[Pathogenesis of multiple sclerosis. Antibody dependent cytotoxicity of lymphocytes against myelin basic proteins in multiple sclerosis].

In 79 of 100 patients with multiple sclerosis, serum antibodies of the IgG type were demonstrated which render normal lymphocytes cytotoxic against basic protein of myelin. In 11 cerebrospinal fluids which were tested the antibody was also found. The method used was the release of 51Cr from chicken erythrocytes coated with antigen. The antibody-dependent lymphocyte cytotoxicity is related to the degree of activity of the disease and not to the evolution of the disease or its course. As the disease worsens, the frequency of positive reactions is higher than in inactive stages. The immunological reaction is very specific for multiple sclerosis, in patients with other neurological disorders only 5% had positive findings. The antibody-dependent cytotoxicity of lymphocytes against basic protein of myelin may be attributed with a certain diagnostic significance. The reaction seems suitable for the supervision of the course of multiple sclerosis and to check the effect of therapeutic measures. The antibody-dependent lymphocyte cytotoxicity against basic protein of myelin is considered to be significant in the pathogenesis of multiple sclerosis.

[Therapy of herpes zoster through active premunization. 2. Treatment of zoster patients, results of experimental and clinical studies, treatment results].

A brief review of the previous and generally inadequate methods for the treatment of Herpes Zoster is presented. The concept of "active premunization" by appropriate inducer to provide an objective treatment is defined. A "Premunization Inducer" (PIND) based on a particular non-infectious preparation of an avian pox ("avipox") virus has been shown to enhance non-specific defence mechanisms in the host by T-cell stimulation and to inhibit virus proliferation by the induction of Interferon. The mode of action, efficacy against different viruses and the safety of the preparation is described and discussed. 114 patients with Herpes Zoster were treated with this "premunization Inducer" either orally (for buccal absorption) or by means of a nasal spray. There were no side effects and in all cases there was a marked reduction in the duration of the illness up to the shedding of the last scab (about 15 days instead of the more usual 31 days). Pain was relieved in some cases within 6 hours and in the remainder within 2 days: a rapid resolution of the inflammation could be observed. There were practically no signs of postherpetic neurological complications among the patients treated (the usual incidence of post-herpetic neuritis is around 18%). The treatment of Herpes I and Herpes II infection other viral conditions will be reported elsewhere.

[The development of vaccination as demonstrated on the development of the Bavarian State Vaccination Institute in the 19th and 20th centuries].

In 1801 the smallpox vaccination has been introduced in Bavaria by order of the Duke Franz Joseph. He appointed a Medical Superintendent, responsible for smallpox vaccinations for the whole country. This was the hour of birth for the Institute, too. The Institute developed quickly to a point of crystallization in the field of prophylactic medicine, research on infectious diseases and social pediatrics. By this Institute the "Retrovaccine" against smallpox was introduced 1856. 1967 -- 1976 an attenuated life smallpox-vaccine (MVA) has been developed. Some years ago the activities of the Institute had been focussed into research of complications after vaccinations and up to date, on the pathogenesis of Multiple Sclerosis. A historical review demonstrates the development of the Institute in the past up to modern activities in research, teaching students and postgraduate education and in medical practice.

[The pathogenesis of multiple sclerosis. Cytotoxic antibodies against myelin sheath tissue in multiple sclerosis].

Cytotoxic antibodies to myelin can be demonstrated by the method of 51Cr-release from chick erythrocytes coated with myelin basic protein. The cytotoxic antibody is inactivated by heating to 56 degrees C and needs complement in order to exert its action. The antibody was determined as IgM and IgG. It has relative specifity and shows cross-reaction with other basic proteins. The cytotoxic antibody was found in only 8% of healthy persons. Patients with multiple sclerosis were positive in 87% of the cases and in acute cases in 94%. In other neurological diseases cytotoxic antibody was present in 64%. The occurrence of cytotoxic antibody to myelin protein is not specific for a particular neurological disorder, especially not for multiple sclerosis. Cytotoxic antibodies arise as a secondary phenomenon, they are not the cause of the disease involved. They appear to be suitable, however, to determine, in association with cellular immunological reactions against myelin which may be regarded as the "primary" immunological processes, the demyelination process in the multiple sclerosis focus.

[Cellular immunity in poxvirus infections. Demonstration, significance and cellular cross reactivity with brain matter].

Its proof, significance, and the cellular cross reactivity to basic encephalitogenic protein of vaccinia-stimulated T-cells. Vaccination against smallpox induces both, a cellular allergy and immunity, and the production of humoral antibodies. Of greater importance for the defense of the organism against infections by orthopox viruses is the cellular immunity. New methods for the proof of cellular immunity and an in vitro-technique for its examination by challange with variola vera virus are described. In close connection with induction of cellular allergy by vaccination an immunological cell-bound reactivity of isolated lymphocytes develops against the basic encephalitogenic protein. In this antigen-stimulated resp.-irritated stage isolated lymphocytes show an enhanced rate of chromosomal aberrations and a high rate of spontaneous transformations. Lymphocytes of patients with Multiple Sclerosis demonstrate a high stimulation rate (3H- resp. 14C-Thymidine-inlay) after challenge with antigen of vaccinia virus. The T cell-mediated cross reactivity between vaccinia and myelin extracts is discussed as an hypothetic pathogenic factor of CNS complications after primary smallpox vaccination.

[Chronic posttraumatic osteomyelitis. Attempt at oral autovaccine therapy].

18 patients suffering from chronic posttraumatic osteomyelitis were treated by oral autovaccination. 11 patients showed significant improvement of clinical condition. The therapeutic effect was evaluated by a scoring system considering the wound morphology, the bone radiology and the erythrocyte sedimentation rate. The most pronounced clinical improvements were observed in patients with established delayed type hypersensitivity against staphylococci.

[Humoral and cell-mediated immune reactions in chronic posttraumatic osteomyelitis (author's transl)].

The humoral and cell mediated immune response was investigated in 90 patients suffering from chronic posttraumatic osteomyelitis. In 10-20% of the patients the serum IgG and IgM was increased, in 5-10% the levels were decreased. The values were compared with those of a control group of 35 normal healthy volunteers. Of 55 patients with staphylococcal infection only 25 had a positive antistaphylolysin titer. Eleven out of 25 patients with staphylococcal osteomyelitis showed a positive in vitro lymphocyte transformation after stimulation with alpha-staphylolysin (mean transformation rate 5.4 equal to or less than 0.9). The phytohemagglutinin and the pokeweed-mitogen response were normal. A comparison of the immunological reactivity of the patients and the clinical severity of the disease showed that patients with established delayed-type hypersensitivity phenomena suffered a significantly worse clinical course of the disease.

Oral immunization against smallpox.

Attenuated vaccinia strain penetrates the mucous membranes of the oral and pharyngeal cavity; local lesions are not produced, even if high doses of attenuated virus are applied. Attenuated vaccinia virus thus offers the possibility of oral and nasal immunization against smallpox in man. Several groups of monkeys were immunized by the oral and nasal route. The subsequent challenge with virulent smallpox virus resulted in strongly mitigated clinical symptoms as compared to non-immunized controls. In the human, oral immunization with live attenuated virus was affected by the administration of virus-containing tablets. The procedures caused no untoward effect in primary vaccinees. Subsequent skin testing and conventional cutaneous vaccination resulted in accelerated takes, demonstrating successful oral pre-immunization.
