Functional dyspepsia is one of the most common bowel disorders as prevalent of 7.7% Korean population. The cardinal manifestations include bothersome postprandial fullness, early satiation, epigastric burning or pain. These features are chronic and should be presented recurrently with no other compatible organic disease to explain the symptoms. Even though it is not life-shortening, functional dyspepsia usually make the health-related quality of life worse especially if other functional bowel disorder coexist. The coexistence of functional bowel disorders is called as 'overlap syndrome'. Anxiety, somatization and insomnia is more prevalent in overlap syndrome compared with sole functional bowel disorder. Therefore, it is worthwhile that physician interviews and elucidates whether the dyspeptic patient had other kinds of functional bowel disorders, and manages the underlying psychotic pathology. Placebo effect is large in functional dyspepsia, and there is only four kinds of prokinetics that is proven to be superior to placebo. Adverse events relating prolonged administration of prokinetics sometimes fatal or irreversible, physician willing to describe prokinetics should be familiar to the possible adverse effects and the relating risk factors. Pathologic acid reflux is not uncommon in functional dyspepsia, and acid-suppressant is equivalent to the prokientics in most of dyspeptic patients.

Abstract: This retrospective study delved into the effects and safety considerations associated with the concomitant usage of hypoglycemic agents and herbal extracts, specifically Pyeongwi-san (PWS) or HyangsaPyongwi-san (HSPWS) in the context of type 2 diabetes mellitus management. Methods: The investigation involved 38 inpatients with type 2 diabetes mellitus who received PWS or HSPWS treatment at Kyung Hee University Korean Medical Hospital from January 2012 to December 2022. By investigating clinical attributes and conducting laboratory assessments, this study aimed to discern the impact of these herbal extracts on blood glucose levels, encompassing fasting blood sugar (FBS) and mean 2-hour postprandial glucose (PP2) levels. Furthermore, the safety profile of the herbal extracts was assessed by comparing liver function indicators, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyl transferase (GGT), alongside kidney function markers, such as blood urea nitrogen (BUN) and creatinine (Cr). Results: Following the administration of the herbal extracts, no statistically significant alterations in FBS and mean PP2 levels emerged compared to the baseline levels. Notably, the safety evaluation revealed no significant differences in liver and kidney function parameters following herbal extract administration. Conclusion: The results of this research indicate that using PWS or HSPWS alongside hypoglycemic medications could be a beneficial additional method for addressing digestive symptoms in individuals with type 2 diabetes mellitus. Notably, this combination seems to have no negative interactions with other drugs.

Pyungwi-san(PWS) have been using as a basic prescription of digestive disorder in Korean traditional medicine. This study was performed to examine the in vitro antioxidant activity of the extract using different antioxidant tests including by 1,1-diphenyl-2-picryl-hydrazil (DPPH) radical scavenging, superoxide anion radical scavenging, metal chelating hydrogen peroxide scavenging, lipid peroxydation protective effect and scavenging effect of nitric oxide and peroxynitrite. Herbal-acupuncture solution of PWS(PWS-HS) exhibited a concentration-dependent inhibition of DPPH radical adduct formation and it showed dose-dependent free radical scavenging activity onto superoxide anions. In addition, the result of metal chelating hydrogen peroxide scavenging and ammonium thiocyanate experiments showed that PWS-HS was an active scavenger of hydroxyl radicals. Furthermore, it was also found to be effective in scavenging nitric oxide and peroxynitrite, well-known cytotoxic species that can oxidize several cellular components such as proteins, lipids and DNA.

Objectives : This study was designed to investigate protective effects of Sayeoksanhap-Pyeongweisan-Gamiban(SPG) on hematological changes in rats damaged by CCl4 Methods : We investigated the effects of SPG on hematological changes in terms of AST/ALT levels, Total cholesterol, HDL-cholesterol and triglyceride in serum and lipid peroxidation in rat liver. Results : Administration of SPG decreased AST level in serum effectively. In addition, lipid peroxidation in liver tissue, which was elevated by injection of CCl4, was decreased by administration of SPG. In contrast, ALT level, Total cholesterol, HDL-cholesterol and triglyceride in serum were not affected by administration of SPG. Conclusion : These results suggest that oral administration of SPG was useful to protect liver against CCl4 by its antioxidant action in liver tissues.

Objectives : This study was designed to investigate effects of Sayeoksanhap-Pyeongweisan-Gambang (SPG) on gene expression in rats damaged by CCl4 Methods : We investigated the effects of SPG on gene expression in terms of microarray methods in rat liver which were obtained from rats damaged by CCl4. Results : Decreased gene expressions, which were induced by single injection of CCl4, were restored to those in normal rats by administration of SPG or herbal acupuncture. In acupuncture group, gene expressions were restored by 80% of those in control group. In oral administration group and combination group, gene expressions were restored above 90% of those in cuntrol group. Conclusion : These results suggest that oral administraion of SPG was useful to protect liver against CCl4 by its restoration of gene expressions in liver resected from rat damaged by CCl4.

The effects of gastric acidity on the bioavailability of scopolamine hydrobromide and ${\ell}$-hyoscya-mine were studied in rabbits. Each drug was administered orally at dose of 0.2mg/kg to gastric acidity controlled rabbits. The plasma concentration of scopolamine and ${\ell}$-hyoscyamine were determined by selected ion monitoring in GC/MSCScopolamine; m/Z= 138, ${\ell}$-Hyoscyamine; m/z= 124). Rabbits with hypoacidity showed significantly higher Cp and AVC than rabbits with hyperacidity after oral administration of each drug. From the results of this experiment, it is desirable that dosage regimen of dose of scopolamine and hyoscyamine should be adjusted when the drugs should be administered with antacids in clinical practice.

Using modified technique of Schmidt et al, as described previously (Korean J. Pharmacol 9 : 17, 1973), the stomach of female rats were perfused with physiological saline under urethane anesthesia. The acid-secretory response of the perfused stomach to i.v. hypertonic glucose (50%), casein hydrolysate (20%) or saline (6%) solution were studied with or without histamine or methacholine stimulation. A significant decrease of acid secretion from the rat stomach was induced by i.v. hypertonic glucose or saline solution. The histamine-stimulated acid secretion was also decreased by simultaneous administration of the hypertonic glucose or saline. However, methacholine-stimulated acid response was not affected by the hypertonic glucose. Intravenous infusion of 20% casein hydrolysate solution resulted in an increase in acid output from the stomach under histamine stimuli. These results lead to the conclusion that the inhibitory responses of acid secretion due to i.v. hypertonic glucose solution are brought through the effect of histaminergic, not cholnergic mechanism(s) in the gastric secretion.
