  • Granulocyte colony-stimulating factor (G-CSF) is used for heart failure therapy and promotes myocardial regeneration by inducing mobilization of bone marrow stem cells to the injured heart after myocardial infarction; however, this treatment has one weakness in that its biological effect is transient. In our previous report, we generated 5 mutants harboring N-linked glycosylation to improve its antiapoptotic activities. Among them, one mutant (Phe140Asn) had higher cell viability than wild-type hG-CSF in rat cardiomyocytes, even after treatment with an apoptotic agent ($H_2O_2$). Cells treated with this mutant significantly upregulated the antiapoptotic proteins, and experienced reductions in caspase 3 activity and PARP cleavage. Moreover, the total number of apoptotic cells was dramatically lower in cultures treated with mutant hG-CSF. Taken together, these results suggest that the addition of an N-linked glycosylation was successful in improving the antiapoptotic activity of hG-CSF, and that this mutated product will be a feasible therapy for patients who have experienced heart failure.

  • Radioiodide uptake in thyroid follicular epithelial cells, mediated by a plasma membrane transporter, sodium iodide symporter (NIS), provides a first step mechanism for thyroid cancer detection by radioiodide injection and effective radioiodide treatment for patients with invasive, recurrent, and/or metastatic thyroid cancers after total thyroidectomy. NIS gene transfer to tumor cells may significantly and specifically enhance internal radioactive accumulation of tumors following radioiodide administration, and result in better tumor control. NIS gene transfers have been successfully performed in a variety of tumor animal models by either plasmid-mediated transfection or virus (adenovirus or retrovirus)-mediated gene delivery. These animal models include nude mice xenografted with human melanoma, glioma, breast cancer or prostate cancer, rats with subcutaneous thyroid tumor implantation, as well as the rat intracranial glioma model. In these animal models, non-invasive imaging of in vivo tumors by gamma camera scintigraphy after radioiodide or technetium injection has been performed successfully, suggesting that the NIS can serve as an imaging reporter gene for gene therapy trials. In addition, the tumor killing effects of I-131, ReO4-188 and At-211 after NIS gene transfer have been demonstrated in in vitro clonogenic assays and in vivo radioiodide therapy studies, suggesting that NIS gene can also serve as a therapeutic agent when combined with radioiodide injection. Better NIS-mediated imaging and tumor treatment by radioiodide requires a more efficient and specific system of gene delivery with better retention of radioiodide in tumor. Results thus far are, however, promising, and suggest that NIS gene transfer followed by radioiodide treatment will allow non-invasive in vivo imaging to assess the outcome of gene therapy and provide a therapeutic strategy for a variety of human diseases.

  • A 6-month-old male Poodle was referred with chief complaint of dysponea and cough. Cyanosis was not detected. This dog was diagnosed as a case of canine patent ductus arteriosus (PDA) by X-ray and ultrasonography. Diuretics and bronchodialators were administered for 4 weeks. Clinical symptoms were not improved. Thoracotomy was done at right recumbent position. The length of ductus arteriosus was 8 mm and the diameter was 6 mm, respectively. Double ligation was performed in surgery. Continuous cardiac murmur, cough and strong femoral pulsation were disappeared after surgery. The diameters of the pulmonary artery and vein found to normal by X-ray on 10 days after operation. The diameter of the aorta measured to be larger than that of the main pulmonary artery by ultrasonography. The fractional shortening (FS) on 10 days after surgery was 17.32% by ultrasonography. The needle-acupuncture therapy was used in acupoints BL-15 as local point plus PC-6, HT-7 and HT-5 as distant points for 3 days (15 min/once/a day). The FSs were increased to 21.31% and 29.44% at 1 and on 3 days after acupuncture, respectively. The present patient was a case of typical canine PDA that showed favorable therapeutic responses by surgery combined with needle-acupuncture treatment.

  • Low-level laser therapy or photobiomodulation (LLLT/PBM) therapy has been widely applied to enhance and accelerate the recovery of oral mucositis. This study investigates the documented effect of LLLT on oral mucositis caused by chemotherapy. This review appraises 6 animal studies and 12 clinical studies published in the Pubmed database during the past 10 years, related to the application of LLLT for the treatment of mucositis. Despite varied parameters and diverse conditions, the assessed articles indicate that application of LLLT on oral mucositis using near-infrared wavelengths is prophylactic, reduces pain, and enables a rapid recovery. Various combined treatments were also identified among the published papers, which further establishes the efficacy of LLLT as a viable treatment.

  • Photobiomodulation (PBM) therapy has been investigated to enhance and accelerate the recovery of injured peripheral nerves. Based on the wide range of benefits of PBM therapy and its clinical relevance, this study reviewed the efficacy of PBM in injured facial nerves. The search was performed in the PubMed database to find relevant articles published over the last 10 years. Four animal studies, two randomized controlled studies, one case series, and five case reports were reviewed. Despite the various parameters, functional analysis showed that PBM therapy using near-infrared irradiation has beneficial effects on the recovery of the acute phase of the damaged facial nerve, especially when related to faster functional improvement. There were no reported adverse effects of PBM therapy.

  • Purpose : The purpose of this study is to investigate how the existence of companion animals and the type of companion animals affect the quality of life and emotional stability of adults in their 20s. Methods : The subjects of this study were adults in their twenties living in Busan who could understand the method of this study. The survey method was conducted with a questionnaire, consisting of 4 questions on general characteristics, 26 questions on quality of life, and 20 questions on emotional stability for a total of 50 questions. An independent t-test and one-way ANOVA were used to verify the difference in quality of life and emotional stability according to general characteristics. Results : As a result of analyzing the difference in the quality of life of the study subjects, the case of having a companion animal scored statistically significantly higher in the satisfaction of the physical domain, psychological domain, living environment domain, overall quality of life domain, and social domain. In addition, there was a statistically significant difference in the case of companion animals according to the type of companion animal. However, there was no statistical significance in the analysis of differences in emotional stability of study subjects according to the presence or absence of companion animals. Conclusion : This study was conducted with 400 adults in their twenties to determine the effects of the presence and absence and type of companion animals on the quality of life and emotional stability of adults in their twenties. As a result, the group with companion animals showed higher satisfaction scores than the group without companion animals in terms of quality of life. This suggests that raising companion animals for adults in their 20s has a positive effect on improving their quality of life. Therefore, it can be recommended for the physical, psychological, and social health of adults in their 20s.

  • Animal symbols exert a profound influence on humans. This can be likened to homeopathic magic, with its source tied to the symbol. It has been believed that consuming an animal or crafting items from its parts would imbue humans with the creature's powers, thereby enhancing its symbolic significance over time. An animal can have various symbolic meanings, and among them, those related to healing have been adopted as folk remedies. Therefore, in this study, we would like to examine an example in which animals were used in folk therapy as a symbol of healing in traditional Korean medicine through "Donguibogam(東醫寶鑑)". In this context, 'healing' not only pertains to direct cures but also encompasses the use of amulets to fend off afflictions and bolster one's immunity. By looking at animals that have traditionally been used in folk remedies, it is possible to reaffirm the role of animals as healing symbols and to find ways to effectively use animal symbols to enhance the healing effect in the future by recognizing their value.
