Background: Korean Red Ginseng has been widely used in traditional oriental medicine for a prolonged period, and its pharmacological effects have been extensively investigated. In addition, Angelica gigas and deer antlers were also used as a tonic medicine with Korean Red Ginseng as the oriental herbal therapy. Methods: This study was conducted to evaluate the potential toxicological effect of KGC-HJ3, Korean Red Ginseng with angelica gigas and deer antlers, on reproductive and developmental functions including fertility, early embryonic development, maternal function, and embryo-fetal development. KGC-HJ3 was administered by oral gavage to Sprague-Dawley rats (22 animals per sex per group) at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on fertility and early embryonic development. In addition, KGC-HJ3 was also administered by oral gavage to mating-proven Sprague-Dawley rats (22 females per group) during the major organogenesis period at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on maternal function and embryo-fetal development. Results and conclusion: No test item-related changes in parameters for fertility, early embryonic development, maternal function, and embryo-fetal development were observed during the study period. On the basis of these results, it was concluded that KGC-HJ3 did not have toxicological potential on developmental and reproductive functions. Therefore, no observed adverse effect levels of KGC-HJ3 for fertility, early embryonic development, maternal function, and embryo-fetal development is considered to be at least 2000 mg/kg/day.

약물이나 허브 제품으로 인한 간세포 손상은 이러한 화합물을 만성적으로 투여할 때 일어날 수 있는 중요한 문제 중 하나이다. 따라서 여러 가지의 치료 과정 중 간세포 생존율을 향상시키는 것은, 약물 적용에 있어 광범위한 기회를 제공할 수 있다. Valproic acid (VPA)는 자연적으로 발생하는 발레르산에서 파생된 분지형 단사슬 지방산으로 뇌전증과 발작을 치료하는 데 일반적으로 사용된다. 뿐만 아니라 VPA는 암, HIV 치료, 신경 퇴행성 질환에 수많은 효과를 발휘하지만, 간에 대한 VPA의 잠재적인 영향과 그 작용 메커니즘은 완전히 설명되지 않았다. 여기서, 우리는 VPA의 처리가 쥐 간세포(Hepa1c1c7)에서 PPAR 알파(PPAR-α)와 섬유아세포 성장 인자 21(FGF21)의 전사 수준을 증가시킨다는 것을 입증했다. VPA에 의해 유도된 FGF21 발현은 PPAR-α 결손 조건에서 상당히 억제되었다. 후속 실험에서 FGF21 신호 경로가 FGF 수용체 억제제에 의해 차단되었을 때, 간세포 생존력이 크게 억제되었음을 보여주었다. 마지막으로, 우리는 AMPK 인산화가 VPA에 의해 유도된 PPAR-α 증가에 작용하지 않는다는 것을 추가로 확인했다. 이러한 결과는 FGF21 발현의 증가가 VPA에 의해 유도된 간 독성을 완화시킬 수 있다는 것을 제시하며, 이와 같은 결과는 FGF21의 증감 여부가 VPA 치료 중 나타날 수 있는 간 손상을 예측하는 잠재적인 바이오마커로 사용될 수 있음을 제시한다.

In vitro cytotoxic activities of cisplatin combined with Chungpesagan-tang or puerarin, which were treated with or without human intestinal bacteria, were measured. When cisplatin was combined with Chungpesagan-tang and its ingredient treated without intestinal bacteria, they did not affect the in vitro cytotoxicity of cisplatin against tumor cell lines. However, when cisplatin was combined with intestinal bacteria-treated Chungpesagan-tang and its ingredients, the cytotoxicities against SNU C4, L1210, A549 and P388 tumor cell lines were synergistically increased. Puerarin, which was isolated from Puerariae Radix, did not show in vitro cytotoxicity. However, its metabolite, daidzein, showed potent cytotoxicity against tumor cell lines and was synergistic by the combined usage of cisplatin. These results suggest that natural glycosides are not only prodrugs which can be transformed to active compounds by intestinal microflora, but the combined usage of cisplatin with natural components, such as daidzein, and herbal medicinal polyprescriptions, such as Chungpesagan-tang, may be a new method for prevention and minimization of the toxicity of cisplatin.

Alzheimer's disease (AD), one of the most common forms of dementia, is characterized pathologically by the presence of intracellular neurofibrillary tangles and deposition of ${\beta}$-amyloid ($A{\beta}$) peptides of 40-42 residues, which are generated by processing of amyloid precursor protein (APP). $A{\beta}$ has been believed to be neurotoxic and now is also considered to have a role on the mechanism of memory dysfunction. Here, we show that MeOH extract from stem bark of Platycarya strobilacea Sieb. et. Zucc. (PSM) affects on the processing of APP from the APPswe over-expressing Neuro2a cell line. We found that PSM may regulate the processing of APP and increase the sAPP${\alpha}$. PSM does not change the protein level of presenilin and nicastrin, however, it reduces the protein expression level of BACE1. In addition, PSM reduces the secretion level of $A{\beta}42$ and $A{\beta}40$ from the cell line without toxicity. We suggest that Platycarya strobilacea may be useful as a herbal medicine to treat Alzheimer's disease.

Glehnia littoralis (Umbelliferae), a perennial herb distributed along the coastline of northern Pacific countries, is the medicinal plant used traditionally for treatment of various diseases. This review focuses on the various pharmacological activities of Glehnia littoralis for understanding about its traditional medicinal applications, medicinal uses in the modern society, and potentials for drug development Glehnia littoralis was reported to have anti-oxidant, anti-tumor, anti-amnesic, blood circulation-promoting, immunomodulatory, anti-microbial, and allelopathic activities. However, their mechanisms remain to be clarified. Because Glehnia littoralis has been prescribed in traditional Oriental medicine as a tonic herb, Glehnia littoralis can be better than other chemical drugs and medicines which exert the equal pharmacological activities. Although the activities of Glehnia littoralis are not specifically high-potent with unique mode of action, it may turn out that it can be beneficial to exert multiple pharmacological activities. In view of low toxicity, relative cheapness, presence in the diet, and occurrence in various herbal remedies of Glehnia littoralis, it needs to be prudent to evaluate its properties and applications further.

The root of Pseudostellaria heterophylla Pax et Hoffm. (Caryophyllaceae) is a herbal medicine called Taejasam(太子蔘) and used as a good tonic in China that strengthens the functions of the lung and the stomach like Ginseng in Korea. It has been known to have the antitussive activity for tuberculosis, appetizing effect and antifatigue activity, and so on. Especially it has been known to generate body fluids for the severe thirst and the shortage of water in body after a febrile disease for a long time. Recently some components of cyclic peptides, pseudostellarins A,B,C,D,E,F,G, that inhibit the activity of tyrosinase, were separated from this root. In this report several biological activities including acute toxicity, analgesic activity, antifatigue activity, bile juice increasing activity, hepatoprotective activity and antiinflammatory activity were investigated. These results showed as such; $LD_{50}$ of methanol extracts was above 10,000 mg/kg. The analgesic effect was revealed in the writhing test using rats. The BuOH fractions showed a prominent antifatigue effect against immobilized stress, significant hepatoprotective activities against $CCl_4$ intoxication and inhibitory effect on carrageenin-induced edema in rat's paw.

Cancer is a leading cause of death worldwide. Due to the toxic side effects of the commonly used chemotherapeutic drug cyclophosphamide (CTX), the use of herbal medicines with fewer side effects but having potential use as inducing anti-cancer outcomes in situ has become increasingly popular. The present study sought to investigate the effects of a methanolic extract of Bauhinia tomentosa against Dalton's ascites lymphoma (DAL) induced ascites as well as solid tumors in BALB/c mice. Specifically, B. tomentosa extract was administered intraperitonealy (IP) at 10 mg/kg. BW body weight starting just after tumor cell implantation and thereafter for 10 consecutive days. In the ascites tumor model hosts, administration of extract resulted in a 52% increase in the life span. In solid tumor models, co-administration of extract and CTX significantly reduced tumor volume (relative to in untreated hosts) by 73% compared to just by 52% when the extract alone was provided. Co-administration of the extract also mitigated CTX-induced toxicity, including decreases in WBC count, and in bone marrow cellularity and ${\alpha}$-esterase activity. Extract treatment also attenuated any increases in serum levels of $TNF{\alpha}$, iNOS, IL-$1{\beta}$, IL-6, GM-CSF, and VEGF seen in tumor-bearing hosts. This study confirmed that, the potent antitumor activity of B.tomentosa extract may be associated with immune modulatory effects by regulating anti-oxidants and cytokine levels.

Matricaria Chammomillal L., Foemiculum Vulgare mill, and Plantago Psylium L. have been screened for their hepato protective activities against liver damge induced by $CCl_4$ intoxication in mice. Hydroalcoholic extractions (2:8) of herbal drugs were concentrated in vacuo and concentrated crude extracts of Matrica Chammomilla L. and Foeniculum Vulgare mill were orally administered at doses of 100 mg/kg, 200 mg/kg, 400 mg/kg, and 800 mg/kg. Plantago Psyllium was given at doses of 50 mg/kg, 100 mg/kg, 200 mg/kg, and 400 mg/kg. Liver protective activities of these herbs were determined after administration of $CCl_4$ Liver size, serum enzyme activities, sleeping time, and histopatology of the liver were examined one hour after administration of $CCl_4$. ALT and AST activities, liver weight and sleeping time decreased in groups that received 400 mg/kg of Matricaria Chammomilla L. or Foeniculum Vulgare. Histological investigation showed significant increase in hepatic cell regeneration and reduction in liver injury. The group that received 100 mg/kg Plantago Psylium showed liver protection but protection was not significant in other doses.

Recently a case of liver injury from ingestion of Taeyeumjowi-tang containing Ma-huang(Ephedra sinica stapf) arose. The patient, a 30 year-old woman, was diagnosed with asthenia and anorexia after 6 weeks of ingesting Taeyeumjowi-tang containing Ma-huang(Ephedra sinica stapf) as a treatment for her obesity. Tests showed elevated levels of serum transaminase(ALT 903 IU/L, AST 716 IU/L), alkaline phosphatase (229 IU/L), total bilirubin (1.4 mg/dl). Other possible causes of liver injury were excluded by laboratory test and medical history, so the liver injury was taken to be drug-induced. Saenggangeonbi-tang was administered. After 2 weeks of treatment with this medication, the clinical symptoms and liver function improved. This case is reported with a call for further accumulation of objective data on drug-induced liver injury, and to bring more attention to the relative levels of safety and toxicity of herbal medicines.
