Objectives : The purpose of this study was to proofread 'one ryang' in the Decoction of ${\ll}$Treatise on Cold Damage Diseases${\gg}$. Methods : I found out the ratio of maximum dose and minimum dose in this book. On the basis of the ratio, I corrected 'one ryang' in diverse decoctions. Results : In any decoction, maximum dose of medicinal medica in one decoction could not exceed four times minimum dose. Specifically, in the case that maximum dose in one decoction is sixteen ryang, it could not exceed eight times minimum dose in the same decoction. Any medicinal medica used in two decoctions or more, its maximum dose could not exceed four times minimum dose in other decoctions. On the basis of these results, it should be changed into three ryangs that are one ryang dose of 'Haematitum' of Seonbokdaeja Tang, 'Ginger' of Bujageongang Tang, Baektong Tang, Baektonggajeodamjep Tang and Senggangsasim Tang. Furthermore it should be changed into two ryangs that are one ryang dose of 'Coptidis Rhizoma' of Sohamhyung Tang, 'Ginger' of Dowha Tang, 'Ginseng Radix' of Whubaksenggangbanhagamchoinsam Tang, 'Polyporus, Poria Sclerotium, Alismatis Rhizoma, Talcum and Asini Corii Colla' of Jeoryeong Tang, 'Cimicifugae Rhizoma, Atractylodis Rhizoma Alba and Anemarrhenae Rhizoma' of Mahuangshengma Tang and 'Cassiae Cortex Interior' of Gyejigamchoryonggolmoryeo Tang. Conclusions : These results suggest that one ryang of thirteen medicinal medica such as Haematitum or Ginger of eleven decoctions such as Seonbokdaeja Tang or Bujageongang Tang should be changed into two or three ryangs.

The root of Polygala tenuifolia Willd (PT) is known to have neuroprotective effects and as an antidementic herb in Chinese and Japanese traditional medicine. We examined potential neuroprotective effects of PT using the 4-vessel occlusion model in rats. In this study, the efficacy of PT for the prevention of neuronal damage and for the reduction of memory impairment was investigated. The results indicate that PT confers significant neuroprotection especially for ischemic hippocampal neurons.

Antidiabetic effect of Korean red ginseng (RG) processed by puffing in streptozotocin (STZ)-induced diabetic (DM) rats was investigated. Five week-old SD rats were divided into four groups; normal control (NC) group, DM group, red ginseng (RG) group and puffed red ginseng (PG) group. The RG and PG groups were orally provided with RG or PG dissolved in water (500 mg/kg) respectively for seven weeks after single injection of STZ (50 mg/kg, i.v.) followed by identification of DM. NC group received saline vehicle instead of STZ. At the end of feeding of RG or PG, the changes of fasting blood glucose, serum insulin and amylase level and serum lipid profiles were evaluated. Also, oral glucose tolerance test (OGTT), comet assay and histopathological examination were performed. At 7th week, the fasting blood glucose levels of the RG and PG groups were reduced compared to the DM group by 11.54% and 20.22%, respectively. The result of OGTT did not show significant differences among DM and two red ginseng groups. While serum insulin and TG levels were predominantly improved in PG group (p<0.05), serum amylase level was increased in RG group. Alkaline comet assay for checking the oxidative damage of DNA showed that TL (tail length, ${\mu}m$) and TM (tail moment) in the blood lymphocyte of PG group significantly decreased in contrast with DM group. Histopathological results of pancreas showed that destruction of exocrine as well as endocrine might be cured by the administration of RG and PG. These results suggest that PG could exert more protection against STZ-induced toxicity than RG group.

To investigate the protective effect of saponin from red ginseng extract, 2,3,7,8-tetrachlorodibenzo--dioxin (TCDD) was exposed to female guinea pigs and then femur weights was measured. Forty eight female guinea pigs ($820{\pm}25\;g$) were divided into 6 groups. Normal control group (NC) received vehicle and saline; only TCDD-treated group (TT) received TCDD ($5.0\;{\mu}g/kg$, single dose) intraperitoneally; pretreated group of saponin 10 (PE 10) received 10 mg/kg of saponin i.p. for 4 weeks from 1 week before TCDD-exposure; pretreated group of saponin 20 (PE 20) also received 20 mg/kg of saponin i.p. for 4 weeks from 1 week before TCDD-exposure. While, post-treated group of saponin 10 (CE 10) received 10 mg/kg of saponin i.p for 3 weeks after TCDD-exposure. Post-treated group of saponin 20 (CE 20) received 20 mg/kg saponin i.p for 3 weeks after TCDD-exposure. Body weight of TT group was significantly decreased after TCDD-exposure. However, body weight in all saponin-treated groups increased throughout the experimental period, although the increasing rate was slower than that of NC group. Body weights of PE 10 and 20 groups showed more higher increase than those of CE groups during the experimental period. Decrease of femur weights in female guinea pigs by TCDD intoxification was significantly recovered by the saponin treatment. Decrease of $Ca^{2+}$ level of femurs in female guinea pigs exposed TCDD also recovered by the treatment of saponin from red ginseng extract. Especially, PE20 group showed the highest increase of the $Ca^{2+}$ level in femur among the saponin treated groups. These results suggest that ginseng saponin might be a useful protective agent against femur damage caused to decrease of $Ca^{2+}$ by TCDD.

The spontaneous frequency of genetic damage and the possible relationship of this damage to dietary and nutritional variables were investigated in peripheral blood lymphocytes from 45 elderly people using sister chromatid exchange (SCE). The relationship of dietary and nutritional factors on SCE was assessed by different degrees of smoking status such as smokers (n=14), ex-smokers (n=16) and non-smokers (n=15). Significant relationship of the SCE frequency to nutrient intake of the combined subjects (n=45) was found. When cigarette smoking status was taken into account, there were negative linear relationships between SCE and fat, phosphorus or vitamin A intakes of the non-smokers as well as SCE and the dietary quality scores. There was a positive linear relationship between SCE and food frequency of meat and fish among the smokers. Use of artificial sweetners in ex-smokers of the elderly people produced a significant increase of SCE in comparison with the mean SCE for those not using sweetners. Other dietary parameters, including intake of coffee, green tea and ginseng tea, alcohol consumption, use of processed foods, and administration of vitamin pills did not show any correlation with SCE. These results suggested that dietary fat, phosphorus or vitamin A status are the major determinants of spontaneous DNA damage in lymphocytes of the elderly people.

Background: Chronic heavy alcohol consumption may raise the risk of developing type 2 diabetes mellitus. Saponins inhibit apoptosis of pancreatic islet cells and reduce lipid parameters. The present study was designed to investigate the effect of saponin on chronic ethanol-treated diabetic rats. Methods: Long-Evans Tokushima Fatty (LETO) and Otsuka Long-Evans Tokushima Fatty (OLETF) rats were pair-fed a Lieber-DeCarli diet with and without 5% ethanol for 12 wks. Two weeks after starting the pair-feeding with the Lieber-DeCarli diet, intraperitoneal injection of saponin was performed for 10 wks. To perform the experiments, rats were divided as follows: LETO-Control (LC), LETO-Ethanol (LE), LETO-Ethanol-Saponin (LES), OLETF-Control (OC), OLETF-Ethanol (OE), and OLETF-Ethanol-Saponin (OES). Results: The weights of epididymal and mesenteric fat tissue in LES and OES rats were the lightest from among the LETO and OLETF groups, respectively. The secretion of alanine aminotransferase and cholesterol in OES rats decreased significantly compared to their secretion in OC and OE rats, respectively. The islets of the pancreas in LE and OE rats showed clean, unclear, and smaller morphology compared to those of LC, LES, OC, and OES rats. In addition, the expression of insulin in the islets of the pancreas in LC, LES, OC, and OES rats was higher than in LE and OE rats. Conclusion: Saponin may not only be helpful in alleviating the rapid progress of diabetes due to chronic alcohol consumption in diabetic patients, but may also show potential as an antidiabetic drug candidate for diabetic patients who chronically consume alcohol.

The pharmacological properties of ginseng are mainly attributed to ginsenosides, the active constituents that are found in the extracts of different species of ginseng. Lately; the studies on ginsenosides are mainly focused on IH-901, a major intestinal bacterial metabolite of ginsenosides. In this study; we examined the anti-diabetic activity of IH-901 in C57BU61 db/db mice model. IH-901 was administrated orally at a dose of 20 mg/kg for 5 weeks. During the experimental period, body weight and blood glucose levels were measured every week. After 5 weeks, db/db mice were sacrificed and diabetic parameters were analyzed. IH-901 treated group showed a significant decrease in fasting blood glucose levels (from 10.5 mM to 9.4 mM), insulin resistance index (from 163.6 to 100.2) and triglyceride levels (from 115.3 to 70.1) compared to the diabetic control. In Pancreatic islets morphology; IH-901 treated group revealed much less infltrated mononuclear cells, indicating that IH-901 recovered ${\beta}$-cell damage due to hyperglycemia. In addition, IH-901 upregulated expressions of glucose transporter 4 (GLUT4) and PPAR-${\gamma}$ in skeletal muscle and adipose tissue, respectively. Taken together IH-901might be a potential anti-hyperglycemic agent with insulin sensitizing effect.

Background: Ginsenoside Rd is a natural compound with promising neuroprotective effects. However, the underlying mechanisms are still not well-understood. In this study, we explored whether ginsenoside Rd exerts protective effects on cerebral endothelial cells after oxygen-glucose deprivation/reoxygenation (OGD/R) treatment and its potential docking proteins related to the underlying regulations. Method: Commercially available primary human brain microvessel endothelial cells (HBMECs) were used for in vitro OGD/R studies. Cell viability, pyroptosis-associated protein expression and tight junction protein degradation were evaluated. Molecular docking proteins were predicted. Subsequent surface plasmon resonance (SPR) technology was utilized for validation. Flow cytometry was performed to quantify caspase-1 positive and PI positive (caspase-1+/PI+) pyroptotic cells. Results: Ginsenoside Rd treatment attenuated OGD/R-induced damage of blood-brain barrier (BBB) integrity in vitro. It suppressed NLRP3 inflammasome activation (increased expression of NLRP3, cleaved caspase-1, IL-1β and GSDMD-N terminal (NT)) and subsequent cellular pyroptosis (caspase-1+/PI + cells). Ginsenoside Rd interacted with SLC5A1 with a high affinity and reduced OGD/R-induced sodium influx and potassium efflux in HBMECs. Inhibiting SLC5A1 using phlorizin suppressed OGD/R-activated NLRP3 inflammasome and pyroptosis in HBMECs. Conclusion: Ginsenoside Rd protects HBMECs from OGD/R-induced injury partially via binding to SLC5A1, reducing OGD/R-induced sodium influx and potassium efflux, thereby alleviating NLRP3 inflammasome activation and pyroptosis.

For standardization of LMK02 quality, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelica gigas Nakai in the constituents of LMK02 were estimated as indicative components. From LMK02 water extract, has been used in vitro test for its beneficial effects on neuronal survival and neuroprotective functions, particularly in connection with APP-related dementias and Alzheimer's disease (AD). $A{\beta}$ oligomer derived from proteolytic processing of the ${\beta}$-amyloid precursor protein (APP), including the amyloid-${\beta}$ peptide ($A{\beta}$), play a critical role in the pathogenesis of Alzheimer's dementia. We determined that oligomer amyloid-${\beta}$ ($A{\beta}$) have a profound attenuation in the increase in rat hippocampus H19-7 cells from. Experimental evidence indicates that LMK02 protects against neuronal damage from cells, but its cellular and molecular mechanisms remain unknown. Using a hippocampus cell line on $A{\beta}$ oligomer-induced neuronal cytotoxicity, we demonstrated that LMK02 inhibits formation of $A{\beta}$ oligomer, which are the behavior, and possibly causative, feature of AD. In the Red Ginseng, the average amounts of Ginsenoside Rg3 were $47.04{\mu}g/g$ and $42.3{\mu}g/g$, 90 % of its weight were set as a standard value. And, in the Angelica gigas Nakai, the average amounts of Decursin were 2.71 mg/g and 2.44mg/g, 90 % of its weight were also set as a standard value. The attenuated $A{\beta}$ oligomer in the presence of LMK02 was observed in the conditioned medium of this $A{\beta}$ oligomer-induced cells under in vitro. In the cells, LMK02 significantly activated antiapoptosis and decreased the production of ROS. These results suggest that neuronal damage in AD might be due to two factors: a direct $A{\beta}$ oligomer toxicity and multiple cellular and molecular neuroprotective mechanisms, including attenuation of apoptosis and direct inhibition of $A{\beta}$ oligomer, underlie the neuroprotective effects of LMK02 treatment.
