Turkish Journal of Veterinary & Animal Sciences

This paper reports an investigation of the effects of acute and chronic carbon tetrachloride intoxications on the histologic structure of the liver and hematological values and electrocardiograms in rabbits. The rabbits were divided into 3 groups of 7. The first group was the control group, the second group was acutely intoxicated and the third group was chronically intoxicated. In the acutely intoxicated group, caryorexsis, along with necrosis was observed in the hepatocyte of the centrolobular area of the liver. In the chronically intoxicated group, connective tissue mass around the V. centralis increased. This increase of connective tissue caused chirrosis. Hematological …

Growth And Mortality Of Mussels ( Mytilus Edulisl.) Reared Inlantern Nets In Loch Kishorn, Scotland, Sedat Karayücel, Ismi̇han Karayücel Jan 1999

Growth And Mortality Of Mussels ( Mytilus Edulisl.) Reared Inlantern Nets In Loch Kishorn, Scotland, Sedat Karayücel, Ismi̇han Karayücel

Turkish Journal of Veterinary & Animal Sciences

One-year old rope grown mussels ( Mytilus edulis L.) were held in experimental lantern nets at 2 m and 6 m depths in Loch Kishorn on the west coast of Scotland. Growth, mortality and shell morphology were monitored from May 1993 to August 1994. Water temperature, salinity, transparency and food availability were also determined. These showed a clear seasonal cycle, in consequence, growth of mussels was relatively rapid from May to November and very slow during the rest of the year. Depth had a insignificant effect on shell length and tissue growth (P>0.05) due to similar environmental factors. Shell …

Turkish Journal of Veterinary & Animal Sciences

The effect of glazing with the solutions contained ascorbic acid (AA), butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), BHT/BHA combination and only water, and storage time on lipid oxidation of chub mackerel were determined during frozen storage at -18°C for 10 months. Glazing with some antioxidants or water of the fish retarded lipid oxidation when compared to control samples during frozen storage. The results of thiobarbituric acid reactive substances (TBARS), peroxide value (PV) and free fatty acids (FFA) as lipid oxidation parameters increased slowly in all the samples glazed with antioxidants as a function of time but they retarded lipid oxidation …

Morphometric Analysis Of The Mandible In German Shepherd Dogs, Vedat Onar, Oya Kahveci̇oğlu, Rifat Mutuş, Hasan Alpak

Turkish Journal of Veterinary & Animal Sciences

The mandibles of thirty-five German shepherd dogs without skeletal disorders were measured morphometrically. The length and the angle of the mandibles were measured and the correlation was determined between the female and male dogs. Mandible measurements increased with the age of the animals. In males, the value of the 1A and 2A angle was not statistically significant when considering age. In females, a decrease in the 1A and 5A angles was determined while no statistically significant value was determined in 2A, 3A and 4A with age. In conclusion, morphological observations and the results of the measurements have shown that German …

Nuclear Receptor Co-Repressor Gene Localizes To 17p11.2, A Frequently Deleted Band In Malignant Disorders, Michael W. Stacey, Jianxiang Wang, Rebecca L. Byrd, Johnson M. Liu, William G. Kearns Jan 1999

Nuclear Receptor Co-Repressor Gene Localizes To 17p11.2, A Frequently Deleted Band In Malignant Disorders, Michael W. Stacey, Jianxiang Wang, Rebecca L. Byrd, Johnson M. Liu, William G. Kearns

Bioelectrics Publications

The t(8;21) between the AML1 and ETO genes is a commonly seen genetic alteration in acute myeloid leukemia. Recently, we reported that the fusion partner ETO binds to the human nuclear receptor co-repressor (NCOR), a member of the NCOR/SIN3/histone deacetylase complex. This complex mediates transcriptional repression as a result of chromatin remodeling. Here, we used a combination of fluorescence in situ hybridization and hybrid panels to localize the human NCOR gene (NCOR) to chromosome band 17p11.2. The position of human NCOR on 17p11 raises the possibility of deranged transcriptional regulation in malignant disorders associated with deletions of 17p.

Inhibition Of Cpla2-Mediated Arachidonic Acid Release By Cyclic Amp Defines A Negative Feedback Loop For P2y-Receptor Activation In Mdck-D1 Cells, Mingzhao Xing, Steven Post, Rennolds S. Ostrom, Michael Samardzija, Paul A. Insel Jan 1999

Inhibition Of Cpla2-Mediated Arachidonic Acid Release By Cyclic Amp Defines A Negative Feedback Loop For P2y-Receptor Activation In Mdck-D1 Cells, Mingzhao Xing, Steven Post, Rennolds S. Ostrom, Michael Samardzija, Paul A. Insel

Pharmacy Faculty Articles and Research

In Madin-Darby canine kidney D1cells extracellular nucleotides activate P2Y receptors that couple to several signal transduction pathways, including stimulation of multiple phospholipases and adenylyl cyclase. For one class of P2Y receptors, P2Y2 receptors, this stimulation of adenylyl cyclase and increase in cAMP occurs via the conversion of phospholipase A2 (PLA2)-generated arachidonic acid (AA) to prostaglandins (e.g. PGE2). These prostaglandins then stimulate adenylyl cyclase activity, presumably via activation of prostanoid receptors. In the current study we show that agents that increase cellular cAMP levels (including PGE2, forskolin, and the β-adrenergic agonist isoproterenol) can inhibit P2Y receptor-promoted AA release. The protein kinase …

This study aimed to investigate relationships between steroidogenic characteristics and abilities, and some macroscopic characteristics of bovine ovarian follicles and to relate this criterion to the physiological status of the follicles. Follicular fluid of 5 to 8 mm diameter follicles from bovine ovaries (n=46) were analysed and steroidogenic activities of granulosa cells were studied. For the macroscopic classification of the follicles (n=232), appearence of the follicles, thecal vascularization, the colour of theca interna and the presence of follicular debri were determined. Follicles were classified as non-atretic, intermediate and atretic using the cri-terion above. Oestradiol-17b concenration was higher than progesterone concentration …

Survey Of Diseases In Wild Turkeys In Arkansas, Wayne E. Thogmartin, James E. Johnson, Bradley A. Schaeffer, Camille C. Ciriano

Journal of the Arkansas Academy of Science

Nineteen dead wild turkeys were necropsied and 573 live wild turkeys were physically examined for pathological agents in Arkansas between 1992 and 1997 to determine the proximate role disease may play in declining wild populations in Arkansas. Necropsy of the dead wild turkeys identified avian pox and histomoniasis as the most common diseases (16% and 11% of necropsies, respectively). Avian pox was recorded from three major physiographic regions in the state (Ozark Highlands, Ouachita Mountains, Gulf Coastal Plain). One hen died of non-accidental crop impaction, the fifth occurrence observed in the southeastern United States. Another hen died after developing severe, …

Field Sampling And Necropsy Examination Of Fish, A. S. Kane, A. Baya, R. Reimschuessel, K. M. St. Pé, C. A. Poukish, C. P. Driscoll

Virginia Journal of Science

This paper presents an overview of observational and fish sampling tech­niques for investigating fish lesions, morbidity and mortality. These sam­pling techniques and investigations are much like detective work and require attention to detail, common sense, technical proficiency and experience. To solve the mystery of a fish kill, the investigator must use available evidence and clues to piece together a series of events that often have long since passed. The cause of these field events may be chemical, biological or physical; more often, it is some combination of these. An initial categorization approach may be used to reduce the great number …

Virginia's Pfiesteria Monitoring Program: Water Quality, Roger K. Everton, Wick T. Harlan, Jonathan W. Priest, Mark S. Alling

Virginia Journal of Science

During the summer and early fall of 1998, 34 estuarine stations in Virginia were sampled for Pfiesteria like organisms (PLOs) and associated water quality conditions. Stations were sampled either bimonthly (20 stations) or monthly (14 stations) from June to October 1998. At each station, a set of live and Lugol' s preserved samples were collected for presumptive counts of PLOs and water quality conditions were determined. Water quality parame­ters measured included standard field parameters, nutrients (total, dissolved, and particulate), chlorophyll a, and conventional water quality indicators. Although PLOs were relatively low in 1998 as compared to 1997, presump­tive PLO counts …
