A group of traditional folk medicines obtained from the fruits of Rutaceae plants, such as Ponciri Fructus Immaturus (PFI) from Poncirus trifoliata Raf., Aurantii Fructus Immaturus (AFI) and Aurantii Pericarpium (AP) from Citrus aurantium L., and Aurantii Nobilis Pericarpium (ANP) from Citrus unshiu Marc., has been widely used for improving poor gastrointestinal function in East Asia, including in China and Korea. In the present study, the effects of Rutaceae-fruit-derived folk medicines on gastrointestinal motor function were investigated and compared by measuring in vivo gastric emptying and intestinal transit in mice. Among the aqueous and ethanolic extracts of some Rutaceae-fruit-derived folk medicines, an ethanolic extract of AP (AP-E) significantly accelerated intestinal transit in a dose-dependent manner without affecting gastric emptying. Furthermore, the intestinal transit rate of AP-E was the highest among all extracts examined in this study, including aqueous extracts of PFI, AFI, and ANP, of which the activities of accelerating intestinal transit have been already reported.

Glucose deprivation and hypoxia frequently occur in solid tumor cells, including pancreatic cancer cells. Glucose deprivation activates the unfolded protein response (UPR) and causes the up-regulation of glucose-regulated protein 78 (GRP78). Induction of GRP78 has been shown to protect cancer cells. Therefore, shutting down of GRP78 expression may be a novel strategy in anticancer drug development. Based on this understanding, a screening system established for anticancer agents that exhibit selective cytotoxicity on pancreatic cancer cells under glucose-deprived conditions. To test this hypothesis, the new compounds isolated, pancastatin A (PST-A) and B (PST-B), from Ponciri Fructus. PST-A and B were identified as glabretal triterpenoid moieties by electrospray ionization mass spectrometry and nuclear magnetic resonance spectroscopic methods. PST-A and B suppressed the accumulation of the UPR hallmark gene, GRP78, during glucose deprivation. Furthermore, PST-A and B showed selective cytotoxicity on PANC-1 pancreatic cancer cells under glucose deprivation. Interestingly, PST-A and B had no effect on these cells under normal growth conditions. Our results suggest that PST-A and B act as novel therapeutic agents to induce selective cell death in glucose-deprived pancreatic cancer cells.

Objectives: This study is to review the effect of Korean medicinal herbs on treatment of benign prostatic hyperplasia induced in rat models, as reported in domestic and foreign journals. Methods: Six electronic databases (EMBASE, PubMed, Oasis, RISS, CENTRAL, and Koreankt) were searched with terms including benign prostatic hyperplasia to identify study reports on treatment of benign prostatic hyperplasia impairment with Korean medicinal herbs. After selecting several studies, the analysis focused on items reflected in the diagnosis of benign prostatic hyperplasia, such as prostate weight, thickness of the prostate epithelium, and prostate specific antigen. Results: Six studies were reviewed. Testosterone propionate was used as a benign prostatic hyperplasia induction material in all the included studies. Cinnamomum verum (CV), Cynanchum wilfordii (CW), Ponciri fructus (PF), Quisqualis indica (QI), Acorus gramineus (AG), and Melandrium firmum (MF) had reduced prostate weight statistically significantly. The QI gave a better response than finasteride in terms of reducing epithelium thickness, and the response was statistically significant. The prostate specific antigen level was lower in the group treated with CV than in the control group. Conclusions: CV, CW, PF, QI, AG, and MF had distinct therapeutic effects. However it is difficult to determine which of these is better by comparing them numerically because the observation items evaluated in a rat model of benign prostatic hyperplasia.

Objectives: Poncirus trifoliata Rafinesque has been known to have anti-allergic effects in skin diseases. However, anti-atopic dermatitis effects of P. trifoliata Rafinesque have not been studied yet in skin diseases. The present study evaluated the anti-atopic dermatitis effects of P. trifoliata Rafinesque (PTR) using external treatments on AD. Methods: AD lesions were induced by the repeated application of 2, 4-Dinitrochlorobenzene (DNCB) on the shaved back of BALB/c mice. $100{\mu}{\ell}$ of PTR extracts was applied to the AD lesions for 11 days. Histological assessments, mast cells count and serum levels of IgE were analyzed. The anti-pruritic effects of PTR were examined by the change of scratching frequency and nerve growth factor (NGF) expression. In addition, the anti-inflammatory effects of PTR were examined by the expressions of Th2/Th1 cytokines and pro-inflammatory in dorsal skin. Results: Histopathological findings showed that topical application of PTR decreased the thickness of dermal and epidermal skin compared with the DNCB group. PTR also notably decreased the mast cells count and serum IgE. The scratching behavior of mice and expression of NGF were significantly reduced. In addition, PTR group significantly suppressed the IL-4, IL-6, IFN-${\gamma}$ and TNF-${\alpha}$ cytokines compared to the DNCB group. Conclusions: These results indicated that P. trifoliata Rafinesque possess anti-pruritus and anti-atopic dermatitis properties. Therefore, P. trifoliata Rafinesque might be used for treatment of pruritus and atopic dermatitis.

This study was performed to investigate concept, systoms, causes of disease, pathogenic mechanisms, therapies and precriptions about senile constipation through the successive medical literature, recent chinese medical literature and chinese medical joumals. Senile constipation seems to be applicable to dryness syndrom and constipation of insufficiency type, have something to do with kidney(the most), lung, spleen and large intestine. The most principal cause of disease is yin-fluid, the rest deficiency of qi, insufficiency of yang, stagnation of qi and retention of fever etc. There are enriching the blood and moistening dryness in principal therapy, the rest are invigorating qi and loosing the bowel, warming and invigorating the spleen and kidney, regulating the flow of qi and promoting the stagnancy of qi and expelling the pathogenic heat etc. In prescriptions there are Yunjangtang, Jengaektang, Hwanggitang, Jechunjeon, Yukmatang and Majainhwan as the causes of disease, meanwhile are Yungjang-tang, Jechunjeon and Majainhwan in the vulgaris prescriptions. And in medical herbs there are nourishing yin medicines as Rhizoma rehmanniac, Radix ophiopogonis and Radix scrophulariae etc., invigorating qi medicines as Radix astragali, Radix codonopsitis and Radix polygoni multiflori etc, invigorating yang medicines as Caulis cistanchis and Semen psoraleae etc., promoting qi circulating medicines as Radix saussurea, Lignum aquilariae and Radix linderae etc., and reducing fever and therapeutic method to keep the adverse qi flowing downward medicines as Semen cannabis, Rhizoma rhei, Fructus immaturus ponciri, and Cortex magnoliae etc.. Meantime Rhizoma rehmanniae, Radix ophiopogonis, Caulis cistanchis, Radix angelicae gigantis, Semen cannabis, Semen biotae, Semen pruni japonicae and Semen persicae in principal herb-medicines. In clinical reports the process of disease was between 10 to 20 years, the evacuation cycle between 4 to 7 days, generally possessed chronic diseases as hypertension, diabetes, arteriosclerosis and cerebro- vascular disorders etc. and the efficiency rate was more than 90%. The senile constipation is occured in succession or promoted by chronic diseases as obesity, hypertension, diabetes, arteriosclerosis. hrperlipemia, cerebro- vascular disorders etc., so diet-regulating, adequate exercise, proper evacuation-habit and psychologic rest etc. are important more than medicine-treatments.

Jeechool-Whan (JW) is a prescription of Ponciri Fructus Immaturus and Atractylodis Rhizoma Alba and improves the functions of the stomach and the spleen. Although it is said in Korean Medicine that the spleen and the stomach are the roots of the body's resistance, the meaning of 'improving the spleen and the stomach' is very comprehensive. Moreover, there are lots of drugs that are said to improve the spleen and the stomach, and the number of prescriptions using these drugs is huge. In this study, we focused on the new effect and mechanism of the JW on the ovalbumin (OVA)-induced allergic rhinitis (AR) model. The increased number of rubs and the increased levels of IgE and histamine in the OVA-sensitized mice were inhibited by JW administration. The balance of Th1/Th2 cytokine level was regulated by JW administration. The levels inflammatory proteins were decreased by JW administration in the nasal mucosa of the OVA-sensitized mice. Eosinophils and mast cells infiltration increased by OVA-sensitization was also decreased in the JW-administered mice. In addition, JW inhibited caspase-1 activity in the same nasal mucosa tissue. In activated human mast cells, JW inhibited the receptor interacting protein-2, I${\kappa}$B kinase-${\beta}$, nuclear factor-${\kappa}$B/Rel A, and caspase-1 activation. In conclusion, this study will be support the clear understanding of the concept of the spleen and the stomach in traditional Korean medicine as well as for a possibility of finding a cure for this AR in traditional medical treatments.
