Purpose: The purpose of this study is to investigate the healing impact of an ointment derived from the Alkanna tinctoria plant upon Pseudomonas aeruginosa-induced infections. Material and Methods: In this study, 18 male adolescent rats (mean age 6 weeks) weighed an average of 180 g were used. Animals were divided into 3 groups. Group 1: Control group (consisting of burns, no treatment was done), Group 2 (P. aeruginosa): Burn was created and infected with P. aeruginosa, Group 3 (Cream): P. aeruginosa was used to infect the burns area and the herbal mixture was administered twice a day, once in the morning and once in the afternoon. Under anesthesia, the backs of the rats were shaved, and a specially produced steel bar with a diameter of 1*1 cm was immersed in boiling water for 15 seconds before being applied to their backs for 20 seconds. The burned area was subsequently infected with the ATCC Pseudomonas aeruginosa strain, and samples were collected 24 hours later. To detect bacterial growth in this area, the samples were inoculated on blood and EMB (Eosin Methylene Blue) media in a microbiology laboratory. After inoculation, the animals were placed in separate sterile cages and randomly divided into three groups. Once the growth was observed, the tissue and blood samples were harvested from the rats on the 2nd, 7th, 14th, and 21st days. Results: Epithelial regeneration in this group was more prominent. Vascularization was remarkable on the 2nd day, especially in the group in where we induced a burn and applied the ointment. VEGF levels increased more in the ointment group than in that of others. On the 2nd day of the study, the average bacterial count was 105 in sample of both 2nd and 3rd groups. At the end of the study, while the average of bacterial count was increased in the 2nd group, the average of bacterial count was decreased in the 3rd group. Conclusion: It was concluded that the ointment obtained from A. tinctorial successfully repaired the epithelial tissue and contributed to the healing of wounds by modifying increasing VEGF in the blood. However, further research is needed before this ointment can be highly recommended for therapeutic usage

Aim: Antibiotic resistance studies about the Streptococcus have a great importance for the treatment of especially child throat infections in terms of public health and rational antibiotic use. For this purpose, we aimed to identify the macrolide resistance genes mef(E) and erm(B). Material and Method: The throat culture samples taken from 51 children presenting to the hospital with the complaint of sore throat were evaluated in the laboratory, and S. pyogenes was diagnosed using tests; gram staining, catalase, bacitracin and PYR. Susceptibility profile was determined with the Kirby-Bauer disk-diffusion method and minimum inhibitor concentration(MICs) of erythromycin and clindamycin was determined by VITEK 2 System. Results: S. pyogenes was possible macrolide resistance genes of mef(E) and erm(B) was determined by PCR. Macrolide resistance in S. pyogenes are determined in 51 pateients as follows; benzylpenicillin 0%, erytromycin 74.5%, clindamycin 31.4%. In patients with S. pyogenes, the genetic determinants of macrolide resistance mef(E) and erm(B) genes was investigated with the PCR method using primers specific to each gene. Total of 48% of the isolates (n=24) were positive for erm (B), 10% (n=5) for mef(E), in 42% (n=21) of the isolates both genes were detected. Conclusion: The results of our study show that macrolid resistance genes were found in five of the patients evaluated. When the anamnesis of these patients was examined, it was determined that there were patients that frequently presented to the hospital with throat infections and experienced re-infection within a few weeks after receiving treatment.
