Background: The objective of this study was to describe the extent of pain relief after an epidural steroid injection in the patients suffering from chronic low back pain from herniated disks or lumbar spinal stenosis. Methods: The study was prospectively designed for patients suffering with lumbar spinal stenosis (LSS) and herniated disks (HD) who were referred to a hospital-based pain clinic for epidural steroid injections (ESI). The pain was assessed with using a visual analog scale at baseline, two weeks after the first ESI and two weeks after the third ESI. Results: Eighty patients were enrolled, and all of them provided pain ratings before and after the injections. The LSS patients seemed to improve less than did the HD patients. The results showed no significant differences in the triamcinolone dosage and the frequency of injections for determining the efficacy of ESI. Conclusions: The LSS patients tended to have a less effective respond to ESIs than did the HD patients. The unsatisfactory response to ESI by the LSS patients underscores the need for randomized controlled trials of performing ESI in this population.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a relapsing-remitting disorder for which steroid administration is a key to control the progression. CLIPPERS can exhibit radiological features similar to malignant lymphoma, whose diagnosis is confounded by prior steroid administration. We report a case of CLIPPERS accompanied by abnormal elevation of ${\beta}-2$ microglobulin in the cerebrospinal fluid (CSF). A 62-year-old man started to experience numbness in all fingers of his left hand one year ago, which gradually extended to his body trunk and legs on both sides. Magnetic resonance imaging demonstrated numerous small enhancing spots scattered in his brain and spinal cord. CSF levels of ${\beta}-2$ microglobulin were elevated; although this often indicates central nervous system involvement in leukemia and lymphoma, the lesions were diagnosed as CLIPPERS based on the pathological findings from a biopsy specimen. We emphasize the importance of biopsy to differentiate between CLIPPERS and malignant lymphoma because the temporary radiological response to steroid might be the same in both diseases but the treatment strategies regarding the use of steroid are quite different.

Steroid $\Delta^1$-dehydrogenase which introduces a double bond into the 1, 2 positions of steroid ring A was purified from Arthrobacter simplex, an excellent biotransformer of hydrocortisone into prednisolone. Hydrocortisone-induced cells were disrupted by vigorous agitation with glass beads, and a solubilized enzyme was obtained after centrifugation at 100, 000$\times$g for 90 minutes. The enzyme was purified 123-fold in three steps of chromatographic procedures with 13% yield. The last step of testosterone-agarose affinity column decisively contributed to the successful purification. The molecular weight of the enzyme was estimated to be 98, 000 by SDS-PAGE and 100, 000 by gel filtration, indicating that this enzyme behaves as a monomer. The enzyme showed demands for artificial electron acceptor, and among the several reagents tested, phenazine methosulfate acted as the most effective electron acceptor. Subcellular distribution of this enzyme was studied by centrifugation experiment. Comparison of the enzyme activities in pelleted membrane and cytosol fractions suggests that the enzyme may be a weakly attached peripheral membrane protein in vivo. But considerable amounts of enzyme was solubilized without any additional treatments for membrane protein.

Cervical epidural steroid injection is indicated for radicular symptoms with or without axial neck pain. Complications are rare but can be serious. Here, we report the case of a 54-year-old man with cervical radicular pain who was treated with cervical epidural steroid injection. Injection was administered twice under fluoroscopic guidance with the loss-of-resistance technique using air to confirm the epidural space. After the second procedure, the patient complained of severe persistent headache and was diagnosed with pneumocephalus on brain computed tomography. The patient returned home without any neurological complication, after a few days of conservative treatment. Though, a fluoroscopic guidance cervical epidural injection is also known to diminish the risk of complications. Physicians should always keep in mind that it does not guarantee safety, particularly in the cervical region, related to its anatomical considerations.

The effects of total ginseng saponin. extracts of Panax ginseng C.A. Meyer, on the differentiation of F9 teratocarcinoma stem cells were studied. F9 stem cells cultured in the presence of ginseng saponin together with dibutyric cAMP became parietal endoderm - like cells. Moreover, the expressions of differentiation marker genes. laminin. type IV collagen. and retinoic acid $receptor-{\beta}(RAR{\beta})$ were increased after treatment of ginseng saponin. Among various ginsenosides purified from crude ginseng saponin, $Rh_1\;and\;Rh_2$ caused the differentiation of F9 cells most effectively. Since ginsenosides and steroid hormone show resemblance in chemical structure. we studied the possibility of the involvement of a steroid receptor in the differentiation process induced by ginsenosides. According to Southwestern blot analysis, a 94 kDa protein regarding as a steroid receptor was detected in F9 cells cultured in the medium containing ginseng saponin. Based on these data, we suggest that ginseng saponin, especially ginsenosides $Rh_1\;and\;Rh_2$ cause the differentiation of F9 cells and the effects of ginsenosides might be exerted via binding with a steroid receptor or its analogous nuclear receptor.

In childhood systemic lupus erythematosus patients, renal involvement is closely related to mortality and morbidity of the disease. Therefore early diagnosis and treatment are essential to improving prognosis. We saw a child who had hematuria, albuminuria, anorexia, fatigue, and light hyper sensitiveness. He was diagnosed as lupus nephritis (WHO Class II+IV) and treated with ACE inhibitor and steroid therapy for 12 months. However, clinical improvement was not shown. So we treated him with herbal formula (Jasinwhalhyul-tang: Zishenhuoxue-tang) and steroid therapy. After 17 months of treatment, hematuria disappeared and clinical symptoms and albuminuria had improved significantly.

The key targets of endocrine disruptors are nuclear hormone receptors, which bind to steroid hormones and regulate their gene transcription. A yeast-based steroid hormone receptor gene trascription assay was previously developed for the evaluation of chemicals with endocrine modulating activity. The yeast transformants used in this assay contain the human estrogen receptor along with the appropriate steroid response elements upstream of the $\beta$-galactosidase reporter gene. We tried to evaluate several natural and synthetic steroids of their potential to interact directly with the steroid receptor. Some putative endocrine disruptors, including nonylphenol, are weakly estrogenic. But the combined treatment oj these chemicals with di-(2-ethylhexyl)phthalate (DEHP) significantly increased the $\beta$-galactosidase activity in the yeast transformant. These results suggest that we also have to consider the synergistic effects of endocrine disruptors. In this study, we showed that yeast-based bioassay is a valuable tool for screening potential endocrine disruptors and quantitative determination of estrogenicity. And the possibility that the estrogen receptor binds multiple environmental chemicals adds another level of complexity to the interaction between the endocrine disruptors and the human hormone system.

Steroid sulfatase (STS) is responsible for the conversion of estrone sulfate to estrone that can stimulate growth in endocrine-dependent tumors such as prostate cancer. Although STS is considered as a therapeutic target for the estrogen-dependent diseases, cellular function of STS are still not clear. Previously, we found that tumor necrosis factor (TNF)-${\alpha}$ significantly enhances steroid sulfatase expression in PC-3 human prostate cancer cells through PI3K/Akt-dependent pathways. Here, we studied whether bacterial lipopolysaccharides (LPS) which are known to induce TNF-${\alpha}$ may increase STS expression. Treatment with LPS in PC-3 cells induced STS mRNA and protein in concentration- and time-dependent manners. Using luciferase reporter assay, we found that LPS enhanced STS promoter activity. Moreover, STS expression induced by LPS increased PC-3 tumor cell migration determined by wound healing assay. We investigated that LPS induced IL-6 expression and IL-6 increased STS expression. Taken together, these data strongly suggest that LPS induces STS expression through IL-6 pathway in human prostate cancer cells.

This study was performed to examine if the effects of collagen supplementation from pork skin could improve the sex steroid hormone, serum lipid and skin crack in Korean middle-aged women. Middle-aged women (40-55 years) who were not diagnosed with any type of disease were included in this study and thirty subjects were randomly assigned to a control group (n = 15) or a collagen supplemented group (n = 15). The collagen supplemented group ingested collagen flour 2 g, 3 times a day for 12 weeks. We measured serum collagen, estrogen, estradiol, estriol, progesterone, total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol concentration. The collagen supplementation group had significantly increased serum collagen (p < 0.05) compared with the control group. In addition, skin crack was improved. But, there were no differences for sex steroid hormone and lipid profile in control and collagen supplemented groups. The result of the present study demonstrated that supplementation of 6 g collagen per day for 12 weeks can give beneficial effects on skin crack reduction and serum collagen concentration.
