  • In Oriental medicine, the prescriptions composed of several herb medicines have been used. It is still unclear how the sum of several extracts of anti-thirst drugs represents the anti-lipid peroxidative action. Three anti-thirst herb medicines, Kalopanax pictus (K), Pueraria thunbergiana (P) and Rhus verniciflua (R), were extracted with MeOH and $H_2O$, respectively, and the former one was fractionated into the resultant EtOAc extract. Each extract was reconstituted to give KPR311, KPR131 and KPR113 where, for example, KPR311 represents the complex of K-P-R {3:1:1 (w/w/w)} of the three extracts. The order of the inhibitory effect in bromobenzene-induced lipid peroxidation in rats was as follows: EtOAc extract>$H_2O$ extract>MeOH extract. Extract complexes were found to be more potent than the extracts of individual crude drugs. The KPR131 of EtOAc extract was found to be the most potent among the tested samples. These anti-lipid peroxidative effects were also supported by the decrease of aniline hydroxylase activity and aminopyrine N-demethylase activity, on the other hand by the increase of epoxide hydrolase activity. All the tested samples were assayed in vitro antioxidative effects such as DPPH assay, ADP/NADPH/Fe$^{3+}$ assay and ascorbic acid/Fe$^{2+}$ assay. The EtOAc extracts also showed the most significant antioxidative effects. These results suggest that the sum of anti-thirst drugs could reflect the effects of respective crude drugs.s.s.

  • The three crude drugs of the Kalopanax pictus (Araliaceae) roots (K), Pueraria thunbergiana (Leguminosae) flowers (P), and the Rhus verniciflua (Anacardiaceae) heartwood(R) used for anti-thirst drugs in Oriental herb medicine were extracted with MeOH, respectively, and the successive fractionation of the extract gave EtOAc extract. Certain amount ratios of the three extracts were also prepared to compare the antimutagenicity in Ames test. In N-methyl-N(-nitro-N-nitrosoguanidine (MNNG; 0.4 (g/plate)-induced test, the activities of complex mixture were observed between the highest antimutagenic activity of K extract and the lowest P extract. In aflatoxin (AFB$_1$)-induced test, the EtOAc complex (K : P : R=l : 1 : 3) labeled E-113 decreased the revertants of Salmonella typhimurium TA100 by 95%, which activity were highest among other extracts or complexes mixture used. Fractionation of organic solvent mostly increased the antimutagenicity. These trends were also observed in the antimutagenicity test of the mixture of each active component of kalopanaxsaponin A, tectorigenin and sulfuretin. These results supported that many kinds of anti-thirst herb medicine in the prescription could effectively prevent cancer disease.

  • Objectives : To prove the channel-tropism theory in herbology, we investigated the anti-diabetic effect of six herbal plants used for lower wasting-thirst in streptozotocin-induced diabetic rats. Methods : Diabetes was induced in male Sprague-Dawley rats by consecutive injection of streptozotocin (30 mg/kg i.p.) for 5 days. The rats were divided into normal control, diabetic control, and diabetic treatment with Lycii Radicis Cortex (LRC, 300 mg/kg); Corni Fructus (CF, 300 mg/kg); Bombyx Batryticatus (BB, 50 mg/kg); Lycii Fructus (LF, 300 mg/kg); Phellodendri Cortex (PC, 300 mg/kg); Epimedii Herba (EH, 300 mg/kg); and glibenclimide (10 mg/kg) as a reference drug. Herbal extracts or reference drug were administered orally for 28 days. The changes of body weight, food intake and water intake, and serological markers such as blood glucose, serum total cholesterol, triglyceride (TG), blood urea nitrogen (BUN), and creatinine (Cr) were measured. Results : The decrease of body weight and the increase of food and water intake in STZ-induced diabetic rats was improved by the administration of CF and LF. Also, the enhancement of blood glucose and serum total cholesterol, TG, BUN and Cr in STZ-induced diabetic rats was significantly inhibited by the administration of CF, BB, LF and glibenclimide. On the other hand, EH strongly inhibited the increase of BUN and Cr in the sera of STZ-induced diabetic rats. Conclusions : These results suggest that among six herbal medicines used lower emaciation of emaciation-thirst disease, CF, BB, LF and EH show a characteristics including the channel-tropism theory.

  • Objectives : This study was performed to investigate the effect of root extract of Pueraria thunbergiana Bentham (Puerariae Radix, PR) in diabetic mice as similar as emaciation-thirst disease in Oriental medicine. Methods : C57BL/6 mice were fed high fat (HF) and high sucrose (HS) for 8 weeks, and then administrated with 90 mg/kg body weight (bw) of streptozotocin (STZ) for induction of diabetes which is similar to the middle emaciation stage. After 5 days, blood glucose levels were measured, and selected the mice with ranges above $250mg/d{\ell}$. PR water extract was administrated orally once a day for 4 weeks with high fat and high sucrose. The levels of glucose, insulin, total cholesterol, triglyceride, ${\gamma}glutamyl$ transpeptidase (${\gamma}GTP$), glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analysed in the serum. Also, observed their histological changes by hematoxylin and eosin (H&E) of different organs, lung, heart, pancreas, stomach, liver, and kidney. Results : PR extract significantly decreased the levels of serum glucose and insulin in diabetic mice. PR extract significantly increased the levels of triglyceride, total cholesterol, GOT and GPT in diabetic mice. In H&E stain, PR extract inhibited the histopathological changes of lung (as a channel of the upper emaciation stage in the channel-tropism theory), pancreas (as a channel of the middle emaciation stage) and kidney (as a channel of the lower emaciation stage) in diabetic damage. Conclusions : PR extract has an anti-diabetic effect in HF/HS and low-dose STZ-induced diabetic mice. This result suggests that PR follows the channel-tropism theory in the emaciation-thirst disease through the protection of lung, pancreas and kidney.

  • Objective : Phyllostachyos Folium (PF) has been used to treat patients with febrile disease consuming the body fluids marked by fever with restlessness, thirst etc. In the theory of herbology, PF can clear away heat and promote the production of the body fluids, relieve restlessness. Recently PF is known to have anti-bacterial, anti-oxidantic effects. Methods : The present study was carried out to investigate the effects of PF on solid tumor in mice in terms of immune-potentiating and direct cytotoxic action of PF in vitro and vivo study. The present author investigated thymocyte and splenocyte proliferation to confirm immune-potentiating activity of PF and also investigated tumor/body weight ratio and survival rates in tumor bearing mice. Result : In this study, administration of PF decreased tumor/body weight ratio significantly, and prolonged survival duration compared to non-treated control. In addition, treatment with PF suppressed proliferation rate of Sarcoma 180 (S-180) cells significantly, and elevated proliferation rates of thymocytes isolated from normal mice. These results were co-related with in vivo study. Conclusion : In conclusion, these results suggest that PF is useful to treat patient with solid tumor, because PF has direct toxic action for tumor cell and immune -potentiating action for T cells. Further study will need to elucidate exact mechanisms related in anti-cancer action of PF.

  • Objectives : Jigal-san (JGS, 止渴散) has been used in East Asia including Korea, Japan and China for the treatment of breast inflammatory disorders and severe thirst. JGS originated from Euimunpalbeob (醫門八法; Yimenbafa) composed of Lonicerae Flos and Taraxaci Herba. According to previous studies Lonicerae Flos and Taraxaci Herba have an anti-inflammatory effect, respectively. But, there is no studies regarding on the effects of JGS in the immunological activities. The present study evaluated the anti-inflammatory effects of JGS in vitro and in vivo. Methods : Cell viability was evaluated by MTT assay, and NO was evaluated by content of the nitrite content in culture medium. TNF-α, IL-1β and IL-6 were quantified by ELISA. The protein expression of NF-κB, MAPKs, and iNOS were assessed by western blot analysis. Furthermore, the effects of JGS on acute inflammation were observed in rat paw edema model. Results : The JGS ameliorates the LPS-activated changes in the protein expression of NF-κB, p-JNK, and iNOS, as well as the production of NO and pro-inflammatory cytokines. In rat paw edema study, administration of 0.3 and 1.0 g/kg of JGS for 4 consecutive days inhibited the carrageenan (CA)-induced increases of edema and iNOS expression. Conclusions : These results demonstrate that JGS has anti-inflammatory effect in LPS-stimulated RAW 264.7 cells through decreasing the production of inflammatory mediators, via suppression of the NF-κB and MAPK pathways (JNK, not p-38 and ERK). In addition, the results of the CA-induced paw edema indicate that JGS ameliorates an inflammatory edema. Therefore, the present study could provide scientific evidence for the anti-inflammatory effect of JGS as well as the underlying mechanisms.

  • 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.

  • Objective: This study reviewed experimental studies on the effects of Korean medical treatment for diabetes mellitus (DM). Method: We reviewed 24 studies about DM that had been published since 2013. We searched the Korean Institute of Oriental Medicine (KIOM) database with the keyword '당뇨', '消渴', 'Diabetes'. Results: 1. The studies used various Korean medicine treatments; 15 used single medicinal herbs, 6 used herbal complexes, and 2 used acupuncture. 2. The measurement parameters used in the studies included blood glucose, body weight, histochemical change, lipid parameters, and food/water intake. Anti-diabetic effects were demonstrated in most of the studies. 3. The experimental animals used were rats or mice. There were 15 type 1 diabetes models, 7 type 2 diabetes models, and one normal model. Among them, 13 cases of chemical diabetes induced by Streptozotosin (STZ, type 1 diabetes inducer) were the most common. Conclusion: Further articles on Korean medical treatment of DM should be studied.
