Gelatin 을 재료로 이용하는 식품의 폐기물에서 gelatin 을 액화시키는 능력이 특히 뛰어난 4종의 세균을 분리·동정하였으며, 배지내에 NaCI, KI·I₂, CuSO₄등의 억제제를 농도별로 처리했을때 나타나는 4균주의 생존도 및 액화능의 변화를 비교·검토하였고, 생존도에 미치는 pH의 영향도 조사하였다. 또한 MIC(Minimal Inhibitory Concentration) Test를 시행하여 항생제에 대한 4균주의 MIC도 조사하였다. 그 결과는 다음과 같다. 1. 4균주중 H strain은 Serratia liquefaciens로, Y₁strain은 Enterobacter속으로, Y₂와 Y₃strain 은 Pseudomonas 속으로 동정되었다. 2. 배지내에 억제제로 NaCl을 처리했을 경우, 7% 농도에서 생장이 100% 억제되었으며, KI·I₂처리시에는 20ppm 에서부터 생장이 억제되기 시작하여 100ppm에서는 4개의 균주 모두 100% 생장이 억제되었다. CuSO₄처리시에는 100ppm에서부터 억제효과를 나타내기 시작하여 300ppm에서는 거의 100% 억제 효과를 보였다. 생존도에 미치는 pH의 영향을 살펴본 결과, pH 5.0, 5.5, 6.0에서는 대조군과 동일한 생존도를 나타냈으나 pH 4.0, 4.5 에서는 100% 생장이 억제되었다. 분리 균주들의 액화능 비교에 있어서는 H strain 이 가장 뛰어난 액화능을 나타내었다. CuSO₄와 KI·I₂를 각각 3ppm, 10ppm의 저농도로 처리했을 경우 4균주의 액화능은 대체로 10∼20% 감소되었다. 3. 액화 능력이 가장 뛰어난 H strain 의 MIC 는 Penicillin G; 1∼5 ㎍/ml, Spectinomycin; 12.5∼25㎍/ml, Ampicillin; <0.05㎍/ml, Cefobid; <1㎍/ml, Claforan; 0.02∼0.3㎍/ml, Tetra-cycline; >10㎍/ml로 나타났다. Tetracycline을 제외한 5가지 항생제에 대하여 H strain이 Y strain들에 비해 민감한 것으로 나타났다. 그러나 Tetracycline의 경우에는 H strain이 Y strain들에 비하여 저항성을 갖는 것으로 나타났다. Four strains of gelatin-liquefying bacteria were isolated from the sewage of the food using gelatin as the material. Treated with various concentration of NaCl, KI-I₂and CuSO₄in the culture medium and with various gradient of pH, viability of the four strains was examined and compared with each other. And also, gelatin liquefying ability was investigated in the normal culture condition and in accordance with the concentration of the inhibitor. Morever, MIC(Minimal Inhibitory Concentration) test for these strains was also carried out. The results were as follows: 1. Of the four isolated strains, the H strain was identified as Serratia liquefaciens, Y₁as the genus Enterobacter, Y₂and Y₃strains as the genus Pseudomonas. 2. Treating the culture medium with NaCl as the growth inhibitor, 7% concentration of NaCl inhibited completely the viability of all the isolated strains. Adding KI-I₂solution to the medium at the level of 20ppm, viability began to decrease and the inhibitory effect was shown 100% at 100ppm. Treated with CuSO₄at the level of 10ppm, viability began to decrease, and at 300ppm growth inhibition showed almost 100%. There was no significant difference in viability according to the pH gradient at the range of 5.0-6.0. However, at pH 4.0 and 4.5, 100% inhibitory effect on the growth was shown. Considered with the ability of gelatin liquefaction, the H strain among the four strains had the most rapid and strong ability in gelatin liquefaction. (That is, about 23 times more effective in gelatin liquefaction than that of Y₁strain) 3. Considered the MIC test, the H strain was more sensitive to Penicillin G(1-5 ㎍/ml), Spectinomycin(12.5-25㎍/ml), Ampicillin(<0.05㎍/ml), Cefobid(<1㎍/ml) and Claforan (0.02-0.3㎍/ml) than to those of the strains. Compared with the other strains, the H strain was more insensitive up to the level of 10㎍/ml to the minimal inhibitory concentration of Tetracycline.

To make a objective diagnosis of the syndrome of cold-limbs, We investigated the 20 patients with cold limbs and GI trouble and 20 normal people as a control group. And we compared the thermal difference between Chon-jung(CV17) and Chung-wan(CV12 中脘), Chon-jung(CV17) and Ki-hae(氣海 CV6) and we compared the thermal differences of No-gung(PE8 勞宮) and Yong-chon(湧泉 KI1), too. The results were as follows. 1. All 20 patients had GI trouble and cold limbs. They had the symptom-Indigestion(16 cases-80%) with heart burn, tympanites, abdominal distention, hiccup, belching. Beside that symptom they also had constipation(6 cases-30%), diarrhea(3 cases-15%), headache & dizziness(6 cases-30%). And some had the menstrual syndrome, chronic fatigue, palpitation, insomnia, edema, arthralgia. 2. The thermal difference of the palms between the patients group and the control group were $25.70^{\circ}C,\;25.82^{\circ}C$, but they were not significant. 3. The thermal difference of the soles between the patients group and the control group were $23.58^{\circ}C,\;24.42^{\circ}C$ and the significancy was P=0.020 so it was significant(P<0.05). 4. The thermal difference of the palms and Chon-jung(CV17) between the patients group and the control group were $1.08^{\circ}C,\;0.76^{\circ}C$, but they were not significant. 5. The thermal difference of the sales and Chon-jung(CV17) between the patients group and the control group were $3.01^{\circ}C,\;1.90^{\circ}C$ and the significancy was P=0.003 so it was significant(P<0.05). 6. The thermal difference of Chon-jung(CV17) and Chung-wan(CV12 中脘) between the patients group and the control group was $0.30^{\circ}C,\;0.62^{\circ}C$ and the significancy was P=0.793 so it was significant(P<0.05). 7. The thermal difference of Chon-jung(CV17) and Ki-hae(CV6 氣海) between the patients group and the control group was $0.53^{\circ}C,\;0.68^{\circ}C$, but they were not significant. From the above, I could find the significance of D.I.T.I to diagnose the cold-feet not the cold-hands and the thermal difference between the trunk and limbs was more significant on cold-feet than on cold-hand, either.

Objectives: The purpose of this study is to evaluate the effectiveness of electroacupuncture on heat sensation of the feet of a 61-year-old female patient with restless leg syndrome. Methods: Electroacupuncture was performed at four acupoints (KI3 (太谿), KI6 (照海), LR3 (太衝), LR2 (行間)) selected to reduce heat sensation in both feet. The patient's symptoms were assessed using the VAS (Visual Analogue Scale), the SF-MPQ (short-form McGill Pain Questionnaire), and the IRLS (International Restless Legs Scale). The treatment was performed from April 20, 2010 to April 24, 2010. Results: During five sessions of electroacupuncture treatments, the VAS, SF-MPQ, and IRLS scores improved throughout the treatment period and afterwards. Conclusions: The results suggest that electroacupuncture at KI3(太谿), KI6(照海), LR3(太衝), LR2(行間) can be effective for reducing hot flush in both feet.

<P>Anticancer activity of silibinin, a flavonoid, has been demonstrated in various cancer cell types. However, the underlying mechanisms were not elucidated in human ovarian cancer cells. The present study was undertaken to examine the effect of silibinin <I>in vitro</I> and <I>in vivo</I> on tumor growth in human ovarian cancer cells. Silibinin decreased cell viability in a dose- and time-dependent manner. Silibinin caused an increase in reactive oxygen species (ROS) generation, and the silibinin-induced cell death was prevented by the antioxidant <I>N</I>-acetylcysteine (NAC). Western blot analysis showed silibinin-induced downregulation of extracellular signal-regulated kinase (ERK) and Akt. Transfection of constitutively active forms of MEK and Akt prevented the silibinin-induced cell death. Oral administration of silibinin in animals with subcutaneous A2780 cells reduced tumor volume. Subsequent tumor tissue analysis showed that silibinin treatment induced a decrease in Ki-67-positive cells, an increase in transferase-mediated dUTP nick end labeling (TUNEL)-positive cells, activation of caspase-3, and inhibition of p-ERK and p-Akt. These results indicate that silibinin reduces tumor growth through inhibition of ERK and Akt in human ovarian cancer cells. These data suggest that silibinin may serve as a potential therapeutic agent for human ovarian cancers.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2013/jafcau.2013.61.issue-17/jf400192v/production/images/medium/jf-2013-00192v_0008.gif'></P>

<P>Benzyl isothiocyanate (BITC) is a hydrolysis product of glucotropaeolin, a compound found in cruciferous vegetables, and has been shown to have anti-tumor properties. In the present study, we investigated whether BITC inhibits the development of prostate cancer in the transgenic adenocarcinoma mouse prostate (TRAMP) mice. Five-week old, male TRAMP mice and their nontransgenic littermates were gavage-fed with 0, 5, or 10 mg/kg of BITC every day for 19 weeks. The weight of the genitourinary tract increased markedly in TRAMP mice and this increase was suppressed significantly by BITC feeding. H and E staining of the dorsolateral lobes of the prostate demonstrated that well-differentiated carcinoma (WDC) was a predominant feature in the TRAMP mice. The number of lobes with WDC was reduced by BITC feeding while that of lobes with prostatic intraepithelial neoplasia was increased. BITC feeding reduced the number of cells expressing Ki67 (a proliferation marker), cyclin A, cyclin D1, and cyclin-dependent kinase (CDK)2 in the prostatic tissue. <I>In vitro</I> cell culture results revealed that BITC decreased DNA synthesis, as well as CDK2 and CDK4 activity in TRAMP-C2 mouse prostate cancer cells. These results indicate that inhibition of cell cycle progression contributes to the inhibition of prostate cancer development in TRAMP mice treated with BITC.</P>

In this study 8 male athletes and 8 female athletes for matches requiring endurance were examined for the purpose of comparison and analysis on the effect of absorption of sugars and effect of absorption of sugars+protein+fats restoration of muscular glycogen after elapse of 4 hours subsequent to closing 90 minutes exercise. (Amount of energy absorbed was same). Examinees were tested with 3 kinds of performance such as CPF Performance whereby they were made to take ① sugars (0.75 g/㎏) and protein (0.1g/㎏) and fats (0.02 g/㎏) after elapse of 1 hour subsequent to long hours of exercise and CHO Performance whereby examines were made to take ② sugars (1g/㎏) alone and Performance whereby they were made to take ③ placebo (which does not contain any sugars, protein or fats). Also the examinees took meals which had same amount of energy and nitrogen during the Performance on the date prior to experiment or on the date of experiment. Women during the exercise showed significantly higher rate of oxidation of fats, basic element of energy than that of men. In CHO Performance and CPF Performance value of blood sugar and density of insulin were significantly higher in comparison with performance with placebo. At such cases there was no difference between different genders. Same kind of phenomena were confirmed with restoration of muscular glycogen. From such fact it could be observed that absorption of fats alone and absorption of sugars+protein+fats in comparison with absorption of placebo after exercise promoted relatively higher level of restoration of muscular glycogen for both men and women.

In this report, we present a case of the male pseudohermaphrodite in a beagle dog. The animal was subjected for examination due to enlargement of clitoris that was shown as reddish finger-like structure protruding from the vulva. Visual examination of the internal genitalia revealed that the animal possessed both testes and uterus. Based on the findings of physical examination and exploratory laparotomy, it was tentatively diagnosed as male pseudohermaphrodite. Internal genitalia and enlarged clitoris were removed for the prevention of pyometra and Sertoli cell tumor.

<P>Concurrent chemotherapy with radiotherapy (CCRT) has been applied for the treatment of advanced stage of head and neck cancer patients. However CCRT is associated with several complications including mucositis, dermatitis, stomatitis, etc. This study was conducted to evaluate the therapeutic effect of systemically administrated recombinant human epidermal growth factor (rhEGF) in CCRT-induced oral mucositis in a mouse model. Oral mucositis was induced in male BALB/c mice through combination treatment with cisplatin (11 mg/kg, i.p.) and irradiation (17 Gy) of the head and neck area. rhEGF (1.0 mg/kg/day for consecutive 3 days) was administered systemically, and the therapeutic effect was determined by histological evaluation of the oral mucosa. To elucidate optimal dose of rhEGF on CCRT-induced mucositis, various concentrations (0.04–3 mg/kg) of rhEGF were injected for 3 days. Systemic rhEGF administration accelerated the recovery of body weight. Histologically, rhEGF-treated mice showed significantly increased epithelial cell layer thickness, basal cell number, and expression of Ki-67 compared to control mice. Most effective dose was 1 mg/kg among other doses tested. Systemic administration of 1 mg/kg of rhEGF reduces the severity of oral mucositis induced by CCRT in a mouse model, suggesting that rhEGF can be used for treating CCRT-induced mucositis during the cancer treatment.</P>
