Comparative study on pharmacokinetics and toxicity of intravitreal and sub-Tenon injection of triamcinolone acetonide in ocular tissues

AIM:To compare the differences in kinetics,distribution,and toxicity of triamcinolone acetonide(TA)between the injection methods,sub-Tenon and intravitreal injections in rabbit ocular tissues.METHODS:TA was injected into the vitreous or the sub-Tenon in rabbits.For pharmacokinetic study,rabbits were sacrificed periodically and then TA in blood and ocular tissues(retina/choroids,vitreous,and aqueous humor)were measured over 91 d.For toxicological study,clinical signs,slit-lamp microscopic examination,ophthalmological test were performed.The eyeballs and surrounding tissues were collected and fixed with glutaraldehyde-formalin solution,and then paraffin embedded for histological investigation.RESULTS:Higher levels of TA were distributed in the intraocular tissues when injected into the vitreous compared to the sub-Tenon.Conversely,TA level was remarkably lower in the rabbits which received intravitreal TA injections than those treated with sub-Tenon injection throughout the study period in plasma.Optical discharge probably caused by systemic circulation of TA was observed by receiving sub-Tenon TA injection.Meanwhile,technicassociated toxicological ocular symptoms and findings were more frequently observed in intravitreal injection than in sub-Tenon injection.CONCLUSION:There are significant differences in kinetics and distribution of TA in vitreous body,aqueous humor and plasma,between the two injection methods.Although further study is needed to explain the species difference between human and rabbit,it is assumed that the difference in the frequency of intraocular pressure elevation and cataract formation by TA between the two injection methods are directly related to the TA concentrations in aqueous humor and vitreous body in each injection methods.Systemic toxicity and technic-associated toxicity are also closely related to kinetics of TA in plasma and each injection method itself,respectively.

Influence of Danshen Injection on airway inflammation and CD4^+ CD25^+ regulatory T cells of asthmatic rats

Objective： To investigate the influence of Danshen Injection on airway inflammation and CD4^＋CD25^＋ regulatory T cells（CD4^＋CD25^＋ Tr） of asthmatic rats, and elucidate the possible mechanism of Danshen Injection in treatment of asthma. Methods： 30 Wister rats were randomly divided into control group, asthma group and Danshen Injection treated group. Bronchoalveolar lavage fluids （BALF） were collected, and cytology studies were conducted. Lung tissues were obtained and pathologic analyses were done with hematoxylin and eosin stain （HE）. Flow cytometry was used to detect the CD4^＋CD25^＋ Tr ratio in peripheral blood mononuclear cells （PBMCs）. Results： Total cell, the percentage of lymphocytes, neutrophils and eosinophils （Eos） in BALF of Danshen Injection-treated group were lower than that in asthma group （P〈0.05, P〈0.01）. Compared with asthma group, less infiltration of inflammatory cells in lung tissues was observed in Danshen Injection-treated group. CD4^＋CD25^＋ Tr of asthma group was lower than that of control and Danshen Injection treated group （P〈0.05）. Conclusion： Danshen Injection can suppress airway inflammation of asthmatic rats, probably by increasing the number of CD4^＋CD25^＋ Tr.

Objective： The present study aimed to investigate the efficacy of Shenfu injection plus vinorelbine on the promotion of the quality of life （QOL） in elderly non-small cell lung cancer （NSCLC） patients. Methods： A randomized single blind trial method was used. Forty-six patients with stage IIIB-IV of HSCLC were randomly divided into experimental group and control group. In the experimental group, the patients were treated with 50 mL Shenfu injection from day 1 to 14, plus vinorelbine （NVB） 25 mg/m^2 on day 1 and 8. In the control group, the patients were only treated with NVB 25 mg/m^2 on day 1 and 8. After two cycle＇s of treatment, QOL, efficacy and toxicity were observed. Results： The QOL was enhanced in both experimental group and control group. However, the difference of KPS after treatment in the experimental group was markedly higher than in the control group （14 ± 10 vs. 8 ± 10, t = 2.116, P = 0.04）, improvement rate of QOL was better than in the control group （76.2% vs. 45.0%, χ^2 = 4.188, P = 0.041）, treatment related toxicity in the experimental group was also markedly lower than in the control group （χ^2 = 3.866, P = 0.049）, but the difference of efficacy between the two groups was not significant （14.3% vs. 15.0%, χ^2 = 0.161, P = 0.688）. Conclusion： Shenfu injection plus vinorelbine can enhance QOL in elderly NSCLC patients.

Cardioprotective effect of Danshen injectable powder on pressure overloadinduced ventricular remodeling in rats and isoproterenol induced myocardial injury in mice

OBJECTIVE To determine the effects of Danshen injectable powder on myocardial remodeling in pressure overload rats and isoproterenol(ISO) injection mice.METHODS SD Rats were subject to abdominal aortic constriction(AAC) surgery to develop pressure overload.Therapeutic effect of Danshen injectable powder was assessed six weeks after AAC surgery.The lactic dehydrogenase(LDH) and creatine kinase(CK) levels in serum,biometric,echocardiographic parameters,interstitial fibrosis,the expression of DJ-1 and SOD2 were then measured.The myocardial impairment in mice was induced by ISO injection.LDH and CK in serum,biometric,interstitial fibrosis were measured to investigate the cardioprotective effect of Danshen injectable powder.Matrix-assisted laser desorption mass spectrometry imaging(MALDI-MSI) was used to detect the changes of 60-1000 Da molecules in mice heart tissue.RESULTS In AAC rats,we observed compensatory hypertrophy and perivascular fibrosis,however cardiac function had not progressed to deterioration.The levels of LDH and CK were decreased significantly in the Danshen injectable powder groups(P<0.05,P<0.05).Danshen injectable powder could alleviate the perivascular collagen deposits but not cardiac hypertrophy in AAC rats.Furthermore,Danshen injectable powder enhanced the expression levels of SOD2 and DJ-1 in cardio.myocytes(P<0.05,P<0.01).In ISO injection mice,the levels of HWI and LDH were decreased signifi.cantly in drug treatment group compared with model group(P<0.01,P<0.01).In the MALDI-MSI of mice heart section,Danshen injectable powder can improve the reduction of energy metabolism-related substances including adenosine,creatine and ADP induced by ISO impairment.CONCLUSION Danshen injectable powder can attenuate perivascular fibrosis and improve the expression of antioxidative stress-related proteins SOD2,DJ-1 in the rats with pressure overload-induced left ventricular remodeling.Danshen injectable powder has cardioprotective effect on ISO impairment in mice which is probably related to improvement of energy metabolism.

Toxicity of Danshen Injection in Beagle's Dogs by Repeated iv Injection

Objective To re-evaluate the potential toxicity of Danshen Injection(DI) in Beagle's dogs by repeated iv injection.Methods DI was iv given to the dogs at the doses of 0,1.6,5.4,and 16.0 g/(kg·d)(4 per sex per group) for 13weeks.During the test period,the clinical signs,mortality,body weights,food consumption,rectal temperature,ophthalmoscopy,electrocardiography,urinalysis,hematology,serum biochemistry,organ weights,gross findings,and histopathology were examined.Results Dogs iv given with DI at the doses of 0,1.6,5.4,and 16.0 g/(kg·d) for13 weeks had no drug-related changes in mortality,body weight,food consumption,temperature,electrocardiography,ophthalmoscopy,urinalysis parameters,and organ weights.The hematological parameter data showed a significant decrease in red blood cells and hemoglobin concentration in the high-dose group and a significant increase in activated partial thromboplastin time suggesting an effect on haemopoiesis.For biochemical parameters,a significant decrease in glucose and a significant increase in total bilirubin were observed in the high-dose group,and the latter was considered to be toxicologically insignificant as lack of histopathological correlate.However,the histopathological examinations of the injection site showed that DI could cause dose-dependent focal inflammation.Conclusion That the iv injection with DI into dogs at 16 g/(kg·d) for 13 weeks could cause the decreases in red blood cell parameters and glucose,as well as the lesions of the injection site.The no observed adverse effect level is5.4 g/(kg·d),which suggests that safe clinical dosing be possible.
