Two specimens of Chlorophthalmus nigromarginatus Kamohara, 1953 (51.02 mm, 66.04 mm in standard length) belonging to the family Chlorophthalmidae were collected on February 8, 2022 in the eastern Jeju-do Island, Korea using a bottom trawl. The species has the following morphological characteristics: snout length almost the same as orbit diameter, bump absent on predorsal, caudal fin with posterior black margin. C. nigromarginatus is morphologically very similar to C. acutifrons but can be distinguished by caudal fin with black margin (C. acutifrons has no black margin). Molecular analyses showed that our specimens almost matched with C. nigromarginatus according to mtDNA 16S rRNA sequences (99.8%). Therefore, we propose a new Korean name for C. nigromarginatus, "Geom-eun-kko-ri-pa-rang-nun-mae-tung-i".

A single specimen (91.5 cm standard length) of the salmonid species, Oncorhynchus tshawytscha (Walbaum, 1792) was collected on April 19, 2022 in Sokcho-si, Gangwon-do, Korea. O. tshawytscha has the following morphological characteristics: base of lower jaw teeth is black, black spots are scattered on the dorsal section of body, and the edge of caudal fin is black. Although the species is morphologically similar to Oncorhynchus kisutch, O. tshawytscha differs from it in having black spots on the caudal fin. Molecular analysis results based on mitochondrial cytochrome c oxidase subunit I (COI) sequences showed that our specimen perfectly matched with the COI sequences of O. tshawytscha registered at the NCBI. Therefore, we suggest the new Korean name 'Wang-yeon-eo' for O. tshawytscha.

Background: Epidural blocks are widely used for the management of acute and chronic pain. The technique of loss of resistance is frequently adopted to determine the epidural space. A discontinuity of the ligamentum flavum may increase the risk of failure to identify the epidural space. The purpose of this study was to investigate the anatomic variations of the cervical and high thoracic ligamentum flavum in embalmed cadavers. Methods: Vertebral column specimens of 15 human cadavers were obtained. After vertebral arches were detached from pedicles, the dural sac and epidural connective tissue were removed. The ligamentum flavum from C3 to T6 was directly examined anteriorly. Results: The incidence of midline gaps in the ligamentum flavum was 87%-100% between C3 and T2. The incidence decreased below this level and was the lowest at T4-T5 (8%). Among the levels with a gap, the location of a gap in the caudal third of the ligamentum flavum was more frequent than in the middle or cephalic portion of the ligamentum flavum. Conclusions: The cervical and high thoracic ligamentum flavum frequently has midline intervals with various features, especially in the caudal portion of the intervertebral space. Therefore, the ligamentum flavum is not always reliable as a perceptible barrier to identify the epidural space at these vertebral levels. Additionally, it may be more useful to insert the needle into the cephalic portion of the intervertebral space than in the caudal portion.

분류학적으로 참복과에 속하는 흰점꺼끌복, Arothron hispidus (Linnaeus, 1785)은 2003년 7월에 전라남도 고흥군 녹동연안에서 저층 트롤로 3마리(체장 62.7~71.0 mm)를 채집하였다. 체색은 전체적으로 검회색이지만 색의 변화가 다양하며, 측면 관찰 시 가슴지느러미를 기준으로 위쪽에 하얀 반점이 분포하며, 가슴지느러미 아래쪽으로 반원의 흰색 띠가 배를 덮고 있는 특징을 가지고 있었다. 등지느러미 줄기수는 11~12개이며, 뒷지느러미 줄기수는 10~11개, 가슴지느러미 줄기수는 17개, 꼬리지느러미 줄기수는 5+6=11개였다. 두개골은 총 13개의 골편으로 구성되어 있었고, 같은 속 꺼끌복에 비하여 사골 길이, 액골의 크기에 차이를 보였다. 악골은 위턱에 전상악골과 주상악골, 아래턱에 치골, 관절골 및 각골로 구성되어 있고, 꺼끌복에 비해 각골과 관절골의 크기는 크게 나타났다. 현수골은 구개부가 7개, 새개부는 4개의 골편으로 이루어져 있고, 견대부의 상쇄골과 쇄골은 T-자형으로 연결되어 있다. 척추골은 크게 복추골과 미추골로 나누며, 그 수는 8+10=18개였고, 등지느러미를 지지하는 담기골식은 $7{\ast}1231$으로 꺼끌복의 7*1232와 차이를 보였다.

긴몰개 Squalidus gracilis majimae 백색증 개체가 자연에서 발견되어 조직학적 분석을 통해 정상개체와의 차이를 비교하였다. 백색증 개체는 정상 개체에 비해 체색의 발현이 이루어지지 않았다. 등, 체측, 배, 미병부 상부, 미병부 하부, 등 뒷지느러미 및 안구조직에 대한 조직형태에서는 정상과 백색증 개체간 차이가 없었으나 멜라닌 색소의 분포 및 발현량에서 차이를 보였다. 정상 개체의 경우, 멜라닌 색소는 배쪽을 제외한 모든 부위에서 잘 발달한 모습을 볼 수 있었다. 그러나 백색증 개체의 경우, 멜라닌 색소는 눈과 몸통의 위쪽부위에서 매우 희미하게 관찰되었고, 아래쪽 부위(배, 미병부 하부, 뒷지느러미)에서는 전혀 발견되지 않았다. 이러한 멜라닌 색소의 분포는 빛과 연관이 있을 것으로 추측되었다.

The ovaries of Korean native cows or heifers were obtained from a slaughter house and kept on 28~3O˚C and transported to laboratory within 2 hrs. The follicular oocytes were collected follicles. The oocytes were matured in vitro for 24 hrs. In TCM-199 supplemented with 35 $\pi$g /ml FSH, 10 $\pi$g /ml LH, 1 $\pi$g /ml estradiol-17 and granulosa cells at 39˚C under 5% $CO_2$ in air. The caudal epididymis of Korean native bulls were obtained from a slaughter house and transported to laboratory within 30 minutes. Swim-up of collected spermatozoa and freezing sperm was layered under 2ml fertilization B. 0. medium in two tissue culture tubes and held at a 45˚C angle for 0~2 hrs. They wrer fertilized in vitro by freezing sperm treated with heparin for 24 hrs, and then the zygotes were co-cultured in vitro with bovine oviductal epithelial cells for 7 to 9 days. The follicular oocytes recovered were classified into 41.7% as grade I, 51.5% as grade II and 6.8% as graed III. The number of oocytes recovered per ovary was averaged 8.3 and they were classifed into 2.3 as grade I, 2.5 as grade II and 2.3 as grade III. The cleavage rate of matured oocytes was significantly(P

Background: Sacral nerve stimulation is a therapeutic option with demonstrated efficacy for conditions presenting with perineal pain caused by different etiologies. We aimed to assess whether a sacral electrode ($Interstim^{(R)}$, Medtronic, Minneapolis, MN, USA) inserted through the caudal pathway is able to offer an acceptable level of sacral stimulation and rate of catheter migration. Methods: We present 12 patients with pelvic pain who received sacral neuromodulation via the sacral hiatus with the InterStim electrode. We evaluated patient satisfaction as well as migration and removal of the electrode, if necessary. Results: Our experience included 12 patients, 10 women and two men, with a mean age of 60 years. In eight of the 12 patients, the initial therapy was effective, and the final system implantation was performed. During subsequent follow-up, patient satisfaction was good. To date, there have been no cases of electrode displacement or migration. Conclusions: The caudal insertion of the InterStim electrode, with its own fixation system, and initially designed for transsacral insertion, appears in our experience to be a satisfactory option which can minimize electrode displacements, achieving similar results in therapeutic efficacy and causing no difficulties in removal.

The fused thoracic vertebra and deformity of the lumbar vertebrae in the female Thoroughbred horse were observed macroscopically. The 11th and 12th thoracic vertebrae (T) were partially fused. They were composed of three parts between the spinous process of the 11th and 12th T, left and right caudal articular processes of the 11th T, and left and right cranial articular processes of the 12th T. The vertical surface of cranial articular process of the 11th T and left mamillary process of the 12th T were absent. The left caudal part of the transverse process of the 12th T and left costal fovea of the transverse process of the 12th T were severely deformed. On the other hand, the left transverse process of the first lumbar vertebra (L) was a typical rib-like transverse process and two times longer than the right transverse process of the 2nd L. The right transverse process of 4th L has an oval concave facet on the medial part of caudal border for articulation with the right transverse process of 5th L; the latter has a corresponding convex facet on the medial part of the cranial border in the right transverse process of the 5th L.
