title: Cloning and characterization of platelet-aggregating proteins from trimeresurus albolabris venom

description: Crotaline venoms contain a variety of C-type lectin-like proteins that participate in hematotoxicity. Previously characterized lectins show conserved folds with several disulfide bridges. The structures are composed of alfa beta hetero-oligomers linked by interchain disulfide bonds. They may enhance or inhibit platelet-ligand bindings, as well as inhibition of clotting factor IX and X. In previous studies, the platelet glycoproteinIb-binding protein from trimeresurus albolabris named alboaggregin B (AL-B), has been purified and sequenced. However, there is no report of the cDNA sequences of AL-B. The aim of this thesis is to analyze the full-length sequence of AL-B alfa and beta subunits from the cDNA library of T. albolabris venom gland. Moreover the protein has been purified and characterized. Based on partial sequence of the primary library, oligonucleotide primers were designed and used to clone full-length cDNA encoding the C-type lectin subunit by 5'-RACE method. Additional homologous subunit was obtained using 3'-RACE. Analysis of the full-length nucleotide sequence found that the coding region of AL-B alfa subunit was 471 bp and beta subunit was 441 bp with the deduced protein sequence of 133 and 123 amino acid residues respectively, including 23 residues signal peptides. The nucleotide sequecne of AL-B alfa and beta subunit showed 85.25% and 79.45% amino acid sequence identity with stejaggregin from T. stejnegeri, respectively. In addition, by sequence comparison a conserved motif in AL -B beta (SRTY) that may be responsible for platelet aggregation activity was found. Furthermore, AL-B protein was purified from the snake venom and confirmed to be identical to the cloned protein using the MALDI TOF mass spectroscopy. AL-B agglutinated fixed human platelets with the EC50 of 180 nM and was completely inhibited by anti GPIb antibody. To our knowledge, this is the first report of cDNA cloning of C-typr lectin-like protein from T. albolabris.

title: Non-uniform bounds in normal approximation for matrix correlation statistics and idependent bounded random variables

description: This thesis contains two main parts. In the first part, let (a[subscript ij]) and (b[subscript ij]) be n x n matrices of real numbers and pi a random permutation of {1, 2, ...,n}. Under a boundedness condition, we establish non-uniform bounds in normal approximation for V and W by using a concentration inequality approach of Stein's method. In the second part, let X1, X2, ..., Xn be independent bounded random variables. We give a non-uniform bound in normal approximation for X1 + X2 +...+Xn by using Stein's method without using the concentration inequality approach.

title: The effect of interleukin-6 on the expression of receptor activater of NF[Kappa]B ligand, osteoprotegerin and microphage colony stimulating factor in human dental pulp fibroblast

description: Interleukin-6 (IL-6) is a highly pleiotropic cytokine that mediates the host inflammation and known to influence osteoclast formation and bone resorption. The aim of this study was to investigate the effects of IL-6 and combination of IL-6 and soluble IL-6 receptor (sIL -6R) on the expression of Receptor activator of NF kappa B ligand (RANKL), Osteoprotegerin (OPG) and Macrophage colony stimulating factor (M-CSF) in human dental pulp (HDP) cells cultures. Culture of HDP cells was established from the explant of pulp tissue. HDP cells were cultured in the presence of 0-10 ng/ml of IL-6. In another experiment sIL-6R ranging from 1-10 ng/ml was added in combination with IL-6. The expression of RANKL, M-CSF and OPG were determined using RT-PCR, western blot analyses an ELISA. Results indicated that IL-6 significantly increased RANKL expression at both mRNA and protein levels in dose-dependent manner but had no effect on the expression of M-CSF and OPG. IL-6+SIL-6 increased RANKL in mRNA level but had not affect on OPG and M-CSF and M-CSF expression. In contrast, RANKL and OPG protein were decreased following increased of SIL-6R. This study may lead to the implication that increasing IL-6 level in inflamed dental pulp may affect on mineralized tissue resorption due to the imbalance of RANKL/OPG system. Moreover, the combination of IL-6 and sIL-6R had decreased RANKL and OPG expression in protein level.

title: Cost-effectiveness analysis of dry powder inhaler and metered dose Inhaler with spacer in acute exacerbations of childhood asthma : a case study of King Chulalongkorn Memorial Hospital

description: The objective of this study was to analyse and compare the cost-effectiveness of the dry power inhaler (DPI) with the metered dose inhaler (MDI) and spacer for delivering salbutamol in the management of mild to moderate acute exacerbations of asthma in children aged 5 to 18 years. A retrospective analysis was performed based on clinical data form a multicenter, randomized clinical trial. King Chulalongkorn Memorial Hospital was chosen as the model for this economic evaluation A total of 80 patients with mild to moderate acute exacerbations of asthma were enrolled into the study, and followed up for 3 days. Equal number of patients (n = 40) were randomized to receive salbutamol administered via either the DPI or the MDI with spacer. The provider's and patient's perspectives were used to estimate costs of asthma treatment among patients. The total provider costs of delivering each treatment to the asthmatic patients was the sum of total routine service costs and total medical care costs. The total patient costs or total costs was calculated from the sum of total direct medical costs and total indirect costs. All costs in this study are presented in 2005 Baht. Outcome measures were the number and percentage of successfully treated patients at 60 minutes (defined as those with clinical scores reduce &gt;= 50% from baseline, or clinical scores &lt;= 3 as measured using the Modified Wood's Clinical Scores) There were not significant differences between the 2 treatment groups in the number and percentage of successfully treated patients, although there was a trend in favour of the DPI group compared with the MDI and spacer group (92.5% vs 90.0%). The means of total provider costs and total patient costs were also lower in the DPI group (Baht 180.98 vs Baht 239.63, and Baht 355.99 vs Baht 496.27, respectively), however, these differences were not statistically significant at 95% CI. The results from the cost-effectiveness analysis showed in favour of the DPI. This indicated that by switching to the DPI from the MDI with spacer, the costs for each additional percentage of successfully treated patients would be reduced by Baht 25.42 and Baht 60.79 according to the provider's and patient's perspectives, respectively. Sensitivity analysis demonstrated that these results were relatively robust over a wide range of assumptions.

title: Beta-lactam antibiotic resistant genes and genotypes of escherichia coli from clinical specimens

description: Thirty-seven extended spectrum beta-lactamase (ESBL) producing strains were detected among the 120 E. coli isolated from blood, pus, and urine of the patients at Siriraj Hospital during June to August 2004 using the National Committee for Clinical Laboratory Standards (NCCLS) initial screen test and the phenotypic confirmatory test. Antimicrobial susceptibility test of all ESBL producing E. coli strains were performed. Among the third generation cephalosporins, it was shown that all strains were resistant to cefpodoxime while these strains were more susceptible to ceftazidime (46.0%) than to cefotaxime (8.1%) and ceftriaxone (5.4%). For the other beta-lactam antibiotics, it was shown that 2.7% were susceptible to ampicillin, 10.8% to amoxicillin/clavulanic acid, 2.7% to cefazolin, 67.6% to cefoxitin, 19.0% to aztreonam, and 97.3% to imipenem. For non beta-lactam antibiotics, it was shown that 13.5% were susceptible to gentamicin, 32.4% to norfloxacin, and 27.0% to trimethoprim /sulfamethoxazole. The purified DNA from ESBL producing strains were also subjected for polymerase chain reaction (PCR) amplification of ESBL genes (bla [subscript TEM], bla [subscript SHV], bla[subscript CTX-M], and bla [subscript VEB] genes). Among 37 ESBL producing E. coli strains, 78.4% were bla [subscript TEM] positive, 8.1% were bla [subscript SHV] positive, 78.4% were bla [subscript CTX-M] positive, 8.1% were bla [subscript VEB] positive, and 75.7% were coharboured at least 2 different bla genes. As a result, the presence of bla [subscript TEM] and bla [subscript CTX-M] in ESBL producing E. coli strains indicates the high prevalence of these genes. All 120 E. coli strains were investigated for the presence of an integrase (intI1) gene which acts as the antimicrobial resistant genes carries to the other bacterial strains by PCR. Southern blot analysis using intI1 as a probe was also performed for all isolated DNA. As a result, as high as 99.2% of the strains carried intI1. This indicated the wild spread of resistant bacteria in Siriraj Hospital. There were 32 different pulsotypes among all 37 ESBL producing E. coli strains. The various different types indicated that horizontal gene transfer was more predominate than vertical gene transfer for the mode of antibiotic resistance transmission.

title: Cadmium distribution in stream sediment and suspended solids along Huai Mae Toa and Haui Mae Ku, Mae Sot District, Tak Province

description: This research was focused on distribution of cadmium in stream sediment and suspended solids from Huai Mae Tao and Huai Mae Ku creeks in Mae Sot District, Tak Province. The surrounding areas have been found cadmium contamination in paddy field and rice grain, besides cadmium was also detected in blood of local villagers. Moreover, the local economic is also threaten because rice cultivation had been prohibited by the government policy; consequently, compensation of hundreds million baht per year has to be paid to the farmers. Twenty eight stream sediment and eleven suspended solids samples with surrounding water samples were collected from Huai Mae Tao, Huai Mae Ku and Huai Nong Khieo (control site), before all samples were analyzed using ICP-OES for total cadmium and zinc concentrations. In addition, significant fractions of cadmium and zinc in stream sediment samples were determined using BCR Three-step; these fraction would give better idea to indicate potential cadmium impacting directly to the environment and human health. Analytical results show that soluble cadmium contents in all water samples are lower than the detection limit. Huai Mae Tao creek which is directly influenced by mining activities obtained the highest total cadmium and zinc concentrations in both stream sediment and suspended solids while Huai Nong Khieo creek yielded the lowest concentrations. Regarding sequential analyses, cadmiums in stream sediments from Huai Mae Tao contain mostly extractable forms (BRC1 and BRC2) which are very easily transferred into living organism; on the other hand, those from Huai Mae Ku are significantly characterized by BCR2 and final residual and those from Huai Nong Khieo are mainly in final residual form. It seems likely that sediments from Huai Mae Tao have more potential to effect the environment. In conclusion, Huai Mae Tao creek, closely related to zinc deposit, consequently contains high levels of total cadmium and zinc by natural processes (e.g. erosion and weathering) that are actually risky to agriculture, besides human activities may activate cadmium accumulation in the area. Apart form mining activity, agricultural processes would be taken into consideration for further discussion and subsequently protection and remediation plans. Eventually, it would lead to sustainable management of mineral resource and environment.

title: The Melaka Sultanate and its relationship with "Pirates"

description: This thesis attempts to study the relationship between the Melaka Sultanate and so-called "pirates" or Orang Laut in the pre-Portuguese period (15th-early 16th Centuries). They were known as a group of sea nomads who caught fish, roamed the seas, and had no permanent settlements. Moreover, what leads me to conduct this thesis was their reputation as "pirates" who robbed vessels sailing to the Straits of Melaka, the Riau-Lingga archipelago, and Singapore for trade. At the present, the Orang Laut is known as agroup of indigenous, almost primitive tribes, who has no status within many Southeast Asian nations. The Melaka Sultanate and the Orang Laut could co-exist. The prosperity of Melaka port was actually supported by the roles of the Orang Laut. Therefore, pre-European "pirates" and port relationships were not necessarily oppositional. In the case of the Melaka port and the Orang Laut, their relationship was symbiotic and constructive. This symbiotic relationship could be seen in many forms under the political, socio-economic contexts, and also regarding the security issue at that time.

title: Distribution of cadmium in laboratory-scale kale cultivation irrigated with cadmium contaminated water

description: To assess the cadmium distribution in soil, kale, and infiltrated water when irrigated with cadmium contaminated water at different concentrations. The sub objective was to assess crop safety under long term cultivation of kale. The irrigated water with eight cadmium concentrations: 0.010, 0.014, 0.023, 0.771, 1.291, 2.361, 5.531, and 7.982 mg/L were synthesized. Four rotations of kale (Brassica oleracea var. alboglaba) were consecutively grown in the same soil in eight laboratory-scale plot, diameter 1.0 m. and height 0.4 m. It was found that cadmium added was mainly adsorbed in soil while a small proportion absorbed in kale and infiltrated water. The infiltrated water had relatively low average cadmium concentrations 0.002-0.044 mg/L as compared with irrigated water. Based on Thailand drinking water standard, cadmium in irrigated water should not exceed 0.023 mg/L. The cadmium accumulation in kale was highest in root, stem, and leaf, respectively. The irrigated water with cadmium not exceeding of 0.023 mg/L is suggested based on crop safety (leaf and stem) of European Commission (EU) standard.

title: Foreign exchange rate risk and Thai stock market

description: To investigate how exchange rate returns effect return on investment in industries from the switching of exchange rate regime in June 2, 1997 that cause Asian economic crisis. The methodology is an unconditional two-factor model, estimated by Generalized Methods of Moments (GMM) to test the impact of bilateral exchange rate with three main traders (US, JP and EU) from 1992 to 2004. Moreover, this paper will explore another specification by extending the two-factor model. The first alternative is augmented with an interest rate spread factor. The second alternative specification is augment with two additional factors intendings to capture the effect of domestic interest rate and foreign interest rate. The results of the study show that there is no significant exchange rate coefficient in any currencies before the crisis in 1997. After the crisis, there are some sectors that are affected from domestic depreciation, some sectors benefit and some sectors suffer. The exchange rate risk is not significant in any currencies. A possible explanation is that the exchange rate risk is diversified across industries and/or across time. Extending two-factor model, additional explanatory variables are included to increase explanatory power. The results support robustness of using unconditional two-factor model.

title: Chromium removal by phytoremediation and biosorption

description: The possibility of using phytoremediation and biosorption with weed plant species in Thailand to remove chromium (Cr) from soil and water was investigated. Six plant species, Cynodon dactylon, Pluchea indica, Phyllanthus reticulatus, Echinochloa colonum, Vetiveria nemoralis and Amaranthus viridis, were chosen for their abilities to accumulate total chromium (TCr). TCr accumulation capacities of these plants were 152.1, 151.8, 101, 77, 69 and 0 mg/kg, respectively, at a hexavalent Cr[Cr(VI)] concentration of 100 mg Cr(VI)/kg soil. Within 30 days of dosing, Cr(VI) accumulation by Pluchea indica occurred mainly in roots, stems and leaves at 29, 35 and 73 mg/kg biomass on a dry weight basis, respectively, whereas 38, 18 and 0 mg/kg accumulated in the roots, stems and leaves of Cynodon dactylon, respectively. Biosorption experiments were conducted in both batch and column reactors. A synthetic solution containing 50 ppm of Cr(VI) was used to represent Cr(IV) contaminated water. Phyllanthus reticulates, Pluchea indica and Echinochloa colonum showed the maximum Cr(VI) adsorption capacities of 53, 45 and 37 mg/g biomass, respectively, at a pH of 2 and an equilibrium time of 24 hours. Leaves were found to have the maximum adsorption capacity. In the column experiments, leaves of Pluchea indica had the maximum Cr(VI) adsorption capacity of 51.3 mg/g biomass at a pH of 2, a breakthrough time of 102 hours, and a flow rate of 1.3 ml/min. The relationship of Cr removal capacities of phytoremediation with living plants and biosorption using non living biomass are discussed. Leaves of Pluchea indica had greater Cr(VI) accumulation and adsorption than the other plants and are therefore the most effective for Cr phytoremediation and biosorption.

title: Association of anti-double-strander DNA antibodies and disease activity measuremenr in systemic lupus erythematosus

description: Objective: To demonstrate the association between anti-double stranded DNA antibodies (anti-dsDNA Ab) and disease activity in systemic lupus erythematosus (SLE). Methods: A 1-year study of the association between anti-dsDNA Ab titer and the Mexican Systemic Lupus Erythematosus Disease Activity Index (MEX-SLEDAI) in patients with SLE was performed. Results: One hundred and seventy-three patients with SLE were included in the study. Positive anti-dsDNA Ab (anti-dsDNA Ab ≥1:10) were detected in 92 patients (53.2%) and negative anti-dsDNA Ab (anti-dsDNA Ab &lt; 1:10) were detected in 81 patients (46.8%). In positive Ab group, the mean age at inclusion was 32.4±10.3 years, with the mean disease duration of 5.3±5.7 years. In negative Ab group, the mean age at inclusion was 34.0±10.4 years, with the mean disease duration of 6.7±6.1years. Both positive and negative Ab groups were predominately female. Three patterns of disease activity index according to MEX-SLEDAI scoring system were observed: Nine patients (9.8%) in the positive Ab group and 28 patients (34.6%) in the negative Ab group had inactive disease. Twenty patients (21.7%) in the positive Ab group and 8 patients (9.9%) in the negative Ab group were classified as probably active disease. Sixty-three patients (68.5%) in the positive Ab group and 45 patients (55.6%) in the negative Ab group had clearly active disease (p&lt;0.001). Positive anti-dsDNA Ab was associated with several organ involvements: hematological 75% (p=0.011), mucocutaneous 40.2% (p=0.019) and musculoskeletal involvement 12.0% (p=0.047). However, this Ab was not related to renal manifestation (55.4%) in our study (p=0.426).Conclusions: Positive anti-dsDNA Ab is mostly correlated with disease activity in SLE patients whereas negative titer cannot totally exclude disease flare. Positive titer is associated with hematological, mucocutaneous and musculoskeletal involvement but it is not correlated with renal manifestation.
