The present study was undertaken in order to elucidate the effects of pretreatment with nicotinamide on changes in serum glucose level, body weight, water consumption, serum insulin concentration, and the activity of pancreatic enzyme in rats treated with streptozotocin (STZ). Histological studies were also carried out to evaluate the effects on pancreatic tissues and Langerhans's islet cells. Nicotinamide pretreatment in STZ diabetic rats inhibited the rise of fasting serum glucose concentration and water consumption. Pretreatment with nicotinamide significantly increased the concentration of serum insulin and body weight changes compared to the STZ-treated group. Pancreatic lipase and trypsin activities were increased, but amylase activity was decreased and pancreatic $\beta$ -cell was destroyed by STZ. Pvetreatment with nicotinamide prevented these STZ-induced changes. These results suggest that nicotinamide pretreatment supresses STZ-induced changes in pancreatic enzymes by preventing $\beta$-cell destruction and therefore maintaining a normal serum insulin revel.

The purpose this study was to investigate the influences of 5% mung bean (Phaseolus aureus L.) on BUN and enzyme activities in serum of hyperlipidemic rats. Sprague-Dawley(SD) rats (24 male) were divided into four groups, namely the BD group(normal-nonhyperlipidemic diet), BM group(normal-nonhyperlipidemic diet+5% mung bean), BH group(control-hyperlipidemic diet), and BHM group(hyperlipidemic diet+5% mung bean). Serum concentrations of blood urea nitrogen (BUN) and uric acid were significantly decreased (p<0.05) by mung bean supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of mung bean diet group were significantly decreased (p<0.05). The catalase activity in serum of mung bean supplementation group was significantly increased than hyperlipidemic diet (p<0.05). In vivo experiment with hyperlipidemic rats showed that ingestion of mung bean were effective in kidney and hepatic functional enzyme activities. Which suggests that mung bean material could be used for further studies as a potential source for nutraceutical foods.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

To investigate the effect of intravenous ethanol administration on pancreatic exocrine secretion, we measured volume and protein amount in pancreatic juice and assayed amylase activity and phospholipase $A_2$ activity in pancreatic fragments and serum. Acute pancreatitis induced by obstruction of common bile-pancreatic duct (CBPD) and caerulein infusion (5 $\mu\textrm{g}$/kg/hr) showed typical characteristics, such as hyperamylasemia and pancreatic edema and increase of phospholipase $A_2$ activity in pancreatic fragments and serum. Intravenous ethanol infusion (50 mg/kg/hr) significantly stimulated pancreatic exocrine secretion, but such a stimulatory effect of ethanol disappeared at dose of 100 mg/kg/hr without typical symptoms of acute pancreatitis. In microscopic examination, there were no typical changes of edematous pancreatitis in ethanol administrated rats. These results suggest that acute ethanol administration has dual effect on exocrine pancreatic secretion: low dose of ethanol (50 mg/kg/hr) stimulates pancreatic exocrine secretion, whereas high dose of ethanol (100 mg/kg/hr) does not without typical changes of edematous pancreatitis.

The control of intestinal α-amylase and α-glucosidase is an effective therapeutic strategy for prevention of post-prandial hyperglycemia associated with diabetes mellitus. The objective of this study was to evaluate the anti-diabetes activities of Korean edible seaweed against α-amylase and α-glucosidase, two carbolytic enzymes involved in serum glucose regulation. Of the 41 species initially screened, Cladophora wrightiana var. minor, Eisenia bicyclis, Ecklonia cava, Ishige foliacea, and Ishige okamurae exhibited the strongest inhibitory activities from brown seaweeds. Asparagopsis taxiformis showed the strongest inhibitory effects from red seaweeds. The results of this study suggest that the crude brown seaweed extracts (C. wrightiana var. minor, E. bicyclis, E. cava, I. foliacea, and I. okamurae) and crude red seaweed extracts (A. taxiformis) may have beneficial effects suppressing the rise in postprandial hyperglycemia through the inhibition of α-amylase and α-glucosidase.

The purpose this study was to investigate the influences of 5% turmeric (Curcuma longa L.) supplementation on enzyme activities such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase, lipase and catalase in serum of dyslipidemic rats. Sprague-Dawley (SD) rats (24 male) were divided into four groups, namely the ND group (normal-nondyslipidemic diet), NT group (normal-nondyslipidemic diet+5% turmeric), DD group (control-dyslipidemic diet), and DT groups (dyslipidemic diet+5% turmeric). Serum concentrations of blood urea nitrogen (BUN), creatinine and uric acid were significantly decreased (p<0.05) by turmeric supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of turmeric diet group were significantly decreased (p<0.05). The catalase activity in serum of turmeric supplementation group was significantly increased than dyslipidemic diet (p<0.05). In vivo experiment with dyslipidemic rats showed that ingestion of turmeric were effective in kidney and hepatic functional enzyme activities. Which suggests that turmeric material could be used for further studies as a potential source for nutraceutical foods.

Cellulase from Aspergillus niger, (${\alpha}$-amylase from Bacillus sp. and protease from Bacillus globigii were used as enzyme sources in this study to examine how their respective substrates protect them in two kinds of simulated gastrointestinal tract digesting processes. Avian total digest tract simulation test showed that filter paper, Avicel and cellulose resulted in 7.7, 6.4 and 7.4 times more activity than of unprotected cellulose, respectively. Protease with addition of casein, gelatin or soybean protein showed no significant protection response. Starch protected amylase to be 2.5 times activity of the unprotected one. Monogastric animal total tract digestion simulation test showed that filter paper, Avicel and cellulose resulted in 5.9, 9.0 and 8.8 times activity of unprotected cellulase, respectively. Casein, gelatin and soybean protein resulted in 1.2, 1.3 and 2.0 times activity of unprotected protease, respectively. Starch did not protect amylase activity in monogastric animal total tract simulation. Protection of mixed enzymes by substrates in two animal total tract simulation tests showed that filter paper in combination with soybean protein resulted in 1.5 times activity of unprotected cellulose, but all substrates tested showed no significant protection effect to protease. Soybean protein and starch added at the same time protected the amylase activity to be two times of the unprotected one. Test of non-purified substrate protection in two animal total digest tract simulation showed that cellulase activity increased as BSA (bovine serum albumin) concentration increased, with the highest activity to be 1.3 times of unprotected enzyme. However, BSA showed no significant protection effect to protease. Amylase activity increased to 1.5 times as BSA added more than 1.5% (w/v). Cellulase activity increased to 1.5 times as soybean hull was added higher than 1.5%. Amylase had a significant protection response only when soybean hull added up to 2%. Protease activity was not protected by soybean hull to any significant extent.

The levels of activities of amylase, lipase and trypsin in both the pancreatic tissue and serum of 18 species of vertebrate animals were measured and enzymologically compared with each other. 1) The value of amylase in the pancreas of experimental mammalia has been found decreasing in the order pig, rat, dog, cat, rabbit and cow; that of pancreatic lipase has been found decreasing in the order of pig, dog, cat, rat, rabbit and cow; and that of trypsin has been found decreasing in the order of pig, cow, dog, rat, rabbit. Thus the value of all the above three kinds of enzymes were observed highest in pig, but in cow amylase and lipase were observed lowest while trypsin were observed considerably high. 2) In view of diets, the comparatively high values of pancreatic enzyme were observed in the ommivorous animals such as pig, rat, dog, while the values observed low in the herbivorous animals, such as cow and rabbit. 3) In the bovine, the values were observed moderately high except lipase which were found comparatively low. 4) In the Reptilia and Amphibia such a mud turttle and frog, the values were shown in similar measure with each other, that is, the pancreatic amylase and trypsin were observed considerably high while the lipase was found low. 5) In the species of Reptilia such as a viper and snake, the activities of pancreatic enzymes were not detected. But in the tissue of liver, stomach, activities of the enzymes were found considerably high. Lacertilia animals such as lizard the values of pancreatic enzymes were little observed. 6) In the fish in which the pancreatic tissue is scattered in the liver, the pancreatic enzymes were found in the liver tissue considerably higher than in the other tissues but lower than in the warm-blooded animals, especially the lipase was lower. 7) In generally the values of serum amylase and lipase were observed higher than those of man; and even in the cold-blooded animals in which the values of pancreatic enzymes were shown low or none, the values were also observed high. 8) The above three kinds of pancreatic enzyme values of those experimental animals have shown a tendency of higher degree in higher taxa than in lower taxa according to taxonomical order. 9) In view of tissue, the pancreatic cell was observed large in the mammalian animals such as rat and pig and cytoplasm was also abundantly contained in the acinous cell; and the bovine and the snake haave the pancreatic cells of the similar rosette form the comparatively large acinous cells of long rhombic form in the comparatively large acinous cells of long rhombic form in which the spindle shaped neucleus and the abundant cytoplasm were contained. In the fish the pancreatic cell were found scattered in the liver in which the very large pancreatic islet were found.
