[The systematization of epilepsy remissions].

Problems of systematization of remissions of epileptic seizures and epilepsy are discussed on the basis of clinical examination of 341 epileptic patients with seizures suppressed for many years and international classifications of epilepsy. A classification, developed by the authors, is presented. It reflects stages of regress of the disease in achievement of prolonged (for years) control of seizures. The possibility of drug dependence development in these therapeutic remissions is also taken into consideration.

[Adaptive biocontrol in the system of treating epilepsy patients].

Adjuvant treatment of seizures by means of adaptive bioregulation was developed on the basis of material comprising 53 epileptic patients. The onset of auras or predictors of seizures was the signal to begin self-regulating activity. Method of suppression of paroxysmal epileptic activity in the moment of autogenic submersion of the patient is described. Efficacy of autogenic submersion was controlled by reduction of paroxysmal activity on EEG during EEG-examination in the hospital. The approach proved superior to chemotherapy alone.

[The clinico-psychological diagnosis of the personality changes in the initial period of epilepsy].

The authors present the approach to clinicopsychological diagnosis of personality disorders in initial epilepsy based on clinical evidence on 200 epileptics versus 40 healthy controls. 10 experimental techniques have been used. The comparative analysis of the findings obtained at initial stage of the disease and at late stages (within 3 vs. 10 and more postdiagnosis years, respectively) against relevant characteristics of the controls demonstrated that personality disorders within the initial 3 years of the disease are either minimal or absent and can be identified only by the methods of psychological diagnosis. The latter is important for design of adequate therapy.

Growth-stimulating phase of macrophage response to activation: the phenomenon and its implications for tumour growth and immunotherapy.

The dynamics of growth-stimulating and cytotoxic activity of mouse peritoneal macrophages (PMo) in response to in vivo and in vitro bacillus Calmette-Guérin (BCG) or bestatin treatment was studied. It was shown that BCG and bestatin induce cytotoxicity in PMo, and that after the cytotoxic response strong growth-stimulating activity develops. PMo, rendered cytotoxic in vivo and afterwards cultivated in vitro, displayed the same switch from a cytotoxic to a growth-stimulating phase. These results suggest that the growth-stimulating phase is the obligatory PMo response to biological response modifiers (BRM) at least to BCG and bestatin. The growth rate of tumours, transplanted into mice during the cytotoxic phase of the response to BCG, was suppressed, whereas tumours transplanted during the growth-stimulating phase were stimulated. It appears that the development of a growth-stimulating phase after the cytotoxic phase of response to activation by BRM could be one of the reasons for the limited effectiveness of immunotherapy based on the application of macrophage activators.

[Therapeutic and pharmacological monitoring of individual monotherapy of epilepsy with hexamidine].

The treatment with primidone alone of 53 epileptic patients with generalized tonic-clonic seizures, partial attacks with elementary symptomatology, and partial fits with complex symptomatology removed them completely in 75, 64.2, and 36.9% of the patients, respectively. The number of attacks was decreased as a result by 50% and over in 90, 78.6, and 73.7% of the patients, respectively. The attainment of such high efficacy of the monotherapy (called by the author intensive in contrast to routine or inadequate therapy carried out, as a rule, in standard doses) appeared possible only under the conditions of individualization of the drug doses which ranged within 250-2500 mg/day. The concentration of phenobarbital, the main end metabolite of primidone, in the blood serum of patients, in whom the attacks were completely arrested and who developed no clinical side effects with no toxic action on the internal organs, ranged from 14 to 59.1 mg/l. In partial fits with complex symptomatology, primidone appeared least effective for those types of fits in the treatment of which it was viewed as most adequate.

[Pathogenic role of the endogenous convulsant kynurenine in the mechanisms of development of epileptic attacks in alcoholics].

The role of the endogenous convulsant kynurenine (K) in the mechanisms of the development of epileptic seizures in alcoholic persons was studied on a clinical material of 63 patients suffering from alcoholism with the presence on the EEG of paroxysmal alterations without epileptic fits (n = 28) and alcoholic epilepsy (n = 35), epileptic patients not abusing alcohol (n = 20), and practically healthy subjects (n = 10). There was a significant increase of the K concentration in alcoholic patients with paroxysmal disturbances on the EEG or convulsive seizures. That increase directly correlated with the rate of convulsive epileptic fits. The rise of K in patients with alcoholic epilepsy was lower than in epileptic patients, being, however, significantly higher than in practically healthy subjects abusing alcohol and having but paroxysmal alterations on the EEG (without seizures).

[Improving the organization and increasing the quality of the treatment of patients with epilepsy].

The authors suggest a program of improving health services for patients suffering from epilepsy (the setting up of the Regional Epileptological Centre). The clinical material provided by 1350 patients with epilepsy is analyzed for cost and therapeutic efficacy of the conducted organizational measures. Improvement of the treatment and diagnostic work, upgrading of the patients' examination quality have been demonstrated. The economic efficiency has been computed.

[Effect of modifiers of natural biological response on the functional activity of macrophages (oncological aspect)].

Induction of cytotoxicity by biological response modifiers (BRMs) is only one aspect of macrophage activation. After the use of BRMs there were other changes in the functional activity of cells and in particular their increased production or secretion of a number of growth factors. Thus, activation of macrophage antitumor activity induced by BCG vaccine was transitory while activation of growth factor production was more stable in time which finally led to increased proliferation of tumor cells. Combined use of cyclophosphamide and BCG vaccine significantly increased not only the toxicity induced by BCG vaccine but also their liberation of the growth factors. Such macrophages lost their ability to control the growth of a small number of the tumor cells cultivated in their presence. Development of ways for directed activation of macrophages aimed at elimination of the tumor cells which survived the chemotherapy should include evaluation of the combined effect of various BRMs and chemotherapeutics on both antitumor and protumor activity i. e. ability to produce the factors stimulating the tumor growth.

[Effect of BCG and cyclophosphamide on the antitumor activity of mouse peritoneal macrophages].

Peritoneal macrophages activated by BCG and cyclophosphamide were unable to complete elimination of small numbers of tumour cells in spite of high level of cytotoxicity and cytostatic activity of these cells. It is appeared useful to evaluate the influence of new immunomodulators and combinations of immunomodulators with chemotherapeutic drugs not only on the cytotoxic and cytostatic, but also on the "feeder" activity of macrophages.

[Clinico-electroencephalographic correlations in the process of rehabilitation of patients with epilepsy].

A total of 50 patients with epilepsy underwent an electroencephalographic investigation at the rehabilitation stage during remission. EEG tests established that the discontinuation of epileptic seizures was followed by a stepwise compensatory EEG rearrangement. In patients that had had rare seizures, the EEG normalization was characteristic of the 2 to 3 years-long remissions. With frequent polymorphic seizures, the background activity was normalized in the steady remission of many (5 and more) years duration. The cessation of antiepileptic therapy should be effected under a mandatory EEG control. The absence of negative EEG changes on anticonvulsants discontinuation is a sign of correct treatment paradigm.

Modulation of growth-stimulating and antitumor activity of macrophages by BCG and cyclophosphamide.

Recently it has been shown that some tumours require macrophage-derived growth factors for in vitro and in vivo proliferation, as well as tumour growth stimulation by macrophages. Furthermore, it has been reported that several biological response modifiers (BRM) stimulated some growth factor production in macrophages. In the present study we tried to define whether some BRM can modulate production of macrophage-derived growth factors for stimulating tumour cells. Results obtained indicate that: 1) growth stimulating activity of macrophages may be co-expressed with antitumor activity; 2) growth stimulating activity could prevail over antitumor effects in the outcome of tumour cell/macrophage interaction in vitro; 3) Some BRM and antitumor drugs can modulate the balance between antitumor and growth stimulating activity of macrophages. It is therefore proposed that growth factors modulation assessment is necessary for new BRM characterization.

[Rehabilitation of epileptic patients in an outpatient setting].

The work is devoted to the rehabilitation of epileptic patients under outpatient conditions. On the basis of the data of epidemiologic studies the author considers the specific nature of rehabilitation measures provided to patients on an outpatient basis, describes the drawbacks of drug therapy, and proposes new forms of the organization of specialized cost-effective medical care to patients (a regional epilepsy centre).

[The importance of psychological research in the system of rehabilitating epileptics].

The authors consider the results of the psychological analysis of individual characteristics of intellectual and mnemonic activity, of emotional response, behaviour and the system of relations determined with the help of 10 experimental psychological techniques in 239 epileptic patients with a variable clinical picture of the disease in the process of their rehabilitation. The data obtained by the psychologist are correlated with the assessment of mental disorders by both the patient himself and the doctor. A conclusion is made that the psychological diagnosis is more accurate and its results may be used as an important criterion in the process of rehabilitation of epileptic patients.

[Concentration of benzonal in the blood of epileptic patients at different daily doses and with other anticonvulsants].

A study involving 36 epileptic patients and 8 control subjects was devoted to the optimization of antiepileptic drug therapy with the help of determining the blood levels of anticonvulsants (benzonal, phenobarbital). The daily dose of an anticonvulsant directly correlated with its blood levels. Blood levels of benzonal increased upon the additional administration to patients of hexamidine or hexamidine and diphenylhydantoin mixtures. A reduction in the daily dose of benzonal by 2/3 was attended by a 50% decline in its blood levels.

[Various aspects of the biological basis for rehabilitating epileptics].

Using the clinical data on 270 epileptic patients, the author offers the biological validation of occupational treatment, determines the role of the psychological effects in the system of patients' rehabilitation and validates the significance of the EEG as a method for objective assessment of the degree of the regression of the clinical and subclinical manifestations of epilepsy in the process of biological therapy. It has been established that: 1) psychosocial effects, in particular, the patients' occupational activity help to decrease the frequency of attacks and inhibit the paroxysmal activity on the EEG during an experiment simulating a working process; 2) a long-term (up to 8 years) absence of seizures according to the EEG readings is not always attended with the regression of the subclinical manifestations of epilepsy; 3) the realization of rehabilitation programmes should be evaluated, appart from the duration of the attack-free period, by the EEG readings as well.
