The objective of the present study was to assess the effects of various doses of Azorubine which is a food additive on the female reproductive organs in Sprague Dawley rats. Twenty four female Sprgue Dawley rats were divided randomly into 4 equal groups. Group 1(control group), group, 2, 3 and 4 were received Azorubine (5, 10 and 20 mg/kg) orally, daily for 30 days respectively. Blood samples were taken for estimation of white blood cells, red blood cells, hemoglobin and platelets, in addition Luteinizing, follicular stimulation, estrogen and progesterone hormones from the sera. The reproductive hormones levels affected drastically under the effects of different doses of treatment like Luteinizing hormone (0.69±0.25, 0.60±0.75 and 0.55±0.63), Follicular Stimulation hormone (0.17±0.11, 0.13±0.33 and 0.3±0.45), Progesterone hormone (0.50±0.77, 0.14±0.56 and 0.10±0.85), and estrogen hormone (0.45+0.43, 0.30±0.29 and 0.14±0.27) hormones were decreased significantly (P˂0.05) in groups of rats treated with each 5, 10 and 20 mg/kg doses of Azorubine respectively. Histopathologically, the ovaries treated with 5 mg/kg doses of Azorubine showing follicles at the beginning stages of growth with no Graffian follicle while the ovaries with 10 mg/kg doses of Azorubine contain fully grown Graffian follicles with no follicles at various stages as well as those with 20 mg/kg doses of treatment displaying no mature Graffian follicle with many atretic and shrunk follicles. The hematological outcomes are significantly affected by this food additive. The results of this work is concluded that Azorubine can be considered as one of the most important causes of infertility, hormonal disturbances and irregular estrus cycle in the female rat.

Tartrazine is a synthetic organic azo dye widely used in food and pharmaceutical products. The current study aimed to evaluate the possible adverse effect of this coloring food additive on renal and hepatic structures and functions. Also, the genotoxic potential of tartrazine on white blood cells was investigated using comet assay. Twenty adult male Wistar rats were grouped into two groups of 10 each, control- and tartrazine-treated groups. The control group was administered orally with water alone. The experimental group was administered orally with tartrazine (7.5 mg/kg, b.wt.). Our results showed a marked increase in the levels of ALT, AST, ALP, urea, uric acid, creatinine, MDA and NO, and a decreased level of total antioxidants in the serum of rats dosed with tartrazine compared to controls. On the other hand, administration of tartrazine was associated with severe histopathological and cellular alterations of rat liver and kidney tissues and induced DNA damage in leucocytes as detected by comet assay. Taken together, the results showed that tartrazine intake may lead to adverse health effects.

Aim: The aim of the study was to investigate the immunomodulatory activity of areca nut extract. The phytochemical content and phenolic composition of the extract were also determined. Materials and Methods: An extract of areca nut was prepared using 96% ethanol and subsequently screened for phytochemical content using a high-performance liquid chromatography (HPLC) method. The immunomodulatory activity of the extract was tested in 35 Sprague-Dawley rats, divided into four groups: One control group and three experimental groups in which the rats received 500, 1000, or 1500 mg/kg of oral areca nut extract biweekly (BW). The extract was orally administered 14 days before the intraperitoneal challenge with Staphylococcus aureus (1×108 CFU/mL). On the 14th day of the experiment, rats in all the four groups were sacrificed. Measurement of the levels of red blood cells, hematocrit (Hct), hemoglobin (Hb), white blood cells (WBCs), lymphocytes, monocytes, neutrophils, basophils, eosinophil, and macrophages were recorded. The activities of serum glutamate oxalate transaminase, serum glutamate pyruvate transaminase, urea, and creatinine were also determined. Results: Areca nut was found to contain an alkaloid, tannin, and flavonoid compounds. HPLC analysis revealed the presence of catechin as the major compound along with quercetin. Administration of areca nut extract in rats infected with S. aureus produced a significant increase in the concentration of WBC but did not affect Hct, Hb, and other cell types. Among the different doses tested, 1000 mg/kg BW was found to be most effective in cellular immunity models. No harmful effects on the liver and kidney functions were observed. Conclusion: The antioxidant activity of areca nut might be attributed to the presence of catechin and quercetin. Administration of areca nut extract increased the number of WBCs and improved the activity and capacity of macrophages significantly in rats infected with S. aureus.

The ovaries represent the female reproductive organs that determine the women's fertility status and their systemic and oral health, correlating to sex steroid hormone alteration. This study aimed to investigate the effect of cassava leaves extract treatment to SOD expression in the animal model-ovaries after Porphyromonas gingivalis injection. 15 female Sprague Dawley rats were used and divided into five groups: (1) control without cassava leaves extract treatment (C); (2) P. gingivalis without cassava leaves extract treatment (T1); (3) P. gingivalis and cassava leaves extract (T2); (4) P. gingivalis and vitamin C (T3); and (5) P. gingivalis and metronidazole (T4). Animal were euthanised at day seven after the initial treatment to collect ovaries. The ovaries sections were immunohistochemically stained to quantify SOD expression using light microscope while the Image J software was used to quantify the SOD expression. The results showed that all of the follicle types had the same intensity of SOD expression. Most of the follicles exhibited low intensity of SOD expression, except for atretic follicles. In conclusion, P. gingivalis and cassava leaves extract influenced SOD expression in the ovaries of animal models, which increased the SOD expression.

The golden trevally fishes (Gnathanodon specious) (2.19 ± 0.23 g) were cultured in glass tanks with density of 20 fishes/tank and they were fed supplemental diets of different MOS concentrations (0; 0.2; 0.4 and 0.6%) for 90 days. Collected data included growth rate, survival rate and some hematological characteristics of this fish. The results demonstrated that MOS supplementation did not affect growth performance, erythrocyte density and blood cell size, however the survival rate was significantly increased. On the other hand, the total number of white blood cells (BC) on the 60th day in the fish fed with MOS supplements (5.78–6.96 × 104TB/mm3) was higher than that in the control group (only 5.43 × 104TB/mm3) with the largest total leukocytes (6.96 ± 0.50 × 104TB /mm3) at 0.2% MOS (p < 0.05).

Purpose This paper aims to evaluate the therapeutic potential of apple extracts against thrombocytopenia, i.e. decrease in platelet count. Design/methodology/approach Male Sprague Dawley rats were used to evaluate therapeutic potential of apple extracts. Diets enriched with apple fruit and seed’s ethanolic extract were provided to normal and KBrO3-induced thrombocytopenic rats for 60 days. KBrO3 was administered at level of 85 mg/Kg of body weight of rats to intentionally decrease the platelet count. Platelet count and other hematological parameters were monitored at monthly intervals to evaluate therapeutic effect of apple extracts against thrombocytopenia. Findings The results of current research portrayed that both apple seed and fruit extracts enriched diets increased the platelet count significantly (p < 0.05) in thrombocytopenic rats. It was observed that apple fruit extract-enriched diet (AFE) raised the platelet count to 14.72 and 33.07 per cent in normal and thrombocytopenic rats, respectively. Apple seed extract-enriched diet (ASE) raised the platelet count to 11.08 and 32.90 per cent in normal and thrombocytopenic rats, respectively. Other hematological parameters including white blood cells, red blood cells and hemoglobin were also significantly increased. Originality/value Thrombocytopenia is uprising problem in developing world including India and Pakistan accompanied by different diseases especially dengue and related complications. Because of questioning on therapies against thrombocytopenia, research on diet-based therapies, as a substitute to synthetic one, is increasing. Diet rich in antioxidant compounds including apple fruit and seeds are the limelight of manuscript.

Selenium plays an important role for maintaining complex and adequate nutrition of fattened young pigs. It also has a big biological importance to maintain growth and health, as well as for biochemical and physiological processes This study presents the results of a production experiment to determine the effect of organic and inorganic forms of selenium on growth indicators, immunohematological blood parameters and slaughter qualities of fattened pigs in period I and II. Test feeding with various forms of selenium has been implemented with two groups of analogs (N = 60; n = 30), taking into account age and live weight. The experiment was conducted on castrates of large white breed, which were divided into two groups of 30 heads each following the principle of analogues (taking into account their age, live weight). The studied fattened pigs received standard complete feeds of the SK-5 and SK-6 types for a period of 105 days. Growing pigs were fed with organic selenium for 20 mg/kg as part of the feed 64 mixture per head in the first and second period of fattening, while the animals of the control group were fed with 0.3 mg/kg of the inorganic form of selenium. Including a chelated form of selenium in the complete feed of castrates at the rate established in the course of scientific and economic studies has led to 757 g of average daily gain, which is 8.1% more as compared to the control group. The concentration of red blood cells in the blood of growing pigs fed with 20 mg/kg of selenium chelate increased by 6.3%, hemoglobin – by 2.4%, and white blood cells – by 7.1% as compared to the control. Feeding organic selenium to fattened young pigs contributed to a significant increase in specific units of protein activity by 38.65% (p < 0.01), BASC – by 7.63%, as well as lysis – by 40.06% (p < 0.05), and phagocytic activity by 3.33% in blood serum as compared to the control. The half-carcasses of hogs who had received fed rations including selenium chelate fetured slaughter weight and slaughter yield, respectively, higher – by 6.4 and 0.6% as compared with the control analogues. The use of the established norm of organic selenium in the diets of fattened young pigs according to the results of production testing is economically profitable and contributes to a per-head profit of 420 rubles.

Vanadium is a metal present in particulate matter and its reprotoxic effects have been demonstrated in males and pregnant females in animal models. However, the effects of this metal on the reproductive organs of nonpregnant females have not been sufficiently studied. In a vanadium inhalation model in nonpregnant female mice, we found anestrous and estrous cycle irregularity, as well as low serum concentrations of 17β-estradiol and progesterone. A decrease in the diameter of secondary and preovulatory follicles, as well as a thickening of the myometrium and endometrial stroma, was observed in the vanadium-treated mice. There was no difference against the control group with respect to the presence of the estrogen receptor α in the uterus of the animals during the estrous stage. Our results indicate that when vanadium is administered by inhalation, effects are observed on the female reproductive organs and the production of female sex hormones.

These experiments evaluated the leukocyte as a potential source of oxygen free radical (OFR) generation during reperfusion injury in post-ischemic skeletal muscle. The infrarenal aorta of heparinized Sprague-Dawley rats was clamped for 90 min, declamped, and reperfused for 60 min. Hindlimb muscle resting transmembrane potential difference (Em) and high-energy phosphate content were determined at base line, during ischemia, and on reperfusion. Four groups were studied: a control group, a second group receiving superoxide dismutase and catalase (SOD + CAT) on declamping, a third group receiving dimethylmyleran (DMM) 7 days before the experiment to obtain a selective leukopenia (white blood cells = 1,210 +/- 144/mm3, neutrophils = 1.2%), and a fourth group pretreated with allopurinol (ALLO). During the ischemic period, resting Em was significantly depolarized (-78.6 +/- 0.5 mV from -90.3 +/- 0.3; P less than 0.05) in the control group, whereas creatine phosphate (CP) was depleted and ATP maintained. Data collected during the ischemic phase of the three other groups were similar to the control group (P = NS). On reperfusion, persistent depolarization of resting Em was observed despite restoration of muscle CP content in the control and ALLO groups (-75.4 and -77.0 mV, respectively). In contrast, significant repolarization of resting Em was noted after reperfusion in the SOD + CAT and DMM groups (-86.5 and -88.6 mV, respectively). These data implicate leukocyte-generated OFR as mediators of reperfusion-associated cellular membrane injury in postischemic skeletal muscle.

The aim of the study was to detect and compare the haemostatic variables and bleeding after 7‑days administration of carprofen or meloxicam in clinically healthy miniature pigs. Twenty-one clinically healthy Göttingen miniature pigs were divided into 3 groups. Selected haemostatic variables such as platelet count, prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen, serum biochemical variables such as total protein, bilirubin, urea, creatinine, alkaline phosphatase, alanine aminotransferase and gamma-glutamyltransferase and haemoglobin, haematocrit, red blood cells, white blood cells and buccal mucosal bleeding time were assessed before and 7 days after daily intramuscular administration of saline (1.5 ml per animal, control group), carprofen (2 mg·kg-1) or meloxicam (0.1 mg·kg-1). In pigs receiving carprofen or meloxicam, the thrombin time was significantly increased (p< 0.01) compared to the control group. In animals receiving carprofen, serum urea and creatinine were significantly decreased, compared to the control (p< 0.01) or meloxicam (p< 0.05) groups. In pigs receiving meloxicam, serum urea was significantly decreased (p< 0.05) compared to the control group. Significant differences were not detected in other haemostatic, biochemical variables or bleeding time compared to other groups or to the pretreatment values. Intramuscular administration of carprofen or meloxicam in healthy miniature pigs for 7 days causes sporadic, but not clinically important changes of selected haemostatic variables. Therefore, we can recommend them for perioperative use, e.g. for their analgesic effects, in orthopaedic or other surgical procedures without increased bleeding.
