In-Vitro Effect Of Phthalate Esters On Retinal Aldolase, Syed Nasir Askari, Meena Zaidi, Nafees Ahmed Jan 2006

In-Vitro Effect Of Phthalate Esters On Retinal Aldolase, Syed Nasir Askari, Meena Zaidi, Nafees Ahmed

Turkish Journal of Medical Sciences

Background and Aim: Phthalate esters used in the manufacture of cosmetics, lubricants, medical devices and wood furnishings enter the human system through various routes and accumulate into tissues to a considerable level. Low levels of plasticizer cause infertility, hypospadias and premature puberty, while high doses of esters can damage the liver and lung. Reports on the ocular effects of these compounds are either not available or very scarce. The present study assessed the impact of dimethyl phthalate (DMP), diethyl-phthalate (DEP) and diethyl hexyl-phthalate (DEHP) on bovine retinal aldolase. Materials and Methods: Retinal aldolase activity of 0.1 ml of 1:10 solution …

Turkish Journal of Medical Sciences

Background: Direct association of trace and macro-elements in relation to human disease has been observed in many research studies. In many cases, an alteration in the metabolism of these minerals has been demonstrated. Methods: In this investigation, the hair levels of the trace elements zinc (Zn), copper (Cu), chromium (Cr), iron (Fe), nickel (Ni) and the toxic elements lead (Pb) and cadmium (Cd) were determined in 110 subjects (57 skin- diseased subjects and 53 controls). Samples were analyzed using atomic absorption spectrophotometric methods. Results: Analysis of hair samples revealed significantly lower levels of zinc, iron and copper in skin-diseased patients …

Characterization Of Footrot Bacteria Dichelobacter Nodosus Using Pcr Amplification And Dna Sequence Analysis, Ifakat Tülay Çağatay, Jon G. H. Hickford

Turkish Journal of Veterinary & Animal Sciences

Dichelobacter nodosus is an essential causative agent of footrot in ruminants, particularly in sheep, goats and cattle. In this study, more than 100 footrot samples were collected from 4 different farming regions in New Zealand (NZ). Selective media were chosen and isolation and routine growth conditions were optimized for NZ D. nodosus serotypes. Approximately 1000 primary plates were anaerobically subcultured several times and examined with Gram staining in order to detect single colonies of D. nodosus. Both the variable region and a part of the conserved region of fimbrial subunit gene (fimA) were amplified from bacterial DNA using polymerase chain …

The Seroprevalence Of Coxiellosis In Farmers And Cattle In Erzurum District In Turkey, Şenay Seyi̇toğlu, Zülal Özkurt, Ufuk Di̇nler, Bi̇ray Okumuş

Turkish Journal of Veterinary & Animal Sciences

Coxiellosis is a zoonosis caused by Coxiella burnetii. This study conducted to determine the prevalence of coxiellosis in cattle and farmers in Eastern Turkey. A total of 230 cattle and 92 human sera were collected and tested for antibodies against C. burnetii by a commercial ELISA kit. The antibodies to C. burnetii were detected in 22 (9.56%) cattle and 18 (19.5%) healthy farmers. Seropositivity was found in 12 of 53 (22.6%) cattle with an abortion history, and 10 of 177 (5.6%) cattle without an abortion history (P < 0.05). There was a correlation between animal and human seroprevalence in the same district. It was observed that the seroprevalence of coxiellosis was higher in northern districts (32.4% in farmers and 15.4% in cattle) than in other districts (12.1% in farmers and 6.5% in cattle) both for humans and animals (P < 0.05). Coxiellosis was an important health problem in both humans and cattle, and the disease may cause abortion in cattle in Eastern Turkey.

In Vitro Effects Of Melatonin On Hyaluronidase Activity And Sperm Motility In Bull Semen, Sadetti̇n Tanyildizi, Tanzer Bozkurt, Osman Çi̇ftçi̇, Fati̇h Saki̇n

Turkish Journal of Veterinary & Animal Sciences

The effects of melatonin on hyaluronidase activity of semen and spermatozoa motility of Holstein bulls were investigation in vitro. Semen samples were divided into 5 equal parts and incubated (v/v) with melatonin at the doses of 0.5, 1, 2 and 4 mM for 60 min. Percentages of spermatozoa motility, morphological abnormality and hyaluronidase activity of semen were determined at 5, 10, 15, 20, 30 and 60 min during incubation. Results show that melatonin caused a significant (P < 0.001) decrease in the spermatozoa motility, while causing a significant increase in the hyaluronidase activities of the semen. However, there was no significant difference in the percentages of abnormal spermatozoa when compared with control samples. Doses of 0.5, 1, 2 and 4 mM of melatonin in bull semen decreased the percentage of spermatozoa motility in a time- and dose-dependent manner. The mean percentages of abnormal spermatozoa were not affected by melatonin treatment. However, it caused an increased hyaluronidase activity of bull semen. In conclusion, the existence of melatonin in bull semen has a significant effect on fertilization ability by affecting spermatozoa motility and hyaluronidase activity.

Effects Of Hybrid Type, Stage Of Maturity, And Fermentation Length On Whole Plant Corn Silage Quality, Mehmet Ali̇ Bal

Turkish Journal of Veterinary & Animal Sciences

Two corn hybrids (conventional: CON; silage: SIL) were harvested at early dent (ED), 1/2 milkline (1/2 ML), and black layer (BL) stages of maturity for testing the effects of hybrid, stage of maturity, and length of fermentation on corn silage quality. Tested parameters were pH, DM, CP, and ruminal in situ DM disappearance (ISDMD), respectively. Longer fermentation length caused lower silage pH at 8 (3.97) and 16 (3.93) weeks. While CP content tended to increase with longer fermentation length, it tended to decrease with increasing maturity stage (ED: 8.0%; BL: 7.2%). In situ DM disappearance was 4% higher for the …

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the optimum time of pre-slaughter feed withdrawal for broiler chickens to maintain profitable and hygienic meat production and to determine its effect on the meat yield, microbiological structure of gut content and microbiological quality of the carcass. A total of 100 birds were allocated to 4 identical 2 m^2 pens in a commercial broiler house, each pen housing 25 birds. The feed withdrawal durations were 18 h (group 1), 12 h (group 2), 6 h (group 3) and 0 h (group 4). The percentage live weight loss increased as the feed withdrawal period increased (P < 0.05). The meat yield in group 4 was lower than that in the other groups (P < 0.05). Full gizzard weight in group 1 was lower than that in groups 3 and 4, and group 2 parameters were lower than group 4 parameters (P < 0.05). Salmonella positive carcasses numbered 1 in group 1, 1 in group 2, 0 in group 3 and 2 in group 4. The only significant difference found among the groups was for coliform bacteria. The coliform count in group 1 (7.54 ± 0.100) was significantly different from that in group 2 (7.00 ± 0.159) and group 3 (7.08 ± 0.169) (P < 0.05).

Turkish Journal of Veterinary & Animal Sciences

Follicular development, ovulation and corpora lutea formation in a bitch were monitored daily by ultrasonography using a 8-MHz linear transducer. These findings were compared with vaginal cytology and changes in the peripheral serum concentrations of oestradiol-17\beta and progesterone.
