Preclinical studied of general toxic properties of preparations containing ultralow doses of antibodies to endogenous regulators

Preclinical study of the safety of 6 preparations containing ultralow doses of antibodies to endogenous regulators showed that they are relatively safe, are well tolerated by animals in doses more than 1000-fold surpassing the therapeutic dose for humans, and produce no general toxic effect on the organism of laboratory animals.

Antibodies to calcium-binding S100B protein block the conditioning of long-term sensitization in the terrestrial snail

The effects of antibodies to calcium-binding S100B protein diluted to 10(-12) (LAS100B) on the long-term sensitization in the Helix lucorum snail (neurobiological model of the anxious-depressive state) were evaluated. The administration of LAS100B prior to conditioning of long-term sensitization in the terrestrial snail 10 min prior to the first electric stimulus) prevents strengthening of the defensive reaction of withdrawing the ommatophores (eye tentacles) and the defensive reaction of closing the pneumostome. This effect is termed "protective", as it prevents the conditioning of long-term sensitization. At the same time, snails given an injection of saline developed long-term sensitization with a significant strengthening of the defensive reactions of withdrawing the ommatophores and closing the pneumostome. When LAS100B was administered before long-term sensitization in advance, the membrane and threshold potentials of premotor interneurons, which regulate defensive behaviour, decreased to a significantly lesser extent compared to the long-term sensitization arm. It is possible that the "protective" effect is linked to the mechanisms of maintaining the membrane potential and changes in extra- and intracellular balance of calcium-binding S100B protein.

Improvement of memory by means of ultra-low doses of antibodies to S-100B antigen

Antigen S-100B of nervous tissue, according to the data of numerous studies, affects the mechanisms of nervous system plasticity and memory. The influence of ultralow doses of antibodies to S-100B (6C dilution, according to the homeopathic pharmacopoeia) has been studied on three learning behavioral models on Wistar rats, which were inhibitory avoidance, choosing of bowls with sucrose and feeding behavior cessation after auditory signal. For all three tasks, parameters of reproduction of the learned skills improved after per oral administration of potentiated antibodies to S-100B antigen immediately after learning. Possible mechanisms of the anti-S-100B antibodies influence on memory formation are discussed.

Investigation of changes in NO content during long-term sensitization in edible snail using EPR-spectroscopy: effects of antibodies to calcium-binding protein S-100

EPR-spectroscopy experiments (electron paramagnetic resonance) demonstrated a decrease in NO production in the nervous system and heart of edible snail Helix lucorum after formation of long-term sensitization, a neurobiological model of anxiety and depression. The protective effect of antibodies to Ca(2+)-binding protein S-100 in dilution of 10(-12) on the formation of long-term sensitization was accompanied by partial recovery of NO synthesis in the nervous system and heart. These findings indicate that the imbalance in Ca(2+)-binding protein S-100 can lead to inhibition or modulation of some processes during plastic reorganization in the body and especially during pathological processes.

Release-active antibodies to S100 protein are able to improve the experimental allergic encephalomyelitis

AIM: To reveal the effects of release-active antibodies to S100 protein in an animal model of multiple sclerosis.
MATERIAL AND METHODS: Sixty female Wistar rats, aged 12 weeks, were included in the study. The pathology was induced by subcutaneous injection of the spinal cord homogenate. Afterwards the rats received a water solution of release-active antibodies to S100 protein (2,5 ml/kg/day, tenoten) or distilled water intragastrically during 30 days. Intramuscular injections of glatiramer acetate (4 mg/kg/day, copaxone) were used as a positive control.
RESULTS AND CONCLUSION: Release-active antibodies to S100 protein enhanced the latency period of the disease, reduced its peak intensity and compensated the loss of body weight of the animals. The experimental drug effect was similar to the results of copaxone injections.

Antibodies to S100 proteins have anxiolytic-like activity at ultra-low doses in the adult rat

S100 proteins are small calcium-binding proteins interacting with numerous intra- and extra cellular targets involved in diverse physiological functions. In particular, S100 proteins may be involved in the regulation of anxiety-related behaviour. In the present study, the effects of affinity-purified antibodies to S100 proteins administered orally at ultra-low doses were evaluated in pre-clinical tests for anxiolytic-like activity in the adult rat. In the Vogel conflict test in the rat, antibodies to S100 proteins increased punished drinking (anti-conflict effect) at 5 and 7.5 mL kg(-1), but not at 2.5 or 10 mL kg(-1). Antibodies to S100 proteins increased the percentage of entries into the open arms of an elevated plus-maze at 10 mL kg(-1), but not at lower doses. Taken together, these results indicate the presence of anxiolytic-like activity for antibodies to S100 proteins over the dose range 5-10 mL kg(-1) in the adult rat.

Farmacological effects of anti-S 100 in release-active form and mechanisms of their realization

Antibodies to 5100 proteins (anti-5100) in release-active form (RA anti-5100) are an active component of some domestic drugs(tenoten, tenoten for children, divaza, brizantin, kolofort and proproten-100). The authors present the results of preclinical and clinical trials (with detailed consideration of experimental data) which demonstrated a wide spectrum of specific pharmacological activity and safety as well as mechanisms of anti-5100 action.
