory activity in Carrageenan-induced paw edema, Cotton pellet-induced granuloma model. The anti-analgesic activity was evaluated by Hot Plate Method and Tail-Flick Assay. Result: Administration of the ethanolic extract of Convolvulus pluricaulis Choisy at dose of 800 mg/kg p.o. showed significant (P < 0.001) inhibition of rat paw edema. The analgesic activity was determined on Wistar albino rats by hot plate method, tail flick assay using Morphine sulphate as standard drug at a dose of 5 mg/kg of body weight and the results were expressed as mean increase in latency after drug administration ± SEM. Conclusion: This study shows that ethanolic extract of Convolvulus pluricaulis Choisy has significant anti-inflammatory and anti-analgesic...

A series of new 1H-benzo[d]imidazole derivatives of 3, 4-substituted triazole. 3-(1H-Benzo[d]imidazol-2-ylsulfanyl) methyl-4-[phenyloxy(phenylacetamido)]-5-mercapto-1,2,4-triazole and related aryloxy compounds were synthesised, analysed and characterised by FTIR, 1HNMR and elemental analysis. These compounds were screened for antibacterial and antifungal activity. The antibacterial activities were compared against chlorophenicol and antifungal activity with mycostalin. Some triazole derivatives showed a little antibacterial but appreciable antifungal...

Diabetes mellitus is a metabolic syndrome involving severe insulin dysfunction in conjugation with gross abnormalities in glucose homeostasis and lipid metabolism, which has been affecting several millions of population all over the world. Despite the introduction of hypoglycemic agents from natural as well as synthetic sources, diabetes and its secondary complications continue to be a major health problem for the medical fraternity. Sesbania grandiflora L. Pers. is an Indian medicinal plant which belongs to family Leguminosae possesses a wide array of beneficial and pharmacological properties. In the present study an attempt has been made to evaluate the antidiabetic and antioxidant nature of Sesbania grandiflora leaves. Diabetes was induced by single intraperitoneal injection of streptozotocin (45mg/Kg b.wt). Diabetic rats orally treated with leaves extract ( 300 mg/kg b.w/day) for 30 days resulted in significant (p<0.05) decrease in the levels of blood glucose, glycosylated hemoglobin, blood urea, serum uric acid, serum creatinine and diminished activities of pathophysiological enzymes such as aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP). The...

Solvent evaporation technique is used for the preparation of Polylactic acid microspheres loaded with two antibiotics, Doxycycline and Tetracycline, by introducing different masses for each drug. They are characterized by calculation of drug encapsulation and drug loading, measuring the particle size, examining microspheres morphology, and performing FT-IR, stability and in vitro drug release studies. Moderate drug encapsulation values (38% and 24%) are observed for Doxycycline and Tetracycline respectively. Microspheres of both drugs show homogeneous size distribution varying between 80 and 110 µm. the FT-IR study has helped in verifying that both Doxycycline and the polymer are intact after microencapsulation. In the case of Tetracycline, it hasn’t revealed any significant results due to the low loading values. After 6 months of storage at different conditions, no appreciable difference is observed concerning the degradation of microspheres. In vitro release of drugs from encapsulated Polylactic acid microspheres shows that Tetracycline release is slightly faster and reaches 98% in less than 5 hours, in comparison with Doxycycline which attains the same percentage after...

Rhizophora mucronata Lam. belongs to mangrove plants and antidiabetic activity is one of the traditional uses of R. mucronata. One of the anti-diabetic therapeutic strategies is inhibition of carbohydrate digesting enzymes such as alpha-amylase and alpha-glucosidase. Hence in the present study, 2 extract namely, aqueous and ethanol of Rhizophora mucronata Lam. were evaluated for their effect on alpha-amylase and alpha-glucosidase enzymes using in vitro assays. Ethanol extract showed the highest alpha-glucosidase inhibitory activity (IC50= 9.45 µg/ml) than aqueous extract. Ethanol extract inhibited the enzyme more potently than the standard acarbose. Further, the antioxidant activity of extracts was monitored using DPPH assay, whereas, phenolic content was estimated using Folin-Ciocalteu reagent. The alpha-glucosidase inhibitory activity of R. mucronata correlated to antioxidant activity and phenolic content of extracts. However, these extracts showed no alpha-amylase inhibitory effect. Besides, R. mucronata has shown anti-HIV potential in our previous study. Oxidative stress and anti-HIV drugs are associated with diabetes. Our current and previous studies thus report anti-diabetic, antioxidant and anti-HIV activities of R....
