Elevated plasma homocysteine concentration either in fasting state or after methionine loading is an independent risk factor for vascular disease. The aim of this study was to evaluate the relationship between fasting total homocysteine (tHcy) and post-methionine load tHcy in healthy control subjects and in patients with angiographically defined coronary artery disease (CAD). Methionine loading has been used to investigate impaired methionine metabolism, especially of the trans-sulphuration pathway. We investigated the effect of methionine excess on total plasma homocysteine in 65 control subjects (44 men and 21 women) who attended a polyclinic of Gülhane Military Medical Academy (GMMA) in Ankara. …

Hemodynamic Changes After Aortopulmonary Separation, Ersi̇n Fadillioğlu, M. Kemal Irmak, Murat Yağmurca, Hasan Erdoğan
Turkish Journal of Medical Sciences
The neural crest origin of the aortopulmonary septum has led us to investigate the septum. We designed the present study to assess the hemodynamic changes following aortopulmonary separation in the rat. We freed the ascending aorta from the pulmonary artery by blunt dissection and placed aluminium foil between them in anesthetized, ventilated, open-chest animals and found that the procedure resulted in a slight but significant increase in systolic and diastolic blood pressure and in an insignificant elevation of the heart rate. The hemodynamic deterioration observed after the separation process might be a result of a possible function of the aortopulmonary …

Overexpression of erbB-2 protein is a marker of clinically aggressive behavior in breast cancer patients. In general erbB-2 status is reported on a scale from negative to 3+, depending on staining intensity, if more than 10% of the tumor cells are stained. However, the original definition does not take into account the percentage of stained cells in detail, since all samples score in the same way if they are above the cut-off, established at 10%. In this study, we evaluated the erB-B2 overexpression by immunohistochemistry in 169 patients and evaluated any correlation with the other well known prognostic parameters. We …

Determination Of Alkaline Phosphatase Activity In Patients With Different Zinc Metabolic Disorders, Zine Kechrid, Rabah Kenouz
Determination Of Alkaline Phosphatase Activity In Patients With Different Zinc Metabolic Disorders, Zine Kechrid, Rabah Kenouz
Turkish Journal of Medical Sciences
Our purpose was to investigate the effect of different zinc metabolic disorders on alkaline phosphatase activity. Serum zinc, glucose and alkaline phosphatase activity were studied in 32 patients with liver cirrhosis, 30 with chronic renal failure and 42 with insulin-dependent diabetes mellitus (IDDM) compared to 42 healthy volunteers. Serum glucose concentration was significantly higher (P < 0.001) in IDDM and liver cirrhosis patients (P < 0.05) compared to the controls. Serum zinc concentrations tended to be lower in all different diseases but did not reach statistical significance. Alkaline phosphatase activity was higher in IDDM (P < 0.05) and liver cirrhosis patients (P < 0.01) compared with the controls. No positive correlation between serum zinc and alkaline phosphatase activity was recorded in any disease. In conclusion, the investigated diseases did not affect the level of serum zinc; however, there was an alteration in alkaline phosphatase activity in patients suffering from diabetes and liver cirrhosis. Consequently, this may be attributed to the functional disturbance that occurred in these patients. Finally, zinc concentration did not follow alkaline phosphatase activity as indicated by the weak correlation obtained.

Pathophysiological Significance Of Blood Rheology, Oğuz Keri̇m Başkurt
Pathophysiological Significance Of Blood Rheology, Oğuz Keri̇m Başkurt
Turkish Journal of Medical Sciences
Tissue perfusion is determined by both blood vessel geometry and the rheological properties of blood. Blood is a non-Newtonian fluid, its viscosity being dependent on flow conditions. Blood and plasma viscosities, as well as the rheological properties of blood cells (e.g., deformability and aggregation of red blood cells), are influenced by disease processes and extreme physiological conditions. These rheological parameters may in turn affect the blood flow in vessels, and hence tissue perfusion. Unfortunately it is not always possible to determine if a change in rheological parameters is the cause or the result of a disease process. The hemorheology-tissue perfusion …

Isolation And Identification Of Phenolic Acids In Malaysian Honey With Antibacterial Properties, Almahdi Melad Aljadi, Kamaruddin Mohd Yusoff
Turkish Journal of Medical Sciences
In this study the non-peroxide antibacterial factors in Malaysian honey were isolated and identified. The phenolic components were extracted from two different local floral honeys and their effects on the growth of selected pathogens were examined. A solid-phase extraction procedure was applied for the first time to recover honey phenolics. Identification was carried out via high performance liquid chromatography and gas chromatography analysis. Antibacterial activity was determined via the disc-diffusion and broth dilution assays. The phenolic fractions of gelam and coconut honeys showed potent antibacterial activities. Both honeys contain gallic, caffeic, and benzoic acids. However, gelam honey contains additional phenolic …

Effects Of Acute Hypoxia On Body Substrate Utilisation During Progressively Increasing Work Rate Exercise Tests, Oğuz Özçeli̇k, Hali̇l Doğan, Haluk Keleşti̇mur
Turkish Journal of Medical Sciences
Respiratory quotient (RQ) was used to assess the effectiveness of exercise interventions in shifting substrate utilisation. The body's RQ can be estimated non-invasively from the ratio of CO_2 production to O_2 consumption. In the present study, we examined the effects of acute hypoxia on the substrate utilisation of the body and its non-invasive estimation from ventilatory and pulmonary gas exchange variables during exercise. Eight male subjects performed two progressively increasing work rate exercise tests (15 W/min) until the limit of tolerance: in one test they were breathing room air (normoxia) and in the other 12% O_2 (hypoxia). Ventilatory and pulmonary …
