[The use of the natural mineral saponite for water decontamination]. / Vykorystannia pryrodnoho mineralu saponitu dlia znezarazhennia vody.

Sorption properties were studied of natural and activated specimens of saponite with respect to poliomyelitis virus, Coxsackie B 1 and B 6 viruses as well as to Enterobacteriaceae group bacteria. With the purpose of comparing the processes of sorption of microorganisms, other minerals were also used, such as bentonite, alunite, glauconite, ceolite. The natural saponite adsorptive properties were found out to undergo changes during the process of thermoactivation. Mechanisms are discussed of a decontaminating effect of thermoactivated saponite in water.

[A new sorbent for the treatment of intestinal infections]. / Novyi sorbent dlia likuvannia kyshkovykh infektsii.

A new inorganic sorbent is proposed endowed with high adsorption-chemical activity towards microorganisms. Animal studies showed that the preparation "Evirhip" is superior to coal-based sorbents (KAY and CKN) and polymethilsiloxan (PMS) towards pathogenic microorganisms, PMS having relatively higher adhesive activity towards Salmonellas than coal-based sorbents.

[A new sorbent for concentrating viruses from an aqueous medium]. / Novyi sorbent dlia kontsentratsiï virusiv iz vodnoho seredovyshcha.

Sorption activity was studied of a naturally occurring dispersive mineral saponite towards certain representatives of the families of Picornaviridae and Reoviridae: poliomyelitis type II viruses, Coxsackie B 1 and B 6, monkey disease rotavirus. In increasing rank order in respect of specific sorption activity is naturally occurring bentonite--sodium form of bentonite--naturally occurring saponite. Possible mechanisms of sorption of viruses on the sorbent's surface, related to structural and chemical properties of the mineral are discussed.

[The sodium form of sudamate--a new low-toxicity antimicrobial preparation]. / Natriieva forma sudamata--novyi nyz'kotoksychnyi antymikrobnvi preparat.

A new low-toxic antimicrobial preparation is proposed to impregnate woven materials used in treatment of pyo-inflammatory wounds contaminated with Gram-positive and Gram-negative bacteria as well as with pathogenic fungi as a result of an artificial infection. Sodic form of sudamate is less toxic, its bactericidal effect being 3-5 times more effective than that of hexachlorophene.

[The inorganic sorbent Evirkhip for water decontamination]. / Neorhanichnyi sorbent "Evirkhip" dlia znezarazhuvannia vody.

Inorganic synthetic sorbent "Evirhip" is recommended for eliminating of contaminants from water with varying degree of pollution. Comparative evaluation was carried out of the activities of the synthetic sorbent, natural dispersive minerals and activated charcoals with their surfaces being variously modified, using a model of typical representatives of intestinal microorganisms (Shigella sonnei, poliomyelitis type II, Sabin strain, viruses). Under stationary conditions of interaction of 1% sorbent "Evirhip" with Shigella sonnei sterilizing effect begins to reveal itself within 60 minutes. Decrease in infectivity of poliovirus occurs by one logarithm of the original level during 30 minutes contact. The paper discusses changes of cationic composition of water as a result of treating it by the sorbent, and feasibility of practical application of the sorbent in processes removing etiological agents of the intestinal infections from drinking, natural and waste water.

[A new sorbent used for preparing the intestines for a surgical intervention]. / Novyi sorbent, zastosovannyi dlia pidhotovky kyshechnyka do operatyvnoho vtruchannia.

A new sorbent with a high sorptive capacity and antimicrobial properties against different species of microorganisms (aerobic and anaerobic) is suggested. Its effectiveness has been proved both in vitro and in vivo. The authors consider that the sorbent can be recommended for clinical trials with the aim of its use in preparation of the intestine for the operation.

[The determination of the antiviral activity of the sorbent Evirkhip (in vitro studies)]. / Vyznachennia protyvirusnoï aktyvnosti sorbenta "Evirkhip" (doslidy in vitro).

It was found that "Evirkhip" possesses a marked antiviral activity confirmed on a model of enteroviruses (coxsackie). The authors also studied the resistance to the drug in the chain: eukaryotic cell-viral particle-prokaryotic cell. The resistance decreased with the shift to right.
