  • Background: It is well known that skin cancer and precancerous disease develop more frequently in patients undergoing solid organ transplantation than normal populations in the normal population in Western countries. However, to date, the clinical and demographic features of skin cancer and precancerous disease after solid organ transplantation are not established in Asian countries. We evaluated the clinical and demographic features of primary skin cancer and precancerous lesions after solid organ transplantation and compared these with the trends observed in Western countries. Methods: We retrospectively reviewed the medical records of patients who underwent kidney, liver, heart, and lung transplantation between January 1995 and April 2017 and who developed skin cancer or precancerous lesions after transplantation. The various lesions observed were squamous and basal cell carcinoma, malignant melanoma, Kaposi sarcoma, Bowen's disease, and actinic keratosis. Results: We identified 4604 patients who received organ transplant. The mean age of patients was 44.8 years (male, 64.6%; female, 35.4%), and the sum of the person-year of observation time was 31,024 person-years. The incidence rate per 100,000 person-years was 29.01 for squamous cell carcinoma, 19.34 for basal cell carcinoma, 6.45 for malignant melanoma 3.22 for Kaposi sarcoma, and 74.17 for Bowen's disease and actinic keratosis. The incidence rate per 100,000 person-years was the highest in patients undergoing heart transplantation (610.50), followed by those who underwent kidney transplantation (136.54) and liver transplantation (90.15). Koreans showed lower incidence rates than those observed in Westerners. Conclusion: The incidence of primary skin cancer and precancerous lesions after solid organ transplantation in Koreans was lower than that in Westerners. Squamous cell carcinoma was the most common skin cancer in patients undergoing solid organ transplantation and the incidence rate of skin cancer and precancerous lesions was the highest in patients undergoing heart transplantation.

  • Objectives: As a general emotion, everyone can temporarily experience depression, but depressive disorder is a disease that excessively affects daily life. Among the various causes of depression, the deficiency of monoamine-based neurotransmitters such as serotonin and epinephrine are considered significant. Thus, antidepressants that target monoamines are used frequently. However, side effects such as nausea, vomiting, insomnia, anxiety, and sexual dysfunction are observed. Thus, it is necessary to develop a new therapeutic agent with fewer side effects. In this study, we investigated the antidepressant effect of JG02, used to treat depression by normalizing the flow of qi (氣) in Korean medicine. Methods: C57BL/6 mice were selected and randomly divided into six groups: normal, control, amitriptyline, and JG02 (50, 125, 250 mg/kg), respectively. Except for normal, depression was induced by applying restraint stress at the same time for six hours daily for 14 consecutive days. Saline, amitriptyline or JG02 samples were orally administered two hours before applying the stress. After that, a forced swimming test and an open field test were performed. Additionally, serum corticosterone, serotonin mRNA, BDNF mRNA, and protein in the hippocampal region were measured and compared. Results: JG02 decreased immobility time rate in the FST and increased the zone transition number and travel distance in the OFT. Also, JG02 inhibited the release of serum corticosterone, and increased serotonin, BDNF gene expression, and BDNF protein in the hippocampus. Conclusions: In this study, JG02 showed significant antidepressant effects on the chronic restraint stress mice model. When further research is performed based on JG02, the development of a new antidepressant is considered highly possible.

  • Objectives : This study is to report a case of otitis media with effusion accompanied by atopic dermatitis improved by Korean medicine monotherapy. Methods : A 31-year-old woman patient visited our clinic for aural fullness, hearing loss, and tinnitus of the left ear on August 14th, 2021. She also had abdominal pain, diarrhea, and general weakness because of side effects of antibiotics. Besides, she had nasal congestion, rhinorrhea, and dry skin. Through otoscopy, her tympanum was fully filled with yellow effusion. She only took Korean medicine therapy including acupuncture and herbal medicine weekly. The treatment continued for about 4 months(total 14 visits) until December 4th, 2021. Otoscopy, numerical rating scale(NRS), scoring atopic dermatitis(SCORAD) index were used to assess the symptoms. Results : On August 30, 2021, her intestinal symptoms improved. The left tympanum was recovered to normal condition as the treatment continued. The effusion disappeared on October 16th, 2021. On November 6th, 2021, peritympanic blood congestion also almost alleviated. Subjective symptoms including aural fullness, hearing loss, and tinnitus disappeared on October 16, 2021. Nasal symptoms and dry skin also improved. The SCORAD index dropped from 15 to 4. Conclusions : These results suggests that otitis media with effusion can be sufficiently managed by Korean medicine therapy. Further, active application of Korean medicine therapy to common otolaryngological diseases is necessary.

  • Objectives : To identify the active ingredient of Poncirus Trifoliata Immaturus and to explore the mechanism expected to potentially act on dermatitis accompanied by pruritus. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of Poinciri Fructus Immaturus. We found the target protein of the selected active ingredient, disease(dermatitis accompanied by pruritus) and fexofenadine. Then we established the network between the proteins which Poinciri Fructus Immaturus and fexofenadine intersected with disease respectively, and the coregene was also extracted. After that, the active pathways in the human body involving the groups and coregenes were searched. Results : Total of 7 active ingredients were selected, and 202 target proteins were collected. There were 756 proteins related to inflammatory skin disease accompanied by pruritus, and 75 proteins were related to fexofenadine. 42 proteins crossed by Poinciri Fructus Immaturus with a disease, and 31 proteins crossed by fexofenadine with a disease. 12 proteins were found as a coregene from the proteins that cross Poinciri Fructus Immaturus and disease. Coregenes are involved in 'Nitric-oxide synthase regulator activity', 'Epidermal growth factor receptor signaling pathway'. 2 groups that extracted are invloved in 'Fc receptor signaling pathway', 'Central carbon metabolism in cancer', 'Phosphatidylinositol 3-kinase complex, class IB', and 'omega-hydroxylase P450 pathway'. Conclusion : It is expected that Poinciri Fructus Immaturus will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied by pruritus in the future. And it is also expected to have a synergy effect with fexofenadine on skin disease.

  • Purpose: Oxidative stress was thought to play a critical role in neurodegenerative disease. Many in vivo and in vitro reports explained the possible pathway of human aging. But in therapeutic aspects, there was no clear answers to prevent aging associated with neural diseases. In this study, we investigated the antioxidant and neuroprotective effects of the Insamyangyung-tang (IYT). Methods: To estimate the antioxidant effects, we carried out 1.1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, 2,2'-azinobis-(3- ethylbenzothiazoline-6- sulfonic acid (ABTS) radical cation decolorization assay, and measurement of total polyphenolic content. To evaluate neuroprotective effect of IYT in vitro. We performed thiazolyl blue tetrazolium bromide (MTT) assay, reactive oxygen species (ROS) creation in SH-SY5Y. Tyrosine hydroxylase (TH) immunocytochemistry, nitric oxide (NO) assay, and TNF-${\alpha}$ assay in primary rat mesencephalic dopaminergic neurons. Results: The $IC_{50}$ values were $571.6{\mu}g/m{\ell}$ and $202.3{\mu}g/m{\ell}$ in DPPH and ABTS assay respectively. Total polyphenolic content was 1.05%. In SH-SY5Y culture, IYT significantly increased the decreased cell viability by 6-OHDA at the concentrations of $10{\mu}g/m{\ell}$ in pre-treatment group, $10-100{\mu}g/m{\ell}$ in post-treatment group, and $100{\mu}g/m{\ell}$ in co-treatment group. The production of ROS induced by 6-OHDA was significantly inhibited in IYT treated group. In mesencephalic dopaminergic cell culture, the IYT group reduced the dopaminergic cell loss against 6-OHDA toxicity and the production of No and TNF-${\alpha}$ at the concentration of $0.2{\mu}g/m{\ell}$. Conclusion: These results showed that IYT has antioxidant and neuroprotectctive effects in the dopaminergic cells through decreasing the production of ROS, NO and TNF-${\alpha}$ which can cause many neurodegenerative changes in brain cell.
