ABSTRACT

ABSTRACT The present study was designed to investigate the effect of FPZ, a total flavonoids ointment topical application from Pouzolzia zeylanica var. microphylla (Wedd.) Masam, Urticaceae, on skin infections in mice. FPZ ointment anti-infective effect was investigated on Staphylococcus aureus-induced skin abscess and skin ulcers in mice by evaluating the variation in abscess volume, histopathology of skin tissue and healing rate. Secondary, it is topical anti-inflammatory activities on carrageenan-induced hind paw edema in mice was estimated. Besides, FPZ ointment fingerprint was performed by using ultra-performance liquid chromatography and FPZ ointment chemical constituents were isolated and identified by repeated column chromatograph and spectroscopic methods. The results revealed that FPZ ointment topical application at the concentration of 2.5-10% could attenuate skin abscess and ulcers and accelerate wound healing, as compared with control group treated with vehicle (p < 0.05). The histological analysis indicated that FPZ ointment acted via inflammation inhibition, granulation promotion and epidermis formation. Moreover, FPZ ointment effectively inhibited carrageenan-induced paw edema in a dose-dependent manner, especially 10% FPZ which showed superior activities in comparison with dexamethasone used as reference drug. FPZ ointment topical application showed a significant anti-infective effect against pyogenic bacterial skin infection in mice.

ABSTRACT

Objective To observe the therapeutic effect of hoop circumference drug,Hongzhongxiao tincture,on the treatment of skin abscess in rats under the guidance of defended field theory.Methods Forty SpragueDawley (SD) rats were randomly divided into normal control group,model group,western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group according to the computer generated random number.Subcutaneous abscesses models were reproduced by subcutaneous injection of 1 mL (3-5 × 109 cfu/mL) of staphylococcus aureus,and the normal control group was subcutaneously injected with the same amount of normal saline.After molding,the rats in the model group were treated with normal saline for change of dressing;the western medicine control group was treated with mupirocin ointment for external use;Hongzhongxiao pretreatment group was treated with 2 mL of Hongzhongxiao for dressing 4 hours after the modeling;in Hongzhongxiao treatment group,2 mL dressing was given after the emergence of hard swelling,and the Hongzhongxiao drug range applied was 1 cm over the swelling range.Each group was dressed once daily.The changes of mental state,body weight,skin temperature,range and time of abscess formation,wound ulceration and healing time,transcutaneous oxygen pressure (TcPO2) at the periphery of abscess were observed in each group.Results ① After modeling,the activity of the rats was decreased,the appetite became worse,and the food intake less.Except the normal control group,the rats in other groups had different degrees of mental listlessness.② After 3 days of treatment,the body weight gain of the model group was significantly lower than that of the normal control group (g:8.75 ± 9.85 vs.31.67 ± 7.92,P < 0.01),and continued to 18 days after treatment (g:27.13± 11.70 vs.98.00 ± 8.94);after treatment for 18 days,the body weight gain in the western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group was significantlyhigher than those of model group (g:53.28 ± 19.69,49.12 ± 7.23,44.71 ± 12.42 vs.27.13 ± 11.70,all P < 0.05).③ After 3 days of treatment,the body temperature of the model group was obviously lower than that of the normal control group (℃:33.75 ± 0.68 vs.35.03 ± 0.41,P < 0.01) and continued to 10 days (℃:34.30 ± 0.35 vs.35.03 ± 0.41,P < 0.01).The body temperature of the rats in Hongzhongxiao pretreatment group was significantly lower than that in the normal control group,the model group and the western medicine control group on the 14th day after treatment (℃:33.97 ± 0.83 vs.35.10 ± 0.57,35.01 ± 0.68,35.25 ± 0.23,all P < 0.05).The body temperature of Hongzhongxiao treatment group was significantly higher than that of the Hongzhongxiao pretreatment group (℃:34.87 ± 0.94 vs.33.97 ± 0.83,P <0.05).④ After treatment for 13,15,17 days,the contraction rates of swollen area in western medicine control group,hongzhongxiao pretreatment group and hongzhongxiao treatment group were greater than the rate in model group,and the change was most significant on the 17th day after treatment [(96.37 ± 5.09)%,(92.76 ± 13.56)%,(98.41 ± 3.85)% vs.(77.46 ± 19.07)%,all P < 0.05].⑤ Compared with the model group,the times of abscess localization in the western medicine control group,the Hongzhongxiao pretreatment group and the Hongzhongxiao treatment group was shorter than that in the model group (days:9.28 ± 1.38,7.33 ± 1.97,7.67 ± 1.63 vs.12.63 ± 1.99,all P < 0.05);the time of wound healing in Hongzhongxiao pretreatment group aud Hongzhongxiao treatment group were significantly shorter than those of the model group (days:17.67 ± 1.03,16.83 ± 1.51 vs.19.92 ± 2.33,P < 0.05).⑥ TcPO2 in the Hongzhongxiao pretreatment group was significantly higher than that in the model group on the 7th day after treatment [mmHg (1 mmHg =0.133 kPa):63.33 ± 9.77 vs.39.51 ± 8.42],and the Hongzhongxiao treatment group (44.25 ± 6.41) was significantly lower than that of the Hongzhongxiao pretreatment group,and the Hongzhongxiao treatment group was significantly higher than that of the model group (59.50 ± 7.34 vs.49.52 ± 10.17) on the 14th day after drug application,and the western medicine control group was significantly lower than that of the model group (37.71 ± 5.63 vs.54.33 ± 7.74),the Hongzhongxiao pretreatment group and Hongzhongxiao treatment group were significantly higher than those of the western medicine control group,the difference being statistically significant (all P < 0.05).Conclusions The Hongzhongxiao tincture applied on top and circumferentially around the periphery of the abscess can reduce the local inflammatory response,improve the body weight and mental state,increase the blood supply around wound periphery for anti-infection and anti-inflammation in order to promote the formation of defending field of nursing.Although the early application of Hongzhongxiao tincture cannot reduce the local infectious symptoms and kill the Staphylococcus aureus,it can make skin abscess localization as soon as possible and shorten the wound healing time.

ABSTRACT

Opportunistic infections are common after a renal transplant as a result of immunosuppression. Nocardiosis is a rare but important cause of morbidity and mortality among renal transplant recipi-ents. Nocardiosis is a localized or disseminated infection, which is usually introduced through the respiratory tract resulting in pneumonia, and may develop a disseminated infection, in particular a subcutaneous abscess and/or central nervous system infection. Because effective therapy for these nocardiosis is available, an accurate and timely diagnosis is crucial. However, nocardiosis is an infrequent disease and many physicians are unfamiliar to it. In addition, in the laboratory, cul-tures may be discarded too early, which often delays an early diagnosis and treatment. The authors isolated Nocardia asteroides from an abscess of the skin in a rejected renal allograft patient suffering pneumonia. The patient was successfully treated with trimethoprim/sulfamethoxa-zole.
