Authors: Okayasu Juriya
Published: August 2021

A new Old World genus in the tribe Trogaspidiini Bischoff, 1920, Arkaditillagen. nov., is described based on male morphology. Six species are recognized in this genus: A. bagrada (Cameron, 1902), comb. nov. (Indonesia, Malaysia), A. depressicornis (Mickel, 1935), comb. nov. (Malaysia), A. frimsp. nov. (Malaysia), A. gibbasp. nov. (Indonesia), A. lelejisp. nov. (Indonesia), and A. nallinia (Zavattari, 1914), comb. nov. (Indonesia). The species of this new genus were formerly placed in the genus Krombeinidia Lelej, 1996, but they are differentiated from it and other genera by having a unique set of morphological character states, such as the mandible inner margin expanded, forming subbasal tooth; the paramere antero-ventrally serrate; and the digitus dorsal margin lamellate. A key to species of Arkaditilla is provided.

The larvae of black soldier fly (Hermetia illucens L.) (BSFL) is an excellent decomposer for industrial and agricultural applications capable of converting low-value waste into nutritional biomass. Sesame residues is industrial food waste possess high protein and lipid content. To investigate the bioconversion process of BSFL, the larvae were raised on a low-bioburden diet consisting of sesame residue, and liquid chromatography-mass spectrometry (LC-MS) analysis was performed on the BSFL and faeces at various instars. The obtained metabolomes were subsequently evaluated through principal component analysis and orthogonal projection to latent structure-discriminant analysis to explore the differential components. Diacylglycerol was the main component of the sesame residues utilised by BSFL during metabolism. The phenylalanine, arginine, oleic acid and 10-hydroxy-8E-octadecenoic acid were identified as the major components in various instars of the BSFL metabolites. We thus concluded that BSFL have different nutritional compositions at different instar stages. Another compound with a molecular weight of 278.224 prevalent in both the larvae and faeces might play vital roles in BSFL development. The present study revealed a part of metabolic changes important in the BSFL lifecycle. Through this pioneering metabolomics profiles, the discovery of highly-valuable biomolecules on BSFL for food industrial application can be anticipated.
Digital Mixed Content Analysis on Digital Platform Social Data
Authors: Punziano Gabriella
Published: August 2021

The explosion of platform social data as digital secondary data, collectible through sophisticated and automatized query systems or algorithms, makes it possible to accumulate huge amounts of dense and miscellaneous data. The challenge for social researchers becomes how to extract meaning and not only trends in a quantitative as well as in a qualitative manner. Through the application of a digital mixed content analysis perspective to data analysis, in this contribution, the author will present the potentiality of a hybrid digitalized approach to social content. This perspective should be seen as an applied example of organizing a framework to guide the application of integrated methods of content analysis (quantitative and qualitative) but also integrated objects of analysis (individuals, relationships, and digital actions) on digital platform social data and to address their varied nature.

Authors: Lin Chiu-Pin , Yang Su-Jian
Published: August 2021

This study uses the knowledge structure of the adaptive learning platform to explore the model of elementary school students' self-regulated learning of mathematics. The research objects are 85 students who are in grade five. In the two experimental groups, students are divided into groups to carry out scaffold-support self-regulated learning and experimental teaching. The control group conducts traditional teaching. The results of the study show that: 1) The self-regulated learning model supported by multiple scaffolding performs better than the traditional teaching models in learning mathematics. And it is also superior to the traditional narrative of only teaching materials provided by the digital learning platform. 2) The learning performance of high achievement students is higher in Experimental Group 1 compared to all the other groups. 3) Students in Experimental Group 1 have more confidence in themselves as compared to those of Experimental Group 2 with regards to these five aspects including self-regulated learning/planning, self-monitoring, evaluation, reflection, and effort.
Interstitial Lung Disease and Diffuse Alveolar Hemorrhage, the Two Key Pulmonary Manifestations in Microscopic Polyangiitis
Authors: Kim Min Jung , Shin Kichul
Published: August 2021

Microscopic polyangiitis (MPA) is an antineutrophil cytoplasmic antibody (ANCA)‒associated necrotizing vasculitis, which mainly affects small vessels in various organs, especially the lungs. The two key pulmonary manifestations, interstitial lung disease (ILD) and diffuse alveolar hemorrhage (DAH), increase the morbidity and death rate of patients with MPA. ILD is more common in MPA than in other ANCA-associated vasculitis subsets and is primarily associated with myeloperoxidase-ANCA. Unlike alveolar hemorrhage due to pulmonary capillaritis, ILD can initially manifest as isolated pulmonary fibrosis. Of note, its most frequent radiographic pattern is the usual interstitial pneumonia pattern, similar to the characteristic pattern seen in idiopathic pulmonary fibrosis. In this review we present the pathogenesis, clinical manifestations, and radiographic and histopathologic features of ILD and DAH in MPA. We also briefly summarize the outcome and therapeutic options for the two conditions.

A COMPARATIVE ANALYSIS OF CONSTRAINT-HANDLING MECHANISMS FOR SOLVING ENGINEERING DESIGN PROBLEMS
Authors: GÖLCÜK İlker
Published: August 2021

Optimization problems have numerous real-life applications in science and engineering. The engineering design problems are usually subject to various constraints. Although many state-of-the-art metaheuristic optimization algorithms have been developed during the last decades, these algorithms require additional constraint-handling mechanisms to cope with constrained optimization problems. Therefore, selecting a suitable constraint-handling mechanism requires extensive trial-and-error experiments, which is time-consuming and demanding. In this study, a comparative analysis of the eight constraint handling mechanisms is carried out, guiding decision-makers in their optimization practices. The constraint-handling techniques are used along with the whale optimization algorithm, and 19 real-life mechanical design problems, which are also part of the CEC2020 benchmark suite, are tested in the experimental analysis. The nonparametric statistical analysis incorporating Nemenyi and Holm post-hoc procedures shows that the inverse tangent constraint-handling and eclectic penalty methods exhibit high performance in real-life mechanical design problems.
MECHANICAL EVALUATION OF 3D PRINTED POLYCAPROLACTONE SCAFFOLDS: EFFECT OF MOLECULAR WEIGHT
Authors: VURAT Murat , PARMAKSIZ Mahmut
Published: August 2021

Three-dimensional (3D) scaffold fabrication with appropriate architectural and mechanical properties is one of the critical components of tissue engineering. There are many traditional/conventional scaffold fabrication techniques such as electrospinning, gas foaming, freeze-drying etc. More recently, there has been increasing interest in the use of 3D printing technologies in scaffold fabrication for tissue engineering application. With the use of 3D printing technology, scaffolds with desired porosity and target damage/tissue architecture can be developed. Various 3D printing based scaffold production studies by using different types of synthetic or natural polymers are available in the literature. In the selection of polymers to be used for printing, parameters such as target scaffold mechanical properties, porosity and solubility should be considered. For example, it is well known that the molecular weights of the polymers can significantly affect the final scaffold mechanical properties. In this study, the effects of molecular weight and nozzle moving speed on the mechanical and physical properties of 3D printed scaffolds were evaluated. For this purpose, biocompatible PCL polymer with different molecular weights was used and ten-layered scaffolds were fabricated at different nozzle speeds. Then, mechanical, morphological and physical properties of the printed scaffolds were analyzed.
Gender, Populism and Anti-Immigrations
Authors: Roth Julia
Published: August 2021

In current struggles over cultural hegemony, conservative and right-wing populist dis- course is marked by an omni-presence of topics related to gender and sexuality. This article examines the ways in which diverse actors of what will be called the ‘right-wing populist complex’ use gender in order to catapult a variety of arguments into the public sphere with particular focus on actors in the Americas and Germany. Suggest- ing a first set of Right-Wing Populist Patterns of Gendering1, the article pursues the question how seemingly emancipatory arguments function in right-wing discourse, especially in performing a modernisation paradigm, while simultaneously, and in of- ten paradoxical ways, promoting a program of re-traditionalisation. Therefore, often, gender arguments—like the sexual freedom of ‘autochtonous’ women—are used to justify anti-immigration and racist politics. One’s own society can thus be depicted as supposedly already fully emancipated in contrast to the alleged ‘backward’ social order of immigrants. Through this ethno-sexist twist, the article argues that gender provides right-wing populist discourse a useful tool for affectively bridging seemingly paradoxical arguments and transferring diverse social hierarchies shaped by late neo- liberalism onto the gender hierarchy of a society. Since gender as a discursive element is foundational for right-wing discourse, an analytical, systematic and intersectional gender lens—or a critical gender theory—is crucial in right-wing populism research in order to grasp patterns of gendering and their entanglements with racialisation and racist structures.
Model for Clinical Education in Athletic Training
Authors: Seegmiller Jeff
Published: August 2021

Clinical education is an intrinsic part of most allied health educational programs. However, conceptual models differ as to what constitutes quality for clinical experiences. As a relatively new allied health care field, athletic training education is adapting in order to meet the needs of a changing health care environment. Recent initiatives for clinical education mark the change from a quantitative (hours of exposure) approach, to one emphasizing quality (mastery over time). However, in this transition from field-based to curriculum emphasis, the coherence between different aspects of the educational process have weakened. This paper presents a background of clinical education in athletic training and presents a model for allied health education that offers distinct didactic, clinical, and field experience components.
e-Health: A New Approach in Healthcare Practice
Authors: Podichetty Vinod , Biscup Robert
Published: August 2021

The Internet offers an unprecedented opportunity for healthcare information to be disseminated instantaneously. Quality of information, both scientific and nonscientific, and the development of tools to disseminate information securely via the Internet are the two most important issues related to achieving effective and wider exchange of health information. For the first time ever, information can be exchanged simultaneously and interactively all around the world, with the potential of being equally available to healthcare professionals as well as to patients. The big difference between yesterday's knowledge-based patient care and that of tomorrow, is a fundamental premise that patients will explore the web world with a desire to learn more about their condition, including its treatment and prognosis. This has evolved into the concept of e-health (Electronic Health). Evaluation and examination of the information being conveyed via the Internet is important and necessary in order for the Internet to be an effective tool in healthcare.

Published: August 2021

Let R be a commutative ring with identity. The nilpotent graph of R, denoted by ΓN(R), is a graph with vertex set ZN(R)∗, and two vertices x and y are adjacent if and only if xy is nilpotent, where ZN(R) = {x ∈ R∣xy is nilpotent, for some y ∈ R∗}. A perfect graph is a graph in which the chromatic number of every induced subgraph equals the size of the largest clique of that subgraph. In this paper, we characterize all rings whose ΓN(R) is perfect. In addition, it is shown that for a ring R, if R is Artinian, then ω(ΓN(R)) = χ(ΓN(R)) = |Nil(R)∗| + |Max(R)|.

Published: August 2021

In this paper, a special type of fourth-order diﬀerential equations with a perturbed nonlinear term and some boundary conditions is considered which is very important in mechanical engineering. Therefore, the existence of a non-trivial solution for such equations is very important. Our goal is to ensure at least three weak solutions for a class of perturbed fourth-order problems by applying certain conditions to the functions that are available in the diﬀerential equation (problem (??)). Our approach is based on variational methods and critical point theory. In fact, using a fundamental theorem that is attributed to Bonanno, we get some important results. Finally, for some results, an example is presented.

Econometric Assessment of the Impact of Exchange Rate Depreciation on Inflation in Nigeria (1981-2017)
Authors: Abubakar MA , Apeh K , Nweze ON
Published: August 2021

The present reality of the Nigerian economy is the fact that inflation has remained unabated in spite of all exchange rate measures that have been adopted by the monetary authority. This calls for investigation into the extent to which exchange rate impact on inflation in Nigeria. The research paper examined the impact of exchange rate depreciation on inflation in Nigeria for the period 1981–2017, using Auto Regressive Distributed Lag (ARDL) Bounds Test Cointegration Procedure. The research shows that inflation rate in Nigeria is highly susceptible to lagged inflation rate, exchange rate, lagged exchange rate, lagged broad money, and lagged gross domestic product at 5% level of significance. A long run relationship was also found to exist between inflation rate, gross domestic product and general government expenditure, indicating that the model has a self-adjusting mechanism for correcting any deviation of the variables from equilibrium. Therefore, this study concludes that exchange rate is an important tool to manage inflation in the country; thus, this paper recommends that policies that have direct influence on inflation as well as exchange rate policies that would checkmate inflation movement in the country, should be used by the Central Bank of Nigeria. Also, monetary growth and import management policies should be put in place to encourage domestic production of export commodities, which are currently short-supplied. In addition, policy makers should not rely on this instrument totally to control inflation, but should use it as a complement to other macro-economic policies.

Published: August 2021

Proximate and phytochemical analyses of the root extracts of Justicia carnea and Justicia  secunda in the Acanthaceae family were investigated using standard procedures and compared. The result of the proximate analysis indicated that the roots of both species contain nutrients in varying levels. Protein (11.38±0.01), lipid (4.81±0.01) and moisture content (17.01±0.01) were higher in the roots of J. carnea than in J. secunda (8.32±0.01, 2.01±0.01, 11.22±0.02) respectively, while Carbohydrate (6.62±0.00), Ash (16.75±0.05) and Fibre (55.18±0.01) were higher in J. secunda than in J. carnea  (4.73±0.02, 9.81±0.01, and 52.29±0.00) respectively. Qualitative phytochemical analysis showed the presence of tannin, flavonoid, alkaloids, saponin, phytate and cyanogenic glycosides whereas the result for the quantitative analysis showed that the quantity of phytochemicals in Justicia carnea and Justicia secunda were: tannin (46.75±0.00 and 41.01±0.01), flavonoid (2.72±0.01 and 3.21±0.00), alkaloid (10.16±0.00 and 11.21±0.01), saponin (3.31±0.01 and 2.7±0.00), phytate (30.54±0.01 and 33.86±0.00) and cyanogenic glycoside (100.01±0.00 and 500±0.00) respectively. Justicia carnea contained higher quantity of tannin and saponin while Justicia secunda contained higher amount of flavonoid, alkanoid, phytate and cyanogenic glycoside. These results conceivably indicated that the two species are good sources of essential nutrients which could be used in diets to supplement the daily nutrient needs in humans and animals, and phyto-nutrients which possess strong pharmacological activities, providing scientific credence for its therapeutic usage in folklore medicine.

Published: August 2021

The ability to analyse the rate of fire spread outbreak in a real-time coupled Atmospheric-vegetation fire has become increasingly vital as forest fire fighters are building diverse kinds of models to combat the dangers/effects of fire spread across a given fire vicinity. This paper theoretically examines the analysis of fire spread in a real fire environment. A partial differential equations (PDE) governing the phenomenon is presented. The analytical solution of the model is obtained via direct integration and eigenfunction expansion technique, which displays the influence of the parameters involved in the system. The effect of change in parameters such as Frank-Kamenetskii number, Radiation number, Peclet energy number and Activation energy number are presented graphically and discussed. The results obtained show that Frank-Kamenetskii number, Radiation number, Peclet energy number, and Activation energy number all reduced transient state temperature.

Published: August 2021

Cyperus rotundus, a member of family Cyperaceae is a perennial, stoloniferous herb. The study investigated the secondary metabolites present in the leaf of Cyperus rotundus and antimicrobial activities of the hexane, ethyl acetate and methanol extracts. Phytochemical analysis revealed the presence of saponins, alkaloids, phenolic compounds, tannins, steroids, flavonoids, cardiac glycosides and terpenoids. The qualitative test of the extracts show the presence of steroid only in the hexane extract; flavonoid, cardiac glycoside in both the ethyl acetate and methanol extracts; saponin and tannin and phenolics in just the methanol extract. While alkaloid was present in all the extracts, terpenoid was absent in all. Antimicrobial activity of plant extracts were monitored using the agar disk-diffusion method against strains gram-positive bacterial: Staphylococcus aureus, Pseudomonas aeruginosa; and gram-negative bacteria: Escherichia coli, Salmonela typhi, and strains of fungi: Candida albicans and Aspergillus niger. The antimicrobial activity of the extracts was monitored at different concentrations of 50, 25, 12.5 and 6.25 mg/mL prepared from the stock concentration (100mg/mL) by serial dilution; with standard drugs: ciprofloxacin and fluconazole. The inhibition of the test organisms were concentration dependent. The methanol extract showed significantly higher Inhibition Zone (IZ) and Activity Index (AI) against the microbes at all concentrations compared to the ethyl acetate and hexane extracts due to the much phytochemicals (saponins, tanins, phenols, flavonoids, cardiac glycocides and alkaloids) found present in its extract. The overall study results signify the potential of Cyperus rotundus as a source of therapeutic agents. The methanol extract showed the best activity against both bacterial and fungal pathogens at the highest concentration of 100 mg/mL, especially the most susceptible bacteria: Staphylococcus aureus (IZ of 25.0±1.5; AI of 0.96) and Candida albicans (IZ of 25.5±0.5; AI of 0.91). At MIC, MBC and MFC of 6.25 mg/mL and 12.5 mg/mL, the plant extracts showed effective bactericidal and fungicidal effect against the test microbes.

Published: August 2021

Pollen of Litchi chinensis (Litchi) is a major aeroallergen of Bangladesh. Pollen of this fruits plant was collected from full bloomed flower growing in different places of Rajshahi in Bangladesh. Pollen protein was extracted and partial purified by means of long-term PBS extraction, salting out, dialysis, gel filtrations and DEAE-Cellulose chromatography and the protein was designated as LFPP (Litchi flowers pollen protein). Gel filtration of the purified pollen protein gives two main peaks. The major peak gives four bands on SDS-PAGE. The enzyme (pectate lyase) proteins after gel filtration again re-purified by Ion exchange chromatography, a single band in the protein profile of LFPP, (M.W. 28kDa) was the major allergenic component of Litchi chinensis (Litchi) flower pollen. The homogeneity and the molecular weight of the protein were estimated by SDS-PAGE, and Gel filtration was 28kDa. The allergenic protein was identified by skin prick tests and showed the pectate lyase (Pel) activity. Skin-prick tests also revealed highest degree of sensitivity to the Nawabgang sample giving positive response in 80% of the patients. Skin reactivity ranged between 1+ and 3+.

In order to examine the effect of phytase supplementation in the diet of laying hen this experiment was conducted with 30 commercial hybrid Babcock-380 layers of 73 weeks of age. The hens were grouped into 3 treatment groups and given microbial phytase (Rena Phytase 400) at levels 2.5, 1.5 and 0 (control) g/kg feed in addition to their basal diet (110 g commercial pellet/day). Records on egg production/group/day, egg mass weight/day, body weight of hens at the end of experimental period were taken and analysed. Results revealed that hen house egg production (HHEP) and egg weight (EW) varied (p<0.05) among the treatment groups but level of phytase did not affect (p<0.05) body weight of hens. Both HHEP and EW were in order of 2.5>1.5>0 g/kg feed phytase group and all the means were significantly (p<0.05) different from each other within treatment groups. Microbial phytase supplementation in layer ration proved to be beneficial in terms of egg production and egg size even after 72 weeks of age of hens. Layer farms in Malaysia can use this technology to earn more profit.

Using natural wood-fiber as reinforcement in commercial thermoplastics is gaining momentum due to its high specific properties and renewable resources. In this study, the effect of wood particle geometry size on mechanical properties of thermoplastics composite was investigated. The wood species that has been chosen is Kelempayan species (Neolamarckia cadamba) and reinforced with polypropylene using fiber geometry size of 75 and 250 ?m. Thermoplastic composites were produced from two types of ratio (30:70 and 10:90) between wood-fiber and polypropylene. Static bending and tensile strength were tested. The result showed that wood-fiber from 75 ?m geometry sizes with ratio of 30:70 between wood-fiber and polypropylene was most suitable in producing thermoplastic composites. The geometry sizes of wood particle as well as the ratio between wood-fiber and polypropylene were found to influence the mechanical properties of the thermoplastic composites.

Authors: Afandi Asrul , Sarijan Shazani , Kumar Shaha Ranajit
Published: August 2021

A solid-liquid extraction and an HPLC method for determination of rebaudioside A from the leave parts of Stevia rebaudiana were developed. Separation method consisted of solvent extraction of leaf powder using various solvents like petroleum ether, methanol, diethyl ether and butanol followed by its purification using high performance liquid chromatography in order to obtain bioactive compound rebaudioside A. This solvent selection is very important prior to alternative extraction methods since it can be used as a pre-extraction solvents, main solvents, or co-solvents. The problem of hydrolysable components and solvent removal difficulties in the conventional extraction led us to study further the effects of solvent properties on the conventional extraction using Soxhlet method in order to determine the best solvent or solvent mixture for high extraction yield of S. rebaudiana. The chromatographic separation was realized using a C18 column, mobile phase consisting of methanol: water with UV detection at 210 nm. Based on the yield of extraction and glycosides content, methanol was found to be best solvent.

The study was carried out to investigate the phenotypic and genetic potential of reproductive traits of Red Chittagong Cattle (RCC) of Bangladesh. For that purpose accumulated data on a total of 101 animals from four different herds covering a period from 2005 to 2011 were used for analyses. The overall mean (±SE) values of age at first heat (AFH), age at first conception (AFC), age at first calving (AC), calving rate per productive year (CR), interval to post partum heat (IPPH), days open (DO), calving interval (CI) and generation interval (GI) were 35.9±1.1 month, 42.1±1.3 month, 50.6±1.1 month, 0.87±0.01 month, 149.4±9.5 days, 178.6±11.0 days, 454.9±10.4 days and 4.2±0.1 year, respectively. The factors having significant effects on reproductive traits were herd on DO and CI and calving year on DO. Calving parity and calving season had no significant effect on those traits. The heritability estimates of IPPH, DO and CI were very low (0, 0.06 and 0.09) and that of corresponding repeatability estimates were also low (0.06, 0.08 and 0.09, respectively). The heritability estimates for other traits were moderate (0.39 to 0.50). The results indicated that though reproductive potential of RCC for most of the traits are below than expected, that may be due to their lower inherent capability of indigenous Zebu compared to Taurus, but there is still opportunity of considerable improvement of these traits studied as indicated by their phenotypic variations among population.

Published: August 2021

The trends of illegal logging and current situation of illegal logging in Peninsular Malaysia were studies. Data and information from year 2001 to 2010 on volume of log productions (m3) and volume of illegal log productions were collected from the government and private sectors such as the Forestry Department Peninsular Malaysia (FDPM), International Tropical Timber Organization (ITTO) and Food and Agriculture Organization (FAO). The data obtained were statistically analyzed using the correlation analysis to determine the direction and the strength of the relationship between log productions and illegal log productions. The results showed that the trends of illegal logging are on the increased. Eighteen percents (18%) of the logs cut annually are obtained from illegal operation. The log productions and illegal log productions resulted have a weak negative relationship as r = -0.271, p = 0.603 and do not significantly related. The illegal log productions are inversely related with the log productions. It can be concluded that the log productions in Peninsular Malaysia occurred in a small scale and the situation is under control. Proper long-term planning needs to be generated and implemented to prevent the problem from becoming worse.

Authors: Yusoff Mahani , H Zuhailawati
Published: August 2021

In this study, nanostructured copper tungsten carbide composite was produced by mechanical alloying. Mechanical alloying was carried out by milling of copper (Cu), tungsten (W) and graphite mixture at 40 h with milling speed of 400 rpm in planetary ball mill using two different ball sizes. The crystallite size of the powder milled with 10 mm ball is smaller than 20 mm ball due to higher collision frequency. Lower expansion of Cu lattice was found for the powder milled with 20 mm ball than that of 10 mm ball. The composite obtain by milling with 20 mm ball had produced greater impact energy that facilitated the formation of tungsten carbide (WC).
Role of BERNAS as Government Linked Company (GLC) – Supporting and Complementing National (Malaysia) Food Security Food Policies
Authors: Muhammad Salman
Published: August 2021

As the privatized foodgrain management agency, BERNAS plays its roles in supporting and complementing the national food security policy of Malaysia. These include: (1) promoting market stability and thereby stabilizing rice prices, making them affordable to the consumers; (2) ensuring sufficient supply of rice of various grades and qualities anywhere in the country, making rice easily accessible to all; and (3) supporting the sustainability of domestic rice production which is deemed important to the national food security. These roles have established BERNAS as a ?rice institution? rather than a ?rice shop? whereby its main function is not to compete with other players in the market, but to make sure that all players in the industry would have sufficient margin to enable them to continue with their respective businesses. In doing so, BERNAS serves the interests of all stakeholders in the paddy and rice industry, including farmers, industry players, consumers, government and the nation as a whole. Due to these roles, BERNAS always has to balance between its commercial interest, since it must make reasonable profit in order to survive, and the interest of the nation as a whole. It is a delicate task in ensuring the confidence of the public and various stakeholders.

This paper presents the assessment of wound healing properties of ethanolic extract of Acrostichum aureum and A. speciosum in rats. It was carried out on 6 treated groups with 6 rats each group. The excisional wound was made on the dorsal interscapular region of each rat by a 6 mm biopsy punch. T1 and T2 were treated with 5% and 10% A. aureum ethanolic extract in aqua cream, respectively. Meanwhile, T3 and T4 were treated with 5% and 10% A. speciosum ethanolic extract in aqua cream, respectively. Solcoseryl jelly and aqua cream were used as positive and negative controls. The treatments were applied topically twice daily, wound contraction and period of epithelization were measured every 2 days. The results showed that wound treated with 10% A. speciosum (T4) exerted faster wound contraction significantly (p < 0.05) compared to the negative control. It was also enhanced epithelization period (9.33 ± 3.20 days) of the wounds significantly (p < 0.05). In conclusion, these results strongly suggested the beneficial effects of both plant extracts for enhancing wound healing process.
