Abstract: after pancreatic ressections due to chronic pancreatitis the remnant pancreas can lead to new outbreaks of pancreatitis in variable degrees of severity. after the resections by tumors or pancreatitis, the most common complications are the pancreatic fistulas with their resultant morbidity and mortality. in the pancreas transplantation the bowel or bladder drainage of the exocrine part of the graft, beyond the technical peculiarities of the execution, is not exempt of several complications. in order to avoid or reduce such consequences and trying to simplify the surgical technique, there have been used other approaches for the treatment of the pancreatic stump/graft: free drainage of the secretions with the duct left open, ductal ligature and duct occlusion with polymers. purpose: the proposal of our investigation was to study the clinical and laboratorial effects of the ductal ligature and the ductal left open in the endocrine and exocrine compounds of the rabbit pancreas. methods: one hundred and fifty operations were performed, divided in 3 groups: laparotomy/control (n=50), opened group (n=50) and ligated (n=50). the moments of observation were pre-operative, day 0 (operation's day) and post-operative (observation and sacrifice): 7 days, 14 days, 28 days, 90 days and 180 days. the parameters analysed were: general clinic state, activity and controls of body weight, water intake, food intake and measurements of blood and urinary glucose, serum-amylase and plasma insulin levels. results: all the groups had a similar clinical evolution: progressive body weight gain, water and food intake, as well as in good health conditions. conclusions: except for a significant serum-amylase elevation in the first 24-48 hours for the two ductal interference groups, there were no other blood glucose and insulin and urine-glucose variations in the 3 groups, in all observation moments.

Abstract: As ressec es pancreáticas seguidas de anastomoses acompanham-se de altas taxas de morbidade, que incluem: surtos de pancreatite e, principalmente, fístulas digestivas. Nos transplantes pancreáticos a drenagem da parte exócrina do enxerto para o intestino ou para a bexiga, além das peculiaridades técnicas, também n o é isenta de diversas complica es. Visando evitar ou atenuar tais conseqüências e simplificar a técnica cirúrgica, têm sido usadas outras abordagens para o tratamento ductal do coto/enxerto pancreático, tais como: drenagem livre de secre es para o perit nio, com o ducto pancreático aberto, ligadura ductal e oclus o do ducto com polímeros sintéticos. OBJETIVO: O presente estudo visa avaliar clínica e laboratorialmente as fun es endócrina e exócrina do pancreas de coelhos com o ducto aberto e ligado. MéTODOS: Foram realizadas 150 opera es, divididas em 3 grupos: N - manipula o/controle (n=50), A - grupo aberto (n=50), e L - ligado (n=50). Os momentos de observa o foram pré-operatório, dia 0 (dia da opera o) e pós-operatório (observa o e sacrifício): 7 dias, 14 dias, 28 dias, 90 dias e 180 dias. Os parametros analisados foram: estado geral, atividade, controles do peso corporal, ingest o hídrica, ingest o alimentar e dosagens da amilase sangüínea, glicemia, glicose urinária e insulina plasmática. RESULTADOS: Todos os grupos tiveram evolu o clínica similar, com bom estado geral, ganho ponderal progressivo e valores normais da ingest o hídrica e ingest o alimentar. Exceto uma significativa eleva o da amilase sangüínea nas primeiras 24-48h para os 2 grupos com interferência ductal, n o houve qualquer altera o dos níveis basais da glicemia, glicosúria e insulinemia entre os 3 grupos experimentais, em todos os momentos de observa o. CONCLUS O: à exce o da amilase sangüínea, cujos níveis basais foram significativamente elevados no 1o e 2o dias de pós-operatório, as duas modalidades técnicas de abordagem da secre o exócrina do pancreas, utilizadas em coelhos, n o determinaram quaisquer altera es clínicas, bem como dos níveis basais de glicose sangüínea, glicose urinária e insulina plasmática, durante 6 meses de seguimento.

Abstract: objective: the aim of this investigation was studying the influence of glucose metabolic control on diabetic nephropathy. the authors observed the effect of acarbose, insulin, and both drugs on the metabolic control and development of mesangial enlargement of kidney glomeruli in alloxan-diabetic rats. methods: five groups of wistar rats were used: normal rats (n), non-treated alloxan-diabetic rats (d), alloxan-diabetic rats treated with acarbose (ad), alloxan-diabetic rats treated with insulin (id), and alloxan-diabetic rats treated with insulin plus acarbose (iad). the following parameters were evaluated: body weight; water and food intake; diuresis; blood and urine glucose levels; and the kidney lesions: mesangial enlargement and tubule cell vacuolization. renal lesions were analysed using a semi-quantitative score 1, 3, 6, 9, and 12 months after diabetes induction. results: diabetic rats showed a marked increase of glycemia, urinary glucose levels, diuresis, water and food intake, and weight loss, while the treated diabetic rats showed significant decreased levels of these parameters. the most satisfactory metabolic control was that of diabetic rats treated with acarbose + insulin. there was a significant mesangial enlargement in diabetic rats compared to normal rats from the third up to the 12th month after diabetes induction, with a significant difference between the animals treated with acarbose + insulin and non-treated diabetic rats. a difference between the animals treated with acarbose or insulin alone and non-treated diabetics rats was not seen. conclusions: the authors discuss the results stressing the role of diabetic metabolic control in the prevention of diabetic nephropathy.
Considerations for Erythema Nodosum Leprosum, with Emphasis on Its Oral Manifestations  [PDF]

Advances in Infectious Diseases (AID) , 2013, DOI: 10.4236/aid.2013.31004
Abstract:

Leprosy is an infectious disease caused by Mycobacterium leprae, transmitted from person to person through contact among susceptible untreated patients. It presents a broad clinical spectrum which is related to the host’s ability to mount a specific immune response. The lesions caused by the proliferation of Mycobacterium leprae (M. leprae) were significantly reduced in recent years with the early detection of new cases. Because they are less evident and/or study, maxillofacial injuries and the oral mucosa may reveal important details about the transmissibility and immunopathogenesis of leprosy. This article was based on a literature to verify an interrelation between oral manifestations in virchowian patients and immuno-pathological factors. Association between the infection of oral mucosa and some pathological findings as well as the participation of the local immune response in protection against the disease are research topics still not fully exploited.

Abstract: we studied the effects of islet of langerhans transplantation (it) on the kidney lesions of rats with alloxan-induced diabetes. forty-five inbred male lewis rats were randomly assigned to 3 experimental groups: group gl included 15 non-diabetic control rats (nc), group git included 15 alloxan-induced diabetic rats (dc), and group iii included 15 alloxan-induced diabetic rats that received pancreatic islet transplantation prepared by nonenzymatic method from normal donor lewis rats and injected into the portal vein (it). each group was further divided into 3 subgroups of 5 rats which were sacrificed at 1, 3, and 6 months of follow-up, respectively. clinical and laboratorial parameters were recorded in the mentioned periods in the 3 experimental groups. for histology, the kidneys of all rats of each subgroup were studied and 50 glomeruli and 50 tubules of each kidney were analyzed using light microscopy by two different investigators in a double blind study. the results showed progressive glomerular basement membrane thickening (gbmt), mesangial enlargement (me), and bowman's capsule thickening (bct) in the 3 experimental groups throughout the follow-up. these alterations were significantly more severe in dc rats at 6 months when compared to nc rats (p < 0.01). however, the degree of gbmt, me, and bct observed in dc rats was not statistically different from it rats at 1, 3, and 6 months. in addition, armanni-ebstein lesions of the tubules (ae) and tubular lumen protein (pro) observed in dc rats were also observed in it rats all over the study. these lesions were never present in nc rats. we conclude that it did not prevent progression of kidney lesions in alloxan-induced diabetic rats within 6 months after transplantation.
