  • Korean ginseng (Panax ginseng) is associated with a variety of therapeutic effects, including antioxidative, anti-inflammatory, vasorelaxative, antiallergic, antidiabetic, and anticancer effects. Accordingly, the use of ginseng has reached an all-time high among members of the general public. However, the safety and efficacy of ginseng in transplant recipients receiving immunosuppressant drugs have still not been elucidated. Transplantation is the most challenging and complex of surgical procedures and may require causation for the use of ginseng. In this regard, we have previously examined the safety, immunological benefits, and protective mechanisms of ginseng with respect to calcineurin inhibitor-based immunosuppression, which is the most widely used regimen in organ transplantation. Using an experimental model of calcineurin inhibitor-induced organ injury, we found that ginseng does not affect drug levels in the peripheral blood and tissue, favorably regulates immune response, and protects against calcineurin inhibitor-induced nephrotoxicity and pancreatic islet injury. On the basis of our experimental studies and a review of the related literature, we propose that ginseng may provide benefits in organ transplant recipients administered calcineurin inhibitors. Through the present review, we aimed to briefly discuss our current understanding of the therapeutic benefits of ginseng related to transplant patient survival.

  • The world's first face transplantation was performed in France, in 2005. Since then, 21 cases of face transplantation have been performed. Face transplantation is one of the most prominent part of composite tissue allotransplantation (CTA) along with hand transplantation. Since these fields are not deal with life-saving organs, there are many arguments about immunosuppression therapy. Recent paradigm of face transplantation shows that surgical ranges are expanded from partial face transplantation to full face transplantation. Most immunosuppression protocols are triple therapy, which consists of tacrolimus (FK-506), mycophenolate mofetil and prednisolone. Anatomical researches, immunosuppression, and immunotolerance take great parts in the researches of CTA. The medical fields directly related to face transplantation are microsurgery, immunology, and transplantation. Nowadays, each field is performed widely. Therefore people, even medical teams think face transplantation could be easily realized, sooner or later. But there are lots of things that should be prepared for not only practice and immunosuppression therapy but also for the cooperation with relevant fields. That's the reason why only 21 cases of face transplantation have been done, while more than 70 cases of hand transplantation have been done in the past years. Especially in Korea, brain death patients are not enough even for organ transplantation and furthermore there are some troubles in taking part in the society of transplantation. Face transplantation has lots of problems concerning variable medical fields, administration, society, ethics, and laws. Therefore, for the realization of face transplantation in Korea, not only medical skills but also political powers are needed.

The Effect of Mixed Aroma Oil with Chamomile, Lavender and Sandalwood on Atopic Dermatitis in NC/Nga Mice (NC/Nga 마우스의 아토피 피부염에 미치는 카모마일, 라벤더, 샌달우드 혼합오일 도포의 치유효과)

  • The effects of aroma mixed oil with Chamomile, Lavender and Sandalwood on atopic dermatitis in NC/Nga mice were examined. The NC/Nga mice were divided into BMAC group, FK 506 Oinment (Tacrolimus Hydrate) group, and CLS group to get curative power of CLS. The amount of total IgE and IgG1 was measured and the severity of atopic dermatitis was assessed by the scoring procedure in NC/Nga mice. Topically applied CLS significantly suppressed the level of serum IgE and IgG1 in NC/Nga mice and FK506, used as reference drugs for atopic dermatitis, also exhibited suppressive effects against level of IgE and IgG1. The level of IgE was lower in the CLS group than in the FK506 group while the serum IgG1 level in the FK506 group was lower than in the CLS group. The treatment with FK506 and CLS reduced the skin inflammation index, especially the severity degree of atopic dermatitis in the skin lesioned NC/Nga mice by naked eyes was improved by treatment of FK506 and CLS. The results suggest that treatment of CLS in NC/Nga mice with atopic dermatitis have an beneficial therapeutic effects on reducing the level of IgE and IgG1 and accelerating repair of skin lesion.

  • Purpose: Survival after liver transplantation (LT) has improved over the years, but infection is still a major complication. We aimed to identify the characteristics of bacterial infections in pediatric LT recipients. Methods: This study is a retrospective review of 189 consecutive children undergoing LT between 2000 and 2015 at a single center. In this study, the incidence of infection was determined for the following periods: within 1 month, between 1-5 months, and between 6-12 months. Patients who underwent liver transplants more than once or multiple organ transplants were excluded. Results: All patients had received postoperative antibiotic for 3 days. Only the maintenance immunosuppression with oral tacrolimus and steroids were performed. As a result, 132 bacterial infections developed in 87 (46.0%) patients (0.70 events per person-year). Bacterial infections occurred most frequently within the first month (n=84, 63.6%) after LT. In the pathogens, Staphylococcus aureus (15.2%), Enterococcus species (15.2%), and Klebsiella species (13.6%) were most common. Regarding the organ infected, bloodstream was most common (n=39, 29.5%), followed by peritoneum (n=28, 21.2%), urinary tract (n=25, 18.9%), and lungs (n=20, 15.2%). We changed prophylactic antibiotics from ampicillin-sulbactam to piperacillin-tazobactam at 2011, October, there were no significant effects in the prevalence of antibiotics resistant bacterial infections. The 1-year mortality was 9.0% (n=17), in which 41.2% (n=7) was attributable to bacterial infection; septicemia (n=4), pneumonia (n=2), and peritonitis (n=1). Conclusions: The incidence and type of bacterial infectious complications after LT in pediatric patients were similar to those of previous studies. Bacterial complications affecting mortality occur within 6 months after transplantation, so proper prophylaxis and treatment in this period may improve the prognosis of LT.
