 US 4,613,593
discloses a method for treating hyperlipidemia or arteriosclerosis which comprises administering to a subject a composition comprising inter alia
dolichol , a group of long-chain organic compounds with varying numbers of isoprene units, especially dolichol phosphate, dolichol dipolyphosphate and dolichol tripolyphosphate.
 EP 0 699 440 A1
discloses a therapeutic composition for pancreatitis which comprises ascorbyl tocopheryl phosphate, which is a diester of tocopherol (vitamin E) and ascorbic acid (vitamin C).
The known drugs can only eliminate symptoms of the disease and are not used for prophylaxis.
Disclosure of the invention
The technical result of using the claimed drug for use in the prophylaxis and treatment of acute and chronic pancreatitis consists in the elimination of inflammation and stimulation of the regeneration of pancreas cells.
Said technical result is achieved due to the fact that the drug for prophylaxis and treatment of acute and chronic pancreatitis contains a mixture of different polyprenyl phosphates and polyprenyl pyrophosphates with 7 to 30 isoprene unitsin the mass ratio from 5:1 to 20:1, preferably 9:1.
The new drug is administered intramuscularly, intravenously, intraperitoneally, orally, or by direct treatment of the pancreas during an operation. The drug can be administered in dry and liquid forms (tablets, capsules, suppositories, solutions for injections).
The drug is usually introduced 5 times in a dose corresponding to 10 (5-20) mg of active substance per 1 kg of body mass once a day (or once in two days).
The drug was tested and proved efficient.
The experiments were carried out on white rats weighing 180-220 g. The tissue of the pancreas was damaged by acetic acid (0.025 ml), which was applied on the pancreas surface.
The acute phase: introduction (intraperitoneal) from the first day of the reproduction of pancreatitis during 5 days.
The chronic phase: introduction (intraperitoneal) - on the first, third, fifth, seventh, ninth day.
The experiment was performed on two groups (acute and chronic pancreatitis) each-consisting of 5 animals.
Control 1: the reproduction of pancreatitis and introduction of a physiological solution without introducing the drug; two groups (acute and chronic pancreatitis) each consisting of 5 animals.
Control 2: administering the drug to 5 intact animals, i.e. without damage of the pancreas.
After killing the animals, organs of the abdominal cavity were revised, and dynamic morphological investigations were carried out.
The proposed model of experimental pancreatitis, the chemical effect of acetic acid on the pancreas tissue enables a study of the influence of the drug on the "acute" and "chronic" stage of the development of pancreatitis. The autopsy of the animals on the 5th
day after the reproduction of experimental pancreatitis and revision of organs of the abdominal cavity showed that only in one rat (10%) among the animals injected with the drug the inflammatory phenomena were more pronounced as compared to other animals of the group (9 animals, 90%). The damage to the pancreas is reduced by 90%.
Acute pancreatitis. Autopsy of the animals on the 5th
day after the reproduction of pancreatitis.
Control: acute pancreatitis, without treatment pancreas is edematic, it is closely bound to the surrounding tissues, numerous necroses of the pancreas tissue are visible, hyperemia of surrounding tissues. It is impossible to separate the pancreas.
Experiment: treatment with the drug - pancreas is edematic. Small single zones of necrosis. The pancreas tissue is closely bound to the surrounding tissues, but easily separated without injuries and bleedings.
Chronic pancreatitis. Autopsy of the animals on the 12th
day after the reproduction of pancreatitis. Revision of the abdominal cavity: in the group of animals without administering the preparation interintestinal abscesses remain. Necrosis of soft tissues of the stitch. Hyperemia of organs of the abdominal cavity. The pancreas is bound to the surroundings organs and tissues.
The group of animals after the administration of the drug: There are no foci of necrosis, intestine loops lie freely. The pancreas is easily separated. Hyperemia of organs of the abdominal cavity, hemorrhage is absent when touching.
Control 12 days after the pancreatitis reproduction, without treatment. Single necroses in the pancreas tissues. Hyperemia of the surrounding tissues. The separation of the pancreas is difficult; local hemorrhage may be increased.
Experiment: chronic pancreatitis, twelve days after the pancreatitis reproduction, drug introduction, no abscesses are observed in the revision of the abdominal cavity, the pancreas and surrounding tissues are not bound. The pancreas is easily separated. The tissue is edematic, tuberous. There are no necrosis foci, hyperemia of the pancreas and surrounding organs is preserved.
