Radiological study of primary lung cancer

Abstract

Ðepartment of Radlology , National Medical CenterThe incidece of primary lung cancer is increasing in our country This presentation is an attemot to co rrelate a useful diagnosis with radiological findings of primary lu ng cancer.Histologically proved 210 cases of prima 까 lung cancer during the period of 15 years were reviewed with plain chest films, tomogram , bronchgram and pulmonary angiogram .The results are as follow :1. Mal e to Female sex ratio was 4: 1. Incidence was most cominon in 5th decade as 40%. 4. In mass size: Average diameter of mass was m9st was 5.3cm .Hilar mass was see n in 48 cases. Hilar mass was most frequent finding in small cell Ca. and the peripheral mass in adeno Ca.5. Cavitary lung Ca. was 26 cases (12.4 %) and most cases had relative thick wall and its mean thickness was 3.6mm.6. Coexistence of pulmonary tuberculosis and lung cancer was 22 cases (10.5 %), and most common in epidermoid cell Ca. as 16 cases.7. Other findings include metastsis to Iymphnode, bone and other organ, and pleural effusion.

The structure of 1,7-heptanediamine dihydrobromide at 173 K, C7H18N2.2HBr

“…First, the structure of 1,3-propanediamine dihydrochloride was reinvestigated (Brisson & Brisse, 1982a). We then concentrated on larger counterions, such as bromide and iodide, especially since 1,6-hexanediamine dihydroiodide (Han, 1963) .97 e A -3. The three highest peaks are all within 1.00 to 1.20 A of Br(1).…”
