Intralymphnode injection of human monocyte macrophage colony stimulating factor (CSF-1) as a method of obtaining high titer anti-CSF-1 antibodies.

We describe a rabbit intralymphnode immunization technique for obtaining a high titer antihuman CSF-1 antiserum with small amounts of antigen. This procedure provided a rapid (42 days after primo-injection), stable maximum immune response with a high titer antiserum precipitating 30% of 125I CSF-1 at a 1:25.000 dilution. The specificity of the immune serum was assessed by competitive binding experiments in RIA and neutralization of the CSF-1 biological activity in culture. The antiserum was also tested for its ability to detect CSF-1 in Western blotting, immunocytochemistry and immunohisto-chemistry. The results show that the immune serum specifically recognizes the biological active domain of human CSF-1 molecules from different origins and only detects dimeric forms. The potential uses of this anti CSF-1 antiserum are discussed.

[Endolymphatic therapy of children with chronic osteomyelitis of the long tubular bones].

A study was made of the clinical efficacy and immune status in 40 children with chronic osteomyelitis of long tubular bones. Of these, 13 patients received antibiotics endolymphatically and 27 patients were given conventional antibiotic therapy (intramuscularly, intravenously). In view of the predominance of the staphylococcal flora, endolymphatic therapy included the use of gentamycin and lincomycin, the treatment course lasted up to 10 days. Endolymphatic antibacterial therapy has been demonstrated to produce a beneficial clinical effect there was a decrease in fever duration, the amount of postoperative complications, and the duration of inpatient treatment. After endolymphatic therapy the patients' blood manifested a more remarkable, as compared to the control group, rise of the absolute count of T lymphocytes, "active" population of T lymphocytes, together with an increase of the functional activity of lymphocytes in blast transformation, and a reduction, to an equal degree, of the neutrophil and monocyte counts, attesting to a decline of antigenic load of phagocytes. In patients who received antibiotics endolymphatically, the general blood analysis showed a decrease of neutrophilia and marked lymphocytosis. All this mirrored the intensity of immunity activation.

[The characteristics of gentamycin distribution when administered endolymphatically in an experiment].

Gentamicin distribution in some tissues of the abdominal cavity one hour after the intralymphovasal and intranodular administration to 32 rabbits was studied. The experiments were performed under conditions of the blocking and external drainage of the thoracic lymphatic duct. It was found that the optimal bacteriostatic concentrations were reached at both intralymphovasal and intranodular administration.

[The functional morphology of the regional inguinal lymph nodes during the endolymphatic antibiotic therapy of patients with vascular diseases of the lower extremities].

The general structure and cell composition of the inguinal lymph nodes has been analysed at a direct endolymphatic antibiotic therapy, performed with the aim of prophylaxis of suppurative complications, when surgical interventions are performed in the vessels of the lower extremities. Morphokinetics of the lymph nodes depends on duration of the endolymphatic therapy. During early terms it reflects an increase in transport function of the regional inguinal lymph nodes, during late terms it reflects an increase in their immune role. In the lymph nodes, situating on the contralateral side, an analogous reaction is revealed; this appears to demonstrate presence of well developed collaterals between lymph vessels of the lower extremities.

[Effect of endolymphatic antibiotic therapy on the status of cellular immunity in peritonitis].

The immune status in 68 patients with diffuse and generalized peritonitis was studied. It was established, that a degree of the impairment in immune response depended on peritonitis spreading. Endolymphatic antibiotic therapy had immunostimulating effect in patients with diffuse peritonitis, in generalized peritonitis, this was not observed. In patients with generalized peritonitis, it is necessary to include into the complex of treatment the other methods of immunologic correction.

[Hemosorption and endolymphatic therapy in the treatment of paralytic ileus in peritonitis and acute intestinal obstruction].

Hemosorption and endolymphatic pharmacotherapy was included in the complex of treatment in 65 patients operated upon for spreaded forms of peritonitis and acute ileus. Hemosorption was performed within 12-24 h after operation, pharmacological agents (Aceclidine++, Cerucal, Obsidan) were introduced by antegrade endolymphatic infusions 4-6 h after hemosorption. The investigations have shown that in this case there rapidly appears intestinal peristalsis which is maintained not less than for 10-12 hours and in great part of patients it was completely recovered. Multiple stimulations by traditional methods were necessary in the control group to restore peristalsis. The combination of hemosorption and endolymphatic therapy may be recommended as an effective complex for the struggle against intestinal paresis in peritonitis and acute ileus in the postoperative period.

[Primary controlled endolymphatic antibiotic therapy in traumatology and orthopedics].

The work analyses 55 cases of traumatic osteomyelitis of the leg bones, open fractures of the leg bones, and medial fractures of the femoral neck. Patients with medial fractures of the neck of the femur were treated by endoprosthesis after Mur-Kaplan. Endolymphatic antibiotic therapy was included in the complex of therapeutic measures in each group of patients. This method allowed suppuration of the postoperative wounds to be avoided and promoted in this manner rehabilitation of the patients.

[Lymphography and the possibility of tumor cell dissemination].

It is concluded that endolymphatic infusion of X-ray contrast substance in the presence of migrating tumor cells in lymphatic routes is inherent in a potential danger of tumor dissemination. Although getting of tumor cells in blood does not always result in metastases, nevertheless, a due account should be taken of the fact that lymphography is frequently performed in poor immunological resistance patients, preliminarily subjected to chemo- and radiotherapy. The decrease of immune resistance of the organism, in which the lymphatic system is of primary importance, is known to contribute per se to generalization of the tumor process. Another important conclusion is that the principal mass of tumor cells is ejected in the immediate period after endolymphatic injection of X-ray contrast substance. Thus, the cannulation of the thoracic duct during this period may prevent or reduce getting of massive amounts of tumor cells into the total blood flow.

[Rational method of obtaining sera with a high titre of virus-neutralizing antibodies. Report 2].

In addition to report I (ZHMEI, 1977, No. 1) a study was made of 9 more schemes of rabbit immunization with the poliomyelitis virus, type I, for the purpose of obtaining the neutralizing sera of high titre. Vitamins A and C were used in the experiments in the capacity of the activators of the organism reaction; Freund's adjuvant of different make was tested; different reimmunization periods and different amounts of the adjuvant were administered. Titration of rabbit sera in the process of immunization and reimmunization showed immunization into the lymph nodes with the subsequent single reimmunization in one month to be the most effective and economical method of obtaining high effective sera.

[Lymphotropic chemotherapy of patients with tuberculosis of the lymph nodes, skin and abdominal organs].

Experience gained as a result of indirect endolymphatic chemotherapy of patients with tuberculosis of the skin, peripheral and mesenteric lymph nodes is presented. The above treatment is tolerated well by the patients and causes no local or general complications. The clinical effect is achieved 1-3 months earlier than with a traditional therapy which provides a significant drop in the inpatient period and the drug load. Incidence of exacerbations also becomes less. It is worthwhile to include lymphotropic chemotherapy into a complex of therapeutic measures both at the beginning of the treatment and in a torpid course of the disease.

Perilymphatic injections of cytokines: a new tool in active cancer immunotherapy. Experimental rationale and clinical findings.

Various strategies for local immunotherapy performed by using lymphokines and lymphocytes are presented. In experimental mice models, the antitumor reaction elicited through the injection of little amounts of IL-2 and gamma-IFN at the tumor growth site is significantly enhanced by the concurrence of lymphocytes from tumor bearing mice artificially admixed to challenging tumor cells. These lymphocytes act as initiator or helper cells that elicit both a local and a systemic long lasting immune reaction by the release of additional lymphokines. The reaction activated mostly involves draining lymph nodes, where multiple reaction mechanisms are induced. The local injection of cocktails of molecularly defined lymphokines can also mimic the helper action of lymphocytes and trigger a similarly effective anti-tumor reaction. A set of pilot clinical trials with IL-2 or gamma-IFN injected perilymphatically were initiated in patients with advanced primary or recurrent localized tumors of the head and neck and the bladder. This treatment appears to elicit a local reaction by activating a few pathways of patients immunoreactivity, whose efficiency may well be high, as shown by the tumor inhibition often observed.
