The traditional Asian medicinal herb, roots of Astragalus (A.) membranaceus (Leguminosae), is used for many purposes, some of which are purported to stimulate the release of growth hormone in vivo. Extracts of A. membranaceus were tested to determine whether they stimulate the release of growth hormone in rat pituitary cell culture. A. membranaceus was extracted sequentially with 80% ethanol (fraction A), n-hexane (fraction B); the test compound from the herbal extraction was isolated using silica gel column chromatography and was identified with spectral data. Test compound was also extracted by traditional boiling water methods. Induction of growth hormone in pituitary cell culture was conducted with isolated compounds and extracted fractions of A. Radix (dried roots of A. membranaceus). The fraction A was not active in the rat pituitary cell culture, but the fraction B derived from the ethanol fraction stimulated the release of growth hormone in culture. Six compounds from fraction B (1-6) were isolated and identified previously. The compounds 1,2-benzendicarboxylic acid diisononylester (1), $\beta$-sitosterol (2), and 3-Ο-$\beta$-D-galactopyranosyl-$\beta$-sitosterol (5) did not induce growth hormone release in the culture. Formononetin (3), 9Z, 12Z-octadecadienoic acid (4), stigmast-4-en-6$\beta$-o1-3-one (6) and 98-E, a mixture of 1'-9, 12-octadecadienoic acid (Z,Z)-2',3'-dihydroxy-propylester (7) and 1'-hexadecanoic acid-2',3'-dihydroxy-propylester (8) stimulated the release of growth hormone in the rat pituitary cell culture significantly compared to the control. In conclusions, four compounds isolated from extracts of A. Radix induced growth hormone release in the rat pituitary cell culture. The 98-E isolate was the most active inducer of growth hormone release.

From January 2014 to December 2016, 38 out of 153 inpatients admitted to the Korean Medicine Hospital for more than one month underwent follow-up blood tests to evaluate their liver function levels, and one drug-induced liver injury (DILI) patient was observed. 1. At the time of admission, six (15.8%) of the 38 patients had abnormal alanine aminotransferase (ALT) levels and five of them recovered after hospitalization. 2. At follow-up, two (5.3%) patients had a Council for International Organizations of Medical Science (CIOMS)-based liver injury. One was identified as a liver injury accompanied by pneumonia, and one was judged as a liver injury caused by the drug. 3. The patient had a suspected DILI and completely recovered after 13 days while discontinuing the herbal medication and by using Sanggangunbi-tang (生肝健脾湯).

In the present study we evaluated comparative herb-drug interaction potential of red ginseng total powder, ginsenoside Rg1, and Rb1 by inhibition of CYP isoforms including CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and CYP3A4 using pooled human liver microsomes (HLMs). As measured by liquid chromatography-electrospray ionization tandem mass spectrometry, red ginseng total powder inhibited significantly activities of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and testosterone 6-beta hydroxylation by CYP3A4, but the $IC_{50}$ values were higher than $556{\mu}g/ml$. Activities of CYP2B6, CYP2C9, CYP2D6 and CYP3A4 were inhibited by ginsenoside Rb1. Also, activities of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6 and testosterone 6-beta hydroxylation by CYP3A4 were inhibited by ginsenoside Rg1. The $IC_{50}$ values of ginsenoside Rb1 and Rg1 were higher than $200{\mu}g/ml$. Based on $IC_{50}$ values against CYP isoforms, ginsenosides-drug interactions by CYP inhibition may be very low in clinical situations.

Objective : Many patients take antihypertensive drugs as well as herbal medicines at the same time in order to treat other symptoms or to keep their well-being. In this study, interactions between herbal medicines and synthetic antihypertensive drugs were analyzed. Methods : To investigate the interaction between herbal medicines and synthetic antihypertensive drugs, three electronic databases, including OASIS, Mediline and Sciencedirect were searched. Experimental and clinical studies on the interaction between herbal medicines and antihypertensive drugs were independently reviewed and included. Results : Analyzing selected studies, twenty herbs were found to interact with antihypertensive drugs. Herbs found to increase the antihypertensive effect were Panax ginseng, Carthamus tinctorius, Magnolia officinalis, Silybum marianum, Scutellaria baicalensis, Schisandra chinensis, Sophora flavescens, Piper nigrum, Curcuma longa, Ginkgo biloba, Juncus effuses and Hydrastis canadensis. In contrast, Commiphora myrrha, Rhodiola rosea, Hypericum perforatum, Eurycoma longifolia, and Daturae metel were found to inhibit the antihypertensive effect. Stephania tetrandra could increase or decrease the effect depending on the type of antihypertensive drug. Epedria sínica was suspected of pharmacodynamic interaction with antihypertensive drug. Glycyrrhiza uralensis has been reported to have serious side effects in combination with antihypertensive drugs. Conclusion : These results imply that when used in combination with herbal medicines and synthetic antihypertensive drugs, proper doses and herbs which are to avoid need to be informed to the patients. Despite concerns about interactions between herbal medicines and synthetic drugs, related research is very limited. More systematic researches are needed to give information on patient safety as well as to guide clinical practice.

Tardive Dyskinesia(TD) may be defined as a syndrome consisting of abnormal, stereotyped involuntary movements, which occurs relatively late in the course of drug treatment and in the etiology of which the drug treatment is a necessary factor like schizophrenia, The frequently involved parts of the body in the schizophrenic patients who have TD were tongue, upper extremity, lips and perioral area, jaws, lower extremity, muscle of facial expression, trunk respectively. The last few years have seen a number of well-conducted clinical, biochemical, neuropathological, and therapeutic studies in patients with TD, but there is no satisfactory treatment for the majority of patients with TD. I used herb medicines and some acupoints like GV20(百會), Extra-point(鎭靜), Extra-point(間谷), Liv20(行間), of the chennel of Gall bladder to treated 2 schizophrenic patients with TD from December 2003 to May 2004. The patients with TD were somewhat improved. Nonetheless for just 2 cases, I might thought that this acupuncture therapy could be helpful to treat schizophrenic patients with TD.However, further studies should be followed.

In order to product the saikosaponin which is one of the secondary product from Bupleurum falcatum efficiently through the tissue culture, several levels of agar and gellan gum as the gelling agent, 2,4-D as the growth regulator, and L-phenylalanine as the precursor were used with single or combination treatment on MS basal medium. Gellan gum was more effective than agar as the gelling agent in fresh and dry weight increase of callus induced from Bupleurum falcatum leaf segment. Gellan gum medium supplemented with L-phenylalanine produced 1.6 times of fresh weight more than that of agar. The fresh weight was remarkably high in gellan gum when the calli was treated with the combination of 2,4-D and L-phenylalanine similar to the single treatment of 2,4-D or L-phenylalanine. However, the saikosaponin content in callus was high in gellan gum with the single treatment of L-phenylalanine. Especially, the saikosaponin content in gellan gum supplemented with 1.0mg/L L-phenylalanine was 2 times(2.4 mg/g) higher than that in agar medium supplemented with 0.1 mg/L 2,4-D(0.9 mg/g).

Sayuksan has been widely applied to treat a variety of diseases such as acute hepatitis, gastritis, and colitis. Sayuksan consists of medicinal herbs such as Glycrrhizae uralensis Fischer, Paeonia lactiflora Pallas, Bupleurum falcatum Linne, and Poncirus trifoliata Rafinesqul. Methanol extracts (1 mg/mL) from the four kinds of medicinal herbs did not show antibiotic activities against general test strains and multi-drug resistant strains. The antibacterial activity of fermented medicinal herbs extracts with Lactobacillus spp. strain was confirmed as Gram-positive bacteria which are higher than Gram-negative bacteria. Extracts of Glycrrhizae uralensis Fischer fermented with Lb. casei KCTC 3109 displayed inhibitory diameters of 16 mm against Pseudomonas aeruginosa P01828. Superoxide dismutase (SOD)-like activity of the medicinal herb extracts was not determined, but the extract of Paeonia lactiflora Pallas fermented with six strains of Lactobacillus spp. had the highest antioxidant activity. SOD-like activity of Paeonia lactiflora Pallas extracts fermented by Lb. brevis KCTC 3498 was $41.4{\pm}0.8%$, which was the highest antioxidant activity among the fermented extracts with the other medicinal herbs.

Objectives: The all anti-obesity drugs currently approved by the US Food and Drug Administration work by reducing energy intake. In fact, no approved drug targets energy expenditure. In Korean medicine, it is known to Qi or Yang invigorating therapy could increase energy metabolism. Aconitum carmichaeli Debx (ACD) is a Yang invigorating herb, often used for treat obesity in Korean medicine. In the present study, the authors investigated the regulatory effects of ACD in energy metabolism and mitochondrial biogenesis in C2C12 skeletal muscle cells. Methods: The water extract of ACD (0.2, 0.5 and 1.0 mg/ml) were treated in differentiated C2C12 cells. The protein or mRNA levels of target genes were analyzed and mitochondrial mass were investigated. Results: ACD activated the expressions of peroxisome proliferator-activated receptor gamma coactivator 1-alpha ($PGC-1{\alpha}$), nuclear respiratory factor 1 and TFAM and increased mitochondrial mass. ACD also increased adenosin monophosphate-activated protein kinase (AMPK), and acetyl-CoA carboxylase. Conclusions: This study suggests that ACD has the potential to increase energy metabolism and mitochondrial biogenesis by activating AMPK and $PGC1{\alpha}$.

Psoralen(7H-Furo［3.2-g］ ［1］benzopyran-7-one) and angelicin(2-Oxo-[2H]- furo[2.3-h]-1-benzopyran) are angular furocoumarin with diverse photobiological effects. They are major components of Psoralea corylifolia L.(破古紙). Psoralea corylifolia L. is used for a tonic and nursing one's energy. It can be also used for loss of virility. vitiligo. a skin disease, etc.. But a well known and often appreciated side effects f psoralens is the hyperpigmentation caused by this treatment. A women who used the herbal drug-mixed-medicine named'sobaeksu' to treat her vitiligo made a complaint against the orinetal medical doctor. She complained that her skin got burned to 2nd degree by the liquid. 'sobaeksu' through a medical celtficate. So we analyzed the components of that liquid with gas chromatography and gas chromatography/mass spectometry. It has 57.3% ethyl alcohol and two kinds of psoralens. Psoralens were psoralen and angelicin and each one of their contained quantity was 0.128mg/ml and 0.123mg/ml.
