  • Blastocystis is an enteric Straminopile in tropical, subtropical and developing countries. Metronidazole has been a chemotheraputic for blastocystosis. Failures in its regimens were reported and necessitate new studies searching for alternative therapeutic agents. Aim of current study is to investigate potential effects of Atorvastatin (AVA) compared to the conventional chemotherapeutic MTZ in experimentally Blastocystis-infected mice. Anti-Blastocystis efficacy of AVA was evaluated parasitologically, histopathologically and by transmission electron microscopy using MTZ (10 mg/kg) as a control. Therapeutic efficacy of AVA were apparently dose-dependent. Regimens of AVA (20 and 40 mg/kg) proved effective against Blastocystis infections with highreduction in Blastocystis shedding (93.4-97.9%) compared to MTZ (79.3%). The highest reductions (98.1% and 99.4%)were recorded in groups of combination treatments AVA 20-40 mg/kg and MTZ 10 mg/kg. Blastocystis was nearly eradicated by the 20th day post infection. Genotype analysis revealed that genotype I was most susceptible, genotype III was less. Histopathologic and ultrastructural studies revealed apoptotic changes in Blastocystis and significant improvement of intestinal histopathological changes more remarkable in combinational therapy groups. Thus, the present study offers AVA as a potential candidate for Blastocystis therapy combined with MTZ.

  • In this study, we developed a fermented TMR producing system which could a continuous operation of baling and wrapping the mixed TMR. The baling part has fixed chamber of dia. 900 mm and width 900 mm. And the the turn-table type wrapping part is very compact compared to conventional one in market. The test result were: The absorbed power of the prototype in working was 9.0~15.7 kW. The combined baling and wrapping performance was over 20 bales/hr. The leakage in the process was around 1.9 kg for making a 350 kg TMR bale. The diameter of wrapped TMR bale was 900~950 mm, and its weight was 350 kg in average. Therefore the density was $718kg/m^3$, and it was very high density to the inputted TMR. The pH of the fermented TMR was 5.0~5.6 which was similar to the fermented haylage, also the TMR had no butyric acid's odor.

  • The antihypertensive effect of clonidine administered concurrently with labetalol or metoprolol were studied with spontaneously hypertensive rats (SHR). The changes of heart rate were also observed in the same rats. Every drug was orally administered single dose after prechecking the systolic blood pressure and heart rate of SHR. The blood pressure of SHR in concurrently administered group was more significantly decreased than in alone administered group. The effective and stable decrease of blood pressure was maintained at the group of clonidine with labetalol (0.05+50mg/kg) for 9 hours. The group of clonidine with metoprolol (0.05+100mg/kg) manifested more marked decrease of blood pressure than the group of metoprolol (100mg/kg) alone for 9 hours. The diminishing effect of heart rate was enhanced in group of administering clonidine with labetalol, decreasing the dose of labetalol from 50mg/kg via 25mg/kg to 12.5mg/kg. On the other hand, in the group that clonidine was administered concurrently with metoprolol, the diminishing effect of heart rate was decreased with decreasing doses of metoprolol from 100mg/kg via 50mg/kg to 25mg/kg.

  • The species composition and abundance variations of fishery resources in the adjacent marine ranching area, Tongyeong, Korea, were investigated by shrimp trawl, gill net, and longline during the period of July, September, and October in 2016. During the study period, the total catch were 8,522.9 kg with 34 species from the shrimp trawl, 32 species from the gill net, and nine species from the longline. The dominant species were different by gear, which were Hypodytes rubripinnis and Parapercis sexfasciata in the shrimp trawl, Platycephalus indicus and Raja kenojei in the gill net, and Conger myriaster and Scomber Japonicus in the longline. In terms of spatial distribution, Yongchodo showed the highest total catch in number as well as of in weight while Jukdo showed the lowest total catch in number and Bijindo showed the lowest total catch in weight. The amount of demersal fish resources in the survey area estimated as 301 ha, was 99,396 individuals which was converted to be 8,552.9 kg. The amount of demersal fish resources by gear were of trawling area, which area is 127 ha, were 76,251 and 3,489.5 kg, 74 ha in the gill net and longline survey area was 16,213 and 3,457.3 kg, and the other 100 ha area was 6,932 and 1,606.1 kg. In this study, the minimum resources for demersal fish is 61,687 and 4,265.2 kg, and the maximum is 149,439 and 14,197.9 kg.

  • Alzheimer's disease (AD) is characterized by amyloid deposition and associated loss of neunons in brain regions involved in learning and memory processes. Several causes of evidence support that the congnitive disturbance is closed associated with the deficit of cerebral acetylcholine neurotransmission, and the effect of carboxyl terminal 105 amino acid fragment (CT105) of the amyloid precursor protein (APP) on the gene expression of proinflammatory cytokines. We tested it on the scopolamine-induced amnesia model of the ICR mouse using the Morris water maze with repeated orally administration of 1st Green-Tea extract (200 mg/kg) and 2nd Green-Tea extract (200 mg/kg). The Green-Tea prevents impairment of learning and memory and neuronal loss in mouse models of cognitive disturbance and it demonstrated selectivity for inhibition of acetylcholinesterase (AChE). Furthermore, the repeated administration of Green-Tea, CT105-induced alzheimer's mouse model showed central cholinergic activity by ameliorates learning and memory impairment, and isolation of CD14 microglia showed significantly decreases intracellular release of the proinflammatory cytokines tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$ and reactive oxygen species (ROS). Because of its composite profile, oral therapeutic index and a prophylactic, Green-Tea is considered the better therapeutic candidate for the treatment of Alzheimer's disease.

  • The purpose of this study was to compare of muscles in clean and jerk techniques between 69kg class(n=3), 58kg class(n=3) in high school female weight lifters using EMG(electromyographic) system. EMG analysis were executed on 6 major muscles and dividing clean and jerk techniques into 6 phases. In that result, in the difference by weight, it was shown that EMG value increased gradually as the weight is raised of all muscles group & phases in 58kg class. In EMG signal scale by classes, it was shown that EMG signal scale didn't increase according to class & weight. In the result of this study, that EMG value was inconsistent in 69kg class is showing that the consideration of the technical factor together with muscle power has positive affect more on the performance improvement in the heavy class.

  • 새로운 간장질환 치료제로 개발중인 YH439가 orotic acid, nicotinamide 및 ethionine에 의해 유발되는 지방간에 대한보호 및 치료효과를 관찰하였다. 웅성 SD계 rat에 orotic acid(1%) 또는 nicotinamide(2%)가 첨가된 사료를2주간 섭취시켜 유발된 지방간에 대한 YH439의 보호 및 치료효과와 ethionine(100mg/kg, i.p.)투여로 유도되는 지방간에 대한 YM439의 보호효과를 관찰하기 위하여 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량을 측정하여 비교하였다. 그 결과, erotic acid 또는 nicotinamide의 섭취로 인해 랫드의 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량은 1.5-3배정도 증가하였으며, 이 증가된 지질들은 YH439 100, 200mg/kg 투여에 의해 유의성 있게 억제되었다. 또한 ethionine투여에 의해서도 랫드의 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량은 약 2배정도 증가되었으며, YH439 전저치에 의해 이 현상들이 억제되는 효과를 나타내었다.

  • Intra-articular injection of ELHLD peptide is considered to have a therapeutic effect in osteoarthritis (OA) through the inhibition of transforming growth factor-β1. This study aimed to assess the efficacy of intra-articular injections of high-dose ELHLD peptide (100 ㎍/kg) in canine stifle OA. Six client-owned dogs diagnosed with stifle OA were included. Selected dogs were treated with an intra-articular injection of high-dose ELHLD peptide (100 ㎍/kg). Outcome measures, including orthopedic examination, gait analysis, and Canine Brief Pain Inventory (CBPI) score, were evaluated four times after injection. Orthopedic examination, gait analysis, and owner's assessment (CBPI) improved significantly from 4 weeks after injection. In conclusion, we obtained sufficient evidence from this small sample that high-dose ELHLD peptide improves clinical signs of canine OA not only through subjective assessment but also through objective evaluation.
