The intelligence is the capacity to recognize the things and implies the meaning of abstract thought, learning and adaptability to the circumstance. Recently, as the promotion of learning ablility and memory attracts many people's attention, many studies of this have been accomplished but the pharmacological methods could not promote the intelligence and memory. In oriental medical theory, the human body is composed of four elements - essence, energy, sprit, blood and among these elements, sprit is considered as the concept of vital energy and mind. Especially, from the Jang-Fu physiological point of view, the memory is closly related with the heart and kidney In oriental medicine, some experiments on animal and literature studies on the subject of memory promotion have done. But because of difference in memory mechanism between man and animal, it is not in reason to apply the result of experiment on animal to human. Therefore I have methodological study of memory promotion to set up the concept of oriental medicine and experimental theory about this and can obtain such conclusion. 1. The oriental medical therapy for memory promotion is following. nourishing the heart and blood, regulating the function of spleen, relieving the mental stress, reinforcing the heart and kidney, invigorating and enriching the blood. 2. The insufficient intelligence in a child is considered to not be full and in an old man, it is considered to decline by degrees. 3. It is needed to molecular biological study of neurotransmitter after the using of oriental medical therapy. 4. It is possible to study using the genetic mutation or observing the collateral of brain nerve cell.

Objectives : The aim of this study was to conduct a scoping review focusing on acupuncture points information applied in experimental studies using electroacupuncture for stroke. Methods : First, we set the research question of this study to identify which acupuncture points were studied for various symptoms of post-stroke sequelae in clinical and animal experiments. For this purpose, among the records searched through EMBASE, experimental studies including acupuncture points used in electroacupuncture treatment for stroke were selected as inclusion criteria for this study. The acupoints information used in each experiment was extracted from the included studies according to the type of study design and symptoms of stroke sequelae, and quantitative analysis was performed. Results : A total of 973 studies using acupuncture treatment, of which 429 papers including electroacupuncture were analyzed. Most of the animal experiments were conducted on general conditions instead of specific symptoms of stroke, and in clinical studies, electroacupuncture studies were conducted on symptoms such as hemiplegia and spasticity, cognitive and mental problems, dysphagia, shoulder problems, and depression that occur after stroke. Acupuncture points such as GV20, ST36, LI11, and LI4 were mainly used regardless of stroke symptoms. Except for these acupuncture points, GV26, GV14, GV16, and GV24 were frequently used in animal experiments, and TE5, LI15, LI10, and LR3 were widely used in clinical studies. Conclusions : Although this study extracted and analyzed only the frequent acupuncture points in the electroacupuncture study for stroke. However, in the future, it is necessary to be able to secure the evidence for acupuncture treatment elements through comparative studies between different acupuncture points or other elements constituting electroacupuncture.

This study determined the concentrations of micro-minerals in pastures, in feed supplements and in grazing, reproducing ewes, at different times during the year, at three farms in Northern China. Samples were collected 5 to 8 times during the year and analysed for selenium, copper, iron, molybdenum and zinc. On two farms selenium concentrations in both pastures and animal tissues were low for part of the year. The lowest concentrations in pasture (< $30{\mu}g/kg$ DM) and liver (< $100{\mu}g/kg$ wet weight) indicated that productivity of the sheep may be reduced by a deficiency of this element. On one farm copper concentrations in the lever were in the liver were in the deficient range (< $5{\mu}g/kg$ wet weight) for part of the year. It is likely that this is a result of high intakes of iron from pasture (up to 4.5 g Fe/kg DM) and soil, as indicated by high concentrations of iron in faeces (up to 7 g Fe/kg DM). Molybdenum intake is unlikely to have had much influence on copper absorption because pasture concentrations of this element were not unusually high (1 to 5 mg/kg DM). Zinc in pastures on two farms was below 10 mg/kg DM for part of the year. On one of these farms, the concentration of zinc in faeces was below 30 mg/kg DM throughout the year and this is consistent with zinc intakes of 7 to 15 mg/kg. Despite these low intakes, the concentratons of zinc in plasma were consistently above deficient levels. No clinical signs of deficiencies of any of the elements studied were observed.

Purpose: In EU, the animal welfare regulations are strengthening. Also, in Korea, for strengthening of animal protection laws, animal welfare farm certification scheme is being prepared to enforce. To get the certification of animal welfare farm, especially for sows, individual specific feeding in sow group is necessary in accordance with the animal welfare regulation. Also, liquid feeding is reported to be more effective for farrowing as well as dry sow. Therefore, in this study, a electronic liquid sow feeder using RFID which could be fed to farrowing sow simultaneously is developed. Methods : We manufactured a prototype of appropriate elements which were evaluated in the preliminary test for selecting RFID tag, supply pump, mixing type, etc. With the prototype, the performance test for liquid feeding gilt was done in group raising training barn. Results : The performance test result shows the C.V.(coefficient of variation) of liquid mixing and feeding is 0.77~1.97% and 2.4~5.3%, respectively, which means the system could feed sows uniformly. The feeding time of pneumatically activated ball valve is 2 seconds per 0.9 kg of liquid feed. The eating time for gilt were 65 seconds in average. Conclusions : The prototype could feed sow uniformly, and deliver the liquid feed 9 times for a sow continuously. Also, total eating time for a sow was 18 minutes in one visit to the prototype of feeding station.

Glutamate is a putative excitatory neurotransmitter in the central nervous system. The present study utilizing monoclonal antibodies against fixative-modified glutamate analyzed the distribution of glutamate-immunoreactive neuronal elements in the dog basilar pons. The glutamatergic neurons were present throughout the rostrocaudal extent of the basilar pons, predominantly to the medial and ventral subdivisions. Labelled cells were relatively sparse in the midline region of the medial nucleus and most lateral area of the lateral nucleus. The majority of glutamate-immunoreactive neuronal somata in the basilar pons was multipolar-shaped, and the size was in the range of 15-25 ${\mu}$m in diameter. Glutamate-immunoreactive axons and terminals were also observed at specific regions of the basilar pons. These observations provide evidence that this excitatory neural element functions in a multisynaptic pathway involving glutamatergic afferents to the basilar pons, pontocerebellar projection neurons, and the granule cells of the cerebellar cortex.

The reproduction of animals is a way to maintain their species and demands a large amount of energy. The golden hamsters are seasonal breeders whose reproductive activities are regulated by photoperiod (length of day time in a day). The photic information received is transported to the pineal gland via many steps. Melatonin produced by the pineal gland affects the reproductive neuroendocrine system to manage reproductive activities. The major regulator neurons, secreting gonadotropin-releasing hormone, integrate all kinds of information to govern the reproductive frame hypothalamuspituitary-gonad axis. The elements impinging on the neurons are recently outspread. Thus the present review is to briefly survey the elements discovered newly and subjected to the active research realm and their correlations, focusing on the regulation of reproduction in mainly male golden hamsters as a representative animal.

This review addresses the escalating challenge posed by antibiotic resistance, highlighting its profound impact on global public health, including increased mortality rates and healthcare expenditures. The review focuses on the need to adopt the One Health approach to effectively manage antibiotic usage across human, animal, and environmental domains. Antimicrobial stewardship programs (ASPs) are considered as comprehensive strategies that encompass both core and supplementary initiatives aimed at enhancing prudent antibiotic use. The 2021 "Guidelines on Implementing ASP in Korea" introduced such strategies, with a strong emphasis on fostering multidisciplinary and collaborative efforts. Furthermore, the "Core Elements for Implementing ASPs in Korean General Hospitals," established in 2022, provide a structured framework for ASPs, delineating leadership responsibilities, the composition of interdisciplinary ASP teams, a range of interventions, and continuous monitoring and reporting mechanisms. In addition, this review examines patient-centric campaigns such as "Speak Up, Get Smart" and emphasizes the pivotal role of a multidisciplinary approach and international cooperation in addressing the multifaceted challenges associated with antibiotic resistance.

Porcine endogenous retroviruses (PERVs) in the pig genome represent a potential risk of infection in pig-to-human transplantation and are transmitted vertically. The solitary long terminal repeat (LTR) elements of the PERVs affect the replication properties of the individual viruses via their repeat sequences and by encoding a set of specific transcription factors. We examined the promoter activities of solitary LTR elements belonging to the PERV-A and -B families of the Korean domestic pig (KDP) using luciferase reporters. Three of the LTR structures (of PERV-A5-KDP, PERV-A7-KDP, PERV-A8-KDP) had different promoter activities in human HCT116 cells and monkey Cos7 cells, and potential negatively and positively acting regions affecting transcription were identified by deletion analysis. These data suggest that specific sequences in the U3 region of a given LTR element can affect the activities of promoter or enhancer elements in the PERV.

A novel TEM resonator coil was developed for the imaging of small animals. The functional elements of the TEM resonator were 8 inner conductors, distributed in a cylindrical pattern and connected at the ends with capacitors to the cylindrical outer shield. The TEM resonator coil with cavity elements was robust to the surrounding influences due to the self-shielding structure. The TEM resonator coil with high Q factor could provide high quality MR images at 3.0T MRI system. Also, the TEM resonator coil has an advantage for a fine tune with length adjustment of each cavity elements. Thus, The TEM resonator coil at 3.0T, even higher field could be used in the research studies.

Novel and specific recognition elements are of central importance in the development of a pathogen detection method. Here, we describe a simple method for identifying the cell-wall binding domain (CBD) from a sequenced bacterial genome employing homology search for phage lysin genes. A putative CBD (CPF369_CBD) was identified from a genome of Clostridium perfringens type strain ATCC 13124, and its function was studied with the CBD-GFP fusion protein recombinantly expressed in Escherichia coli. Fluorescence microscopy showed the specific binding of the fusion protein to C. perfringens cells, which demonstrates the potential of this method for the identification of novel bioprobes for specific detection of pathogenic bacteria.
