Four leptocephali (TL 109.8~129.7 mm) of the family Ophichthidae, collected from Sangju in the South Sea of Korea, were identified using morphological and molecular methods. Our four leptocephali were similar to Ophichthus sp. based on morphological characters: the melanophores present in series of eight gut swellings; total myomeres 144~151; body depth in total length less than 10%; eight or nine black horizontal bands present from anus to caudal fin base. On the other hand, our four leptocephali were identified to Pisodonophis sp. based on 826 base pairs of 12S rRNA gene nucleotide sequences. Our results showed that morphology-based identification did not agree with molecular identification, indicating difficulty in differentiating morphologically between Ophichthus and Pisodonophis leptocephali. We, herein, firstly describe morphological characteristics of Pisodonophis sp. leptocephali from Korea.

Experimental infection method for Edwardsiellosis was studied to imitate histopathologically natural infections in the Tilapia Oreochrimis niloticus. Prior to the bacterial challenge, the intestine of tilapia was damaged by 0.2ml of 30% hydrogen peroxide introduced through a silicon tube which was inserted 4 to 5cm into the intestine from anus. E. tarda was mixed a 10% Gum arabia and administered into the stomach by a cannula 20 hours after the hydrogen peroxide treatment. Bacterial doses used were from $4.2{\times}10^6$ to $6.4{\times}10^\;CFU$/fish. Fish 72 hours after the challenged showed swollen and erosious lesion and focal necrosis with bacterial-eaden inflammatory cell in the Liver, Spleen, Kidney. Fish 96 and 120 hours after bacterial challenge were moribund showing swollen Liver, Spleen, Kidney and focal accumulation of macrophages and production of granulomas in the infected lesions.

Objectives : This study anus to investigate the effects of Rosa Rugosae Radix (RU) herbal acupuncture on the metabolic syndrome in high-fat diet-fed mice. Methods : The experimental groups were fed with high-fat diet (HFD) for 8 weeks to induce metabolic syndrome. During the induction of metabolic syndrome, RU herbal acupuncture at a dosage of 50 mg/kg was carried out on the point of Sinsu(BL23) every day to measure the body weight, feed efficiency, blood glucose levels, insulin resistance index, lipid levels, blood pressure, and weight of liver and adipose tissues (brown adipose tissue from interscapular fat and white adipose tissue from epididymal fat). And after five weeks' induction of metabolic syndrome, RU herbal acupuncture was also performed for 6 weeks to measure the body weight and blood glucose levels. Results: 1. RU herbal acupuncture inhibited increasing body weight and blood glucose levels, with improved insulin resistance. 2. RU herbal acupuncture inhibited increasing levels of total cholesterol, LDL-cholesterol and free fatty acid, while increased HDL-cholesterol levels. 3. RU herbal acupuncture activated anti-hypertensive action. 4. RU herbal acupuncture inhibited increasing weight of white adipose tissues, but not in brown adipose tissues and liver. 5. RU herbal acupuncture lowered blood glucose levels and inhibited increasing body weight in metabolic syndrome-induced ICR mice. Conclusion : Rosa Rugosae Radix (RU) herbal acupuncture showed effectiveeness in prevention and management of metabolic syndrome in clinical application.

The seven leptocephali (14.6~68.0 mm in total length) of the family Ophichthidae, from the East Sea of Korea, were identified using 12S rRNA 861-bp sequences and their morphological development were described. Our seven leptocephali were identified to Echelus uropterus based on genetic distance (d=0.000) being well consistent with that of adult E. uropterus. Our seven leptocephali of E. uropterus are characterized by morphological combinations: caudal fin present; the melanophores present in series of nine gut swellings; total myomeres 154~158; body depth in total length less than 10%; eight black horizontal bands present from anus to caudal fin base. Our morphological and molecular results suggest that E. uropterus may be an intermediate group between subfamily Ophichthinae and Myrophinae.

This study is a retrospective analysis of 1244 cases of the inguinal hernia in children under the age of fifteen years who were operated at the department of pediatric surgery, Inje University Busan Paik Hospital from March, 1997 to February, 2007. The ratio of male to female was 3.6:1. The type of hernia was indirect in all of the cases. The hernia was on the right side in 656 cases (53.9 %), left side in 467 cases (37.5 %), and bilateral in 121 cases (9.7 %). The hernia presented most frequently in infants under age 12 months; 364 cases (29.2 %). Fifty-nine cases (21.7 %) were in female and 305 cases (31.3 %) in male. There were 428 cases (33.6 %) in 1-3 years age group, 295 cases (23.7 %) in 4-6 years, 112 cases (9.0 %) in 7-9 years, 39 cases (3.1 %) in 10-12 years and 16 (1.2 %) in 13-15 years. The content of hernia sac was small bowel (59 %), omentum (31 %) in males and the ovary and tube (54 %) and small bowel (26 %) in female. The incidence of combined operation at the time was 3.2 %, and consisting of orchiopexy (67.5 %), frenulotomy (12.5 %), appendectomy (10 %), circumcision (5 %), and fistulotomy (5%). The incidence of combined disease was 2.8 % and consisting of undescended testis, Hirschsprung's disease, idiopathic hypertrophic pyloric stenosis, imperforate anus, and congenital heart disease. After unilateral inguinal hernia repairs, contralateral hernias developed in 34 patients. The laterality of the primary site of hernias were left in 19 cases (55.8 %), and right 15 cases (44.1 %). The 936 cases (75.2 %) were operated under general anesthesia; Mask bagging 663 cases (53.2 %), endotrachea intubation 257 cases (20.6 %), and laryngeal mask 16 cases (1.2 %). The remainder 308 cases (24.7 %) were operated under regional caudal anesthesia.

Objectives: This study was to propose a standardized method of retention enema by extracting elements associated with published experimental methods of retention enema. Methods: 1) Literature search (1) Data sources: Retrieval was made, using 'Enema' or 'Retention Enema' as search words in Medline, Cochrane library, KISS, RISS, and KDSL DB. (2) Study selection: Two authors excluded irrelevant papers and chose qualified abstracts from the rest of the papers. The chosen studies were reviewed fully by the authors so that they could screen the significant papers based on the exclusion criteria. (3) Data extraction: Data on the total number of subjects, the target disease, the animal species, the type, quality, length, and diameter of catheter, the insertion length of catheter, the sample, the sample volume, the process of retention enema and the number of retention enemas performed were extracted from the selected studies. 2) Performing preliminary experiments about the elements associated with experimental methods of retention enema. Results & Conclusions: The standardized experimental method is as follows: animal: 280-320g SD rat 1) inserting a rectal tube of 8 Fr that measures 8 cm into the animal's anus, 2) injecting herbal medicines at the volume of 6ml and 3) holding them for 10 minutes.

McKusick-Kaufman syndrome (MKS) is an autosomal recessive multiple malformation syndrome characterized by hydrometrocolpos (HMC) and postaxial polydactyly (PAP). We report a case of a female child with MKS who was transferred to the neonatal intensive care unit of Seoul National University Children's Hospital on her 15th day of life for further evaluation and management of an abdominal cystic mass. She underwent abdominal sonography, magnetic resonance imaging, genitography and cystoscopy which confirmed HMC with a transverse vaginal septum. X-rays of the hand and foot showed bony fusion of the left third and fourth metacarpal bones, right fourth dysplastic metacarpal bone and phalanx, right PAP and hypoplastic left foot with left fourth and fifth dysplastic metatarsal bones. In addition, she had soft palate cleft, mild hydronephroses of both kidneys, hypoplastic right kidney with ectopic location and mild rotation, uterine didelphys with transverse vaginal septum and low-type imperforated anus. She was temporarily treated with ultrasound-guided transurethral aspiration of the HMC. Our patient with HMC and PAP was diagnosed with MKS because she has two typical abnormality of MKS and she has no definite complications of retinal disease, learning disability, obesity and renal failure that develop in Bardet-Biedl syndrome, but not in MKS until 33 months of age. Here, we describe a case of a Korean patient with MKS.

Objectives : The purpose of the present study is to evaluate the effects of herbal acupuncture with Ginseng Radix for the treatment to intestinal disease in the rat with 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced colitis. Methods : All animals were subjected to the injection of saline $(300{\mu}{\ell},\;500{\mu}{\ell})$ for a study control or TNBS $(300{\mu}{\ell},\;500{\mu}{\ell})$ into the lumen of the colon, 8cm proximal to the anus through the intestine. Ginseng Radix herbal acupuncture ($20mg/m{\ell},\;0.4m{\ell}$) were injected to the both $Hapgok(LI_4)$ acupoints at 2nd injection of TNBS in rats. Thus, the body weight, RBC count, WBC count, total protein, IgG levels and IgM levels were observed to study the effects of Ginseng Radix herbal acupuncture. Results : Ginseng Radix herbal acupuncture on $Hapgok(LI_4)$ for TNBS-induced colitis inhibited the body weight loss rate but did not affect RBC and WBC counts. Furthermore, it inhibited the reduction of total protein concentration and serum IgG and IgM levels in TNBS induced colitis were recovered. Conclusions : Herbal acupuncture with Ginseng Radix helps recover the TNBS-induced colonic damage and may be an important method for treatment of the colitis.

In order to monitor the developmental features of embryos, larvae, and juveniles of Oryzias latipes (Temminck and Schlegel), Oryzias latipes was caught in river of Shinduck-dong, Yeosu-si, Jeollanam-do, on May 2011, and experiments were carried out in Ichthyology laboratory at Chonnam National University. The blastodisc step was the first level for natural spawning. The optic vesicle, Kupffer's vesicle, myotome began to appear 75 hours 57 minutes later. After blastodisc development, the pectoral fins were made at 143 hours 37 minutes and the tail was separated started at the same time. Hatching was observed at 167 hours 27 minutes after blastodisc. The total length of the hatched larvae was 4.95~5.10 mm (mean, 5.01 mm), the mouth and anus were opened. Larvae used yolk completely after 3 days after hatching. The total length larvae was 5.45~5.56 mm (mean, 5.52 mm) after 8 days after hatching, and appeared the stems for tail. The stems pectoral, anal fin were showed after 14 days and the stems dorsal, ventral fin were appeared after 19 days. For 35 days after hatching, the total length of larvae 13.95~15.30 mm (mean, 14.64 mm), and at this time, fins and body were transferred like the adult Oryzias latipes.
