Hormonal induction of sex reversal was examined by using sex steroid hormones in serranid fish, Epinephelus septemfasciatus. Young fish were collected from the coastal area of Cheju Island, and reared for 2 years before fish were used for the experiments. Without any hormonal treatment, gonads of fish ($1,000\~2,800$ g in body weight) were occupied by oocytes of the perinucleolus stage and bundles of protogonial cells in the area of germinal epithelium. When the induction of sex reversal was attempted by daily oral administration of $17\alpha$-methyltestosterone (0.5 mg/kg fish) for 90 days, active spermatogenesis was induced, and spermatogonia and spermatocytes and spermatids were appeared in all gonads we examined. However, after daily, oral treatment of $17\beta$-estradiol (0.5 mg/kg fish) to. 50 days with the following injection of human chorionic gonadotrophin ($1,000\~1,500$ IU/kg fish) mature oocytes were not induced in fish gonad.

Fungal arthritis is a rare joint infection that occurs in immunosuppressant patient, intravenous drug abuser and long term antibiotics user, and is especially rare in a healthy adult. Two case reports of fungal arthritis have been demonstrated in the country, but those in healthy adults have not been reported yet. Here, we experienced an antifungal treatment following successful arthroscopic debridement of fungal arthritis with a popliteal cyst in a healthy adult who got repetitive intraarticular steroid injections and report the case with review of relevant literatures. Surgeons should consider the possibility of fungal arthritis although it is rare and demonstrates nonspecific clinical features.

Caudal epiduroscopy has been introduced as an alternative technique for direct injection of epidural steroid and lysis of adhesion. Futher, it gives a better understanding of the role of epidural adhesion in recurrence of sciatica and low back disorder after surgery. We experienced a clinical application of flexible fiberoptic epiduroscope inserted through the sacral canal. A 37-year-old woman was suffering from right lumbar radiculopathy after an operation for a herniated disc. A series of volumetric caudal steroid injections and physical therapy had little effect on her symptoms. Patient was thought to be a good candidate for epiduroscopy. Flexible flberoptic epiduroscopy was as follows: 60 ml of normal saline irrigation and epidurogram, 40 mg of triamcinolone in 10m1 of normal saline was directed around right L5 nerve root. The following morning, patient reported reduced pain in her leg.

Chloroma is a localized myeloblastic tumor which may develop during the course of myelogenous leukemia or as a presenting sign of the disease. A 47-year-old female diagnosed as chronic myelogenous leukemia in her hematologic remission period complained of left lower leg pain. The lumbar-spine series showed multiple osteolytic changes in the left lateral border of the lumbar spine. An inhomogenous soft tissue mass involving left lateral aspects of lumbar vertebrae was identified by CT-scanning. At the first pain attack, lumbar epidural steroid and local anesthetic injection could abolish her pain and the patient could go a few days without pain. The following radiation therapy could also improve the symptom and retain the pain free interval. One month later, a second pain attack occurred and lumbar and caudal epidural steroid and local anesthetic injections could result only in an incidental relief of pain. Radiation and chemotherapy were started but failed to relieve pain. A neurolytic block was considered but the patient's general condition was aggravated and even verbal communication with her became impossible.

Objective : A case of idiopathic spasmodic torticollis rapidly improved after Oriental Medical treatments and supplementary trigger point injection is reported. Methods & Results : The oriental medical treatment for spasmodic torticollis including acupuncture, bee-venum therapy, herb medication, taping therapy, chuna therapy and physical therapy was performed for pain alleviation, and trigger point steroid injections were also performed. The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) and the Tsui Score were used for outcome measure of the spasmodic torticollis. After treatment for 15 days, the TWSTRS showed a decrease from 56 to 22.3 and the Tsui score also decreased from 13 to 5. Conclusions : We concluded that the oriental medical treatment including acupuncture, bee-venum therapy and taping therapy rapidly induced spasmodic torticollis to remission.

Background The clinical results of conservative treatment options for ulnar compression at the elbow have not been clearly determined. The aim of this review was to evaluate available conservative treatment options and their effectiveness for ulnar nerve compression at the elbow. Methods In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a systematic review and meta-analysis of studies was performed. Literature search was performed using Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). Results Of the 1,079 retrieved studies, 20 were eligible for analysis and included 687 cases of ulnar neuropathy at the elbow. Improvement of symptoms was reported in 54% of the cases receiving a steroid/lidocaine injection (95% confidence interval [CI], 41-67) and in 89% of the cases using a splint device (95% CI, 69-99). Conclusions Conservative management seems to be effective. Both lidocaine/steroid injections and splint devices gave a statistically significant improvement of symptoms and are suitable options for patients who refuse an operative procedure or need a bridge to their surgery. Splinting is preferred over injections, as it shows a higher rate of improvement.

Objective : This study aimed to evaluate the clinical feasibility of the combination of ultrasound and nerve stimulator guidance in transforaminal epidural steroid injections (TESIs) to manage lumbosacral chronic radicular pain. Methods : Using the combination of nerve stimulator and ultrasound guidance, TESIs were performed in 125 segments of 78 patients who presented with chronic lumbar radicular pain. Demographic characteristics and surgical outcomes were recorded on admission, pre-procedural and post-procedural for 1-week, 1-month, 3-month, and 6-month follow-ups. The result was measured using the Numeric rating scale (NRS) and Oswestry disability index (ODI). Results : Patients who received TESIs showed significant improvements on two evaluation tools (NRS, ODI), compared to that before procedure (p<0.001). No significant complications were observed for 6 months' follow-up. Conclusion : The result suggests that a combination of ultrasound and nerve stimulator guidance in transforaminal epidural injections is safe, reliable and effective for short-term management of lumbar disc herniation. It is a promising technique and has shown good results in providing intermediate pain relief.

Porokeratosis ptychotropica is an uncommon form of porokeratosis, which was initially described in 1995. It is clinically characterized by symmetrical reddish to brown-colored hyperkeratotic, verrucous, or psoriasiform plaques on the perianal and gluteal regions. The lesions tend to integrate and expand centrally, with small peripheral satellite lesions. Early skin biopsy and appropriate diagnosis are essential because malignant change occurs in 7.5% of porokeratotic lesions. Conventional treatment options include topical steroid, retinoid, imiquimod, 5-fluorouracil, isotretinoin, excimer laser, photodynamic therapy, intralesional steroid or bleomycin injection, cryotherapy, carbon dioxide (CO₂) laser, and dermatome and excision, but none seem to achieve complete clearance. A 68-year-old woman presented with diffuse hyperkeratotic scaly lichenoid plaques on the buttocks that had persisted for several years. A skin biopsy of the buttocks revealed multiple cornoid lamellae and intense hyperkeratosis. There were some dyskeratotic cells beneath the cornoid lamellae and the granular layer was absent. Porokeratosis ptychotropica was diagnosed based on the characteristic clinical appearance and typical histopathological manifestations. She was treated with a CO₂ laser in one session and topical application of urea and imiquimod cream for 1 month. The lesions slightly improved at the 1-month follow-up. We herein present a rare case of porokeratosis ptychotropica.

Steroid hormone is known to cause the dynamic changes of mammalian uterus during reproductive cycle. However there is little information about the effect of estrogen (E) and progesterone (P) on the expression of various transcription factors involved in gene expression. Thus the present study was designed to demonstrate E and/or P-induced expression of c-Fos, CREB, ATF and HSP70 in rat uterus. Rats, ovariectomized (OVX) for two weeks, were divided into 6 experimental groups, 1) OVX, 2) OVX+V, 3) OVX+E, 4) OVX+P, 5) OVX+E+V, 6) OVX+E+P, and western blotting assay for nuclear extract and immunohistochemical staining were carried out for each experimental group. Treatment of E $(10{\mu}g)$ showed to increase the expression of c-Fos, CREB, ATF, and HSP70, and maximal expression was occured at $3\sim6$ hr after E administration. P (1mg) also increased, but much less than E, the expression of c-Fos, ATF, and HSP70. However, P did not reveal any effect on the expression CREE. P treatment 4 hr after E injection decreased c-Fos, CREB, and ATF expression, but did not show any change in the E-induced HSP70 expression. In immunohistochemical study c-Fos-, CREB-, and ATF-immunoreactivities were confined to the cells of luminal epithelium of uterine endometrium. These results suggest that proliferation and differentiation of rat uterus during reproductive cycle may mediated via expression of transcription factors, such as c-Fos, CREB, ATF, and HSP70.

Non traumatic aseptic necrosis of the head of the femur is well documented with respect to its clinical roentgenographic and pathological aspect, but not with respect to etiology. A number of reports have associated various diseases and conditions with necrosis of the femoral head. Prominent among these are alcoholism, steroid therapy and hemostatic disorder. The increased incidence of avascular necrosis of bone associated with long-term corticosteroid therapy has aroused much interest. The pathogenesis of cortisone-induced avascular necrosis is as yet unproved. But cortisone-induced fatty liver with hyperlipidemia, leading to systemic embolization of fat and avascular necrosis of bone has much experimental support. We present a case of bilateral avascular necrosis of the femur head following several epidural steroid injections in a 30 year old male patient who had low back pain with radiation to both legs for 1 year and who had Cushinoid appearance for several months. One week later, he had a total replacement of both hip operation.
