Definitions
- the present invention relates to a new therapeutic use of superoxide dismutases (SOD).
- SOD superoxide dismutases
- SOD was characterized in 1968 by Me CORD and FRIDOVICH; it is an enzyme which promotes the elimination of the superoxide radical (-O 2 -), a priori constitutes a protective mechanism against the deleterious effects of this radical, capable of forming in vivo from oxygen atmospheric, and therefore plays a crucial role in the prevention of toxic effects which could result from exposure to an oxygenated atmosphere.
- SODs tested those which have a prolonged half-life and a low incidence of immunological accidents are preferred; mention may be made in particular of Cu, Zn-SOD of bovine origin (homodimere which catalyzes the dismutation of the superoxide radical), Mn-SOD, Fe-SOD, liposomal SODs, SODs conjugated with polyethylene glycol, polymers or copolymers of recombinant human SOD, Cu, Zn-SOD and Mn-SOD.
- the Applicants have found a new use of SOD preparations with prolonged duration of action, for obtaining a medicament intended to treat or prevent disturbances in brain performance, preferably cognitive brain performance, caused by a specific cerebral aggression or by a non-specific aggression.
- non-specific aggression for example electrical stimulation (plantar shock)
- specific cerebral aggression for example prolonged overall cranial irradiation
- said SOD preparation with a prolonged duration of action protects mammals from disturbances of brain performance both preventively and curatively.
- the preparation of SOD with a prolonged duration of action is in particular selected from liposomal SODs, SOD-polyethylene glycol conjugates and polymers or copolymers of SOD.
- the superoxide dismutase (SOD) is in particular Cu / Zn-SOD, Mn-SOD, Fe-SOD from mammals (murine, bovine, human) or a recombinant SOD.
- preparations can be administered either parenterally, preferably subcutaneously, or orally.
- the preparations based on SOD as defined above can be used, in mammals, and in particular humans, for the curative or preventive treatment of disturbances in cognitive brain performance caused by a specific cerebral aggression (irradiation for example) or by non-specific aggression (electrical stimulation, for example).
- SOD doses are effective on complications of radiotherapy with a wide range of dosages, ranging from 2.3 mg / kg in pigs to 0.03 mg / kg in humans. In humans, a daily dose of between 0.03 mg / kg and 0.08 mg / kg will preferably be prescribed for the subcutaneous route.
- the invention also comprises other provisions, which will emerge from the description which follows, which refers to examples of implementation of the method which is the subject of the present invention.
- EXAMPLE 1 Preventive effect of SOD treatment on non-specific aggression (electrical stimulation).
- 0.5 mg / kg of liposomal Cu / Zn SOD at a rate of 0.05 ml / 100 g of rat weight is administered subcutaneously to the liposomal Cu / Zn SOD group.
- the control group received an equivalent volume of 0.9% NaCl.
- Two-way avoidance The animals must move from one compartment A to another B, in order to avoid the electric shock (1.5 mA for 15 seconds) applied alternately, either to the floor of cage A, or to the floor of cage B.
- a conditional sound stimulus 300 Hz allows them to avoid this shock, provided that they react within a period of time of 6 seconds (duration of the conditional stimulus and the interval).
- the learning takes place in three consecutive days at the rate of one session per day. Each session is made up of 15 trials. The interval between tests is 50 seconds. The number of avoidances, escape failures, and the time of exposure to plantar shock are recorded.
- Cu / Zn liposomal therefore attenuates the harmful effects of a non-specific aggression (electrical stimulation), which disrupts the acquisition of learning. Indeed, prior subcutaneous injections of SOD allow the preservation of the learning capacity.
- the rats were anesthetized with 250 mg / kg of chloral hydrate (ip route), at a rate of 0.5 ml / 100 g of their weight.
- the rat brain was treated by two opposite beams, also weighted of telecobalt. The two beams were treated the same day.
- a dose of 30 Gy was delivered in 10 fractions over 12 days on isodose 95% of the dose at the isocentre after computer dosimetry.
- the oral cavity, the muzzle, the eyes and the cervical spinal cord were protected by a personalized lead cover, 5 cm thick, placed close to the skin entry point. The distance between the source of cobalt 60 and the axis is 80 cm. After irradiation, the rats were housed in their original cages (4 to 5 animals each). - Behavioral test:
- Two-way avoidance The animals must move from compartment A to another B in order to avoid the electric shock (0.8 mA for 15 seconds) applied alternately, either to the floor of cage A, or to the floor of cage B.
- a stimulus conditional sound 300 Hz allows them to avoid this shock, provided that they react within a period of time of 6 seconds (duration of the conditional stimulus and the interval).
- the learning takes place in five consecutive days at the rate of one session per day. Each session is made up of 15 trials. The interval between tests is 50 seconds. The test is introduced one month after irradiation. Four recall sessions are offered: 2 1/2, 4 1/2, 8, and 9 months after irradiation. The number of avoidances is recorded.
- treatment with SOD improves the performance of rats who have become chronically deficient, under the effect of irradiation.
- irradiation of 30 Gy in 10 sessions and 12 days significantly and chronically alters the cerebral cognitive performance of elderly rats, without causing cerebral morphological anomalies under light microscopy, while subcutaneous injections of SOD 9 months after irradiation significantly improves the performance of rats, bringing them closer to that of non-irradiated control rats.
