A 2-year-old spayed female Persian cat presented to Kangwon National University Veterinary Medical Teaching Hospital with pruritus and erythema on the tips of both ears, around the eyes, and in the caudal abdomen. This patient had previously been prescribed prednisolone, but did not respond positively to the treatment. A skin screening test revealed that there were no fleas or fungi, and that only cocci were present. Blood testing revealed no remarkable findings. The patient was prescribed antibiotics (amoxicillin-clavulanic acid 25 mg/kg for 2 weeks) with no prednisolone. After 2 weeks, clinical signs were alleviated and the skin screening test showed no signs of cocci. However, clinical signs recurred even with the prescription of antibiotics. Four weeks after the steroid-free interval, Malassezia spp. hypersensitivity was detected upon a serum allergy test, and pathological analysis confirmed eosinophilic and mastocytic superficial dermatitis in the caudal abdomen. Based on these results, we suspected allergic dermatitis and prescribed 7 mg/kg cyclosporine A once a day. After 3 weeks, clinical signs were resolved. Seven weeks after the first trial with cyclosporine A, we reduced the cyclosporine A dose to 7 mg/kg every other day. The patient's symptoms have since been well controlled for 6 months. This study suggests that cyclosporine A can be a good choice for treating cats with suspected allergic dermatitis that has not responded positively to steroid treatment.

The effects of an antiprogesterone (RU 486) and an antiestrogen (tamoxifen) on ovulatory response and oocyte morphology were examined in pregnant mare serum gonadotropin (PMSG)-primed immatare female rats (28 days of age): a comparison has been made on two different regirnens primed with a "control" dose (4 IU) and a "superovulatory" dose (40 IU) of PMSG. Females for control control regimen received three consecutive injections of lmg RU486, lmg tamoxifen, or vehicle at 24, 36 and 48hr, and were killed at 72l'r after PMSG. Animals for superovalatory regimen received lmg RU486, 2.5mg tamoxifen, or vehicle fouowlag the injection schedule comparable to control regimen, and were killed at 60 and 72hr after PMSG. Compared to vehicle group, there was a significant reduction in ovulatory response as judged by the proportion of rats ovulating andi or by the mean number of oocytes per rat for each treatment of RU486 and tamoxifen in both regimens. The activity of tamoxifen in inhibiting the ovulatory response was greater in control, but less in superovulatory regimen than that of RU486 based on the dose employed for each antisteroid. In both regimens, RU 486 did not have any effect 6n the changes in the proportion of degenerate oocytes as well as ovarian weight, well tamoxifen treatment resulted in a marked promotion of oocyte degeneration as well as a great reduction in ovarian weight, compared to each parameter of vehicle group. RU486 treatment in each regimen did not alter the serum levels of any steroid hormones observed. Howerver, tamoxifen treatment was associated with significant increases in serum 17$\beta$-estradiol and decreases in progesterone in both regimens; also significant increases in androgens in superovulatory regimen. The results illustrate the relative inhibitory activity of RU486 and tamoxifen indicating major steroid hormone involved in PMSG-induced ovulation: 17$\beta$-estradiol for control and progesterone for superovulatory regimen. It also appears that tamoxifen-associated elevation of circulating 17$\beta$-estradiol andi or androgens could be in part, a contributing factor to the promotion of oocyte degeneration presumably by producing a hostile oviductal environment after ovulation.ent after ovulation.

The present study was conducted to investigate the regulatory mechanism of plasminogen activators (PAs) activation by $17{\beta}$-estradiol ($E_2$) and progesterone ($P_4$) in porcine uterine epithelial cells (pUECs). pUECs were collected from porcine uterine horn and cultured at 80% confluence. Then, 0.1% (v/v) DMSO, 20 ng/mL $E_2$, and $P_4$ with or without fetal bovine serum (FBS) treated to cultured cells for 24 hours. The supernatants were used for measurement of PAs activity and expression of urokinase-type PA (uPA), tissue-type PA (tPA), uPA specific receptor (uPAR), and type-1 PA inhibitor (PAI-1) mRNA were analyzed by real-time PCR. The expression of PAs-related genes was not affect by steroid hormones in both of serum treatment groups. However, PAs activity was increased by treatment of $E_2$ compared to 0.1% DMSO treatment in serum-free group (p<0.05). Then, $E_2$ and $P_4$ were diluted with 0.002% (v/v) DMSO for reduction of its effect and treated to cultured cells without FBS. Only tPA mRNA was significantly increased by $E_2$ treatment (p<0.05). PAs activity was enhanced in $E_2$ treated group compared to control groups (p<0.05). These results indicate that serum-free condition is more proper to evaluate effect of steroid hormones and activation of PAs in pUECs was mainly regulated by estrogen. These regulation of PAs activation may be associated with uterine remodeling during pre-ovulatory phase in pigs, however, further studies are needed to investigate precise regulatory mechanism.

Purpose : There is no specific treatment guidelines for Henoch-$Sch{\ddot{o}}nlein$(HS) nephritis. Therefore we performed this study to observe the effect of long term steroid therapy combined with azathioprine Methods : Treatment protocols; 1) Steroid pulse therapy: methylprednisolon 30 mg/kg/dose, maximum 1 gm, intravenolisly 6 times for alternate day. 2) Oral steroid was given 2 mg/kg/day for 1 month, 1 mg/kg/day for following 1 month and alternate day oral steroid combined with azathioprine 2 mg/kg/day for 2 years. Results : Time period from HSP to onset of HS nephritis was between 2 weeks to 5 months with mean $7.4{\pm}7.4$ weeks. Clinical remission were seen in 4 cases out of 5 ($80\%$). Mean time period with disappearance of proteinuria and microscopic hematuria were $5{\pm}2.4$ month and $13.3{\pm}2.9$ month respectively. On pathologic findings by ISKDC, 3 cases were grade IIIb, 2 cases were grade IV in first kidney biopsies and showed pathologic improvement in follow up tidneybiopsiesafterlyearstreatment. Conclusion : As there is no definitive treatment for HS nephritis so far, our study of long term oral steroid therapy with azathioprine was effective in clinical and histologic aspect. Therefore further study in HS nephritis with in a large group will be needed in the future.

Purpose: To evaluate the effectiveness of steroid injection for treatment of simple bone cyst in adults. Materials and Methods: 11 patients who were able to be followed up from February 1998 to February 2003. These lesions were attained by needle aspiration or trepanation and 80 mg to 200 mg of Depo-medrol (methylprednisolone acetate, Shin Poong Pharm. Co., Korea) was injected. The follow-up roentgenograms were done every 2 weeks, and if there were no evidence of recovery, re-injection was done 8 weeks later. Injection has done maximally 5 times, and we evaluated the result with modified Neer, Pentimalli, Scaglietti and Sandra classification. Results: There were no cases in which one Injection was enough for full recovery, and 3 cases after 2 injections, 3 cases after 3 injections, 2 case after 5 injections had good result. but 2 cases after more than 5 injections did not show improvements and are currently under observation. One case showed a increase in size of the bone cyst after 2 injections of steroid and underwent curettage and autogenous bone graft. Overall outcomes by Pentimalli classification were good in One case, fair in 7 cases and poor in 3 cases at final follow-up. Conclusion: Local injection of steroids is effective method in adults and can be considered as a first line treatment modality.

Many etiological factors playa significant role in the development of tracheal stenosis; too high tracheostomy (Jackson, 1921), too small stoma (Greisen, 1966), the treatment with respirator using cuffed tube (Pearson et al., 1968; Lindholm, 1966; Bryce, 1972) and infection (Pearson, 1968). Although the incidence has been reduced due to development of surgical technique and antibiotics, the frequency of tracheal stenosis which produces symptoms after tracheostomy ranges from 1.5 per cent (Lindholm, 1967). In the management of the stenosis, mild cases are treated by mechanical dilatation with silicon tube or stent (Schmigelow, 1929; Montgomery, 1965) combined steroid (Birck, 1970), and in the cases of stenosis causes, these removed under the are bronchoscopy. But in severe stenosis, transverse resection with subsequent end-to-end anastomosis has been used in recent years (Pearson et al., 1968). During about 10 years, 1967 to 1977, a total of 23 patients with tracheal stenosis complicated among the 1, 514 tracheostomies have been treated in Severance Hospital. Now, we have obtained following conclusions by means of clinical analysis of 23 cases of tracheal stenosis. 1. The frequency of tracheal stenosis was 23 cases among 1, 514 cases of tracheostomy (1.5%). 2. Under the age of 5, these are 12 cases (52.2 %). 3. The sex incidence was comprised of 18 males and 5 females. 4. The duration of tracheostomy ranges from 4 days to 16 months. 5. The primary diseases requiring tracheostomy were following; central nerve system lesions 11 cases, upper air way obstruction 10 cases, extrinsic respiratory failure 2 cases. 6. Severe wound infections were only 2 cases. 7. The methods of treatment applied to tracheal stenosis were following; closed observation only 5 cases, nasotracheal intubation combined steroid 5 cases, T-tube stent combined steroid 3 cases, fenestration op. 4 cases, revision 4 cases and transverse resection and end-to-end anastomosis 2 cases.

The estrogen-mediated effect of mesenchymal stem cells (MSCs) is a highly critical factor for the clinical application of MSCs. However, the present study is conducted on MSCs derived from adult donors, which have different physiological status with steroid hormonal changes. Therefore, we explores the important role of $17{\beta}$-estradiol (E2) in MSCs derived from female and male newborn piglets (NF- and NM-pBMSCs), which are non-sexually matured donors with steroid hormones. The results revealed that in vitro treatment of MSCs with E2 improved cell proliferation, but the rates varied according to the gender of the newborn donors. Following in vitro treatment of newborn MSCs with E2, mRNA levels of Oct3/4 and Sox2 increased in both genders of MSCs and they may be correlated with both estrogen receptor ${\alpha}$ ($ER{\alpha}$) and $ER{\beta}$ in NF-pBMSCs, but NM-pBMSCs were only correlated with $ER{\alpha}$. Moreover, E2-treated NF-pBMSCs decreased in ${\beta}$-galactosidase activity but no influence on NM-pBMSCs. In E2-mediated differentiation capacity, E2 induced an increase in the osteogenic and chondrogenic abilities of both pBMSCs, but adipogenic ability may increased only in NF-pBMSCs. These results demonstrate that E2 could affect both genders of newborn donor-derived MSCs, but the regulatory role of E2 varies depending on gender-dependent characteristics even though the original newborn donors had not been affected by functional steroid hormones.

Purpose : Corticosteroid has been used as the mainstay therapy of childhood NS. But SIO is one of the serious complications of long-term steroid therapy, especially in growing children. Recently calcium, calcitonin, PTH, vitamin D and bisphosphonate has been used to treat or prevent SIO in adult, which is rare in children with NS. We studied the effect of $1{\alpha}-(OH)D_3$ and Pamidronate on SIO using dual energy X-ray absorptiometry (DEXA). Patients and methods : We studied thirty patients who admitted in the Dept. of Pediatrics of Kyung Hee Medical Hospital with NS. All patients was received longterm steroid therapy. There was no history of bone, liver, or endocrine disease. The samples, serum protein, albumin, BUN, creatinine, calcium, phosphorus, and BMD were obtained before and the six months after the dose of $1{\alpha}-(OH)D_3$ and Pamidronate, respectively Results : The mean age was $6.9{\pm}3.3\;and\;6.5{\pm}2.5$ years old. The mean duration of steroid therapy was $28.8{\pm}1.8\;and\;27.6{\pm}1.0$ months. The changes of serum protein, albumin, BUN, creatinine, calcium and phosphorus level between pre-treatment and post-treatment did not show statistical significance in both $1{\alpha}-(OH)D_3$ and Pamidronate treatment group. However, BMD was increased in both from $0.472{\pm}0.12\;and\;0.457{\pm}0.10\;g/cm^2\;to\;0.533{\pm}0.12$ and $0.529{\pm}0.09\;g/cm^2$ after treatment. (P<0.05) Conclusion : Both $1{\alpha}-(OH)D_3$ and Pamidronate appears to be effective in treating and preventing SIO in children with nephrotic syndrome requiring long-term steroid therapy.

Purpose: The purpose of this study was to analyze the effectiveness of local steroid injection for infraspinatus under ultrasonographic guidance in patients with posterior shoulder pain during horizontal adduction test. Materials and Methods: Twenty one cases of patients, from May 2013 to May 2014, showed positive horizontal adduction test were retrospectively analyzed. We performed ultrasonography-guided infraspinatus injection using steroid to these patients in the outpatient clinics. We evalulated results for visual analogue score (VAS) for pain, UCLA score for these patients before injection, following 3 months and 6 months after injection. Results: After ultrasonography-guided infraspinatus injection using steroid, there were clinically significant improvements in VAS and UCLA score at 3 month's follow-up period (p<0.05). But there were no significant differences in VAS and UCLA score between 3 months and 6 months (p>0.05). Fourteen of 21 (67%) cases showed much improved and improved satisfaction. Respectively, seven of 21 (33%) cases showed not improved and aggravation satisfaction. Conclusion: Ultrasonography-guided infraspinatus injection using steroid is an effective treatment method for the patients with exacerbated posterior shoulder pain during horizontal adduction test.
