Öğe Determination of anae and acp-ase positive lymphocytes of peripheral blood and endometrium tissues in experimental hypothyroidism-ınduced rats(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2019) Colakoglu, Fatma; Donmez, Hasan HuseyinThis study was aimed to provide information about the status of the immune system by revealing changes in peripheral blood leukocyte (PBL) percentages, ANAE- and ACP-ase(+) lymphocyte rates in peripheral blood (PB) and endometrium tissues of experimental hypothyroidism-induced rats. In this study, 15 healthy female Wistar Albino rats were used. Rats were fed through 4 weeks. The Group E (experimental, n=9) is group that were made hypothyroidism by intraperitoneal methimazole enjection for 2 weeks. Rats of the Group C (control, n=6) were untreated. In the 2nd and 4th weeks, ANAE- and ACP-ase(+) lymphocyte rates of the Group E were higher than Group C in PB. Excepting eosinophil and basophil leukocyte rates, there was no statistical difference in the other PBL percentages in the both of weeks. In PB, while lymphocyte rate of the 4th week was no statistically different (P>0.05), it was found lower in Group C. There was no alteration in ANAE- and ACP-ase(+) lymphocyte rates of uterine tissue. As a result, whereas hypothyroidism caused significant alterations in PBL and T lymphocyte rates, the any marked changes was not observed in the uterine tissue.Öğe Effects of aflatoxin on AgNOR activity of cells in different regions of kidney, and protective effectiveness of esterified glucomannan in ram(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2013) Colakoglu, Fatma; Donmez, Hasan HuseyinIn this study, the effects of total aflatoxin (AF) given orally on silver-staining nucleolus organizer regions (AgNORs) activity were studied in glomerulus and tubular epithelial cells of kidney in Merino rams. In addition, this study was conducted in order to evaluate the efficacy of an esterified glucomannan (EG) for protection against to aflatoxicosis. As materials, 1 year-old 32 Merino rams were used. Rams were fed through the 92 days. Control group (C) fed with the commercial feed. AF group fed with commercial feed added 250 mu g/day of total AF. EG group fed with commercial feed added 2 g/day of EG daily. AF+EG group fed with commercial feed added 250 mu g/day of total AF and 2 g/day of EG. At the end of the 92nd day the animals were sacrificed, and tissue samples were taken from the kidneys. Whereas ratio of nuclear area of the AgNOR area of cells in examinated regions of kidney was found decreased significantly (P<0.05) in the AF group compared to the control group, AF+EG group was found similar to control group (P>0.05). In conclusion, the adverse effects causing by aflatoxicosis on the kidney AgNOR activity could be ameliorated by adding EG to the ration.Öğe Effects of Aflatoxin on Liver and Protective Effectiveness of Esterified Glucomannan in Merino Rams(HINDAWI LTD, 2012) Colakoglu, Fatma; Donmez, Hasan HuseyinThe effects of total aflatoxin (AF) given orally on liver in Merino rams were studied. In addition, this study was conducted in order to evaluate the efficacy of an esterified glucomannan (EG) for protection against aflatoxicosis. One-year-old 32 Merino rams were divided into four equal groups. The control group (C) was fed with the commercial feed. The AF group was fed with commercial feed plus 250 mu g/day of total AF. The EG group was fed with commercial feed plus 2 g/day of EG. The AF + EG group was fed with commercial feed plus 250 mu g/day of total AF and 2 g/day of EG. After feeding period, tissue samples were taken from the liver in order to perform histological analyses. Vacuolar degeneration with small and large droplets and hydropic degeneration in hepatocytes were observed in the AF group. The ceroid pigmentation was observed in macrophages in groups or one by one. It was observed that the fat rate in hepatocytes was 2.6% in the C group, 35.5% in the AF group, 2.9% in the EG group, and 9.6% in the AF + EG group. In conclusion, the adverse effects caused by aflatoxicosis on the liver could be ameliorated by adding EG to the ration.Öğe Effects of Glucomannan on the Sacculus Rotundus and Peripheral Blood Lymphocytes in New Zealand Rabbits during Aflatoxicosis(HINDAWI LTD, 2012) Sur, Emrah; Donmez, Hasan Huseyin; Boydak, Murat; Ataman, Mehmet BozkurtThis study was aimed to determine the effects of the glucomannan added to aflatoxin- (AF-) contaminated diet on the sacculus rotundus and peripheral blood lymphocytes of New Zealand rabbits by histological and enzyme histochemical methods. Twenty-four adult rabbits of both sexes were divided into four equal groups, namely, as control, glucomannan 0.2 g/day, AF 125 mu g/kg/day, and glucomannan combined with AF. The animals in all groups were treated for 12 weeks by the above-mentioned diet. When compared to control, AF-treatment caused significant decrease in alpha-naphthyl acetate esterase- (ANAE-) positive peripheral blood lymphocyte (PBL) percentages. The addition of the glucomannan to AFcontaining diet recovered the adverse effects of AF on sacculus rotundus and increased the ANAE-positive PBL counts. These results suggested that glucomannan was effective against the negative effects of AF in rabbits.Öğe Protective effect of esterified glucomannan on aflatoxin-induced changes in testicular function, sperm quality, and seminal plasma biochemistry in rams(ELSEVIER SCIENCE INC, 2014) Ataman, Mehmet Bozkurt; Donmez, Hasan Huseyin; Doenmez, Nurcan; Sur, Emrah; Bucak, Mustafa Numan; Coyan, KenanThe aim of this study was to determine the effect of aflatoxin (AF) on spermatologic, biochemical, and testis parameters in rams, and the protective efficiency of esterified glucomannan (EG) co-administered with AF. Thirty-two Merino rams (12-14 months old) were used. The experimental design consisted of four dietary treatments. The control group was fed commercial feed. The AF group was fed with commercial feed plus 250 mu g/d of total AF. The EG group received commercial feed plus 2 g/d of EG. The AF + EG group was given commercial feed plus 250 mu g/d of total AF and 2 g/d of EG. There were treatment, time, and treatment-by-time interaction effects on sperm motility, abnormal spermatozoa, damaged acrosome, and dead spermatozoa (P < 0.01). The percentage of motile sperm was lower and the percentages of abnormal sperm, sperm with damaged acrosomes, and dead sperm were greater in the AF group than in the control, AF+EG, and EG groups, as from week 3 until the end of week 12 (P < 0.05). As from week 3, hyaluronidase activity in the seminal plasma increased significantly in the AF group, compared with the control. The co-administration of AF+EG was found to be effective in preventing the increase in hyaluronidase activity. As week 4, malondialdehyde (MDA) levels were significantly higher in the AF group compared with the control. The combined administration of AF+EG was found to be effective in lowering the MDA levels, increased by AF, to the levels measured in the control (P < 0.05). Although glutathione (GSH) levels were determined to have significantly decreased in the AF group in comparison to the control, it was observed that, in the group co-administered with AF and EG, particularly after week 7, the GSH levels, which had decreased owing to AF, were largely ameliorated (P < 0.05). In conclusion, AF adversely affected spermatologic, biochemical, and testis parameters, and the combined administration of EG with AF reversibly eliminated these adverse effects in rams.
