Effect of pancreatin on acute pancreatitis resulting from L-arginine administration in mice, a morpho-histopathological and biochemical study

Abstract Acute pancreatitis (AP) is a life-unpleasant situation with contradictory and inadequate treatments. In this regard, the present study evaluated the effect of the possible pretreatment of lipase-pancreatin on L-arginine-induced AP. Forty adult mice were selected and divided into five groups: I) control group, II and III) AP groups (i.p.) receiving L-arginine of 2×300 and 2×400 mg/100 g body weight (b.w.), IV) AP (2×300 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase), and V) AP (2×400 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase). All AP groups displayed a significant increase in serum levels of ALT, AST, TBARS, and TNF-alpha compared to the control group. Moreover, pancreatic tissue edema, inflammation, and vacuolization of acinar cells were significantly higher in the untreated L-arginine group compared to the control and pancreatin groups. Conversely, the diameter of pancreatic islets significantly declined after induction of pancreatitis compared with control and pancreatin groups. Pancreatin treatment can be used in pancreatic dysfunction, however, this medicine showed no protective effect against L-arginine-induced AP in the mouse model.

Total pancreatic necrosis after organophosphate intoxication / 医学前沿

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.

Degree of hydrolysis and peptide profile of whey proteins using pancreatin / Grau de hidrólise e perfil peptídico das proteínas do soro de leite utilizando a pancreatina

In the present study, we used pancreatin for hydrolyzing whey proteins and evaluated the degree of hydrolysis (DH) and peptide size distribution. The following methods were used for DH determination: formol titration, soluble protein content, ortho-phthalaldehyde (OPA), and freezing point. Peptide size distribution was conducted by size-exclusion high-performance liquid chromatography (HPLC). The DH varied from 3.26% to 36.41%, and the highest yield was obtained by the soluble protein content method (mean of 35.85%). Formol titration was considered the most suitable method for assessing the DH, because it showed a marked increase with reaction time (from 1h-17.20% to 2h-24.86%). Significant positive correlation of strong intensity was observed between the following methods: formol titration and OPA (r=0.9616; p=0.0090), formol titration and freezing point (r=0.8784; p=0.0493), and OPA and freezing point (r=0.9515; p=0.0127). The highest contents of di- and tri-peptides and free amino acids were 9.07% and 8.22%, respectively. A significant positive correlation of strong intensity was also observed between the degree of hydrolysis and the fraction of medium-sized peptides by the formol titration (r =?0.9274; p=0.0232) and OPA (r=?0.8977; p=0.0386) methods.

En este trabajo, se utilizó una pancreatina para hidrolizar las proteínas del suero de leche, evaluándose el grado de hidrólisis (GH) y la distribución de tamaño de los péptidos. Los métodos de valoración con formol, determinación de proteínas solubles, ortoftalaldehído (OPA) y disminución del punto de congelación se emplearon para evaluar el GH. La distribución del tamaño de los péptidos se realizó por cromatografía líquida de exclusión molecular. El GH varió de 3,26% a 36,41% y los mejores resultados se obtuvieron con el método de determinación de proteínas solubles (media de 35,85%). La valoración con formol se consideró el método más adecuado para evaluar el GH, en función de los significativos incrementos con el tiempo de reacción (de 17,20% a 24,86%). Se observó una correlación positiva y de fuerte intensidad entre los siguientes métodos: valoración con formol y OPA (r=0,9616, p=0,0090); valoración con formol y disminución del punto de congelación (r=0,8784, p=0,0493); OPA con la disminución del punto de congelación (r=0,9515, p=0,0127). Los contenidos más altos de di-tripéptidos y de aminoácidos libres fueron de 9,07% y 8,22%, respectivamente. Una correlación positiva y de fuerte intensidad se verificó entre la fracción de péptidos medios y el GH evaluado con los métodos de la valoración con formol (r=?0,9274, p=0,0232) y OPA (r=?0,8977, p=0,0386).

Os maiores teores de di-tripeptídeos e de aminoácidos livres foram de 9,07% e 8,22%, respectivamente. Correlação positiva e de forte intensidade foi verificada entre a fração de peptídeos médios e o GH avaliado pelos métodos da titulação com formol (r=?0,9274, p=0,0232) e OPA (r=?0,8977, p=0,0386).

Study on different factors affecting the bionic enzymatic hydrolysis of icariin / 药学学报

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%.

Perfil peptídico de hidrolisados enzimáticos do concentrado proteico do soro de leite, obtidos pela ação da pancreatina e da papaína / Peptide profile of enzymatic hydrolysates from whey protein concentrate obtained by action of pancreatin and papain

The aim of this study was to obtain enzymatic hydrolysates from whey protein concentrate with high oligopeptide, especially di- and tripeptides, and free amino acid contents, besides small amounts of large peptides. Different parameters were evaluated such as type of enzyme (pancreatin and papain), enzyme:substrate ratio (0.5:100, 1:100, 2:100 and 3:100), and the use of ultrafi ltration. The peptide profi les of the hydrolysates were characterized by using a fractionation method by size-exclusion HPLC followed by a rapid Corrected Fraction Area method for quantifying the components of the chromatographic fractions. The results showed that, in terms of number of analyzed samples, the pancreatin action was more advantageous than papain. However, the best peptide profile was obtained by papain, reaching 15.29% of di- and tripeptides, 47.83% of free amino acids and 25.73% of large peptides. The use of the smallest enzyme:substrate ratio (0.5:100) was beneficial in some cases for both enzymes, while the lack of ultrafiltration was favorable just for pancreatin.

El objetivo de este trabajo fue obtener hidrolizados enzimáticos a partir de concentrado proteico de suero lácteo con elevados contenidos de oligopéptidos, especialmente di y tri péptidos, y aminoácidos libres, además de reducida cantidad de grandes péptidos. Para eso fueron evaluados algunos parámetros como el tipo de enzima (pancreatina o papaína), la relación enzima:substrato (0,5:100, 1:100, 2:100 y 3:100)y el empleo de ultrafiltración. Para evaluar el perfil peptídico, los hidrolizados se sometieron a fraccionamiento en cromatografía líquida de alta eficiencia de exclusión molecular (SE-HPLC) y para la cuantificación de los componentes de las fracciones de la cromatografía fue utilizado el método del Área Corregida de la Fracción (ACF). Los resultados indican que el uso de pancreatina fue más ventajoso que el de papaína, así como la menor relación enzima:substrato (0,5:100). Por otro lado, el mejor perfil peptídico (15,29% de di y tripéptidos, 47,83% de aminoácidos libresy 25,73% de grandes péptidos) fue conseguido con el empleo de papaína. La menor relación enzima:substrato (0,5:100) fue favorable en algunos casos para las dos enzimas. La ausencia de ultrafiltración favoreció los hidrolizados producidos con pancreatina.

O presente trabalho teve como objetivo a obtenção de hidrolisados enzimáticos do concentrado proteico do soro de leite com elevado teor de oligopeptídeos, principalmente di- e tripeptídeos, e de aminoácidos livres, além de quantidade reduzida de grandes peptídeos. Para tal, foram avaliados diferentes parâmetros, como tipo de enzima (pancreatina e papaína), relação enzima:substrato (0,5:100, 1:100, 2:100 e 3:100) e o emprego da ultrafiltração. Caracterizou-se o perfil peptídico pelo fracionamento dos hidrolisados por cromatografia líquida de alta eficiência de exclusão molecular e, para a quantificação dos componentes das frações cromatográficas, empregou-se o método rápido da Área Corrigida da Fração. Os resultados obtidos indicaram que, em termos de número de casos analisados, a ação da pancreatina foi mais vantajosa do que a da papaína. Entretanto, o melhor perfil peptídico foi obtido pela açãoda papaína, dando origem a 15,29% de di- e tripeptídeos, 47,83% de aminoácidos livres e 25,73% de grandes peptídeos. A utilização da menor relação enzima:substrato (0,5:100) foi benéfica em alguns casos para ambas as enzimas, enquanto que a ausência da ultrafiltração mostrou-se favorável apenas para a pancreatina.

Clinical Outcomes of Pancreaticoduodenectomy in Children

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.

Novel agents for enzymatic and fungal hydrolysis of stevioside / Novos agentes para a hidrólise enzimática e fúngica do esteviosídeo

A comparative study on the potential of some biological agents to perform the hydrolysis of stevioside was carried out, aiming at establishing an alternative methodology to achieve the aglycon steviol or its rearranged derivative isosteviol, in high yields to be used in the preparation of novel bioactive compounds. Hydrolysis reactions were performed by using filamentous fungi (Aspergillus niger, Rhizopus stolonifer and Rhizopus arrhizus), a yeast (Saccharomyces cerevisiae) and enzymes (pancreatin and lipases PL250 and VFL 8000). Pancreatin showed the best hydrolytic activity, furnishing isosteviol at 93.9% of yield, at pH 4.0, using toluene as a co-solvent. Steviol was produced using both pancreatin at pH 7.0 (20.2% yield) and A. niger atpH 7 (20.8% yield).

Um estudo comparativo do potencial de alguns agentes biológicos capazes de hidrolisar o esteviosídeo foi realizado,objetivando-se estabelecer uma metodologia alternativa para a obtenção da aglicona esteviol ou seu produto de rearranjo, isoesteviol, em rendimentos elevados que permitam o uso destas agliconas para o preparo de novos compostos bioativos. As reações de hidrólise foram realizadas usando fungosfilamentosos (Aspergillus niger, Rhizopus stolonifer e Rhizopus arrhizus), uma levedura (Saccharomyces cerevisiae) e enzimas(pancreatina, lipase PL250 e lipase VFL 8000). A pancreatina mostrou a melhor atividade hidrolítica dentre os sistemastestados, fornecendo isoesteviol com rendimento de 93,9% em pH 4,0, usando tolueno como co-solvente. Esteviol foi produzido tanto usando pancreatina em pH 7,0 (20,2% derendimento) quanto usando A. niger em pH 7,0 (20,8% de rendimento).

Ação da pancreatina na obtenção de hidrolisados protéicos de soro de leite com elevado teor de oligopeptídeos / Action of pancreatin for obtaining whey protein hydrolysates with high oligopeptide contents

Vários hidrolisados enzimáticos de soro de leite foram preparados visando a elevação do teor de oligopeptídeos e a redução de custos para produção em larga escala. Para isso, empregou-se a pancreatina e alguns parâmetros hidrolíticos como o tempo de reação (5, 10 e 15h), a relação E:S (1:100, 2:100 e 4:100) e a concentração do substrato (10 e 15 por cento) foram testados. Os hidrolisados foram fracionados por cromatografia liquida de alta eficiência de exclusão molecular (SEHPLC) e, para a quantificação dos componentes das frações cromatográficas, empregou-se o método rápido da Área Corrigida da Fração. Para os parâmetros estudados, observou-se efeito benéfico sobre o perfil peptídico, sendo que o melhor resultado, associado, principalmente, ao maior teor de oligopeptídeos (49 por cento) e ao menor conteúdo de aminoácidos livres (22 por cento), foi obtido quando se empregou a concentração do substrato a 10 por cento, a relação E:S de 4:100 e o tempo de reação de 10h.

Several enzymatic hydrolysates of whey were prepared with the objective of increasing the oligopeptide content and reducing the cost of large scale production. Pancreatin was used and some hydrolytic parameters such as reaction time (5, 10 and 15h), enzyme:substrate ratio (E:S) (1:100, 2:100 and 4:100) and substrate concentration (10 and 15 percent) were tested. The hydrolysates were fractionated by size-exclusion-HPLC and the rapid corrected fraction area method was used for quantifying the chromatographic fractions. The beneficial effect on the peptide profile was observed in several cases, and it was mainly associated with higher oligopeptide (49 percent) and lower amino acid (22 percent) contents, which were obtained for a substrate concentration of 10 percent, E:S ratio of 4:100 and reaction time of 10h.

Imobilização da pancreatina em carvão ativado e em alumina para o preparo de hidrolisados de soro de leite / Immobilization of pancreatin in activated carbon and in alumina for preparing whey hydrolysates

Tendo como objetivo a redução de custos do processo de fabricação de hidrolisados protéicos, estudou-se neste trabalho a imobilização da pancreatina, por adsorção, em carvão ativado e em alumina. Para isso, foram testadas diferentes condições de imobilização (30, 60 e 90min a 25°C, e 12h a 5°C). Para verificar a taxa de imobilização, determinou-se indiretamente a enzima não adsorvida nos suportes. Ao se utilizar o carvão ativado, não foi observada diferença significativa entre as condições testadas, tendo-se obtido 100% de imobilização enzimática. Para a alumina, a melhor condição foi a de 90min, na qual se obteve 37% de imobilização. A medida do grau de exposição da fenilalanina, pela espectrofotometria derivada segunda, foi empregada para a determinação da estabilidade operacional da enzima, tendo sido mostrado que a imobilização em carvão ativado e em alumina permitiu a reutilização da pancreatina por até 5 vezes e 2 vezes, respectivamente.

Immobilization of pancreatin in activated carbon and in alumina was studied for producing protein hydrolysates, in order to reduce the process costs. Different immobilization conditions were tested (30, 60 and 90min at 25°C, and 12h at 5°C). For estimating the immobilization rate the amount of the non-adsorbed enzyme on the supports was indirectly determined. When activated carbon was used, no significant difference was observed among the tested conditions, obtaining 100% of enzymatic immobilization. In case of alumina, the best condition showed to be the 90min treatment which produced 37% of immobilization. The evaluation of the degree of exposition of phenylalanine, by second derivative spectrophotometry, was used for the determination of the enzyme operational stability, and showed that the immobilization in activated carbon and in alumina allowed the reusability of the pancreatin for 5 times and 2 times, respectively.

Avaliaçäo clínica de um complemento enzimático no tratamento da síndrome dispéptica / Clinical evaluation of an enzymatic supplement in the treatment of dyspeptic syndrome

A síndrome dispéptica se refere a um distúrbio que produz queixas abdominais superiores geralmente intermitentes, cujas causas näo podem ser determinadas pela avaliaçäo clínica. No seu tratamento têm sido empregados vários tipos de medicamentos, inclusive os complementos enzimáticos, os quais apresentam boa eficácia terapêutica. Em um estudo colaborativo, aberto, näo comparativo foi avaliada a resposta clínica de 143 pacientes portadores de sintomas dispépticos ao tratamento com um complemento enzimático à base de Aspergillusorizae, pancreatina e bile bovina - Combizym Composto -, na posologia de uma drágea três vezes ao dia por duas semanas. O diagnóstico mais prevalente foi o de dispepsia multifatorial, seguido de disfunçäo gastrointestinal e de disfunçäo biliar. Em 96 casos foi feito apenas um diagnóstico, enquanto que 24 pacientes apresentaram dois diagnósticos e os restantes três ou até quatro diagnósticos. Cento e oito pacientes foram submetidos a uma dieta, sendo 74 a uma dieta hipogordurosa, 24 a uma dieta hipogordurosa associada com fibras e os restantes 10 casos a uma dieta rica em fibras. A avaliaçäo da sintomatologia antes e após o tratamento demonstra uma excelente evoluçäo do quadro clínico. Os principais sintomas - distençäo abdominal, flatulência, eructaçäo, Náusea, vômitos e dor abdominal - desapareceram ou apresentaram melhora em mais de 93 porcento dos casos. Os sintomas constipaçäo intestinal e anorexia foram os que apresentaram evoluçäo menos acentuada, embora os resultados sejam considerados bons. A avaliaçäo final do tratamento pelos investigadores foi de 95,1 porcento como ótima e boa e pelos pacientes foi de 92,3 porcento. A tolerabilidade foi excelente, sendo que apenas 7 porcento dos casos apresentaram eventos adversos de leve intensidade, quase todos ligados à doença de base. Os resultados do presente estudo confirmam os obtidos por vários autores e demonstram que o complemento enzimático Combizym Composto atua eficazmente em todos os sintomas da síndrome dispéptica, com excelente tolerabilidade(au)

The influence of some medicinal plants with the digestive stimulation on the protease activity of pepsin and pancreatin

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.

Enzymatic determination of soluble and insoluble dietary fiber in rice and wheat bran

The information about dietary fiber presents controversies in many research areas such as in nomenclature, related illnesses, recommended quantities and terminology, mainly because of lack of analytical data. Different needs and interests for the dietary fiber composition of foods and forages have led to a proliferation of methods for its analysis. This research, a further adaptation of the enzymatic method of Asp et al. (1983) for its appplication is proposed for rice and wheat bran, byproducts of agroindustries in the southern region of Rio Grande do Sul (Brazil). The inclusion of Amyloglucosidase in the proposed methodology contributed to the decrease in the content of residual starch at the end of the experiment, like Prosky et al (1992). To increase the efficiency of the enzyme system inthis type of samples, other changes were made with respect to incubation time and proteolytic enzyme concentration. In the final adaptation, a decrease of 51.33 per cent of the starch content was observed in rice bran (RB) and of 52.93 per cent in wheat bran (WB). This decrease was also verified in the model system (MS) (52.08 per cent), which demonstrates the adequacy of the proposed adaptation. With respect to the residual protein, it was verified that the measures adopted provoked a reduction of 42.15 per cent (RB), 52.19 per cent (WB) and 42.11 per cent (MS) as compared to the original method. Then the proposed conditions has been shown to be efficient in decreasing the level of interference (indigestible starch and protein) in the quantification of dietary fiber in rice and wheat bran.

Lesäo hepatica na pancreatite aguda experimental: influencia da reduçäo da reserva enzimatica do pancreas / Evaluation of hepatic lesion of experimental acute pancreatitis: influence of pancreatic enzyme reduction

A pancreatite aguda (PA) produz alteracoes morfologicas e funcionais no figado. A administraçäo de doses baixas de ceruleina diminui o conteudo enzimatico do pancreas. O objetivo do presente estudo foi estudar o efeito da reduçäo do conteudo enzimatico do pancreas na funçäo mitocondrial hepatica. Ratos machos Wistar foram submetidos a PA atraves de injeçäo retrograda intraductal de taurocolato de sodio a 5 por cento com e sem infusäo de ceruleina (0,133 ug/Kg/h) durante tres horas : Grupo I (GI): sem reducao enzimatica do pancreas, com induçäo de PA, GRUPO II (GII): com reduçäo enzimática do pancreas, com induçäo de PA, GRUPO III (GIII): com reduçäo enzimatica do pancreas, sem induçäo de PA, GRUPO IV (GIV): sem reduçäo enzimatica do pancreas, sem induçäo de PA (Controle). Após duas horas da inducao da PA os animais foram sacrificados e os figados retirados para avaliaçäo da funçäo mitocondrial hepatica, determinada polarograficamente com eletrodo de Clark, medindo-se o consumo de oxigenio na ausência de ADP (S4-Basal) e na presença de ADP (S-3 Ativado), utilizando-se succinato de potassio como substrato. Os conteudos de tripsina, amilase e proteinas totais no liquido ascitico foram determinados. Após duas horas da induçäo da PA observamos aumento significativo no estado 4 da respiraçäo (41 por cento) e diminuiçäo do RCR e da relaçäo ADP/O nos animais do GI (PA sem ceruleina) quando comparados com os animais do GII (PA com ceruleina) (p<0,05). O conteudo de amilase (A) e tripsina (T) no liquido ascitico mostraram-se diminuidos nos animais do GII (A=80 +- 10 U/ml, T= 9,75 +- 1,25 U/ml), quando comparados com os animais do GI que nao receberam ceruleina ( A= 231 +- 24 U/ml, T = 40,32 +- 5,19 U/ml) (p<0,001). Infusäo somente de ceruleina (GIII) näo alterou a funçäo mitocondrial hepatica. Estes achados sugerem que a reduçäo do conteudo enzimatico do pancreas através de infusäo de ceruleina atenua a disfunçäo mitocondrial hepatica na PA experimental evidenciada por desacoplamento da oxigenaçäo fosforilativa
