Abstract Inflammatory bowel disease (IBD) is classified into ulcerative colitis and Crohn's disease. It is chronic inflammation of gastrointestinal tract and idiopathic disease. Sugar is proved to be risk factor for IBD. Calorie restriction is a nutrition intervention to reduce energy intake and can reduce chronic desease. This study aims to determine the difference in the effect of a high-calorie diet and calorie restriction on intestinal inflammation. Eight-week-old healthy female Balb/c mice were divided into two groups. The high calorie (HC) group was fed standard diet plus oral gavage of glucose solution every day for 4 weeks. The dose of glucose solution was 0.0325 ml/gBW or 3-5% additional calories each day. The calorie restriction (CR) group had their calorie intake restricted to 50% of standard diet 3 times a week. After 4 weeks of treatment, the mice had their colon removed. The assessment of the intestinal inflammation was carried out using a light microscope, with a scoring system by Erben et al (2014) in HE staining. The mean score of the HC group was 1.22, this was higher than the CR group with a mean score of 1.18 even tough the result revealed that the scores of intestinal inflammation were not significantly different in the two groups (P = 0.827). However, there is no evidence for the underlying mechanism of intestinal inflammation by high-calorie diet and improvement of intestinal inflammation in high-calorie diet via calorie restriction. Thus, further research is needed on other calorie restriction methods in high-calorie diet study. Keywords: High calorie diet, Calorie restriction, Intestinal inflammation
摘要炎症性肠病分为溃疡性结肠炎和克罗恩病。它是胃肠道的慢性炎症和特发性疾病。糖被证明是IBD的危险因素。热量限制是一种减少能量摄入的营养干预措施,可以减少慢性疾病。本研究旨在确定高热量饮食和限制热量摄入对肠道炎症影响的差异。将8周龄的健康雌性Balb/c小鼠分为两组。高热量(HC)组每天喂食标准饮食加口服葡萄糖溶液,持续4周。葡萄糖溶液的剂量为0.0325ml/gBW或每天3-5%的额外热量。热量限制(CR)组每周3次将热量摄入限制在标准饮食的50%以内。治疗4周后,小鼠的结肠被切除。使用光学显微镜和Erben等人(2014)的HE染色评分系统对肠道炎症进行评估。HC组的平均得分为1.22,高于CR组的平均分1.18。结果显示,两组的肠道炎症得分没有显著差异(P=0.827)。然而,没有证据表明高热量饮食引起肠道炎症的潜在机制,也没有证据表明通过热量限制改善高热量饮食中的肠道炎症。因此,在高热量饮食研究中,还需要对其他热量限制方法进行进一步的研究。关键词:高热量饮食,热量限制,肠道炎症

Abstract Stroke is a leading cause of death in Thailand. However, there are varying numbers of regional stroke patients. This study aims to report the ranking of stroke as the cause of death in Northern Thai cadavers and to investigate the brains of stroke victim cadavers. A retrograde study was used to obtain data about cadavers and gross examinations were performed on the brains of the stroke victim cadavers housed in the Department of Anatomy, Faculty of Medicine, Chiang Mai University in the years 2019-2020. The results showed that death from stroke among the cadavers in the Northern Thailand increased during 2016-2018. Stroke was ranked as the fourth and fifth leading cause of death. The stroke victims were primarily aged over 60 years. The incidence of stroke in males was significantly higher than that of females. Approximately 92.7% of total stroke brains were the intracerebral hemorrhagic type stroke. About 41.7% of the intracerebral hemorrhagic brains had occurred with intraventricular hemorrhage and 16.7% of those occurred with subarachnoid hemorrhage. The hemorrhagic sizes varied from 5.66 to 260.43 ml. The territories of the cortical branches of the middle cerebral artery were the most common hemorrhages, making up 22.9% of total vascular territories. In conclusion, stroke was the fourth and fifth leading cause of death in the self-donated population in the Northern Thailand. Intracerebral hemorrhagic stroke was the main cause the death. Additionally, the vascular territories of the stroke might be related to the likelihood of death. Keywords: Stroke, Cerebrovascular disease, Cadavers, Intracerebral hemorrhage, Northern Thailand
中风是泰国的主要死亡原因。然而,区域性中风患者的数量各不相同。本研究的目的是报告中风作为泰国北部尸体死亡原因的排名,并调查中风受害者尸体的大脑。采用逆行研究方法获取尸体数据,并对2019-2020年清迈大学医学院解剖学系的中风受害者尸体的大脑进行了粗略检查。结果显示,在2016-2018年期间,泰国北部的尸体死于中风的人数有所增加。中风被列为第四和第五大死因。中风患者主要年龄在60岁以上。男性中风的发病率明显高于女性。大约92.7%的脑卒中患者为脑出血型脑卒中。脑室内出血占脑出血的41.7%,蛛网膜下腔出血占16.7%。出血大小在5.66 ~ 260.43 ml之间,以大脑中动脉皮层分支出血最为常见,占血管总出血面积的22.9%。总之,中风是泰国北部自我捐献人口死亡的第四大和第五大原因。颅内出血性中风是主要死因。此外,中风的血管范围可能与死亡的可能性有关。关键词:中风,脑血管疾病,尸体,脑出血,泰国北部

Abstract Inflammation is a phase of the wound healing process that occurs after tooth extraction which is influenced by the immune system. Lymphocytes are one type of cell in the immune system that have an important role in the inflammation process. The purpose of this study was to investigate the effect of Pangasius djambal gelatin treatment on the enhancing lymphocyte cell count after tooth extraction in Rattus norvegicus. In this study, the in vivo true experimental laboratories with a post-test group design was maintained. In this study, we performed 3 control groups without treatment by the Pangasius djambal gelatin and 3 treatment groups with 100 mg/mL Pangasius djambal gelatin on the post-extraction wound of the mandibular left lateral incisor of Rattus norvegicus. Each group consists of 5 rats. The lymphocyte cells count in the tooth socket tissue was evaluated on days 3, 5, and 7. The control groups' lymphocyte cells count decreased significantly from 32 to 17.2 from day 3 to day 7. Interestingly, the lymphocyte cells of treatment groups increased from 92.2 to 114.6 from day 3 to day 7. Furthermore, a very strong positive correlation between the observation time and lymphocyte cell count was observed in this work (r = 0.838; very strong). Therefore, the Pangasius djambal gelatin opens new potency to increase the lymphocyte cells count after tooth extraction.

Abstract Protected areas have been developed in Thailand to conserve the natural environment required for wildlife and human beings, and to prevent disasters. It is necessary to address doubts about effectiveness of protected areas because regulations have been changed or are ignored in some communities and regions, especially in Chiang Mai province, which is facing the loss of natural forest areas under area transformations. Therefore, it is necessary to evaluate the effectiveness of forest protected areas. To do this, this study focused on analyzing multi-year land cover changes in Chiang Mai over two decades (1995-2015) with four land cover types: forest, agriculture, urban, and water bodies, inside and outside protected areas. The results suggest that the establishment of forest protected areas assisted to curtail urban expansion compared to non-protected areas. The protected areas effectively kept the number of divided forest patches small, and the forest patches were larger than in non-protected areas. We detected clearing of forests in protected areas, where they were transformed into agricultural areas. However, agricultural patches in protected areas were smaller and in higher densities than in non-protected areas. We conclude that the main contribution of forest cover loss in Chiang Mai is transition to agricultural areas, and that designated national parks and wildlife sanctuaries could help to effectively conserve such forest areas. Keywords: Land cover change, Land transformation, Protected areas, Non-protected areas, Geographic Information Systems (GIS)
泰国已经开发了保护区,以保护野生动物和人类所需的自然环境,并防止灾害。有必要解决对保护区有效性的质疑,因为一些社区和地区的法规已经改变或被忽视,特别是在清迈省,该地区正面临着地区转型下天然林面积的损失。因此,有必要对森林保护区的有效性进行评价。为此,本研究重点分析了清迈20多年来(1995-2015)的土地覆盖变化,包括四种土地覆盖类型:森林、农业、城市和水体、保护区内外。结果表明,与非保护区相比,森林保护区的建立有助于抑制城市扩张。保护区有效地保持了森林斑块数量较小,而森林斑块数量大于非保护区。我们发现保护区的森林被砍伐、被改造为农业区。然而,保护区内的农业斑块比非保护区面积小,密度高。我们的结论是,清迈森林覆盖损失的主要原因是向农业区的过渡,而指定的国家公园和野生动物保护区可以帮助有效地保护这些林区。关键词:土地覆被变化,土地改造,保护区,非保护区,地理信息系统

Abstract Sesame and perilla seeds were analyzed for fat, protein, moisture and ash. Their mineral contents, lignan, γ-tocopherol and fatty acid profiles were also determined. The results showed that sesame seeds had higher protein, lipid and mineral contents but lower fiber contents than perilla seeds, accounting for 17.38-20.76%, 42.70-46.18%, 3.07-6.47%, 18.00-21.88%, respectively. Major minerals in the seed were 0.26-0.95% calcium and 0.11-0.23% magnesium. Perilla oil showed lower pH than sesame oil giving it higher acid value. Most lignans were more concentrated in sesame than perilla. Sesamin was the predominant lignin, followed by sesamolin. The sesamin and sesamolin contents in sesame were ranged for 148.30-183.68 mg/100g and 33.96-43.54 mg/100g, respectively. Although black sesame oil had low content of sesamin and sesamolin, it performed high physiological functions due to its high contents of γ-tocopherol and unsaturated fatty acid. Gamma tocopherol of the oils was ranged from 35.81 to 51.64 mg/100g, and perilla oil showed the highest γ-tocopherol content. Fatty acid profiles revealed that the major fatty acids in sesame oils were 44.43-47.21% linoleic followed by 36.40-38.39% oleic, 7.07-9.64% palmitic and 5.09-7.72% stearic acids, giving them high polyunsaturated fatty acids (PUFA), followed by monounsaturated fatty acids (MUFA) and saturated fatty acids (SFA). White sesame oil had higher linoleic acid but lower oleic acid than other sesame oils. Perilla oil contained high amounts of 55.27% α-linolenic followed by 19.75% linoleic, 12.70% oleic and 7.38% plamitic acids, giving it high PUFA, but low SFA and MUFA. Keywords: Chemical composition, Minerals, Fatty acid profiles, Lignans, Gamma-tocopherol
摘要对芝麻和紫苏种子的脂肪、蛋白质、水分和灰分进行了分析。还测定了它们的矿物质含量、木脂素、γ-生育酚和脂肪酸图谱。结果表明,芝麻的蛋白质、脂肪和矿物质含量高于紫苏,但纤维含量低于紫苏,分别为17.38-20.76%、42.70-46.18%、3.07-6.47%、18.00-21.88%。种子中主要矿物为0.26-0.95%的钙和0.11-0.23%的镁。紫苏油显示出比芝麻油更低的pH值,使其具有更高的酸值。大多数木脂素在芝麻中的浓度高于紫苏。芝麻素是主要的木质素,其次是芝麻素。芝麻中芝麻素和芝麻素的含量分别为148.30-183.68mg/100g和33.96-43.54mg/100g。黑芝麻油虽然芝麻素和芝麻素含量较低,但由于其γ-生育酚和不饱和脂肪酸含量较高,具有较高的生理功能。γ-生育酚含量在35.81~51.64mg/100g之间,紫苏油的γ-生育醇含量最高。脂肪酸图谱显示,芝麻油中的主要脂肪酸为44.43-47.21%的亚油酸,其次是36.40-38.39%的油酸、7.07-9.64%的棕榈酸和5.09-7.72%的硬脂酸,使其具有高的多不饱和脂肪酸(PUFA),其次是单不饱和脂肪酸酯(MUFA)和饱和脂肪酸。白芝麻油的亚油酸含量较高,但油酸含量较低。紫苏油含有55.27%的α-亚麻酸,其次是19.75%的亚油酸、12.70%的油酸和7.38%的亚麻酸,使其PUFA高,但SFA和MUFA低。关键词:化学成分,矿物,脂肪酸图谱,木质素,γ-生育酚

Abstract In 2020, more than 70% of vaginal discharge complaints were pathological among Indonesian adolescent girls. Analyzing of the risk factors for pathological vaginal discharge could be the first step in leukorrhea prevention. The level of physical activity and vaginal hygiene behavior were factors potentially associate to the event of pathological leukorrhea. It was uncertain whether the level of physical activity or vaginal hygiene behavior be the risk factor of pathological leukorrhea. This study was aimed to investigate the main risk factor of pathological leukorrhea among female who are active in sports. This study was cross-sectional design among 70 students of Sport Program in Surabaya. The subject was randomly obtained and characterized for the level of physical activity and vaginal hygiene behavior, such as the frequency of panties replacement, panties material, urinary hygiene, vaginal soap/antiseptic, and panty liners utilization. The relationship was determined using Chi-square test. The relationship found between the event of pathological leukorrhea only with urinary hygiene (p-value 0.007).

Abstract Microwave heat treatment is one of the most widely used starch physical modification techniques in analyzing the increase in resistant starch levels in foodstuffs. However, this technique has varying effects on each type of high-carbohydrate food. This study aims to analyze the type of carbohydrate food that significantly increases the levels of resistant starch and prebiotic properties by the microwave heat treatment technique. This study used 31 articles that were analyzed and selected through the PRISMA guide method from 11.232 selected libraries. Secondary data will be analyzed based on the percentage of Effect Size Hedges'd (standardized mean difference/SMD) and confidence interval (CI) values using OpenMEE software. The meta-analysis results showed that the microwave heat treatment method on high-carbohydrate foods had a significant effect on increasing levels of resistant starch and prebiotic properties (SMD 2.755; 95% CI: 2.106 to 3.403; P <0.001). Based on the meta-analysis results, it can be concluded that the microwave heat treatment technology has a significant effect with a 95% confidence level in increasing levels of resistant starch and prebiotic properties in high-carbohydrate foods. Keywords: High carbohydrate foods, Meta-analysis, Microwave heat treatment, Prebiotic properties, Resistant starch

Abstract Indonesia is rich in eel (Anguilla spp.) fishery resources, however, only sparse information is available regarding these resources, particularly the habitat preferences. These preferences have been studied severally using different methods, thus, there is currently no comprehensive description of the exact study methods. This study, therefore, aims to assay the development of research on eel habitat in the tropics, especially in Indonesia, and discover the most prevalent study method used between 2001 and 2020. This was carried out using a systematic literature review, defined as the process of identifying, assessing, and interpreting all available research evidence to provide answers to specific research questions. A total of 21 studies were selected for further analysis based on the specified inclusion and exclusion criteria. According to the results, current studies on eel habitat preferences focus on three topics: the ecology and behavior of eels during their lifecycle (52%), the relationship between eel morphology and habitat (19%), as well as the relationship between the time of metamorphosis and habitat (29%). Furthermore, 4 methods: Bio-morphology (29%), Otolith (57%), Ecological Studies (10%), and Gonadosomathic Index (5%), are commonly used. However, researchers suggest future research ought to be conducted more comprehensively. Therefore, more detailed ecological studies need to be carried out, together with otolith and bio-morphological studies. Keywords: Systematic Literature Review, eels, habitat, and methodology preference for eel habitat
摘要印度尼西亚拥有丰富的鳗鱼(安圭拉属)渔业资源,然而,关于这些资源,特别是栖息地偏好的信息很少。这些偏好已经分别使用不同的方法进行了研究,因此,目前还没有对确切的研究方法进行全面的描述。因此,这项研究旨在分析热带地区,特别是印度尼西亚鳗鱼栖息地研究的进展,并发现2001年至2020年间使用的最普遍的研究方法。这是使用系统的文献综述进行的,定义为识别、评估和解释所有可用的研究证据,以提供特定研究问题的答案的过程。根据指定的纳入和排除标准,共选择了21项研究进行进一步分析。根据研究结果,目前对鳗鱼栖息地偏好的研究主要集中在三个主题上:鳗鱼在其生命周期中的生态和行为(52%)、鳗鱼形态与栖息地之间的关系(19%)以及变态时间和栖息地之间的关系(29%)。此外,常用4种方法:生物形态学(29%)、耳石学(57%)、生态学研究(10%)和性腺厚度指数(5%)。然而,研究人员建议,未来的研究应该更加全面。因此,需要进行更详细的生态学研究,以及耳石和生物形态学研究。关键词:系统文献综述,鳗鱼,栖息地,鳗鱼栖息地的方法论偏好

Abstract Sarawak had around 62% forest area coverage in 2018, contributed 40% of forest area in Malaysia. Two million hectares of licensed forest area was designated as Industrial Timber Production Areas (ITPAs) to sustain industrial timber production. Neolamarckia cadamba was one of the tropical indigenous timber species selected for the development of ITPAs. The selection is based on its local environment adaptation, pest and disease resistance, fast growing properties, soil maintenance contributions, its wood quality suitable for plywood industry. Tropical soils are infamous for poor plant available nutrients profile, contributed by high precipitation rate in tropical climate and acidic soil orders. Plant growth promoting microorganisms in wild environment would be a feasible solution for N. cadamba planting activities. Such studies on N. cadamba were limited whilst drafting this review paper. Nonetheless, potential strains, i.e Nitrogen fixing microorganisms, phosphate solubilising microorganisms and potassium solubilising microorganisms, were discussed. They could potentially provide three major plant available nutrients. For industrial production, their processing with solid, liquid or solid-liquid integrated carrier materials would provide long shelf-life, better survivability in the field and easy handling in different application strategies. Keywords: Biofertilisers, Neolamarckia cadamba, plant growth promoting microorganisms, Malaysia, tropical soils
沙捞越在2018年的森林面积覆盖率约为62%,占马来西亚森林面积的40%。200万公顷的许可林区被指定为工业木材生产区,以维持工业木材生产。卡丹巴(neolamarchkia cadamba)是开发itpa所选择的热带本地木材树种之一。选用的依据是其对当地环境的适应性、抗病虫害、快速生长的特性、对土壤的维护贡献,其木材品质适合胶合板行业。热带土壤是由于热带气候的高降水率和酸性土壤阶导致的植物有效养分分布差而臭名昭著。促进植物生长的微生物在野生环境中可能是一种可行的解决方案。在撰写这篇综述论文的时候,这类研究是有限的。然而,潜在的菌株,即固氮微生物,磷酸盐增溶微生物和钾增溶微生物进行了讨论。它们可能提供三种主要的植物可用营养物质。在工业生产中,用固体、液体或固-液集成载体材料处理它们,可以提供更长的保质期,更好的野外生存能力,并且在不同的应用策略下易于处理。关键词:生物肥料,新竹,植物生长促进微生物,马来西亚,热带土壤

Abstract The present study aimed to investigate clavulanic acid susceptible peptide spectra in 174 community-acquired urinary tract infected Escherichia coli isolates using VITEK® MS. They were collected from bacteriuria samples at Diagnostic Laboratory Unit between January and May 2016. One hundred and fourteen multidrug resistant isolates were detected. Among these isolates, 13, 53, and 48 isolates were classified as the non, high, and low ESBL-producers, respectively by using Epsilometer strip test. Spectrum analysis was calculated for investigating the enzyme spectrum. The mass analysis and spectrum identification of ESBL-producing isolates were elucidated using the VITEK® MS apparatus. Among 58 peptide spectra, seven E. coli-specific spectra located at 3126, 3433, 6317, 6411, 7159, 9537, and 10301 Dalton (Da) were commonly detected in ≥ 85% of the total samples. Among the high ESBL-producing isolates, the spectrum intensity of four ceftazidime-resistant spectra which were located at 4613, 5613, 6508, 9713 Da was significantly increased after being exposed to ceftazidime as the ceftazidime-resistant spectra. Using agar disk diffusion, four clavulanic acid-susceptible spectra, 3433, 4613, 4768, and 9713 Da, were significantly detected after being co-exposed to ceftazidime and amoxicillin/clavulanic acid. Interestingly, the spectrum intensity of the significant spectrum, 9713 Da, was decreased after being co-exposed to ceftazidime plus clavulanic acid using an Epsilometer strip test. The interesting peptide spectra at 9713 Da significantly exhibited the clavulanic acid-susceptibility after being co-exposed to ceftazidime and clavulanic acid in both assays and could be suspected to be the ESBL indicative peptide spectra in the high ESBL-producing isolates.
