消痤洁肤乳膏皮肤用药安全性实验研究 总被引:1,自引:0,他引:1
目的:评价消痤洁肤乳膏(含螺内酯和盐酸克林霉素)皮肤用药的安全性。方法:采用兔完整皮肤和破损皮肤分组涂布消痤洁肤乳膏和乳膏基质(每只1.0g)进行皮肤刺激实验(n=10);对豚鼠分组涂布消痤洁肤乳膏(每只0.2g)、乳膏基质(每只0.2g)、2,4-二硝基氯苯(每只0.2mL)进行皮肤致敏实验(n=50),2个实验均以红斑和水肿情况为评价指标;对大鼠分组涂布0.65、0.52、0.416g·kg-1的消痤洁肤乳膏和乳膏基质进行完整皮肤和破损皮肤的皮肤急性毒性实验(n=70),并设立对照组,观察各组大鼠7d内体质量变化、中毒反应及死亡情况。结果:消痤洁肤乳膏对兔完整皮肤及破损皮肤刺激强度、豚鼠致敏强度评分均为0,急性毒性实验中大鼠体质量变化无差异,未见死亡及中毒反应发生。结论:消痤洁肤乳膏是一种安全性较好的外用药。 相似文献

Ketoprofen (KP) is a widely used non-steroidal anti-inflammatory drug (NSAID). However, an increasing number of case reports
suggest that in broad use, KP can cause allergic dermatitis. Most of these adverse effects have been attributed to the photoallergic
potential of KP and photosensitivity. With the exception of a few reports in experimental animals, there is little evidence
that KP actually causes dermal toxicity. In this study, in order to investigate the eventual underlying causes of KP dermal
toxicity, we conducted primary irritation, skin cumulative, skin sensitization, phototoxicity and photosensitization tests
in rodents and rabbits. Primary irritation and skin cumulative testing using New Zealand white rabbits revealed that application
of KP (22, 15 and 10%) did not induce erythema or edema formation. Moreover, in skin sensitization and skin phototoxicity
testing, using Hartley albino guinea pigs, there was no evidence of allergic or phototoxic potential. In the photosensitization
test, KP induced skin reactions in six of eight guinea pigs with signs of erythema on the application site. Histologically,
in photosensitized skin, epidermal hyperplasia, including incremental stratum granulosum, acanthosis, keratinocyte hypertrophy
and dermal inflammatory cell infiltration, was observed. In this animal study, no primary irritation, cumulative irritation,
skin sensitization or skin phototoxicity was observed with KP treatment. However, we identified photosensitization as the
underlying cause of KP dermal toxicity. 相似文献

Bacillus thuringiensis (Bt) is the best known and most widely used of all pesticidal microbes. The aim of this study was to assess the toxicity of a new formulation of Bacillus thuringiensis var israelensis SH-14 in rats through acute dermal toxicity, dermal and eye irritation experiments. The acute dermal toxicity and dermal and eye irritation studies were performed using rabbits according to the United States Environmental Protection Agency guidelines 885.3100, 870.2500 and 870.2500, respectively. The skin sensitization study was carried out in accordance to the EPA OPPTS 870.2600 using guinea pigs. There was no mortality and no evidence of treatment-related toxicity in acute dermal toxicity test. No dermal responses, including erythema/eschar or edema, were found in rabbits treated with the new formulation of Bti SH-14. Minimum response was observed after eye application of test substance. No skin sensitization reactions were observed after the challenge with the new formulation of Bti SH-14 in the Bti SH-14-treated guinea pigs. In summary, the present study demonstrated that the new formulation of Bti SH-14 is not acutely toxic via dermal route, has low eye irritation and would not cause dermal irritation or hypersensitivity to tested animals. 相似文献
