  • In this research, a habitat model for Chinemys reevesii is suggested based on the components and variables of the Habitat Suitability Index which was determined through a series of literature researches, site surveys, and behavioral analysis. After reviewing the general habitat requirements, the site surveys(9 reservoirs) from July to December 2010, and the behavioral analysis of five Chinemys reevesii, the relationship between the behavioral and habitat use pattern was evaluated. According to the site surveys and behavioral analysis, the ecological core area(FK 50%) was about 0.96ha on average, the influence area(FK 90%) 4.22ha, and the home range was about $37.75{\pm}17.26m$ on average. As for the habitat use pattern of Chinemys reevesii, it travels through canals, and is influenced by the surrounding land uses. Also when there is a lack of food, the home range increases, and during hibernation, Chinemys reevesii prefers to be in an area within 1~2m range of water shores of fine textured soil and aquatic plants. After analyzing the information, the HSI standard was set and its components were determined as food, sunbathing and cover, aquatic environment, and spatial relationships. And the variables and the ranges of the components was determined as aquatic plant cover(0~49.81%), sandy area($3{\sim}13m^2$) and water velocity(0~60cm/s) etc. Lastly, plans and sections of the habitat model is provided designed according to the information from the researches, and problems to consider during habitat restoration was suggested in order to help understand about Chinemys reevesii habitat.

  • Objectives : The aim of this study is to determine whether Chinemys reevesii Gray pharmacopuncture is a clinically effective treatment for women with knee osteoarthritis. Methods : Female patients with knee osteoarthritis were recruited from May $1^{st}$, 2014 to April $15^{th}$, 2015 at the Department of Acupuncture & Moxibustion Medicine of Dong-Eui University Korean Medical Hospital. Patients were randomly assigned to two groups. 4.0 ml of Chinemys reevesii Gray pharmacopuncture was injected at acupuncture points of the experimental group(n = 24) twice a week for three weeks. The control group(n = 24) received 5 % dextrose injections in order to identically stimulate the same acupuncture points of $ST_{35}$, $ST_{34}$, $SP_9$, $SP_{10}$, $GB_{34}$, $LR_8$, $EX-LE_4$, and $EX-LE_2$. The Short-Form McGill Pain Questionnaire(SF-MPQ), the Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), and the European Quality of Life-5 Dimensions(EQ-5D) were recorded to evaluate treatment efficacy at first visit, after two weeks and four weeks from the initial visit. Results : 40 patients completed the trial. The experimental group showed more significant improvement than the control group in the scores of SF-MPQ, KWOMAC, and EQ-5D. However, there was no significant difference between groups in a few of the assessment scales. Conclusions : Chinemys reevesii Gray pharmacopuncture can be an effective treatment in control of pain, improvement in function and health-related quality of life for women with knee osteoarthritis.

  • This study is to investigate the effects of Chinemys reevesii (CR) on allergic inflammation mechanism related chronic dermatitis. To investigate the effects of CR, we study inhibitory effect of CR on the levels of pro-inflammatory cytokines released from RAW 264.7 cell stimulated with lipopolysaccaride (LPS), and EoL-1, THP-1, Jutkat cell stimulated with Dermatophagoides pteronyssinus (DP), and LPS induced acute inflammatory BALB/c mouse model. CR reduced the levels of IL-$1{\beta}$ released from RAW 264.7 cell stimulated with LPS at 20 ug/ml, 10 ug/ml concentration. CR significantly reduced the levels of MCP-1 released from EoL-1 cell, IL-6 from THP-1 cell, and IL-4, IL-5, TNF-${\alpha}$ from Jutkat cell stimulated with DP at all the concentration. CR significantly reduced the levels of TNF-${\alpha}$, IL-6, IL-$1{\beta}$, in LPS induced inflammatory BALB/c mouse model, in a dose-dependent manner. These results suggested that CR has suppressive effects on pro-inflammatory cytokines in various inflammation related cell lines through the regulation of immune system. CR could be a therapeutic agent for treatment of chronic inflammatory dermatitis in the future.

  • Korean freshwater turtles are divided into native turtles, Chinemys reevesii in Geoemydidae, Pelodiscus sinensis in Trionychidae, and imported turtles, Trachemys scripta elegans, T. s. scripta, Pseudemys rubriventris and Ocadia sinensis. In this study, we determined the distribution of Korean freshwater turtles based on a field study and literature study, and considered the taxonomic position of unidentified native turtles. The study was carried out between May 2010 and November 2011 during the day time, and the capturing tool used to collect turtles consisted of net and metal frame. C. reevesii and P. sinensis were found in 16 and 11 places, respectively. C. reevesii, which inhabits the Korean peninsula, is a taxonomically controversial species, but it is presumed that the turtle belongs to Mauremys. Moreover recent taxonomic studies of the soft-shell turtle have shown that the Korean native species is P. maackii, and P. sinensis was imported from abroad and has been in the natural habitats of Korea since 1970s. The exterior shape and skeletal form of P. maackii and P. sinensis are nearly similar. However, the skin color and yellow spots on the shell could be used to distinguish the two species.

  • The author has observed a reeves turttle (Chinemys reevesii) obtained from a market on Jeonju city, Korea. The turttle laid 5 eggs during the period from 31st Aug. to 5th Sep., 2003. The range of egg sizes was 3.5-3.9${\times}$1.9-2.4 cm and that of egg weights, 7.2-10.9 g. It seems to be difficult to distinguish the reeves tuttle eggs from the red-eard tuttle (Pseudemys consina consina) eggs because they are so similar each other in size and shape. He could not hatch out the reeves tuttle eggs.

Crude drugs exerting over 30 % of in Chinemys reevesii (Gray)hibition on platelet aggregation induced by ADP were Ganoderma japonicum (Fr.) Lloyd., Panax ginseng C. A. Mey., Gastrodia elata Bl., Thea sinensis, Chinemys reevesii (Gray), Cuscuta chinensis Lam., Cervus nippon Temminck., Biota orientalis (L.) Endl., Coriolus versicolor, Cinnamomum cassia Presl., Sophora flavescens Ait., Amomum villosum Lour., Carthamus tinctorius L., Rubus chingii Hu., Poria cocos (Schw.) Wolf., Laminana japonica Aresch., Ligustrum lucidum Ait., Angelica sineusis (Oliv.), Cyperus rotundas L., Ginkgo biloba L., Zingiber officinale Rosc., Prunus persica (L.) Batsch., Schizandra chinensis (Turcz.) Baill. and Plantago asiatica L.. 2. Of crude drugs having showed over 50% of inhibitory effect on platelet aggregation, at the concentration of $100{\mu}g/m{\ell}$, the inhibitory rates were 82.2% in Ganoderma japonicum (Fr.) Lloyd., 55% in Panax ginseng C. A. Mey., 50.8% in Gastrodia elata Bl., while at the concentration of $200{\mu}g/m{\ell}$, antithrombotic rates were 89.4% in Ganoderma japonicum (Fr.) Lloyd., 59.2% in Panax ginseng C. A. Mey., 57.9% in Thea sinensis, 52.7% in Gastrodia elata Bl.. These results suggest that the study sholuld be necessary on antithrombotic effect of solvent fractions of Ganoderma japonicum (Fr.) Lloyd., Panax ginseng C. A. Mey., Gastrodia elaha B1. and Thea sinensis and isolation of effective compound from above drugs.

  • The shell of Reeve's turtle has been used as a traditional folk medicine in Korea. We produced a hot water extract from Reeve's turtle shell according to the traditional medical practice. To release bioactive peptides, the hot water extract was enzymatically hydrolyzed with various proteases, and the free radical scavenging activity of the hydrolysate was investigated against 1,1-diphenyl-2-picryl-hydrazyl (DPPH), hydroxyl and peroxyl radicals. The free radical scavenging activity of the enzymatic hydrolysates varied from 1 to 79% depending on the enzymes, free radical species, and concentration. The $EC_{50}$ values demonstrated that the enzymatic hydrolysates of hot water extract from the shell of Reeve's turtle are potential antioxidants.

  • In this study, we evaluated the distribution, habitat characteristics, and diet of two Korean freshwater turtle species (Chinemys reevesii, Pelodiscus sinensis) and an invasive turtle species (Trachemys scripta elegans) in the area surrounding the Seomjin River and the Nam River. We surveyed basking turtles in multiple locations along a 48-km stretch of the Seomjin River and in 99 reservoirs distributed along the Seomjin and Nam rivers from June to September, 2009. We observed 8 and 6 red-eared turtles in 3 reservoirs and at 3 sites in the Seomjin River, respectively, and 33 Reeve's turtles in 9 reservoirs. There were also 28 and 16 mud turtles detected at 15 sites along the Seomjin River and in 8 reservoirs, respectively. Among the 14 biotic and abiotic habitat characteristics that might influence the abundance of freshwater turtles in reservoirs, only the distance between a reservoir and the nearest residential areas was correlated negatively with abundance. With regard to the diet, all Reeve's and red-eared turtles investigated were determined to forage on water snails. Some turtles also foraged on vegetation and aquatic invertebrates. Additionally, we found fish in the stomach of one of the Reeve's turtles, and dragonflies in the stomachs of two red-eared turtles.
