Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP) would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP) and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘) which is the alarm point of the Stomach Meridian, and ST36 (足三里), which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-${\beta}1$ was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-${\beta}1$. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol-induced acute gastric ulcer.

The conception of 'earth(土)' belonging to the five evolutive phases(五行) is cognized that it is not partial to any side differing from other four phases and it can control other four phases so, it is the first gate to enter the process of changes. In the five organs(五臟), the spleen come under the earth phases and it have been very importantly considered for past to now in oriental medical history, for example by Li Dongyuan(李東垣). In this study, the results are summarized as the followings. 1. The term of the acquired constitution(後天) made by So-ong(邵雍), a scholar in the north so-dynasty, is used in the study of the book of changes(易經). And he said "The inborn constitution(先天) is the law of the nature itself and, the acquired constitution(後天) is the law of making the changes with the nature." In the myung-dynasty Li jungjae(李仲梓) made extract from this remarks 10 define that the spleen is the basis of the acquired constitution. So it considered that the the idea of changes(易) had an effect on the oriental medicine. 2. The one element of five phases, earth is the center of the changes and it composes the power of life with the sangsu(生數)-1, 2, 3, 4, and the sungsu(成數)-6, 7, 8, 9. In this process, the earth is the basis of the changes of the five phases. At the same time the spleen carry out the important physiological role in the humanbody controlling the other four organs. 3. In the change of the universe, the repetitionary movement of Yin(陰) and yang(陽) is the action of earth and it means illimitable division. In the course of this division all things change to new phases for example, the food changes 10 the ki(氣) through the action of spleen and stomach. So the organ of spleen and stomach is the space that the action of change occur. 4. Consequently the conception of bi(脾) is close to the pancreas that the spleen. And the duodenum is close to the conception of stomach because the space is the site of mito(未土). 5. The action of yin and yang in the ancient taegukdo(太極圖) is close 10 the connection of N-pole and S-pole. In the humanbody the two power is compared to the action of spleen and kidney, that means expansion and contraction. Also it means the inborn constitution and the acquired constitution so, it applyed to the all things in the universe.

In the present study, we characterized the non-vascular smooth muscle relaxant effects of a novel benzoyran derivative ,SKP-450 (2-[2'(1',3'-dioxolone)-2-methyl-4- (2'-oxo-1'-pyrrolidinyl) -6-nitro-2H-1- benzopyran) and its metabolite, SKP-310, in comparison with levcromakalim (LCRK). In the rat stomach fundus, the spontaneous motility stimulated by $10^{-6.5}\;M$ bethanechol was completely eliminated not only by $10^{-7}\;M$ SKP-450 but also by $10^{-6}\;M$ LCRK, which were blocked by $10^{-6}\;M$ glibenclamide. The inhibitory effect of SKP-450 $pD_2,\;3.94{\pm}0.66)$ was much less than LCRK $(pD2,\;5.73{\pm}0.38,\;p<0.05)$. In the bethanechol $(10{-6.5 }\;M)-stimulated$ urinary bladder, the tonus was decreased in association with elimination of spontaneous motility by $10^{-7}\;M$ M SKP-450 and $10^{-6}\;M\;LCRK\;(pD2,\;6.77{\pm}0.06)\;(P<0.05)$, which were inhibitable by $10^{-6}\;M$ glibenclamide. The inhibitory effect of SKP-450 $(pD2,\;7.66{\pm}0.05)$ was significantly more potent than that of LCRK $(pD2,\;6.77{\pm}0.06,\;p<0.05)$. In the rat uterus stimulated by $PGF_{2\alpha}\;(10^{-7}\;M)$, both increased tonus and spontaneous motility were eliminated by $10^{-6}\;M$ LCRK with slight depression of the tonus, but not by SKP-450 $(10^{-5}\;M)$. The stimulated trachea of guinea-pig by $10^{-6.5}\;M$ bethanechol was moderately suppressed by SKP-450 $(10^{-6}{sim}10^{-5}\;M)$ but little by SKP-310. In association with the relaxant effects, SKP-450 $(10^{-6}\;M)$ and LCRK $(10^{-5}\;M)$ caused a significant stimulation of the $^{86}Rb$ efflux from rat urinary bladder and stomach fundus, which were antagonized by $10^{-5}\;M$ glibenclamide, whereas the $K^+$ channel openers could not exert a stimulation of the $^{86}Rb$ efflux from rat uterus. In conclusion, it is suggested that SKP-450 exerts potent relaxant effects on the urinary bladder detrusor muscle and duodenum, whereas it shows much less effect on stomach fundus and uterus as contrasted to LCRK.

In-utero exposure to valproic acid (VPA) has been known as a potent inducer of autism spectrum disorder (ASD), not only in humans, but also in animals. In addition to the defects in communication and social interaction as well as repetitive behaviors, ASD patients usually suffer from gastrointestinal (GI) problems. However, the exact mechanism underlying these disorders is not known. In this study, we examined the gross GI tract structure and GI motility in a VPA animal model of ASD. On embryonic day 12 (E12), 4 pregnant Sprague-Dawley (SD) rats were subcutaneously injected with VPA (400 mg/kg) in the treatment group, and with phosphate buffered saline (PBS) in the control group; the resulting male offspring were analyzed at 4 weeks of age. VPA exposure decreased the thickness of tunica mucosa and tunica muscularis in the stomach and ileum. Other regions such as duodenum, jejunum, and colon did not show a significant difference. In high-resolution microscopic observation, atrophy of the parietal and chief cells in the stomach and absorptive cells in the ileum was observed. In addition, decreased staining of the epithelial cells was observed in the hematoxylin and eosin (H&E)-stained ileum section. Furthermore, decreased motility in GI tract was also observed in rat offspring prenatally exposed to VPA. However, the mechanism underlying GI tract defects in VPA animal model as well as the association between abnormal GI structure and function with ASD is yet to be clearly understood. Nevertheless, the results from the present study suggest that this VPA ASD model undergoes abnormal changes in the GI structure and function, which in turn could provide beneficial clues pertaining to the pathophysiological relevance of GI complications and ASD phenotypes.

This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

This paper dealt with the situation and the hatch rate of bot's eggs on the equine hairs in Cheju horse with the species grouping of the bot flies of equine(genus Gasterophilus). The prevalence and infection dynamics of Gasterophilus spp. larvae was also evaluated in the equine alimentary canal submitted in this laboratory for the necropsy or from the abattoir. Samples including Gasterophilus spp. larvae, bot's flies and its eggs, which were collected from the alimentary canal and equine hairs, respectively, were studied and classified by morphology. The morphologic feature of the spines of Gasterophilus larvae were studied by scanning electron microscope. 1. Gasterophilus intestinalis larvae concentrated in the nonglandular portions of the stomach. The infection of second-, and third stage larvae were common in November, and from January to October, respectively. Gasterophilus nasalis larvae were commonly identified on the gastric pylorus and upper portion of duodenum. Second stage larvae were found from October to December, and 3rd stage larvae, from January to September. 2. The hatch rate of laid eggs of Gasterophilus intestinalis was 28.4%, and that of Gasterophilus nasalis was 79.5%. The hatch rate of Gasterophilus intestinalis eggs was highest(62.5%) in December. The hatch rate of laid eggs were higher in the region of scapula(64.0%) and limbs(62.5%) than on the maned hairs. The eggs of Gasterophilus nasalis were completely hatched by October. 3. Eight hundred five Cheju horses examined in this study were infected with the eggs of Gasterophilus spp. Gasterophilus intestinalis eggs on the body regions from sixty horses were recognized in phalangeal (14.4%), in abdominal(13.8%), metacarpal, brachial and cervical regions. Gasterophilus nasalis eggs were uncommon and recognized in submandibular regions(1.4%). 4. In conclusion, the infection of imago, larvae and eggs of both Gasterophilus intestinalis and Gasterophilus nasalis were indentified in cheju horse.

A total of 30 cases of the peptic ulcer in children, who underwent operations from January 1981 to December 1995 because of complications at Department of the Surgery, Chonbuk National University Medical School, is reviewed. Twenty-three were males (76.7%), 7 females (23.3%) and male was preponderant at 3.3:1. There were 25 cases (83.3%) age 10 to 15 years, 3(10.0%) between 2 and 9 years, and 2 (6.7%) below 2. The ulcer was located at duodenum in 27(90.0%), and at stomach in 3 cases (10.0%). Complications were perforation in 19 cases (63.3%), pyloric obstruction in 9 (30.0%) and bleeding in 2 (6.7%). For perforation, truncal vagotomy with pyloroplasty was done in 11 cases, truncal vagotomy with hemigastrectomy and gastrojejunostomy in 6, and simple closure in 2 cases. For obstruction, truncal vagotomy with hemigastrectomy and gastrojejunostomy was done in 5, and truncal vagotomy and pyloroplasty in 3 cases. For bleeding lesions, truncal vagotomy and pyloroplasty was performed in 2 cases. Ten postoperative complications developed in 9 patients: adhesive ileus in 5, recurrence in 2, pneumonia 2, and wound seroma 1 case. One patient developed a primary duodenal perforation and another a recurrent obstruction. Both of patients had symptoms for more than 3 years and were treated with truncal vagotomy and pyloroplasty for the primary operations. Hospital stay was 11.5 days for the patient with perforated ulcer, 11.0 days for the patient with pyloric obstruction, and 14.5 days for the child with bleeding. Average hospital period was 11.6 days. To reduce recurrences after operation, extensive procedure such as distal gastrectomy with vagotomy at the first operation should be considered in case with severe complication or with patients who have been symptomatic for long periods.

An 11 year-old male Korean short-haired cat was presented to local animal hospital due to weight loss, vomiting, and intestinal hypomotility. After the cat was euthanized by poor clinical outcomes, necropsy was performed at Animal and Plant Quarantine Agency. At necropsy, the stomach was enlarged and had some nearly complete pellet food and the yellow mucous contents. The lumen of the middle and lower parts of the jejunum became narrow. Histopathologically, medium-sized lymphoid cells with hyperchromatic nuclei enclosed by scant cytoplasm were diffusely proliferated from mucosa to serosa of the small intestine. These findings were mainly observed in the jejunum and slightly in the duodenum and ileum. The monomorphous lymphocytes were 1 to 1.5 times larger than red blood cells and had few mitotic figures. Metastasis of the tumor cells to other organs was not observed. In the result of immunohistochemical analysis for identifying the origin of tumor cells, CD3 was expressed, but $CD79{\alpha}$ was not detected in the infiltrated cells. This case was diagnosed as T cell intestinal lymphoma in a Korean short-haired cat based on the clinical signs, gross findings, histopathology, and immunohistochemistry.
