  • Persimmons on the trees are often exposed to weather condition of cold temperature before harvest, which affects the fruit quality at harvest time and later storage. This study investigated the effect of the harvest season temperature on the storage quality of 'Fuyu' sweet persimmons. Monitoring the temperature changes in the orchard showed five times of cold temperature below the freezing temperature of persimmon, $-2.1^{\circ}C$, in the harvesting period between mid October and mid November with the lowest being as low as $-5.4^{\circ}C$. Among three different harvestings, the tertiary one at mid November showed decreased 'L' value and consistently high 'a' value of color index and high reduction in hardness during 150 days storage of fruits at $0^{\circ}C$ showing freeze-injured symptoms, compared to the first one at mid October and the second one at early November. The fruits of first harvest maintained consistently hard texture with increased 'a' color value probably due to postharvest ripening. The tertiary harvest exhibited increase in fructose and glucose contents and decrease in sucrose of the fruits, being very different from the first and secondary harvests which maintained constant level of all three free sugars. Mid November with possible sudden temperature drop is unsuitable period for harvesting sweet persimmons in the quality at harvest and later storage, and thus the harvest should be designed to be done before that time.

  • Objective: The purpose of this study was to investigate acute and subacute toxicity and sarcoma-180 anti-cancer effects of Herbal acupuncture with Anneniacae amarum semen (Haeng-in) in mice and rats. Method: Balble mice were injected intraperitoneany with Haeng-In extract for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were injected intraperitoneally with Haeng-In extract for subacute toxicity test. TheAnneniacae amarum semen Herbal-Acupuncture was injected on Chung-wan (CV12) of mice with Sarcoma-180 cancer cell line. Results: 1. $LD_{50}$ was uncountable as none of the subjects expired from the treatment groups during the test. 2. The clinical signs and the body weight of mice treated with 0.1cc and 0.2cc Haeng-In extract were not affected during the acute toxicity test. 3. In acute toxicity test of serum biochemical values of mice, total protein and albumin were decreased in treatment group Ⅰ. Glucose was increased, and total cholesterol was decreased in treatment groups. GPT was increased in treatment group Ⅰ. 4. In subacute toxicity test, toxic symptoms were not detected in the treatment groups. 5. In subacute toxicity test, the body weight was increased in treatment groups on 14th and 21st day. 6. In subacute toxicity test. liver weight was increased in treatment group Ⅱ, and spleen weight was increased in treatment group Ⅱ. Lung weight was increased in an the treatment groups.(p<0.05) 7. In subacute toxicity test, severe tissue injury was found in lung and liver, especially treatment group Ⅰshowed more significant lung damage compared to treatment group l. 8. In subacute toxicity test, WBC. MCH and MCHC were increased in an the treatment groups, RBC, HGB and HCT were decreased in treatment group H(p<0.05). 9. In subacute toxicity test of serum biochemical values of rats, triglyceride was decreased in all the treatment groups. ALP was decreased in treatment group Ⅰ. and creatinine was decreased in treatment group Ⅱ. BUN/CR was increased in treatment group Ⅱ(p<0.05). 10. Median survival time of Sarcoma-180 cancer cell treated with Haeng-In was increased in all the treatment groups by twenty percent, compared to the control group(p<0.05). 11. Natural killer cell activity about the Sarcoma-180 cell was decreased at the ratio of 100:1 but was increased at the ratio of 10:1. In treatment group Ⅱ, increase was found at the ratio of 100:1 and 50:1 (p<0.05). 12. Interleukin-2 productivity of the Sarcoma-180 cell was decreased in treatment group I, but was increased in treatment group Ⅱ(p<0.05). Conclusion: According to the results, we can conclude Herbal-acupuncture with Anneniacae amarum semen caused toxicity, and had effects in Sarcoma-180 cancer cell.

  • This study was performed to investigate the medicinal effects of the herbal combination extracts-2 (HCE-2), consisting of Artemisia capillaris Thunb., Lonicera japonica Thunb., Prunella vulgaris var. lilacina, and Hovenia dulcis Thunb. on the alcohol-induced liver injury in rats. The rats were randomly divided into four groups: normal group (n =6), non-treated control group (n =6), saline-treated group (n =6) and the herbal combination extract (HCE-2)-treated group (n =6). The rats in the alcohol-loaded groups were orally administered with ethanol at a daily dose of 4 g/kg-body weight for 5 weeks. Thirty minutes before the ethanol injection, saline or herbal combination extracts was administered by using a gastrogavage. Blood and liver tissue samples were taken out from the hearts and livers of the rats, respectively, on 15th and 38th days. The activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured using an enzyme-linked immunosorbent assay (ELISA). We also investigated the protective effect of the herbal combination extracts by Hematoxylin-Eosin staining on histological sections of rat liver. In this study, the oral administration of the herbal combination extracts significantly reduced the serum levels of AST and ALT, which had been raised by alcohol-induced liver injury. Histological analysis and apparent observation of liver also showed the preventive effect of the herbal combination extracts in a chronic alcohol-induced rat model. Theses results revealed that the herbal combination extracts effectively prevented hepatic damage consequent to the chronic exposure to repetitive administration of ethanol and could be used as a primary resource of a health beverage or herbal medicine, alleviating the alcohol-induced hepatic injury and hangover symptoms.

  • Objectives : A common cold is a viral disease. There exists only allopathy for it depending on symptoms because of no cure. Korean medicine has taken a serious view of common cold patients with digestive problems as well as patients of the common cold. Accordingly, this study is aimed at finding out the traits of patients with digestive problems among common cold patients. Methods : A survey was conducted with 62 cold patients who got medical treatment in Korean medicine clinics located in small cities and towns including metropolitan cities. The SPSS for Windows( 19.0 Version) was used for statistical analysis. Results : Depending on which clinic common cold patients decided to go to, there was a significant difference in the number of sick days. The group of patients who decided to go straight to oriental medicine clinics had fewer sick days. Only 9.7% of the group of patients who got treatment in Koean medicine clinics had more than 6 sick days. The group of common cold patients with digestive problems had more sick days than the group with no digestive problems, which showed that there was a significant correlation between digestive problems and sick days. When it came to digestive problems depending which clinic common cold patients decided to go to, there was no significant value because of little data collection. However, while 41.9% of the group who went to hospital at first and then to Koean medicine clinic had digestive problems, 24.2% of the group who directly went to Koean medicine clinic had digestive problems. On the whole, 66.1% of the entire common cold patients were shown to have digestive problems. Conclusion : There are relatively many patients with digestive problems among common cold patients, and there is a significant correlation between digestive problems and sick days on common cold.

  • Objectives: Chunghyul-dan is a combinatorial herbal medicine, and previous studies reported it had therapeutic effects for microangiopathy, which is a major part. in the progression of stroke, as well as having anti-hypertensive, anti-hyperlipidemic, anti-apoptotic, anti-oxidative, and anti-inflammatory activities, Therefore, we examined the inhibitory effect of Chunghyul-dan on stroke occurrence in patients with silent brain infarction. Methods: We prescribed Chunghyul-dan at 600 mg a day to patients with silent brain infarction confirmed by brain MRI, and monitored stroke occurrence, drug compliances, and adverse effects for 1 year, We then performed follow-up brain MRI to detect new vascular lesions after 1 year of Chunghyul-dan medication. As for the subjects lost to follow-up, we assessed their prognosis after 1 year by telephone. Results: There were twenty-one subjects who were treated with Chunghyul-dan for more than 1 year, None of them experienced new clinical syndromes characterized by rapidly developing clinical symptoms and signs of focal and at times global loss of brain function, which could be accompanied with evidence of stroke occurrence, or any adverse effects during the Chunghyul-dan medication period. These results might be explained by various biochemical effects of Chunghyul-dan on microangiopathy, which is closely related with cell cycle progression, hypertension, hyperlipidemia, vascular inflammation, and oxidative damage. Of the 10 subjects lost to follow-up, six were reached; two of them had stroke occurrence. Conclusions: We suggest Chunghyul-dan could be useful for prevention of stroke occurrence in patients with silent brain infarction by preventing the progression of microangiopathy. Further study with a randomized controlled trial is needed to confirm this suggestion.

  • Objectives: Moxa treatment has outstanding effects that are frequently facilitated in a clinical setting, and it is also known to have positive effects for immunity and relief of pain through various studies. Currently, moxa treatment has become diversified in many ways. One of the moxa treatment techniques that was frequently used during the Joseon Dynasty was Woogakgubeop (牛角灸法, horn-shaped moxa treatment). This articles aims to disclose the fact that the Woogakgubeop is the technique applicable to the origin of the Large moxa treatments of today. Also, the writings of Woogakgubeop recorded in the royal medical documentations, such as the Chronicles of the Royal Families of the Joseon Dynasty, the Seungjeonwonilgi (The Daily Records of Royal Secretariat) and others, are analyzed and the characteristics of the Woogakgubeop are cleared through it. Methods: From the royal medical documents, the Chronicles of the Royal Families of the Joseon Dynasty and the Seungjeonwonilgi, articles related Woogakgubeop were extracted and analyzed. Records of each document were facilitated for the DB search. In addition to these two documents, the records of written literature were surveyed as well. The written literature are appropriate to express the experiences of intellectuals at the time. Results and Conclusions: 1. Considering that Woogakgubeop is a single therapy, there exists relatively many records in addition to the specialized medical documents, and through them, it is known that Woogakgubeop was a widely known therapy in the middle to later parts of Joseon in general. 2. Woogakgubeop is a method that addresses problems contained within the existing moxa treatment techniques. By enlarging the size of the mugwort wick, it strengthens the heat energy of the moxa treatment to reduce the frequency of applying moxa treatment. When undertaking the method to empty the wick inside the mugwort, the pain of a fever patient will be reduced and burn damage to the skin is minimized. 3. Wind-cold type weakness and other general moxa treatment techniques have been used for various symptoms detailed, including chest pain, tinnitus, carbuncle, cellulites, cold sense of leg, colic, diarrhea and other illnesses. In addition, it may generate strong fever, and was used to implement the Yeonjebeop (煉臍法). 4. Woogakgubeop is applicable to the origin of Large moxa treatment of today and it provides important bibliographic base thereof.

  • Bacterial fruit blotch (BFB) is one of most important diseases in Cucurbitaceae due to infection of Acidovorax citrulli, causing huge economic losses damage worldwide. This seedborn disease spread rapidly at period of high temperature and humidity. The eco-friendly farming is getting popular. So far there was no effective agent to control BFB in eco-friendly farming. Therefore, effect of the material based on chinese nut-gall extract with antibacterial activity against BFB to was tested against A. citrulli. Different hosts showed various symptoms of BFB. Liquid formulation among exhibited most effective anti-bacterial activity on A. citrulli. Pot experiment in greenhouse showed the potential as an control agent of BFB in cucurbits. The treatment of material based on chinese nut-gall extract showed the positive effect on survival of the watermelon seedling and on the length of the cucumber seedling treated with A. citrulli. We cautiously conclude that the material based on chinese nut-gall extract used in this study may be good agents against major diseases of cucurbits in the future even though it is require to be tested with more study on field test.

  • Plastic bronchitis is a rare disease characterized by the recurrent formation of branching mucoid bronchial casts that are large and more cohesive than those that occur in ordinary mucus plugging. Casts may vary in size and can be spontaneously expectorated, but some require bronchoscopy for removal. Plastic bronchitis can therefore present as an acute life-threatening emergency if obstruction of the major airways occurs. Three of 22 reported patients with eosinophilic casts were fatal, with death due to central airway obstruction. Here, we report a child with no history of atopy, allergy, or congenital heart disease who was diagnosed with plastic bronchitis with eosinophilic casts. Although he was administered intravenous (iv) antibiotics; iv corticosteroids; and a vigorous pulmonary toilet regimen, including chest physiotherapy and routine bronchoscopic removal of casts, he had brain death secondary to hypoxic brain damage. Plastic bronchitis can be fatal when casts obstruct the major airways, as in the present case. Clinicians should intervene early if a patient exhibits signs and symptoms consistent with plastic bronchitis.

  • Recently, bacterial angular leaf spot disease, caused by Xanthomonas fragariae, causes severe damage in strawberry production and its' export to other countries, since the pathogen has been classified as an A2 quarantine pathogen. Typical the Angular Leaf Spot (ALS) disease represent that water-soaked angular spots symptoms, bacteria ooze exudate under relatively high humidity condition and later the spot become reddish brown on the leaf surface. The pathogen disseminated by irrigation water, infected mother plant and farmer's hand. In this study, we reported that rubbing inoculation method showed more effective in the pathogen dissemination than infiltration with needles, regardless the strawberry cultivars. Additionally, Dichloroisocyanurate (NaDCC) treatment in commercial strawberry fields provided reliable efficiency to reduce the bacterial angular leaf spot disease incidency and severity.

  • 1. Objective: This literary review investigates Lee Jema's clinical experiences with Soyang-type patients and their influence on his conceptualization of the Soyang physiology and pathology. 2. Methods: 1) The case reports in "Soyang constitutional type: Spleen Cold-based Exterior-Cold disease" were compared before and after the Sinchuk revision to explore the temporal change in the Sasang medical concepts. 2) The texts in Donguisusebowon (Gabo edition) and Donguisusebowon (Sasangchobongwon) were analyzed to investigate the pathological concepts appearing before the completion of the Donguisusebowon (Gabo edition). 3) The texts in Donguisusebowon (Sinchuk edition) was analyzed to investigate the pathological concepts formed between the Gabo and Sinchuk editions of Donguisusebowon. 3. Results and Conclusions: 1) Gabo edition : The Gabo edition divided the External-origin Exterior disease into Cold-dominant (Heat-moderate) and Heat-dominant (Cold-moderate) patterns and differentiated the severity of Exterior-based Exterior disease and Interior-based Interior disease into mild, moderate, severe, and critical conditions. Cold-damage Delirium disease pattern was categorized as an Interior-based Interior disease, and the treatment protocol using Baekho-tang (Baihu-tang) was established. The stool condition and bowel movement reflecting the patient's defecation habits, the prime indicator of health in the Soyang constitutional type, were emphasized on their importance. 2) Sinchuk edition: The Delirium disease pattern was moved into the Exterior-cold disease, and the treatment protocol applying Jihwangbaekho-tang (Dihuangbaihu-tang) and Hyeongbangsabaek-san (Jingfangxiebai-san), with variational usage of Gypsum, was newly established. The Seong-Jeong and basal disease patterns were suggested as important factors in treating the patients. Also, it was proposed that the symptoms and signs reflecting the condition of the life-preserving energy be assessed to understand the patient's current condition. The importance of post-acute rehabilitation and aftercare as well as the most appropriate acute-stage treatment were emphasized.
