A two-year-old, intact male, 45 kg Doberman Pinscher was referred with dermal nodular lesions affecting the left hindlimb. The cytological examination revealed eosinophilic inflammation. Skin biopsy specimens showed canine eosinophilic granuloma (CEG). The dog was administered oral prednisolone (1.5 mg/kg/day) and azathioprine (2 mg/kg/day). After one week, the skin lesions diminished dramatically, but the dog presented with severe watery diarrhea. The prednisolone dose was reduced by 0.9 mg/kg/day. The lesions and diarrhea improved markedly after one week. Prednisolone was tapered by 25% of the previous dose every week to 0.2 mg/kg/day. Azathioprine was also reduced to therapy every other day. After seven weeks of combination treatment, the medications were withdrawn, but the dog had a recurrence one week later. Azathioprine (2 mg/kg/EOD) was reintroduced for two weeks. There was no relapse after all the medications had been withdrawn. This case indicates that CEG can be managed with prednisolone and azathioprine. Azathioprine may be an effective adjunctive immunosuppressive agent, and may be considered as a well-tolerated prednisolone sparing agent to treat CEG.

Objectives: The aim of this study was to report a case of 43 year-old patient, diagnosed with missed abortion who previously failed to do spontaneous gestational sac expulsion in spite of 2 week-expectant-method, eventually succeeded with Traditional Korean Herb Medicine (TKHM) treatment only. Methods: In transabdominal sonography, gestational sac was not present at week 8. Due to the possibility of effect of medication on future pregnancy and post-surgery complications, D&C (Dilation & Curettage) as well as any other treatment was not done. Instead, she presented to our clinic. A combination of 2 main TKHMs was prescribed with 120-150 cc/dose (2 times per day for a week) : Gunggi-tang for helping expulsion of the dead fetus and placenta, and Wooseul-tang for treating retained placenta. Results: On day 6 of TKHM treatment, initiation of placenta expulsion was done. From day 8, hemorrhage started, lasting for 6 days. On day 10, placenta was expelled. On day 13, gestational sac and placenta were completely expelled. No infection, delayed bleeding, or pain was observed. After bleeding stopped, menorrhea started from week 7. Conclusions: This report implies a potential of TKHM as an optional and safe medication for the natural expulsion of conceptus in missed abortion.

432 Babcock ISA white leghorn pullets reared for 8 weeks on a standard managemental conditions were exposed to feed/nutrient and light restrictions from 9 to 20 weeks of age. Four feeding regimes i. e. 100, 85 or 70 percent of the recommended allowance and low energy (2,500 Kcal/kg) low protein (13% CP) ration were fed each in the three light regimes i. e. (A) Natural day light starting from 13.24 hr/day at 8 weeks of age and ending 10.41 hr/day at the end of 20 weeks; (B) Constant 11 hr/day light and (C) starting with 13 hr/day at 8 weeks and decreasing @ 20 min/week till 20 weeks of age. At the age of 20 weeks all the birds were shifted to separate cages under uniform lighting feeding and management. During the 21st week light was increased to 12 hr a day and thereafter with an increase of 30 min per week, increased to 16 hr a day at the age of 29 weeks. From 20 weeks onward till 72 week age, all the birds were offered commercial layer rations ad libitum, prepared according to climatic conditions. The results of the study revealed that birds reared under natural and constant light had higher weights than decreasing light, yet they could not out perform during production period. The effect of feed and nutrient restriction, on the other hand, was found significant during rearing as well as production period. The birds exposed to higher level of feed and those exposed to nutrient restriction were lighter in weight. The 100% fed birds laid their first egg at an early age. However, those reared on 85% of the recommendation excelled all other groups in terms of produced number of eggs, egg mass, hen housed and hen day production and net returns.

This study was conducted to investigate the repeated dose toxicity of DA-125, a new anthracycline antitumor antibiotic, in rats. Before the 13-week main study, a 4-week dose-range finding (DRF) study was carried out. The administration of DA-125 intravenously at dosage levels of 0, 0.125, 0.5, 2.0, and 8.0 mg/kg/day to rats for 4 weeks resulted in premature deaths of all animals in the 8.0 mg/kg/day group and in the deaths of 4 males and 4 females at 2.0 mg/kg/day. Body weights were markedly reduced in the 8.0 mg/kg/day group and showed dose-related decreases in all treatment groups when compared with the control group. Reductions in weight gain were slight and not significantly different at 0.125 mg/kg/day but animals receiving 0.5 mg/kg/day showed more marked decreases in gain in a clear dose-related manner Based On the results of the above DRF study, a 13-week repeated dose intravenous toxicity study in rats with DA-125 was performed at a dose level of 0, 0.012, 0.08 and 0.3 mg/kg/day. No treatment related effects were noted in behavior or body weight in all treatment groups. One male at the highest dose level died on study day 26, but the death could not be related to test article toxicity. Swelling and scabbing of the ears was present in all of the groups, including the control group. There were no treatment related changes in the hematological, biochemical or urinalysis values in all treatment groups. Thymus weights were significantly reduced ill males receiving 0.3 mg/kg/day and they were sligltly, and not significantly, reduced in females of the same group. While there were no associated histological changes. Treatment related necrosis was found in the tail vein (injection site) at 0.08 and 0.3 mg/kg/day. On the basis of these results, the no observed effect level (NOEL) was 0.012 mg/kg/day and the maximum tolerated dose (MTD) was estimated to be more than 0.3 mg/kg/day under the conditions tested.

Past literatures have not studied the impact of real-world events or information on the return and volatility of virtual currencies, particularly on the COVID-19 event, day-of-the-week effect, daily high-low price spreads and information flow rate. The study uses the ARMA-GARCH model to capture Bitcoin's return and conditional volatility, and explores the impact of information flow rate on conditional volatility in the Bitcoin market based on the Mixture Distribution Hypothesis (Clark, 1973). There were 3,064 samples collected during the period from 1^st of January 2012 to 20^th April, 2020. Empirical results show that in the Bitcoin market, a daily high-low price spread has a significant inverse relationship for daily return, and information flow rate has a significant positive relationship for condition volatility. The study supports a significant negative relationship between information asymmetry and daily return, and there is a significant positive relationship between daily trading volume and condition volatility. When Bitcoin trades on Saturday & Sunday, there is a significant reverse relationship for conditional volatility and there exists a day-of-the-week volatility effect. Under the impact of COVID-19 event, Bitcoin's condition volatility has increased significantly, indicating the risk of price changes. Finally, the Bitcoin's return has no impact on COVID-19 events and holidays (Saturday & Sunday).

This study investigates daily stock market anomalies in Chinese stock market, using nine most representative stock indices over an eleven year time period spanning from pre-financial crisis era to six years into the financial crisis. This research is the first to test the presence of the day of the week effect on stock returns in the Chinese stock exchanges during the financial crisis. We find that the day of week effects have been strongly significant in Chinese stock exchanges since 2004. However, unlike the previously found negative Monday effect and positive Friday effect in the U.S., Chinese stock market shows positive returns on Mondays and negative returns on Tuesdays. More importantly, the negative Tuesday effect is only significant after the inception of financial crisis. The results indicate a positive effect on Mondays and a negative effect on Thursdays. More importantly, we find a negative Tuesday effect during the financial crisis, which suggests a spillover of the Monday effect from the U.S. stock market. Our results shed some light on the degree of market efficiency in the largest emerging capital market in the world, and its increasingly close relationship with the U.S. capital market.

To investigate the energy, protein, lipid, and lactose intakes of breast-fed infants of lacto-ove-vegetarians, 25 infants(13 boys, 10 girls) were examined on the 0.5th, 1st, 2nd, and 3nd months of lactation. The amount of breast milk intake was determined by a test-weighing method, and the energy content of protein, lipid, and lactose was calculated using the Atwater factor. Thedaily energy intake for boys averaged 316, 436, 447, and 431kcal and that of girls averaged 284, 399, 401, and 390kcal during lactation, respectively. Average energy intake of boys from milk from 2nd week to the 3rd month postpartum was significantly higher than that of girls(p<0.05), because milk intake volume of boys was much higher than that of girls. The protein intake of boys on 2nd week-3rd month averaged 7.33g/day and that of girls averaged 6.29g/day. The lipid intake of 2nd week, months averaged 21.8g/day and that of girls averaged 20.1g/day. The lactose intake of boys averaged 45.48g/day, while that of girls averaged 41.09g/day. The mean intake of protein and lactose in boys was significantly higher than that of girls.

본 실험은 정식 후 단일처리전 장일처리 기간에 따른 온실재배 스프레이 절화국 Reagan Improved품종의 건물생산과 절화품질에 미치는 영향을 구명하기 위하여 네덜란드 Wageningen 대학의 유리온실 실험포에서 수행하였다. 정식 13-14일전에 피트블록에 삽목한 묘를 단위면적당 64줄기로 2000년 9월 6, 13, 20일에 각각 정식하였고, 2000년 9월 27일 모든 처리구에 단일처리를 실시하였다. 정식에서 최종조사일까지 장일처리 기간 3주 처리구에서는 84일이었고, 2주 처리구에서는 77일, 1주 처리구에서는 70일, 단일처리 후에 최종수확일까지는 63일이 소요되었다. 개화시기는 모든 처리구에서 동일하였다. 3주 장일처리구에서의 주당 꽃송이수는 1주 장일처리구에 비해 2개 더 많았고, 꽃의 생체중 및 건물중은 각각 식물 개체당 4g과 0.4g더 무거웠지만, 각 처리구별 꽃의 품질에는 큰 차이가 없었다. 최종건물생산량 ($g{\cdot}m^{-2}$ )은 3주 장일처리구에서 높고, 1주 장일처리구에서 가장 낮게 나타났다. 본 실험에서 단일처리 전 장일기간은 단일처리 후 개화시기에 영향을 주지 않았으며 꽃의 품질면에서도 큰 차이가 없었다. 반면 초장과 생체중은 장일 조건이 길수록 높았게 나타났으며, 누적 건물중도 3주 장일처리구에서 가장 높은 결과를 나타냈다. 장일처리 기간은 꽃 자체의 품질에 영향은 적었지만, 개체 생체중 및 초장에 매우 큰 영향을 미쳤으므로 단일처리전 장일처리 기간은 개체품질 및 연중재배 생산 시스템에서 균일한 품질을 생산하기 위해 장일처리 기간의 조절은 고품질의 국화생산에 중요한 요인으로 생각되었다..
