  • This study compared quality changes among brined baechu cabbages manufactured by various salting methods and types of salt. Brine, brine and dry salting, and dry salting were used as salting methods. When baechu cabbages were salted by dry salting method, the salinity of brined baechu cabbage increased compared to salting by other methods, even though the quantity of salt used was small. In addition, salinities of leaf and stem were relatively equal among brined baechu cabbages using dry salting method compared to those of other methods. When baechu cabbages were salted using dry method at different salt concentrations (3%, 5%, and 10% of weight of baechu), brined baechu cabbage showed suitable salinity (1.41~1.42%) at 5% salt concentration. Among brined baechu cabbages prepared using dry salting method with different types of salt (purified salt, solar salt, and bamboo salt), bamboo salt produced the highest salinity. Brined baechu cabbages with solar salt and bamboo salt showed significantly lower counts of total aerobic bacteria and higher counts of lactic acid bacteria than others. These results indicate that baechu cabbage can be salted equally, and the amount of salt used can be reduced when baechu cabbage is salted using dry salting method. In addition, using solar salt and bamboo salt can increase the quality of brined baechu cabbage.

  • For biomass estimation of Phyllostachys pubescens stands by optimal survey method we established 9 bamboo sample plots in the research forests of KFRI (Korea Forest Research Institute). The dry weight of culm segment determined by relative heights of total bamboo height show us two groups of 1st to 5th culm segment (up to 0~55% culm of tree height from the bottom area) and 6th to 8th culm segment (55~100%) by the results of cluster analysis for dry weight ratio. This results show that upper and lower part of 55~70% reference height from the bottom area against total culm height can be used in obtaining 1 kg of a sample bamboo, respectively, rather than 2.0 m stem segments of other forest tree species. In above-ground biomass estimation by $W=aD+bD^2$ having the highest coefficient of determination in this study, above ground stand biomass was 57.77 ton/ha (culm 40.47 ton/ha, branch 9.29 ton/ha, and leaf 8.01 ton/ha) of which 70% was contributed by culm component followed by branch (16%) and leaf (14%). Below-ground biomass was 53.35 ton/ha in total.

  • An exploratory study was conducted in Juri Forest Range-2, a proposed biodiversity conservation area of Bangladesh to explore the present growing stock of tree, regeneration condition and status of non-timber forest products (NTFPs). This conservation area contains both natural and artificial plantation was selected by using multistage random sampling method. For determination of plot size and sampling methods, the quadrate size ($10m{\times}10m$) for tree stock measurement, ($2m{\times}2m$) for regeneration survey, ($20m{\times}20m$) for NTFPs survey was determined. Regarding tree stock survey, 14 species under eight families were found where Tectona grandis shows average number of stem/ha was 624 and basal area/ha was (10.36 $m^2/ha$) followed by Acacia auriculiformis (0.2 $m^2/ha$ and 637 stem/ha), Gmelina arborea (0.2 $m^2/ha$ and 600 stem/ha). In regeneration survey, 14 species were found belonging to 9 families where Alstonia scholaris shows highest (3,750) seedling per hectare. Regarding NTFPs, bamboo and cane are the most common resources. In last ten years, the total timber output was 1,28,596.14 cubic feet and total amount of revenue was 4,64,434 US$. The vacant area is 1,335.5 acre which contains 14% of total area. If this vacant area is planted with suitable species and take proper steps for appropriate management of this species it will be a good biologically diversified area.

  • Classwort (Salicornia herbacea L.), a halophyte, is a potential functional food resource in Korea. This study was conducted to determine the antioxidant activity of glasswort, as a functional food material, on the lipid oxidation of pork. To compare antioxidant effect of different parts of glasswort, samples such as dried ground leaves, stems, and roots of glasswort were prepared. The antioxidant activity was determined by the TBARS(Thiobarbituric Acid Reactive Substances) method. Freeze-dried leaves of glasswort at 0 day of storage had the lowest TBARS values, suggesting the highest antioxidant effect. But the antioxidative effect of freeze-dried leaves of glasswort was less than that of BHT. At 7 days after storage, however, the values were not different from oven-dried leaves. The oven-dried leaves at 14 days after storing should highest antioxidative activity. In conclusion, antioxidative effect of glasswort was apparently exhibited through measurement of TBARS. Antioxidative effect from ground leaf sample of glasswort harvested in coastal region was the highest, followed by root and stem samples. Glasswort had twice as high antioxidative effect as sea salt and bamboo salt.

  • The pharmacological mechanisms of most Oriental medicines have not been clearly defined in spite of their effective use in treating many diseases throughout the world. Many Oriental medicines have been used against various allergic diseases for generations, and still occupy an important place in traditional medicine in far eastern countries including Korea. It is also still unclear how Oriental drugs prevent allergic disease in vivo or in vitro models. Some Korean folk medicine inhibited the mast cell-mediated allergic reaction. This review summarizes the effective folk medicine in experimental effect on systemic or local anaphylaxis reaction. Potential anti-anaphylactic folk medicines include: Poncirus trifoliata; Siegesbeckia glabrescence; Solanum lyratum; Aquilaria agallocha; Ulmi radicis; Polygonum tinctorium; Hwanglyun-Haedok-Tang; Rehmannia glutinosa; Kum-Hwag-San; Syzygium aromaticm; Spirulina platensis; Sosiho-Tang; Sinomenium acutum; Schizonepta tenuifolia; Shini-San; Magnoliae flos; Sochungryong-Tang; Oryza sativa; Cryptotympana atrata; Salviae radix; Rosa davurica; Asiasari radix; Chung-Dae-San; Cichorium intybus; Perilla frutescens; Vitex rotundifolia; Terminalia chebula; Siberian Ginseng; Solanum melongena; Gahmi-Shini-San; Alpinia oxyphylla; Acanthopanax senticosus root; Prunella vulgaris; Allergina; Ixeris dentate; Acanthopanax senticosus stem; Tongkyutang; Salvia plebeia; Rubus coreanus; Sinpo- Tang; Dodutang; Forsythia fructus; Xanthii fructus; and Purple bamboo slat. Ensuring the effects and understanding the mechanisms of action for these Oriental medicines can permit drug development and laying of the ground-work for evaluating potential synergistic effects by addition and subtraction of prescriptions.

  • Jukyeo (竹茹; Bambusae Caulis in Taeniam: BCT) is an herbal medicine made from the inner part of the bamboo stem of Phyllostachys nigra Munro var. henonis Stapf ex Rendle or Phyllostachys bambusoides Siebold et Zuccarini. Although medical literature published in China and Korea decades ago introduced BCT as a remedy for reducing vomiting, fever, and hematemesis, decoctions containing BCT as a main herb (君藥) in Korea have been approved only for treating neurologic symptoms. Here, we discuss the anti-inflammatory function of BCT. Combined with the clinical usage of a BCT-containing decoction in treating inflammatory diseases in Japan, we raise the possibility of repurposing the BCT-containing decoctions for treating inflammatory diseases. The anti-inflammatory activity of BCT was mainly assessed by using RAW 264.7 cells. The regulation of NF-κB, Nrf2 and A20 activities was determined by western blot and quantitative RT-PCR. The list of decoctions containing BCT currently approved in Korea was obtained from the Korean Ministry of Food and Drug Safety (KFDA). BCT suppressed the activity of pro-inflammatory factor NF-κB elicited by LPS, activated an anti-inflammatory factor Nrf2, and induced A20 that is known to block several inflammatory pathways simultaneously, suggesting that BCT can suppress inflammation via at least 3 different pathways. KFDA approved 11 decoctions containing BCT as a major herb, including Gamiondam-tang (加味溫膽湯; GOT), for treating neurologic disorders. Interestingly, Jukyeoondam-tang (竹茹溫膽湯; JOT), whose composition is almost identical to GOT except for one herb, has been used to treat inflammatory pulmonary disorders including Covid-19 pulmonary infection in Japan Given the anti-inflammatory function of BCT evidenced by medical literature and experimental results and the clinical usage of JOT in treating inflammatory pulmonary disorders, we suggest a repurposing and extension of the BCT-containing decoctions approved in Korea to treating inflammatory diseases.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.
