Multicellular network analysis is a method for topological properties analysis of cells. The functions of organs are determined by their inner cells. The arrangement of cells within organs endows higher-order functionality through a structure-function relationship, though the organizational properties of these multicellular configurations remain poorly understood. Multicellular network analysis with multicellular models established by 3D scanning of plants, will further discover the plant development mechanism, and provide clues for synthesizing plant multicellular systems. In this paper, we review the development of multicellular models, summarize the process of multicellular network analysis, and describe the development and application of multicellular network analysis in plants. In addition, this review also provides perspective on future development of plant multicellular network analysis.

4.Soil analysis in some medicinal plant growing areas
Journal of Medicinal Materials - Hanoi 2003;8(2):65-69
Soil samples were collected in the provinces of Hai Duong and Thanh Hoa, and in Ha Noi, Da Lat and Sapa cities. Each sample was taken from 9 spots of soil situated on 2 diagonals, that were mixed together. The chemical composition of the soil varied widely in different ecological areas. All the samples of soil showed light acid reaction, while those taken from Sapa (province of Lao Cai) were the most acid. Ha Noi soil samples were neutral. Almost soil samples were poor in total N, P and K, except that of Sapa, which was rich in N, while samples taken from Ha Noi and Thanh Hoa were the poorest. The total amount of P and K varied from poor to medium.

5.The characteristic medicinal plants in treatment of common diseases of people at Thuy Xuan communes, Hue City
Journal of Vietnamese Medicine 2003;291(12):60-64
In the Commune Thuy Xuan (Hue city), 100 randomly chosen households using medicinal plants were interviewed. Results showed a good knowledge and wise, proper safe and practical use of common medicinal plants such as lemon, citronella, ginger, and some other vegetables for treating usual conditions – fever, cold, diarrhora, cough, etc

6.Streptocaulon juventas (Lour) Merr., Asclepiadaceae
Pharmaceutical Journal 1998;272(12):11-13
Total glue or extraction juice, which were made from Streptocaulon juventas (Lour) Merr., Asclepiadaceae in benzene segmentation, increased survival rate of experimental mice with copperhead venom intoxication is from 30% to 60% and prolong the resistant time from 2.4 to 9.8 time in comparison with placebo. Effect of glue is more strong than extraction juice in benzene segmentation. Model of copperhead venom intoxication is nearly with common intoxication, and intoxication due bacteria and allergy. Thus experimental result suggested for previous studies about detoxicated effect and antiallergy of this medicinal plant.

Eleven compounds (1–11) were isolated from the rhizomes of Osmunda japonica, and their structures were elucidated based on 1H, 13C-NMR and LC-IT-TOF MS data. Of these compounds, all compounds (1 – 11) have been previously reported, although five (6 – 9, 11) have not previously been isolated from this plant. The antioxidant activities of isolated compounds (1 – 11) were measured by DPPH and ABTS assays, and compound 10 showed the high antioxidant activity.

Aims:
Plant diseases caused by pathogens are threatening crop yield. Agrochemicals are used extensively to curb pathogens. Efforts to reduce the usage of agrochemicals are needed for sustainable agriculture. This study was aimed to screen medicinal plants possessing antifungal properties against crop pathogenic fungi.
Methodology and results:
Sequential extraction using absolute n-hexane, ethyl acetate and methanol was performed on nine selected medicinal plants to obtain crude extract. An antifungal assay using these crude extracts was performed on Fusarium solani, Collectotrichum musae and two isolates of Pyricularia oryzae. The assay showed that medicinal plant species with all three types of crude extract inhibited the growth of all three pathogenic fungal species tested. The inhibitory effects of crude extracts were not only fungal species dependent but also isolate dependent.
Conclusion, significance and impact of study
Antifungal effect of nine selected medicinal plant species was observed against the three tested fungal pathogens. These research findings suggest that the selected medicinal plant species may serve as a potential source for the development of new biofungicide products.

Aims:
Acalypha indica (AI), Centella asiatica (CA), and Sesbania grandiflora (SG) are vegetables commonly used in
traditional medicine in Asian countries to treat skin problems. In this study, we investigated their pharmacological
activities relevant to wound healing and synergistic actions to provide an insight into a promising vegetable combination
as a candidate treatment for wounds.
Methodology and results:
The stimulatory, antioxidant, and antibacterial activities of aqueous (A) and methanol (M)
extracts of all the three vegetables were assessed alone and in combination in normal human dermal fibroblast (NHDF)
cells in vitro. CA-A (89.52%) and the combination of AI-A+CA-A (90.76%) produced the highest percentage of wound
closure. AI-A exhibited the highest total phenolic content (TPC) (82.94 mg GAE/g) and moderate reducing activity (61.63
mM Fe (II)/mg) when assessed by ferric reducing antioxidant power (FRAP) assay. Free radical scavenging activity was
evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), and
the combination of AI-A+CA-A exhibited scavenging activity at IC50 = 379.75 µg/mL and IC50 = 578.7 µg/mL,
respectively. Pre-treatment of NHDF cells with CA-M at 100 µg/mL offered the highest protection against hydrogen
peroxide. All single and combined vegetable extracts showed poor antibacterial properties against Gram negative and
Gram positive bacterial species implicated in wound infection. Only AI-A+CA-A executed synergism in fibroblast
migration when assessed via the combination index (CI). Furthermore, screening and identification of AI-A, CA-A, and
CA-M via UHPLC (LC-MS/MS) system revealed that the major components responsible for all the tested bioactivities
were phenolic groups such as simple polyphenols, flavonoids, polysaccharides, and triterpenes (asiaticoside and
madecassosides).
Conclusion, significance and impact of study
The vegetable extracts of A. indica, C. asiatica, and S. grandiflora
exhibited good bioactivities independently. However, only AI-A+CA-A showed synergism in combination to accelerate
the migration of fibroblast and increase antioxidant activities. These findings demonstrate the potential formulation of
combined vegetable extracts from the two species of A. indica and C. asiatica for optimum wound healing properties.
