Skin Toxicity of Wufang Babu Ointment to Zebrafish

[Objectives]Using wild-type AB strain of zebrafish as experimental animal,this study investigated the damaging effect of Wufang Babu Ointment on skin cells,in order to evaluate the skin toxicity of Wufang Babu Ointment.[Methods]Wild-type AB strain of zebrafish with an age of 2 d were taken and fed in different concentrations of Wufang Babu Ointment solution for 24 h.The number of deaths in each group of zebrafish was recorded,and the mortality rate was calculated.Using Origin 8.0 software,the maximum non lethal concentration(MNLC)was simulated.Zebrafish raised in different concentrations of Wufang Babu Ointment solution for 24 h were placed under an anatomical microscope for taking photos,to analyze and calculate the incidence of skin damage in zebrafish.Based on the statistical analysis results of this indicator,the skin toxicity of Wufang Babu Ointment was evaluated.[Results]The MNLC of Wufang Babu Ointment on zebrafish was 671μg/mL;Wufang Babu Ointment can induce skin damage at the concentrations of 224μg/mL(1/3 MNLC)and 671μg/mL(MNLC).[Conclusions]Wufang Babu Ointment had certain skin toxicity to zebrafish.

Ototoxicity of povidone-iodine——A case report

Objective: The ototoxicity of povidone-iodine has been documented in animal studies. However, there is limited evidence of these ototoxic effects in humans. This is the first report to show the ototoxic effects of povidoneiodine in a human subject.Patient: A 36-year-old woman came to our hospital complaining of left unilateral persistent hearing loss. One month before presentation, her child had accidentally struck her on her left ear. She applied approximately three drops of povidone-iodine(10% weight/volume) into her left auditory canal. Immediately after application, she felt severe pain and vertigo. An audiogram revealed severe left unilateral sensorineural hearing loss. Magnetic resonance imaging showed mild enhancement of the left vestibule and basal turn of the left cochlea.Conclusions: Even a single application of povidone-iodine could cause significant hearing loss and disequilibrium. It should, therefore, be used with caution.

Evaluation of a povidone-iodine and chitosan-based barrier teat dip in the prevention of mastitis in dairy cows

Postmilking teat dip is an important tool used to prevent mastitis in the modern dairy industry.In this study,we evaluated the in vitro and in vivo efficacies of a barrier teat dip containing povidone-iodine and chitosan for the prevention of mastitis.In experiment 1,we evaluated the antibacterial effects of chitosans with different molecular weights against six mastitis-causing bacteria based on the minimal inhibitory concentration test.The results showed that 50 k Da chitosan had the maximum antibacterial activity compared with 5,150 and 350 k Da chitosans.In experiment 2,the inhibition zone test indicated that the barrier teat dip with 4.0%povidone-iodine and 1.0%chitosan had higher(P<0.05)in vitro antibacterial efficacy against most tested mastitis-causing bacteria than the barrier teat dip with 4.0%povidone-iodine and no chitosan.In experiments 3 and 4,we evaluated the efficacies of two postmilking teat dips,1)a barrier teat dip containing 1.0%chitosan and 4.0%povidone-iodine and 2)a conventional nonbarrier product containing 10%povidone-iodine in a field trial at two commercial dairy herds(1 and 2).A 56-d split-udder experiment(experiment 3)was conducted using 47 lactating Chinese Holstein cows in herd 1.Both left teats were immersed in barrier postmilking dip,and both right teats were dipped with nonbarrier postmilking dip.During a 56-d split-herd experiment(experiment 4),a total of 139 lactating Chinese Holstein cows from herd 2 were allocated to two groups:1)all teats of 67 cows were dipped in the nonbarrier teat dip,and 2)all teats of 72 cows were dipped in the barrier teat dip.Milk samples were collected and analyzed for somatic cell count(SCC),fat content,protein content,and fat-to-protein ratio prior to the start of sampling(0 d),and at 28 and 56 d after initiation.Bacteriological analysis was only performed on milk samples with SCC≥200000 cells mL^(-1).In experiment 3,no differences(P>0.05)in SCC,somatic cell score(SCS)or other milk quality indicators were observed between nonbarrier and barrier teat dip treatment teats throughout the experiment.At the end of experiment 4,compared with nonbarrier teat dip group,a reduction(P<0.05)of 29%was observed for subclinical mastitis infection prevalence in the barrier teat dip group.In the barrier teat dip group,the subclinical mastitis infection prevalence on 56 d was lower(P<0.05)than 0 d.No differences(P>0.05)in milk qualities or clinical mastitis incidence were detected between groups.Bacteriological analysis demonstrated that the barrier product containing povidone-iodine and chitosan reduced the subclinical mastitis infection prevalence induced by mastitis pathogens.This effect was mainly due to the reductions in Klebsiella pneumoniae,Pseudomonas aeruginosa,and Escherichia fergusonii infections.Overall,the data indicated that a barrier teat dip containing 4%povidone-iodine and 1%chitosan was more effective than 10%povidone-iodine in preventing subclinical mastitis.

Successful prolonged cardiopulmonary resuscitation after intraoperative cardiac arrest due to povidone-iodine allergy: A case report

BACKGROUND Iodophor(povidone-iodine)is widely used clinically because of its broadspectrum antibacterial effects.Although extremely rare,it may cause anaphylactic shock,which itself carries the life-threatening risk of cardiac arrest.CASE SUMMARY We present a case in which a patient with postoperative infection went into anaphylactic shock and cardiac arrest caused by povidone-iodine during secondary surgery.The patient was successfully resuscitated by 2 h of cardiopulmonary resuscitation.CONCLUSION This is the first known case of cardiac arrest caused by povidone-iodine allergy.

Effects of Povidone-Iodine or Ethanol Exposure on Bone Formation at the Osteotomy Site of the Proximal Tibia in Rats

Background: Povidone-iodine (PVI) irrigation is currently used to decrease the frequency of postoperative surgical site infections. Ethanol (EtOH) is sometimes applied to prevent local recurrence after curettage of benign bone tumors. However, the effects of PVI and EtOH on surrounding soft tissue and on bone union are unclear. The purpose of this study was to determine whether PVI or EtOH adversely affects the cancellous bone healing of the osteotomy site at the proximal tibia in rats. Methods: A cancellous bone osteotomy was performed at the right proximal tibia in 4-month-old, female, Sprague Dawley rats. Vehicle, 10% PVI, or 95% EtOH-soaked gauze was inserted into the osteotomy site and maintained for 6 minutes. The rats were euthanized 2 or 4 weeks after the osteotomy. Results: Two weeks after treatment, the bone union rate was significantly higher in the vehicle group than in the PVI group and the EtOH group (p < 0.001). However, the bone union rate was not significantly different between the PVI and EtOH groups. There was no significant difference among the three groups in the bone union rate 4 weeks after treatment. Conclusion: PVI or EtOH delayed bone union of the cancellous bone osteotomy site of the proximal tibia in the early phase (2 weeks), but not at 4 weeks, in rats.

Exploring the mechanism of moist exposed burn ointment for the treatment of diabetic ulcer based on network pharmacology and molecular docking

Objective:To discuss the main active components and potential mechanisms of moist burn ointment in the treat-ment of diabetic ulcer were discussed by network pharmacology and molecular docking technology.Methods:Based on the TC-MSP database,the main active components and targets of MEBO were screened.The targets related to diabetic ulcers were searched from GeneCards,OMIM,PharmGkb,TTD,and DrugBank databases.The STRING 11.5 database was used to con-struct a protein-protein interaction(PPI)network to screen the core targets.The'drug-target-disease'network diagram was made in Cytoscape 3.8.2 software to screen the core active components.GO enrichment analysis and KEGG pathway enrichment analysis were performed using R language software.Finally,molecular docking was used to preliminarily verify the screening results.Results:A total of 37 active components of MEBO were screened to map 100 targets,5527 targets for diabetic ulcer dis-ease,and 77 intersection targets.PPI network topology analysis suggested that TP53,TNF,HSP90AA1 and other targets were key targets;the network diagram of ‘drug-target-disease’showed that acacetin,wogonin,quercetin,and rutaecarpine were the core active ingredients.GO function analysis mainly involved angiogenesis,ion transport,diameter regulation,cytokine receptor binding,and other processes.KEGG enrichment analysis mainly included PI3K-Akt,AGE-RAGE,and other signaling pathways.Molecular docking showed that the core active ingredients and key targets had good docking activity.Conclusion:The treatment of diabetic ulcer with MEBO is the result of multi-component,multi-target,and synergistic regulation,which provides a theoretical basis for the clinical application of MEBO and the treatment of diabetic ulcer.
