Clinical and laboratory criteria for assessing the efficacy of Essliver Forte for patients with combined liver and gall bladder pathologies]

As many as 60 patients with combined pathologies (chronic hepatitis (CH) and chronic non-calculous cholecystitis (CNCC)) were examined, and 20 healthy subjects were included in the control group. The efficacy of Essliver Forte for patients with chronic non-calculous cholecystitis combined with chronic hepatitises (both viral hepatitis and steatohepatitis) was assessed on the basis of clinical, biochemical and bacteriological criteria. Essliver Forte was found to improve the clinical and biochemical parameters of the functional liver condition, bile biochemical characteristics and intestinal microbiocenosis in patients with combined pathologies. The positive clinical effect is most evident for patients with chronic non-calculous cholecystitis and chronic steatohepatitis (both alcohol and non-alcohol). Essliver Forte can be recommended for treatment of patients with combined pathologies.     

Classical and anaplastic seminoma: difference in survival

Classical and anaplastic seminoma are traditionally treated with radiation therapy and are said to have the same prognosis. A retrospective study was undertaken of 90 seminoma patients treated with radiation therapy between 1961 and 1985. The classical group consisted of 71 patients of whom 50 had stage I and 21 had stage II disease. The anaplastic group consisted of 19 patients of whom ten had stage I and nine had stage II disease. The median follow-up time was 64 months for the entire group. The 10-year relapse-free survival rate for the classical group was 94% and for the anaplastic group was 70% (P less than .05). For patients with classical stage I disease, the relapse-free actuarial survival rate was 98%; for patients with anaplastic stage I disease, it was 64% (P less than .02). For the classical stage II disease group, the relapse-free actuarial survival rate was 84% and for the anaplastic stage II disease group, 75% (P less than .70). Four patients in the classical group (6%) had relapses; of these, one patient had local recurrence of tumor, and three had distant metastases. In the anaplastic group, four patients (21%) had relapses; two patients had local recurrence of tumor, and two had distant metastases. Therefore the data suggest a difference in survival and relapse rates between classical and anaplastic seminoma.     

Effect of stimulation of the lateral hypothalamus on the correlation of neuron spike activity in the rabbit neocortex

Cross-correlation and autocorrelation histograms were constructed with the aim of studying correlated spike activity of neurons in the visual and sensorimotor regions of both hemispheres of the rabbit brain before and after stimulation of the right and left lateral hypothalamic regions, which generates food-motivated responses. Stimulation of the left hypothalamus produced larger rearrangements in correlated neuron firing than stimulation of the right hypothalamus. Stimulation of the left hypothalamus, unlike that of the right hypothalamus, was followed by significant increases in the numbers of pairs of left hemisphere neocortical neurons with linked activity, and also induced the sequential firing of neurons in a particular defined order: sensorimotor cortex cells fired first, followed by visual cortex neurons after delays of up to 120 msec. It is concluded that cortical interhemisphere asymmetry in conditions of hunger is associated with nonuniform functioning of the right and left lateral hypothalamic regions.

The use of copper-vapor laser radiation on patients with chemical burns of the esophagus via fiber esophagoscopy

Fifty patients with chemical burns of the esophagus were examined fibroesophagoscopically. All of them underwent local endoscopic irradiation by a copper vapour laser. Laser treatment promoted more rapid healing of the esophageal wall. No cicatrization-induced strictures were noted. Adjuvant local laser therapy is believed valid in management of esophageal chemical trauma.     

Pathogenesis of the low cardiac output syndrome in postresuscitation states

Acute hypervolemia induced in experiments on dogs by infusion of dextran, did not produce decompensation of the circulation in animals whose cardiac output was sharply depressed in the postresuscitation period after circulatory arrest lasting 15 min. The increase in the venous return and change in the conditions of the peripheral circulation as a result of dextran administration temporarily increased the central venous pressure, caused a lasting increase in the arterial pressure, cardiac output, stroke volume, work of the left ventricle, and total oxygen consumption by the body, and lowered the peripheral vascular resistance. In model experiments on dogs subjected to isolated compression ischemia of the brain for 20 min, a low cardiac output syndrome also developed.Presented by Academician of the Academy of Medical Sciences of the USSR N.
