[Aneurysmatic and occlusive lesions of the aorto-iliac segment in combination with cancer of the lungs and organs of the abdominal cavity].

An analysis of retrospective data has shown that 34 (14.4%) out of 236 patients with aneurysm of the abdominal aorta and iliac arteries and in 62 (5.1%) out of 1214 patients with occlusion or stenosis of these vessels mainly had cancer of the lungs (52%) and stomach (17.7%) with almost similar incidence in both groups. Colorectal cancer (8.3%) and cancer of other organs of the abdominal cavity were detected more rarely. Aneurysmatic (12 patients) and occlusive-stenosing (17 patients) lesions of the aorto-iliac segment were noted in 29 (0.4%) among 6834 patients with lung cancer or organs of the abdominal cavity. There were three subgroups of patients: (1) first cancer was diagnosed, and then aneurysm, stenosis or occlusion of these arteries (12-12.5%); (2) diseases of the arteries and cancer were diagnosed simultaneously (60-62.5%) and (3) first lesions of the arteries and later cancer (24-25%). Two-stage operative interventions for these diseases were made in 30 (31.2%) patients.

[Optimization of conditions for cultivation of the basidiomycete Coriolus hirsutus--producer of extracellular laccase]. / Optimizatsiia uslovii glubinnogo kul'tivirovaniia bazidiomitseta Coriolus hirsutus--produtsenta vnekletochnoi lakkazy.

The effects of various factors on the biosynthesis of extracellular laccase (EC 1.14.18.1) by the basidiomycete Coriolus hirsutus (Wulf.: Fr.) Quel. no. 072 during submerged cultivation were examined. Optimal parameters for cultivation in a fermenter of 10 l were determined: temperature, 28 degrees C; stirrer rotation speed, 160 rpm; and the inoculum volume, 15% of the working volume of the fermenter. The filtrate contained peroxidase, laccase, and phenol oxidase activities and displayed a high thermal stability.
