Abstract
Background: Argyreia nervosa (Convolvulaceae) plant is an example of hallucinogenic plant. The antiseptic, anti-inflammatory, antispasmodic, antibacterial, antiviral, antifungal, anticonvulsant, nootropic, antifertility and aphrodisiac properties have already been reported for this plant. Aim: The aim of present work was to evaluate the wound healing property in normal and diabetic animals by oral and topical administration of ethanolic extract of leaves. Materials and Methods: Phytochemical investigations showed the presence of various biochemicals (alkaloids, flavonoids, carbohydrates, triterpenoids, proteins, saponins, steroids, tannins). A single injection of alloxan monohydrate (120 mg/kg, i.p.) prepared in citrate buffer (0.1 M, pH 4.5) was administered to produce diabetes in rats and mice, after overnight fasting. Excision wounds (sized 300 mm2 and of 2 mm depth) were used for the study of rate of contraction of wound and epithelization. The means of wound area measurement between groups at different time intervalswere compared using one-way analysis of variance (ANOVA), followed by Dunnet's test. Results: Extracts of A. nervosa showed significant wound healing effect in normal (topically treated) and diabetic (both topically and orally treated) rats. In diabetic rats, the topically treated group showed more significant effect than the orally treated groups. Conclusion: The present study demonstrates that A. nervosa leaves extract applied topically promotes healing of wounds more significantly as compared to oral application, in both normal rats and alloxan induced diabetic rats, where healing is otherwise delayed.

Abstract
The growth and stability of salt-water clusters have been experimentally studied in aqueous solutions of NaCl, KCl, and NH(4)Cl from dilute to near-saturation conditions employing dynamic light scattering and zeta potential measurements. In order to examine cluster stability, the changes in the cluster sizes were monitored as a function of temperature. Compared to the other cases, the average size of NaCl-water clusters remained almost constant over the studied temperature range of 20-70 °C. Information obtained from the temperature-dependent solution compressibility (determined from speed of sound and density measurements), multinuclear NMR ((1)H, (17)O, (35)Cl NMR), and FTIR were utilized to explain the cluster behavior. Comparison of NMR chemical shifts of saturated salt solutions with solid-state NMR data of pure salts, and evaluation of spectral modifications in the OH stretch region of saturated salt solutions as compared to that of pure water, provided important clues on ion pair-water interactions and water structure in the clusters. The high stability and temperature independence of the cluster sizes in aqueous NaCl shed light on the temperature invariance of its solubility.

Abstract
OBJECTIVES Multiple randomised trials have demonstrated lower perioperative mortality after endovascular aneurysm repair (EVAR) compared to open surgical repair for infrarenal abdominal aortic aneurysms (AAAs). However, in these trials the mortality advantage for EVAR is being lost within 2 years of repair and the patients evaluated are relatively older with no study specifically comparing EVAR and open repair for patients younger than 60 years of age. DESIGN A retrospective analysis of prospectively collected data. MATERIALS AND METHODS Patients younger than 60 years of age who underwent EVAR and open surgical repair for elective infrarenal AAA were identified from the 2007-09 National Surgical Quality Improvement Program (NSQIP) - a prospective database maintained at 237 centres across the United States. Univariate and multivariate analyses were performed. RESULTS Of the 651 patients, 369 (56.7%) underwent EVAR and 282 (43.3%) underwent open repair. Thirty-day mortality for EVAR and open repair were 1.1% and 0.4%, respectively. This was not significantly different on univariate (P = 0.22) as well as multivariate (P = 0.69) analysis after controlling for other co-morbidities. On multivariate analysis, body mass index, history of stroke and bleeding disorder prior to surgery were associated with a higher 30-day mortality after AAA repair (combined open and EVAR). CONCLUSIONS These contemporary results demonstrate that the 30-day mortality rate after open repair is similar to that after EVAR in patients younger than 60 years with infrarenal AAA.

Abstract
A pH mediated in situ gelling system was developed using prilocaine hydrochloride for periodontal anesthesia using combination of chitosan and hydroxypropylmethylcellulose. The gel so developed can be used as anaesthetic in lengthy dental surgery. The gel was evaluated for many parameters like gelation pH, viscosity, physicochemical properties, in vitro release, sterility and stability. Gel with chitosan (0.25% w/v) and hydroxypropylmethylcellulose (0.25% w/v) was found to have good gelation near pH 7.4 (pH of mucous) with prolonged action.

Abstract
The use of local antibiotics from a biodegradable implant for chronic osteomyelitis is an attractive alternative. The implant delivers high antibiotic concentration at tissue levels, obliterates dead space, aids bone repair and does not need to be removed. The purpose of this paper is to develop and evaluate a calcium sulphate and polycaprolactone based composite biodegradable implantable delivery system of cefoperazone sodium. Implants were prepared by modified fabrication technique to avoid solvent use. Interaction studies were carried out to check any incompatibility between ingredients. Prepared implants were evaluated for various in vitro parameters like dimensions, hardness, tensile strength, drug release profile and sterility. Morphological changes in pellet before and after drug release were evaluated by scanning electron microscopy. The pellet were also tested for microbiological efficacy and compared with plain drug solution in different concentrations. Developed pellets are regular in shape and size with good tensile strength. The release profile displayed drug levels above MIC continuously up to 2 months. Wide zone of inhibition by pellet against Staph. aureus as compared to drug solution proves its efficacy in treatment of osteomyelitis.

Abstract
This study compared the efficacy and tolerability of an optimized botanical combination containing policosanol, tomato extract, orally bioavailable grape procyanidins and Oenothera biennis oil against placebo in the management of patients with primary hypercholesterolemia and mixed dyslipidemia. Such a combination is endowed with biological properties targeted to cholesterol control and vasoprotection. This randomized, double-blind, parallel-group trial consisted of a 6 week treatment period following 4 week baseline period, and a 2 week post-treatment follow-up. At baseline, both the groups were comparable to each other. Both the active treatment and the placebo group included 30 patients (active treatment: mean age 46.80 ± 7.43 years, nine males; placebo: mean age 45.50 ± 6.76 years, eight males). Significant reductions in the LDL-cholesterol (LDL-C; -17.33% from baseline, p < 0.001) and total cholesterol (TC; -13.38% from baseline, p < 0.0001) values over the treatment period were observed with the tested product. The treatment also resulted in reductions in C-reactive protein (CRP), malondialdehyde (MDA) and superoxide dismutase (SOD) values, which are indices of oxidative stress. This rational combination of different compounds is effective and safe in lowering the elevated LDL-C and TC values. It is also effective in the modulation of the oxidation indices values; however, a further long term study in a larger population would be needed in order to confirm these preliminary findings.
