General pharmacological properties of urinary trypsin inhibitor (UTI) following intravenous administration of 1,000,000 units/kg were examined in terms of effects on central nervous system, cardiovascular system, respiratory system, gastrointestinal system in mice, rats and rabbits. Administration of UTI (1,000,000 units/kg, iv) had no effect on central nervous system; no influences on pentobarbital sleeping time, spontaneous activity, normal body temperature, chemoshock produced by pentylenetetrazole solution, writhing syndromes induced by 0.6% acetic acid solution, and motor coordination of mice. The administration of UTI (1,000,000) units/kg, iv) in rats had no effect on systolic blood pressure and pulse rate. UTI (500,000 units/kg, iv) given to anesthetized rabbits showed no effect on respiratory rate. However, it showed significant elevation of respiratory rate at the concentration of 1,000,000 units/kg. Gastric secretion of rat and intestinal motility of mice were not influenced by the dose of 1,000,000 units/kg. In terms of autonomic nervous system, the material did not show direct effect and inhibitory or augmentative action of histamine- or acetylcholine-induced contraction at the concentration of 2,000 units/ml in the isolated ileum of guinea pig.

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.

Sennoside A (erythro) and sennoside B (threo) are dianthrone glycosides and diastereomers. We investigated their abilities to prevent the gastric lesions associated with diseases, such as, gastritis and gastric ulcer. To elucidate their gastroprotective effects, the inhibitions of $HCl{\cdot}tOH$-induced gastritis and indomethacin-induced gastric ulcers were assessed in rats. It was observed that both sennoside A and sennoside B increased prostaglandin $E_2$ ($PGE_2$) levels and inhibited $H^+/K^+$-ATPase (proton pump). In a rat model, both compounds reduced gastric juice, total acidity and increased pH, indicating that proton pump inhibition reduces gastric acid secretion. Furthermore, sennoside A and B increased $PGE_2$ in a concentration-dependent manner. In a gastric emptying and intestinal transporting rate experiment, both sennoside A and sennoside B accelerated motility. Our results thus suggest that sennoside A and sennoside B possess significant gastroprotective activities and they might be useful for the treatment of gastric disease.

The pharmacological effects of an Ayurvedic diuretic drug 'Treenoponchomul' (TPM) was investigated in animal model. The pharmacological actions of the test drug along with that of the components thereof, on the Central Nervous System (CNS) were studied. The drug under study TPM showed little effect on the CNS, the same can not be said about the components. The most prominent CNS depressant effect was observed with Saccharum officinarum Linn. (EE) in that it lowered the spontaneous motor activity as well the exploratory -behavior of the animals. An exploration retarding effect of moderate degree, was evident with Imperata cylindrica Beauv. (UU), and Phragmites maxima Blatter & McCann (NN). Although the test drug did not alter the normal locomotor and/ or exploratory behavior of the treated animals, it did significantly (p<0.01) lower the locomotion of the amphetamine induced hyperactive animals. TPM along with its components (especially Desmostachya bipinnata Stapf. Root, KU), significantly reduced the gastro-intestinal motility of the treated animals (p<0.01). The test drug and its components lowered the body weight of the treated animals, on being administered chronically (30 days), with EE being the only exception.

General pharmacological studies of LB20304a (a mesylate salt form of a new quinolone antibiotic LB20304 following oral administration of 300 mg/kg and 1000 mg/kg, almost maximum tolerance dose in mice and rat, respectively, were performed in terms of effects on general behaviour, central nervous system, gastrointestinal system, and blood coagulation system in mice and rats. With regards to general behaviour of mice, at oral dose of 300 mg/kg, LB20304a reduced muscle tone and locomotor activity. In terms of CNS, at oral treatment of 300 mg/kg, LB20304a showed some analgesic effects in mice, and oral dose of 1000 mg/kg caused drop in normal body temperature of rat, while it enhanced the pentylenetetrazole-induced clonic convulsion to tonic convulsion and/or death in mice at the doses of unto 300 mg/kg. In addition, LB20304a increased hexobarbital-induced sleeping time two and three times in mice at oral doses of 20 mg/kg and 300 mg/kg, respectively. Rota-rod and traction test in mice were not influenced by the dose of 300 mg/kg and 200 mg/kg, respectively. LB20304a reduced gastric secretion of rat at dose of 1000 mg/kg, and increased intestinal motility of mice at dose of 300 mg/kg. In rats, blood coagulation index, such as PT (prothrombin time) and aPTT (activated partial thromboplastin time) were not affected by the treatment of upto 1000 mg/kg of LB 20304a.

A seven-month pregnant 15-year-old Thoroughbred mare presented with acute abdominal pain to Jeju National University Equine Hospital. At presentation, a nasogastric intubation revealed 10 L of gastric reflux; rectal palpation and ultrasound revealed dilated loops and thickening of the walls of the small intestine. An exploratory laparotomy revealed strangulation of the small intestine due to a large abdominal mass. The mass was double-ligated and resected blindly due to the short pedicle. An enterectomy was not performed as intestinal motility was detected following the mass removal. Histopathological examination confirmed that the mass was a lipoma, measuring 24 cm × 16 cm × 16 cm in size. On day 8 post-surgery, the mare was discharged without complications. This case report describes the diagnosis and treatment of strangulation of the small intestine by a pedunculated lipoma, thus providing useful information on lipoma in horses.

Serotonin, a biogenic amine widely found in many organisms, functions as both a neurotransmitter and hormone. Although serotonin is involved in various physiological processes, this study aimed to review its role in energy metabolism. Given that serotonin cannot cross the blood-brain barrier and is synthesized by two different isoforms of tryptophan hydroxylase in the central nervous system (CNS) and peripheral tissues, it is reasonable to assume that serotonin in the CNS and peripheral tissues functions independently. Recent studies have demonstrated how serotonin influences energy metabolism in metabolic target organs such as the intestines, liver, pancreas, and adipose tissue. In summary, serotonin in the CNS induces satiety and appetite suppression, stimulates thermogenesis, and reduces body weight. Conversely, serotonin in the periphery increases intestinal motility, stimulates gluconeogenesis in the liver, suppresses glucose uptake by hepatocytes, promotes fat uptake by liver cells, stimulates insulin secretion while suppressing glucagon secretion in the pancreatic islets, promotes lipogenesis in white adipose tissue, inhibits lipolysis and browning of white adipose tissue, and suppresses thermogenesis in brown adipose tissue, thereby storing energy and increasing body weight. However, considering that most experimental results were obtained using mice and conducted under specific nutritional conditions, such as high-fat diets, whether serotonin acts in the same way in humans, whether it will act similarly in individuals with normal versus obese weights, and whether its effects vary depending on the type of food consumed, remain unknown.

Dichloroisoproterenol(DCI) i; one of the well known ${\beta}$-adrenergic receptor blocking agents. According to Moran and Perkins, DCI has sympathomimetic like action in relatively low concentrations. Fleming and Hawkins confirmed that DCI acts upon the receptors concerned with positive chronotropic and inotropic actions in the heart. Vogins reported that DCI, in concentration of $5{\times}10^{-8}$ to $5{\times}10^{-6}g/ml$, had properties of sympathomimetic amine causing positive inotropic and chronotropic actions in normal rat atria. And James and Nadeau found that DCI had not only adrenergic blocking effect in moderate and higher concentrations, but it also blocked the effect on the sinus node by vagal stimulation and of directly administered acetylcholine in higher concentrations. As stated above by many authors, DCI has complicated actions according to its concentrations. Our aim at the present experiments was to study the effects of DCI to the action of ouabain and acetylcholine upon the excised rabbit atria, as well as to the action of barium chloride and acetylcholine upon the excised rabbit intestine. In addition, Pan ax Ginseng is widely used as tonics in oriental nations, its pharmacological action, however, has not been clearly established. So we atempted to investigate the effects of the water extract of Panax Ginseng to the action of ouabain and DCI upon both atria and intestine. The results obtained were as follows. 1) DCI has a negative inotropic effect on the excised rabbit atria at concentration of $10^{-5}$ and a positive inotropic effect at concentration of $10^{-6}$. 2) DCI (at concentration of $10^{-6}$) potentiates the positive inotropic effect of ouabain upon the excised rabbit atria. 3) DCI antagonizes the action of acetylcholine upon the excised rabbit atria. 4) The water extract of Panax Ginseng, at concentration of $10^{-3}$, decreases the contractile force of rabbit atria, and tends to slightly increase that of rabbit atria at $10^{-4}$. 5) The water extract of Panax Ginseng exhibits a synergistic action with ouabain on the contractile force of rabbit atria. 6) DCI, in concentrations of $10^{-7}{\sim}10^{-6}$, depresses the tone and amplitude of contraction of the excised rabbit intestine. The depression of the intestinal tone markedly appears in pretreatment with reserpine 2mg/kg 24 hours. 7) DCI antagonizes the contractile effect of barium chloride on the excised rabbit atria. 8) DCI has no significant influence on the action of acetylcholine upon the excised rabbit intestine. 9) The series of those evidences indicates that DCI has a sympathomimetic-like action and more over a relaxing action directly on the excised rabbit intestine. 10) The water extract of Panax Ginseng in concentrations of $10^{-4}{\sim}10^{-3}$, has transient depression of the intestinal tone, but later gradually recovers its normal motility: 11) The water extract of Panax Ginseng has a synergistic action with ouabain on the intestinal contractility.
