JOURNAL FREE ACCESSSeven hundred-three cases of primary epithelial tumors of the salivary glands diagnosed over a long period in two Turkish University Hospitals are presented. The patient age distribution, sex, and the locations and histological types of the tumors are discussed and compared with those in the literature.View full abstractDownload PDF (775K) -

JOURNAL FREE ACCESSThe effects of SCH23390, a selective D1 receptor antagonist, injected into either the dorsal striatum or nucleus accumbens on methamphetamine-induced stereotyped gnawing and hyperlocomotion in rats were investigated. SCH23390 injected into the dorsal striatum did not alter the gnawing induced by both methamphetamine and apomorphine. However, SCH23390 injected into the nucleus accumbens significantly reduced methamphetamine-induced gnawing without altering the effects of apomorphine. Injection of SCH23390 into the nucleus accumbens reduced the hyperlocomotion produced by methamphetamine more markedly than injection of SCH23390 into the dorsal striatum.View full abstractDownload PDF (733K) -

JOURNAL FREE ACCESSThe crystallographic properties of hydroxyapatites synthesized at temperatures of 200°C, 500°C, 900°C and 1250°C, designated HAP200, HAP500, HAP900 and HAP1250, respectively, were studied using X-ray powder diffraction. Values of a-axis length for the hydroxyapatites ranged from 9.406 Å to 9.416 Å, which were smaller than the corresponding value for stoichimetric hydroxyapatite, a=9.418 Å. Generally, the a-axis length decreased with the synthesis temperature, except for HAP500 which showed the smallest value. Crystallinity of the hydroxyapatites, measured by X-ray diffraction peak broadening as full width at the half-maximum value (FWHM), increased with the synthesis temperature, although HAP500 showed a decrease. These results suggest that the synthetic hydroxyapatites contained some carbonate ions, probably at the A-site of the apatite structure, and that the structure was depleted of carbonate ions at about 500°C.View full abstractDownload PDF (469K) -

JOURNAL FREE ACCESSEleven cases of maxillary osteomyelitis were studied clinically and radiologically. Clinically, the molar area was most affected. The average age of the patients was 47 years and there was no sex difference. Radiologically, the spotty type of osteolytic change was the most frequent, and osteosclerosis was rare. Sequestrum was not a clear feature radiologically. The features of maxillary and mandibular osteomyelitis were compared and the findings discussed.View full abstractDownload PDF (5095K)
