The objective of this study was to determine the potential hazardous effects of sorting process by flowcytometry on the quality of boar spermatozoa by flowcytometer. Freshly collected boar semen was diluted and divided into two groups; control none sorted and sorted. Sperms in sorted group were processed with flowcytometer for cell sorting with $100\;{\mu}M$ nozzle under the 20 psi pressure. Measurements on each parameter were made at two time points, 0hr (right after sorting) and 24 hr post sorting. Although there was a tendency of lower viability in sorted group than none sorted control group, the percentage of live cells in control ($75.83{\pm}6.92\;&\;59.53{\pm}10.34$) was not significantly different from sorted ($59.70{\pm}7.37\;&\;43.97{\pm}3.76$) at both 0 and 24 hr post sorting. However, sorted sperm showed significantly lower mitochondrial function compared to the control at both 0 h ($79.37{\pm}3.22\;vs.\;63.50{\pm}10.05$) and 24 hr ($67.27{\pm}3.22$ vs. $46.97{\pm}5.37$) time points (p<0.007). Sperm DNA fragmentation rate was significantly lower in control ($22.0{\pm}7.04$) than that of sorted ($32.27{\pm}7.49$) at 24 hr time point (p<0.0002). Taken together, these data suggested thatsorting process by flowcytometer may have influenced sperm motility rather than viability. Also high speed sperm sorting by flowcytometer has significant effects on DNA fragmentation on elapsed time after sorting.

Background and Objective : Warfarin is the standard anticoagulation treatment for atrial fibrillation, venous thromboembolism (VTE), and mechanical heart valves. Close monitoring of the International Normalized Ratio (INR) is required due to the drug's very narrow therapeutic window. Many factors can affect INR levels. Drug and food interactions are frequently cited as causes of adverse events with warfarin. We discussed interactions between herbs and warfarin studied in this research. Methods : In this review, PubMed was used to search medical journals. Keywords "warfarin AND interaction" were applied. Results : 55 articles were included. The possibility of correlation between warfarin and single herbal medicines such as Salviae Miltiorrhizae Radix, Angelicae Gigantis Radix, Ginseng Radix Alba, Lycii Fructus, Ginkgo Folium, Menthae Herba, Trigonellae semen was suggested. Furthermore, some herbal compounds interacting with warfarin were reported. The conclusion of studies reporting the effect of herbal medicine on warfarin were controversial due to small size or quality of research. Conculsions : We suggest that we should prescribe therapeutic herbal medicines to patients using warfarin more carefully and do INR follow-up regularly.

Many bacteria colonized in the horse semen affect quality of the sperm and some may cause infection in the mare reproductive tract and infertility of susceptible mare. This study was initiated to determine the prevalence of bacteria in testes of Jeju horses by determining rRNA sequence. The samples were swabed from the testes of nine Jeju horses (aged from 8 to 12 months after birth). Bacteria isolated from testes were identified by 16S rDNA sequencing. 1.6-kbp PCR products for 16S rRNA coding region were obtained using the universal primers. The PCR products were further purified and sequenced. Maximum similar species were found by BLAST search in the GenBank DNA database. BLAST results showed that the sequences were similar to those of Acinetobacter sp (A. schindleri, A. ursingii)., Bacillus cereus, Corynebacterium glutamicum, Escherichia coli, Gamma proteobacterium, Micrococcus luteus, Pseudomonas mendocina, Shigella sonnei, Sphingomonas sp., Staphylococcus sp (S. cohnii, S. saprophyticus, S. xylosus)., and Stenotrophomonas maltophilia. DNA sequences for 16S rRNA is provided useful informations for species identification of pathogenic microorganisms for the reproductive organs in horses.

The cryopreservation has been extensively applied in many cells including spermatozoa (semen) during past several decades. Especially, the canine spermatozoa cryopreservation has contributed on generation of progeny of rare/genetically valuable dog breeds, genome resource banking and transportation of male germplasm at a distant place. However, severe and irreversible damages to the spermatozoa during cryopreservation procedures such as the thermal shock (cold shock), formation of intracellular ice crystals, osmotic shock, stress of cryoprotectants and generator of reactive oxygen species (ROS) have been addressed. According as a number of researches have been conducted to overcome these problems and to advance cryopreservation technique, several analytical methods have been employed to evaluate the quality of the fresh or cryopreserved canine spermatozoa in regards to the motility, morphology, integrity of membrane and DNA, mitochondrial activity, ROS generation, binding affinity to oocytes, in vitro fertilization potential and fertility potential by artificial insemination. Because the study designs with certain application of analytical methods are selective and varied depending on each experimental objective and laboratory condition, it is necessary to establish the normal reference data of the fresh or cryopreserved canine spermatozoa for each analytical method to monitor experimental procedure, to translate raw data and to discuss results. Here, we reviewed the recent articles to introduce various analytical methods for the canine spermatozoa as well as to establish the normal reference data for each analytical method in the fresh or cryopreserved canine spermatozoa, based on the results of the previous articles. We hope that this review contributes to the advancement of cryobiology in canine spermatozoa.

During storage, boar spermatozoa undergo several changes including diminished motility and viability and accumulated reactive oxygen species (ROS). In this study, we investigated the effects of green tea extract (GTE) supplementation in the Sui Dil extender on the sperm motility, viability, ROS and lipid peroxidation (LPO) of long-term preserved boar semen at $17^{\circ}C$. A total number of eight boars were used for this experiment. Pooled ejaculates were diluted to $20{\times}10^6sperm/ml$ in the Sui Dil extender containing 0 (control), 1, 10, 100 or 500 mg/l GTE and were preserved at $17^{\circ}C$ for 24, 72, 120 and 168 h, respectively. At each storage time, sperm motility and viability were estimated by microscopic examination and the fluorescent double stain $Fertilight^{(R)}$, respectively. Sperm ROS level and LPO were assessed using the 2', 7'-dichlorodihydrofluorescein diacetate ($H_2DCFDA$)/propidium iodide (PI) and C11-BODIPY581/591/PI with flow cytometry, respectively. Compared to that of the 500 mg group, there were higher sperm motility and viability in the 1, 10 and 100 mg GTE groups during the preservation from 24 to 168 h (p < 0.05). The ROS levels of the 10 and 100 mg groups during the 168 h preservation were lower than those of the 0, 1 and 500 mg groups (p < 0.05). There were no significant differences in LPO regardless of the preservation period or the GTE concentration. In conclusion, the optimal concentrations (10 and 100 mg/l) of GTE that led to lower ROS levels may be useful for liquid boar sperm preservation at $17^{\circ}C$ for a period of 168 h.

Objectives Edema occurs in various disorders, such as heart failure, nephrotic syndrome, renal failure, liver cirrhosis, and cancer. The excessive accumulation of interstitial fluid in limb tissue will often manifest with ankle and knee swelling and lowers patient's quality of life. But the conventional treatment includes restricting dietary sodium and using diuretics. The purpose of this study is about significant improvement of a patient with edema who had suffered from dependent gait accompanied by mild pain, after treatment by herbal medicine based on SCM(Sasang constitutional medicine). Methods The pattern identification of the patient was diagnosed with a superficial disease of Taeeumin. So after the admission, Gunyuljejo-tang was used, almost two times per day during 2 weeks. Also, we applied acupuncture routinely every day and western medicine as needed. We measured the circumferences of Lt. thigh and followed up the bioelectrical impedance analysis and checked the appearance of lower limb. Results and Conclusions The therapy was effective, and the circumferences, which was 59.69cm at onset time, decreased to 52.07cm almost same to the healthy side of her thigh. There was no more edematous sign on the body, either. This case showed that management of Taeeumin's healthy energy(呼散之氣, the energy of exhalation) could be effective in treating edema.

Bone marrow-derived cell (BMDC) therapy has numerous applications as potential biological cells for use in regenerative medicine. Here, we present an original case of endometrial atrophy associated with genital tuberculosis in a woman who achieved a live birth with BMDC. This 27-year-old woman came to our center with endometrial atrophy and primary infertility. She had a past history of genital tuberculosis and amenorrhea. Her husband's semen quality was normal. The patient was counseled for hysteroscopy due to thin endometrium and advised in vitro fertilization (IVF) with donor eggs in lieu of poor ovarian reserve. Several attempts of IVF with hormone replacement therapy (HRT) were made, but the desired thickness of the endometrium was not achieved. Uterine artery injection of BMDC through interventional radiology was given, followed by HRT for three months, which resulted in improved endometrium. This was subsequently followed by IVF with donor egg. The treatment resulted in the conception and delivery of a 3.1-kg baby boy through lower segment caesarean section with no antenatal, intranatal or postnatal complications. Recently, there has been massive interest in stem cells as a novel treatment method for regenerative medicine, and more specifically for the regeneration of human endometrium disorders like Asherman syndrome and thin endometrium, which was the reason behind using this strategy for treatment.

Objective: Hypothyroidism (HT) influences spermatogenesis and is associated with male infertility. Platelet-rich plasma (PRP), a biological product rich in growth factors, promotes tissue repair. In this study, the likely protective effects of PRP on testicular tissue damage in carbimazole (CBZ)-induced HT were evaluated. Methods: Forty male rats were divided into four groups. HT was induced by administering CBZ (1.35 mg/kg orally, for 45 days). Two doses of PRP (40 µL each, locally injected into the testis on days 15 and 30) were also given. After 45 days, blood samples were taken from the heart to measure triiodothyronine (T3), thyroxine (T4), and testosterone levels, and semen analysis was performed. For stereological assessment, the left testis was removed, fixed, embedded, sectioned, and stained with hematoxylin and eosin. The right testis was excised to evaluate antioxidant levels. Results: CBZ was demonstrated to induce HT, characterized by significant reductions in T3 and T4. HT was associated with decreased testicular weight, impaired sperm parameters, reduced testosterone concentration, diminished antioxidant activity, reduced volumes of testicular components, and lower total numbers of testicular cells of various types. When HT samples were treated with PRP, improvement was observed for all of these changes. This protective effect could be attributed to the growth factors present in PRP. Conclusion: PRP appears to prevent the structural changes in the testes and the deterioration in sperm quality caused by CBZ-induced HT. This protective effect is likely due to mitigation of oxidative damage and elevation of testosterone levels.

Objectives: This study was performed to review the research trends regarding the treatment of Postpartum Depression (P.P.D) in the Traditional Chinese Medicine (TCM). Methods: We searched articles in CNKI (China National Knowledge Infrastructure) from 2004 to 2013. Search key words were "产后抑郁症", "Postpartum Depression", and we selected 27 studies except for non-clinical studies, insufficient number of studies, unrelated studies and tests on animals. Results: We selected 27 articles with following results: 1) One study of Jadad Quality Assessment Scale score showed 3 points, 4 studies showed 2 points and 22 studies showed less than 1 point. Overall, the quality of the studies was low. 2) DSM - IV was frequently used as a diagnostic criteria and HAMD was mostly used as evaluation criteria. Diagnostic criteria and evaluation criteria were the same in HAMD and EPDS. 3) In TCM, there are various ways, such as herbal medicine, acupuncture, electro acupuncture, auricular acupuncture and/or massage to treat the postpartum depression. 4) The roots of Bupleurum falcatum Linne, Glycyrrhiza uralensis Fisch, Angelica gigas Nakai and Paeonia lactiflora Pall, the rhizome of Atractylodis macrocephala Koidz, the semen of Zizyphus jujuba Mill, the radix of Curcuma aromatica Salisb, the sclerotium of Poria cocos Wolf and the rhizomas of Cyperus rotundus L and of Cnidium officinale Makino are mainly used in the herbal medicine. BaekHoi (GV20) and Yindang (Ex-HN3) are mainly used in acupuncture points. 5) Most of the studies showed effective results. Some of the results were similar to those of the control groups which were cured by western medicine. Other results were better than those of control groups. Conclusions: Research on postpartum depression has been actively conducted in TCM and all studies showed effective results in the study group patients. Therefore, with this study, we hope to activate more clinical research on the treatment of patients in Korean traditional medicine.
