Abstract
Background:
Hypovolemic shock is a common disease in polytrauma patients and may develop
ischemia in various organs, increasing morbidity and mortality. The bowel is
usually most affected by this condition.
Aim:
To evaluate the effects of copaiba oil on the intestinal mucosa’s injury of
rats submitted to hypovolemic shock.
Method:
Fifteen rats were divided into three groups: sham - simulated surgery;
ischemia - animals submitted to hypovolemic shock; and copaiba - animals
submitted to hypovolemic shock previously treated with copaiba oil. Mean
blood pressure, arterial blood gas after shock induction, degree of
intestinal lesion and villus length were evaluated.
Results:
The sham presented the lowest values of lactate and PaCO2 and the
highest values of mean arterial pressure, pH and bicarbonate in relation to
the other groups. The degree of mesenteric lesion was zero in the sham
group; 3.00±1.00 in the ischemia group; and 3.00±0.71 in the copaiba group.
The villus length was 173.60±8.42 in the sham, 142.77±8.33 in the ischemia
and 143.01±9.57 in the copaiba group. There was a significant difference
between the sham and the other groups (p<0.05); however, there not
significant difference between groups Ischemia and copaiba.
Conclusion:
Administration of copaiba oil did not reduce the intestinal mucosa lesion of
rats after hypovolemic shock.

Abstract
Background The oil-resin of Eperua oleifera Ducke has been used in popular medicine similarly to the copaiba oil (Copaifera spp.). Objective This study aimed to investigate the effects of the acid fraction of E. oleifera oil-resin (AFEOR) on cell proliferation, collagen production in human fibroblasts, inhibition of metalloproteinases, and cytotoxicity against tumor cell lines. Materials and Methods Acid fraction of E. oleifera was fractionated in the ion exchange column chromatography. Cytotoxicity and genotoxicity were evaluated by Alamar Blue® and Cometa assay. The inhibition of metalloproteinases was performed by zymography and Western blotting. Results The predominant acidic diterpenes in the AFEOR were copalic and hardwickiic acids. AFEOR caused morphology alteration and decrease of proliferation at concentrations higher than 5 μg/mL. It also caused significant collagen proliferation in fibroblasts. It showed cytotoxicity against tumoral and nontumoral cell lines, with IC50 values ranging from 13 to 50 μg/mL, and a hemolytic activity with an IC50 value of 38.29 μg/mL. AFEOR inhibited collagenase activity, with an IC50 value of 46.64 μg/mL, and matrix metalloproteinase-2 (MMP)-2 and MMP-9 in HaCaT cells or MMP-1 expression in MRC-5 cells. AFEOR induced genotoxicity in MRC-5 cells with a DNA damage index between 40% and 60% when compared to the negative controls (0%-20%). Conclusion For the first time, biological activities from oil-resin E. oleifera demonstrated ratifying somehow its popular use. SUMMARY Analysis of crude oil-resin and fractionation of diterpenic fraction was performance using selective ion-exchange column chromatographyCytotoxicity analysis and morphology were performed with different cell linesCollagen production in human fibroblasts, inhibition of metalloproteinases were demonstrated by zymography and Western blotting.

Abstract
Copaiba oil comes from an Amazonian tree and has been used as an alternative medicine in Brazil. However, it has not been investigated yet in the treatment of cardiovascular diseases. This study was designed to test whether copaiba oil or nanocapsules containing this oil could modulate monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH). Male Wistar rats (170 ± 20 g) received oil or nanocapsules containing this oil (400 mg/kg) by gavage daily for 1 week. At the end of this period, a single injection of MCT (60 mg/kg i.p.) was administered and measurements were performed after 3 weeks. The animals were divided into 6 groups: control, copaiba oil, nanocapsules with copaiba oil, MCT, oil + MCT, and nanocapsules + MCT. Afterward, echocardiographic assessments were performed, and rats were killed to collect hearts for morphometry and oxidative stress. MCT promoted a significant increase in pulmonary vascular resistance, right ventricle (RV) hypertrophy, and RV oxidative stress. Both oil and copaiba nanocapsules significantly reduced RV hypertrophy and oxidative stress. Pulmonary vascular resistance was reduced by copaiba oil in natura but not by nanocapsules. In conclusion, copaiba oil seems to offer protection against MCT-induced PAH. Our preliminary results suggest that copaiba oil may be an important adjuvant treatment for PAH.

Abstract
Copaifera oleoresin is one of the most used natural products in popular medicine all over the world. Among other effects (i.e., anti-inflammatory, antinociceptive, microbicidal) one of the most well-known is its wound healing capacity. However, the mechanism by which the oleoresin presents its effect is still not clear. In this study, our aim was to evaluate the wound healing capacity of oleoresin obtained from Copaifera paupera, its mechanism of action and identify its major components. For these purposes, diabetic Swiss Webster mice were topically treated with oleoresin (100, 150 or 200 mg/kg) for 14 consecutive days after an excision was performed in the back of the mice. Cytokines, wound retraction and histological evaluation were conducted at 3, 7 and 10 days (for cytokines); 0, 3, 7, 10 and 14 days (for wound retraction); and 7 and 14 days (for histological evaluation). Our data indicate that oleoresin significantly reduced production of MCP-1 and TNF-α at days 7 and 10 post-excision and increased IL-10 production at both days. All treatments demonstrated an effect similar or higher to that in collagenase-treated mice. Histological evaluations demonstrated that higher dose treatment resulted in better resolution and closure of the wound and higher levels of collagen deposition and indexes of re-epithelialization even when compared with the collagenase-treated group. The treatment with oleoresin from Copaifera paupera demonstrated that it is even better than an ointment routinely used for improvement of wound healing, suggesting this oleoresin as an option for use in diabetic patients.

Abstract
How the distance of sutures from the edge of tissue and the horizontal distance between stitches affect the mechanical strength of anastomosis is investigated. In this study, 180 bovine intestines were used to investigate the optimum pattern in 18 groups by considering a 4, 6, and 8 mm horizontal distance between stitches, and a 3, 5, and 7 mm distance from the edge of tissue with 3-0 Silk and 3-0 PDS sutures to maximize the strength of anastomosis (10 specimens in each group). Also, 80 specimens were used to investigate the maximum effective distance of sutures from the edge of tissue in eight groups of: 3, 5, 7, and 10 mm distance from the edge, with the same type of sutures. Tensile tests with an elongation rate of 5 mm/min were performed for all the groups. Based on the results, the pattern of 7-6 (distance from the edge-distance between stitches) for both 3-0 Silk and 3-0 PDS, 5-6 and 7-4 for 3-0 Silk, and 5-6 and 7-4 for 3-0 PDS can be considered as the best options among 18 different combinations. It was also found that increasing the distance from the edge from 7 mm to 10 mm does not cause a significant difference in mechanical strength. Results can help surgeons to improve the intestinal anastomosis and employ it as an input for automatic suturing devices.

Abstract
The goal of our study was to evaluate the effect of kaurenoic acid, obtained from copaiba oil resin, in gastric cancer (GC) and a normal mucosa of stomach (MNP01) cell lines. The compound was tested at concentrations of 2.5, 5, 10, 30 and 60μg/mL. Comet and micronucleus assays were used to access its potential genotoxicity in vitro. Moreover, we evaluated the effect of kaurenoic acid in cell cycle progression and in the transcription of genes involved in the control of the cell cycle: MYC, CCND1, BCL2, CASP3, ATM, CHK2 and TP53. Kaurenoic acid induced an increase on cell DNA damage or micronucleus frequencies on GC cell lines in a dose-dependent manner. The GC and MNP01 cell lines entering DNA synthesis and mitosis decreased significantly with kaurenoic acid treatment, and had an increased growth phase compared with non-treated cells. The treatment induced apoptosis (or necrosis) even at a concentration of 2.5μg/mL in relation to non-treated cells. GC cell lines presented reduced MYC, CCND1, BCL2 and CASP3 transcription while ATM, CHK2 and TP53 increased in transcription in relation to non-treated cells, especially at a concentration above 10μg/mL. The gene transcription in the MNP01 (non-treated non-cancer cell line) was designated as a calibrator for all the GC cell lines. In conclusion, our results showed that kaurenoic acid obtained from Copaifera induces DNA damage and increases the micronuclei frequency in a dose-dependent manner in GC cells, with a significant genotoxicity observed above the concentration of 5μg/mL. Moreover, this compound seems to be able to induce cell cycle arrest and apoptosis in GC cells.

Abstract
ABSTRACT Objectives: to evaluate, histologically and macroscopically, the influence of Copaifera multijuga (Copaíba) oil-resin on the healing process of cutaneous wounds, comparing it with nitrofurazone. Methods: we divided 36 rats into three groups of 12 animals, according to the treatment to be administered. Group SL (control) received saline on the lesion; the Group OIL received topical treatment with Copaíba oil; and the Group NITRO was treated with Nitrofurazone. We inflicted a circular wound of 8mm in diameter on the back of each animal. We subdivided each of the three groups of 12 animals into three subgroups, according to treatment time and euthanasia (7, 14 and 21 days). All animals received the proposed treatment daily. We photographed the lesions for area measurement, as well as for evaluation of macroscopic aspects. We resected and stained the scars to quantify and qualify elastic fibers, collagen, degree of epithelization, neovascularization and inflammation. Results: although the saline solution provided a faster wound closure in its initial phase, after 14 days the wound size of the three groups tested was the same. Levels of inflammation and neovascularization were similar in all three groups. The amount of collagen and elastic fibers was higher in the Nitrofurazone and Copaíba oil groups. Conclusion: in male Wistar rats, Copaifera multijuga oil-resin positively influences the healing process, but it is less effective than nitrofurazone in healing by secondary intention.

Abstract
PURPOSE Aim was to formulate oil-in-water (O/W) microemulsion with a high volume ratio of complex natural oil, i.e. copaiba oil and low surfactant content. The strategy of formulation was based on (i) the selection of surfactants based on predictive calculations of chemical compatibility between their hydrophobic moiety and oil components and (ii) matching the HLB of the surfactants with the required HLB of the oil. METHOD Solubility parameters of the hydrophobic moiety of the surfactants and of the main components found in the oil were calculated and compared. In turn, required HLB of oils were calculated. Selection of surfactants was achieved matching their solubility parameters with those of oil components. Blends of surfactants were prepared with HLB matching the required HLB of the oils. Oil:water mixtures (15:85 and 25:75) were the titrated with surfactant blends until a microemulsion was formed. RESULTS Two surfactant blends were identified from the predictive calculation approach. Microemulsions containing up to 19.6% and 13.7% of selected surfactant blends were obtained. CONCLUSION O/W microemulsions with a high volume fraction of complex natural oil and a reasonable surfactant concentration were formulated. These microemulsions can be proposed as delivery systems for the oral administration of poorly soluble drugs.

Abstract
PURPOSE To compare ileal anastomoses in the immediate postoperative healing period after meloxicam use. METHODS Forty two male Wistar rats were randomly divided into two groups of 21, COX and control group. To COX meloxicam in combination with morphine was given in 3 days period. Control group received only morphine during the same period. Each group was divided into three sub-groups of 7, which were euthanized at 5, 10, and 21 days postoperatively. Comparison was based in histological evaluation of collagen type I and III using sirius red, immunohistochemical through vascular endothelial growth factor and matrix metalloproteinase-9. RESULTS Healing process in scheduled periods did not show significant differences (p>0.05) between the COX and control groups during any of the periods. CONCLUSION The use of meloxicam in the postoperative period following ileal anastomosis did not affect healing.

Abstract
In this research, intestinal anastomosis was compared in hand and automatic suturing. This work is based on two different experiments: The first one is the tensile test with the aim of finding the maximum breaking strength with the elongation rate of 5[Formula: see text]mm/min; and the second one is the fatigue test with a frequency of 0.2[Formula: see text]Hz and the amplitude of 16, 24 and 32[Formula: see text]mm of stretch in each phase to discover the total number of cycles to failure. For this purpose, 42 fresh bovine intestines were used; 21 specimens for the tensile and 21 for the fatigue test. These two tests were compared by two hand sewing techniques: simple continuous and ford interlocking stitches, and one automatic technique, i.e., the lock stitches. Seven samples were examined for each particular technique. The results of the tensile test indicated that the breaking strength of automatic sutured specimens is significantly greater than those of hand sutured specimens ([Formula: see text]). That might be due to the regularity, as the suturing lines by machines are more regular than suturing by hand. In addition, results showed that automatic sutured specimens failed in greater number of cycles than hand sutured specimens in the fatigue test ([Formula: see text]).

Abstract
Copaiba oil-resin, extracted from the trunk of Copaifera, and traditionally used in folk medicine in the treatment of various disorders, has been shown to be an effective antiinflamatory, antitumor, antitetanus, antiseptic and anti-blenorrhagea agent. As, there are few studies evaluating its genotoxicity, this aspect of the commercial oil-resin, and its volatile and resinous fractions, were evaluated in mice by comet assay and micronucleus (MN) test. A single dose of oil resin, volatile or resin fractions (500; 1,000 or 2,000 mg/kg b.w.) was administered by gavage. The chemical compositions of Copaiba oil resin and its fractions was analyzed by gas chromatography. According to comet assaying, treatment with either one did not increase DNA damage, and as to MN testing, there was no alteration in the incidence of micronucleated polychromatic erythrocytes. Chromatographic analysis of the oil-resin itself revealed sesquiterpenes, diterpenic carboxylic acid methyl esters and high levels of β-caryophyllene. Thus, it can be assumed that the oil resin and volatile and resinous fractions from the commercial product are not genotoxic or mutagenic.

Abstract
Copaiba oleoresins are exuded from the trunks of trees of the Copaifera species (Leguminosae-Caesalpinoideae). This oleoresin is a solution of diterpenoids, especially, mono- and di-acids, solubilized by sesquiterpene hydrocarbons. The sesquiterpenes and diterpenes (labdane, clerodane and kaurane skeletons) are different for each Copaifera species and have been linked to several reported biological activities, ranging from anti-tumoral to embriotoxic effects. This review presents all the substances already described in this oleoresin, together with structures and activities of its main terpenoids.
