Description
Technical Field
The invention belongs to the technical field of biological medicines, and particularly relates to application of low-molecular-weight fucoidan in preparation of a drug for resisting hyperactivity.
Background
Attention Deficit Hyperactivity Disorder (ADHD) is a highly heterogeneous group of neurodevelopmental diseases, with clinical symptoms manifested as Attention Deficit disorders and or Hyperactivity disorders. ADHD is complex in etiology and has individual variability, and the biological mechanism of ADHD pathogenesis is not clarified yet. ADHD is currently considered to be a syndrome of multiple disorders caused by multiple causes, and is associated with a variety of factors including genetics, psychology, and neurobiology. The genetic factors are the main causes of ADHD, the genetic degree of the ADHD reaches 80 percent, and the ADHD has obvious familial aggregation. Neurobiology and neuroimaging research finds that ADHD children have frontal lobe function and cortical junction defects, and cortical development delay causes executive dysfunction, so that problems in response inhibition, attention control and working memory occur. The central symptoms of ADHD are caused by the deregulation of dopamine, norepinephrine, 5-hydroxytryptamine. Therefore, the current clinical treatment of ADHD mainly takes western medicines with the effects of regulating neurotransmitter level and improving inhibition on prefrontal lobe activity as main medicines, including central stimulant methylphenidate, amphetamine and pimoline, and central norepinephrine regulation medicines of tomoxetine and clonidine. NICE evidence-based recommendations suggest methylphenidate and tomoxetine as first-line treatments for ADHD. The Chinese guideline for preventing and treating attention deficit hyperactivity disorder recommends tomoxetine with higher safety as a first-line treatment medicament. Tomoxetine selectively inhibits presynaptic operation of norepinephrine and increases norepinephrine function, thereby improving ADHD symptoms, but adverse reactions of tomoxetine include severe liver injury, causing dizziness, headache, insomnia, lethargy, and gastrointestinal reactions such as nausea, anorexia, dyspepsia, abdominal pain, and the like. Therefore, a novel anti-hyperactivity disorder medicament which is safe, efficient and free of toxic and side effects is clinically needed.
Based on the defects that western medicines are accompanied with various adverse reactions and are narrow in applicable population and the like, researchers transfer the eyesight to safer natural components such as astragalosides and ginsenosides, and study the treatment effect of ADHD by using important compound preparations and single natural product components. Fucoidan is a sulfated polysaccharide containing fucose as main component monosaccharide, and has multiple biological activities of regulating immunity, resisting oxidation, resisting tumor, resisting blood coagulation, resisting bacteria, resisting virus, resisting complement activation, resisting radiation, and treating cardiovascular diseases and kidney diseases. A great deal of research shows that the molecular weight of the polysaccharide has significant influence on the pharmacological activity, the digestion and the absorption and the safety of the polysaccharide. For example, in animal models of collagen-induced arthritis, high molecular weight fucoidan acts in contrast to low molecular weight fucoidan, which enhances The inflammatory process by enhancing The immune activation of macrophages, while low molecular weight fucoidan inhibits The development of arthritis by inhibiting Th-1 mediated immune responses (The differential effect of high and low molecular weight polysaccharides on The basis of The sensitivity of collagen-induced arthritis microorganism Research,2010,24,1384-1391). So far, reports of brown algae polysaccharide sulfate and sea urchin polysaccharide in the aspect of resisting hyperactivity are not seen. The invention discloses that low molecular weight fucoidin has obvious anti-hyperactivity activity for the first time by using the accepted young SHR rat as a hyperactivity model animal to carry out in-vivo animal experiments, and lays a foundation for developing the application of marine polysaccharide anti-hyperactivity drugs and health care products.

Pharmacodynamics of low molecular weight fucoidan for improving hyperactivity
The fucoidan sulfate of low molecular weight of example 1 and the echinus polysaccharide of example 2 were accurately weighed, dissolved in normal saline, and the solvent was prepared in an amount of 100mg/Kg for intragastric administration. The gavage is carried out according to the weight of the rat per 100g and the liquid medicine amount of 1ml, the gavage is carried out for 1 time every day, and the gavage is continuously carried out for 21 days. 10 WKY rats as normal control group were subjected to intragastric administration of physiological saline; 40 SHR rats were divided into 4 groups according to body weight, and divided into BLK group (gavage physiological saline), ATO group (gavage 5mg/Kg tomoxetine), DFPS group (gavage 100mg/Kg low molecular weight fucoidan-obtained in example 1), and HT group (gavage 100mg/Kg echinacon-obtained in example 2).
(1) Body weight and food intake
Animals were monitored for weight change every 3 days. The level of food intake of the animals was measured at the initial stage of administration and one week after administration. According to the number of animals per cage, 50 g/feed is given, the balance is weighed every 3 days and made up to the initial level, and the average food intake per day of the animals is calculated according to the difference.
The results are shown in fig. 1-2, and fig. 1 shows that the body weights of animals in various groups of SHR at the initial administration stage are not obviously different, the body weights of animals in ATO group are obviously fluctuated in the middle and later stages, which indicates that tomoxetine may influence the growth and development of animals and the desire to eat, and the body weights of animals in DFPS group and HT group are uniformly increased, which indicates that DFPS and HT have no toxic or side effect on animal bodies. The body weight levels of the animals in each group were substantially maintained as DFPS > HT > BLK > ATO > WKY. FIG. 2 shows that there is no significant difference in average intake amount between SHR groups and WKY groups at the initial administration stage, and after one week of administration, the intake amount of BLK animals is significantly higher than those of ATO group and DFPS group, and significantly higher than that of WKY group (p < 0.05), which indicates that the drug may reduce the intake amount by reducing the activity level of animals.
(2) Effect of drugs on animal motion levels in open field
The open field experiment divide into 3 stages, and the animal is tempered in the earlier stage of dosing, divides into groups the animal through the first open field experiment, and the later stage of dosing carries out the second open field experiment, and the motion level of inspection animal, anxiety, exploration level.
1. An exercise period:
after the adaptive feeding period, the animals were subjected to open field exercise. 3h before the start of the experiment, the animals were transferred to a behavioural laboratory to exclude increased activity of the animals due to stress or a novel environment. The open field experimental box is a wooden box with the height of 40cm and the bottom of 50cm multiplied by 50 cm. Animals were placed in the central area of the experimental box and allowed to move freely for 3min.
2. The first field-opening experiment:
after the animals are subjected to the open field exercise, the first open field experiment is carried out. The animals are placed in the central area of the test box and allowed to freely move for 5min, and weak light illumination is adopted in the experimental process to keep the environment stable and the light and noise consistent. After the experiment started, the experimenter separated from the animals immediately, and after the experiment was finished, the tested animals were taken out, and the test area was cleaned with 75% alcohol to avoid the smell from interfering with the next animal. The movement of the animals in the open field was recorded and analyzed using smartv3.0.0.6.
3. Second field opening experiment:
14 days after dosing, a second open field experiment was performed. The experimental operation is the same as the first field-opening experiment. And evaluating the influence of the medicament on the movement level of the animal according to the indexes of the total movement distance of the animal, the movement distance (%) in the central grid, the total number of grids passing through, the number of times of entering the central grid, the rest time, the erection time and the like.
The results are shown in FIGS. 3 to 4. The distance of movement of the animal in the open field, the number of grid crossings, the number of entries into the central zone, the number of erections, indicate the level of hyperactivity, anxiety and curiosity sought by the animal. FIG. 3A shows that the total kinesthetic distance in the open field was significantly lower for the WKY group animals than for the BLK group (p < 0.05), with the ATO and DFPS groups being significantly lower than for the BLK group; FIG. 3B shows that the number of crossing lattices of animals in the WKY, ATO and DFPS groups is significantly lower than that in the BLK group (p < 0.05); FIG. 3C shows that the number of entries into the central region was significantly lower in the WKY and DFPS groups than in the BLK group (p < 0.05); FIG. 3D shows that the animals in the WKY, ATO, and DFPS groups were significantly less erect than the BLK group (p < 0.05). Fig. 4 is a trace of the animal's locomotion during the open field, illustrating that DFPS effectively inhibits the level of hyperactivity and anxiety in the animal. HT animals have no obvious improvement effect in all aspects of the open field experiment.
(3) Morris Water maze test for animal behaviourology
The Morris water maze experiment is divided into 2 stages, including a 5-day oriented navigation experiment and a 1-sky exploration experiment, so as to explore the space learning and working memory capacity of animals.

The water maze consists of a prototype reservoir with the diameter of 180cm and the height of 50cm and a black iron platform, wherein the water depth in the reservoir is 25cm, the water temperature is controlled to be 25 +/-1 ℃, ink is added into the water, and the platform cannot be seen when the reservoir is opaque. The pool is divided into four quadrants of 1, 2, 3 and 4 artificially and evenly, a platform is placed in the 3 rd quadrant, and the area of the top plane of the platform is 8cm multiplied by 8cm. And the peripheral pure-color curtain is used for sticking patterns with different colors and shapes above four quadrants of the curtain to be used as the directional marker of the animal. In a directional navigation experiment, a platform is arranged to be exposed out of the water surface on the 1 st day, animals are placed in the center of the first quadrant in a manner of facing the pool wall, the exploration time is given for 60s, if the animals do not find the platform, the animals are guided to ascend the platform, each animal is guaranteed to stay on the platform for 20s for observation and memory, and the animals are fished out, wiped dry and placed back into a cage.
2. Experiment of directional navigation
And on days 2-5, arranging the platform 2cm below the water surface, putting the animals facing the pool wall from the centers of quadrants 1, 2, 3 and 4 respectively, evacuating the experimenters immediately to avoid forming wrong reference for the animals, ensuring no shadow on the water surface and avoiding software recognition errors, guiding the mice to travel to the platform and enabling the mice to stay for 20s if the mice 60s cannot reach the platform by self, and allowing all the mice to stay for 20s after reaching the platform to form space memory. Latency for animals to find the platform was recorded and analyzed using smartv3.0.0.6.
3. Experiment of space exploration
And (4) withdrawing from the platform on the 6 th day, carrying out a space exploration experiment, putting the animal into the platform from the first quadrant, analyzing the latency of the animal entering the area where the original platform is located, the number of times of shuttling the platform area, and the distance and time in the platform area by utilizing Smartv3.0.0.6.
The results are shown in fig. 5-7, fig. 5 shows that in the directional sailing experiment, the latency of the animals for finding the platform is shortened along with the increase of sailing times, the latency of the animals for finding the platform is shorter in the DFPS group and the HT group than in the model group, and DFPS < HT < ATO < BLK < WKY; fig. 6A shows that the percentage of the moving distance of the animal in the original platform area is higher than that of the DFPS group, fig. 6B shows that the number of times of the animal entering the original platform area is higher than that of the BLK group, and fig. 7 shows that the moving trajectory of the animal in the water maze is biased, the moving trajectory of the animal in the BLK group is disordered, and the animals in the DFPS group and the HT group are biased to search in the platform area, which shows that the DFPS effectively improves the spatial memory ability of the animal, and the HT has no obvious effect on the spatial memory ability of the animal.
