The correlation between primary Si and silicide refinement induced by ultrasonic treatment (UST) of multicomponent Al–Sialloy containing Ti, Zr, V, and P was investigated. UST significantly refined the primary Si phase owing to cavitation-inducedwetting and deagglomeration of MgAl2O4particles. Lowering the UST finish temperature caused deterioration of the degreeof primary Si refinement, instead leading to silicide refinement. Cavitation-induced silicide nucleation on wetted MgAl2O4consumed the MgAl2O4particles, particularly in the case of primary Si nucleation. Similarly, the formation of an AlP phaseon the silicide phase reduced the nucleation efficiency of the AlP phase. Poisoning of the MgAl2O4and AlP phases by thesilicide phase was responsible for the deterioration in primary Si refinement. Room-temperature tensile strength and hightemperatureelongation were increased by UST and were dependent on the size of primary Si.
A Thirteen-week Oral Dose Subchronic Toxicity Study of Isaria sinclairii in Rats
Ahn, Mi-Young,Han, Jea-Woong,Jee, Sang-Deok,Hwang, Jae-Sam,Hwang, Seok-Jo,Hong, Yoo-Na,Kim, Sung-Nam Korean Society of ToxicologyKorea Environmental Mu 2007 Toxicological Research Vol.23 No.4
Isaria sinelairii (IS) was orally administered at doses of 0, 0.04, 0.2, and 1 g/kg/day over a 13-week period. There were no observed clinical signs or deaths related to treatment in all the groups tested. Therefore, the approximate lethal oral dose of I. sinclairii was considered to be higher than 1 g/kg in rats. Throughout the administration periods, no significant changes in diet consumption, ophthalmologic findings, organ weight, clinical pathology (hematology, clinical chemistry, coagulation, and urinalysis) or gross pathology were detected. Minor changes were found in hematological parameters for the 0.04 g/kg/day and 0.2 g/kg/day IS treated groups (triglyceride reductions of $20.1{\sim}46.6%$ and platelet increases), but all changes were within physiological range. Microscopic examination failed to identify any treatment-related histopathologic changes in the organs of the IS-treated rats other than nuclear enlargement (cellular atypia) of the tubular regions in the medulla of the kidney in the high dose group. From these results, one can conclude that the no-observed effect level (NOAEL) of I. sinclairii is less than 0.04 g/kg/day in rats.

Behcetsdisease is a chronic inflammatory disease characterized by oral ulcers, genital ulcers, uveitis, and skin lesions. Furthermore, Behcets disease can manifest as vascular lesions, such as, those of vasculitis, venous thrombosis, or thrombophlebitis or as an arterial aneurysm. Here, the authors report the case of a pulmonary artery aneurysm and deep vein thrombosis in a 41-year-old woman with a previous diagnosis of Behcets disease. The patient presented with hemoptysis and a cough, and was found to have a bleeding pulmonary artery aneurysm at the right lower lung. Pulmonary arteriography was performed and the aneurysm was embolized with coils. As a result, hemoptysis did not subsequently recur. However, five years later, deep vein thrombosis occurred in the left leg. Left leg pain improved after the regional infusion of thrombolytics.

Obesity is a major risk factor for cardiovascular disease. In our case study using animal models for disease states such as obesity or hypertension, we found that, Isaria sinclairii remarkably reduced body weight and ameliorated metabolic abnormalities in Zucker and SHR rats. Genetically obese (fa/fa) Zucker rats were one animal model chosen for this study. Four groups of rats received a standard diet and were treated orally with the following test samples daily for 8 weeks: saline (negative control), ethanol extracts of I. sinclairii, hot water extract of I. sinclairii, or $Xenical^{(R)}$ (30 mg/kg, positive control). Mild reductions (6.3%) in body weight gain were observed in the groups treated with the hot water extract of I. sinclairii compared to the control after 8 weeks. Interestingly, organ weight was greatly reduced by this Dongchunghacho (I. sinclairii), in parallel with the mild reductions in body weight gain and reductions in abdominal fat (adipose tissue). Also observed was a 4.1 % decrease in the ratio of heart weight/body weight compared to the control group. As a hypertensive animal model, SHR (spontaneously hypertensive rat) and WKY (Wistar Kyoto) rats were also administered these extracts for one month. Treatment with the hot water extract of I. sinclairii caused greater reductions in body weight gain for the SHR group (10.9%) compared to the WKY group's (5.2%). Based on these results, I. sinclairii extracts contain selective action for anti-obesity activity, naturally occurring candidate for regulation of body weight increase, as demonstrated in the present study.

The antioxidant activity of Isaria (Paecilomyces) sinclairii was determined by measuring its radical scavenging effect on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The n- BuOH extract of P. sinclairii showed strong scavenging activity to DPPH. The anti-oxidant potential of the individual fraction was in the order of ethylacetate> n- BuOH>chloroform>n-hexane. The n-BuOH soluble fraction exhibiting strong anti-oxidant activity was further purified by repeated silica gel column chromatography. N-(2-Hydroxyethyl)adenosine (HEA) was isolated as one of the active principles from the n-BuOH layer. The n-BuOH layer, particularly HEA, did not increase the level of nitric oxide (NO) production in vascular endothelial cells that might be related to vasorelaxation such as the action of viagra. In addition, the vascular endothelial growth factor (VEGF) levels showed little or no increase compared with control group with the treatment of I. sinclairii.

외상이나 종양의 제거 또는 구순열의 수술 후 발생하는 이차적인 입술의 변형은 그 변형된 형태나 부위 및 크기등에 따라 여러가지 교정방법이 개발되어 왔다.그러나 선천적이거나 또는 외상에 의한 이차적인 반흔형성으로 입술 전체의 폭이 좁아진 경우(narrow lip)나 입술이 얇아진 경우(thin lip)에 있어서는 그 교정이 쉽지 않다.특히 입술은 안면부의 다른 구조물과는 달리 특징적인 섬세함과 감각적인 미묘한 형태를 지니고 있기 때문에 입술의 교정에 있어서는 이러한 점을 염두에 두어야 한다.narrow lip의 교정을 위해 Lewis(1973)는 홍순(Vermilion)주위의 피부를 입술의 형태에 맞추어 일정양을 제거한 후 구순점막을 이용한 전전피판술(mucosal advancement flap)을 기술한 바가 있으며 만약 thin lip이 동반되어 있는 경우에는 홍순 주위의 피부의 상피층만을 제거한 후 구순점막과 점막하 조직을 이용한 전전피판술로 어느정도 입술부피를 얻을 수 있다고 하였다. 그러나 전기화상이나 방사선 조사등이 원인이 되어 발생한 thin lip인 경우에는 피하조직이나 점막하 조직등의 심한 반흔형성으로 인한 전술방법을 이용한 교정이 곤란하게 된다. 저자들은 생후 2 개월 당시 혈관종의 치료를 위해 방사선 치료를 받은 후 2차적인 반흔형성으로 얇아진 아래 입술을 교정하기 위해 내원한 18세의 여자 환자에서 구륜근 근피판을 이용한 수술 방법으로 상당히 만족스러운 결과를 얻었기에 보고하는 바이다.
