Total And Lipid-Bound Sialic Acid Levels Inactinic Keratosis And Basal Cell Carcinoma, Pervi̇n Vural, Mukaddes Canbaz, Di̇lek Selçuki̇

Turkish Journal of Medical Sciences

Malignant cells have more sialic acid in their cell membrane than normal cells. Many studies have shown that mean values of total sialic acid (TSA) or lipid-bound sialic acid (LSA) were higher in patients with cancer than in normal subjects. Sialic acid levels correlate with stage of disease, tumor burden, degree of metastasis and recurrence of disease. The aim of the present study was to determine the plasma TSA, LSA, total protein (TP) and TSA/TP values in basal cell carcinoma (BCC) and evaluate if they are sensitive markers for malignancy. Plasma TSA and LSA were measured according to the method …

S-Aroylmethyl N, N-Disubstituteddithiocarbamates With Antiparkinson Activity, Rahi̇me Şi̇mşek, Ci̇hat Şafak, Kevser Erol, Kami̇l Vural

Turkish Journal of Medical Sciences

Seven S-aroylmethyl N,N-disubstituted dithiocarbamate derivatives have been synthesized and their effects on oxotremorine induced tremor have been investigated on mice pretreated with the proparkinsonian drug haloperidol. While the compound 1f inhibited oxotremorine-induced tremors at doses of 50 mg/kg and 100 mg/kg levels, compounds 1a, 1c and 1e had this effect at the dose of 100 mg/kg. The compounds 1b, 1d and 1g had no effect on oxotremorine-induced tremors in mice. These results suggest that some of these derivatives have central antimuscarinic effects and antiparkinson activities.
