ABSTRACT
OBJECTIVE:To observe the clinical efficacy and safety of Bromfenac sodium eyed drops in the treatment of xe-rophthalmia. METHODS:80 patients with xerophthalmia were randomly divided into observation group and control group,with 40 cases in each group. Control group was given 0.1% Sodium hyaluronate,one drop,qd;observation group was given 0.1% Sodi-um hyaluronate eye drops,one drop,bid. Both groups received 14 d of treatment. The subjective symptom and sign,the time of lacrimal film break-up,fluorescent staining score and schemer test were observed in 2 groups before treatment,3,7,14 d after treatment. Clinical efficacy and the occurrence of ADR were observed in 2 groups. RESULTS:There was no statistical significance in subjective symptom and sign,the time of lacrimal film break-up,fluorescent staining score and tear between 2 groups before treatment,3,7 d after treatment(P>0.05). 14 d after treatment,subjective symptom and sign and fluorescent staining score of 2 groups were decreased significantly,and the time of lacrimal film break-up was prolonged and secretion was increased significant-ly;the observation group was significantly better than the control group,with statistical significance (P0.05). CONCLUSIONS:Sodium hyaluronate eye drops is effective for xerophthalmia,and can relieve the symptoms with good safety.
ABSTRACT
Objective:To study the osseointegration of implant in fresh extraction socket with or without bone grafting.Methods:In the mandibular premolar region of 6 beagle dogs,bone defect in the size of (3~4)mm ×(3~4)mm ×(5 ~6)mm on the mesial wall of the mesial root socket was made.On control side implants were installed immediately into the extraction sockets(group A).On an-other side Bio-Oss grafts and membrane(GBR)were placed following implantation(group B).All animals were sacrificed 3 months af-ter implantation,specimens were examined for histo-morphometric analysis of bone to implant contact and new bone formation.Results:No implant was loosening in the 2 groups.New bone was filled in the bone defect areas in 2 groups.No statistical difference of the per-centage of new bone formation and bone-to-implant contact ration(BIC)was observed between 2 groups.Conclusion:With the defect in a certain size on the root socket wall osseointegration may occur between the new bone and implant without bone transplantation.
ABSTRACT
OBJECTIVE:To study clinical efficacy and adverse drug reaction(ADR) of Cyclopentolate hydrochloride eye drops,Tropicamide eye drops and Atropine eye drops.METHODS:600 asthenopic children were divided into 3 groups according to visiting time sequence(n=200).3 groups were treated with 1% Cyclopentolate hydrochloride eye drops,1% Tropicamide eye drops and 1% Atropine eye drops respectively.Mydriasis effects of 3 groups were observed and results of retinoscopy were recorded.Ocular ADR and systemic ADR were surveyed.RESULTS:The level of ocular ADR and systemic ADR of tropicamide group were lower than other 2 groups(P
