Erythropoietin (EPO) exhibits nonhematopoietic functions. Besides its hematopoietic functions, EPO has anti-apoptotic, anti-oxidant and anti-inflammatory activities. Tissue-protective EPO effect was confirmed in brain, myocardium, liver, and kidney injury. Mesenchymal stem cells (MSCs) are nonhematopoietic cells. It may be extracted from the bone marrow, dental pulp, adipose tissue, placenta, umbilical cord, or amniotic membrane. Pre-clinical and clinical evidence shows that MSCs derived can heal injured liver tissues, enhance liver functions, and reduce liver fibrosis. Material and Methods : Hundred male albino rats were classified into five groups equally. Some biochemical and Immunohistochemical studies of COX-2 were assessed in the liver tissue. Results: MSCs and EPO treatment ameliorated the toxic effect of GalN with a significant decrease in the mean level of ALAT, ASAT, and ammonia. The combination between MSCs and EPO showed more effective protection against GalN toxicity.

Background: Jazan region is one of the most important areas of the Kingdom that is located in the southwest of the country. It is considered one of the richest areas in biodiversity and it encompasses a large group of lizards belonging to different families. The aim of the current research is to survey different types of lizards in Jazan. Materials and Methods: Lizards were collected from Al-Aradha, AL-tuwal and Damad by hand capturing between dawn and midmorning, or shortly before sunset. Results: In this work, eight species belonging to four families (Camaeleonidae, Scincidae, Gekkonidae, and Agamidae) were collected and identified. Most of the gathered species belong to the family Gekkonidae. Conclusions: The widespread of species belonging to the family Gekkonidae may be attributed to the ability of these species to withstand various climatic conditions and to live in different habitats using the available facilities to survive and broadly distribute.

The current study to assess the antioxidant and hepatoprotective properties of Moringa oleifera seed extract versus carbon tetrachloride (CCl4)-stimulated liver damage. Materials &Methods: Male albino mice were separated into four groups for the investigation The control group (A) was given distilled water (DW), whereas the other three groups (B, C, and D) were administered CCl4 intraperitoneally (IP) (0.5 ml/kg) mixed with corn oil (vol/vol), for 8 weeks, twice a week. Group (C) was given Moringa seed extract (1g/kg) orally every day for 8 weeks, while group (D) was given corn oil orally, and the groups (C) and (D) were compared to group (B) which was given CCl4 IP. The researchers measured liver functions, blood-reduced glutathione (GSH), total antioxidant capacity (TAC), and malondialdehyde (MDA) in erythrocytes. Moreover, catalase enzymes in liver tissue homogenate were also assayed and superoxide dismutase (SOD), in addition to liver histopathology. Results : Following a CCl4 injection, liver enzymes and MDA levels were elevated. Conversely, TAC, serum albumin, total protein, catalase, tissue SOD, and blood glutathione levels were all decreased. Administration to Moringa oleifera seeds extract reduces MDA levels and enzyme activity in the liver while increasing antioxidant activity. Simultaneously, after treatments with this extract, the histological damage effects of CCl4 intoxication were also improved. Conclusion: Finally, Moringa oleifera seeds extract increased innate antioxidant activity and reduced CCl4-induced liver damage, suggesting that it might be employed as a hepatoprotective medication in the future.

Hormones are hormones secreted by the thyroid gland and their primary function is to regulate the speed of metabolism in many tissues. The thyroid gland releases its hormones into the bloodstream in response to a regulating hormone released by the pituitary gland called thyroid-stimulating hormone. It is the only organ in the body that has the ability to synthesize iodine in large quantities for use in the synthesis of thyroid hormones. It consists of two lobes, joined together by the isthmus, located above the windpipe, just below the cartilage, which is the marker for its location. The weight of the thyroid glands in humans ranges from 15-to 20 grams and the blood supply changes depending on the functioning of the gland. There are lymphatic vessels, but their function in relation to endocrine function is uncertain.

Background: The contributions of forensic entomology and arthropod in legal investigations have been known for centuries. There are many ways that insects can be used to help in solving a crime, but the primary purpose of forensic entomology is the determination of postmortem interval. The aim of this work is to evaluate the effect of scorpion venom on the decomposition of rabbits’ carcasses and on arthropods’ colonization of rabbits’ carcasses in indoor and outdoor environments. Methods: Twenty male rabbits were included in the study, divided into four groups, with 5 rabbits in each group. two groups were killed by spinal cord separation; group (1) kept in an indoor environment and group (3) in an outdoor environment. The other two groups were killed by scorpion stings (groups 2 and 4), kept indoors, and outdoor respectively. The carcasses were allowed to decompose, and arthropods were collected daily and examined morphologically. Results: The decomposition findings were less prominent in groups 2 and 4 with less maggot mass compared to the control groups. Furthermore, arthropod species were different and showed morphological changes in the form of dryness with the formation of ulcers in the larvae, appearance of irregular groves and tunnels in insects and dryness of the outer layer with damage to the ends of beetles. Conclusion: Scorpion venom affected the decomposition rate of rabbits’ carcasses and arthropods’ colonization with the difference in morphological appearance of arthropods between the control groups and scorpion stinging groups, which may be of forensic importance.

pesticide widely used throughout agriculture and veterinary practices. The present study aimed to evaluate the toxic effects of Malathion inhalation through simulation of three models of environmental toxicity in different exposure periods of acute, chronic, and subchronic doses. The histological, immunohistochemical examinations of the morphological integrity of the liver and brain, together with some biochemical (TAC, CAT, SOD, GPx and Se) and molecular (Real-time PCR for p53 and P21 mRNA) studies will be assessed to highlight the effects of the studied sub-lethal doses of Malathion. Four groups of male Wister rats were used in the experiment one for the control group and the others for subchronic, chronic and acute doses. Many toxic symptoms, a significant decrease in CAT, CAT, SOD, GPx and Se values. Malathion cause also significant disturbance in different comet assay parameters in both blood and liver tissue cells. Also, Real-time PCR for mRNA of P53 and P21 in the liver showed a significant increase in mRNA expression of P53 and P21 and a significant decrease in mRNA expression of P53 and P21 in brain tissue. P53 immunohistochemistry in liver tissue shows an increase in its activity and a decrease in hippocampus tissue cells. Many histopathological lesions such as inflammation, vacuolation, apoptosis, necrosis, and fibrosis of the hepatic tissue cells, were recorded in all treated groups.

organic manures us to focus on their exploration in agriculture. Laboratory effectiveness of Serratia spp. and Pseudomonas spp. isolates against egg hatching and infective juvenile mortality of the root-knot nematode, Meloidogyne incognita was determined. As well as performance evaluation of composted chicken manure (CM) inoculated with bacteria under greenhouse and field conditions on vegetable plants, cucumber, pepper, potato and tomato besides In vitro results after the 5 th day of inoculation, S. marcescens (A10) and Pseudomonas fluorescens PF131 isolates gained the highest inhibition of egg hatching (85.18 and 75.36%). While juvenile mortality percentages were 43.30 and 35.10% with S. marcescens (A10) and P. putida (PP29), respectively. The nematicidal effect of the tested rhizobacteria on M. incognita inhibited egg hatching and juvenile mortality was directly proportional to isolates and exposure time. Under greenhouse conditions, the interaction between rhizobacteria and CM increased the fresh potato plant's shoot weight (31.78%) and root weight (28.94 %). Furthermore, the decrease in the number of galls, egg masses, IJs/100 g soil, and RF population significantly to 69.57%, 63.37%, 12.40, and 0.147, respectively. Under field conditions, the combination of chicken manure seems to be responsible for the sustainability of rhizobacteria in situ and extends their potency for a long period. After 20 days of the field application (1.8×10 8 cfu/ml; 15 L /Fed), the reduction percentages in IJs in blocks treated with the mixture of rhizobacteria and were 88.94, 87.92, 91.27, and 9276 % in tomato, cucumber, pepper, and banana plants, respectively.
