The effects of Bezoar Bovis on immune responses of ICR Mice were studied. In the present study, the Jerne hemolytic plaque assay (PFC) was used to evaluate the humoral immune response to sheep red blood cells, and macrophage regulatory function was measured by quantitating the production of molecules secreted by macrophages. Bezoar Bovis was given in single daily p.o doses for short term (1, 2 days) or long term (7, 14 days). PFC response for taken 3 days after short term exposure to Bezoar Bovis was increased. The production of nitirc oxide in macrophages was also stimulated. In contrast, long term exposure to Bezoar Bovis resulted in inhibitory effect of Bezoar Bovis on nitirc oxide, $TNF-{\alpha}$and IL-6 production in macrophages. These findings suggest that treatment with Bezoar Bovis may result in differential immunological effect depending on treatment schedule.

Objectives : The present study attempted to reveal the effects of the combination of Fel Ursi and Bezoar on the improvement of the function of the liver, through examining the effects of Fel Ursi, Bezoar, and Woong-Whang Tang composed of Fel Ursi and Bezoar. Method : Acute hepatitis was induced by galactosamine to rats, and then Fel Ursi, Bezoar Bovis, and Woong-Whang Tang were introjected to measure the influence of serums such as AST, ALT, ALP, ${\gamma}GT$, and lipid peroxide of liver tissues which are considered as the index of the function of the liver. Results : 1. Fel Ursi decreased the lipid peroxide of ALT, ${\gamma}FT$, and liver tissue and that of mitochondria in liver tissues of the rats with galactosamine-induced acute hepatitis, but it did not have any significant effect on AST and ALP. 2. Bezoar Bovis decreased the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues among serum of the rats suffering from acute hapatitis induced by galactosamine, but it did not have any significant effect on that of mitochondria of the liver tissues. 3. Woong-Whang Tang had a significant effects on the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues, and on the decrease of lipid peroxide of mitochondria, among serum of the rats suffering from acute hapatitis induced by galactosamine. Conclusion : Fel Ursi and Bezoar Bovis were judged to be effective on the acute hepatitis of the liver by galactosamine. In particular, Woong-Whang Tang which was composed of the combination of Fel Ursi and Bezoar Bovis was more efficient in the improvement of the function of the liver and the amount of lipid peroxide than the respective use of Fel Ursi or Bezoar Bovis.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.

A simple and sensitive method was developed for the quantification of free and conjugated bile acids in bezoar without prior hydrolysis. $3{\alpha}-Hydroxy$ bile acids are first oxidized to 3-keto bile acids in the reaction catalyzed by $3{\alpha}-hydroxysteroid$ $dehydrogenase(3{\alpha}-HSD)$. During this oxidative reaction, an equimolar quantity of nicotinamide adenine dinucleotide(NAD) is reduced to NADH and subsequently oxidized to NAD with concomitant reduction of nitrotetrazolium blue(NTB) to diformazan by the catalytic action of diaphorase. The diformazan has an absorbance maximum at 540 nm. The intensity of the color produced is directly proportional to bile acids concentration in the bezoar extracts. The optimum conditions for the enzymatic reaction such as effects of reaction time, reaction temperature and pH, and stability were investigated. Calibration plots for the sodium chelate observed to be linear and intra-, inter-assay analytical recovery of bile acids averaged $97.65{\pm}3.4%(S.D.)$. Therefore, it is considered that the quality control of total bile acids from bezoar or bezoar-containing liquid preparation using this simple and sensitive assay system will be acceptable. Also current bezoars and bezoar-containing liauid preparations were examined their total bile acids from this method.

The antihepatotoxic activity of Bezoar Bovis and Moschus was investigated by in vitro assay method using galactosamine and carbon tetrachloride-induced cytotoxicity in primary-cultured rat hepatocytes. The antihepatotoxic activity was evaluated by measuring the level of glutamate pyruvate transaminase and sorbitol dehydrogenase which were released from the necrotic hepatocytes to the culture medium. In galactosamine-intoxicated hepatocytes, the chloroform fraction of Bezoar Bovis reduced the level of glutamate pyruvate transaminase and sorbitol dehydrogenase resulting in 65% and 59% protection, respectively. The n-Hexane fraction of Moschus resulted in 45% and 40% protection, respectively in this system. In the case of carbon tetrachloride-intoxicated rat hepatocytes, Bezoar Bovis did not have significant effect and only the aqueous fraction of Moschus showed 42% and 40% protection, respectively.

Gastric bezoars are concretion of undigested material in the gastrointestinal tract. In the past, gastric bezoars were generally treated with surgical management. Recently, the efficacy of oral intake or endoscopic injection therapy with Coca-Cola has been reported. We report a case of a 47-year-old-man with huge gastric bezoar ($4{\times}2.5$ cm) that was successfully removed by endoscopic fragmentation with Coca-Cola injection. Compared with a single endoscopic fragmentation therapy, the combination therapy with Coca-Cola injection shortened the procedure time and reduced the complication associated with fragmented bezoar.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract; they usually occur in patients who have undergone gastric surgery and have delayed gastric emptying. Treatment options include dissolution with enzymes, endoscopic fragmentation with removal or aspiration, and surgery. Recently, the efficacy of nasogastric lavage or endoscopic infusion of Coca-Cola for the dissolution of phytobezoar have been reported. We report a case of phytobezoar successfully treated by oral administration and endoscopic injection of Coca-Cola. A 62-year-old woman was referred to Yeungnam University Hospital for epigastric pain. Upper gastrointestinal endoscopy revealed one very large, dark-greenish, solid bezoar in the stomach with gastric ulcer and duodenal bulb deformity. We performed endoscopic injection of Coca-Cola into the bezoar. The patient was instructed to drink four liters of Coca-Cola per day. At endoscopy two days later, the phytobezoar was easily broken into pieces. At endoscopy on the $11^{th}$ day of admission, the phytobezoar was decreased in size and removed by endoscopic fragmentation with a polypectomy snare. At follow up endoscopy after 13 days, the bezoar was completely dissolved.
