The urinary bladder retroflexion, flipped over backwards into the pelvic canal, by trauma has been rarely reported in dogs. This paper describes clinical and radiological features of urinary bladder retroflexion in two dogs with a history of traffic accident. The main clinical signs were hind limb lameness, severe pain and dysuria. Radiography and ultrasonography were performed to evaluate the patient's damages. No remarkable findings were observed except pelvic fracture on survey radiograph. On cystourethrography, caudal displacement and retroflexion of the bladders were identified. Cystopexy was performed and the bladders were repositioned. After surgery one dog with severe azotemia and bilateral hydroureteronephrosis was deteriorated noticeably and euthanized by request of the owner, while the other dog was recovered no recurrence of the problem by 12 months post-surgery. It should be considered that contrast study and serial assessment in urinary tract be important to demonstrate the evidence of bladder retroflexion and evaluate the prognosis in dogs with severe trauma.

A 7-year-old intact male Maltese dog was presented with firm, raised, erythematous, alopecic, and pruritic skin lesions on the right dorsal distal metatarsal region and the tail. The skin lesion started a year ago with a crust-like lesion on the right dorsal distal metatarsal region which gradually swelled as the patient continued to lick and chew without healing. Recently, similar lesions occurred on the tail. Based on the licking history and ruling out other diseases through skin examination, acral lick dermatitis (ALD) was diagnosed. Treatment included antidepressants, preventive antibiotics, topical corticosteroid, and wearing Elizabethan collar as a physical barrier. After three weeks, the lesion on the hind limb healed entirely. However, the tail lesion recurred as it was able to lick the tail again with a type of an E-collar. This case shows that it is essential to block the contact lesion and provide medical treatment until the lesion has been completely resolved for successful management of ALD.

This study was conducted to find the sexual size dimorphism(SSD) in morphometric characters of three species, Eremias argus, Takydromus amurensis and T. wolteri in lacertid lizard from Korea. Six external traits, snout-vent length, tail length, head length, head width, forelimb length and hind-limb length were focused to compare two sexes among the each three lizards. Student's t-test was used to compare the adult SVL between the sexes for each species. For the other parts of the body, a one-way analysis of covariance(ANCOVA) with SVL as the covariate was used. In all these species, males have longer tail and head than females like general lacertid lizard. In addition, male E. arugus have broader head and longer forelimbs and hind-limbs than conspecific females. Likewise, male T. wolteri have broader head than females. In the three lacertid lizards from Korea, snout-vent length did not significantly differ between the sexes. To understand the causes for SSD in SVL, ecological information, such as the presence/absence of male-male combat and the correlation between the SVL of female and litter size, is required. Therefore, further ecological study on the three species of lacertid lizard from Korea will make it possible to explain the reason SSD is not found in SVL.

Two weeks of therapy with intra-articular hyaluronic acid and oral caprofen failed to improve the clinical signs of hip osteoarthritis radiologically confirmed in a dog. Then, over the period of 30 days (7 sessions at 5-day intervals), bee- venom acupuncture (BV-AP, injection of bee venom at acupoints, also called apitoxin-aquapuncture) plus Trigger Point (TP) therapy was used. Five acupoints on the affected right limb were injected each time: GB30(as local point), plus ST35, GB33, BL40 and LIV08 (as distant points). The injection mixture (0.2 ml/point; total 1 ml/session) was saline + apitoxin + 2% lidocaine, so that the injected solution contained $100{\mu}g$ apitoxin diluted in 0.2% lidocaine-saline solution/ml. The total dose of apitoxin used was, therefore, $100{\mu}g/session$, divided over the 5 acupoints. One TP in the middle of the right quadriceps muscle was injected with 2% lidocaine (0.2 ml/point) each time. BV-AP improved the clinical signs rapidly; lameness and ataxia were disappear after 7 sessions (30 days); the right hind limb muscular atrophy was much improved and the hip radiograph was almost normal two weeks after 7 sessions (44 days). The present patient was a case with canine hip osteoarthritis which showed favorable therapeutic response by BV-AP plus TP therapy.

Ischemic stroke results from a transient or permanent reduction in cerebral blood flow that is restricted to the territory of a major brain artery. Thus, this study was performed to examine (1) the effects of swimming exercise on the improvement of muscle atrophy, and (2) exercise and HSP 70 expression in an ischemic stroke model induced by middle cerebral artery occlusion. The results of this study were as follows: One week after ischemic stroke was induced, changes appeared in the muscle weight of the gastrocnemius muscle due to muscle atrophy in the affected side. Group II showed statistically significant difference from group III eight weeks after ischemic stroke was induced. (p<.05). One week and eight weeks after ischemic stroke was induced there was significant decrease in the relative muscle weight of the gastrocnemius muscle in each group except Group IV, while there was statistically significant increase in group II eight weeks after ischemic stroke was induced, compared to group III (p<.05). For neurologic exercise behavior tests, Group II generally had the highest score, compared to other groups. In immunohistochemical observations, Group II showed a decrease in HSP 70. The above results suggest that swimming exercise improved muscle atrophy, changed the HSP 70 expression of ischemic stroke in rats, and contributed to the improvement of exercise function.

Objective: The expression of CRF(corticotropin releasing factor), CRF-R(receptor) and CRF-BP(binding protein) in CNS neurons projecting to the stomach and ST36 using the pseudorabies virus in the rat was investigated. Methods: After survival times of 5 days following injection of PRV-Ba-Gal, The thirty rats were perfused, and their brain were frozen sectioned($30{\mu}m$). These sections were stained by PRV-Ba-Gal histochemical staining method and(or) CRF, CRF-R and CRF-BP immunohistochemical method. The common expressed areas of the brain projecting to the stomach and zusanli(ST36) following injection of PRV-Ba-Gal were observed with light microscope. Results: 1) The dense accumulation of CRF-immunoreactive terminals is seen in the area postrema, n. tractus solitarius, external zone of the median eminence, with some immunoreactive CRF also present in the internal zone. 2) Aggregates of CRF-R immunoreactive perikarya are found in area postrema, n. tractus solitarius, lateral reticular n., gigantocellular reticular n., locus coeruleues, paraventricular n. of hypothalamus, median eminence, preoptic n., arcuate n. and hind limb area of cerebral cortex. 3) Aggregates of CRF-BP immunoreactive perikarya are found in area postrema, n. tractus solitarius, lateral reticular nucleus, gigantocellular reticular n., locus coeruleues, paraventricular n. of hypothalamus, median eminence and arcuate n.. Conclusions : These results suggest that PRV-Ba-Gal labeled areas projecting to stomach and ST36 may be related to the central autonomic pathways. A part of CNS neurons projecting to the stomach and ST36 were related to expression of CRF, CRF-R and CRF-BP related to the stress in central autonomic center.

The purpose of this study was to examine the effect of neuromuscular electrical stimulation(LFES) during hindlimb suspension on weight and function of rat hindlimb muscles. Sprague-Dawley rats(body weight 300-350g) were randomly assigned to five groups: a HLS(n=5) that were hindlimb suspended for 14 days, a WB(n=5) that kept as control, a ES14 that were hind limb suspended for 14days with pre-application of LFES for 14 days, ES11 that were hindlimb suspended for 14 days with pre-application of LFES for 11 days, a LFES 7 that were hindlimb suspended for 14 days with pre-application of LFES for 7 days. Gastrocnemius muscle weight, stride length were significantly decreased and toe out angle were significantly increased in HLS and ES7 groups, whereas muscle weight, stride length, toe out angle were maintained in ES14, ES11. this indicated that LFES for 14 days, LFES for 11 days could prevent muscle atrophy and retain function.

Advances in immunosuppressive treatments and microsurgical techniques have rendered composite tissues allotransplantation (CTA), such as heteregeneous or non-organ tissues, possible in humans. CTA has evolved dramatically since the first successful rat hind limb allotransplantation. Numerous clinical applications including face, hand, trachea, larynx, and vascularized joint have been performed. Although composite tissue allografts are still in their infancy, they have opened a new era in the field of transplantation surgery and pathology, so that maxillofacial reconstructive surgeons may occasionally be faced with the challenge of diagnosing skin refection of a composite tissue allograft. Facial allotransplantation (FAT) is a new surgical technique that could be considered as a new paradigm in facial reconstruction. Since the first human FAT had been achieved in 2005, 17 cases have been reported in the world up to date. However, many problems such as life-long immunosuppression, immune rejection, ethical problems and psychological problems are remained, so facial CTA is new reconstructive option with no general acceptance. The authors reviewed the indications, the results of 17 cases and their complications, and additional consideration factors in this article, and intended to raise the awareness of oral and maxillofacial surgeons in this type of facial transplantation.

This study was performed to investigate the effect of different levels of protein and iron in the diet upon Fe, Cu and Zn metabolism in rat during four weeks of growing period. Forty-five male weanling rats of Sprague-Dawley strain weighing $68.5{\pm}1.1g$ were divided into 9 groups and each group was given with one of the 9 different kinds of diets for four weeks. The three dietary protein levels used were 5, 20 and 40% and Fe levels 0, 35, and 350 ppms. The results obtained were summarized as following ; 1) Food intake and body weight gain in 20%(SP) and 40%(HP) dietary protein groups tended to be significantly higher than 5%(LP) protein groups. Protein efficiency ratio (PER) was higher in LP groups than in HP and SP groups. With dietary Fe levels, there were no significant differences among groups in food intake, body weight gain, and PER. 2) In LP groups, the Fe concentrations in liver, kidney, and hind limb muscle were higher than in SP and HP groups. Regarding with dietary protein levels, the liver Cu concentrations in LP groups were slightly higher, but the liver Zn concentrations were lower in LP groups. The Fe concentrations in liver and kidney tended to decrease with decrease in dietary Fe levels, but Cu and Zn concentrations showed no consistent tendency with dietary Fe levels. 3) The Fe, Cu and Zn concentrations in serum were not different from dietary treatments except that the serum Fe concentrations increased slightly in LP groups. 4) The Fe and Cu concentrations in urine tended to be higher in HP groups. Fecal Cu and Zn concentrations showed no significant differences in dietary protein or Fe levels, but the Fe concentrations tended to increase with increase in dietary Fe levels.

Purpose: This study is intended to examine the aquatic exercise on the improvement of muscle atrophy and motor function in an ischemic stroke model induced by middle cerebral artery occlusion. Methods: We used 60 Sprague-Dawely rats which were divided into 4 groups; the subjects were divided into group of 5 rats. Group I was a group of high dose aquatic exercise after inducing ischemic stroke; Group II was a group of low dose aquatic exercise after inducing ischemic stroke; Group III was a control group, Group IV was a sham group without ischemic stroke. Results: Muscle weight of gastrocnemius muscle was significantly difference in Group II compared to Group III on 8 weeks(p<0.05). For the changes in relative muscle weight of gastrocnemius muscle, there was significant increase in Group II compared to Group III on 8 weeks(p<0.05). For neurologic exercise behavior test, Group II generally had the highest score, compared to other groups. The results of behavior test that Group II improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, indicating a similar state of muscle fiber and brain to Group III. Conclusion: Based on these results, aquatic exercise may improve muscle atrophy and contribute to the improvement of motor function.
