  • Lying has been such a wrong act in human society, but at the same time we are perpetrating lying surprisingly often in the interpersonal situation. Like this, between what we think and what we do about telling lie is pretty different, and these differences are came from ambivalent attitudes stemmed from different sources which is divided into the implicit and the explicit attitude. We find manipulative liars by simulated racing task by using virtual environment. Implicit Association Test was applied to them to see implicit beliefs, and used self-reported questionnaires to identify explicit attitude about lying. As a result they could manipulate the explicit measures but could not maneuver their own implicit attraction to lie Liars' deceptive behaviors usually occur in subtle and covert way so that it has been hard to notice and to know what lead them to lie. However, as we know those spontaneous process is linked with deception, triggering them lie, it became no more veiled, unpredictable actions.

  • Since ancient days, domestic horses have been closely associated with human civilization. Today, horse racing is an important industry. Various genes involved in energy production and muscle contraction are differentially regulated during a race. Among them, creatine kinase (CK) is well known for its regulation of energy preservation in animal cells. CK is an iso-enzyme, encoded by different genes and expressed in skeletal muscle, heart, brain and leucocytes. We confirmed that the expression of CK-M significantly increased in the blood after a 30 minute exercise period, while no considerable change was observed in skeletal muscle. Analysis of various tissues showed an ubiquitous expression of the CK-M gene in the horse; CK-M mRNA expression was predominant in the skeletal muscle and the cardiac muscle compared to other tissues. An evolutionary study by synonymous and non-synonymous single nucleotide polymorphism ratio of CK-M gene revealed a positive selection that was conserved in the horse. More studies are warranted in order to develop the expression of CK-M gene as a biomarker in blood of thoroughbred horses.

  • This study was conducted to estimate the effective population size using SNPs data of 240 Jeju horses that had raced at the Jeju racing park. Of the total 61,746 genotyped autosomal SNPs, 17,320 (28.1%) SNPs (missing genotype rate of >10%, minor allele frequency of <0.05 and Hardy-Weinberg equilibrium test P-value of < $10^{-6}$) were excluded after quality control processes. SNPs on the X and Y chromosomes and genotyped individuals with missing genotype rate over 10% were also excluded, and finally, 44,426 (71.9%) SNPs were selected and used for the analysis. The measures of the LD, square of correlation coefficient ($r^2$) between SNP pairs, were calculated for each allele and the effective population size was determined based on $r^2$ measures. The polymorphism information contents (PIC) and expected heterozygosity (HE) were 0.27 and 0.34, respectively. In LD, the most rapid decline was observed over the first 1 Mb. But $r^2$ decreased more slowly with increasing distance and was constant after 2 Mb of distance and the decline was almost linear with log-transformed distance. The average $r^2$ between adjacent SNP pairs ranged from 0.20 to 0.31 in each chromosome and whole average was 0.26, while the whole average $r^2$ between all SNP pairs was 0.02. We observed an initial pattern of decreasing $N_e$ and estimated values were closer to 41 at 1 ~ 5 generations ago. The effective population size (41 heads) estimated in this study seems to be large considering Jeju horse's population size (about 2,000 heads), but it should be interpreted with caution because of the technical limitations of the methods and sample size.

  • Next to performing an expert physical examination, a blood sample submitted for a complete blood count is the most basic tool available to owners or veterinary practitioners. Reference values of complete blood count were determined at 6 different ages in 114 Thoroughbred foals during the second month of life. Hematologic results were as follows: RBC 8.2-10.5 ($10^6/{\mu}l$), Hb 10.9-13.3 (g/dl), HCT 28.2-35.2 (%), MCV 30.7-35.8 (fL), MCH 11.9-13.5 (pg), MCHC 37.9-40.5 (g/dl), RDW 24.5-25.7 (%), PLT 146.3-256.4 ($10^3/{\mu}l$), MPV 6.7-8.3(fL), total WBC 8.1-12.5 ($10^3/{\mu}l$), basophils 0.0 ($10^3/{\mu}l$), eosinophils 0.0-0.3 ($10^3/{\mu}l$), neutrophils 2.4-8.6 ($10^3/{\mu}l$), lymphocytes 1.8-2.9 ($10^3/{\mu}l$) and monocytes 0.0-1.4 ($10^3/{\mu}l$). The results of this study serve as reference ranges for Thoroughbred neonatal foals populations and can be useful for health control, regular examination and pre-sale soundness examination.

  • Macrocyclic lactone resistance has been reported in populations of Parascaris equorum from several countries. A Grant's zebra (Equus burchelli bohmi) was admitted to the Equine Hospital at Jeju Race Park with signs of chronic weight loss and severe depression. Clinical examination revealed tachycardia and dehydration. Over the course of a day, the zebra suffered from severe abdominal pain and subsequently died. Prior to admission, the zebra had received prophylactic anthelmintic treatment with ivermectin 3 times at 3-month intervals and was dewormed with ivermectin 30 days prior to the onset of depression. At necropsy, there were masses of ascarids in the stomach and small intestine, and intestinal perforation. There are many reports of ivermectin-resistant P. equorum in horses. However, anthelmintic resistance has not been formally demonstrated in zebras. This report describes diagnosed case of gastrointestinal impaction and intestinal perforation by P. equorum in an adult zebra. We suspect that ivermectin-resistant P. equorum larvae were the cause.

  • A 4-month-old female thoroughbred foal was presented with large mass on mandibular gingiva. The enlarged mass was firm and yellowish pink in color, and occupied the whole mandibular arcade. The filly could not close her mouth with her lips. Radiographs showed radioopaque mass under the mandible. The mass was surgically excised from mandible. Histopathologically, gingival mass was characterized by hyperplastic gingival epithelium, well vascularized collagenous stroma and large area of bony tissues. Based on the gross and histopathologic findings, this case was diagnosed as ossifying epulis in the mandibular gingiva. This is the first report of ossifying epulis in a thoroughbred horse in Korea.

  • Fibrinopurulent peritonitis and abdominal abscesses associated with Streptococcus (S.) equi subsp. zooepidemicus is reported in a 1-year-old female thoroughbred horse. The horse died after showing 5-day history of the cold, severe abdominal distention, abdominal breathing, hyperthermia, anorexia, and loss of intestinal sound. At necropsy, several liters of turbid yellowish green fluid were seen in the abdominal cavity. Yellowish creamy and fibrinous or bloody materials were presented on the serosa of various abdominal organs that were intensively adhered with each other. Spleen and mesenteric lymph node were remarkably enlarged. Affected lobes of the lung showed severe congestion, hemorrhage and doughy consistency. Histologically, the lung showed hemorrhagic pneumonia with diffuse congestion and edema. Severe diffuse fibrinopurulent peritonitis with Gram-positive bacterial cocci and adjacent fibrosis were showed in the serosa of various abdominal organs such as liver, spleen, stomach, and intestine. And multifocal abscess pouches were presented in the granulation tissue of abdominal viscera. S. equi subsp. zooepidemicus was isolated from the peritoneal swab, abdominal organs, and lung. Hematogenous dissemination of bacteria from hemorrhagic pneumonia is proposed as the route of infection in this case.

  • Embryo transfer (ET) could be a relevant tool for genetic improvement programs in horses similar to those already underway in other species and produce multiple foals from the same mare in one breeding season. However, there have been no reports describing equine embryo transfer performed in Korea. In the present study, we performed an equine embryo collection and transfer procedure for the first time. We examined the embryo collection and pregnancy, size of embryo during the incubation period after collection, and progesterone (P4) and estradiol-$17{\beta}$ (E2) concentrations in mare's serum at embryo collection and transfer. A total of 16 donors responded to estrus synchronization; estrus was induced in 12 donors and 4 recipients, and artificial insemination was successful in 10 donors and six blastocysts were collected from donors. Of these blastocysts, we monitored the size of blastocysts for 3 day during incubation and transferred 2 blastocysts to a recipient, with 1 successful pregnancy and foal achieved. The dimensions of equine embryo at day 7 to day 9 were $409{\mu}m$, $814{\mu}m$ and $1,200{\mu}m$. The serum P4 and E2 concentrations were $7.91{\pm}0.37ng/{\mu}L$ and $45.45{\pm}12.65ng/{\mu}L$ in the donor mare, and 1$6.06{\pm}3.27ng/{\mu}L$ and $49.13{\pm}10.09ng/{\mu}L$ in the recipient mare.

  • The Dromedary camel (Camelus dromedaries) is an important species because of its ability to produce good quality meat, milk, and fibers under harsh environmental conditions. Camels are also crucial for transportation, racing, and as draft animals in agriculture. Therefore, dromedary camels play a critical role in the economy for millions of people living in the arid part of the world. The inherent capability of camels to produce meat and milk is highly correlated with their reproductive performance. Compared with other domestic species, the reproductive efficiency in camelids is low. Although recent reproductive technologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) have been successfully applied to camelids and the birth of live offspring following these technologies has been reported; in vitro embryo production (IVP) has lagged in this species. The development of the IVP system for dromedary camels may be a useful tool for the genetic improvement of this species. IVP in farm animals includes three main steps; in vitro maturation (IVM) of an oocyte, IVF of a matured oocyte, and in vitro culture (IVC) of fertilized oocyte up to the blastocyst stage. This review aims to summarize various factors that influence oocyte quality, IVM, and in vitro embryo development in dromedary camel.
