Erwinia amylovora is a causative pathogen of fire blight disease, affecting apple, pear, and other rosaceous plants. Currently, management of fire blight relies on cultural and chemical practices, whereas it has been known that few biological resources exhibit disease control efficacy against the fire blight. In the current study, we found that an SFC20201208-M01 fungal isolate exhibits antibacterial activity against E. amylovora TS3128, and the isolate was identified as a Penicillium brasilianum based on the 𝛽-tubulin (BenA) gene sequence. To identify active compounds from the P. brasilianum culture, the culture filtrate was partitioned with ethyl acetate and n-butanol sequentially. From the ethyl acetate layer, we identified two new compounds (compounds 3-4) and two known compounds (compounds 1-2) based on spectroscopic analyses and comparison with literature data. Of these active compounds, penicillic acid (1) exhibited promising antibacterial activity against E. amylovora TS3128 with a minimal inhibitory concentration value of 25 ㎍/ml. When culture filtrate and penicillic acid (125 ㎍/ml) were applied onto Chinese pearleaf crab apple seedlings prior to inoculation of E. amylovora TS3128, the development of fire blight disease was effectively suppressed in the treated plants. Our results provide new insight into the biocontrol potential of P. brasilianum SFC20201208-M01 with an active ingredient to control fire blight.

Nowadays people suffer from the excessive stress, emotional disorder, lack of sleepness, overeating of rich fatty diet and irregular schedule. These things accumulate Fire inside humanbody through many ways. Fire, then, brings out many kinds of disease. How to treat Fire is important theme of the medicine. Liu Wansu studied Fire as a important pathogenic factor. He evolved his theory about the relationship between the Xuanfu(玄府)- the sweat, Six Qi, emotional disorder and the climate condition and Fire. He payed great efforts to diagnose accurately and treat the disease on the ground of the theory based on The Yellow Emperors‘ Internal classic.

Fire blight, caused by Erwinia amylovora(Burrill), is a destructive disease of apple that damages blossoms, shoots, and woody plant organs. The fire blight disease is a worldwide problem for pome fruit growers because all popular apple cultivars are susceptible to the disease. Recently, fire blight of apple rootstocks has become a serious economic problem in high-density orchard systems in korea. The most commonly used dwarfing root stocks, M.9 and M.26, are highly susceptible to E. amylovora. The objective of the apple rootstock-breeding program has been to develop pomologically excellent rootstocks with resistance to abiotic and biotic stresses, including fire blight. Budagovsky 9 (B.9) apple rootstock is reported to be highly susceptible when inoculated with E. amylovora, although results from multiple trials showed that B.9 is resistant to rootstock blight infection in field plantings. So we tried to collect the apple rootstocks traits of fire blight resistance. The apple genotype Malus Robusta 5 (MR5) represents an ideal donor for fire blight resistance because it was described as resistant to all currently known European strains of the pathogen. The PCR for detecting the MR5 gene using the primers Md_MR5_FL_F/Md_MR5_FL_R. The results of these experiments confirmed some apple rootstocks traits of fire blight resistance showed the MR5. Furthermore, this gene is confirmed to be the resistance determinant of Mr5 as the transformed lines undergo the same gene-for-gene interaction in the host-pathogen relationship MR5-E. amylovora.

Erwinia amylovora, a causal bacterium of fire blight disease, is registered as a prohibited quarantine pathogen in Korea. To control the disease, the government should diagnose the disease, dig and bury the host trees when fire blight occurs. Fire blight was the first reported in 43 orchards of Anseong, Cheonan, and Jecheon in 2015, and 42.9 ha of host trees were eradicated. However, the disease spread to eleven cities, so that 348 orchards and 260.4 ha of host trees were eradicated until 2019. Fire blight of Asian pear occurred mainly in the southern part of Gyeonggi, and Chungnam province, on average of 29±9.2 orchards per year. And the age of the infected trees were mostly 20-30 years old. In apple trees, the disease occurred mainly in the northern part of Gyeonggi, Gangwon, and Chungbuk province, on average of 41±57.6 orchards per year, increased highly in 2018 and 2019. The age of infected apple trees were under 20 years old. Therefore, because the disease spread rapidly in young apple trees, spraying control agents to the trees in a timely manner and removing infected trees quickly are important to prevent the spread of fire blight in the orchard of immature trees.

The results of analyzing "Shanghanlun-Shanghan examples" of Song Dynasty Text and Liuwansu's writings in the pursuit of comprehending his views written in "Fire-Heat" & "Warm disease" -are as follow. 1.He introduced Exterior-Interior Shanghan and Latent in the Winter & recurrent in the Spring Shanghan concept in the Febrile disease pathology as the link and the bifurcation point. His perception on Febrile disease encompassed Shanghan and Febrile disease on the same plane but actually discriminated in the treatment and medication between the two actually. 2.He suggested Febrile disease pathology in the concept of Shanghan and Febrile disease, which is coherent in the formation of interior heat as the result of the invasion of the lung by warm pathogen described in Warm disease Wei, Qi, Ying and Xue Fen Syndrome differentiation. He expanded the concept of esoteric portal 玄府 of "Suwon Tiaojinglun", to that of the omni-present portal & way of Qi's all directions movement, which is in accordance of invasion of upper energizer 上焦 by warm or hot pathogen via mouth and nose as used in Warm disease three-energizer differentiation. 3.He recognized both exterior-interior febrile disease in the context of both exterior-interior contact cause disease. He prescribed pungent-cool exterior releasing medicinal similar to that of exterior-releasing treatment adopted in warm disease. As lily-talc powder百合散 introduced in "Golden chamber synopsis" dispells heat by promoting excretion of urine and defecation, it is regarded as the original formula of later ikwonsan yiyuansan 益元散.

This report describes 48 studies related to the use of Bulbus Fritillariae main blended prescriptions from Donguibogam. The following conclusions were reached through investigations on the prescriptions that use Bulbus Fritillariae as a key ingredient. All kinds of infection in a cough and the malignant tumor recorded the largest number of clinical frequency of the prescriptions in therapeutic use when Bulbus Fritillariae was taken as a principle medicine. The Prescriptions are compounded with Bulbus Fritillariae as a principle medicine can aplly to respiratory disease, eye disease, nose and ear disease, throat disease, a boil. Various pathogenic factors such as consumptive disease, phlegm, phlegm-fire, invasion by wind, affective by cold, fire, dyspepsia-fire are put to practical use. The dosage of Bulbus Fritillariae is 5 bun (about 1.88g) to 1 lyang(about 37.5g), however 1 jeon(about 3.75g) has been taken the most for clinical application. With examination the formulae of presciptions containing Bulbus Fritillariae, I found the basic prescriptions as well as the medicines are in conjunction with Bulbus Fritillariae and the theoretic grounds of formula in combining Bulbus Fritillariae as a group of medicine for presciption through this reseach.

Objective: The 19 Mechanisms of Disease were first described in Huangdi Neijing. When examining Yixuexinwu, three descriptions that were different from Huangdi Neijing were found. Methods and Results: After examining the two books, three differences in the description of the 19 Mechanisms of Disease were discovered: 1) The upper and lower locations of dyspnea (喘症) are reversed. 2) The ratio of provisions for "fire (火)" and "cold (寒)" is different. 3) The organ affiliation for pain is different. Conclusion: 1) The upper and lower locations of dyspnea (喘症) are reversed. : Regarding external contraction dyspnea (外感喘), Yixuexinwu used the disease of the upper location (lung 上, 肺) in the same way as in Huangdi Neijing. In terms of internal damage (內傷喘), it was separately classified as a disease of the lower location (kidney 下, 腎). 2) The ratio of provisions for "fire (火)" and "cold (寒)" is different. : Arithmetically, if you round off the number after calculating the fraction, the difference between the two ratios becomes the same. Theoretically, five provisions of "fire" are replaced by four provisions of "heat (熱)", and the difference in ratios is exactly the same. Empirically, it emphasizes that there are more illnesses from fire and heat than from cold. 3) The organ affiliation for pain is different. : Huangdi Neijing described general inflammatory pain, while the Yixuexinwu described only stress-related abdominal pain (肝木乘脾 腹痛).
