This study was done to evaluate exposure to inhalation of formalin as a disinfectant for poultry house on hematological, biochemical parameters and histopathological examination in the broiler. The used (24) chicken divided into two groups, every group included (12) chicken. The first group (control) and second group exposure to formalin by inhalation for 2 weeks. Blood samples were collected at end of each week for analyzed some hematological such as (PCV, Hb, RBCs, total WBC counts and differential WBC count) and biochemical parameters such as (total protein, albumin, globulin and bilirubin) at the end of each week after 1wk scarified of half number of broiler and remove organs such as (lung, heart, and liver) for histopathological examination and end of 2wk scarified the reminder number of broiler. In our study, the hematological changes revealed significant decreases in PCV, Hb, RBCs, and WBC count after 1wk and 2wk compared with the control group. The total protein, albumin, and globulin showed significant decreases while bilirubin showing significant increasing after 1wk and 2wk of treated group compared with the control group. The differential WBC count showed significant increasing into neutrophils, and monocytes after 1wk while there was significant increasing into eosinophils, basophils, and neutrophils after 2wk compared with the control group. There was significantly decreasing into lymphocytes eosinophils and basophils after 1wk of treated groups but after 2wk the monocytes and lymphocytes that showed significant decreasing. The histopathological examination of lung in treated group after 1wk revealed highly changes that represent by congestion of blood vessels, hemorrhages with thickening of blood vessels walls, thickening into alveolar walls, alveoli filled with erythrocytes and fibrin, hemosiderosis, and hyperplasia of alveolar cells into treated group compared with control group, while after 2wk the changes was emphysema (destruction of alveolar walls) only. The heart revealed congestion of blood vessels after 2weeks. The liver revealed more changes that represented by congestion of central veins and necrosis in the hepatocytes, fibrosis, and hyperplasia into the portal area of the liver tissues compared with control group. Changes into liver after 2wk of treated group showed acute inflammation, congestion of blood vessels, hemorrhage and degeneration of hepatocytes with necrosis into some areas. After 1wk the heart show slightly changes includes congestion of blood vessels and slightly infiltration of inflammatory cells and hemorrhage compared with control group, but after 2wk the heart shows more infiltration of inflammatory cells with fibrosis of treated group compared with control group.

AbstractFailure in the treatment of P. aeruginosa, due to its broad spectrum of resistance, has been associated with increased patient mortality. One alternative approach for infection control is quorum quenching which was found to decrease virulence of such pathogen. In this study, the efficiency of a recombinant Ahl-1 lactonase formulated as a hydrogel was investigated to control the infection of multidrug resistant (MDR) P. aeruginosa infected burn using a murine model. The recombinant N-acylhomoserine lactonase (Ahl-1) was formulated as a hydrogel. To test its ability to control the infection of MDR P. aeruginosa, a thermal injury model was used. Survival rate, and systemic spread of the infection were evaluated. Histopathological examination of the animal dorsal skin was also done for monitoring the healing and cellular changes at the site of infection. Survival rate in the treated group was 100% relative to 40% in the control group. A decrease of up to 3 logs of bacterial count in the blood samples of the treated animals relative to the control group and a decrease of up to 4 logs and 2.3 logs of bacteria in lung and liver samples, respectively were observed. Histopathological examination revealed more enhanced healing process in the treated group. Accordingly, by promoting healing of infected MDR P. aeruginosa burn and by reducing systemic spread of the infection as well as decreasing mortality rate, Ahl-1 hydrogel application is a promising strategy that can be used to combat and control P. aeruginosa burn infections.

AbstractPotentilla anserina L. is not only a medicinal plant, but also a traditional cuisine. Hence, an acute toxicity study was performed to confirm its safety profile. Forty Kunming mice were randomly divided into two groups: control group and P. anserina L. extract group. Using the maximum dosage method, the P. anserina L. extract group was given the maximum dose within 12 h, equivalent to 345.6 g/kg crude drug. The control group was given distilled water. After administration, toxicity symptoms of mice were observed, body weight and food intake were recorded. After 14 days, blood was collected to measure biochemical parameters, autopsy was carried out to observe the changes of organs, and the vital organs were separated, weighed, and preserved for histopathological examination. The results showed that P. anserina L. extract group had no toxic symptoms. The activity, weight, and diet of mice were normal, and no abnormality was found in organ index, renal function, liver function, anatomical observation, and histopathological examination. Therefore, the maximum oral dosage (345.6 g/kg) of P. anserina L. was good safety. This study indicated that P. anserina L. had a large safety range and the clinical application was safe.

The aim of this study was to assess the effect of local application of essential oil of Pistacia atlantica kurdica (EOK) gel in treatment of experimentally induced periodontitis in rats and its effect on osteoclastogenic bone markers. Twenty-four male Wistar rats of 250 to 350 g were used in this study and were allocated into four groups. Control negative (without induced periodontitis), control positive (induced experimental periodontitis left without treatment), treatment control (induced experimental periodontitis and treated with Chlorhexidine gel) and EOK treated group (induced experimental periodontitis treated with EOK gel). The animals were sacrificed after 30 days, and the mandibular central incisor and surrounding tissue were dissected from the mandible and further processed for preparing H&E slides. Inflammatory cells, osteoclast cells, and periodontal ligament (PDL) were examined and measured histologically. Finally, the mean concentrations of both markers, receptor activator of nuclear factor kappa-Β ligand (RANKL) and (Interleukin-1β) IL-1β, were analyzed by ELISA. A significant reduction of inflammatory reaction and osteoclast numbers with improvement of PDL and low mean concentrations of RANKL and IL-1β were seen in the EOK treated group in comparison to the control group and the chlorhexidine group as well. The extract showed a protective effect in the healing of periodontitis that had been induced in rats and decreased bone resorption by down regulation of serum RANKL and IL-1β markers.

AbstractStanozolol is an anabolic-androgenic steroid which is commonly abused by athletes for improved energy, appearance, and physical size. It has been previously shown to cause changes in behaviour and has various physical effects. Studies have previously been conducted on its neurotoxic effect on the central nervous system (CNS), which are typically psychological in nature. This study was performed to investigate the apoptotic effect of stanozolol on different parts of the rat hippocampus. Sixteen male Wistar rats were divided randomly into two groups (experimental and control). The experimental group received subcutaneous injections of stanozolol (5mg/kg/day) for consecutive 28 days, whereas the control group received saline using the same dosing schedule and administration route. After routine procedures, coronal sections of rat brain were stained with Toluidine blue and TUNEL for pre-apoptotic and apoptotic cell detection, respectively. In order to compare groups, the mean number of TUNEL-positive and pre-apoptotic neurons per unit area were calculated and analysed. Histopathological examination revealed that the mean number of pre-apoptotic and apoptotic neurons in the CA1, CA2, CA3 and DG areas of the hippocampus were significantly increased in the stanozolol treated group. In conclusion, stanozolol abuse may induce pre-apoptotic and apoptotic cell formation in different regions of the hippocampus.

Abstract The treatment of extensive skin burns remains as a challenge for health care personnel. This study aimed to compare the combination of bone marrow and wheat flour with standard treatment on animal models. In this experimental study, 45 male rats were randomly assigned into three groups as follows: The first group was control (no treatment), the second group received bone marrow and wheat flour combination topically, and the third group received standard treatment (1% silver sulfadiazine). The treatment lasted for up to 21 days. On the 22nd day, the rats were killed. The number of blood vessels and hair follicles was measured in the burn wound bed. The area and depth of the wound were also measured. Data were analyzed using SPSS software version 16. The results showed that, complete closure of the wound was better in the bone marrow treated group compared with the group receiving the silver sulfadiazine and the control group. Furthermore, the wound healing was better in the silver sulfadiazine group compared with the control group. Microscopic examination revealed a significant increase in the number of hair follicles and blood vessels in the bone marrow and silver groups compared with the control group. The results showed that, the group treated with bone marrow, because of the presence of mesenchymal and stem cells can cause stimulating angiogenesis and producing vegetative tissue, hence it improved maturation, shrinkage, and contraction of the wound in comparison with the silver sulfadiazine and control groups

Adenosine is a protective regulator that act endogenously to restore equilibrium of cellular energy in response to tissue trauma. It can perform such function of different systems in the body by activation of adenosine receptors. Study the effects of systemic administration of the adenosine on tongue and salivary glands tissues in the rabbit model. Thirty male rabbits of body weight of 1.5 ± 0.25kg were included in the study. In control group (15 animals), one ml of distilled water was injected intraperitoneally while in treatment group (15 animals) were injected by adenosine intraperitoneally at a dose of one mg/ml, All animals were sacrificed after 30 days. Serum samples were separated and used for analysis of adenosine deaminase (ADA)and glutathione(GSH). Tissue samples sections from tongue and salivary glands were stained with hematoxylin-eosin (H&E) and examined under a light microscope for histological changes by a blinded pathologist. Histological sections in treatment group showed congestion of blood vessels and infiltration of inflammatory cells with mild hemorrhage among acini of salivary glands. Increased level of adenosine in the body microenvironment may affect tongue and salivary glands tissues by modulating some processes including inflammation and blood vessels.

Fifty healthy male Sprague-Dawley rats were divided into five groups (n = 10 each). Each group was fed with camel milk pure curd mass and its mixes for 16 days. At the end of the experiment, rats were sacrificed to collect the samples from the blood serum. Blood serum biochemical parameters total protein, cholesterol, glucose, albumin, triglycerides; the enzymatic activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase were determined on the A25 automatic analyser, and peptide toxicity analysed by the reference method. The statistical data have shown no significant differences in body weight gain in all groups. Total protein decreased in group II, IV, and V; however, it increased in group III compared to the control group. Cholesterol grew up in group II and it slightly increased in group V, dropped in groups III and IV compared to group I result. Glucose increased in groups II, III, IV compared to group I; still, group V results show a slight decrease. Albumin decreased in group IV, yet in group V it increased than the group I result. Simultaneously, groups II and III results were changed with less percentage. Triglyceride grew up in groups II, V, and it dropped significantly in groups III, IV compared to the control group. De Ritis ratio of enzymes in groups II, III, and IV fluctuated between 1.31 and 0.98 IU/L; however, group V demonstrated significant data versus group I. Diets peptide toxicity in all groups was lower than control group data. The experimental results indicated that curd mass from camel milk could be used as a pure or with additives and it did not discover the observed side effects.

Monosodium glutamate (MSG) is widely used as a food additive. Excessive consumption of monosodium glutamate has also been shown to affect the liver and kidneys, causing damage to these tissues because of oxidative stress leading to increased production of reactive oxygen species (ROS). The purpose of the study described in this paper was to find out how the liver and kidney toxicity caused by monosodium glutamate can be mitigated using pectin. To this end, 30 albino mice females were divided into four groups. The animals were distributed in special cages. 12-15 weeks with an average body weight of 60 grams. The animals were divided into four groups: the experimental control group (1) comprising 5 female mice were given normal drinking water and the treated group (2) comprising 10 female mice were given monosodium glutamate at a dose of 3 g/kg body weight in drinking water. For three weeks, the treatment group (3) comprising 10 female mice was given pectin at a dose of 300 mg/70 kg body weight in drinking water immediately after the monosodium glutamate dose for three weeks and the pectin group (4) comprising 5 female mice were given Pectin at a dose of 300 mg/70 kg body weight in drinking water for three weeks. The mice were then anesthetized, dissected, and liver and kidney samples were taken from female mice and kept in a 10% neutral formalin solution to make tissue segments. The results showed many histological changes in the liver, such as congestion of the central vein, widening of the sinuses, and the appearance of signs of the death of most hepatocytes, infiltration of the central vein and an invasion of inflammatory cells around the central vein with the emergence of several gaps within the cells. Many of them cavity with the death of most of the tubule cells, the closure of some of them and the expansion and infiltration in others and bleeding inside the tissue. Pectin therapy has led to the disappearance of most of these changes and the emergence of a clear improvement in hepatic and renal tissue.
