Purpose: To find progression and prognosis of pancreatitis developed in massive burn patients through retrospective analysis. Methods: A retrospective study was conducted on 32 patients with abnormal increase of serum lipase level among 2523 acute burn patients admitted to our burn center from January 1, 2017 to June 30, 2018. Pancreatitis in this study was defined as a serum lipase concentration level that is higher than 180 IU/L which is three times more than the normal level (less than 60 IU/L). In this study, a retrospective analysis was performed on patients with serum lipase level higher than 300 IU/L to better understand causality of burns and pancreatitis. Results: 32 patients (1.27%) had serum lipase level higher than 180 IU/L among 2523 acute burn subjects. And 13 patients (0.52%) of these 32 patients had serum lipase level elevated more than 300 IU/L. The study indicated serum lipase level was increased around 7 days after the injury. It returned to normal level early as after 1 to 2 weeks and late as after 4 to 6 weeks of injury. The serum amylase level was increased as similar modality as to the serum lipase level increase. The serum bilirubin, AST, ALT, LD, and GGT were also observed to be elevated when serum lipase was more than 1000 IU/L. Conclusion: The pancreatitis developed in burn patients are mostly as mild symptom. It could due to the ischemic injury and can easily be treated by a temporary fasting, TPN, and Gabexate intravenous injection.

Present experiments were undertaken in order to find out the most available diagnostic method for acute pancreatitis. Experimental dogs were divided into experimental group and control group. The experimental dogs were laparotomized and their pancreatic ducts were ligated for the induction of pancreatitis. The control dogs were laparotomized only for comparison. In addition to the complete blood count, serum amylase and lipase activities, serum glucose, total protein and albumin contents were measured daily for 11 days after the operation. Fecal fat droplet count by Sudan III staining and fecal trypsin activity examination by x-ray film digetion test were also undertaken daily. The results obtained were summarized as follows; 1. Serum amylase activities of the experimental group increased to peak on the third day and returned to the preoperative values on the eighth day. 2. Serum lipase activities of the experimental group increased to peak on the first day and returned to the preopertive values within six to eight days. 3. Serum glucose contents of the experimental group showed significant increse only on the first day. 4. Serum albumin contents of the experimental group decreased significantly during the experimental period. Whereas those of the control group significantly decreased only on the first day. 5. The experimental group showed marked leukocytosis, neutrophilia, and lymphopenia for the first 5 or 8 days. Whereas the control group showed only neutrophilia for the first 3 days. 6. The results of fecal fat droplet count showed some diagnostic value on the third and fourth day in only one experimental dog(No 1). No significant changes in the fecal trypsin activity were noticed in all dogs. 7. Histopathologically. all dogs of experimental group showed changes of pancreatitis. However the degree of the pancreatic lesion was not pararell to the degree of the serum amylase or lipase activity changes.

Pancreatic lipase-inhibitory activity of the rhizome of Rhei Rhizoma and its antihyperlipidemic activity were measured. Rhei Rhizoma inhibited pancreatic lipase with $IC_{50}$ value of 6.5 mg/ml (triolein as a substrate). Rhei Rhizoma significantly inhibited serum TG level in corn oil feeding-induced mice, and serum TG and cholesterol in Triton WR-1339-induced hyperlipidemic mice. However, Rhei Rhizoma did not show the hypolipidemic activity in high cholesterol diet-induced hyperlipidemic mice. When in vitro pancreatic lipase-inhibitory and in vivo antihyperlipidemic activities of Whangryunhaedoktang (WT) and Chunghyuldan (CD), which is consisted of ingredients of WT and Rhei Rhizoma, were measured, CD exhibited more potent inhibitory activities than WT. Therefore these results suggest that antihyperlipidemic activity of Rhei Rhizoma and CD may be more or less originated from the inhibition of pancreatic lipase.

Objective: This study was conducted to evaluate the effect of dietary energy and lipase supplementation on growth performance, nutrient digestibility, serum profiles, intestinal morphology, small intestinal digestive enzyme activities, biochemical index of intestinal development and noxious gas emission in weaning pigs. Methods: A total of 240 weaning pigs ([Yorkshire${\times}$Landrace]${\times}$Duroc) with an average body weight (BW) of $7.3{\pm}0.12kg$ were used in this 28-d experiment. Weaning pigs were randomly allocated to 4 dietary treatments in a $2{\times}2$ factorial arrangement with 2 levels of energy (net energy = 2,470 kcal/kg for low energy diet and 2,545 kcal/kg for basal diet) and 2 levels of lipase (0 and 1.5 U/g of lipase) according to BW and sex. There were 6 replications (pens) per treatment and 10 pigs per pen (5 barrows and 5 gilts). Results: Weaning pigs fed the low energy diet had lower (p<0.05) gain-to-feed ratio (G:F) throughout the experiment, apparent digestibility of dry matter, nitrogen, ether extract, and gross energy during d 0 to 14, average daily gain during d 15 to 28, lipase activity in duodenum and ileum and protein/DNA in jejunum (p<0.05), respectively. Lipase supplementation had no effect on growth performance but affected apparent nutrient digestibility (p<0.05) on d 14 and enhanced lipase activity in the duodenum and ileum and protease activity in duodenum and jejunum of pigs (p<0.05) fed the low energy diet. Lipase reduced serum low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG), $NH_3$ production (p<0.05) from the feces. Conclusion: The low energy diet decreased G:F throughout the experiment and nutrient digestibility during d 0 to 14 as well as lipase activity in duodenum and ileum. Lipase supplementation increased nutrient digestibility during d 0 to 14 and exerted beneficial effects on lipase activity in duodenum and ileum as well as protease activity in duodenum and jejunum, while reduced serum LDL-C, TG and fecal $NH_3$.

The purpose of this study was to investigate the effect of pretreatment with nicotinamide on the serum lipid composition and atherosclerotic index in streptozotocin ( STZ ) - induced diabetic rats. Nicotinamide pretreatment in STZ-induced diabetic rats inhibited the rise of serum glucose concentration. Serum total lipids and triglyceride levels in the STZ-induced diabetic rats were significantly higher than those in the control group. But in the group pretreated with nicotin-amide, triglyceride and lipid levels were significantly lower compared with those of STZ-induced diabetic rat group without nicotinamide. However, the serum phospholipid levels were not statistically different among treatment groups. In the STZ-induced diabetic group, the serum total cholesterol, VLDL, LDL-cholesterol levels and atherosclerotic index were higher and HDL-cholesterol level was lower compared to the control group. However, these changes were prevented by nicotinamide pretreatment. Pretreatment with nicotinamide significantly increased tile activities of serum lipase compared to the STZ-treated group. Aminotranferase (ALT, AST) activities were not significantly different in any of the groups.

This study was conducted to examine the effects of dietary xylooligosaccharides on lipoprotein lipase (LPL) activitiy in epididymal adipose tissue and lipid composition in serum of rats fed normal or high fat diet. Male Sprague-Dawley male rats weighing 100 $\pm$ 10 g were randomly divided into four groups, two normal diets and two high fat diets containing 1% cholesterol and 10% lard. Two normal diets were classified into a basal diet (normal group) and that with 10% xylooligosaccharide diet (NX group). The high fat diet groups were classified into a HF group without xylooligosaccharides diet and HFX group supplemented with 10% xylooligosacchride diet. Experimental diets were fed ad libitum to the rats for 4 weeks and then they were sacrificed. Body weight, epididymal weight and abdominal weight in HF group were hevier than the those of normal group, but HFX group was significantly reduced compared to HF group. Relative body weight to epididymal weight and relative body weight to abdominal weight in HF group were increased to 50%, 51%, respectively, compared to normal group, but HFX group was reduced 22%, 16%, respectively, compared to HF group. The levels of serum triglyceride, total cholesterol, LDL-cholesterol and atherogenic index in HFX groups were significantly lower than those of HF group, whereas HDL-cholesterol levels were significant increased. Triglyceride contents of epididymal adipose tissue in HF group was increased to 39%, compared to normal group, but HFX group was reduced to 15.8%, compared to HF group. Cholesterol contents of epididymal adipose tissue in HF group was increased 121%, compared to normal group, but HFX group was reduced to 26%, compared to HF group. The activity of LPL in epididymal adipose tissue was increased to 259% in HF group, compared to normal group and HFX group was reduced to 66%, compared to HF group. These result of this study suggested that improved lipid metabolism observed in rats fed xylooligosaccharides may be caused by an alteration of LPL activity in epididymal adipose tissue and lipid composition in serum.

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.

The purpose of this study was to investigate the effect of pretreatment with Saegchinyanghyoltang(SYT) on the serum lipid composition and atherosclerotic index in streptozotocin(STZ)-induced diabetic rats. SYT pretreatment in STZ-induced diabetic rats inhibited the rise of serum glucose concentration. Serum total lipids and triglyceride levels in the STZ -induced diabetic rats were significantly higher than those in the control group. But in the group pretreated with SYT, triglyceride and lipid levels were significantly lower compared with those of STZ -induced diabetic rat group without STZ. However, the serum phospholipid levels were not statistically different among treatment groups. In the STZ-induced diabetic group, the serum total cholesterol, VLDL-, LDL-cholesterol levels and atherosclerotic index Were higher and HDL-cholesterol level was lower compared to the control group. However, these changes were prevented by SYT pretreatment Pretreatment with SYT significantly increased the activities of serum lipase compared to the STZ-treated group.

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.

Covalent modification of a protein with polyethylene glycol (PEG) has become one of the most widely used and well established drug enhancement strategies in the biopharmaceutical industry. The general benefits enjoyed by PEGylation, such as prolonged serum half-lives or reduced immunogenicity in vivo, are well known. By now the PEGylation process has been performed with purified proteins, and it is required to recover the desired PEGylate by a multi-step purification process. The ultimate aim of our research is to develop an integrated process of PEGylation and in vitro refolding starting with inclusion body material. For this, we investigated the feasibility that a protein could be PEGylated under a denaturing condition and also the PEGylated proteins could be refolded correctly. Using lipase as a model protein, we found that it was PEGylated in the presence of 8M urea and that the PEG molecules covalently attached to lipase did not appear to hinder its refolding.
