Turkish Journal of Veterinary & Animal Sciences

The study was conducted at Alata Horticultural Research institute between 1994 and 1996. The aim of the study was to obtain a strong colony by way of supersedure and empty frames, feeding with saccharose syrup and encouraging egg laying of queen bees at the end of summer. According to the results, there were significant differences among treatments in terms of the development of colony population, brood rearing activity and honey yield. Treatments had no significant effect on wax building activity and swarming tendency.

Turkish Journal of Veterinary & Animal Sciences

One hundred pneumonic lungs from calves were examined by an immunoper oxidase technique using avidin-biotin- per oxidase complex method in formalin-fixed, paraffin-embedded sections for Haemophilus somnus. In the histological examination of tissue sections, strong positive reactions against H. somnus were detected in 14% of the lungs. H. somnus antigens were observed at the surface and/or within the epithelial cells, macrophages, necrotic alveolar walls, alveolar -bronchial/br onchiolar exudates, fibrins, distended interlobular septa and perivascular areas. In addition, dense antigen accumulations were detected in the necrotic macrophages and neutrophils.

Evidence That The Neurokinin 1 Receptor Is Expressed In Spinal Neurones Which Do Not Synthesize Nitric Oxide In The Rat, Mümtaz Nazli, Richard Morris

Turkish Journal of Veterinary & Animal Sciences

The co-localization of the distribution of the neurokinin 1 receptor with nitric oxide was investigated in laminae I-II, III- IV, X and in the intermediolateral horn of the spinal cord in thirteen adult rats. Silver-intensified gold and standard immunocytochemical labelling or standard double immunocytochemical labelling were employed in 40µm-thick sections of the spinal cord. There were many NK1 receptor-expressing neurones in the dorsal horn of the spinal cord, but none of these expressed NOS. Although neurones expressing the NK1 receptor and NOS were in close proximity in LX and IML, co-localization of the NK1 receptor and NOS in single neurones …

Effects of immersion chilling on the microbiological quality of poultry carcasses and cross contamination of Salmonella were studied. Levels of aerobic mezophilic bacteria, coliform, Escherichia coli and the incidence of Salmonella were determined prechill and postchill. The level of coliform and E. coli were reduced by immersion chilling (P0.05) but there was an increase in Salmonella incidence in carcasses exiting the immersion chiller indicating that this may be the point of most significant cross contamination in broiler processing plants. Experiments on microbial decontamination of poultry carcasses with lactic acid were performed. The microbial levels of poultry carcasses were reduced significantly …

Preparation Of Phbv Foams And Investigation Oftheir Potential For Drug Release, Di̇lek Şendi̇l, İhsan Gürsel, Vasif Hasirci

Turkish Journal of Medical Sciences

Polymeric foams seem to have potential for use in many research areas such as cell seeding and macromolecule or drug loading. Three factors were studied to evaluate the efficiency of foams as drug carrier and releasing agents. Effect of polymeric properties was examined by using two types of polymers (PHBV 7 and PHBV 22) differing only in their valerate (copolymer) content. The other factor studied was the effect of loading extent on release kinetics and rate. The results showed an unexpected inverse proportionality between drug loading and release rate. They, however, were in accordance with foam physical properties such as …

Turkish Journal of Medical Sciences

TCDD (2,3,7,8-tetrachlorodibenzo -p-dioxin), an addictive substance in cigarettes, has been implicated in the pathogenesis of pancreatic carcinoma. This compound has not been tested previously for carcinogenicity towards the pancreas, although TCDD is a known liver carcinogen. The present study was designed to ascertain whether TCDD may have a promoting effect on the development of precursor pancreatic lesions on the rat exocrine pancreas.

Most current hypotheses regarding the pathophysiologic mechanisms of pregnancy-induced hypertention point to early placental abnormalities. Therefore, we attempted to determine whether serum human chorionic gonadotropin (hCG) levels reflect a different trophoblastic secretory response of preeclampsia. Thirteen pregnant women with severe preeclampsia were matched with twenty-one normotensive pregnant women with singleton pregnancies in the third trimester.
