Sixty male rats were divided into five groups (G1 and G2: control, G3, G4, and G5: orally received celecoxib (10 mg /kg), prednisolone (5 mg /kg), and curcumin (100 mg /kg) respectively. All groups 2, 3, 4, and 5 received single subcutaneous carrageenan injection, 0.1 ml carrageenan sodium (1.5 % solution in saline), in rat paw after 14 days. Serum inflammatory markers interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)), liver function tests (alanine aminotransferase \"ALT\", albumin and bilirubin), kidney function tests (urea and creatinine), platelets and white blood cells (WBCs) count were measured. The results revealed that curcumin administration induced a significant downregulation in inflammatory markers compared with the carrageenan-treated group. Also, the current results revealed that curcumin has no side effects on the liver, kidney function, and on platelets and WBCs count; on the contrary, it improved the carrageenan effect on these parameters, unlike celecoxib and prednisolone. Based on the above-mentioned findings, it could be concluded that curcumin is displayed as an anti-inflammatory with minimum side effects on hepato-renal function and hematological variables, unlike celecoxib and prednisolone.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126796672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is widely required for different physiological activities in spermatozoa including spermatogenesis, sperm motility, capacitation, acrosome response, and fertilization. Recent advancements in nanotechnology have broadened its potential applications in biomedicine, including improving animal reproductive aspects. Our research was planned fundamentally to examine the influence of calcium deficiency and calcium administration using Nano and commercial calcium in two doses for each type of calcium (1000 mg/Kg body weight (BW) and 500 mg/Kg BW once daily for 64 days orally) to reveal their effects on male reproductive function as well as regulatory mechanisms connected to male fertility. Semen examination, biochemical analyses, enzymatic antioxidant, lipid peroxidation, and testis histopathology were all evaluated after 64 days. Our results revealed that Serum calcium, testosterone, and ABP levels, sperm count, motility, and percentage of intact acrosomes, as well as testicular antioxidant enzymes, were all considerably lower in the calcium-free diet group, whereas sperm abnormalities and testicular Malondialdehyde were significantly higher. In calcium (Nano and commercial) administered male rats, serum calcium, testosterone, and ABP levels, sperm count, motility, percentage of intact acrosomes, and testicular antioxidant enzymes all increased significantly, whereas sperm abnormalities and testicular Malondialdehyde dropped dramatically. Overall, these results point to a strong link between Ca, sperm function, and fertility outcomes. what's more, Ca supplementation, particularly nanoparticles could efficiently improve male reproductive function and fertility.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128471473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infectious coryza is an acute upper respiratory infection that causes significant economic and productivity losses worldwide. Despite the use of prophylactic measures and treatment, the infection persists due to antibiotic resistance and a superior advantage in its outer protective antigen, resulting in a complicated disease pattern. Definitive diagnosis of the disease is hindered due to major challenges that are related to the complicated bacteriological isolation of the bacterium, which could be isolated only during the acute stage of infection, in addition to the fastidious and slow growth pattern of the organism. Egypt, as a key supporter of the chicken sector, is constantly threatened by this insidious infection, necessitating the development of new technology to combat it. The significance of A. paragallinarum infection, the prevalence of serotypes, clinical signs, characterization, diagnostic tools, prophylactic approaches, and therapies are discussed in this review. This article aims to provide more knowledge about the disease organism, newer diagnostic and therapeutic techniques for efficient containment of the organism therefore reducing the disease's negative economic impact.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121117300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to assess the protective effects of vitamin E, curcumin, and ginger in male rats against the side effects of levofloxacin (LFX).Ninety male Wistar rats were placed into six groups, each of 15 animals. Groups 1 and 2 received distilled water or olive oil and kept as normal controls, while groups 3-6 received LFX [10 mg/kg body weight (BW)] alone or in combination with vitamin E (100 mg/kg BW.), curcumin (200 mg/kg BW.) or ginger (200 mg/kg BW.), respectively. All medications were administered orally via gavage once a day for 5 successive days. Samples of blood were collected at zero day , 7th and 14th day posttreatments for biochemical analysis, while liver and kidney tissues were dissected and subjected to antioxidants estimation. Levofloxacin administration caused hepatic and renal damage evidenced by significant increase in serum liver enzymes, urea (76.43±3.70, 72.67±0.47, 75.00±6.42), creatinine (2.48±0.01, 2.48±0.01, 2.50±0.01), total cholesterol (166.67±6.81, 174.00±4.04, 176.00±2.88), triglycerides (269.67±5.84, 289.33±4.91, 249.67±1.86), and low density lipoproteincholesterol (LDLC) (243.00±7.09, 213.67±5.03, 226.33±5.45) levels.

The birds were weighted and assigned to equal six treatment groups as following: T1 (0% IWM), T2 (20% IWM), T3 (40% IWM), T4 (60% IWM), T5 (80% IWM), and T6 (100% IWM) in a completely randomized design.

The feed intake decreased gradually as IWM increased in the diet. Feed conversion ratio was significantly lowest (P < 0.05) in birds fed 60% IWM (1.65). It was revealed that the relative weight of gizzard, liver, intestine, and abdominal fat were significantly (P < 0.05) affected by the dietary inclusion of IWM. The highest recorded value of abdominal fat percent was (3.36) in group fed 100% IWM. The lowest recorded value of liver % was (1.91) in group fed 60% IWM. Cost and return analysis revealed that the feed cost decreased because IWM increased in the diet. Total return and net profit were significantly highest in birds fed 60% IWM. Also there was an improvement in the pancreatic digestive enzymes activities with dietary inclusion of IWM. There were significant increase in amylase and lipase activities while significant decrease in protease activity. There was a significant increase in the total cholesterol as dietary IWM increased.

Aeromonas species are opportunistic pathogens that affect many aquatic animals and human. These pathogens cause septicaemia, ulcerative and haemorrhagic diseases, and mortality in different fish species. They possess large number of virulence factors in addition to inherent resistance to various antimicrobials and ability to form biofilms with the help of quorum sensing.
