Combination of pancreatin and papain was investigated on protid digestive activities: The protid digestive capacity of mixture was remarkably higher than the total one of both partial substances of the same amount as in the mixture. The activity of the mixture was the best at pH 5-9, temperature from 28OC to 55OC and above

The liquid substances extracted from medicinal herb at 0.3% concentration cause to stimulate protease activity of pepsin from 11% to 32% in order: frustus evodiarutaecarpa < fructus and sement amoni xanthiodis < rhizoma zingiber officinale < fructus cirtus sp. < radix sausurea galanga < radix coptis sp. < radix. Sausurea lappa or inula helenium. This liquid substances at 0.25% concentration also cause the stimutation of protease activity of pancreatin from 0.6% to 32% in order: Fructus evodia rutaecarpa< rhizoma keampferia galanga < radix comptix sp. < freuctus citrus sp. < rhizoma zingiber officinale < radix sausurea lappa or inula helenium. Only the liquid substances extracted from the Fructus et semen amomi xanthiodis reduce lightly protease activity of pancreatine preparation. The optimal stimulation of the enzyme activity depends on their concentration. The first results may raise a question about the traditional medicine combined with the western medicine in the treatment of digestive diseases.

Pancreaticoduodenectomy is the treatment of choice for adult periampullary lesions. However there has been no studies on the clinical outcomes of pancreaticoduodenectomy in children. To evaluate the clinical outcomes, records of 13 patients who underwent pancreaticoduodenectomy, from 1989 to 2009, at Seoul National University Children's Hospital were reviewed. Mean follow up period was 83 (2-204) months, the male to female ratio was 1:3.3, and the mean age was 11 (2-14) years. Ten patients underwent PPPD and 3 patients had Whipple's operation. The postoperative diagnosis included solid pseudopapillary tumor (9), cavernous hemangioma (1), pseudocyst (1), benign cyst (1), pancreatic disruption (1). Two patients developed postoperative adhesive ileus and among them one patient required operative intervention. Four patients required pancreatin supplementation due to steatorrhea and other gastrointestinal symptoms. There were no postoperative mortality during the follow up period and no evidence of recurrence in SPT patients. This study demonstrates that the pancreaticoduodenectomy procedure in children is not only feasible but also safe, with no mortality and an acceptable complication rate.

A 1. 8-year-old intact female Maltese dog was presented because of a history of chronic diarrhea, polyphagia, weight loss, and coprophagia. The patient was severely emaciated and evacuated very moist and four-smelling, yellow feces. Fecal stain with Sudan III revealed numerous lipid droplets. Result of fat absorption test showed aldigestion. A definite diagnosis was made based on trypsin-like immunoreactivity assay in serum which was low enough to be diagnosed as an exocrine pancreatic insufficiency. After pancreatic enzyme supplement with porcine pancreatin powder, the clinical signs were disappeared. This case report documents clinical manifestations, diagnostic tools, treatment and efficiency of oral pancreatic enzyme replacement therapy of exocrine pancreatic insufficiency in a Maltese dog.

AIMTo know the effect of cysteamine on the pancreatic secretion and enzyme activity in geese.

METHODSEight adult geese fitted chronic pancreatic and duodenal cannulas were used to evaluate the effect of cysteamine (CS) on the pancreatic secretion and enzyme activity. The experiment was consist of control and treated phase. CS was added in the diet at the dosage of 100 mg/kg bw on the first day of treated phase. The birds were free fed at daytime (8:00-20:00) and fasted at nighttime (20:00-8:00). The pancreatic juice samples were collected continuously for three days in each phase.

RESULTSCS increased the average rate of pancreatic secretion by 240.16% (P < 0.01), in which that of daytime was elevated by 234.45% (P < 0.01), while that of nighttime elevated by 253.70% (P < 0.01). The secretion volume at daytime was more than that of night. CS increased trypsin activity by 49.05% (P < 0.01), whereas lipase and amylase activity was reduced by 25.44% (P < 0.01) and 21.95% (P < 0.01) separately. The one hour total activity of trypsin, lipase and amylase were elevated by 406.88% (P < 0.01), 153.58% (P < 0.01) and 166.59% (P < 0.01) respectively. Ratios of pancreatic secretion were different between day and night.

CONCLUSIONThese results indicate that CS can affect the pancreatic juice secretion and pancreatic enzyme activity by depleting the somatostatin, so that benefits to improve the digestive foundation and supply more nutrition for quickly growing in geese.

A series of experiments on various factors which induce optimal in vitro excystation of the metacercariae of Metagonimus yokogawai isolated from the fish, Plecoglossus altivelis was conducted and the following results were obtained. The metacercariae used in this experiment were isolated by the digestion technique therefore all of them were pretreated with the acid-pepsin solution before being applied to the various tests. No excystation occurred when the metacercariae were placed in a salt solutions such as physiological saline, Tyrode solution and Veronal, Tris buffers alone or in combination. The metacercariae underwent complete excystation in the trypsin and pancreatin solution in Tris buffer within an hour at 38 degrees C. The best results were obtained in 0.8-0.9% trypsin solutions, pH 8.0-8.6 and at 38-40 degrees C, approximately one hundred per cent excystation occurred in 40 minutes. Not only temperature but also hydrogen ion concentration played an important role causing excystation of the metacercariae in trypsin-Tris buffer solution. However, bile salts were not responsible for the excystation. Agitation effect on the excystation was tested as a mechanical stimulus and it was found that the shaking stimulus accelerated the excysting mechanism, compared with the metacercariae on which it was not imposed. It is concluded that the metacercariae pretreated in the acid pepsin solution demonstrates an essential requirement for the enzyme solution such as trypsin or pancreatin, provided with the optimum conditions of temperature and hydrogen ion concentration in excysting medium.

This study aims to observe different factors which affected the bionic enzymatic hydrolysis of icariin into baohuoside I and to optimize the reaction conditions in order to provide research foundation for building a novel bionic enzymolysis drug delivery system. To simulate the environment in vivo, 37 degrees C was set as the temperature and artificial intestinal juice and gastric juice were selected as the buffer solutions. Taking the conversion of baohuoside I as index, the effects of the kinds of enzyme, enzyme activity, substrate concentration, reaction time, pancreatin in artificial intestinal juice and surfactant on the conversion of baohuoside I were investigated. The results showed that cellulase, beta-glucosidase and snailase were all inactive in artificial gastric juice and no baohuoside I generated. Pancreatin in artificial intestinal juice couldn't significantly influence the activity of beta-glucosidase or snailase (P > 0.05), but noticeably decrease the activity of cellulase (P < 0.05). In artificial intestinal juice, the conversion of baohuoside I was highest by using beta-glucosidase, and the optimum reaction conditions were determined as follows: enzyme activity 10 U x mL(-1), substrate concentration 1 mg x mL(-1), 3 g x L(-1) rhamnolipid and reaction time 3 h. Under this condition, the conversion of baohuoside I was 99.8%.

Cases of acute pancreatitis induced by organophosphate intoxication are encountered occasionally in clinics, but very few of them develop into severe pancreas necrosis and irreversible pancreatic function impairment. Here, we report a 47-year-old female organophosphate poisoning case after ingestion of massive insecticides; she was considered to have total necrosis and function failure of the pancreas via serum amylase test, glucose level test, and CT imaging. The patient exhibited no relief under the regular medicine treatment, which included sandostatin, antibiotics, intravenous atropine, and pralidoxime methiodide. She received percutaneous catheterization and drainage of pancreatic zone to expel hazardous necrotic waste, also by which the pathogenic evidence was obtained and the antibiotics were adjusted subsequently. The patient recovered gradually, was discharged after 2 weeks, and was prescribed with oral pancreatin capsules before meals and hypodermic insulin at meals and bedtime to compensate the impaired pancreatic function.
