The clinical syndrome of acute optic neuritis(ON) has been known for many yearsthough its causes are still uncertain. Especially, the main focus is how often after a firstbout of isolated ON progress to multiple sclerosis in neurologic field. Therefore westudied and analysed 20 patients with acute optic neuritis for clinical features and prognosis and obtained the results as follows; 1. The male to female ratio was 1: 4. 2. The age at onset ranged from 9 to 70 years. 3. Unilateral involvement -of ON was detected in 10 cases (50%); the others were bilater al(10 cases, 50%). 4. Papillitis was present in 6 cases(30.2%) and the disk was normal(retrobulbar) in the other 7 cases (35%). 5. Recovery of vision was noted within 2 weeks in 8 eyes(34.8%) and in 19 eyes (82.2%) within 2 months. 6. The response to treatment in optic neuritis showed no definite difference between steroid group and conservative group. 7. The rate of ON evolving into multiple sclerosis was 10% in this series.

OBJECTIVE: To determine whether local estrogen production takes place in adenomyosis and in normal endometrium. METHODS: The study included 23 cases of adenomyosis and 17 cases of normal uterine endometrium obtained through hysterectomy or curettage at Kangnam Cha Hospital. The frozen tissue specimens were examined by immunohistochemistry using P450 arom. RESULTS: P450 arom was immunolocalized exclusively in the cytoplasm of glandular cells of adenomyotic tissue. However, no apparent staining was observed in stromal cells. Aromatase was expressed in the ectopic glands (82.6%), but also in the eutopic endometrium of patients with adenomyosis (23.5%). In the case of normal endometrium, P450arom was not detected. CONCLUSION: These results suggest that the aromatase activity is correlated to the pathophysiology of adenomyosis.

BACKGROUND: The multifocal hypointense cerebral lesions (MHCLs) on gradient echo (GE)-MRI and white matter changes on T2WI have been thought to be indicative of microangiopathy. The purpose of this study is to elucidate the relationship between MHCLs and white matter (WM) changes and the clinical significance of WM changes in stroke patients. METHODS: We retrospectively reviewed MRI and clinical data of 115 patients with stroke (56 female and 59 male). Periventricular and deep white matter hyperintensity (PVHI and DWMHI) were measured by semiquantative rating scale proposed by Mantyla. The round, hypointense signal, less than 7 mm in diameter on GE-MRI were counted as MHCLs. The association between risk factors of stroke and MHCLs on GE-MRI and sum of the white matter change scores and total number of MHCLs were analyzed, respectively. RESULTS: MHCLs on GE-MRI were significantly associated with old age (p<0.05) and hypertension (p<0.001) among risk factors of stroke. The distribution of MHCLs in subcortical area is associated with hypertension (p<0.05) and total number of MHCLs was significantly associated with sum of the white matter change scores (p<0.05). CONCLUSIONS: MHCLs on GE-MRI were significantly associated with severity of WM changes. Severe WM change may be an indicator of advanced small artery disease of the brain with an increased risk factor for bleeding. This should be taken into consideration when treating patients with stroke.

To evaluate the hepatotoxicity and nephrotoxicity of Galla Rhois (GR) toward the liver and kidney of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed after oral administration of 250, 500 and 1,000 mg/kg body weight/day of gallotannin-enriched extract of GR (GEGR) for 14 days. GEGR contained 68.7+/-2.5% of gallotannin, 25.3+/-0.9% of gallic acid and 4.4+/-0.1% of methyl gallate. Also, the level of malondialdehyde (MDA), a marker of lipid peroxidation, was decreased with 19% in the serum of high dose GEGR (HGEGR)-treated mice. The body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ among GEGR-treated groups and the vehicle-treated group. Furthermore, no significant increase was observed in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the GEGR-treated group relative to the vehicle-treated group. Moreover, the specific pathological features induced by most toxic compounds such as CCl4 were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that GEGR does not induce any specific toxicity in liver and kidney organs of ICR at doses of 1,000 mg/kg body weight/day, indicating that this is no observed adverse effect level (NOAEL).

Although formaldehyde (FA) is known to be a major allergen responsible for allergic contact dermatitis, there are conflicting reports regarding correlation between FA exposure and interleukin (IL-4) expression. To investigate whether allergic responses including IL-4 expression were induced by repeated dermal exposure to low dose FA, alterations in the luciferase signal and allergic phenotypes were measured in IL-4/Luc/CNS-1 transgenic (Tg) mice containing luciferase cDNA under control of the IL-4 promoter after exposure to 4% FA for 2 weeks. High levels of luciferase were detected in the abdominal region of the whole body and submandibular lymph node (SLN) of FA treated mice. Additionally, the ear thickness and IgE concentration were significantly upregulated in the FA treated group when compared with the acetone olive oil (AOO) treated group. FA treated mice showed enhanced auricular lymph node (ALN) weight, epidermis and dermis thickness, and infiltration of inflammatory cells. Furthermore, the expression of IL-6 among T helper 2 cytokines was higher in the FA treated group than the AOO treated group, while vascular endothelial growth factor (VEGF) levels remained constant. Overall, the results presented herein provide additional evidence that various allergic responses may be successfully induced in IL-4/Luc/CNS-1 Tg mice after exposure to low dose FA for 2 weeks. The luciferase signal under the IL-4 promoter may reflect general indicators of the allergic response induced by exposure to low dose FA.
