Pyrolysis of sewage sludge by solid heat carrier.

The experimental study of fast pyrolysis of dried sewage sludge in the retorting system with solid heat carrier was performed. The yield of the main pyrolysis products such as gas, oil, pyrogenic water, and solid residue (pyrolytic char) was measured in the 490-580 °C range. The maximum oil yield in an amount of 38.

[Comparative studies of immunologic characteristics in plasmapheresis and hemosorption in patients with purulent diseases of the lungs and pleura].

The article deals with the comparative characteristics of the changes in immunological indices in 40 patients with non-specific purulent diseases of the lungs and pleura when plasmapheresis and hemosorption were included in the complex of therapeutic measures. The changes were found to be hetero-directional in character: a non-specific effect of immunostimulation in hemosorption, and immunodepression, particularly marked in the first 24 hours, in plasmapheresis. The post-aggressive reaction after plasmapheresis is either absent or delayed significantly, which makes it possible to conduct detoxification in extremely grave conditions of the patients without making the mechanisms of the post-aggressive reaction operative, as observed in performance of hemosorption.

[The effect of injectable leukinferon on the immune reactivity of patients with steroid-dependent bronchial asthma].

The authors provide the results of the treatment with leukinferon for injections of 25 patients with steroid-dependent bronchial asthma. It is the authors' belief that leukinferon for injections may be recommended for introduction into multimodality schedules of the treatment of patients with the above-indicated pathology. The drug is tolerated well, without any phenomena of sensitization, when administered by inhalation in the form of aqueous aerosol in a dose of 10,000 IU/day.

[Pathogenesis of the cytopenia syndrome in patients with cirrhosis of the liver complicated by portal hypertension].

One of the main causes of cytopenia and cellular immunodeficiency in patients with cirrhosis of the liver and portal hypertension is increased portal pressure, which, in turn, induces increased storage of formed elements in the spleen. Shunting operations producing a stable decompressive effect correct cytopenia similar to splenectomy but at the same time are devoid of the menacing postoperative complications characteristic of splenectomy.

[The theophylline test in the evaluation of the state of cellular immunity in children with different clinical courses of systemic lupus erythematosus].

An inverse reaction of T-lymphocytes to theophylline is sometimes observed in children with systemic lupus erythematosus. In this case the disease runs a more benign course and is less resistant to prednisolone therapy. The theophylline test is recommended for the prediction of the disease course.
