  • Interferon induced transmembrane protein-1 (Ifitm-1) has been reported to have an important role in primordial germ cell formation, and it has expressed in female reproductive organ. In the present study, Ifitm-1 gene expression was identified in testes and all part of epididymis using western immunoblot and immunohistochemistry. Interestingly, Ifitm-1 expression was observed on the head of spermatozoa. To investigate the role of Ifitm-1 gene expression in behavior of spermatozoa after acrosome reaction, fresh sperm was incubated with calcium ionophore to induce acrosome reaction, whereas the expression of Ifitm-1 was not altered after the acrosome reaction. Then to identify the effect of Ifitm-1 in sperm motility and other seminal parameters, different concentration of Ifitm-1 antibody was incubated with spermatozoa, and seminal parameters were assessed using computer-assisted semen analysis (CASA). Interestingly, motility, progressive, and VAP were increased in the sperm with Ifitm-1 antibody treated compared to rabbit serum, however other parameters such as straightness were not changed. In order to identify the functional significance of Ifitm-1 in fertilization, capacitated spermatozoa were pre-incubated with anti-Ifitm-1 antibody and subsequently examined the ability to adhere to mouse oocytes. However, any defection or alteration in sperm-egg fusion was not found, Ifitm-1 antibody treated or non-treated spermatozoa showed a normal penetration. Although the precise role of Ifitm-1 in sperm motility and following fertilization need to be elucidated, this study suggests that the activation of Ifitm-1 on the sperm may enhance the motility of spermatozoa in mice.

  • Objective : Myeongganbo (MGB) composited with Hovenia Semen, Puerariae Radix and Dioscoreae Rhizoma is the prescription for protection of liver function. The purpose of this study was to investigate the effects of MGB extract against acetaminophen (APAP)-induced liver injury in mice. Methods : MGB extract was prepared by extracting with hot distilled water. The extract was freeze-dried following filtration through vacuum distillation system. Mice fasted for overnight were orally administrated with or without MGB extract of different doses (25-200 mg/kg/day). After 30 min, APAP was orally applied with a single dose (400 mg/kg). The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured in plasmas of mice. Glutathione (GSH), glutathione peroxidase GSH-px), cyclooxygenase-2 (COX-2) activity and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level were investigated in liver homogenates. Liver sections were stained with haematoxylin & eosin, anti-TNF-${\alpha}$ and anti-mouse COX-2 antibodies. Results : APAP treatment remarkably increased AST and ALT activities in plasma but inhibited GSH and GSH-px levels in liver homogenates. Also, liver injury was significantly accelerated by APAP treatment. Furthermore, APAP remarkably elevated COX-2 activity and TNF-${\alpha}$ levels in liver homogenates. However, administration of MGB extract was able to counteract these effects. Histological studies provided supportive evidence for biochemical and molecular analysis Conclusions : These results suggest that MGB extract has potent hepatoprotective effect against APAP-induced liver injury, these properties may contribute to liver disease care.

  • To establish the normal fertile range in the results of the sperm zona-free hamster ova penetration assay (SPA) in Korean male, SPA using the low temperature ($4^{\circ}C$) capacitation in TEST-yolk buffer (TYB) was performed in 67 fertile and 26 infertile men. Sperm parameters in routine semen analysis were also checked and compared with the results of SPA. Sperm concentration, motility and motility index (MI) were significantly higher in fertile group compared with infertile group: $96.0{\pm}46.6$ vs $43.6{\pm}31.9{\times}10^6/ml$, $65.5{\pm}14.8%$ vs $45.8{\pm}23.6%$ and $46.31{\pm}13.29$ vs 27.40{\pm}17.98$, respectively. In fertile group, the hamster ova penetration rate (PR) was $98.5{\pm}5.0%$ (80%-100%), and the penetration index (mean penetrations per ovum, PI) was $9.59{\pm}6.35$(3.1-29.0). All the fertile men showed PI>3.0. In infertile group, PR was $24.6{\pm}24.8%$ (0%-70%), and PI was $0.40{\pm}0.42$ (0-1.3). Both PR and PI were significantly lower in infertile group. There was a significant correlation beween PI and sperm motility or MI, respectively, in fertile group whereas there was no correlation in infertile group. These data suggest that SPA using the low temperature capacitation in TYB can be a valuable diagnostic tool for the assessment of male fertility in vitro and provide an important supplement to the traditional tests of sperm quality.

  • Objectives To check marker content for appropriate quality control of Woohwangchungsimwon sterilized to ensure microbiological safety and to observe antioxidant activity for any changes in efficacy. Methods To measure any effects of sterilization on the effective compounds, 8 ingredients of Woohwangchungsimwon were screened for any changes in marker content using HPLC-DAD. Using the colorimetric method on the microplate reader any changes in total phenolic compound and flavonoid levels were observed. Antioxidant activity was measured using the DPPH, ABTS, and FRAP. Results Of the ingredients of Woohwangchungsimwon, 8 were subject to quantitative analysis before and after sterilization. 21.6 mg and 1.93 mg of Glycyrrhizin was found in Glycyrrhiza uralensis Fischer pre and post sterilization, respectively. Decursin found in Angelica gigas Nakai increased from 0.16 mg to 0.29 mg after sterilization. Bilirubin found in Gallstone of Bostaurusvar. domesticus increased from 0.24 mg to 0.33 mg. Cinnamic acid found in Cinnamomum cassia Blume increased from 0.02 mg to 0.05 mg. Ginsenoside Rb1 found in Panax ginseng C. A. Meyer decreased from 0.02 mg to 0.14 mg. Paeoniflorin found in Paeonia lactiflora Pallas increased from 1.05 mg to 1.13 mg. Amygdalin found in Armeniacae Amarum Semen increased from 2.68 mg to 2.83 mg. L-muscone found in Musk increased from 0.63 mg to 0.76 mg. As for total phenolic compound and total flavonoid content, there was a 1.22 and 4.15-fold increase. DPPH and ABTS increased by 20.45% and 20.69%, respectively. FRAP activity was 2.78 times more active post stabilization. Conclusions This study confirmed that high temperature high pressure steam sterilization, a method used to ensure microbiological safety of Woohwangchungsimwon, does not affect marker content; in other words, does not affect quality of the Woohwangchungsimwon. It could also be seen that total phenolic compound and flavonoid content increased after sterilization. An antioxidant activity test showed that there was significantly increased activity of antioxidants.

  • Postpubertal mumps may result in ochitis and permanent testicular atrophy may develop following infection. This present study was initiated to evaluate the preventive effect of interferon-${\alpha}2B$ on infertilty after mumps orchitis. There were 21 patients with mumps orchitis between May 1990 and June 1997. Patients were randomly distributed into 2 groups: group 1 patients (n=13) maintained therapy with interferon-${\alpha}2B$ ($3{\times}10^6$ IU per day) and group 2 were managed by conservatively. All of the patients were evaluated with testis size measurement, mumps virus titer, hormone level, and if possible semen analysis. For group 1 patients symptoms disappeared within 2 to 3 days and the volume of testis returned to normal within 11 days and testis atrophy was not observed in all patients in follow up. But asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). For group 2 patients symptoms disappeared within 5 to 6 days and the volume of testis returned to normal within 10 days and testis atrophy was observed in 3 patients (unilateral 2, bilateral 1) in floow up. Asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). Sperm count and morphology were recovered all the recover in group 1, 4 patients had persistent reduced sperm count and morphology in group 2, respectively. These observations suggest that systemic interferon-${\alpha}2B$ treatment is highly effective in preventing infertilty as well as testicular atrophy after mumps orchitis.

  • The objective of this study was to evaluate the efficiency of sperm cryosurvival in boar sperm separated by Percoll containing antioxidant enzymes. The boar semen was collected into a pre-warmed ($37^{\circ}C$) thermos bottle by gloved-hand method and was separated by 65% Percoll with superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) before freezing. The frozen sperm was thawed at $38.5^{\circ}C$ for 45 sec in water-bath for sperm characteristic analysis. The sperm were estimated with SYBR14/PI double staining for viability, FITC-PNA/PI double staining for acrosome reaction, Rhodamine123/PI double staining for mitochondrial integrity and were analyzed using flow cytometry. In results, sperm viability, acrosome reaction and mitochondrial integrity were improved in separated sperm groups compared with unseparated sperm by Percoll (UP) group. Especially, viability was significantly higher in sperm separated by Percoll containing 400 IU CAT group compared with other groups (P<0.05). And acrosome reaction was decreased in sperm separated by Percoll with 300 IU SOD, 400 IU CAT and 0.5 mM GSH groups compared with other groups, however, there were no significantly difference mitochondrial integrity among sperm separated by Percoll with antioxidant enzymes. In conclusion, we suggest that use of Percoll containing antioxidant enzymes for sperm separation will be beneficial for sperm cryopreservation in pigs.

  • Hyperlipidemia is one of the risk factors for coronary artery disease. Despite of epidemiological evidence that tea consumption is associated with the reduced risk of coronary heart disease, experimental studies designed to show that drinking tea affects blood lipid concentration or oxidative stress have been unsuccessful. The purpose of this study was to investigate whether functional tea (three servings/day) supplement with medical nutrition therapy (MNT) lead to a beneficial outcomes in mildly hyperlipidemic adults. From February to October, 2003, the 43 hyperlipidemic (23 men, 20 women) subjects (total cholesterol$\geq$200 mg/dL or triglyceride$\geq$150 mg/dL) admitted to K Medical Center were studied. Subjects were randomly divided into 3 groups; placebo tea (PT), half dose of functional tea (HFT), full dose of functional tea (FFT). During 12 weeks of study period, the subjects were given placebo or functional tea daily with MNT. Anthropometric measurements, blood chemical analysis including lipid levels, total superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels, and dietary assessment were carried out at the beginning and end of experiment. The effects of functional tea were compared with the placebo in randomized clinical trial study. The placebo was prepared to match with the functional tea in color and taste. After the 12 weeks of MNT, the subjects had regular and balanced meal pattern. Consumption of foods high in cholesterol and saturated fat, salty foods, fried foods, and instant foods decreased significantly in all three groups (p<0.05). Intake of energy and cholesterol also decreased (p<0.05). Drinking three servings per day (390 mL/day) of functional tea significantly reduced the levels of blood triglyceride (HFT, 42.5%; FFT, 29.4%), total cholesterol (HFT, 8.5%; FFT, 13.7%), and atherogenic index (HFT, 14.6%; FFT, 21.7%). Whereas no changes were found in the LDL-, HDL-cholesterollevels, and LDL/HDL ratio. Plasma homocysteine (Hcy) concentration decreased significantly (p<0.05) in functional tea groups (HFT, 14.9%; FFT, 14.1%). SOD increased significantly (p<0.05) in HFT (8.3%). GSH-Px increased significantly (p<0.05) in FFT (12.8%). In conclusion, the MNT improved the dietary habits, in addition, functional tea supplement decreased blood lipid levels and Hcy, and increased SOD and GSH-Px levels. These results indicate that functional tea consumption may decrease the risk of cardiovascular disease via improving blood lipid levels and antioxidant status.

  • Objectives: This review investigated the research on warm herbal foot bath therapy (WHFT) for insomnia. Methods: A search was conducted on the China National Knowledge Infrastructure (CNKI) database to collect relevant studies published up to August 29, 2023. Randomized controlled trials (RCTs) comparing WHFT and sleeping pills in patients with insomnia were included. The methodological quality of the included studies was assessed using the Cochrane risk-of-bias assessment tool. The results of the meta-analysis were presented as risk ratios (RRs) or mean differences (MDs) and their 95% confidence intervals (CIs). Results: A total of 11 RCTs were included. WHFT as monotherapy resulted in a significantly higher total effective rate (TER) (RR, 1.25; 95% CI, 1.15 to 1.36; I2=25%) and an improved Pittsburgh Sleep Quality Index (PSQI) global sore (MD, -3.10; 95% CI, -4.24 to -1.95; I2=73%) compared to benzodiazepines. Additionally, WHFT as a combined therapy with benzodiazepines resulted in a significantly higher TER (RR, 1.15; 95% CI, 1.04 to 1.27; I2=0%) and an improved PSQI global score (MD, -2.23; 95% CI, -4.09 to -0.38; I2=80%) compared to benzodiazepines alone. In network analysis visualizing the components of HWFT, four clusters were discovered, and Polygoni Multiflori Ramuls and Ziziphi Spinosae Semen were the key herbs used in WHFT. Overall, the methodological quality of the included studies was poor. Conclusions: There was limited evidence that WHFT as a monotherapy or combined therapy was effective in improving insomnia. The findings can be used as basic data for future WHFT research in South Korea.
