  • To investigate the effect of chlorhexidine gluconate and povidone iodine on wound healing, their antimicrobial activity and their effects on wound contraction in rabbits were studied. Staphyococcus aureus (1${\times}$10$\^$7/) was inoculated on the full thickness skin defects (2${\times}$2cm) on the back. Antiseptics were applied on the defects 2 hours after Inoculation. The defects were swabbed for bacterial culture 24 and 48 hours after the application of antiseptics. Percentage of wound contraction, based on wound area measured on the day of surgery was calculated for each wound on days 1,7 and 14. The 0.5% chlorhexidine gluconate solution had more effective antimicrobial activity against Staphyococcus aureus in wounds than 0.05% chlorhexidine gluconate solution (p<0.05), and povidone iodine solution and saline (p<0.01). Percentages of wound contraction were not significantly different among different dilutions of the antiseptics and saline. Present study indicated that the antimicrobial activity of chlorhexidine gluconate in wound was superior to that of povidone iodine.

  • This study determined the effect of postpartum intrauterine infusion of povidone-iodine solution on the subsequent reproductive performance in dairy cows. Six hundred and fifty-eight dairy cows that were around week 4 postpartum were randomly divided into two groups: (1) Cows in treated group received an intrauterine infusion of 100 to 150 ml 2% povidone-iodine solution (treated group, n=269), or (2) Cows that received no treatment were served as the controls (control group, n=389). The cows were bred at observed estrus more than 50 days after calving. Artificial insemination (AI) was done according to the a.m.-p.m. rule. The conception to AI was determined per rectum 60 days after AI by both ultrasonographical observation and manual palpation. The intervals from calving to first service and conception ($94.2{\pm}2.7$ and $144.1{\pm}4.1$ days vs. $88.0{\pm,}2.1$ and $143.5{\pm}4.6$ days, respectively), number of services per conception ($2.0{\pm}0.1$ vs. $2.1{\pm}0.1$), and cumulative pregnancy rates within 90 and 150 days postpartum (31.9 and 61.7% vs. 29.7 and 62.1%) did not differ between the control and treated groups (P>0.05), while conception rate at first service was lower (P<0.05) in the treated group (40.5%) than in the control group (49.4%). Additionally, we could not find any effect of intrauterine infusion of povidone-iodine solution according to cow parity or calving season on the reproductive performance. These results indicate that intrauterine infusion of povidone-iodine solution at week 4 postpartum does not affect the subsequent reproductive performance in dairy cows.

  • In the extremity surgery, pneumatic tourniquet and povidone-iodine solution are commonly used to provide an aseptic, bloodless field, and their complication rate has remained low. However, chemical burn under tourniquet has been rarely reported. Patients sustained burn injuries over the dependent, weight-bearing regions such as posterior neck, back, buttocks and posterior thighs. This rare adverse complication occurred in a 22-year-old man who underwent modified Brostrom operation with arthroscopic os trigonum excision. 10% povidone-iodine was used as topical antiseptic, and full thickness burn occurred underneath the area of tourniquet application. Main causes of povidone-iodine related chemical burn are considered maceration, irritation of the skin, long term use of the tourniquet and pressure. To reduce the complications like chemical burn, awareness of the risk and the possible pathogenesis as well as the preventive measures is important in surgical practice.

  • Delayed healing associated with distal limb wounds is highly challenging in equine clinical practice. This study aimed to evaluate healing rates between chronic non-granulating wounds of horse distal limbs that were treated with maltodextrin/ascorbic acid gel alone or in combination with povidone-iodine 1% solution and those treated with povidone-iodine 1% only throughout the study period (35 days) in clinical settings. The study was conducted on 18 adult horses (3-15 years old). Based on the treatment regimen utilized, the horses were divided into three groups (n = 6), with each group having a similar mean wound area. The percentages of wound contraction, epithelialization, and overall wound healing were determined weekly for each wound. By the end of the study, the total wound healing percentage was significantly increased between the study groups (p < 0.05). The use of maltodextrin/ascorbic acid gel resulted in considerable wound contraction, rapid epithelialization, and complication-free wound healing. Based on the findings of this study, maltodextrin/ascorbic acid gel, independently or in combination with a 1% povidone-iodine solution, might be applied as a safe and effective wound healing promoting agent in horses with chronic non-granulating wounds.

  • Clostridium perfringens (C. perfringens) and Mycobacterium fortuitum (M. fortuitum) are associated with considerable diseases in animals and human. In this study, the disinfection efficacy of a commercial disinfectant composed to povidone-iodine (PVI) was evaluated against C. perfringens and M. fortuitum. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to C. perfringens and M. fortuitum for 30 min at $4^{\circ}C$. The disinfectant and test bacteria were diluted with hard water (HW) or organic matter suspension (OM) according to treatment condition. On HW condition, the bactericidal activity of the disinfectant against C. perfringens and M. fortuitum was 50 and 80 fold dilutions, respectively. On OM condition, the bactericidal activity of the disinfectant against both C. perfringens and M. fortuitum was 15 fold dilutions. As the disinfectant composed to PVI possesses bactericidal efficacy against C. perfringens and M. fortuitum, the disinfectant solution can be used to control the spread of bacterial diseases.

  • Povidone-iodine (PVP-I, Betadine) has many advantages as a disinfectant solution for preoperative preparations, especially for oral surgery. It is widely used because of its low toxicity and excellent bactericidal effect. The authors report a case of pneumonia secondary due to the aspiration of PVP-I, which was used as an oral disinfectant. We present a case of aspiration pneumonia that resulted from the careless use of PVP-I during preoperative preparation. The patient was a 10-month-old female scheduled for elective surgery to correct a complete cleft of secondary palate. During the preparation of the oral cavity for that cleft palate patient, PVP-I was incidentally aspirated to the airway. The lung resistance was noted with positive pressure and pneumonic infiltration on chest radiograph was seen. The operation was postponed and the patient underwent respiratory care. Three months later, elective palatoplasty under general anesthesia was performed without complication. Based on the experiences of this case, the authors advise that throat-packing should be placed before oral preparation to prevent serious pulmonary complications.

  • Dental practice can produce and spread some infectious diseases from patients to dentist, dental assistant, and dental labors. One possible method for preventing these cross-contamination is to immerse dental impression in chemical disinfectants. So for many investigators studied on the dimensional changes of dental impressions and on the surface qualities of stone casts made from impression following immersion in disinfectants. This study was proposed to evaluate some popular impression disinfectant combination from the point of dimensional stability. Impression was taken from dental arch-shaped metal model. Irreversible hydrocolloid and 3 elastomers(polyvinyl siloxane, polysulfide, polyether) were immersed in 3 disinfectants (2% glutaraldehyde, 1% povidone-iodine, 0.5% sodium hypochlorite) for 10 minutes and measured both cross-arch and anterior-posterior distance under stereo microscope to evaluate dimensional change. The results obtained were as follows: 1. Dimensional changes of irreversible hydrocolloid impression was statistically different in cross-arch and anterior-posterior distance when immersed in 2% glutaraldehyde solution and in anterior-posterior distance when immersed in 0.5% sodium hypochlorite solution from control group (p<0.05). 2. Dimensional changes of polyvinyl siloxane and polysulfide impression were not statistically different from control group (p>0.05). 3. Dimensional changes of polyether impression was statistically different in cross-arch distance when immersed in 0.5% sodium hypochlorite solution and in anterior-posterior distance when immersed in 1% povidone-iodine solution from control group (p<0.05). 4. In all cases, dimensional changes were less than 0.1% from the original dimension and concluded clinically acceptable.

  • The objective of this study was to evaluate the effects of several different commercial disinfectants on the embryogenic development of Ascaris suum eggs. A 1-ml aliquot of each disinfectant was mixed with approximately 40,000 decorticated or intact A. suum eggs in sterile tubes. After each treatment time (at 0.5, 1, 5, 10, 30, and 60 min), disinfectants were washed away, and egg suspensions were incubated at $25^{\circ}C$ in distilled water for development of larvae inside. At 3 weeks of incubation after exposure, ethanol, methanol, and chlorohexidin treatments did not affect the larval development of A. suum eggs, regardless of their concentration and treatment time. Among disinfectants tested in this study, 3% cresol, 0.2% sodium hypochlorite and 0.02% sodium hypochlorite delayed but not inactivated the embryonation of decorticated eggs at 3 weeks of incubation, because at 6 weeks of incubation, undeveloped eggs completed embryonation regardless of exposure time, except for 10% povidone iodine. When the albumin layer of A. suum eggs remained intact, however, even the 10% povidone iodine solution took at least 5 min to reasonably inactivate most eggs, but never completely kill them with even 60 min of exposure. This study demonstrated that the treatment of A. suum eggs with many commercially available disinfectants does not affect the embryonation. Although some disinfectants may delay or stop the embryonation of A. suum eggs, they can hardly kill them completely.

  • Salmonella spp. and Brucella spp. are associated with considerable diseases of both humans and animals. In addition, these microorganisms cause the economic loss in animal farming and food industry. In this study, the disinfection efficacy of a commercial disinfectant, composed to povidone-iodine was evaluated against S. typhimurium and B. ovis. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to test bacteria for 30 min at $4^{\circ}C$. The disinfectant and test bacteria were diluted with hard water (HW) or organic matter suspension (OM) according to treatment condition. On HW condition, the bactericidal activity of the disinfectant against S. typhimurium and B. ovis was 400 and 150 fold dilutions, respectively. On OM condition, the bactericidal activity of the disinfectant was 5 and 20 fold dilutions against S. typhimurium and B. ovis, respectively. As the disinfectant composed to povidine-iodine possesses bactericidal efficacy against animal pathogenic bacteria such as S. typhimurium and B. ovis, the disinfectant solution can be used to control the spread of bacterial diseases.
