The tarsus in dogs has a complex structure that makes its evaluation relatively challenging. Because an accurate diagnosis of the tarsus is difficult through basic examinations alone, imaging tests are essential. Previous studies have explored the anatomical and radiological features of the canine tarsus using several imaging modalities. However, the imaging utility of the tarsus across different modalities has not been thoroughly evaluated. This study aimed to visualize the tarsal structures using magnetic resonance imaging (MRI) and ultrasonography, compare their utility, and propose suitable imaging modalities and conditions for evaluating specific tarsal structures. Magnetic resonance imaging and ultrasound scans of the tarsus of four healthy dogs were performed, and two observers rated the utility of each image on a five-point scale. Although MRI is more beneficial for assessing the tarsal structures than ultrasound, ultrasound also appears clinically useful for evaluating the cranial tibialis muscle, deep digital flexor tendon, subcutaneous fat, joint space, and superficial digital flexor tendon. In addition, each structure of interest can be evaluated for optimal visibility using specific ultrasound sections, MRI sequences, and planes. In veterinary clinical practice, an initial assessment using ultrasound imaging with optimal visibility is required and if further evaluation is necessary, MRI examinations with optimal MRI sequences and planes can be performed.

The levator and $M{\ddot{u}}ller^{\prime}s$ muscle balanced tucking was performed to correction myogenic or aponeurotic blepharoptosis. Through the blepharoplasty incision, the upper half of tarsal plate was exposed and the orbital was opened to show the levator aponeurosis. the $M{\ddot{u}}ller^{\prime}s$ muscle dissected from the upper border of the tarsal plate and from the posteriorly located conjunctiva with sharp scissors. $M{\ddot{u}}ller^{\prime}s$ muscle was advanced about 3 mm to 8 mm on anterior surface of the tarsal plate and fixed approximately upper one third of the tarsal plate with three horizontal 6-0 Nylon mattress sutures. The amount of tucking of $M{\ddot{u}}ller^{\prime}s$ muscle was controlled by the location of the upper eyelid margin 2 mm below the upper limbus in primary gaze after first temporary fixations suture in the maximum superior point of the limbus. The amount of advancement of levator aponeurosis was controlled by the location of the upper eyelid margin 1 mm below the upper limbus in primary gaze after first temporary fixations suture in the maximum superior point of the limbus. And then levator aponeurosis was fixed with three horizontal 6-0 Nylon mattress on beside the point that was tucked $M{\ddot{u}}ller^{\prime}s$ muscle. We have been thirty cases with levator and $M{\ddot{u}}ller^{\prime}s$ muscle balanced tucking from January 2004 to Jun 2005. 3 cases were traumatic blepharoptosis with 3-5 mm ptosis and poor levator function. 27 cases were myogenic or aponeurotic blepharoptosis with 2-5 mm ptosis with and more than 4 mm of levator function. the age of the patients ranged from 6 to 78 years. The levator aponeurosis and $M{\ddot{u}}ller^{\prime}s$ muscle tucking procedure can reduce the amount of the levator and $M{\ddot{u}}ller^{\prime}s$ muscle resection, and improve discomfort when the patients open eyes.

This study was to analyze properties of the foot form through a development figure of the surface area by factor analysis, cluster analysis, and reglation analysis. This study was performed 71 college women between 19 adn 23 years old residing in Pusan urban area. The result was as follows; 1. There are four factors selected by factor analysis. The 1st factor signifies the surface area of the toe. The 2nd factor signifies the surface area between Metatarsal circumfer-ence and Tarsal circumference. The 3rd factor signifies the surface area between Toe circumference and Metatarsal circumference. The 4th factor signifies the surface area between Heel-ankle circumference. 2. There are three clusters selected by fast cluster. Cluster 1 : The foot size, most parts of foot surface area and total foot surface area are relatively small to other clusters, but the surface area between Metatarsal circumference and Tarsal circumference is relatively large to other clusters. Cluster 2 : The foot size, all parts of foot surface area and total foot surface area are relatively large to other clusters as Cluster 1, but the surface area of the sole of the heel and the ankle is relatively large to other clusters. 3. Total surface area of the foot=-274.94+24.01* Foot lengh+9.28*Metatarsal circumference.

The cuticle of spider's exoskeleton is a hydrophobic and non-adhesive material, but the jumping spiders have the distinctive attachment apparatus for adhesion on smooth dry surface without sticky fluids. We have examined the whole tarsal appendages of the jumping spider, Plexippus setipes with using scanning electron microscope to reveal the fine structural characteristics of the dry adhesion system. All eight legs have the scopulae with a pair of claws on the tip of feet. Each scopula is composed of two groups of setae that are capable of dry adhesion on smooth surface, and the hook structure of the claw is advanced to move on the rough surface. The setae toward the bottom of the tarsal segment are densely covered by numerous setules on the underside which broadened from middle to distal portion. It has been revealed by this research that the contact area of the setule is always a triangular shape, and these cuticular surfaces are connected by the elongated stalks from the underlying setae. It is likely that the nano-scale structures including a triangular depression and a longitudinal groove on each setule could functionate when the spider detach its feet from the substrate.

The abnormal female fowl (Arbor Acres broiler) of 40-day-old, which was polymelia with polydactyly was observed macroscopically and radiographically. An extra pelvic limb was attached at the left pelvic region. The extra pelvic limb consisted of an underdeveloped and malformed Os coxae like bone, femur like bone, tibia and fibula like bones, tarsal and metatarsal like bones, and five digits. The tarsal bones of two normal pelvic limbs and one extra pelvic limb were not fused with tibia and metatarsal bones respectively. The metatarsus of extra pelvic limb consisted of a single bone derived from several components. In a case of normal, first metatarsal bone remains independent. However in this case. all of metatarsal bones were fused. The extra pelvic limb was polydactyly. The digits consisted of the first and extra digit of three. the second and third of four. and the fourth of five phalanges. In each toe the last phalanx was pointed and formed the claw. The first and the second digits were polyphalangia [hyperphalangia]. The extra digit was microdactylia and brachydactyly.

Talocalcaneal coalition known as the most common tarsal coalition is a congenital failure of segmentation. Talocalcaneal coalition with complete bone bridge is very rare, and there are few references in the literature about the clinical results and the operative method for this type of tarsal coalition. We report a case of 15 years old female with complete talocalcaneal coalition, who showed good clinical results by lateral sliding calcaneal osteotomy.

Background: Carpal tunnel syndrome (CTS) and tarsal tunnel syndrome (TTS) are thought to share a similar pathophysiology, compression of the median and plantar nerve by the carpal tunnel and flexor retinaculum. A few reports introduced the relationship between idiopathic CTS and TTS without definite evidence of coexistence. The current study was designed to analyze the electrophysiologic characteristics of combined idiopathic CTS and TTS by comparing with each idiopathic CTS or TTS. Methods: We retrospectively collected patients with combined idiopathic CTS and TTS (CTS-TTS group) from June 2001 to February 2009. Patients with each idiopathic CTS or TTS were collected as controls. Electrophysiologic data of median and plantar nerves were compared between CTS-TTS group and controls. Results: CTS-TTS group was composed of 31 patients. Control group of each CTS or TTS were 50 CTS and 49 TTS patients. In comparison of median nerve conduction study between CTS-TTS group and CTS control group, decreased compound muscle action potential amplitude (p<0.001), decreased median sensory nerve action potential amplitude (p<0.001) and sensory nerve conduction velocity at finger stimulation (p=0.013) were prominent in CTS-TTS group. Decreased medial plantar sensory nerve action potential amplitude (p=0.034) was indicated when CTS-TTS groups and TTS control group were compared. Conclusions: If the electrophysiology study of patients with CTS or TTS was suggestive of severe degree of nerve injury, concerns about the possibility of combined CTS and TTS would be helpful.

Drosophila 의 수컷 앞다리 부절에 존재하는 성즐의 유무는 Sophophora subgens와 Drsophila sub-genus의 분류기준이 되며, 전자의 경우는 종 특이적인 성즐을 가지나 후자에는 일반적으로 존재하지 않는다. 수종 Drosophila 의 성즐에 관하여 비교 조사한 결과 Sophophora subgens내의 D. melanoga-ster subgroup의 경우는 모두 제 1부절에만 존재하였다. 그중 D. melanogaster complex의 D. mauti-tiana 가 약 12.75개, D. simulans는 평균 8.35정도였으며, D. yakuba complex는 D. melanogaster complex에 비하여 다소 적었다. D. melanogaster complex의 종간 교배에 의한 분석으로는 성즐유전양시겡 대한 뚜렷한 방향성을 제시할 수 없었다. Sophophora subgemus의 D. melanogaster species group에 속하는 다른 3종의 경우(D. auralia, D. lutecens 및 D. suzuki)는 성즐의 분포 양식에서 D. immigrans 및 D. virilis)에서는 성즐이 존재하지 않았다.
