The effects of water extract from Atractylodes macrocephala Koidz on biological activity were investigated. The crude water extract of A. macrocephala inhibited the growth of the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185, (3 mm inhibition zone at 300 ㎍/disc). However, it did not show growth inhibition activity against Sreptococcus mutans JC-2 (MIC >1,000 ㎍/mL). This extract was cytotoxic to P388 murine leukaemia cells ATCC CCL 46 P388D1, (IC/sub 50/ 62.24 ㎍/mL at 150 ㎍/disc). These results suggest that water extract of A. macrocephala possesses antitumoral, and antimicrobial activities.

This study was carried out to evaluate cytotoxic effects of Atractylodes macrocephala Koidz. (A. macrocephala Koidz.) extract on NIH 3T3 fibloblast. SK-MEL-3 (HBT 69) and KB (ATCC No, OCL 17) cell lines. Disruptions in cell organelles were determined by 3-(4,5-dimethylthiazol-2-y1)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay. 10.2 mg/ml Concentration of A. macrocephala Koidz. extracts in SK-MEL-3 showed that their susceptibility (sensitivity) to these compounds decreased in the following order ; adriamycin > H₂O > ethyl acetate > ethyl alcohol > chloroform > n-hexane in SK-MEL-3 cell lines ; 5-FU > H₂O > n-hexane > ethyl acetate > ethyl alcohol > chloroform in KB cell lines. In order to develop an antimicrobial agent, A. macrocephala Koidz. was extracted with solvents. The minimal inhibitory concentrations (MICs) of each solvent extract of A. macrocephala Koidz. against microogranisms were also examined. Antimicrobial activities of ampicillin and ketoconazole as references were compared to those of each solvent extract of A. macrocephala Koidz. The antimicrobial activity of the ethyl acetate soluble extract of A. macrocephala Koidz. had growth inhibition activity against S. mutans and P. putida (MICs. 500 ㎍/ml). These results suggest that the ethyl acetate soluble extract of A. macrocephala Koidz. possessed antitumorous and antimicrobial agents

This study was carried out to compare chromosomal characteristics between Atractylodes japonica and A macrocephala. Cytogenetic analysis was conducted based on karyotype analysis and physical mapping using fluorescence in situ hybridization. As a result of karyotype analysis by feulgen staining, somatic chromosome numbers of A. japonica and A. macrocephala were 2n=24. The length. of the mitotic metaphase chromosomes of A. japonica ranged from $0.70\;to\;1.60{\mu}m$ with a total length. of $12.11{\mu}m$ and the homologous chromosome complement comprised six metacentrics, five submetacentrics and one subtelocentrics. On the other hand, the length of the mitotic metaphase chromosomes of A. macrocephala ranged from $0.90\;to\;2.35{\mu}m$ with a total length of $16.58{\mu}m$ and the homologous chromosome complement comprised seven metacentrics and five submetacentrics. The total length of A. japonica chromosomes was shorter than that of A. macrocephala, but A. japonica had one subtelocentrics (chromosomes 4) different from A. macrocepha1a. chromosomes. The F1SH technique using 17S and 5S rDNA was applied to metaphase chromosomes. The signals for 17S rDNA were detected on the telomeric regions of chromosomes 4 and 5 in both A japonica and A. macrocephala. The 5S rDNA signal was found in the short arm of chromosome 1.

The effects of the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture on the activities of osteoblast differentiation and the restraint of osteoclast formation were investigated. the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture in the human osteoblast "MG-63" cell, was examined in relation to alkaline phosphatase (ALP) activity and alizarin red stains. In order to observe the effects of osteoclasts formation, we analyzed RAW 264.7 cell tartrate-resistant acid phosphatase (TRAP) activity and TRAP stains. In cytotoxicity testing, it was confirmed that apple extract is safe at a concentration of 50 ㎍/㎖ or less. The ALP activity and Bone calcification formation ability were the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture had a lower activity than that of control group. However the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture significantly reduced activity of TRAP in the RAW 264.7 osteoclastic cell generation and effectively Inhibited the TRAP(+) multinuclear cells. Thus, our results demonstrate that the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture enhances the inhibitory activity of bone-resorption in RAW 264.7 cells. In conclusion, the Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi mixture seem to be effective in the prevention and treatment of bone related disorders.

Background: In September 2017, wilting and rhizome rot symptoms were observed on Atractylodes macrocephala Koidz. in Jecheon-si and Eumseong-gun. This study was carried out to isolate hitherto unidentified pathogenic fungi from A. macrocephala and to test the pathogenicity of isolated fungi against Atractylodes spp. genus such as A. macrocephala, A. japonica, and their interspecific hybrids. Methods and Results: The diseased plants were washed with running tap water, and the boundary between the healthy area and the diseased area was cut while the pathogens were isolated by growing cultures from the diseased areas on Phytophthora semi-selective medium. The internal transcribed spacer (ITS) region of the isolates was used in this study for identification. Test plants were cultivated in the glasshouse at 20℃ - 30℃ for 4 months and then used for pathogenicity test. The pots with plants inoculated with mycelial plugs and zoospores were placed at 25℃ for 48 h in a dew chamber where relative humidity was above 95%, and then moved into the glasshouse at 20℃ - 30℃. The presence or absence of pathogenicity of the strains was determined by evaluating the symptom of plant wilting. The inoculation test was performed in three replicates with a non-treated control. Conclusions: On the basis of results of ITS sequence analysis, the strains isolated from the diseased plants was identified as Phytophthora sansomeana. Biological assay using test plants confirmed the pathogenicity of P. sansomeana against Atractylodes macrocephala. This is the first report of rhizome rot in A. macrocephala caused by P. sansomeana.

This study was conducted to determine the appropriate fertilization level for growing one year old rhizome of Atractylodes macrocephala KOIDZ. According to N and K amounts were increased, the growth of above-ground parts was decreased but P was increased at this time. Based on N-P-K levels, application of 8-9-3 kg/10a was the most effectiveness for the growth of above-ground part, and 8-3-3 kg/10a for that of underground part. It can be estimated that 6-4-6 kg/10a treatment based on N-P-K may be the optimum fertilization level to obtain the highest yield of Atractylodes macrocephala KOIDZ using one year old rhizome.

Astragalus membranaceus Bunge (黃?), Atractylodes macrocephala Loidz (白朮), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子), Ligustrum lucidum Ail (女貞子) are Herbs that are frequently used in a lot of prescriptions to reduce the side effects of anti-cancer therapies, especially like chemotherapy and radiotherapy. The radioprotective and hemopoietic effects of these Herbs on BALB/c splenocytes and bone marrow cells are measured. In order to evaluate the Hemopoietic effects, Thymidine uptakes and secretion of colony stimulating factors(CSFs) of splenocytes and myelocytes treated with herbs were measured. Radioprotective effects were accessed by the method of immunocompetence of murine lymphocytes cultured with herbs before irradiation and with LPS, ConA after irradiation. The results are as follows. 1. The orders of Proliferative effects of herbs on splenocytes were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸). Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all. At Optimal concentration, the proliferation ratios of herb-treated splenocytes compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 44.3, Astragalus membranaceus Bunge (黃?) 17.7, Angelica sinensis(Oliv) Kiels (當歸) 10, Lycium chinense Mill (枸杞子) 6.4, Ligustrum lucidum Ait (女貞子) 2.0.(p<0.05) 2. When splenocytes were cultured during different periods, Atractylodes. macrocephala Loidz (白朮) and Astragalus membranaceus Bunge (黃?) showed the higest proliferation on 3th day, Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) on 4th day,(p<0.05) and Ligustrum lucidum Ait (女貞子) until 5th day but with no significant increase. 3. The orders of Proliferative effects of herbs on Bone Marrow(BM) cells were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus memhranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all too. At Optimal concentration, the proliferation ratios of herb-treated BM cells compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 21.7, Astragalus membranaceus Bunge (黃?) 9.9, Angelica sinensis(Oliv) Kiels (當歸) 4.9, Lycium chinense Mill (枸杞子) 2.3, Ligustrum lucidum Ait (女貞子) 1.4(p<0.05). 4. The secretion ratio of colony stimulating factors(CSFs) of each herb-treated group, compared to control, was Atractylodes macrocephala Loidz (白朮) 9.4, Astragalus membranaceus Bunge (黃?) 9.0, Angelica sinensis(Oliv) Kiels (當歸) 4.4, Lycium chinense Mill (枸杞子) 3.8 (p<0.05) but no significant increase in Ligustrum lucidum Ait (女貞子). 5. The mitogen(ConA, LPS) stimulated-lymphocytes cultured with each herb before irradiation of 1-3 Gy showed more enhanced proliferation than control(p<0.05). When compared to each non-irradiated group of all groups, the orders of percentage increase of irradiated group were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Ligustrum lucidum Ait (女貞子), Lycium chinense Mill (枸杞子). Each percentage showed significant enhancement compared to control group(p<0.05). According to the results, Atractylcdes macrocephala Loidz (白朮), Astragalus membranaceus Bunge (黃?) are suggested to be the most effective hemopoietic and radioprotective herbs, and Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) the next, but Ligustrum lucidum Ait (女貞子) showed lower effects than expected.

Finding a means to discriminate the commercial herb medicines when they were dried and sliced is a very important and imminent project in Korea. To differentiate plant origins and the commercial herb medicines of Atractylodes japonica and A. macrocephala, two discriminative methods using anatomical characteristics and SCAR marker were applied. It was possible to discriminate plant origins and the commercial herb medicines between A. japonica and A. macrocephala by anatomical characteristics: development of periderm, layer of stone cell, distribution of laticiferous vessels, development of xylem fiber in xylem ray, contained quantity of clustered crystals and others. While, two SCAR markers were developed from RAPD clones: SAjR2 (600 bp) from AjR2 and SAmR1 (1,200 bp) from AmR1. These two markers were enough for discrimination plant origins and the commercial herb medicines between A. japonica and A. macrocephala. The result of application of anatomical characteristics and SCAR markers to investigate current status in domestic herb market, Daegu and Kumsan herb market, it was identified to be current herb medicines of A japonica.

The fish community structure and inhabiting status of the endangered species Gobiobotia macrocephala and G. brevibarba were investigated at 10 stations in the Seom River, Korea from spring to autumn in 2010. During the survey, 37 species belonging to 10 families were found as inhabitants. A dominant species was Zacco platypus (36.2%), subdominant species were G. macrocephala (13.2%) and G. brevibarba (12.2%), and predominant species were Coreoleuciscus splendidus (8.1%) and Rhinogobius brunneus (4.9%). In addition, 18 species were endemic species to Korea; G. brevibarba and G. macrocephala were endangered species. The similarity index based on species composition and numbers clearly separated fish communities in the Seom River according to main sections, i.e., upper section (St. 1~3), middle section (St. 4~6) and lower section (St. 7~10). Dominance index gradually decreased toward the lower section, while diversity and species richness index gradually increased toward the downstream section. G. macrocephala resided in a fast-running downstream riffle with pebble and cobble substratum, while G. brevibarba inhabited the entire riffle with cobble substratum.
