Purpose: Colitis is a widespread inflammatory bowel disease with heterogeneous etiology (genetic and immunological). It is treated with drugs such as steroidal and non-steroidal anti-inflammatory that, in the long term, can cause side effects. For this reason, the exploitation of natural resources to combat this type of disease is the concern of researchers. The purpose of our study was to evaluate the anti-colitis (anti-inflammatory) effect of β-Chitosane induced in albino mice by acetic acid (5%). Methods: Mices were separated into six groups: the witness (untreated and not ulcerated), negative control group (ulcerated and untreated), the positive control ulcerated and treated with the Dexaméthasone® (1 mg/kg), and test groups ulcerated and treated with different doses of β-Chitosane (0.5 g/ kg; 0.75 g/ kg and 1 g/ kg) for the entire treatment estimated to six-days. β-Chitosane efficacy was evaluated by macroscopic and microscopic scores. Results: The clinical scores showed that β-Chitosane with a dose of 1 g/kg for the entire treatment significantly reduced the damage caused by acetic acid with a score of (3.41 ± 1.45) compared to those of the positive control which reduced less the inflammation (6.26 ± 1.23). The histological study of the colons was able to validate the effect of β-Chitosane by decreasing neutrophil infiltration and ulceration in the colon as well as by structural recovery of the mucosa. Conclusion: These results provide evidence that β-Chitosane has a protective effect against ulcerative colitis that may be due to its antioxidant, anti infectious, anti-inflammatory and healing activities.

Objective: The aim of this work was to study the biochemical characteristics of coconut milk and its antigenic effect on the Balb/c mice immunized with α-lactalbumin protein, as well as its consequences on the structure of the intestinal epithelium.Methods: To achieve the objective of the study, an electrophoresis was realised on a polyacrylamide gel to determine various proteins contained in coconut milk. In addition, Lowry’s method was used to determine the amount of proteins in the formula. The antigenicity of coconut milk in sera was also studied using the Enzyme-Linked Immunosorbent Assay (ELISA) method. For the histological study, 21 w-old mice Balb/c were used and distributed in three groups of 7 mice each. Group 1, received a standard feed with no treatment (Negative control), group 2 and 3 received respectively a standard feed (Positive control) and coconut milk for a period of 28 d after being immunized with α- lactalbumin.Results: Analysis of the data revealed that the rate of proteins of cow’s milk is higher than that of the coconut milk ( p0.01). However, after carrying out the electrophoresis analysis, the coconut milk showed the absence of intact proteins. The anti α-Lactalbumin IgG titers significantly increased in positive control groups that received coconut milk (p<0.0001). Moreover, there was an increase of the intestinal villi height of mice fed with coconut milk, in the structure level of their intestinal epithelium compared to the negative control group.Conclusion: The findings of the study provide the evidence that coconut milk is a possible alternative to the cow’s milk formula in case of allergy.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

Abstract The study aimed to investigate the possible anti-inflammatory activity of larch sawdust as feed supplement in lactating sows’ diet and its possible effect on the prevalence of Postpartum Dysgalactia Syndrome under field conditions. In a Greek farrow-to-finish pig farm, fifteen sows were randomly and equally allocated to a negative control group (NC group), a positive control group (PC group), and a treatment group (LT group). The animals of the first two groups received 99% basic diet and 1% corn starch, while LT group animals received 99% basic diet and 1% larch sawdust. The whole trial period lasted 35 days (7 days prior to farrow – day of weaning). At parturition day, animals of the PC group received 2 ml of an anti-inflammatory drug intramuscularly (meloxicam, Metacam®, Boehringer Ingelheim Vetmedica), while the animals of both other groups, received 2 ml of normal saline. Results showed insignificant differences among experimental groups for parameters such as post-partum rectal temperature and piglets performance. On the contrary, a significant increase of mean milk lactation index was observed in LT and PC groups on the 4th day of lactation period, when compared with NC group (p=0.014). Additionally, mean IL-6 concentrations in blood in the LT group showed a tendency for reduction when compared with those found in NC, and insignificant difference (p>0.05) when compared with those observed in PC group 24 hours postpartum. Moreover, the respective TNFα mean level in the LT group at 24 and 72 hours after parturition was similar to that found in PC group, respectively) and significantly lower than that determined in the NC group (p=0.003, p=0.024. The results suggest a possible anti-inflammatory effect of larch sawdust in sows.

Spirulinasp.is an alga that has antioxidant and anti-inflammatory potential.Phycocyanin contained in Spirulina platensis can reduce tumor necrosis factor-? levels, neutrophils, and M2 macrophages in inflammation. This research aims to investigate the anti-inflammatory activity of S. platensisin a mice wound model. Thirty-two male Wistar rats were incised and divided into 4 groups. The first therapeutic group (X1) received S. platensisextract at a dose of 500 mg/kgBW/day, and the second therapeutic group received S. platensisextract at a dose of 750 mg/kgBW/day. The negative control group (C1) received a saline solution and the positive control group (C2) received diclofenac sodium 20mg/kgBW/day. Serum TNF-? levels examined by the Enzyme-Linked Immunosorbent Assaymethod. Neutrophils and M2 macrophages were calculated by tissue biopsy and hematoxylin-eosin (HE) staining. Data analysis was performed with ANOVA test and LSD Post-Hoc Test. The average levels of serum TNF-? on the 14-day were 394.50; 180.33; 2,980.33; and 607.42 pg/ml for X1, X2, C1 and C2, respectively. The average neutrophils number on the 14-day were 8.00; 6.83; 14.67; and 11.17 for X1, X2, C1 and C2, respectively. The average macrophage number in the 14-day was 15.50; 19.17; 6.33; and 11.17 for X1, X2, C1 and C2, respectively. We found significant differences between TNF-? levels, the number of neutrophils, and the number of M2 macrophages. The administration of S. platensisextract at a dose of 750 mg/ kgBW/day reduces serum TNF-? levels, neutrophil count, and increases M2 macrophages in skin incisional mice model.

The focus of our study is to compare the anti-inflammatory effect of extracts prepared from Algerian mollusk called Helix ,on induced lung inflammation in rats: aqueous AE, HE and organic OE extracts. Animals were classified into six groups: control group T was instilled with NaCl (0.9%) in the trachea, negative control group was instilled with in trachea (5mg//Kg), positive control group was instilled with and treated with an anti-inflammatory drug, groups SAE, SHE and SOE were instilled with and treated with aqueous, and organic extracts respectively (4mg//Kg). 24h after instillation, we sacrificed animals, blood samples and fluid lavage (BALF) were collected. Lungs were for investigation. We measured activity (MPO) in BALF. Results showed induces a massive in lungs. HE and OE decreased leukocyte count in BALF and blood. AE increased leukocyte count in blood and decreased it in BALF. The three extracts decreased MPO activity in BALF, reduced number of inflammatory cells in the and protected lung from beads injuries. Both AE and HE reduced edema in lung. We conclude that treatment with Helix had an anti-inflammatory effect on inflammation.
