[Clinical characteristics and genetic profile of complement system in renal thrombotic microangiopathy in patients with severe forms of arterial hypertension].

Background: The spectrum of diseases characterized by the development of renal thrombotic microangiopathy (TMA) encompasses the malignant hypertension (MHT). TMA in MHT has conventionally been regarded as a variation of secondary TMA, the treatment of which is restricted to the stabilization of blood pressure levels, a measure that frequently fails to prevent the rapid progression to end-stage renal disease in patients. Nevertheless, there exists a rationale to suggest that, in certain instances, endothelial damage in MHT might be rooted in the dysregulation of the complement system (CS), thereby presenting potential opportunities for the implementation of complement-blocking therapy.

[Possibilities of the ultrasonic method of examination in identifying large lesions of the abdominal cavity and small pelvis organs].

Analysis was made of 13201 ultrasonic studies (USS) of abdominal and small pelvic organs in 5500 patients admitted to the therapeutic department of the multiple-discipline hospital to identify sizable injuries. As many as 176 sizable injuries to the liver, kidneys, gallbladder, pancreas, retroperitoneal space and other organs were recognized. Of these, 52 injuries appeared malignant.

[Use of corrosion inhibitors during the sterilization and disinfection of medical instruments].

The search of corrosion inhibitors reducing the corrosive action of the sterilizing and disinfecting media has been performed in order to protect instruments made of metals against corrosion during these processes. The program of the investigations includes potentiodynamic and potentiostatic measurements and full-scale tests. The infection of the sodium benzoate or potassium gluconate into the disinfecting chloramine solution and sterilizing hydrogene peroxide solution has been shown to improve the resistance to the corrosion for medical instruments made of carbon steel.
