Drug-induced toxic epidermal necrolysis (TEN) is a bullous erythematous disease that is characterized by the appearance of scaled lesions and large sheets of pilling on the skin. A caseof TEN occured in a 10 month old female patient. The characteristic skin lesions of TEN developed after oral administration of carbamazepine for a partial seizure. Thig case consists of prodrome of malaise, fever, anorexia, and conjunctivity followed by erythema & flaccid bullae formation. Diagnosis was confirmed by histologic findings. This patient was treated with a massive systemic corticosteroid, antibiotics, fluid and electrolytes, and topical measures. Authors experienced an extremely rare case of TEN dur to carbamazepine, So report it with a brief review of literature.

The purpose of this study was to evaluate the painrelief effect of intra-artieular morphine after knee arthroscopy. First, the authors selected 20 general anesthetic patients and divided them equally into 2 groups ; the control group, and the morphine group. Second, at the end of knee arthroscopy, we injected 1mg of preservative free morphine in 20ml normal saline solution into knee joint cavity of the morphine group, while we injected only 20ml normal saline solution to the control group. And tourniquet was inflated above knee joint for ten minutes after injection in each patient. Third, we measured changes of systolic arterial blood pressure(SABP), diastolic arterial blood pressure(DABP), heart rate(HR), and respiratory rate(RR) before operation and at 1, 2, 3, 4, 5, 6, 12, 24 hour after knee arthroscopy. Fourth, we also measured visual analogue scale(VAS), requirement of supplemental analgesics, and systemic side effects of morphine. The results were as follows ; 1. SABP, HR, RR were increased significantly(p<0.05) at 1 hour after intra-articular injection in control group, but SABP, DABP, HR, RR were not changed signifieantly in morphine group. 2. VAS was decreased significantly(p<0.05) in morphine group compared with conrol group at each period after intra-articular injection. 3. Supplemental analgesics were not required in morphine group at all. With these results, we could conclude that intra-articular morphine is effective for pain relief after knee arthroscopy without any side effect.

The effects of Equiseti Herba Water-heating extract on the kidey & liver of rats were studied in 25 male Sprague-Dawley rats evenly divided into five groups, i.e., 5 rats each. The group I, which served as control and the group II, III, IV, were fed 300 mg/kg, 1000 mg/kg of Eqiseti Herba water-heating extract daily for one week, respectively. The group V was fed 1000 mg/kg of Equiseti Herba extract daily for two weeks. The effect of Equiseti Herba on the kidney and liver were determined by the measurements of the serum levels of BUN, creatinine, calcium, phosporus, sodium and potassium, total protein, albumin, transaminase (GOT & GPT) and cholesterol and 24hrs urine volume and GFR(ml/min), as well as by light microscopic and ultrastructural examinations of kidney and light microscopic examinations of liver in rats. The results were as follows; The groups II, III, IV were slightly higher than the control group on serum creatinine and potassium levels, but the group V was declined on serum creatinine and potassium levels, and 24hrs urine volume in spite of increased GFR. Histologically there was no remarkable changes in groups compared with the group I, except mild vacuolization of proximal convoluted tubule in group IV and V. These results suggested that equiseti Herba water-heating extract in rats induced reversible tubular changes on the kidney of rats. But the groups administrated by Equiseti Herba water-heating extract were not significantly higher than the control group on liver function test. Histologically there was no remarkable changes in groups II, III, IV & V compared with the group I.

The stiffness of cancer cells is attributable to intermediate filaments such as keratin. Perinuclear reorganization via phosphorylation of specific serine residue in keratin is implicated in the deformability of metastatic cancer cells including the human pancreatic carcinoma cell line (PANC-1). 12-O-Tetradecanoylphorbol-13-acetate (TPA) is a potent tumor promoter and protein kinase C (PKC) activator. However, its effects on phosphorylation and reorganization of keratin 8 (K8) are not well known. Therefore, we examined the underlying mechanism and effect of TPA on K8 phosphorylation and reorganization. TPA induced phosphorylation and reorganization of K8 and transglutaminase-2 (Tgase-2) expression in a time- and dose-dependent manner in PANC-1 cells. These effects peaked after 45 min and 100 nM of TPA treatment. We next investigated, using cystamine (CTM), Tgase inhibitor, and Tgase-2 gene silencing, Tgase-2's possible involvement in TPA-induced K8 phosphorylation and reorganization. We found that Tgase-2 gene silencing inhibited K8 phosphorylation and reorganization in PANC-1 cells. Tgase-2 gene silencing, we additionally discovered, suppressed TPA-induced migration of PANC-1 cells and Tgase-2 overexpression induced migration of PANC-1 cells. Overall, these results suggested that TPA induced K8 phosphorylation and reorganization via Tgase-2 expression in PANC-1 cells.

Advanced or metastatic breast cancer affects multiple organs and is a leading cause of cancer-related death. Cancer metastasis is associated with epithelial-mesenchymal metastasis (EMT). However, the specific signals that induce and regulate EMT in carcinoma cells remain unclear. PRR16/Largen is a cell size regulator that is independent of mTOR and Hippo signalling pathways. However, little is known about the role PRR16 plays in the EMT process. We found that the expression of PRR16 was increased in mesenchymal breast cancer cell lines. PRR16 overexpression induced EMT in MCF7 breast cancer cells and enhances migration and invasion. To determine how PRR16 induces EMT, the binding proteins for PRR16 were screened, revealing that PRR16 binds to Abl interactor 2 (ABI2). We then investigated whether ABI2 is involved in EMT. Gene silencing of ABI2 induces EMT, leading to enhanced migration and invasion. ABI2 is a gene that codes for a protein that interacts with ABL proto-oncogene 1 (ABL1) kinase. Therefore, we investigated whether the change in ABI2 expression affected the activation of ABL1 kinase. The knockdown of ABI2 and PRR16 overexpression increased the phosphorylation of Y412 in ABL1 kinase. Our results suggest that PRR16 may be involved in EMT by binding to ABI2 and interfering with its inhibition of ABL1 kinase. This indicates that ABL1 kinase inhibitors may be potential therapeutic agents for the treatment of PRR16-related breast cancer.

Melanogenesis is the production of melanin from tyrosine by a series of enzyme-catalyzed reactions, in which tyrosinase and DOPA oxidase play key roles. The melanin content in the skin determines skin pigmentation. Abnormalities in skin pigmentation lead to various skin pigmentation disorders. Recent research has shown that the expression of EMP2 is much lower in melanoma than in normal melanocytes, but its role in melanogenesis has not yet been elucidated. Therefore, we investigated the role of EMP2 in the melanogenesis of MNT1 human melanoma cells. We examined TRP-1, TRP-2, and TYR expression levels during melanogenesis in MNT1 melanoma cells by gene silencing of EMP2. Western blot and RT-PCR results confirmed that the expression levels of TYR and TRP-2 were decreased when EMP2 expression was knocked down by EMP2 siRNA in MNT1 cells, and these changes were reversed when EMP2 was overexpressed. We verified the EMP2 gene was knocked out of the cell line (EMP2 CRISPR/Cas9) by using a CRISPR/Cas9 system and found that the expression levels of TRP-2 and TYR were significantly lower in the EMP2 CRISPR/Cas9 cell lines. Loss of EMP2 also reduced migration and invasion of MNT1 melanoma cells. In addition, the melanosome transfer from the melanocytes to keratinocytes in the EMP2 KO cells cocultured with keratinocytes was reduced compared to the cells in the control coculture group. In conclusion, these results suggest that EMP2 is involved in melanogenesis via the regulation of TRP-2 expression.
