In order to investigate the effect of Daewhajungeum on the isolated organs, gastrointestinal tract and C.N.S., some kinds of experiments using mice and rats were done. The results were as follows; 1. Daewhajungeum showed the inhibitory effect on the smooth muscle contraction of the isolated ileum and colon induced by acethylchorine chloride and barium chloride in mice. 2. Daewhajungeum showed inhibitory effect on the contraction of the fundus-strip induced by acethylchorine chloride and barium chloride in rats. 3. The preventive effect on pyloric ulcer, indomethacin induced ulcer and ethanol-HCl induced ulcer of mice was recognized. 4. The effect on the acidity of gastric juice was suppressed, but the effect on the pepsin output was not recognized. 5. The transport ability of small and large intestine was significantly decressed. 6. The analgesic effect and the sedative effect were recognized so that the effect of the C.N.S was suggested.

To evaluate GC-rhEPO, human erythropoietin produced by recombinant DNA technique, its general pharmacological properties were investigated in experimental animals administering intravenously and in vitro test system. GC-rhEPO at doses of 70,700 and 7,000 IU/kg body weight had no influence on general behavior, spontaneous motor activity, thiopental-inducted sleeping time, writhing syndrome induced by acetic acid, strychnine-induced convulsions, charchoal meal propulsion in mice, and body temperature, gastric juice secretion, urine and electrolyte excretion in rats. In anesthetized rabbits, GC-rhEPO (70, 700 and 7,000 lU/kg, i.v.) did not alter respiratory rate, blood pressure, heat rate. In in vitro experiments, GC-rhEPO did not affect the contractions of the isolated ileum of guinea pigs and the muscle twitchs of isolated neuromuscular junction of the rats. In addition, GC-rhEPO did not affect the blood coagulation time and ADP-induced platelet aggregation in plasma of rabbits. Taken together, these results indicate that GC-rhEPO does not induce any adverse effects in the experimental animals.

Two experiments were conducted to investigate the effects of feeding single or combined probiotics on performance and intestinal microflora of broiler chicks for five weeks. Diets based on corn and soybean meal contained 21.50, 19.0% CP and 3,100, 3,150 kcal/kg ME for starting and finishing period, respectively. Lactobacillus salvarius isolated from chicks intestine(LSC), Lactobacillus salvarius isolated from piglet(LSP) Bacillus polyfermenticus(BP) were fed with alone and mixed ones at the level of 0.21 and 0.1% in experiment 1 and 2. Three hundred eighty four chicks were randomly assigned to eight treatment with four replicates of 12 chicks each per treatment. Weight gain, feed consumption, feed conversion ratio(FCR) were weekly measured for 5 weeks. The number of intestinal microflora was examined at the end of experiment. There were no significant different weight gain of all treatment in both experiments. Feed consumption were not shown consistency. Chicks fed LSC alone showed the lowest feed conversion ratio of all treatment in experiment 1, but was not consistency in experiment 2. The number of Lactobacillus spp. tended to increase in chicks ileum fed probiotics treatments, whereas it was not consistency in cecum. The number of ileal E. coli was not decreased in BP treatment.

Non-occlusive mesenteric ischemia (NOMI) encompasses all forms of mesenteric ischemia with patent mesenteric arteries. NOMI is commonly caused by decreased cardiac output resulting in hypoperfusion of peripheral mesenteric arteries. We report a case of NOMI secondary to hemorrhagic shock and rhabdomyolysis due to trauma. A 42-year-old man presented to our trauma center following a pedestrian trauma. On arrival, he was drowsy and in a state of hemorrhagic shock. He was found to have multiple fractures, both lung contusion and urethral rupture. An initial physical examination and abdominal computed tomography (CT) scan revealed no evidence of intra-abdominal injury. High doses of catecholamine were administered for initial 3 days due to unstable vital sign. On day 25 of hospitalization, follow-up abdominal CT scan demonstrated that short segment of small bowel loop was dilated and bowel wall was not enhanced. During exploratory laparotomy, necrosis of the terminal ileum with intact mesentery was detected and ileocecectomy was performed. His postoperative course was uneventful and is under rehabilitation.

This study was carried out to investigate the motor activity and glucose transport and metabolism of Gaewool-Whadam-Jian(GWJ) in rat gastro-intestinal tract. The motor activity of the rat gastro-intestinal tract has been investigated by means of measuring barium sulfate passage degrees. Atropine treatment significantly delayed barium sulfate transit, and GWJ pretreatment increased intestinal motor activity, but not significant. GWJ administration showed no toxicity to kidney and liver. Transport and metabolism of glucose were studied in everted sac of rat small intestine with incubation under several conditions. The transport and metabolism of glucose were greater at jejunum than ileum. So, everted jejunum of rat were used to study the effect of GWJ. When GWJ were treated, the concentration of glucose were higher than untreated group. This result was thought to be influenced by the glucose in GWJ. When 2, 4 dinitrophenol and phlorizin were treated, the transport and metabolism of glucose were decreased, but GWJ treated together, the concentration of glucose in serosal solution increased. Gastric juice secretion and total acidity significantly decreased by administration of GWJ through duodenum region. The mechanism of effect of GWJ was still unidentified, Dut through continuous investigation, the effect of GWJ should be investigated.

General pharmacological properties of AG 60 (mixture of acriflavine and guanosine (1:1, w/w)), which has anticancer effect, following intramuscular administration were examined in terms of effects on central nervous system, gastrointestinal system, cardiovascular system, respiratory system and autonomic nervous system in mice, rats, guinea-pigs and rabbits. AG 60 at the dose of 15 mgtg had no influences on pentobarbital sleeping time, spontaneous motor activity, chemoshock produced by pentylenetetrazole solution, writhing syndromes induced by 0.8% acetic acid solution, and motor coordination of mice. However, AG 60 at the dose of 7.5 and 15 mg/kg caused significant decrease of normal body temperature 1 and/or 2 h after the administration. No influence on body temperature was observed at 3.75 mg/kg in mice. Gastric secretion of rat and intestinal motility of mice were not influenced by the dose of 15 mg/kg. In terms of autonomic nervous system, AG 60 did not show direct effect and inhibitory or augmentative action of histamine- or acetylcholine-induced contractions at the concentration of 5 mg/L in the isolated ileum of guinea-pig. The administration of 15 mg/kg of AG 60 did not affect mean arterial blood pressure and heart rate in rat. AG 60 (15 mg/kg) given to anesthetized rabbits showed no effect on respiratory rate.

To investigate the regional distribution and relative frequency of the neurotensin-, pancreatic polypeptide(PP)- and gastrin/cholecystokinin(Gas/CCK)-immunoreactive cells in the gastrointestinal tract of the bullfrog(Rana catesbeiana) with developmental stages, group of bullfrogs subdivided into the tadpole with hindlegs, metamorphosed bullfrog with tail, 2 weeks after metamorphosed bullfrog and adult bullfrog, were stained by immunohistochemical methods (PAP methods). Neurotensin-immunoreactive cells were observed from the pylorus of the metamorphosed bullfrog with tail, but these cells were not detected after that periods. PP-immunoreactive cells were detected from the adult bullfrog in the pylorus, duodenum and ileum. These cells were most predominant in the pylorus. Gas/CCK-immunoreactive cells were observed from the adult bullfrog in the pylorus. According to these results, most of immunoreactive cells in the gastrointestinal tract of the bullfrog were appeared after the complete metamorphosed periods, in which the complete differentiation of structure of gastrointestinal tract were occurred, and variable changes of the regional distribution and relative frequency with developmental stages were observed.

The regional distributions and relative frequencies of the gastrin, secretin and pancreatic polypeptide(PP)-immunoreactive cells in the gastrointestinal tract of the fetus(180 days of gestation) of Korean native goat were studied with immunohistochemical(ABC) methods. Gastrin-immunoreactive cells were detected in fundus, pylorus and duodenum and these cells were most predominant in pylorus. Secretin-immunoreactive cells were observed in pylorus, duodenum and ileum. PP-immunoreactive cells were restricted to fundus. These immunoreactive cells were situated in surface epithelium and mucosal gland regions. The regional distribution and relative frequency of PP-immunoreactive cells was somewhat different to the adult Korean native goat. Immunoreactive cells in the surface epithelial regions were open typed cells which were spindle shaped cells but closed typed cells which were round or/to spherical shaped cells were observed in the mucosal gland regions.
