OBJECTIVE: To investigate the pharmacodynamic material basis, mechanism of actions and targeted diseases of Salicornia europaea L. (SE) based on the network pharmacology method, and to verify the antidepressant-like effect of the SE extract by pharmacological experiments. METHODS: Retrieval tools including Chinese medicine (CM), PubMed, PharmMapper, MAS 3.0 and Cytoscape were used to search the components of SE, predict its targets and related therapeutic diseases, and construct the "Component-Target-Pathway" network of SE for central nervous system (CNS) diseases. Further, protein-protein interaction (PPI) network, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) function annotation of depression-related targets were analyzed to predict the antidepressant mechanism of SE. Chronic unpredictable mild stress (CUMS) model was used to construct a mouse model with depression-like symptoms. And the animals were randomly divided into 6 groups (n=10) including the normal group (nonstressed mice administered with distilled water), the CUMS group (CUMS mice administered with distilled water), the venlafaxine group (CUMS mice administered with venlafaxine 9.38 mg/kg), SE high-, medium-, and low-dose groups (CUMS mice administered with SE 1.8, 1.35 and 0.9 g/kg, respectively). Then some relevant indicators were determined for experimental verification by the forced swim test (FST), the tail suspension test (TST) and open-field test (OFT). Dopamine (DA) concentration in hippocampus and cerebral cortex, IL-2 and corticosterone (CORT) levels in blood, and nuclear factor E2 related factor 2 (Nrf2), kelch-like epichlorohydrin related protein 1 (Keap1), NAD(P) H dehydrogenase [quinone] 1 (NQO1) and heme oxygenase-1 (HO-1) levels in mice were measured by enzyme linked immunosorbent assay (ELISA) and Western blot respectively to explore the possible mechanisms. RESULTS: The "target-disease" network diagram predicted by network pharmacology, showed that the potential target of SE involves a variety of CNS diseases, among which depression accounts for the majority. The experimental results showed that SE (1.8, 1.35 g/kg) significantly decreased the immobility period, compared with the CUMS group in FST and TST in mice after 3-week treatment, while SE exhibited no significant effect on exploratory behavior in OFT in mice. Compared with CUMS group, the SE group (0.9 g/kg) showed significant differences (P<0.05) in DA levels in the hippocampus and cerebral cortex. In addition, compared with CUMS control group, SE (1.8 g/kg) group showed a significant effect on decreasing the activities of CORT (P<0.05), and serum IL-2 level with no statistical significance. Finally, Western blot results showed that compared with the model group, Nrf2, Keap1, NQO1 and HO-1 protein expressions in SE group (1.8 g/kg) were up-regulated (all P<0.01). CONCLUSION The SE extract may have an antidepressant effect, which appeared to regulate Nrf2-ARE pathway and increased levels of DA and CORT in the hippocampus and cortex.

Objective: To analyze the clinical characteristics of Chenopodiaceae pollen induced seasonal allergic rhinitis (SAR) as well as the distribution and sensitization characteristics of Chenopodiaceae pollen in Inner Mongolia grassland of northern China. Methods: From May 2015 to August 2015, using stratified, cluster and random sampling, a field interviewer-administered survey study and skin prick test (SPT) were conducted in six areas of Inner Mongolia grassland (Xilinhot, Erenhot, Duolun, Tongliao, Jarud, Kailu), and pollen monitoring was carried out in the above six areas from January 1 to December 31 of 2015. The clinical characteristics of Chenopodiaceae pollen induced SAR, distribution and sensitization characteristics of Chenopodiaceae pollen in these regions were observed. SAS software 9.4 was used for data processing. Results: A total of 6 043 subjects completed the study. The prevalence of Chenopodiaceae pollen induced SAR was 13.2% (795/6 043). The highest prevalence was found in the 18-39 age group. Subjects from urban areas showed higher prevalence of SAR than rural areas (61.2% vs 37.9%, P<0.001). There was significant regional difference in the prevalence rate of Chenopodiaceae pollen induced SAR among the above six areas (Xilinhot 21.5%, Erenhot 17.8%, Duolun 8.9%, Tongliao 6.9%, Jarud 15.3%, Kailu 9.7%, P<0.001). The main clinical symptoms of Chenopodiaceae pollen induced SAR were sneezing (96.5%) and nasal itching (92.2%). Eye itching was more obvious among the ocular symptoms (69.1%), while fatigue (32.1%) and drowsiness (31.5%) were more prominent among other related symptoms. Among comorbidities of Chenopodiaceae pollen induced SAR, allergic conjunctivitis accounted for 71.4% (568/795), food allergy accounted for 86.7% (689/795) and asthma accounted for 16.7% (133/795). The peak of Chenopodiaceae pollen spread was in August. The prevalence of Chenopodiaceae pollen induced SAR was positively correlated with the concentration of Chenopodiaceae pollen (R²=0.78, P=0.043). The SPT positive rate of Chenopodiaceae pollen was 21.2% (1 282/6 043), and Xilinhot had the highest rate in six regions (28.0%, 236/842). Conclusions: The prevalence of Chenopodiaceae pollen induced SAR in Inner Mongolia grassland stays at a high level. Sneezing is the most obvious symptom of SAR. The peak of Chenopodiaceae pollen spread is in August and the prevalence of Chenopodiaceae pollen induced SAR is positively correlated with the pollen concentration.

The primary objective of this study was to develop an optimal composite recipe for ginger extract candy with Salicornia herbacea L., for consumption during the first trimester of pregnancy. The secondary objective was to examine quality characteristics of the candy. The physical and mechanical properties and sensory properties for pregnant women in were measured, and these values were applied to mathematical models. Time of stirring water solution, saltiness, pH, and redness of the candy increased as concentrations of ginger juice did, but variations in pH were not significant. The hardness values of the candy ranged from 3,063.90 to 5,681.65 dyne/cm³. The average values of sweetness and time stirring the water solution were 5.36% and 14.1 minutes, respectively. However, hardness and sweetness stirring water solution were not significant. The range of sensory values of color (P < 0.01), flavor (P < 0.05), sweetness, saltiness, spiciness, and overall quality (P < 0.05) ranged from were 3.73~5.32, 4.05~5.05, 3.67~5.14, 3.59~5.09, 3.55~5.15, and 3.32~5.45, respectively. Results suggest that ginger extract candy with Salicornia herbacea L. should be comprised of 7.37 g of ginger juice and 1.77 g of salt. Consequently, it could be a functional candy for pregnant women.

OBJECTIVEAnabasis aretioides (Coss & Moq.), a Saharan plant belonging to Chenopodiaceae family, is widely distributed in semi-desert areas from the Tafilalet region of Morocco. This plant is extensively used by local population against diabetes and cardiovascular disorders. The purpose of the study was to investigate the effect of the aqueous A. aretioides extract on lipid metabolism in normal and streptozotocin (STZ)-induced diabetic rats and to identify the polyphenolic compounds present. In addition, the in vitro antioxidant activity of the aqueous A. aretioides extract was also evaluated.

METHODSThe effect of an aerial part aqueous extract (APAE) of A. aretioides (5 mg/kg of lyophilized A. aretioides APAE) on plasma lipid profile was investigated in normal and STZ-induced diabetic rats (n = 6) after once daily oral administration for 15 days. The aqueous extract was tested for its 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity. Polyphenolic compounds in the extracts were definitively characterized by high-performance liquid chromatography-diode array detection-electrospray ionization-mass spectrometry.

RESULTSIn diabetic rats, oral administration of A. aretioides APAE provoked a significant decrease in both plasma cholesterol and triglyceride levels from the first to the second week (P < 0.01). A significant decrease on plasma triglyceride levels was also observed in normal rats (P < 0.01), where the reduction was 53%. In addition, the phytochemical analysis revealed the presence of 12 polyphenolic compounds. Moreover, according to the DPPH radical-scavenging activity, the aqueous extract showed an in vitro antioxidant activity.

CONCLUSIONAqueous A. aretioides APAE exhibits lipid-lowering and in vitro antioxidant activities. Many polyphenols were present in this extract and these phytoconstituents may be involved in the pharmacological activity of this plant.

The aim of this study was to measure and compare polyphenol content, antioxidant, and anti-inflammatory activity of six halophytes (Limonium tetragonum, Suaeda glauca, Suaeda japonica, Salicornia europaea, Triglochin maritimum, and Sonchus brachyotus). Depending on the total polyphenol content, the plants were categorized into two groups: (1) a high total polyphenol content group that included L. tetragonum, S. brachyotus, and S. europaea, and, (2) a low total polyphenol content group consisting of S. glauca, T. maritima, and S. japonica. Antioxidant activity was evaluated using DPPH and hydroxyl radical scavenging assays, and by measuring ROS. Anti-inflammatory activity was evaluated by measuring NO and PGE₂. L. tetragonum and S. brachyotus, that have high polyphenol content, also showed strong antioxidant activity. In addition, L. tetragonum, S. brachyotus, and S. europaea showed good anti-inflammatory activity. Consequently, the total polyphenol content was thought to be related to antioxidant and anti-inflammatory activity. Therefore, S. brachyotus and L. tetragonum are good candidates for use in pharmaceuticals and functional foods.

Halophytes are expected to possess abundant secondary metabolites and various biological activities because of habitat in extreme environments. In this study, we collected 14 halophytes (Asparagus oligoclonos, Calystegia soldanella, Carex pumila, Chenopodium glaucum, Elymus mollis, Glehnia littoralis, Limonium tetragonum, Messerschmidia sibirica, Rosa rugosa, Salsola komarovii, Spergularia marina, Suaeda glauca, Suaeda maritima, and Vitex rotundifolia) native to Korea and compared their total polyphenol contents, antioxidant and anti-inflammatory activities. The total polyphenol contents of R. rugosa (27.28%) and L. tetragonum (13.17%) were significantly higher than those of the other 12 halophytes and L. tetragonum, R. rugosa, and M. sibirica showed significantly greater antioxidant activities than the other 11 halophytes, as determined by DPPH (2,2-diphenyl-1-picrylhydrazyl). A. oligoclonos, E. mollis, and C. pumila showed significantly greater anti-inflammatory activities than the other 11, as determined by NO (Nitric oxide) and PGE₂ (Prostaglandin E₂) levels. In contrast, these three extracts had normal and low total polyphenol contents among the 14 halophytes. Consequently, the total polyphenol content in the 14 studied halophytes appeared to be related to antioxidant, but not anti-inflammatory activity levels.

BACKGROUND: Pollen allergens are one of the main contributors to the development and/or aggravation of allergic rhinitis, allergic conjunctivitis, and asthma. OBJECTIVE: An examination of the airborne pollen in residential areas should be conducted to aid the diagnosis and treatment of allergic diseases. METHODS: Airborne pollen samples were collected from 2 sites in Incheon and 2 in Seoul from 2015 to 2016. RESULTS: The highest monthly concentration of airborne pollen was observed in May and September each year. Pollen from 32 families and 50 genera was identified over the 2 years; of these, Pinus spp. showed the highest pollen concentration (41.6%), followed by Quercus spp. (25.3%), and Humulus spp. (15.3%), the latter of which had the highest concentration among weed pollen. The total pollen concentration was significantly higher in Incheon than in Seoul (p = 0.001 in 2015, p < 0.001 in 2016) and higher in 2016 than in 2015. The concentrations of pollen from weed species (Cupressaceae, Humulus spp., Artemisia spp., Ambrosia spp., and Chenopodiaceae) and grass species (Gramineae) were significantly higher (p < 0.001) than those from tree species. Pollen was distributed from February to November. The first pollen identified in both regions in each year was Alnus spp. Overall, the total concentration of Quercus spp., Betula spp., Humulus spp., Artemisia spp., Ambrosia spp., and Chenopodiaceae pollen increased significantly over the 2 years. CONCLUSION: Region-specific differences exist in the pollen of major allergenic plants. Continuous monitoring of pollen is thus essential for management of pollen-related allergic disorders in each region.

PURPOSE: The objective of this study was to examine whether Hamcho freeze-dried powder and Hamcho freeze-dried nano powder have an anti-obese effect on high fat diet-induced obese rats. METHODS: Sprague Dawley rats were divided into 6 different groups, each of which was bred for 8 weeks with a different experimental diet: normal diet group (NC), high fat diet group (HFC), high fat diet + 2% Salicornia herbacea L. freeze-dried powder group (2% HS), high fat diet + 5% Salicornia herbacea L. freeze-dried powder group (5%HS), high fat diet + 1% Salicornia herbacea L. freeze-dried nano powder group (1% HSN), high fat diet + 2% Salicornia herbacea L. freeze-dried nano powder group (2% HSN). RESULTS: The 5% HS group showed a weight loss effect in body weight, liver and adipose tissue by reducing the amount of dietary intake and food efficiency ratio. In addition, the 5% HS group showed a significant reduction of serum leptin concentration, while having a beneficial effect on the improvement of lipid metabolism such as increase the serum concentration of adiponectin. However, Hamcho freeze-dried nano powder did not show a weight loss effect. CONCLUSION: Overall data indicated that Hamcho seemed to have anti-obesity effects. In particular, consumption of 5% Hamcho freeze-dried powder might have beneficial effects on body weight, serum adiponectin level, and lipid profiles since it led to reduced body weight and growth of adipose tissues by suppressing dietary intakes. However conduct of further research studies is needed for analysis of active components and biochemical action mechanism of Hamcho.

Five halophytic plant species, Suaeda maritima, Limonium tetragonum, Suaeda australis, Phragmites australis, and Suaeda glauca Bunge, which are native to the Muan salt marsh of South Korea, were examined for fungal endophytes by sequencing the internal transcribed spacer (ITS) region containing ITS1, 5.8S rRNA, and ITS2. In total, 160 endophytic fungal strains were isolated and identified from the roots of the 5 plant species. Taxonomically, all 160 strains belonged to the phyla Ascomycota, Basidiomycota, and Zygomycota. The most dominant genus was Fusarium, followed by the genera Penicillium and Alternaria. Subsequently, using 5 statistical methods, the diversity indices of the endophytes were determined at genus level. Among these halophytic plants, P. australis was found to host the greatest diversity of endophytic fungi. Culture filtrates of endophytic fungi were treated to Waito-C rice seedlings for plant growth-promoting effects. The fungal strain Su-3-4-3 isolated from S. glauca Bunge provide the maximum plant length (20.1 cm) in comparison with wild-type Gibberella fujikuroi (19.6 cm). Consequently, chromatographic analysis of the culture filtrate of Su-3-4-3 showed the presence of physiologically active gibberellins, GA(1) (0.465 ng/mL), GA(3) (1.808 ng/mL) along with other physiologically inactive GA(9) (0.054 ng/mL) and GA(24) (0.044 ng/mL). The fungal isolate Su-3-4-3 was identified as Talaromyces pinophilus.

RNA-seq can help us quickly obtain the whole transcriptome sequences of species under different conditions. Many Unigenes that are assembled by raw reads always do not contain complete open reading frame (ORF). In addition, it also has some redundancy in transcriptome library. Some Unigenes in the library, although belong to one transcript, cannot be assembled without overlapping. We found five incomplete Unigenes annotated ammonium transporter (AMT) from Salicornia europaea transcriptome, in which two Unigenes (Uni4 and Uni5) had identical expression patterns across four transcriptomes. The two Unigenes may come from one transcript. Analyzing the Unigene position of transcript by NCBI blastx, we found that Uni4 and Uni5 respectively located in 5' end and 3' end compared with the reference transcript, and an unknown gap of 120 bp may exist in a hypothetic transcript to which Uni4 and Uni5 both belong. To verify the hypothesis, single forward primer and single reverse primers were respectively designed on Uni4 and Uni5, and a fragment with about 800 bp was generated by PCR. Then it was sequenced and aligned with Uni4 and Uni5. Finally, we assembled a sequence with 1 667 bp, which contains a complete ORF (1 482 bp, coding 494 amino acids). It belongs to amt1 subfamily and was named Seamt1 via the phylogenetic analysis. It was pointed by bioinformatics tools that SeAMT1 protein conformed to the AMT characteristics of other species. This work clustered expression pattern to explore the Unigenes of one transcript, and the feasibility of this method was validated through the other two groups of Unigenes. The handy method will benefit extension and assembling of Unigene in transcriptome, it also helps achieve the complete ORF and gene function.
