Background: Lipomatous pseudohypertrophy of the pancreas, pancreatic lipomatosis, pancreatic steatosis, non-alcoholic fatty pancreatic disease, or fatty pancreas is an extremely rare disease, characterized by the organ enlargement and a localized or diffuse replacement of pancreatic acinar cells by mature adipose tissue, preserving the pancreatic ductal system and islets of Langerhans.
Aims: To report a rare case of lipomatous pseudohypertrophy of the pancreas in a symptomatic patient and the surgical treatment employed.
Methods: A 24-year-old male patient with weight loss (10 kilograms in 8 months), hyperglycemia, severe and recurrent acute abdominal pain, epigastric discomfort associated with nausea, vomiting, and jaundice for 40 days.
Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable.
Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red wine consumption.
Methods: 60 ApoE knockout mice were divided into three groups of 20: Wine Group (WG), Ethanol Group (EG) and Water Group (WAG).
Purpose: To evaluate macro and microscopically, changes following the use of the aqueous extract of babassu (Orbignya phalerata) in the lung parenchyma and pleura of rats.
Methods: Sixty adult male rats with average weight of 350 g, were randomized into two groups of 30 animals (experimental and control) further divided into sub-groups of 10 to be sacrificed at 48 h, 72 h and 21 days. The substance was injected into the right pleura of the animals.
Use of raw Euphorbia tirucalli extract for inhibition of ascitic Ehrlich tumor.
Rev Col Bras Cir
February 2016
Objective: to evaluate the effect of the Euphorbia tirucalli hydroalcoholic extract (ETHE) on the development of Ehrlich Tumor, in its ascitic form.
Methods: we intraperitoneally inoculated 15 Swiss mice with 10.44 x 107 cells of Ehrlich Tumor and divided them in two groups one day after: ETHE Group (eight mice), treated with a dosage of 125 mg/kg/day of EHTE for five days; and Control Group (seven mice), treated only with 0.
Purpose: To analyze microscopically the effects of different concentrations of oxygen in the lungs of rats.
Methods: There were 20 rats distributed in three experimental groups (concentration of oxygen to 40%, 70% and 100%) and a control group. The animals were exposed to the oxygen in a chamber of acrylic during three days and after exposition, the animals were submitted to median thoracotomia to remove the lungs.
Background: The use of plants in the prevention and treatment of disease is age-old practice. The aveloz (Euphorbia tirucalli) is a plant native of Africa and has been associated with antimicrobial, antiulcers, anticarcinogenic, antiviral, healing, anti-helminthic, antisiphilitic effects.
Aim: To analyze the effect of the crude extract of Euphorbia tirucalli L.
Evaluation of the use of raw extract of Euphorbia tirucalli L. in the healing process of skin wounds in mice.

October 2013
Purpose: To evaluate the effects of crude extract of Euphorbia tirucalli in cutaneous wound healing.
Methods: A total of 20 Swiss mice were randomly divided into two groups, aveloz (GA) and control (CG), and each group was further divided into two subgroups based on the deaths scheduled for the 7th and 14th days after surgery. The animals underwent a resection of cutaneous fragment with 1cm in diameter on the dorsum; the GA was applied in each animal on the subsequent days, 0.
[Influence of Schinus terebinthifolius Raddi (aroeira) and Carapa guianensis Aublet (andiroba) in the healing process of gastrorraphies].

June 2013
Background: The gastrorraphy isolated or associated with the use of biological adhesives formed throughout the history of surgery the usual way to promote healing in gastric lesions; however, the use of herbal medicine has been increasingly employed to help the wound healing.
Aim: To evaluate the wound healing caused in the stomach of rats using extract of Schinus terebinthifolius Raddi and Carapa guianensis Aublet oil.
Methods: Ninety rats, adult males were divided into three groups: aroeira, andiroba and control group, which were subdivided into three subgroups of five animals according to the time of the deaths (seven, 14 and 21 days).
Background: Gastrorraphy, isolated or associated with the use of biological adhesives, was throughout the history of surgery the usual way to promote healing in gastric lesions and the use of herbal medicine has been increasingly more employed.
Aim: To evaluate the wound healing in the stomach of rats with the use of the hydroalcoholic extract of Schinus terebinthifolius Raddi (aroeira).
Methods: Sixty rats, adult males, were divided into two groups: aroeira group and control group.
Purpose: To evaluate the healing process of rat traumatic liver lesion corrected with the use of 2-octyl cyanoacrylate adhesive, compared to the use of biologically absorbable chromed catgut thread suture.
Methods: Thirty mail adult rats were divided into two groups (15 per group) according to the used method for liver lesion correction as follows: adhesive group (AG), and catgut group (CG); each group being divided into three subsets of five animals (7th, 14th, and 21st day), respectively, according to post-surgery evaluation. All animals were submitted to homogeneous lesion applying synthetic bonding to AG and using chromed catgut suture to CG for lesion correction.
