4. Anti-oxidative Effects and Toxicity of Bauhinia penicilliloba Ethanolic Leaf Extracts
This study aimed to investigate the anti-oxidative effect and toxicity of Bauhinia penicilliloba ethanolic leaf extracts (EEBP). The EEBP was 23.45% from dried weight which yielded active purified fraction (AFBP) at 1.84%. The AFBP was phytochemical screened and found to be flavonoid which identified as rutin, quercetin and kaempferol by using HPLC. The scavenging activity of EEBP and AFBP was examined by DPPH (IC50=12.91±0.11 and 5.55±0.23 μg/mL) and ABTS assays (TEAC=0.60±0.02 and 4.93±0.15 mM). The reducing power of EEBP and AFBP which were conducted by FRAP assay, was 0.61±0.09 and 8.68±0.15 mM/mg. The EEBP and AFBP also inhibited TBARS formation in brain tissue (IC50=13.58±3.25 and 6.07±0.74 μg/mL). The phenolic contents of EEBP and AFBP were 77.71±1.43 and 4,162.59±81.90 μg/mg of gallic acid equivalents. LD50 values for acute toxicity of a single intra-gastric (i.g.) route administered to adult male and female mice were >6.00 g/kg BW, whereas, LD50 values of intra-peritoneal (i.p.) route were >4.00 g/kg BW and 2.77 g/kg BW. Sub-chronic toxicity was conducted by given orally of the EEBP for 8 weeks. The body weight, organ weight, AST, ALT, ALP, Cr and BUN serum levels were not altered. Our study suggests that B. penicilliloba may have a considerable potential for further development as a new anti-oxidative agent.

5. Cyclodextrin-Based Formulations: A Non-Invasive Platform for Targeted Drug Delivery
Cyclodextrins (CDs) are recognized as promising pharmaceutical excipients due to their unique ability to form water-soluble inclusion complexes with various poorly soluble compounds. The numerous investigations on CDs and their use in nanomedicine have received considerable attention in the last three decades, leading to the rapid development of new CD-containing formulations that significantly facilitate targeted drug delivery and controlled drug release, with consequent improvements in drug bioavailability. This MiniReview highlights the efficacy and recent uses of CDs for non-invasive drug delivery. Using ophthalmic and nasal drug delivery as examples, an overview of chemical properties, mechanisms of CDs on drug solubilization, stabilization and permeation, along with their toxicological profiles relevant to nasal and ocular administration, are provided and discussed. The recent development and application of CD-based nanocarrier systems for targeted drug delivery are summarized.

Electrospun shellac nanofibers might be potentially used for wound dressing application due to its natural origin and excellent protective properties. In this study, a full factorial design with three replicated center points was performed in order to investigate the main and interaction effects of shellac content (35-40% w/w), applied voltage (9-27 kV) and flow rate (0.4-1.2 mL/hr) on the morphology of shellac nanofibers. A total of 11 experiments were conducted. The response variables were the diameter of nanofibers, the distribution of diameter and the amount of beads. The results showed that the concentration of shellac was the most significant impact on shellac nanofiber diameter, while applied voltage, interaction between shellac content and voltage, and feed rate were minor factors, respectively. Shellac content and applied voltage had negative relationships with bead amount. When reducing the concentration of shellac and voltage, the amount of beads was increased. However, the influence of these parameters on diameter distribution seemed to be not significant. Based on response surface plot, nanofibers with thinner diameter (-493 nm) and less number of beads (-0.47) could be obtained at the optimum conditions; the shellac content of 38.5% w/w, the voltage of 21 kV and the feed rate of0.4 mL/hr.

12. Development of bilayer zein-based matrix tablets for multiphasic drug release kinetics
Zein has been widely used as a film coating material for controlling the release of drug. However, the role as a matrix forming agent in tablets, especially the extended release dosage forms, was not clearly studied. The objectives of this study were to develop the bilayer tablets with multiple drug release kinetics, and to explore the effect of different zein contents on the mechanism of drug release from matrix tablets. Chlorpheniramine maleate was selected as a model drug. Matrix tablets with various amounts of zein were prepared as bilayer formulations by direct compression method. The first layer was designed for immediate release, and the second layer was aimed to provide a sustained release characteristic. Tableting properties including weight, thickness, diameter, friability, hardness and disintegration were evaluated. The dissolution assay was carried out in 0.1 N HC1 (pH 1.2), phosphate buffer solutions with pH of 5.5 and 7.0, respectively. The kinetics of drug release were analyzed using various mathematical models. The results suggested that weight, thickness, diameter, hardness and friability were not significantly different among formulations and well-controlled within the desired range indicating excellent tableting properties. An increase in the amount of zein led to the increased disintegration time exhibiting extended drug release. The first layer without zein component was completely disintegrated and dissolved within 10 min while the second layer consisting of several zein concentrations was not disintegrated. When 60%w/w or more of zein was used, the drug release profile seemed to be sustained over a period of 8 h as influencing by the gel barrier formation of zein after contacting with the aqueous media. The kinetics of drug release in 0.1 N HC1 and phosphate buffer solution pH 5.5 were fitted with Higuchi model, whereas the drug
release profile in pH 7.0 phosphate buffer solution was followed Hixson-Crowell model. Therefore, the main mechanisms of drug release in acid and basic media were Fickian’s diffusion and tablet erosion.

13. Topoisomerase I Inhibitory Activity and 3D QSAR Studies of Chromone Derivatives.
Topoisomerase I (Top I) is the molecular target for a diverse set of anticancer agents. This study was a continuation of previous work examining the Top I inhibitory activity of a series of chromone derivatives. Nine chromones were evaluated using eukaryotic DNA TOP I drug screening kit. The most potent inhibitor, chromone 20 showed greater inhibitory activity (IC50 = 0.83 mM) than the previously reported chromone compounds as well as the known Top I inhibitor, camptothecin. To develop the structure-Top I inhibitory activity relationship, the 3 dimensional quantitative structure-activity relationship (3D QSAR) were performed using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The best CoMFA model gave cross-validated r2 (q2) = 0.578 and non cross-validated r2 = 0.995 while CoMSIA gave q2 = 0.632, r2 = 0.996. The contour maps provide the fruitful structural features which are useful for designing new compounds with higher activity.

1. Solubility of Cyclodextrins and Drug/Cyclodextrin Complexes
Cyclodextrins (CDs), a group of oligosaccharides formed by glucose units bound together in a ring, show a promising ability to form complexes with drug molecules and improve their physicochemical properties without molecular modifications. The stoichiometry of drug/CD complexes is most frequently 1:1. However, natural CDs have a tendency to self-assemble and form aggregates in aqueous media. CD aggregation can limit their solubility. Through derivative formation, it is possible to enhance their solubility and complexation capacity, but this depends on the type of substituent and degree of substitution. Formation of water-soluble drug/CD complexes can increase drug permeation through biological membranes. To maximize drug permeation the amount of added CD into pharmaceutical preparation has to be optimized. However, solubility of CDs, especially that of natural CDs, is affected by the complex formation. The presence of pharmaceutical excipients, such as water-soluble polymers, preservatives, and surfactants, can influence the solubilizing abilities of CDs, but this depends on the excipients’ physicochemical properties. The competitive CD complexation of drugs and excipients has to be considered during formulation studies.

6. Investigation on the interactions between glucomannans and bifidobacterium protein by using molecular dynamics simulations
Konjac glucomannan is a polysaccharide extracted from the Amorphophallus konjac K.Koch plant. It is often used as food additives due to their low toxicity, biodegradability and low calories. The unique properties of konjac glucomannan is its prebiotic activities. Konjac glucomannan which cannot be digested and absorbed in human stomachs and small intestines. Therefore, it is fermented in the large intestine and becomes food for the beneficial bacteria or probiotics especially bifidobacteria and lactobacilli in human colons. This study examined the effect of the size of konjac glucomannan on the prebiotic property. The interactions between the different degrees of polymerization of konjac glucomannan and Bifidobacterium protein were investigated in 0.15 M sodium chloride solution at 310 K by using molecular dynamics simulation. The results have shown that water molecules dramatically affect the alignment of konjac glucomannan in the system. The active site of Bifidobacterium protein that determined by the calculations are composed of ASP154, ARG49, ASN206, and ASN401. The lowest flexibility of GM5 structure shows strong interactions with Bifidobacterium protein. The most suitable size of konjac glucomannan that can bind with the protein has the degrees of polymerization no more than 8.

7. Outcomes of Clinical Practice Guideline for Sepsis Patients in Taksin Hospital
Background: Sepsis is a serious disease with a high mortality rate.
Objective: To study the effect of a Clinical Practice Guideline [CPG] on mortality for sepsis patient management in Thailand.
Materials and Methods: The design was a retrospective study. The medical records of 472 severe sepsis or septic shock patients treated prior to and after the hospital sepsis CPG implementation in hospital were reviewed.
Results: Four hundred seventy-two patients were eligible for enrollment. The mortality rate was statistically significant different among studied patients in pre-implementation period (43.6%) and implementation period (13.1%) (p<0.001). There was statistically higher percentage of patients who received antibiotics within the first hours of being diagnosed with sepsis in implementation period (97.9%), compared with pre-implementation period (74.2%) (p<0.001). The significant higher numbers of patients in implementation period having enough volume replacement within the first six hours of severe sepsis or septic shock diagnosis compared with in pre-implementation period, as measured by an adequate urine output (≥0.5 ml/kg/hour) (84.6% versus 73.8%) (p = 0.018), and by an adequate central venous pressure (8 to 12 mmHg) (82.4% versus 43.3%) (p<0.001). In addition, there were significant difference in the percentages of patients having a reversal of septic shock in pre-implementation and implementation period (94.8% versus 88.4%) (p = 0.02). Conclusion: An implementation of the sepsis CPG in secondary-care hospital led to increase appropriate management and decrease mortality among the severe sepsis patients.
