  • Several isoquinoline alkaloids (1 - 18), which have basic chemical structures as protoberberine and aporphine skeletones, were evaluated for their inhibitory activities on AChE and BuChE. Among them, compounds 3, 4, 6, 8 and 12 showed the potent AchE activity with the $IC_{50}$ values ranging from $10.2{\pm}0.5\;{\mu}M$ to $24.5{\pm}1.6\;{\mu}M$, meanwhile, compound 14 - 17 exhibited strong inhibitory activity with $IC_{50}$ values from $2.1{\pm}0.2$ to $5.5{\pm}0.3\;{\mu}M$. Compounds 14 - 17 exhibited selective inhibition for AChE compared with BuChE. The isoquinoline alkaloid possesses aromatic methylenedioxy groups and quaternary nitrogen atoms are crucial for the anti-cholinesterase inhibitory activity.

  • Protective effect of Corydalis ternata against the carbon tetrachloride-induced toxicity was investigated. Carbon tetrachloride($CCl_4$) induces hepatotoxicity due to the reactive free radical(CCl$_3$ . ) generated by cytochrome P-450 enzyme. We examined effects of hexane, chloroform, butanol and water fractions prepared from the Corydalis ternata methanol extract. Rats were treated with those for 3 days, and liver microsomes and cytosols were prepared at 24 hour after last treatment. Hepatoprotective activity of the water fraction was higher than that of other fractions. To examine mechanism of the hepatoprotective effect of Corydalis ternuta, we measured contents of malondialdehyde(MDA), cytochrome P46O(CYP), glutathione, calcium as well as the activities of NADPH-CYP reductase, glutathione S-transferase(GST), superoxide dismutase(SOD), glutathione peroxidase(GPX) and catalase. The fraction inhibited production of MDA, content of CYP and calcium in liver of water fractions - treated rats as compared with those of CCl4-treated rats. The GST activity was increased. We speculate that the O2 radical scavenging activities of the water fraction might play a key role in the mechanism opposing the progression of $CCl_4$-induced hepatotoxicity, but the activities of SOD, GPX, CAT were decreased. These results suggest that the mechanism might be mainly due to the decrease of CYP contents, act as calcium channel blocker and increase of GST activity rather than $O_2$ radical scavenging activities.

  • As many crude drugs are used in the oriental medical field problems on the side effects of these drugs come to the front. To conduct delayed-type hypersensitivity we selected 29 kinds of drugs used frequently for therapeutic agents in oriental medical hospitals (Table I). The cell-mediated immune response was evaluated by measuring the foot pad swelling reaction and humoral immune response by measuring the antibody formation to these crude drugs. Mice were given these drugs intraperioneally for sensitization and challenged with same drug as used for sensitization respectively by intral dermal injection on the left and righ hind foot pad 4 days after senstization and then the foot pads were measured with the dial micrometer. The results were as follow; 1) Gentianae Scabrae Radix, Arecae Semen, Corydalis Tuber, and Paeoniae Radix were significant as delayed-type hypersensitivity inducers. 2) None of the crude drugs tested had effect on the induction of humoral immune response.

  • Motilitone$^{(R)}$ (DA-9701) is a new herbal drug that was launched for the treatment of functional dyspepsia in December 2011 in Korea. The heterogeneous symptom pattern and multiple causes of functional dyspepsia have resulted in multiple drug target strategies for its treatment. DA-9701, a compound consisting of a combination of Corydalis Tuber and Pharbitidis Semen, has being developed for treatment of functional dyspepsia. It has multiple mechanisms of action such as fundus relaxation, visceral analgesia, and prokinetic effects. Furthermore, it was found to significantly enhance meal-induced gastric accommodation and increase gastric compliance in dogs. DA-9701 also showed an analgesic effect in rats with colorectal distension induced visceral hypersensitivity and an antinociceptive effect in beagle dogs with gastric distension-induced nociception. The pharmacological effects of DA-9701 also include conventional effects, such as enhanced gastric emptying and gastrointestinal transit. The safety profile of DA-9701 is also preferable to that of other treatments.

  • The consumption of herbal medicines has been increasing with growing interest in health. However, due to recent climate change and the complex distribution process of herbal medicines with high import dependence the likelihood of contamination with mycotoxin has been increased. Mycotoxins are emerging as key indicators for ensuring safety of herbal medicines. A total of 498 herbal medicine samples were screened for mycotoxin contamination in this study. Aflatoxin in the herbal medicine samples was extracted by using immunoaffinity column, then the extracted aflatoxin was quantified via high performance liquid chromatography coupled with fluorescence detection (HPLC-FLD) method. The extraction method was verified by linearity, recovery, LOD and LOQ. Aflatoxins were detected in 39/498 samples in an average of $7.670{\mu}g/kg$ ($0.610-77.452{\mu}g/kg$ range). Although safety standards for Corydalis Tuber is not currently available in korea, five of the 39 samples had high concentration of aflatoxins (average of $14.9{\pm}4.1{\mu}g/kg$). In conclusion, it is urgent to establish safety criteria of aflatoxin in Corydalis Tuber. The results of the current study suggest that continuous monitoring is necessary for proactive management of herbal medicine safety.

  • Backgrounds: Sticking warm and hot herbs to acupoint in Dog-Days where the strongest Yangqi takes place, Acupoint sticking in Dog-Days is one of Oriental medical treatment to cure winter diseases in the summer. This treatment is widespread in China and Taiwan, and is becoming popular in South Korea nowadays. Objectives: The research has been conducted to evaluate the influencial factors and efficacy in Acupoint sticking in Dog-Days. Methods: We visited one kindergarten in Dog-Days of 2010, and attached pills which are made of Sinapis Semen(白芥子), Corydalis Tuber(玄胡索), Asari Herba Cum Radix(細辛), Juice of Zingiber Officinale(薑汁) to BL-13(肺兪), BL-15(心兪), BL-17(膈兪) of 56 children for 4-6 hours(34 boys, 22 girls, $52.64{\pm}16.85$ months, 19-78 months). Exacerbating effect or non-significant changes in respiratory symptoms before and after the treatment were ified.. The influentialfactors of efficacy were analyzed by Pearson's $x^2$-test and Fisher's exact test. In addition, the efficacy and satisfaction among once, twice, and three times treatment groups were verified by ANOVA. Results: 27 children (48.2%) were effective, but efficacy felt by parents is 45 cases (80.4%). Sex, perspiration, stool, urine, sleep, cold of hands and feet, cold sensitivity, and frequency of Acupoint sticking in Dog-Days has no relation to efficacy(p>0.05). However, the efficacy is poor in 1 and 2 age(p=0.030). Difference among efficacy of once, twice, and three times treatment groups is not significant(p=0.069), whereas there are linear association in frequency of Acupoint sticking in Dog-Days and efficacy(p=0.030). 36 parents (64.3%) are satisfied with Acupoint sticking in Dog-Days, and we observed significant difference among once, twice, three times treatment groups(p=0.041). 19 parents (33.9%) had been known about Acupoint sticking in Dog-Days, but 53 parents (94.6%) wanted repetition, and 41 parents (73.2%) intended to recommend it to acquaintance. Side effects are minor itching in two cases. Twenty seven participants showed positive effect, and forty five people (80.4%) felt beneficial. Sex, perspiration, stool, urine, sleep, cold hands and feet, sensitivity in cold, and frequency of Acupoint sticking in Dog-Days has no relation to the efficacy(p>0.05). Though the efficacy was poor in one and two year old infants, it was linearly correlated with the frequency count and responses from the treatment (p=0.030). Thirty six participants (64.3%) satisfied with the treatment, and so did the first, second, and third participant groups (p=0.041). Even though, only nineteen participants (33.9%) were familiar with Acupoint sticking in Dog-Days, fifty three participants (94.6%) preferred to repeat the treatment, and 41 parents were preferable to recommend the treatment to others. Side effects of minor itching has been reported in a couple cases. Conclusions: Acupoint sticking in Dog-Days is effective in children older than three year old. The effect would be greater when going through the treatment three times. Based on significant satisfaction, intention of repetition and recommendation, strong promotion on Dog-Days are needed to make a better use of Acupoint sticking in Dog-Days for the effective treatment.
