[Humoral link of autoimmune reactions to neuron-specific enolase in post-radiation encephalopathy patients].

The purpose of this research was to study the humoral link of autoimmune response to the brain antigen i.e. neurospecific enolase (NSE) in liquidators of the Chernobyl accident aftereffects diagnosed as having "postradiation encephalopathy" (PREP).

[The influence of bile on the survival of leukocyte in patients with purulent cholangitis].

It was established that while incubation of the blood leucocytes of a healthy person with duodenal bile of a patient, suffering chronical purulent cholangitis, the leucocytes life span enhances. In a patient's bile the leucocytes survival is higher than in healthy person's.

[The level of embryonic antigens in the blood serum and cerebrospinal fluid of neuro-oncological patients].

The levels of embryonic antigens (cancer embryonic antigen, alpha-fetoprotein, beta-chorionic gonadotropin were measured in the serum, spinal fluid, the cystic fluid of tumor 83 of neuro-oncological patients. It was found that the blood concentrations of cancer embryonic antigen and alpha-fetoprotein were not generally related to the degree of malignancy and the blood level of beta-chorionic gonadotropin decreased with the higher degree of tumor anaplasia. The high content of beta-chorionic gonadotropin in the spinal fluid suggests its origin from a brain tumor.

[The effect of a suspension of brain cells from mice of varying age on the growth of tumors, transplanted under the capsule].

Antitumour activity of cerebral cells at different stages of ontogenesis (embryonic, new-born, adult) has been studied. Researches have been carried out at killer-activity patterns in vitro with target-cells and tumour transplantation under mice kidney's capsule in vivo. It has been established that mice cerebral cells' suspension can decrease the tumour transplants' growth under kidney's capsule.

[Clinico-diagnostic value of the immunologic parameters of blood and cerebrospinal fluid in patients with a tumor of the posterior cranial fossa].

In 37 patients with a tumor of the posterior cranial fossa, the immunologic indices of the spinal fluid, blood serum and tumor contents were studied. It was established that changes in the immunologic indices (intrathecal synthesis of IgG and IgA, production of the immunoregulatory factors of cellular immunity, severity of lesion of the brain structures) depended on a degree of tumor anaplasia and age of the patients. These findings can be used for diagnosis of cerebral neoplasms of different degree of malignancy with regard for the age of a patient.

[Changes in the immune status of patients with brain tumors in the pre- and postoperative periods].

Changes of the immune status in patients with glioblastomas and meningiomas during the stages of surgical treatment were studied. Functional activity of lymphocytes suffers to a greater measure in patients in the preoperative period and the ratio of the lymphocyte T- and B-subpopulations changes. Preoperative management including hormonal therapy causes further inhibition of the immune status but has no effect on the degree of neurosensitization of the patients, which may be a risk factor of the development of postoperative complications of infectious-inflammatory neuroallergic etiology.

[The use of myelopid in the combined treatment of infectious-inflammatory complications in the postoperative period in neuro-oncology patients].

Clinical observations over 48 neurosurgical patients with infectious inflammatory complications and study of their immune status showed that a course of immunocorrective therapy with myelopid produces a favourable clinical effect and normalizes the patient's immune status. Myelopid causes the best normalizing effect in patients with nontumorous pathology of the central nervous system and in extracerebral neoplasms.

[Lymphocyte subpopulations and their functional activity in patients with brain tumors].

The authors studied a complex of immunological indices in 69 patients with brain tumours in the pre- and postoperative period. It is shown that in patients with benign brain tumours, preoperative care and surgical intervention largely alter the functional activity of T and B-lymphocytes while patients with malignant tumours of the brain revealed less pronounced changes of quantitative indices of definite subpopulations of lymphocytes against the background of marked reduction of their functional activity. The necessity is emphasized of complex evaluation of immunological indices in patients with brain tumours.

[The modification of the catalytic activity of mitochondrial monoaminoxidase and the suppression of the growth of experimental brain tumors].

A derivative of pyrazinocarbazole the antidepressant pyrazidol, whose inhibition of serotonin deaminase activity of the brain mitochondrial monoamine oxidase is attended by induction of the property of catalysing histamine oxidation, inhibits the growth of glial tumors in experiments. Another derivative of pyrazinocarbazole, which inhibits serotonin deamination but does not induce the appearance of histamine deaminase activity, produces no effect on the growth of glial tumors of the brain.

[The effect of surgical intervention on the state of the immune system in brain tumors].

In patients with benign and malignant brain tumors before the operation, the suppression of the immune system, in particular, proliferative response of lymphocytes to T- and B-mitogens was established. Preoperative preparation of the patients aggravated this process. At day 8-10 after the operation, normalization of the main indices of immunity in patients with benign tumors was noted.

[Correction of immunity disorder developing after craniocerebral trauma].

The article presents some data concerning influence of humoral factor received from blood serum of injured animals on humoral and cell immune response of animals. The results show that administration of humoral factor prevents stress-induced devastation of thymus, improves humoral immune response to antigen test (sheep erythrocytes) and restores hypersensitivity of decelerated type (HDT) reactions. Immune stimulating effects are observed both right after cranial trauma and some time later -- 5-7 days after the injury.

[Humoral and cellular immunity in patients with left- and right-sided intracerebral tumors].

The authors compared the values of the immune status of patients with glial brain tumor of grade III-IV anaplasia in the left and right side in the preoperative period. In patients with the tumor in the right hemisphere, in the frontotemporal region in particular, the absolute number of rosette-forming cells in peripheral blood and the blast-transformation activity of lymphocytes in response to phytohemagglutinin were reduced significantly (p less than 0.05) as compared to the values in patients with the tumor on the left side.

[Efficacy of chemotherapy and immunochemotherapy in neuro-oncologic patients of various blood groups (ABO system)].

The efficacy of postoperative chemo- and immunochemotherapy was analysed according to the survival period from study of the catamnesis of patients who underwent operation for malignant (III-IV degree malignancy) gliomas. In analysing the efficacy of various schedules of combined treatment, the authors took into consideration the patients AB0 blood group because it is known that many antineoplastic antibiotics contain structures which are marked by cross reaction with the ABH isoantigens. The results of the study showed that the use of polychemotherapy and levamisole in neuro-oncological patients with A(II) and AB(IV) blood groups is promising.

[Immunologic status of patients in the late period after cranio-cerebral trauma].

Immune disorders characteristic of the late period of craniocerebral trauma involve T-cellular, regulatory link and were represented by a reduction of T-cells count and function with disbalance in lymphocytes-helpers, increase in macrophagal and lymphoid suppressors activity susceptible to indomethacin++. The changes also include the neurosensibilization of cellular and humoral type to brain-specific++ proteins: OBM, 14-3-2, S-100. Most pronounced changes were detected in patients after severe brain concussion with focal neural changes persisting in the late period.

[Immunomodulating action of myelopeptides in severe closed experimental craniocerebral injury in rats].

An immunocorrective effect of myelopeptides (MP) isolated from pig bone marrow cell culture supernatant in the early posttraumatic period in rats with severe cranial injury has been assessed. MP administration prevented cellular devastation of thymus and bone marrow, as well as spleen hyperplasia. The most marked MP effect was observed within the first 24 h after its administration.
