The objective of the present work was to analyze the cytotoxic, antimicrobial activity and the action mechanism of the major component in of the Syzygium aromaticum essential oil obtained by supercritical CO2. In this work, gingival fibroblasts were exposed to the essential oil in different concentrations for one hour: 5 μL/ml, 7.5 μL/ml and 10 μL/ml. Culture medium was used as control. Cytotoxicity analysis was performed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT®) method. The susceptibility was evaluated on three microorganisms Candida albicans, Escherichia coli and Staphylococcus aureus. The statistical analyses showed significant difference in cell viability for the concentration of 10 μL/mL, as compared to the control group. As a result, the plant extract had no cytotoxicity at concentrations below 10 μL/mL in human gingival fibroblasts. The interaction mode of eugenol, the major compound and main component responsible for the biological activity of the essential oil was evaluated. The molecular docking of eugenol with important proteins of the metabolic pathway of the microorganisms C. albicans, E. coli and S. aureus were performed. The results demonstrated that the compound is capable of interacting with catalytic residues of the enzymes and forming an energetically favorable system with such proteins. The results of binding free energy obtained demonstrate this capacity. For the eugenolN-myristoyltransferase (C. albicans) system, the value of ΔGbind was –19.01 kcal/mol, for Enoyl reductase (E. Coli) ΔGbind was equal to –11.31 kcal/mol and for SarA (S. aureus) ΔGbind was –13.58 kcal/mol.

Abstract Background To test the antimicrobial potential of clove essential oil that has been less investigated on antimicrobial-resistant organisms (extended-spectrum β-lactamase-ESBL-producing Escherichia coli), we collected 135 ESBL-producing Escherichia coli strains given that E. coli is the major organism increasingly isolated as a cause of complicated urinary and gastrointestinal tract infections, which remains an important cause of therapy failure with antibiotics for the medical sector. Then, in this study, we evaluated the relationship between the antibacterial potential activity of Syzygium aromaticum essential oil (EOSA) and the expression of antibiotic-resistant genes (SHV-2, TEM-20) in plasmidic DNA on ESBL-producing E. coli using RT-PCR technique. Results EOSA was obtained by hydrodistillation. Using Kirby-Baüer method, we found that EOSA presented a smaller media (mean = 15.59 mm) in comparison with chloramphenicol (mean = 17.73 mm). Thus, there were significant differences (p < 0.0001). Furthermore, EOSA had an antibacterial activity, particularly on ECB132 (MIC: 10.0 mg/mL and MBC: 80.0 mg/mL), and a bacteriostatic effect by bactericidal kinetic. We found that the expression of antibiotic-resistant gene blaTEM-20 was 23.52% (4/17 strains) and no expression of blaSHV-2. EOSA presented such as majority compounds (eugenol, caryophyllene) using the GC–MS technique. Conclusions Plant essential oils and their active ingredients have potentially high bioactivity against a different target (membranes, cytoplasm, genetic material). In this research, EOSA might become an important adjuvant against urinary and gastrointestinal diseases caused by ESBL-producing E. coli.

Multiple organ dysfunction syndrome (MODS) is a key factor that leads to death in elderly patients with sepsis. Therefore, early prevention and treatment of gastrointestinal dysfunction (GIDF) in elderly patients with sepsis is an important measure to prevent MODS occurrence. This research explores the correlation between intestinal microflora and GIDF in elderly patients with sepsis and provides ideas for the prevention and treatment of GIDF in elderly patients with sepsis. In this study, 152 patients with sepsis (122 patients with sepsis and GIDF) treated in the Third Affiliated Hospital of Yunnan University of Chinese Medicine from January to September 2019 were selected as the sepsis group and 100 elderly who had normal physical examination results were selected as the control group. The common intestinal microflora of the two groups was compared. Patients with sepsis and GIDF were treated as the GIDF group and the other patients with sepsis were treated as the non-GIDF group. The common intestinal microflora, gastrointestinal indicators, serum inflammatory factors, and immune function indices were compared between the two groups. Correlation analysis of the observed indices with statistical significance was carried out. The results showed 152 patients with sepsis and 122 patients with sepsis and GIDF; thus, the incidence of sepsis with GIDF was 80.26%. The total average score of sepsis with GIDF was 3.61±0.09. There was no statistically significant difference in GIDF scores of patients ages 65–75 and > 75 years old. The number of Bifidobacterium and Lactobacillus in elderly patients with sepsis was lower and the number of Escherichia coli was higher than in the control group. In elderly patients with sepsis, the number of Bifidobacterium and Lactobacillus in the GIDF group was lower and the number of E. coli was higher than in the non-GIDF group. White blood cell (WBC) count, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), gastrin (GAS), and diamine oxidase (DAO) in GIDF patients were higher and motilin (MOT), CIT (CIT), CD4+, and CD8+ were lower than in the non-GIDF group. WBC count, PCT, CRP, TNF-α, GAS, and DAO were negatively correlated with the number of Bifidobacterium and Lactobacillus but positively correlated with E. coli. MOT, CIT, CD4+, and CD8+ were positively correlated with the number of Bifidobacterium and Lactobacillus but negatively correlated with E. coli. There was a negative correlation between Bifidobacterium and Lactobacillus and GIDF score and a positive correlation between E. coli and GIDF score. Therefore, the change in the intestinal microflora in elderly patients with sepsis is related to GIDF.

Material Scarcity

The bark of Cinnamomum burmannii Blume is the main raw material of Cinnamomum oil because its cinnamaldehyde content is higher than in the other parts. This condition lead to the exploitation of Cinnamomum burmannii Blume bark without any cultivation effort, thus it can cause the raw material scarcity. Twigs and leaves of Cinnamomum burmannii Blume are also known to contain cinnamaldehyde therefore it provide a potential alternative source of cinnamaldehyde. The purpose of this research is to investigate the characteristic of Cinnamomum burmannii Blume essential oil which includes refractive index, profiling of chemical constituent and percentage of cinnamaldehyde as a marker compound. This research used three fresh Cinnamomum burmannii Blume simplicia of bark, twigs and leaves from two selected growing locations: Tawangmangu and Purwokerto. Simple water distillation method was conducted, together with characterization and refractive index using refractometer, followed by qualitative and quantitative analysis with Thin Layer Chromatography (TLC) and Gas Chromatography (GC). The results showed Cinnamomum burmannii Blume oil derived from bark, twig and leaf have different profiles, but all have cinnamaldehyde as the main component. The leaf produces higher essential oil yield percentage compared to the twig with a cinnamaldehyde content that is comparable to the bark by 50% of cinnamaldehyde content in cinnamomum bark oil.

Abstract Background: The tick Haemaphysalis longicornis is well known as vector of several zoonotic pathogens responsible for various clinical conditions, increasingly threatens the veterinary and public health. It is mainly distributed in East Asia, New Zealand, Australia, and several Pacific islands, and has been expanded rapidly in United States since its first founding on a nonimported domestic sheep in New Jersey. Glutathione S-transferases (GSTs) are phase II detoxification enzymes, which function via combining with pesticidal molecules and catalyzing the conjugation of molecules by thiol of glutathione, so as to protect tissues from oxidative stress damage. In the tick H. longicornis, glutathione S-transferases (HlGST and HlGST2) have been previously identified. However, the relationship between the expression of glutathione S-transferases and the essential oil treatment in ticks remains unexplored. Hence, in the present study, the expression profiles of HlGST and HlGST2 mRNAs were evaluated in H. longicornis after exposure to Cymbopogon citratus essential oil. Results: At 24 h post-exposure of H. longicornis to different sublethal concentrations of C. citratus essential oil, ANOVA results revealed significant difference (F2,6 = 55.94, P = 0.0001) in the expression of HlGST. Tukey’s test showed that HlGST was significantly induced after treatment with 1% C. citratus essential oil (P = 0.0002); whereas no significant difference (P = 0.3551) was detected after treated by 2% C. citratus essential oil. No significant difference (F2,6 = 0.8990, P = 0.4555) in the expression of HlGST2 between the treatment and the control group of 50% ethanol. Nevertheless, the under-expression of HlGST2 in the treatment groups versus the untreated control group was not significant (F3,8 = 2.643, P = 0.1208). Conclusion: The results implied that GST mRNA is a potential molecular target for C. citratus essential oil in H. longicornis. Further understanding of the underlying mechanisms of the GST at the molecular level could contribute to develop effective control measures for ticks and tick-borne diseases.

The study to improve the quality of Indonesia betel leaves oil is done by treatment of citric acid and sodium carbonate. The treatment showed that the iron content and acid value were reduced optimally in the addition of 5% (w/w) citric acid (12 hours, 50oC) and 5% (w/w) sodium carbonate (9 hours, 50oC) yielded 0.45 mg/L of iron content and 1.00 mg/g of acid value, respectively. The main component of Indonesia betel leaves oil are 4-allyl phenylacetate. The descriptive sensory analysis showed that there were differences between betel leaves oil from Bogor compared with Boyolali and Makassar. There is a significant difference that the content of betel leaves oil from Bogor contains an isoeugenol compound of 20.71% while, Boyolali and Makassar contain eugenol of 17.02 and 19.21%, respectively. The study of the insect repellency indicated that Indonesia betel leaves oil potentially used as mosquito of Aedes aegypti repellent.

Glutathione S-transferases (GSTs) are phase II detoxification enzymes, which function via combining with pesticidal molecules and catalyzing the conjugation of molecules by thiol of glutathione, so as to protect tissues from oxidative stress damage. In the tick Haemaphysalis longicornis, glutathione S-transferases (HlGST and HlGST2) have been previously identified. However, the relationship between the transcription of glutathione S-transferases and the essential oil treatment in ticks remains unexplored. Hence, in the present study, the transcription profiles of HlGST and HlGST2 mRNAs were evaluated in H. longicornis after exposure to Cymbopogon citratus essential oil. At 24 h post-exposure of H. longicornis to different sublethal concentrations of C. citratus essential oil, there was significant difference (P = 0.0001) in the transcription of HlGST. Tukey’s test showed that HlGST was significantly induced after treatment with 1% C. citratus essential oil (P = 0.0002); whereas no significant difference (P = 0.3551) was detected after treated by 2% C. citratus essential oil. No significant difference (P = 0.4555) in the transcription of HlGST2 between the treatment and the control group of 50% ethanol. Nevertheless, the down-regulation of HlGST2 in the treatment groups versus the untreated control group was not significant (P = 0.1208). The above results imply that the essential oil can modulate the expression of GST mRNA, therefore, further understanding of the underlying mechanisms of the GST at the molecular level could contribute to the development of effective control measures for ticks and tick-borne diseases.

AbstractBackgroundAnxiety is the most common psychological reaction in women during labor. Similar to numerous other surgeries, postoperative pain is also reported following cesarean section (C-section). According to the (Gate) Control Theory, there is a relationship between pain and psychological problems such as anxiety. Accordingly, the present study aimed to compare the effect of aromatherapy using lavender and Damask rose essential oils on the level of anxiety and severity of pain following C-section.MethodsThis triple-group randomized clinical trial was performed on 90 mothers who visited Motahari Hospital of Jahrom, Iran, for C-section in 2017. The incidence and severity of pain and anxiety were measured and recorded for all three groups prior to intervention. The intervention groups underwent aromatherapy with lavender and Damask rose essential oils. Patients were asked to inhale cotton balls, separately stained with three drops of each essential oil at a distance of 10 cm for 30 mins. The severity of pain and anxiety was measured using the visual analogue scale (VAS) and the Spielberger State-Trait Anxiety Inventory (STAI) 5 min after the specified process, respectively. The control group underwent aromatherapy in a similar fashion with normal saline. Finally, data were analyzed using descriptive statistical indices and ANOVA and Kruskal–Wallis tests in SPSS 21.ResultsThere was no significant difference between the three groups in the mean severity of pain and anxiety before the intervention (p>0.05). The mean severity of pain and overt anxiety in the lavender and Damask rose aromatherapy groups was significantly different than the control group after the intervention (p<0.001). In addition, no significant difference was observed between the overt and overall anxiety levels of the two intervention groups after the intervention (p>0.05).ConclusionsThe findings suggested that inhalation aromatherapy can reduce the severity of overt anxiety and pain after C-section, with Damask rose essential oil showing a larger effect than lavender.
