There are eight kinds of formulas for invigorating the liver to cure its asthenic syndrome based on the types of preparation formulas Began-tang, Boganhwan, Bogansan, Bogandan, Boganeum, Boganjoo, Boganjeon and Bogango. Another formula called Bocheonghwan is to invigorate the green colour of liver. There are 22 kinds of Bogan-tang, 12 kinds of Boganhwan, 25 kinds of Bogansan, one kind of Bogandan, one kind of Boganeum, one kind of Boganjoo, one kind of Boganjeon, one kind of Bogango, and two kinds of Bocheonghwan. Combination of herbal medicines, carried out in formulas for invigorating the liver, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Bogan-tang for curing the asthenic syndrome of liver through analyzing the component medicines and combination principles of Hyeongok's Bogan-tang, and furthermore, maximizing the clinical use of Began-tang. This study analyzed the component medicines and combination principles of Hyeongok's Bogan-tang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Began-tang is an odd prescription, composed of 7 kinds of ingredients No.1 Radix Angelicas Sinensis (2don;7.5g), No.2 Rhizoma Chuanxiong (1don;3.75g), No.3 Radii Polygoni Multiflori (1don), No.4 Fructus Lycii (1don), No.5 Cortex Cinnamomi (1don), No.6 Rhizoma Gastrodiae (1don), and No.7 Radix Glycyrrhizae (1don). There are three methods for curing the asthenic syndrome of liver according to the five elements doctrine invigorating the liver, invigorating the kidney and purging the lung. First, if you suffer from the asthenic syndrome of the liver, you need to invigorate your liver. There are two available methods, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each imply the pungent taste and the warm property invigorate the liver. In the case of taste invigoration, two herbal medicines with pungent taste, Radix Angelicas Sinensis and Rhizoma Chuanxiong, are combined into the principal and assistant herbal medicine, respectively. For property invigoration, two herDal medicines with the warm property, Cortex Cinnamomi and Rhizoma Gastrodiae, are combined into adjuvant herbal medicines. Secondly, if you suffer from the asthenic syndrome of the liver, you need to invigorate your kidney which is mother in the mother-child relationship in inter-promotion among the five elements. There are two methods to invigorate the kidney, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each mean the bitter taste and the cold property invigorate the kidney. Therefore, it is important to use bitter herbal medicines for taste invigoration and cold ones for property invigoration. Both Differ and cold herbal medicines, Radix Polygoni Multiflori and Fructus Lycii, are combined into adjuvant herbal medicines. Lastly, if you suffer from the asthenic syndrome of the liver, you need to purge your lung which is an element being surpassed in the relationship between the elements surpassed and ones not surpassed in inter-restraint among the five elements. There are two methods to purge the lung, which include taste and property invigoration according to the theory for properties and tastes of herbal medicines. Taste invigoration means to purge the lung with pungent taste and property invigoration to purge the lung with warm property. Therefore, it is important to use pungent herbal medicines for taste invigoration and warm ones for property invigoration. Both pungent and warm herbal medicines, Radix Angelicas Sinensis and Rhizoma Chuanxiong, were combined to invigorate and purge the lung. In addition, Radix Glycyrrhizae are combined as dispatcher herbal medicine, harmonizing all the herbal medicines composing the formula. First, to cure the asthenic syndrome of the liver, the methods of invigorating the liver and the kidney, and purging the lung should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herDal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Bogan-tangon is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.

The objective of this experiment was to investigate the effect of dietary supplementation of herbal medication (HM) on laying performance, blood parameter, and immune response in laying hens. A total of 800 Hy-Line Brown laying hens of 60 weeks of age were randomly allotted to one of four dietary treatments with four replicates per treatment. Three additional diets were prepared by adding 0.5, 1.0 or 1.5 % of HM to the basal diet. Feeding trial lasted 7 weeks under 16L:8D lighting regimen. The diet and water were available ad libitum. Hen-day egg production in groups fed diets with 0.5% and 1.5% HM was significantly (P<0.05) higher than that of control. Feed conversion ratio in group fed diet with 0.5% HM showed the lowest value (P<0.05). Egg weight, feed intake, broken and shell-less egg production were not affected HM supplementation levels. Egg yolk color was significantly greater in all HM supplemented groups than basal treatment. However, eggshell strength, eggshell thickness, eggshell color, and Haugh units were not affected by HM supplementation level. There were no differences in leukocyte counts among the treatments. Plamsa IgM concentration was (P<0.05) higher in all HM treated groups. In conclusion, dietary HM improved egg production, and IgM of laying hens.

This study investigated the anti-diabetic effects of the mixed water extract (JDG 100) composed of Lycii Cortex, Acanthopanax senticosus and Cordyceps militaris on glucose-regulating key enzymes such as glucokinase (GK), acetyl-CoA carboxylase (ACC). In the current study, HepG2 cells were exposed to pathological condition such as hyperglycemic condition (4.5 g glucose/L) with JDG 100 and then experiments such as RT-PCR and Western blotting were carried out. JDG 100 treated cells increased to $168{\pm}0.04%$ and $182.4{\pm}0.03%$ in GK mRNA and protein expressions, respectively, compared to control. Treatment of the JDG 100 up-regulated ACC mRNA ($127.3{\pm}0.02%$) and protein ($126.7{\pm}0.24%$) of HepG2 cells in the high glucose media. These observations suggest that JDG 100 mixed water extract may have a potential as an anti-diabetic agent in type 2 diabetes mellitus.

Objective：Gagam-Gongjin-dan (GGD) is an oriental medicinal prescription composited with Cervi parvum Cornu, Corni Fructus, Angelica Gigantis Radix, Lycii Fructus, Dioscoreae Rhizoma, Citri Pericarpium, Gastrodiae Rihzoma, Agastachis Herba, Cassiae cortex, Scutellariae Radix and Schisandrae Fructus. The purpose of this study was to investigate the effects of GGD extract against acetaminophen (APAP)-induced liver injury in mice. Methods：GGD extract was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. The first, we investigated the antioxidant effects of GGD extract on electronic donating ability (DPPH), nitrite (NO) scavenging and superoxide dismutase (SOD)-like activity. The next, we investigated the possible hepatoprotective effect of GGD extract administration against acetaminophen-induced liver injury in mice. Mice were orally administrated with or without GGD extract of different doses (25-100 mg/kg/day) one times per day for 6 days. After 3 days, APAP was orally applied with a single dose (400 mg/kg). Results：GGD extract increased DPPH, NO and SOD-like activities in dose dependant. APAP treatment significantly increased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities in plasma. Also, APAP treatment significantly evaluated lipid peroxidation product thiobarbituric reacting substances (TBARS) and depleted some antioxidant enzymes (superoxide dismutase, catalase, d-aminolevulinate dehydratase and gluthathione peroxidase activities) in liver homogenates compared to the control group. However, the orally administration of GGD extract was able to counteract these effects. Histological studies provided supportive evidence for biochemical analysis Conclusions：These results suggest that GGD extract has a potential antioxidant and hepatoprotective effect against APAP-induced liver injury, these properties may contribute to liver disease care.
