By table 7 result as seen: preparation of the present invention can make the food ration of rat increase when low dosage, and its effect strengthens with increase of dosage, compares significantly with matched group during high dose and increases (P<0.05).It is strong slightly the effect that clinical consumption Endothelium Corneum Gigeriae Galli looses such as to compare.
The influence that 6 pairs of rat body weights of experimental example increase
Get the Wistar rat of test, male and female half and half with the 90-105g body weight.Grouping, administration are with above-mentioned embodiment.Feed with capacity essence, greenfeed, freely drink water.Weigh morning next day after the last administration, with body weight difference before the administration be the index of body weight gain.Be calculated as follows the body weight gain rate.
Result such as table 8.
The influence that table 8 preparation of the present invention increases rat body weight
Group | Dosage (g/kg.d) | Number of animals (only) | The intestinal propulsion rate (%, X ± SD) |
Contrast | Deng capacity * 7d | 10 | 21.15±3.21 |
The present invention | Low dosage | 0.81×7d | 10 | 22.19±2.82 |
High dose | 2.43×7d | 10 | 23.50±2.67 |
Endothelium Corneum Gigeriae Galli looses | 2.43×7d | 10 | 23.27±2.74 |
Table 8 is the result show: preparation of the present invention and Endothelium Corneum Gigeriae Galli loose the rat body weight rate of increase is increased, but with matched group difference with insignificance (P>0.05), may be because administration time be short (so long term toxicity test is because dosage is big, administration time is long, and the body weight gain rate is significantly increased).
Above animal experiment shows that preparation of the present invention can promote the gastric emptying of mice, the intestinal propulsion function, and can suppress the hyperfunction gastrointestinal motility of " insufficiency of the spleen " mice, illustrating has dual regulation to the gastrointestinal motility function.Still can significantly increase the gastric secretion of rat, total acid and pepsin output, improve peptic activity of stomach.Illustrate that preparation of the present invention has the effect that strengthens mechanicalness and chemical digestion, this has also obtained further confirmation in the test of preparation energy appetite stimulator of the present invention, increase rat food ration.Irritating body weight gain that stomach gives the precious rat of my child in continuous 7 days has the effect trend of increase, illustrates that also preparation of the present invention has the effect that strengthens digestive function.
Clinical trial
The present inventor utilizes the preparation for treating infantile anorexia of preparation embodiment 1, has carried out clinical observation, and the result is summarized as follows.
Object and method
One, physical data
30 routine patients are all from Hospital Attached to Liaoning Inst. of Traditional Chinese Medicine Pediatric Clinic patient, male's 18 examples, women's 12 examples, the oldest 12 years old, minimum 2 years old, average 5.5 years old.Simple weakness of the spleen and stomach person 24 examples, weakness of the spleen and stomach dyspepsia inner stopper 6 examples of holding concurrently.The course of disease is the shortest two months, and is the longest 48 months, average course of disease 26 months.
Two, diagnostic criteria
Tcm diagnosis, medicine typing standard with reference to due to weakness of spleen and stomach in " Pediatrics of Chinese Medicine " five editions relevant infantile anorexia of teaching material.
1. infantile anorexia diagnostic criteria
(1) long-term inappetence, and do not have other disease patient, the course of disease is more than 2 months.
(2) lustreless complexion, body are thin partially, but spirit is fair, no abdominal distention.
(3) the improper feeding history is arranged, do not have at regular time and quantity, feed raw food, sweet savoury or monophagia etc. as feed.
2. qi-deficiency of spleen and stomach infantile anorexia diagnostic criteria
Cardinal symptom: 1. anorexia or refusing to eat; 2. shallow complexion
Minor symptom: 1. refreshing tired weak; 2. emaciated physique; 3. big loose stool is thin; 4. pale tongue with white fur; 5. moderate pulse is unable.
Diagnosis: possess any two of cardinal symptom and minor symptom, can establish diagnosis.
Therapy: give the pharmaceutical preparation that obtains by preparation embodiment 1, every day 3 times, 2-3 year infant obey 0.5g at every turn, the 4-8 infant is obeyed 1.0g at every turn, each clothes 2.0g of 9-12 year.
Three, curative effect determinate standard: formulate with reference to the relevant apositia content of " disease of tcm criterion of therapeutical effect " department of pediatrics part.
1. clinical recovery: appetite and appetite all recover normal; Weight recovery is to standard body weight; Other clinical symptoms disappears substantially.
2. produce effects: appetite and appetite all obviously increase; Body weight obviously increases, and body weight is near the mark; Other clinical symptoms is obviously improved.
