[Esophagotracheal fistula as a complication of radiotherapy of lung cancer].

A case report is presented of a patient with lung cancer treated with chemotherapy followed by radiotherapy due to increasing dysphagia. A few months after radioterapy an esophago-tracheal fistula developed, which was diagnosed by a radiological contrast study and esophagofiberoscopy. Post mortem examination did not reveal malignant invasion of the fistula and surrounding tissues. It seems that the fistula was a late complication of radiotherapy.

Carprofen and the therapy of gastroduodenal ulcerations by ranitidine.

The effects of the addition of carprofen (Roche), a new nonsteroidal antiinflammatory agent, to regular 4-5 week ranitidine (300 mg/day) therapy on gastric secretion, serum gastrin level and ulcer healing, have been examined in 15 gastric ulcer (GU) and 60 duodenal ulcer (DU) patients. Carprofen at a therapeutic dose (300 mg/day) was well tolerated by both GU and DU patients and did not give rise to any major adverse effects. In an open trial on 15 GU (all receiving carprofen), complete endoscopic ulcer healing was found in 9 patients after 3 weeks and in 6 others after 5 weeks of treatment. In a double blind, placebo controlled trial on 60 DU (30 receiving carprofen and 30 receiving placebo), complete ulcer healing was seen after 2 weeks in 23 on carprofen and 22 on placebo, and after 4 weeks in all tested patients. Pentagastrin-induced maximal acid secretion examined 24 h after the last dose of treatment was significantly reduced in DU, but not in GU, patients, and was accompanied by a significant rise in plasma gastrin levels. No change in gastric histology was observed in any patient tested. This study provides evidence that carprofen added to antiulcer ranitidine therapy shows excellent gastrointestinal tolerance, and does not interfere with ulcer healing; it is, therefore, recommended in the treatment of arthritic patients with peptic ulcer disease.

Activity of acid and alkaline phosphatase in neutrophils of rats exposed to benzene and treated with selenium.

Cytochemical studies on activity of acid phosphatase (AcP) and alkaline phosphatase (AP) in peripheral blood neutrophils of rats chronically exposed to benzene vapours (1,200 mg/cm3) demonstrated that the exposure results in the increase of AcP and the decrease of the AP activity. The changes noted correlate with the time of exposure and are observed even after 5 months after exposure. The administration of sodium selenate in a dose of 1.0 microgram/kg before exposure prevented the above enzymatic alterations caused by benzene. In contrast, the administration of selenium in a dose of 5.0 microgram/kg only prevented the change of AP activity and caused reactive neutrophilic leukocytosis.

Enzymatic changes in peripheral blood leukocytes in rats in subacute benzene vapours poisoning. II. The activity of neutrophils enzymes.

The activity of some enzymes of neutrophils in peripheral blood of rats in subacute benzene vapour poisoning (an exposure to the concentration of benzene vapour of 27.000 mg/m3, 6 hr daily for 10 consecutive days) was determined cytochemically. Increase in the activity of alkaline phosphatase and decrease in that of acid hydrolases: acid phosphatase, beta-glucuronidase and beta-glucosaminidase were found. The results obtained indicate destructive action of benzene on lysosomes of peripheral blood neutrophils.
