Claims

1. A method for stimulating cells in the human immune system of a patient, comprising administering to the patient a substance prepared according to a method comprising: leaching homogenate of Laminaria Japonica and Laminaria Angustata algae with a mixture of an aqueous solution and an isobutanolic solution, with a 1 g:2.5 ml:2.5 ml mix ratio, to obtain a homogeneous mixture; heating the homogenous mixture at 60° C. for one hour; incubating the homogenous mixture for 10-15 hours at room temperature to obtain a supernatant; withdrawing the supernatant from the homogenous mixture and centrifuging the supernatant at 3000 rpm and +4° C. for 30 minutes to obtain a centrifuged supernatant; purging the centrifuged supernatant with argon to obtain a purged, centrifuged supernatant and vacuum drying the purged, centrifuged supernatant for one hour at room temperature, followed by vacuum drying at 60° C. until a liquid fraction of the supernatant evaporates, to obtain a sediment; diluting the sediment with water to produce a 5% solution and then ultracentrifuging the 5% solution at 100,000 rpm for one hour to obtain a second supernatant; withdrawing the second supernatant and centrifuging the second supernatant in 10 kD filter tubes for one hour at 5000 rpm to obtain a lower percolated fraction; withdrawing the lower percolated fraction and centrifuging the lower percolated fraction in 5 kD filter tubes for one hour at 5000 rpm to obtain an upper fraction detained by a filter in the filter tubes; and withdrawing the upper fraction from the filter and diluting the upper fraction in 500 ml of NaCl saline to obtain a substance with a final concentration of 10 mg/ml.

2. The method according to claim 1, wherein the method for preparing the substance administered to the patient further comprises, after centrifuging the supernatant and prior to purging the centrifuged supernatant, ultracentrifuging the centrifuged supernatant at 100,000 rpm for one hour.

Description

DETAILED DESCRIPTION

[0010] Enterocytes and goblet cells, found in extrathoracic trachea and pancreatic and parotid ducts as well as segments of the digestive system, are three times more permeable to 5-10 kD molecules than other digestive system cells, including stem and Paneth cells. Consequently, the cell pools partly responsible for tissue immunity manifestations and the digestive system's protective functions and also for the ingress of substances from the digestive system into the bloodstream turn out to be the cell pools most permeable to the algal extract as compared to others. As a result, the active algal extract can enter the bloodstream both paracellularly and transcellularly (through the enterocytes). The greater permeability of certain digestive system cells and the algal extract's small particle size (5-10 kD) and lack of a complicated 3D structure combine to make it highly bioavailable. Studies of the medication's efficiency showed 1 ml once-daily ante cibum oral administration to be the safest and most efficient regimen.

[0011] The above method for obtaining individual fractions of Laminaria Japonica and/or Laminaria Angustata consisting of 5 to 10 kD molecules seems optimal and permits more than 10,000-fold enrichment of the fraction from its initial content.

[0012] The proposed method's algorithm is as follows:

[0013] To obtain the said fractions from dried and powdered homogenate of algae (Laminaria Japonica and Laminaria Angustata) by leaching with butanol and water mixture, we leach powdered Laminaria in water and isobutanol solution (1 g:2.5 ml:2.5 ml). To this end, we pour 500 ml of isobutanol into a 121 bottle, then add 200 g of powdered Laminaria and stir until the solution is homogeneous and dark green in colour. Ten minutes later, we add 500 ml of distilled water into the bottle and stir again until homogeneous. The resultant mixture is heated in water bath or a thermostat at 60° C. and then incubated for 10-15 hours at room temperature; then supernatant is withdrawn and centrifuged in an Eppendorf Centrifuge 5804 R at 3000 rpm and +4° C. for 30 minutes. The supernatant thus obtained should be withdrawn, placed into a vacuum evaporator and blown through with argon. The resultant supernatant is then vacuum-dried as follows: at room temperature for one hour, to avoid ebullition as suction is applied, and then at 60° C. until complete evaporation. Then we prepare 5% aqueous solution and ultracentrifuge it at 100,000 rpm for one hour. The resulting supernatant should be withdrawn and centrifuged again, now in 10 kD filter tubes, for one hour at 5000 rpm on the Eppendorf Centrifuge 5804 R apparatus. The lower percolated fraction is then withdrawn and centrifuged in 5 kD filter tubes, for one hour at 5000 rpm on the Eppendorf Centrifuge 5804 R7 apparatus. Then the upper fraction detained by the filter is withdrawn and 500 ml of NaCl saline is added. The medication obtained is used as follows: 1 ml of the medication is diluted in 20 ml of water and ingested once a day before a meal for two weeks. The medication consists of 5 to 10 kD molecules.

Example 1

[0014] A female patient, aged 40, was referred to an immunologist by her GP as she had had frequent ARD episodes (4-5 per year) in the past three years and complained of fatigue, drowsiness and persistent weakness. Her history was unburdened, with two pregnancies, both delivered (at the age of 23 and 27); physical examination found no abnormalities. The blood cell count and chemistry tests and clinical urine test found none, either. The immunologist ordered an examination of her immune status, which found a reduced pool of natural killers and B lymphocites while their absolute values remained normal. The patient was started on our medication, with 1 ml administered orally in 20 ml of water before meals, once daily for two weeks. One month after the start of treatment, the patient noted a subjective improvement in her status, with lesser weakness and fatigue; she found it easier to get up in the morning (while her daily regimen remained the same). Objectively, re-examination of her immune status showed an increase in her natural killer and B lymphocyte pools that doubled and trebled, respectively.

Example 2

[0015] A male patient aged 60, with no abnormal history, consulted the immunologist on his own and reported occasional joint pains, acrimony and sleeping problems (difficulty falling asleep and awakening). Examination at the internal medicine department of a private clinic found no abnormalities. Immune status examination showed decreased count of natural killers (relatively) and humoral immunity factors (IgA and IgM). The patient was started on our medication, with 1 ml administered orally in 20 ml of water before meals, once daily for two weeks. One month after start of treatment, the patient reported better sleep (quick going to sleep with no waking in the night) and improved mood. Noted objectively one month after the start of treatment were an increase in humoral immunity factors and normalized lymphocyte population ratios.

[0016] The above examples show that the medication whose active substance is 5-10 kD molecules from Laminaria Japonica and Laminaria Angustata leads to normalization of the patients' immune status and a subjective feeling of improved health.
