Motor and sensory assessment of Sciatic Nerve Function Following Surgical Excision of induced fibrosis in a rabbit model
type: item
description: The current study was conducted to evaluate the surgical removal of iatrogenic sciatic nerve fibrosis that occurs after intramuscular injection with diclofenac sodium. A total of 20 healthy local- breed male rabbits were randomly divided into two equal groups (n=10). All rabbits underwent general anesthesia, followed by surgical exploration of the sciatic nerve in the left hind limb and injection of (1.5mg/kg) diclofenac sodium (2.5%) intraneurally to elicit an experimental iatrogenic sciatic nerve injury. All of the experimental animals was left for 14-day post operation and was divided into two groups, control groups were left without treatment, dissection group group underwent surgery to open the site of the induction surgery and removing the fibrosis from and around the sciatic nerve. For the clinical assessments, motor and sensory functions were evaluated weekly from the first week post operation until the end of the 84-day study period. Motor and sensory evaluations revealed statistically significant differences between the control group and dissection group on all of the clinical evaluation periods, the postoperative period confirmed an earlier clinical improvement in the treatment group in the knuckling sign and gait of the experimental animals with a better recovery muscle contraction force, the sensory evaluation revealed an earlier recovery and return of sensation in the dissection group when compared with the control group.

Protective Effect of Resveratrol on Isoproterenol-Induced Myocardial Damage in Male Rats
type: item
description: This study evaluated the cardioprotective effects of resveratrol against isoproterenol-induced myocardial infarction in male Sprague-Dawley rats. Forty rats were randomly divided into four groups: control, resveratrol-treated, isoproterenol-treated, and a combined treatment group. Resveratrol was administered orally at 20 mg/kg/day, while isoproterenol was given intraperitoneally at 100 mg/kg. The results revealed that isoproterenol significantly increased serum levels of oxidative stress markers (MDA), inflammatory cytokine (TNF-α), triglycerides, cholesterol, and cardiac enzymes (CK-MB, cTnI, LDH), while reducing total antioxidant capacity (T-AOC) (P ≤ 0.05). esveratrol treatment significantly mitigated these alterations, restoring antioxidant levels and reducing lipid and enzyme elevations. The combination treatment group showed intermediate values, indicating a partial protective effect. In conclusion, resveratrol demonstrates promising cardioprotective properties through its antioxidant, anti-inflammatory, and lipid-lowering actions, suggesting its potential as a preventive agent against oxidative and inflammatory cardiac damage.

Phytogenic Feed Additives in Ruminant Nutrition: Rumen Modulation, Performance, and Sustainability – A Review
type: item
description: In order to satisfy consumer demands for natural and sustainable products, the livestock industry must adapt to stricter laws governing the use of antibiotic growth promoters (AGP). Phytogenic feed additives (PFAs) have drawn a lot of interest in this context as a substitute to enhance ruminant performance. Essential oils, polyphenols, saponins, tannins, and other plant-derived substances are all included in the large class of compounds known as PFAs. These substances include a wide variety of bioactive compounds that have intricate and multifaceted effects on the performance and health of ruminants. An overview of the state of knowledge regarding the application of PFAs in ruminant production is given in this review. It encapsulates their primary modes of action, which include host metabolism, digestive enzyme activity, and rumen microbiota modulation. The review specifically addresses PFAs' ability to alter rumen fermentation in a way that enhances volatile fatty acid (VFA) production, lowers ammonia concentration, and—above all—decreases enteric methane production. Examined are the ensuing impacts on productive performance. Because of their immunomodulatory, anti-inflammatory, and antioxidant qualities, which can lessen stress and increase resistance to disease, PFAs may also contribute to the advancement of animal welfare. The study also discusses some of the drawbacks of using PFAs, including response variability based on the plant source, extraction technique, dosage, and diet. This emphasizes how production and use of PFAs require standardization and quality control. This review paper concludes by summarizing the body of research on PFAs' use in ruminant production, including information on their mode of action, performance effects, possible health advantages, and environmental effects. Designing more sustainable and effective ruminant production systems that satisfy consumer demands and legal requirements is possible with the knowledge provided in this paper…

Pharmacological Interaction Between Alpha-Lipoic Acid and Propofol-Induced General Anesthesia in Rats Model
type: item
description: Alpha-lipoic acid (ALA) is an endogenous antioxidant that is involved in the metabolism of energy inside the mitochondria, working as a cofactor of the enzyme-catalyzed reaction. It has strong free radical scavenging activity, which reduces all oxidative stress. The experimental study carried out the careful assessment of alpha-lipoic in adult male rats (n=29). The proposed study was undertaken to evaluate the effects of alpha-lipoic acid on Propofol-induced general anesthesia in rats. The median effective dose (ED50) of alpha-lipoic acid was 45.43 mg/kg upon the intraperitoneal injection method via the up-and-down method. The paper further examined the effects of three doses of alpha-lipoic acid (30 , 60 and 120 mg/kg of 6 rats / group) on the onset, duration, and recovery periods of Propofol-induced anesthesia. The results indicated that the onset time with recovery periods was significantly reduced and the duration of anesthesia prolonged with a dose-dependent effect compared to that of the control group (p < 0.05). These statistics suggest that ALA can potentiate the effects of propofol and might have clinical implications in terms of improving the quality of anesthesia and recovery processes.

Histological and Structural Development of the Liver of Rats from the Embryonic Stage to Adulthood
type: item
description: This study was conducted in the animal house of the College of Veterinary Medicine/Tikrit University. The study included (24) white rats and 4 male rats used for mating purposes only. They were divided into four equal groups, each group containing 6 samples of the liver of white rats (embryonic stage, one day old after birth, 7 days old after birth and adulthood stage). The study of the liver using the microscope showed that there was a gradual growth between the embryonic liver and the mature liver at the level of liver cells, blood sinuses, bile ducts, and liver lobes. The embryonic liver had simple squamous endothelium of the central vein, scattered hepatocytes, and hepatocyte aggregates of hematopoietic cell types, such as lymphocytes, red blood cells, and at times megakaryocytes. The hepatocyte packing associated with eosinophilic cytoplasm and lipid droplets, dilated sinusoids containing hematopoietic cells, white blood cell infiltration in the peripheral connective tissue. Seven days after birth, columns of hepatocytes were formed, branches of the portal vein and bile ducts were seen with the infiltration of white blood cells, and the isolated foci of hematopoietic cells and primitive bile ductules were identified. Polygonal hepatocytes in the adult liver were radially organized around the central vein, and a well-integrated sinusoidal network was present, which harbored Kupffer cells, and this indicated structural and functional maturity. These data demonstrate the process of hepatic maturation of embryonic hematopoiesis into postnatal differentiation and vascular maturation, which leads to a functional structure with parenchymal architecture.

Histological Changes Associated with Exposure to Lead Acetate and Evaluation of the Therapeutic Role of Berbin Extract in Female Albino Rats and Their Fetuses
type: item
description: The current study aims to investigate the effect of lead acetate on pregnant female rats and their fetuses, as well as the protective role of the aqueous extract of the albino plant against lead exposure. This experiment was conducted in the animal house of the College of Veterinary Medicine at Tikrit University. Thirty female albino rats, weighing between 180-200 grams and three months old, were placed in plastic cages and paired with males of the same strain. They were then randomly divided into three groups, each consisting of five pregnant females. The first group served as the control. The second group was treated with lead acetate from days 10 to 19 of pregnancy. The third group received lead acetate during days 10 to 19 of pregnancy and also received the aqueous extract of the albino plant throughout the pregnancy. The daily oral dose of lead acetate50 mg/kg and the berberine extract was 200 mg/kg. Histological examination of the control group’s liver showed hepatocyte rows and a network of blood sinusoids containing Kupffer cells. In the kidneys, the capsular space and Bowman's capsule were nearly normal, as were the convoluted tubules. In the second group, hepatocytes experienced atrophy and dilatation of the blood sinusoids containing Kupffer cells. The kidneys of this group showed leukocyte infiltration, congestion with fibroblast proliferation, thickening of the capillary walls, and irregular tubule sizes. In the liver of the third group, the central vein exhibited blood hyperemia and leukocyte infiltration. This group showed limited atrophy, slight dilatation of the capsular space, limited epithelial cell sloughing, and near-normal convoluted tubules.

Morphological and histological structure of the cerebellum of turkey at the different levels of age (comparative study)
type: item
description: This study aimed to investigate the structural development of the brain and cerebellum in local turkeys from hatchling (1 day) to adulthood (2 months, 3-7 months, and adult age). Following euthanasia, the skulls were dissected to extract the cerebellum, which were then rinsed and preserved in 10% neutral buffered formalin for histological analysis. The morphology revealed two cerebellum lobes, Histological examination identified three layers in the cerebellar cortex across all age stages. In the first month, delicate meninges and a few glial cells accompanied small to medium-sized neurons and numerous blood capillaries. As the turkeys aged, there was a notable increase in glial cells and larger, with more developed meninges. Additionally, cavitation’s around neurons and nerve bundles were observed, particularly at one year of age. The cerebellum comprised two layers: an outer cortex with a pial meningeal membrane, consisting of a molecular layer with small nerve cells and glial cells, and a Purkinje layer that increased in size with age. The internal granular layer was broad, filled with small nerve cells and glial cells. Overall, the study concluded that the brain and cerebellum of turkeys exhibit well-developed nerve and glial cell layers, similar to those found in mammals, reflecting significant structural changes as they mature.

Histological Study of the Chicken Retina and Associated Ocular Structures
type: item
description: Comparative ocular and histological studies is the high degree of development of the anatomical elements and superior visual acuity make the avian eye (particularly, the domestic hens) an ideal model to study. This study aimed to study the retina and other ocular structures of the domestic chicken (Gallus gallus domesticus) in histological point of view. Twenty samples of the eyeballs were taken out of healthy hens of approximately 40 days old and the weight range was 1.5-2.0 kg. The samples were processed like any other normal biological material, whereby they were placed in 10 percent neutral buffered formalin, dehydrated, and embedded like any other normal histological material. The overall architecture of the tissues in the sections was observed regarding hematoxylin and eosin (H&E) stain. At low and high magnification microscopic examination revealed the typical multilayered structure of the avian retina. Besides the five layers of cornea, other eye body tissues were discovered and documented including sclera (dense collagen fiber), scleral supportive cartilage, skeletal muscle bundles within sclera and the adjacent vascularized pigmented choroid to the retina. This research increases our understanding of the anatomy of chicken eye tissues and provides a foundation with which comparative and veterinary research on chicken eyes can build on

Impact of Alcoholic Cabbage Extract on T3, T4 & TSH Hormones Levels and Histological Architecture of the Thyroid Gland in Adult Male Rats
type: item
description: The present study sought to investigate the effects of alcoholic white cabbage extract on the thyroid gland by analyzing its morphological and functional status in experimental rats. The adult rats at the age of three months were obtained from the Animal House of the College of Veterinary Medicine, Tikrit University in one month (9/9/2024 to 2024/10/9). Twelve mature male albino rats (weighing between 250 and 300 g) were randomly assigned to three equal groups. Each group included four rats. The first group (G1) served as the control group, the second group (G2) was given cabbage extract at a dose of (100 mg per kg of body weight orally) three days a week for a month, and the third group (G3) received the same dose daily orally for a month. The study found no significant increase (p≤0.05) in serum TSH concentrations in group (G2). However, group (G3) rats showed a significant increase compared to the control group (G1). Blood concentrations of T3 and T4 significantly decreased (at p≤0.05) in groups (G2) and (G3) compared to the (G1) group. Histological data for the groups (G2 and G3) show a detectable alteration. Follicle size revealed aberrant, non-homogeneous colloid with a lack of vacuoles, vacuolar degeneration in follicular cells, loss of follicular cells in certain follicles, and follicles of various sizes packed with colloid and enclosed by columnar to flat epithelium. Group (G3) had enlarged or dilated follicles, no peripheral vacuoles, scalloped colloid in some follicles with flattened epithelium, degraded follicular epithelial cells, and bleeding. According to the study, cabbage extract administration causes significant histological changes in albino rats' thyroid glands, such as vacuolar degeneration, collagen fiber deposition, sloughing of follicular cells, scalloping of colloid, flat epithelium, and reduced serum concentrations of T3 and T4, potentially leading to an increase in TSH levels in the blood.

Detection of Hemolytic Activity of Brucella melitensis Antigens Loaded in Nanocarriers
type: item
description: The hemolytic potential of NPs has been the subject of numerous studies as a critical indicator of their safety in vaccine applications. In this study, the elemental compositions of Brucella melitensis Antigens (BMAs) loaded in Ca, Phosphate/ Chitosan nanocomposite created by encapsulation method. In addition, size, and surface topography were characterized by UV-VIS spectrophotometers, Energy Dispersive X-ray (EDS/EDX), and Atomic Force Microscopy (AFM) techniques. Furthermore, the cytotoxicity of Brucella melitensis antigens loaded in calcium phosphate/chitosan nanoparticles was determined by measuring the hemoglobin released from rabbit erythrocytes using a spectrophotometer at 545 nm. The results showed that λ max of BMAs, Ca, P/CsNPs were present at 1.987 at the wavelength 232 nm which differed from the absorbance values of CaP/Cs NPs and Brucella melitensis Antigens samples respectively. The main components of BMAs, Ca, P/CsNPs were C, O, and sodium, with 22.2%, 46.1%, and 20.7 % respectively and the secondary components were Ca and P with 4.4% and 1.3 % respectively. Additionally, other elements confirmed the presence of Brucella melitensis antigens in. nanocomposite. The average particle size was 30.15 nm and a total height of 107.4 nm. Additionally, the hemolysis index of BMAs, Ca, P/Cs NPs was not detectable against rabbit RBCs. We can conclude that the unique properties of CaP/CsNPs enabled the carry of Brucella melitensis antigens and were nontoxic for RBCs, suggesting potential candidates for vaccine applications against Brucella melitensis.

Role of pumpkin seed extract in improving the apoptotic pathways of hepatocytes in STZ-induced diabetic rats
type: item
description: In diabetic rats given an experimental treatment, the impact of alcoholic pumpkin seed extract (Cucurbita pepo L.) on hepatocellular mortality and inflammation was studied. One intraperitoneal injection of streptozotocin (STZ; 40 mg/kg) caused diabetes in male rats, followed by a dose of pumpkin seed extract (200 mg/kg), for three months, given every other day. TNF-α levels in diabetic rats treated with pumpkin seed extract improved to normal. Pumpkin seed extract also prevented arise in p53, Bax, caspases-3, 8, and 9, lessened hepatic damage of DNA, and slowed the rise in TNF-α levels. It also regulated apoptosis by increasing the production of Bcl-2 protein. Based on current research, pumpkin seeds may shield the liver from necrosis, apoptosis, inflammation, and DNA damage by enhancing the redox state, inhibiting p53 and caspases, and raising Bcl-2 protein. As a result of enhancing apoptotic signals, pumpkin seeds have a great deal of therapeutic promise for managing diabetes and its adverse effects on the liver.

Evaluation of the role of melatonin for protect testicular tissues from harmful effects of diclofenac in rat male
type: item
description: The aim of the current study is to evaluate the effect of melatonin as an protect testicular tissues after the harmful effects of diclofenac. Thirteen rats were used in this study, which lasted for month. Divided into 6 groups, each group contain 5 rats. The control group G1 (vehicle treated) received normal saline (0.1 ml/day). The Second group G2 (5 rats) treated with Diclofenac. (0.7 mg/Kg/B.W), The Third group G3 (5 rats) was treated with Melatonin. (0.07 mg/Kg/B.W), The Fourth group G4 (5rats) was treated with Diclofenac.(1.4 mg/Kg/B.W),The fifth group G5(5 rats) was treated with Melatonin + Diclofenac.(0.7 mg/Kg/B.W +0.07 mg/Kg/B.W),and The sixth group G6 (5 rats) was treated with Melatonin + Diclofenac. (1.4 mg/Kg/B.W +0.07 mg/Kg/B.W). The results indicate that diclofenac sodium induces significant reproductive dysfunction in male rats, characterized by degeneration of spermatogenic cells and Leydig cells. Melatonin administration appears to mitigate some of these adverse effects, particularly at the lower dose of diclofenac (0.7 mg/Kg/B.W), suggesting its potential as a protective agent against diclofenac-induced reproductive toxicity. Further studies are warranted to explore the mechanisms underlying these protective effects and to optimize treatment protocols. In conclusion, the reproductive toxicity effects of DF these effects on testicular tissues could be attenuated by treatment with melatonin.
