ABSTRACT
A new fluorescent Cu(II) sensor (L) obtained from the Schiff base of 5,5'-methylene-bis-salicylaldehyde with amidol (2,4-diaminophenol) was synthesized and characterized by FT-IR, MS, (1)H NMR, (13)C NMR techniques. In the presence of pH 6.5 (KHPO4-Na2HPO4) buffer solutions, copper reacted with L to form a stable 2:1 complex. Fluorescence spectroscopic study showed that Schiff base is highly sensitive towards Cu(II) over other metal ions (K(+), Na(+), Al(3+), Ni(2+), Co(2+), Fe(3+), Zn(2+), Pb(2+)) in DMSO/H2O (30%, v/v). The sensor L was successfully applied to the determination of copper in standard reference material. The structural properties and molecular orbitals of the complex formed between L and Cu(2+) ions were also investigated using quantum chemical computations.
ABSTRACT
Hydatid cysts are common in Turkey. Authors have seen 248 cases of lung hydatid cysts; Fifty hydatid cyst of lung had ruptured. Their symptoms and detailed findings are reported. Rupture caused asphyxia in 3, haemoptysis in 20, lung abcess in 16, rupture in pleural cavity in 4 and anaphylactic reaction in one case.

Aspirated foreign bodies are important problems during childhood. Some instances may be fatal. Most of the foreign bodies are removed with use of classic instruments like rigid bronchoscopes and foreign body forceps. But sometimes we fail to remove them, particularly aspirated beads and spherical objects. In this case, a Fogarty catheter is helpful. Although we have had many experiences recently we failed to remove one aspirated foreign body which was a pencil cap. We succeeded in removing this pencil cap with a new technique that is explained in this article. We used a Storz transbronchial aspiration biopsy needle and a cotton-carrier stylet to remove the pencil cap.

The closed rupture of the pericardium without accompanying intrathoracal injuries, is a rare lesion. These cases are diagnosed generally at autopsy. Authors describe a case, successfully treated by operation.

A series of 460 surgically treated cases of hydatid cyst of the lung is presented. Radiologic preoperative diagnosis was made in 90% of the patients. Cystotomy with subsequent capitonnage was performed in 395 cases, wedge resection in 27, lobectomy in 15 and segmental resection in 23 cases. After careful hemostasis, two drains were placed in the thorax and the thoracic cavity was closed. There were three postoperative deaths (0.6%) and two recurrences of cyst (0.4%) during follow-up investigation for periods up to 10 years.
