Lumpy Skin Disease (LSD) and Foot-and-Mouth Disease (FMD) cause substantial economic losses on the livestock industry. Therefore, vaccinations have been implemented as the control strategy in endemic countries. However, the potential adverse effects of administering vaccines for both diseases simultaneously have not been thoroughly evaluated. The aim of this study was to assess the impact of vaccinating dairy cows with either or both LSD and FMD vaccines on milk production and physiological parameters such as milk temperature, rumination time and body weight. The experimental groups were divided into four according to the injection materials: 1) saline, 2) LSD vaccine, 3) FMD vaccine, and 4) both vaccines. The impact of vaccination on milk yield and physiological parameters was evaluated daily until 12 days post-vaccination, and milk components were analyzed twice, once per week. Among the experimental groups as well as each vaccine group, no statistically significant differences (p < 0.05) were observed at milk yield, milk components, or milk temperature. This suggests that simultaneous vaccination of LSD and FMD can be administered without adverse effects.

자생 부추속 식물 중 강부추(Allium thunbergii for. rheophytum ined.)와 갯부추(A. pseudojaponicum Makino)는 관상용, 식 용 및 약용자원으로 가치가 있으나 육묘를 위한 생육환경조건 구명이 미비하여 연구할 필요성이 있다. 본 연구는 강부추와 갯부추의 육묘에 미치는 플러그 셀 크기, 차광률, 시비처리에 따른 영향을 구명하기 위하여 실험을 수행하였다. 강부추와 갯부추를 육묘한 결과, 플러그 셀 크기에서는 50, 72, 105, 128, 162, 200셀 처리 중 용적이 가장 큰 50셀에서 초장, 엽 수, 근수, 그리고 근장의 생육이 우수하였다. 그러나 생산비용 과 플러그 육묘의 효율성을 고려하여 105셀 이상의 플러그 트레이 중에서 선택하여 육묘하는 것이 효과적이라 판단된다. 차광률에 따른 유묘는 0, 30, 60, 90% 처리 중 30~60% 차 광처리에서 초장, 근수, 그리고 근장이 유의적으로 높게 측정 되어 생육이 양호하였다. 시비처리에서 생중량과 건중량을 제 외한 생육지표를 검토했을 때, 강부추의 적정 시비처리는 속 효성 고형비료(DO-PRO) 0.1g, 갯부추는 속효성 액체비료 (Peters) 주 1회 8mL 엽면시비처리였고 두 종 모두 속효성 시비처리가 효과적이었다. 강부추와 갯부추의 초기 생육에는 30~60% 차광처리가 된 재배플롯에서 원예상토가 충진된 128셀 플러그 트레이에 종자를 파종한후, DO-PRO 0.1g 또 는 Peters 8mL를 주 1회 엽면시비하면서 재배하는 것이 효 과적이라 판단된다.

The development of drugs from natural plant sources is at growing interest due to the limitations of chemical drugs in terms of side effects and cost-effective factors of natural medicines. Among the various components contained in natural plant materials, flavonoids are of increasing interest because of their extended biological benefits. Flavonoids are classified into various types according to their structure and possess different activities depending on the structure. In this study, the flavonoids contained in Artemisia, native to Korea were examined and reviewed. HPLC chromatograms of three Artemisia species (Artemisia annua L., Artemisia iwayomogi and Artemisia argyi H.) were examined from published sources and their component analysis by MS data were summarized. The various flavonoids of Artemisia were classified into 12 types according to the main structure, and 10 flavonoids based on various activities were examined. The 10 flavonoids were identified as quercetin, kaempferol, rhamnetin, diosmetin, luteolin, methoxyflavone, catechin, apigenin, malvidin and genkwanin with extensive reported studies till date. The ten flavonoids examined have been reported to be effective in preventing and treating various diseases and exhibit activities such as anti-cancer, anti-inflammatory, antioxidant, antiviral, anti-obesity, anti-diabetic and anti-Alzheimer. The collective results from the reported studies suggest that the three types of Korean native Artemisia, contains various flavonoids with beneficial activities and may have therapeutic effects against diseases.

The kidney is a highly complex organ, and acute or chronic renal diseases can occur with various complications such as diabetes and hypertension. So far, no target specific treatment is available in acute or chronic renal failure, necessitating the development of alternative therapeutic strategy. Recent experimental findings suggest that the renal function and structure can be restored after being treated with various sources of stem/progenitor cells. In this review, we discuss up-to-date findings of the potential of renal progenitor/stem cells in alleviating renal injuries with a focus on preclinical studies. We also review cellular mechanisms underlying the therapeutic function of these cells.

루비깍지벌레 Ceroplastes rubens는 감귤에 피해를 주는 주요 깍지벌레 중 하나로 연 1회 발생하며 수액을 흡즙하는 직접적인 피해와 분비된 감로로 인한 그을음병 유발의 간접적인 피해가 발생하고 있다. 제주지역에서 루비깍지벌레 천적으로는 루비붉은깡충좀벌 Anicetus beneficus와 애홍점박이무당벌레 Chilocorus kuwanae 2종이 확인되었다. 1975년 일본에서 도입 방사한 천적인 루비붉은깡충좀벌이 현재까지 지속적으로 발생하고 있었으며, 루비깍지벌레 발생 억제에 영향을 미치고 있었다. 2018년 4월부터 12월까지 도내 유기재배 감귤원 (2개소)에서 황색끈끈이트랩을 이용 루비붉은깡충좀벌 성충의 시기별 발생양상을 조사한 결과 월동세대 성충은 5월 중순, 제1세대와 제2세대 성충은 각각 7월 중순과 8월 하순에 발생 정점을 나타내었다. 조사 포장에서 루비깍지벌레의 기생률은 9월 중순에 9.6%와 19.6%이었다.

Sow longevity is important for efficient and profitable pig farming. Recently, there has been an increasing interest in social genetic effect (SGE) of pigs on stress-tolerance and behavior. The present study aimed to estimate genetic correlations among average daily gain (ADG), stayability (STAY), and number of piglets born alive at the first parity (NBA1) in Korean Yorkshire pigs, using the SGE model. The phenotypic records of ADG and reproductive traits of 33,120 and 11,654 pigs, respectively, were evaluated. The direct effect on ADG had a significantly negative genetic relationship with STAY, whereas the social effect on ADG had a neutral genetic relationship. In addition, the genetic correlation between the social effects on ADG and NBA1 tended to be positive, unlike the direct effects. The genetic correlation of the total effect on ADG with that of STAY was negative but non-significant, owing to the social effect. These results suggested that total genetic effect on growth in the SGE model might reduce the negative effect on sow longevity owing to the growth potential of pigs. We recommend including social effects as selection criteria in breeding programs to obtain satisfactory genetic changes in both growth and longevity.

Acute kidney injury (AKI) is a disorder that is manifested by a sudden decrease of renal function within several hours, and AKI remains a significant cause that can lead to increasing morbidity and mortality. Although AKI has been extensively studies in animal models, translating the results from animal studies into clinical use has not been successful due to various factors including basal etiology of kidney deficiency and comorbidities and the complexity of this pathology. As a golden parameter, measuring serum creatinine (SCr) and blood urea nitrogen (BUN) has been conventionally used for determining the renal function, however, these biomarkers has been regarded suboptimal to identify renal injuries in early stages. In this study, we attempted to screen other serum biomarkers in early AKI event using cynomolgus monkeys. Two male monkeys, aged 60 months, were subjected to ischemic injury by unilateral clamping of renal pedicles for forty five minutes and then subsequently reperfused; the unclamped kidney was regarded as non-injured controls. Compared with control kidneys, we have found that the concentration of several inflammatory proteins including MCP1, TGFα, GSTα, were higher in the renal vein of injured kidney compared with control side after 24 and 48 hours of AKI. However, changes of serum level of KIM-1, which is one of the most-widely studied marker in rodent studies, were not different after AKI. Our results provide an useful information while developing a novel marker in AKI.
