Turkish Journal of Medical Sciences

Bacterial lipopolysaccharide (LPS) triggers synthesis of nitric oxide (NO) and superoxide (O_2^{.-}). O_2^{.-} can react with NO to produce the powerful oxidant peroxynitrite (ONOO-). The presence of 3-nitrotyrosine (3-NT) in tissues is often used as a marker of ONOO- production. Vitamin A, vitamin C, and melatonin are potent antioxidant molecules. We sought to clarify this issue by examining the effects of vitamin A (15,000 IU/kg/day), vitamin C (600 mg/kg/day), and melatonin (25 mg/kg) on 3-NT formation in heart tissue in a guinea pig model of LPS-induced endotoxemia.

Aphrodisiac Activity And Curative Effects Of Pedalium Murex (L) Against Ethanol Induced Infertility In Male Rats, Gunasekaran Balamurugan, P. Muralidharan, Satyanarayana Polapala Jan 2010

Aphrodisiac Activity And Curative Effects Of Pedalium Murex (L) Against Ethanol Induced Infertility In Male Rats, Gunasekaran Balamurugan, P. Muralidharan, Satyanarayana Polapala

Turkish Journal of Biology

It has been suggested that chronic ethanol exposure may result in testicular damage and infertility in males. Petroleum ether extract of Pedalium murex, family Pedaliaceae (PEPM), is evaluated in this study for its ability to increase aphrodisiac activity and to cure ethanol induced germ cell damage and infertility in male rat models. Doses of 200 and 400 mg/kg of PEPM showed a significant increase (P < 0.01, P < 0.001) in mating and mounting behaviour. The effect on fertility factors such as total body weight, percentage of pregnancy, litter size were also significantly increased (P < 0.01) in comparison with the ethanol-treated group. Significant increases in sperm motility and count were observed in PEPM-treated groups in a dose-dependent manner (P < 0.01; P < 0.001) as compared with the ethanol-treated group. Similarly, reductions in the percentage of abnormal sperm were noted in animals treated with PEPM 400 mg/kg. The effects of PEPM on total protein, total cholesterol and testosterone were satisfactory, the levels being increased significantly for protein (P < 0.05), cholesterol (P < 0.01) and testosterone (P < 0.05) by 400 mg/kg PEPM. Microtome sections of the testes of animals treated with 400 mg/kg PEPM exhibited restoration and recovery of germinal cells and the luminal spermatozoa and were comparable with the control group animals. These effects of PEPM make this natural herb ideal as an aphrodisiac and a potent fertility enhancing drug.

Ultrastructural Changes In Rat Liver By Methyleugenol And Evaluation Of Some Biochemical Parameters, Ayşegül Çerkezkayabeki̇r, Gülnur Kizilay, Fi̇gen Ertan Jan 2010

Ultrastructural Changes In Rat Liver By Methyleugenol And Evaluation Of Some Biochemical Parameters, Ayşegül Çerkezkayabeki̇r, Gülnur Kizilay, Fi̇gen Ertan

Turkish Journal of Biology

The present study investigated the effect of methyleugenol, a food flavoring and fragrance agent, on the livers of laboratory rats. Doses of 10 and 30 mg/kg/day of methyleugenol (in 0.5% methylcellulose) were administered intragastrically (IG) to 2 dose groups for 10 days alongside a control group (n = 10 for each group). Gains in body weight were not statistically significant for either dose. Lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activities decreased (P < 0.05) for both dose groups, but AST (aspartate aminotransferase) activity decreased significantly (P < 0.05) only in the 30 mg/kg/day methyleugenol dose group. Alanine aminotransferase (ALT) activity did not change significantly in either group. The total amount of glucose remained unchanged, but glycogen in the liver decreased significantly (P < 0.05) in the 30 mg/kg/day methyleugenol dose group. There was also an increase of swelling in the smooth endoplasmic reticulum sacs (sER), electron dense accumulations in the sER, cytoplasmic vacuolization, a slight increase of mitochondria and lysosomes, and invaginations in the nucleus membranes of hepatocytes. Extensions in bile canaliculi and increasing microvilli of bile canaliculi in the liver were also observed. These findings indicate the ultrastructural toxic effect of methyleugenol on rat livers in 10 and 30 mg/kg/day doses. Therefore, we may speculate that the toxic effect of methyleugenol needs to be examined in detail.

Conception Rates For Standing Estrus And Fixed-Time Insemination In Dairy Heifers Synchronized With Gnrh And Pgf_{2\Alpha}, Samir Z. El-Zarkouny

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effectiveness of GnRH PGF-based protocols on reproductive outcome in Holstein heifers. Heifers were randomly assigned to the control group (n = 14), or treatment groups (n = 50) treated with GnRH (day -7) and PGF_{2\alpha} (day 0). Heifers that exhibited estrus were inseminated (Select Synch, n = 34) and heifers that did not exhibit estrus up to 48 h after PGF_{2\alpha} injection received a second GnRH injection and were fixed-time inseminated (Ovsynch, n = 16). Conception rates were 40%, 55.9%, and 31.3%, and overall pregnancy rates (P < 0.05) were 64.3%, 97%, and 87.5% in the control, Select Synch, and Ovsynch groups, respectively. Ovsynch heifers had 1.8 ± 0.5 and 3.2 ± 0.6 ng mL^{–1} of serum P4, versus 3.3 ± 0.5 and 3.8 ± 0.6 ng mL–1 in the Select Synch heifers at the time of the first GnRH and PGF_{2\alpha} injection, respectively. Conception rates were 55.6% and 58.3% when P4 concentrations were high, and were 50% and 25% when P4 concentrations were low at the time of the first GnRH and PGF_{2\alpha} injection, respectively. Dairy heifers synchronized with GnRH and PGF_{2\alpha} should be inseminated when estrus is observed, and heifers that do not exhibit estrus up to 48 h after PGF_{2\alpha} injection should be given a second GnRH injection and fixed-time inseminated 16-20 h later.

The objective of this study was to determine the influence of all-trans retinoic acid (ATRA) on the cell survival rate and the antioxidant defense system. MARC-145 cells were treated with ATRA after infection with porcine reproductive and respiratory syndrome virus (PRRSV). The cell survival rate, total antioxidant capability (T-AOC), glutathione peroxidase (GSH-P_X) activity, superoxide dismutase (SOD) activity, lactate dehydrogenase (LDH) activity, and glutathione (GSH) content were determined in samples collected from cells incubated with ATRA for 24 or 48 h. The results show that PRRSV …

The maedi-visna virus (MVV) is distributed worldwide and, to date, no epidemiological surveys have been carried out using ELISA testing in Turkey. The aims of this study were as follows: i) to verify the diagnostic performance of a home-made ELISA test (HM-ELISA) using Turkish ovine sera in comparison with other commercially available ELISA tests, and ii) to perform a preliminary epidemiological survey in İstanbul province. The MVV seroprevalence in İstanbul province was 15.3%. Older sheep were 5 times more likely to be positive than younger animals, ewes were 3 times more likely to be positive than rams, and all the …
