Experimental example 6: to the effect of Cavia porcellus allergic rhinitis
Laboratory animal: healthy guinea pig, male and female are regardless of, body weight 350 ~ 400g, are provided, the quality certification number by meter Xie Er biological product company limited of Shandong Province: Shandong kinoplaszm word D20120608.
Medicine: medicine prepares gained by embodiment 3 method, lot number is 20150912; Cangyi nose drops agent (Foshan Dezhong Pharmaceutical Co., Ltd.); Toluene-2,4-diisocyanate, 4-vulcabond (sigma, lot number: SHBD198V); Olive oil (chemical reagents corporation of traditional Chinese medicines group).
Grouping and administration: get 40 healthy guinea pigs, be divided at random blank group, model group, medicine group and positive controls (Cangyi nose drops agent) 4 groups, often organize 8.Cavia porcellus bilateral nostril is all instilled 6% Toluene-2,4-diisocyanate, 4-vulcabond olive oil solution (TDI) 5 μ L, every day 1 time, continuous 7d, sets up allergic rhinitis guinea pig model.Administration period TDI be two days 1 inferior to 1h collunarium after administration.Blank group Cavia porcellus bilateral nostril instillation equivalent olive oil.Blank group, each bilateral nostril of model group respectively instill normal saline 5 μ L, and each bilateral nostril of positive controls respectively instills Cangyi nose drops agent 5 μ L, and each bilateral nostril of medicine group respectively instills spray 5 μ L, every day 2 times, continuous 14d.Grab the number of times of nose, sneeze after stimulating with TDI before recording each group of Cavia porcellus administration in 15min, the results are shown in Table 6.
Table 6 medicine on allergic rhinitis guinea pig model grab nose and sneeze number of times impact (
± s)
Note: compare with blank group, a:p<0.01; Compare with model group, b:p<0.01
Show the effect experiment result causing Cavia porcellus allergic rhinitis, administration group grabs nose number of times and sneeze significantly lower than model group, and the spray for treating rhinitis of preparation obviously can alleviate Cavia porcellus rhinocnesmus, sneeze symptom.
Experimental example 5: toxicology test
Laboratory animal: Wistar rat, male and female half and half, body weight 200 ~ 250g, is provided by Taishan Hospital's Experimental Animal Center.
Medicine: medicine prepares gained by embodiment 3 method, lot number is 20150912;
1, acute toxicity test
Grouping and administration: get 30 rats, be divided into blank group, adjuvant matched group and spray group at random, often organize 10, male and female half and half.Bilateral spray nasal administration, every side 1 is pressed, and observes the diet of rat, behavior, body weight, excretion, abnormal response and death condition after administration in 14 days.After observation terminates, will remain rat and dissect, whether observation nasal cavity, larynx, trachea-bronchial epithelial cell mucosa there is pathological changes.
Result shows, after administration, in 14 days, rat diet, behavior, body weight and excretion situation and matched group are without obvious difference, and nothing is dead.Observe nasal cavity after dissection, the change such as redness, hyperemia do not appear in larynx, trachea-bronchial epithelial cell mucosa, fester.
2, long term toxicity test
Grouping and administration: get 50 rats, be divided into blank group, adjuvant matched group and spray high dose group (clinical 4 times of concentration), middle dosage group (clinical 2 times of concentration) and low dose group at random, often organize 10, male and female half and half.Bilateral spray nasal administration, every side 1 is pressed, every day 4 times, continuous 3 months.The diet of rat, behavior, body weight, excretion, abnormal response and death condition is observed during administration.After observation terminates, will remain rat and dissect, and carry out histological examination, whether observation nasal cavity, larynx, trachea-bronchial epithelial cell mucosa there is pathological changes.Result shows, rat diet, behavior, body weight and excretion situation are normal, without dead.Observe nasal cavity after dissection, the change such as redness, hyperemia do not appear in larynx, trachea-bronchial epithelial cell mucosa, fester.
3, Local irritation study
Grouping and administration: get 30 rats, be divided into blank group, adjuvant matched group and spray group at random, often organize 10, male and female half and half.Bilateral spray nasal administration, each 1 presses, continuous use 1 week.After last administration, 24h puts to death, and gets nasal mucosa and does tissue slice inspection.Result shows, mucosa, without pathological change, shows that routine dose is to nasal mucosa nonirritant.
Experimental example 6: clinical practice
With 66 routine patients with rhinitis for object of study carries out clinical application research, patient suffers from chronic rhinitis.Patient is divided into 2 groups at random, and matched group uses Cangyi nose drops agent, and experimental group uses spray for treating rhinitis, bilateral spray nose, 4 times on the one, and each every side 2 ~ 4 is pressed, and uses 14d continuously.The sign that observes the symptoms change score, score standard is in table 7, and score the results are shown in Table 8.
Table 7 symptom score standard
Front and back scores treated by table 8
Note: compare with before organizing administration, a:p<0.01
Table 8 result shows, spray for treating rhinitis obviously can be eliminated or improve the Rhinitis Symptoms such as rhinocnesmus, nasal obstruction, sneeze, effect and matched group close.
