  • Rehmanniae Radix Preparata attributes good blood circulation and it has been used for the treatment of dizziness, men's sterility, excessive loss of blood and weakness. On the quality control of commercial Rehmanniae Radix Preparata, quantitative determination of 5-hydroxymethyl (5-HMF) using HPLC method has been conducted. Quantitative analysis of S-hydroxymethyl-2-furaldehyde (5-HMF) in commercial Rehmanniae Radix Preparata showed average of $0.136{\pm}0.057%$ in 14 samples collected throughout the regions of Korea.

  • A comprehensive study was conducted using PPSMV resistant (BSMR 736) and susceptible (ICP 8863) genotypes to develop a segregating population and understand the inheritance of PPSMV resistance. The observed segregation was comparable to 13 (susceptible): 3 (resistant). Hence, the inheritance was controlled by two genes, SV1 and SV2, with inhibitory gene interaction.

  • Animal experiments need numerous kinds of animal which are suitable for every research. About 300 mouse strains are developed up to the present, but they do not give satisfaction to every researchers. So we must build up the methods of breading animals which are newly developed and of maintenance of characteristics which were developed before. To maintain experimental animal is not only proceeding the generation but also increasing the animal populations, it needs geneticai control. Genetic factors which influence to reproduction are very important to maintain colony. These factors include lethal gene, chromosomal abberation, sterility gene, etc.. With the recent development of transgenic technology, scientists now can deliberately creat numerous specific animal models. To know how to manage the colony which has genetic defect on reproduction and transgenic mice is one of the key to study in vitro fertilization.

  • Co-segregation of male fertility with DNA markers selected by RAPD analysis as being potentially linked to the restorer gene (Rf) for Cytoplasmic male sterility (CMS) was analyzed using segregating F2 population. One RAPD marker directly linked to the Rf locus was identified. Amplification of OPT-02/570 using the STS primers generated a monomorphic band of each fertile plants randomly selected F2 progenies. From these results, this specific marker would be strongly linked to be restoring gene. The use of STS marker is effective in overcoming the reliability of the RAPD phenotype and improving their utility for MAS, co-dominant STS markers are especially very useful.

  • 1. Objectives I, the author, interviewed Taeyangin patients who were proved by clinical effect and also focused in bibliography to compare with Taeyangin patients case then I found out a several differences. 2. Methods I discoursed with comparing bibliography witch stated Taeyangin characteristics, such as ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$, ${\ulcorner}$Hwangje Nekyung${\lrcorner}$, ${\ulcorner}$Joongyi Chejilhak${\lrcorner}$, with interviewed 8 Taeyangin patients. 3. Results All of these 8 Taeyangin's men and women had very strong sharp-sighted. In characteristics and mental state, they usually were rather conservative than decisiveness, quick-tempered. In women case, they had average 1.78 children, no sterility, and didn't show a anger or sadness. The most of case ,showing a very sensitive reaction to food, were Nechoksojangbyung(內觸小腸病證). 4. Conclusions These results could be a important reference documents to classify Taeyangin in clinic.

  • A novel bioabsorbable suture material, poly(glycolide-caprolactone) (PGLCL) monofilament, was prepared by spinning of the PGLCL copolymer. The physical properties, strength retention, biocompatibility, and organism resolvability of the PGLCL monofilament were investigated. The results showed that the knot pull strength of the monofilament was higher than that stated in European Pharmacopoeia. The in vivo retention strength following implantation was 64%, 23%, 7%, and 0% after one, two, three, and four weeks, respectively. Mortality, clinical signs, validation, and sterility tests indicated that all items had passed. Organism resolvability tests showed that the PGLCL monofilament, as a suture, was absorbed within 91 days.

  • The purpose of this study was to analyze acupuncture treatment methods and acupoint used to treat infertility in the last decade. The data were retrieved from 2010.1 to 2021.8. using national and international electronic databases (PubMed, EMBASE, OASIS, NDSL, and KISS). "Infertility," "sterility," "acupuncture," "electroacupuncture," "bloodletting," "pharmacopuncture," were used as search terms. All studies were mainly concerned with acupuncture treatment of infertility, but the studies which were not related included; (1) infertility or acupuncture treatment; (2) animal studies; (3) review/meta/protocol or clinical study; comparative studies and case reports which were excluded from this review. Only clinical trials for acupuncture treatment of infertility were included in this review (n = 18). For infertility treatment studies using acupuncture, polycystic ovarian syndrome was the main cause of infertility, the most common acupoint used was CV4, CV3, CV6, SP6, BL23, and the treatment effect significantly improved in the group receiving acupuncture treatment compared with the control group, or the group taking Western medicine alone. In some studies, the group using acupuncture treatment did not show side effects. Acupuncture is an effective treatment for infertility.
