The present study was conducted in order to get the relationship of heartworm, Dirofilaria immitis and eosinophils in blood of Jindo dogs. Blood samples were taken from 141( man 31, womam 110) of yellow, 44 ( man 17, woman27) of white Jindo dogs in Jindo area. The results obtained in this study were summarized as follows : 1. There were no significant differences of the hematological values in comparison with others reported values, but the mean corpuscular hemoglobin concentration and the number of eosinophils were high in comparison with other reported values. 2. The mean values of total white blood cell count(P<0.05), neutrophil(P<0.05) and monocyte(P< 0.05) were that the yellow dogs and a tendency toward fisher values than the white dogs, but no significant differences were observed. 3. Age-related differences were detected for the total erythrocyte count(P<0.05), hemoglobin content (P<0.001), PCV(P<0.001) and the number of eosinophils(P<0.001). 4. The direct and indirect eosinophil counts were increased with age, there were no significant differences of the values between two groups. 5. Dirofilaria immitis was found in 34(18.4%), increased with age and were relatively significant differences in areas of the 185 Jindo dogs. 6. Survey for hematological values of Dirofilaria immitis infected dogs with direct and indirect method, mean values of eosinophil were 2,788/ ${\mu}l,$ 3,021/ ${\mu}$l, respectively. They showed that eosinophil had a tendency toward higher values than others, but others were no significant differences.

Jindo Hongju is a traditional liquor in Jindo island of Korea. The characteristics of Hongju are its unique flavour by fermetation and red color of gromwell(Lithospermum erythrorhizon) root. However, the evaluation of red pigment is different from one manufactures to other manufactures and from place to place, also the standard method is not established. An attempt has made to compare the quality of gromwell root from different places and to standardize the extracting method. The results obtained from this study are summerized as follow, The chemical properties and composition of gromwell root from Jindo and other areas were compared. There were no difference among the samples in moisture content, content of naphtoquinone derivatives and absoption spectra. These results indicate that the pigments from Jindo and other region products seems to be the same quality. For efficient extraction of gromwell pigment, more than 40% ethanol as solvent and at least 10 hours extraction time was required. According to the visual test for Hongju pigment, the most preferable color was that it shows absorbance of 1.0 (contents of shikonin was 3.90 mg/45% EtOH 20 ml). From this visual test it can be proposed that the may be applied absorbance at 1.0 for the quality control of pigment.

;Jindo Hongju is an unique red-colored traditional distilled wine of Korea. The unique attractive color of Jindo Hongju is due to the pigments of gromwell (Lithospermum erythrorhizon) root, derivatives of naphtoquinone such as shikonin and acetylshikonin. Which are extracted during the distillation process. The attractive color of the gromwell pigments is easily changed to dark red or to brown causing deterioration of the Quality of Jindo Hongju. Due to the discoloration of the pigments and to the limited supply of gromwell roots, some brewers manufacture spurious Jindo Hongju using artificial colorants. This study was performed to devise a simple method of detecting spurious Jindo Hongju products. The color of the gromwell pigments was greatly affected by pH change and the change could be demonstrated by the change of the absorption spectrum. At pH 4.0 the normal pH of Jindo Hongju, the absorption spectra of gromwell pigments and genuine Hongju products showed an absorption maximum of 520 nm. The absorption maximum was shifted to 570 nm and to 616 nm as the pH was raised to 7.0 and 11.0 respectively. This transition due to the pH change was also demonstrated on em chromaticity diagram. The characteristic transition due to pH change of gromwell pigment solution was not observed with an artificial colorant (red No.2) which was suspected to be used in the manufacture of imitation products. The absorption spectra of most of the Jindo Hongju collected from the market were similar to that of the gromwell pigments and showed the characteristic transition due to pH change with the addition of NaOH. However, with a few of the products, the absorption spectra was similar to that of the artificial colorant and the characteristic transition due to pH change was not observed, indicating these products might have been forged. The result of study suggests that the transition of the absorption spectrum and the change of the color due to pH change be used for the detection of imitation products. Farther more, since, at pH above 9.0, the color of the gromwell pigments and genuine Jindo Hongju could be visually differentiated from that of the artificial colorant and forged products, it might be possible that the forged products be easily detected by raising the pH to above 9.0 and visually comparing the color with that of the gromwell pigment at the same pH.me pH.

We surveyed the freshwater invertebrates of Jindo Island twice on July and September 2016, as part of a joint faunal survey conducted to commemorate the 30th anniversary of the Korean Society of Systematic Zoology. Aquatic insects were not included in this study. We found 38 freshwater species from seven phyla: Porifera, Platyhelminthes, Nematomorpha, Mollusca, Annelida, Arthropoda, and Bryozoa. Twenty-one of the 38 species (55.3%) represented the first record of their respective species on Jindo Island. Among these species, a freshwater shrimp-parasitic isopod, Tachaea n. sp., was identified as a new species.

A 10-year-old intact female Jindo dog was presented with a 1-week history of conjunctival redness and ocular discharge in the left eye. There was an absence of menace response, dazzle reflex, and direct pupillary light reflex. Slit-lamp biomicroscopy revealed corneal edema, ciliary flush, and aqueous flare. Intraocular pressure was 68 mmHg. Based on the information available, a diagnosis of glaucoma and uveitis was made. Subsequent histopathologic examination showed the glaucoma was produced by the effects of goniodysgenesis, posterior synechia, and pigment dispersion in the trabecular meshwork. This is the first report of primary glaucoma caused by goniodysgenesis in Jindo dogs.

We generated 16,993 expressed sequence tags (ESTs) from two libraries containing full-length cDNAs from the brain and liver of the Korean Jindo dog. An additional 365,909 ESTs from other dog breeds were identified from the NCBI dbEST database, and all ESTs were clustered into 28,514 consensus sequences using StackPack. We selected the 7,305 consensus sequences that could be assembled from at least five ESTs and estimated that 12,533 high-quality single nucleotide polymorphisms (SNPs) were present in 97,835 putative SNPs from the 7,305 consensus sequences. We identified 58 Jindo dog-specific SNPs in comparison to other breeds and predicted seven synonymous SNPs and ten non-synonymous SNPs. Using PolyPhen, a program that predicts changes in protein structure and potential effects on protein function caused by amino acid substitutions, three of the non-synonymous SNPs were predicted to result in changes in protein function for proteins expressed by three different genes (TUSC3, ITIH2, and NAT2).

Blood type in dogs is based on the antigen present on the red blood cell surface. Dog erythrocyte antigen 1 is a crucial red blood cell antigen in dogs, whereas the dog erythrocyte antigen 7 has been studied in limited dog breeds worldwide. To assess the prevalence of dog erythrocyte antigens 1 and 7 in 11 breeds in the Republic of Korea, 624 dog blood samples were examined for antigen detection. Overall, 520 dogs (83.3%) showed dog erythrocyte antigen 1 expression. The distribution varied from 50.0~100.0% according to the breed. Dog erythrocyte antigen 1-positive blood type was the highest in Chihuahua (100%), followed by Jindo dog (98.5%), and Sapsaree (95.3%). Dog erythrocyte antigen 7 was positive in 125 dogs (20.0%), and the positivity varied from 5.0~42.9% according to the breed. Dog erythrocyte antigen 7-positive blood type was the highest in Beagle (42.9%), followed by Chihuahua (37.5%), and Jindo dog (27.8%). The high prevalence of dog erythrocyte antigen 1 is because of the high proportion of Jindo dog and Sapsaree breeds that were mostly positive for the antigen. The high abundance of these breeds could be due to inbreeding and local breeding in the Republic of Korea. To our best knowledge, this study is the first to report on the prevalence of dog erythrocyte antigens 1 and 7 among various canine breeds in the Republic of Korea. The prevalence data obtained from this study may contribute to baseline information on veterinary transfusion medicine in small animal practice.

In the present study, to explore the current status of mammals that inhabit Jindo Island, Jeollanam-do, South Korea, a survey was conducted from July 6 to July 9, 2016. Using several survey methods, such as Sherman's live trap, footprint, caves, excretions, and road-kill investigations, the mammals observed on Jindo Island were found to be from 5 orders and 9 families, including 12 species in total. Among them, three species of small mammals were Mogera wogura, Crocidura shantungensis, and Apodemus agrarius. Additionally, two legally protected species were found through excretion observations. Lutra lutra and Prionailurus bengalensis, which were designated to endangered wild animal classes I and II, respectively. The survey results can be used as a valuable resource for identifying the distribution and habitat status of mammals in the Jindo-gun area, as well as for building a database for ecosystem preservation.
