[Puncture of liver cystic masses and abscesses].

The results of punctional treatment of cavital masses and abscesses of the liver in 58 patients are analysed. In 33 patients sanation was carried out according to traditional method, including local application of broad spectrum antibiotics; in 25 patients the solution of sodium-hypochlorite was used for treatment. Control group consisted of 38 patients, who underwent open surgical procedure.

[Epidemiologic aspects of echinococcosis].

The performed studies showed, that morbidity of the population with echinococcosis substantially varies even within the boundaries of any administrative region and depends on a number of factors. According to climato-geographic conditions it is possible to single out three zones: arid zone (deserts, semi-deserts, salt-marshes) with minimal level of invasion of the population with echinococcosis; zone of semi-deserts and alpines with medium level of invasion; and zone of oases, valleys, middle-mountains and tugays--with high level of invasion. Among the risk group--cattle-breeders--2 subgroups could be singled out: steppe and mountains cattle-breeders, the risk of invasion in the laffer subgroup is substantially higher.

[Method for draining purulent parts of the liver].

Percutaneous draining of purulent cavities in the liver is an effective method for the treatment of pyogenic diseases of the organ. The traditional method, however, has some shortcomings which often lead to serious complications (intraperitoneal hemorrhage, escape of bile, breaking away of the catheter, hypostatic pneumonia, etc). The work deals with the results of treatment of 32 patients with purulent diseases of the liver.

[The surgical procedure in hepatic echinococcosis].

Results of operations on 252 patients with echinococcosis of the liver are analyzed. Closed hydatidectomy was performed in 166 (65.87%) patients, semi-closed one--in 14 (5.

[The stimulation of superoxide formation by human neutrophils under the action of blood serum from echinococcosis patients].

The effect of blood serum of patients with liver echinococcosis on the superoxide production by neutrophils of donors was studied. The patients observed were distributed to 2 groups: 1) those with uncomplicated disease and 2) those with festered cyst. Blood serum of patients with echinococcosis was proved to stimulate superoxide production by donor neutrophils by 107-483% in comparison with donor's serum.
