In order to study the immunohistochemical effects of Opae-san on gastric ulcer induced by HCl-aspirin in rats, experiments were done by oral administration and measure histological features of ulcer lesion, scaning electron microscopic appearance, the changes of numbers of parietal cells, chief cells, gastrin and somatostatin-immunoreactive cells. The obtained results are as follows: 1. Ulcerative lesions were numerously detected in control groups especially in junction of cardiac-fundic gastric mucosa and histologically very severe injury to gastric epithelium were observed too but in the Opae-san administrated groups, no gross lesion of ulcer were detected and histologically minor injury of gastric mucosa were observed. Most slight injuries to gastric mucosa were observed in 5 days after treatment. 2. The numbers of parietal cells were remarkably increased in control group but in Opae-san administrated groups appeared significant decrease compared to control groups. Most remarkably decrease of the numbers of parietal cells compared to control groups were observed in 5 days after treatment. 3. The numbers of chief cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably increase of the numbers of chief cells compared to control groups were observed in 5 days after treatment. 4. The numbers of gastrin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of gastrin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 5. The numbers of somatostatin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of somatostatin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 6. Scaning electron microscopically, severe denude and degeneration of gastric mucosa were observed in control groups but in Opae-san administrated groups the lesions were remarkably decreased compared to control groups.

Background: Gastric cancer (GC) is the second cause of cancer related death in the world. It may develop by progression from its precancerous condition, called gastric atrophy (GA) due to gastritis. The aim of this study was to evaluate the accuracy of serum levels of pepsinogens (Pg) and gastrin-17 (G17) as non-invasive methods to discriminate GA or GC (GA/GC) patients. Materials and Methods: Subjects referred to gastrointestinal clinics of Golestan province of Iran during 2010 and 2011 were invited to participate. Serum levels of PgI, PgII and G17 were measured using a GastroPanel kit. Based on the pathological examination of endoscopic biopsy samples, subjects were classified into four groups: normal, non-atrophic gastritis, GA, and GC. Receiver operating curve (ROC) analysis was used to determine cut-off values. Indices of validity were calculated for serum markers. Results: Study groups were normal individuals (n=74), non-atrophic gastritis (n=90), GA (n=31) and GC patients (n=30). The best cut-off points for PgI, PgI/II ratio, G17 and HP were $80{\mu}g/L$, 10, 6 pmol/L, and 20 EIU, respectively. PgI could differentiate GA/GC with high accuracy (AUC=0.83; 95%CI: 0.76-0.89). The accuracy of a combination of PgI and PgI/II ratio for detecting GA/GC was also relatively high (AUC=0.78; 95%CI: 0.70-0.86). Conclusions: Our findings suggested PgI alone as well as a combination of PgI and PgI/II ratio are valid markers to differentiate GA/GC. Therefore, Pgs may be considered in conducting GC screening programs in high-risk areas.

To determine the effects of Mahaengeuigam-tang(MHEGT) on obesity, the obesity-related factors (gastrin, CGRP, ghrelin, glucagon-like peptide-1, insulin, orexin, leptin, serotonin, NPY) were investigated in the stomach, pancreas, brain of mice by immunohistochemical methods for 4 weeks after Mahaengeuigam-tang(MHEGT) administration. The change of boy weight decreased in MHEGT administered group than that of control group. The immunohistochemical density of the gastrin and CGRP positive cells on pylorus of stomach increased in MHEGT administered group than that of control group. The number of ghrelin immunoreactive cells on stomach decreased in MHEGT administered groups than that of control group. The immunohistochemical density of GLP-1 in the pancreas decreased in MHEGT administered group than that of control group. The immunohistochemical density of insulin positive cells in the pancreas decreased in MHEGT administered group than that of control group. The immunohistochemical density of orexin and NPY positive neurons in the diencephalon was slightly stronger in MHEGT administered group than that of control group. The immunohistochemical density of serotonin and leptin positive neurons was stronger in MHEGT administered group than that of control group. These results demonstrate that Mahaengeuigam-tang(MHEGT) increased the immunohistochemical density of factors related to appetite inhibitors, and decreased the immunohistochemical density of factors related to stimulator of food intake in stomach, pancreas and brain.

Moxa-combustion therapy make use of heat stimulus and chemicals result form when cauterize the skin with moxa cones to medical cares. However, recently moxibustion have been utilized less than acupuncture for treatment of disease in a practicing oriental physicians. To determine variable parameters (the numbers, the times, the quantities, the locations) affected moxibustion's effects, the gastrin serum level in rats were observed. In experiment, male Spraque-Dawley rats (body wt. 140-160g) were selected. Anything is performed to normal group. Control group were only anesthetized with inhalation in normal group. Experimental group were anesthetized and cauterized with moxa at BL21 by way of direct moxibustion. The size of moxa cone is 1.6±0.2㎎. The moxibustion as 5 times a day for five days has shown most significant effects and the moxibustion as a aquantity of 1, 5, 10 times moxa united one respectly, inverse to quantity in effects. The moxibustion for five days has also shown an most significant effects. The moxibustion at unilateral acupoints BL21 have less effects than bilateral one and these effects had no difference between control group after vagotomy. This results indicate that moxibustion's effects are not direct proportion to moxa cone size and frequency but imply that there is adequate value of moxibustion.

The regional distribution and relative frequency of gastrointestinal endocrine cells were studied immunohistochemically in the gastrointestinal mucosa and pancreas of the fresh water turtle. Ten kinds of endocrine cells were identified in the gastrointestinal tract. Cholecystokinin-8-, bovine pancreatic polypetide-and glucagon-immunoreactive cells were seen throughout the gastrointestinal tract, also among them cholecystokinin-8-immunoreactive cells were most predominant in segment III. Although gastrin- and gastrin/cholecystokinin-immunoreactive cells were found from segment III to VI and X, respectively, they were numerous in segment III. Somatostatin-immunoreactive cells were observed from segment I to VII. 5-hydroxytryptamine- immunoreactive cells were detected in segment I, III, VIII, IX and X. Human pancreatic polypeptide-immunoreactive cells were demonstrated in segment V, VI, VIII, IX and X. Insulin-immunoreactive cells were found from segment III to X except for segment VIII, but rare in segment VII. Neurotensin-immunoreactive cells were found to be restricted to segment VIII, IX and X. No porcine chromogranin-, substance P- and bombesin-immunoreactive cells were detected throughout the gastrointestinal tract of the fresh water turtle. Although typical mammalian pancreatic islets encapsulated by connective tissue were not present in this species, five kinds of endocrine cells-glucagon, insulin, somatostatin, bovine pancreatic polypeptide and 5-hydroxytryptamine-were found in forming small or large groups and scattered in the exocrine gland region. However porcine chromogranin- and motilin-immunoreactive cells could not be demonstrated in the pancreas.

To determine the effects of Banggihwanggi-tang(BGHGT) on obesity, the obesity-related factors[gastrin, calcitonin gene related peptide(CGRP), serotonin, ghrelin, obestatin, glucagon-like peptide-1(GLP-1), insulin, orexin, leptin] were investigated in the stomach, pancreas, brain of mice by immunohistochemical(IHC) methods for 4 weeks. The change of body weight was more reduced in BGHGT administered group than that of control group. The IHC density of the gastrin and CGRP positive cells on pylorus was higher in BGHGT administered group than that of control group. The number of ghrelin immunoreactive cells on stomach was lower in BGHGT administered group than that of control group. The IHC of GLP-1 positive cells did not observe in the stomach of BGHGT administered groups. The IHC density of GLP-1 in the pancreas was lower in BGHGT administered group than that of control group. The IHC density of insulin positive cells in the pancreas was lower in BGHGT administered group than that of control group. The IHC density of orexin positive neurons in the diencephalon was slightly higher in BGHGT administered group than that of control group. The IHC density of NPY and leptin positive neurons was slightly higher in BGHGT administered group than that of control group. The IHC density of serotonin positive neurons was higher in BGHGT administered group than that of control group. Therefore, we conclude that BGHGT activates appetite inhibitor through appetite related enteroendocrine cells and neuropeptides in stomach, pancreas and brain, and this activation may also be responsible for the inhibition of feeding behavior.

Background: Prior series investigated the expression of prepro-gastrin releasing peptide (prepro-GRP) in the peripheral blood of lung cancer patients. Our aim was to assess any prepro-GRP role as a prognostic factor for small cell lung cancer (SCLC) and NSCLC and correlations with clinical presentation and treatment outcome. Methods: A prospective study was conducted during the time period from the beginning of January 2012 till the end of January 2014. Prepro-GRP expression was analysed using a nested RT-PCR assay in peripheral blood of 62 untreated lung cancer patients attending the National Cancer Institute (NCI), Cairo University, and 30 age and sex matched healthy volunteers. Results: Among the 62 lung cancer cases, there were 24 (38.7%) SCLC, and 38 (61.3%) NSCLC (10 squamous cell carcinomas, 12 adenocarcinomas, 11 large cell carcinomas, 4 undifferentiated carcinomas, and 1 adenosquamous carcinoma). Twenty six patients (41.9%) were prepro-GRP positive. Prepro-GRP expression was higher (58.3%) among SCLC patients compared to NSCLC (squamous cell carcinoma (15.4%), large cell carcinoma (36.4%), and adenocarcinoma (25%)). Mean OS among prepro-GRP negative cases was longer than that among preprogastrin positive cases (17.6 vs 14.9 months). The mean PFS durations among preprogastrin negative versus positive cases were 7.7 vs 4.6 months (p= 0.041). No difference in response to chemotherapy was identified between the groups (p=0.983). Conclusion: Prepro-GRP is suggested to be a useful prognostic marker for lung cancer patients, especially with the fast- growing, bad prognostic SCLC type. More studies should aim at detailed understanding of the mechanisms of prepro-GRP action and its use in monitoring the response to treatment in a larger cohort.

This study was performed to investigate the effect of promoting gastrointestinal function and inhibiting of decreasing body temperature of ginger extract(Zingiber officinale) in rats. In order to elucidate the gastrointestinal function and inhibiting effect of body temperature of native ginger and improved ginger, water extracts of ginger were orally administrated into rats. The results are as follows: The gastrointestinal transit time was significantly decreased in native ginger(7.66hrs) and improved ginger(7.72hrs) extract administrated groups compare to control group(8.44hrs). The mean red faecal weight was increased in native ginger(30.6%) and improved ginger(31.1%) extract administrated groups compare to control group(24.9%) for 24hrs. Inhibiting effect of decreasing body temperature induced by serotonin was increased in native ginger($1.116^{\circ}C$) and improved ginger($1.416^{\circ}C$) extract administrated groups compare to positive control group($0.384^{\circ}C$) during 40 minutes. Gastrin and CGRP immunoreactive density was more strongly expressed in native ginger and improved ginger extract administrated groups compare to control group. Serotonin immunoreactive density was more weakly expressed in native ginger and improved ginger extract administrated groups compare to control group. These results suggest that ginger extracts may enhance physiological activity such as gastrointestinal motility, protection of mucosa and gastric acid secretion in gastrointestinal tracts, and inhibits decreasing body temperature
