Idiopathic hypertrophic pachymeningitis (IHP) is a rare disease involving localized inflammatory thickening of the intracranial or spinal dura mater without an identified cause. Seizure is a very unusual presentation of IHP. We present a 58-year-old-female patient with seizures caused by IHP. This case indicates that although IHP is rare, it has the potential to cause seizures.

Five secoiridoids (1-3, 5, 10), a iridoid (4) three flavonol glycosides (7-9) and a coumarin (6), were isolated from the flowers of Hydrangea paniculata. Their chemical structures were elucidated as kingiside (1), morroniside (2), sweroside (3), loganin (4), vogeloside (5), umbelliferone (6), quercetin-3-O-sambubioside (7), quercetin-3-O-neohesperidoside (8), kaempferol 3-O-sambubioside (9) and secologanin dimethyl acetal (10), respectively, by spectroscopic analysis. All isolated compounds 1-10 were assessed for their ability to induce C2C12 myotube hypertrophy. Among them, loganin (4) and kaempferol 3-O-sambubioside (9) increase the diameter of C2C12 myotubes. All isolated compounds 1-10 were firstly reported from the flowers of Hydrangea paniculata, and the skeletal muscle hypertrophic activity of 4 and 9 was also reported for the first time.

Background: The ubiquitin-proteasome system (UPS) is an important pathway of proteolysis in pathologic hypertrophic cardiomyocytes. We hypothesize that MG132, a proteasome inhibitor, might prevent hypertrophic cardiomyopathy (CMP) by blocking the UPS. Nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) and androgen receptor (AR) have been reported to be mediators of CMP and heart failure. This study drew upon pathophysiologic studies and the analysis of $NF-{\kappa}B$ and AR to assess the cardioprotective effects of MG132 in a left ventricular hypertrophy (LVH) rat model. Methods: We constructed a transverse aortic constriction (TAC)-induced LVH rat model with 3 groups: sham (TAC-sham, n=10), control (TAC-cont, n=10), and MG132 administration (TAC-MG132, n=10). MG-132 (0.1 mg/kg) was injected for 4 weeks in the TAC-MG132 group. Pathophysiologic evaluations were performed and the expression of AR and $NF-{\kappa}B$ was measured in the left ventricle. Results: Fibrosis was prevalent in the pathologic examination of the TAC-cont model, and it was reduced in the TAC-MG132 group, although not significantly. Less expression of AR, but not $NF-{\kappa}B$, was found in the TAC-MG132 group than in the TAC-cont group (p<0.05). Conclusion: MG-132 was found to suppress AR in the TAC-CMP model by blocking the UPS, which reduced fibrosis. However, $NF-{\kappa}B$ expression levels were not related to UPS function.

Infantile hypertrophic pyloric stenosis (HPS) is a relatively common entity. A number of studies for the postoperative feeding schedule has been studied to allow for earlier hospital discharge and improve cost-effectiveness in the treatment of HPS. The purpose of this study was to compare 3 feeding-methods and to evaluate the usefulness of ad lib feeding for HPS. The authors retrospectively reviewed the records of 116 patients who underwent pyloromyotomy for HPS from 1995 to 2004. Three cases were excluded because of the duodenal perforation during pyloromyotomy. Three feeding-methods were defined as: Conventional feeding (>10 hours nothing by mouth and incremental feeding every 2 hours, C), Early feeding(for 4 to 8 hours nothing by mouth and incremental feeding every 2 hours, E), and Ad lib feeding (for 4 hours nothing by mouth and ad lib feeding, A). Time to normal feeing in C, E and A were $51{\pm}24$, $34{\pm}12$ and $24{\pm}6$ hours, respectively. Hospital-stay in C, E and A were $72{\pm}17$, $55{\pm}13$ and $43{\pm}12$ hours, respectively. There were statistically significant differences according to the method of feeding. Frequency of postoperative emesis in C, E and A were 38 %, 47 % and 53 %, but was not significant statistically. Ad lib feeding decreased time to normal feeding and hospital stay, and did not increase postoperative emesis. We conclude that ad lib feeding is recommended for patient with pyloromyotomy in HPS.

Infantile hypertrophic pyloric stenosis(IHPS) is common in full-term babies, and relatively rare in prematures. The diagnosis of IHPS in premature infants may be obscured because of the lack of classic symptoms and signs and the absence of the standard criteria for ultrasonic diagnosis. The purpose of this study is to discover the clinical differences between premature and full-term infants with pyloric stenosis, and determine the appropriate diagnostic methods for early diagnosis in premature infants. The clinical records of 52 IHPS patients who had been operated upon from October, 1994 to April, 1997 were reviewed. The incidence of IHPS in premature infants was 25 %. The onset of symptom was 4.7 weeks of age in premature, and 2.9 weeks in full-term babies. Diagnosis was established by typical symptoms. signs. and diagnostic imaging studies. In two premature infants, diagnosis was confirmed by upper gastrointestinal(GI) series, because ultrasonography did not meet the diagnostic criteria. Two premature infants initially diagnosed as gastroesophageal reflux by esophagography. were found to have IHPS by upper GI series. For the diagnosis of IHPS, a new set of criteria for premature babies has to be developed.

폼페병은 상염색체 열성으로 유전되는 질환으로 GAA 효소의 결핍에 의해 심장과 골격근 조직의 라이소좀과 세포질에 당원이 축적된다. 전형적 영아형 폼페병은 심비대, 호흡부전, 근긴장 저하가 발생하고, 대부분 심폐 부전이나 호흡기 감염으로 1-2세 경에 사망에 이른다. 비전형적 영아형은 상대적으로 임상 양상이 경하고 진행이 느리다. 저자들은 영아기에 심근병증을 진단받고 서서히 근위부 근력의 약화가 진행되었던 남매에서 근생검, 효소 활성도 분석 및 GAA 유전자 분석으로 확진된 비전형적 영아형 폼페병을 경험하였기에 보고하는 바이다.

The purpose of this study was to investigate the early effects of irradiation on the temporomandibular joint in rats. Male rats were singly irradiated with the dose of 5 Gy or 10 Gy to their head and neck region by /sup 60/Co X ray. Experimental animals were sacrificed at each of the following time intervals -1, 2, 3, 5, 7 and 14 days. The specimens were examined with a light microscope, and treated with H & E staining and immuno-histochemical staining. The results were as follows, 1. By light microscopic findings, proliferative and hypertrophic zone were narrowed and hematopoietic cells were few in number at 5 days after irradiation. Repair signs were seen at 7 days after irradiation when decrease in osteoclast, increase in hematopoietic cells and increase of proliferative zone were noted. The 10 Gy irradiated group showed more severe histopathologic change than the 5 Gy group, and their repair was more slow. 2. In the S -100 antibody, positive cells were examined in the glenoid fossa. Positive cells of irradiated group showed more slight decrease in number than the control group. Low radiosensitivity and slow repair was noted in the glenoid foosa. 3. The interarticular disc was high radioresistant, and any histopathologic changes were not seen in disc. 4. Repair was examined clearly with the response to the antibodies. Especially by 5 days after irradiation 5 Gy group showed S-l00 positive cells in hypertrophic zone next to proliferative zone, chondroitin-4-sulfate positive cell in erosive zone next to hypertrophic zone, type-1 collagen positive cell in subchondral bone.

To explore the role of histone deactylase (HDAC) activation in an in vivo model of hypertrophy, we studied the effects of Trichostatin A (TSA). TSA subjected to thoracic aortic banding (TAB)-induced pressure stress in mice. In histological observations, TAB in treated mice showed a significant hypertrophic response, whereas the sham operation remained nearly normal structure with partially blunted hypertrophy. TSA treatment had no effect (measured as HW/BW) on sham-operated animals. TAB animals treated with vehicle manifested a robust ~50% hypertrophic response (p<0.05 vs sham). TAB mice treated with 2 mg/kg/day TSA manifested a blunted growth responses, which was significantly diminished (p<0.05) compared with vehicle-treated TAB mice. TAB mice treated with a lower dose of TSA (0.5 mg/kg/day) manifested a similar blunting of hypertrophic growth (~25% increase in heart mass). Furthermore, to determine activity duration of TSA in vitro, 1 nM TSA was added to H9c2 cells. Histone acetylation was initiated at 4 hr after treatment, and it was peak up to 18 hr, then followed by significantly reduced to 30 hr. We also analyzed the expression of p53 following TSA treatment, wherein p53 expression was elevated at 4 hr, and it was maintained to 24 hr after treatment. ERK was activated at 8 hr, and maintained till 30 hr after treatment suggesting an intracellular signaling interaction between TSA and p53 expression Taken together, it is suggested that HDAC activation is required for pressure-overload growth of the heart. Eventually, these data suggest that histone acetylation may be a novel target for therapeutic intervention in pressure-overloaded cardiac hypertrophy.
