In general, satisfactory results can be obtained by nonoperative means in the management of proximal femoral shaft fracture in children. Howerver, it is sometimes difficult to maintain the fracture alignment by the nonoperative means because of different muscle pulls in the thigh. The proximal fragment tend to be displaced and roentgenograms are difficult to be taken during traction. These problems have led some authors to advocate open reduction and internal fixation which facilitate overall care. We report our experiences on nonoperative and.operative treatment for proximal femoral fracture at the Chon-ju Presbyterian Medical Center from February 1987 to January 1991. The results are as follows ; 1. There were 20 cases in male, 7 cases in female. Average age at injury was 6.9 years (range, 6 months to 12 years and 8 months). Traffic accident was the most common cause (70.3%). 2. Average immobillization time was 9.2 weeks (range, 6.0 weeks to 12.1 weeks) in the nonoperative treatment group(17 cases), while 8.1 weeks(range, 6.1 weeks to 11.4 weeks) in the operative treatment group (10 cases). 3. Average bony union time was 9.6 weeks (range, 6.3 weeks to 12.5 weeks) in the nonoperative treatment group(17. cases) and 11.2 weeks (range, 9.0 weeks to 13.4 weeks) in the operative treatment group (P < 0.05). 4. Average overgrowth of femur was 3.3mm(range,

With simple abdomen, double contrast colon study, and ultrasongraphy, authors retrospectively analyzedradilogic findings of 46 cases which were proved periappendiceal abscess, due to perforation of appendix, byhistology or follow-up ultrasnongraphy from May in 1983 to July in 1985 at Yeung-Nam University Hospital. Theresuls obtained were as follows: 1. Of 46 cases, 24 cases were males and 22 cases females, with the results ofabove statistics, periappendiceal abscess was not influenced by sex. 2. Periappendiceal abscess was mostfrequently demonstrated in forties. 3. Comparison of ultrasonography and B.E. Pseudorenal pattern(Ultrasonography)- well defined defect (B.E.) Cystic pattern(Ultrasonography)- serrated defect (B.E.) 4. Missed 2 cases inultrasonography were detected in B.E., i.e. sensitivity of B.E. is higher than that of ultrasonography. 5.Differences of ultrasonography and B.E.

Prurigo pigmentosa(PP) is a rare dermatosis with an unknown cause characterized by intensely pruritic papules that resolve with reticulate pigmentation. It is a disease entitity commonly reported in Japan but seemingly rare in other parts of the world. We report 5 cases that clinically and histopathologically fulfilled the characterisitics of PP and were treated with dapsone resulting in significant clinical improvement.

6.EP2 Induces p38 Phosphorylation via the Activation of Src in HEK 293 Cells.
Biomolecules & Therapeutics 2015;23(6):539-548
Prostaglandin E2 (PGE2), a major product of cyclooxygenase, binds to four different prostaglandin E2 receptors (EP1, EP2, EP3, and EP4) which are G-protein coupled transmembrane receptors (GPCRs). Although GPCRs including EP receptors have been shown to be associated with their specific G proteins, recent evidences suggest that GPCRs can regulate MAPK signaling via non-G protein coupled pathways including Src. EP2 is differentially expressed in various tissues and the expression of EP2 is induced by extracellular stimuli. We hypothesized that an increased level of EP2 expression may affect MAPK signaling. The overexpression of EP2 in HEK 293 cells resulted in significant increase in intracellular cAMP levels response to treatment with butaprost, a specific EP2 agonist, while overexpression of EP2 alone did not increase intracellular cAMP levels. However, EP2 overexpression in the absence of PGE2 induced an increase in the level of p38 phosphorylation as well as the kinase activity of p38, suggesting that up-regulation of EP2 may promote p38 activation via non-G protein coupled pathway. Inhibition of Src completely blocked EP2-induced p38 phosphorylation and overexpression of Src increased the level of p38 phosphorylation, indicating that Src is upstream kinase for EP2-induced p38 phosphorylation. EP2 overexpression also increased the Src activity and EP2 protein was co-immunoprecipitated with Src. Furthermore, sequential co-immunoprecipitation studies showed that EP2, Src, and beta-arrestin can form a complex. Our study found a novel pathway in which EP2 is associated with Src, regulating p38 pathway.

BACKGROUND: Fraxetin (7,8-dihydroxy-6-methoxy coumarin), a coumarin derivative, has been reported to possess antioxidative, anti-inflammatory and neuroprotective effects. A number of recent observations suggest that the induction of heme oxygenase-1 (HO-1) inhibits inflammation and tumorigenesis. In the present study, we determined the effect of fraxetin on HO-1 expression in HaCaT human keratinocytes and investigated its underlying molecular mechanisms. METHODS: Reverse transcriptase-PCR and Western blot analysis were performed to detect HO-1 mRNA and protein expression, respectively. Cell viability was measured by the MTS test. The induction of intracellular reactive oxygen species (ROS) by fraxetin was evaluated by 2′,7′-dichlorofluorescin diacetate staining. RESULTS: Fraxetin upregulated mRNA and protein expression of HO-1. Incubation with fraxetin induced the localization of nuclear factor-erythroid-2-related factor-2 (Nrf2) in the nucleus and increased the antioxidant response element-reporter gene activity. Fraxetin also induced the phosphorylation of Akt and AMP-activated protein kinase (AMPK)α and diminished the expression of phosphatase and tensin homolog, a negative regulator of Akt. Pharmacological inhibition of Akt and AMPKα abrogated fraxetin-induced expression of HO-1 and nuclear localization of Nrf2. Furthermore, fraxetin generated ROS in a concentration-dependent manner. CONCLUSIONS: Fraxetin induces HO-1 expression through activation of Akt/Nrf2 or AMPKα/Nrf2 pathway in HaCaT cells.

The onset of systemic scleroderma in the first. decade of lif occurs in less than 1.5% of instances. Systemic sclerodrma in childhood have been characterized by less severe visceral involvement and a benign course We report a boy, aged 7 years, with a history of Raynaid; phenomenon and dysphagia. He had a mask-like face, flexion contracture of hands and knee joints, digital pitting scars, ichthyosiform skin change on leg and hyperpigrnented induration on all extremities and trunk. Antinuclear antibodies were positive in nucleolar type and Scl-70 antiocy was also present. On radiologie study, the pattern of reflux esophagitis and resorption of the listal ends of all phalanges were nated. Histopathological findings were compatible with sclerodma. He was treated with Penicillamine-D and oral corticosteroic with good improvernent.
