Embryo implantation is the crucial step for a successful pregnancy. Diverse factors, including adhesion molecules, growth factors, and cytokines are important for embryo implantation through improving endometrial receptivity. Benzoic acid (BA), a component of various plants, has been shown to have antifungal and antioxidant effects. However, the effect of BA on embryo implantation remains unknown. Here, we showed the contribution of BA for the enhancement of endometrial receptivity through the leukemia inhibitory factor (LIF)-dependent increase of integrin ${\alpha}V$, ${\beta}3$, and ${\beta}5$ expression. Furthermore, in vivo study using a mifepristone-induced implantation failure model showed that BA definitely improves the numbers of implantation embryos. Taken together, we suggest that BA has a novel function for embryo implantation through the up-regulation of LIF-mediated integrins, and may be a candidate for therapeutic medicine to increase the pregnancy rate.

Objectives: We studied for the adjustment of the patterns of 'The Diagnostic Tool for Climacteric and Postmenopausal Syndrome Pattern Identification (hereinafter CaPSPI)' (studyI) and the correlation between CaPSPI and Korean medicine doctors' diagnosis which was carried out without knowing the results of CaPSPI (studyII). Methods: The studyI followed the previous study method in 2018 (2018-3). The studyII was conducted from June 1, 2019 to July 10, 2020 with ◯◯ University Korean Medicine Hospital IRB's approval (2019-4). Doctors' diagnosis was conducted face-to-face with the subjects. Doctors' diagnosis was carried out based on the Kupperman's questionnaire, 'Diagnosis System of Oriental Medicine (hereinafter DSOM)' and four examinations (四診) records. The diagnosis was marked with 0 for 'no', 1 for 'somewhat', 2 for 'yes' and 3 for 'very yes'. The correlation between CaPSPI and the mean of doctors diagnostic scores were investigated statistically. Results: The studyI showed that heart-heat (心火) pattern was added. The Factor loading coefficient for heart-heat was 0.551 to 0.789, and the Cronbach's coefficient was 0.896. The studyII showed that the diagnosis (Kappa statistic) of two doctors showed statistically significant concordance (all eight patterns), with correlation of them were 0.3 or higher. And the correlation between the CaPSPI score and the mean of doctors' diagnostic score showed a statistically significant correlation, with liver qi depression (肝鬱) being the highest at 0.552 and dual deficiency of the heart-spleen (心脾兩虛) being the lowest at 0.301. Conclusions: Since the diagnosis results of CaPSPI showed a significant correlation with the diagnosis of Korean traditional medicine experts, it was believed that the CaPSPI results can be trusted and used for clinical purposes.

Objectives: This study was to evaluate the effect of Jaeumkanghwa-tang (JEKHT) on the propylthiouracil (PTU)-induced rat hypothyroidism. Methods: Six groups, each of 8 rats per group were used in the present study - intact vehicle control, PTU control, Levothyroxine ($LT_4$), JEKHT 500, 250 and 125 mg/kg treated groups. JEKHT were administered once a day for 42 days as an oral dose of 500, 250 and 125 mg/kg, and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. The changes on the body and organ weight, serum hormone and lipid profiles, liver and testis antioxidant defense factors were observed with histopathology of organs. Results were compared with $LT_4$ 0.5 mg/kg intraperitoneally treated rats in this experiment. Results: PTU treatment, marked decrease of body weight, increases of thyroid weight, decreases of liver, testis, epididymis and prostate weights, decreases of serum Tri-iodothyronine ($T_3$), and Thyroxine ($T_4$) level with increase of serum Thyroid-stimulating hormone (TSH) level, decreases of serum testosterone and dihydrotestosterone (DHT) level with increases of serum Follicular stimulating hormone (FSH) level, increases of serum High density lipoprotein (HDL), decrease of triglyceride content, increase of serum Aspartate aminotransferase (AST) level, decreases of liver and testis antioxidant defense factors were observed. In addition, marked hyperplasia of follicular cells with decreases of follicular colloid contents and diameters was additionally demonstrated with the decrease of hepatocyte numbers per unit area due to hypertrophy of hepatocytes related to lipid droplet depositions, increase of a/oligospermatic epididymal tubules with epididymal atrophic changes, seminiferous tubular atrophy with decrease of stage I~II seminiferous tubules in testis, prostate tubular atrophic changes at histopathological inspections. However, these PTU induced hypothyroidism and related hepatic and male reproductive organ damages were favorably and dose-dependently inhibited by treatment of JEKHT 500, 250 and 125 mg/kg, and JEKHT also effectively regulated the PTU-induced abnormal antioxidant defense factor changes in the both liver and testis. Conclusions: JEKHT 500, 250 and 125 mg/kg dose-dependently inhibited PTU-induced hypothyroidism and related liver and male reproductive organ damages in rats.

Objectives: The object of this study was to observe the in vitro antibacterial effects of Gagam-seopyoungjeon aqueous extracts (GGSYJ) against Gardnerella vaginalis and the possible synergic combination effects with clindamycin. Methods: Antibacterial activities against Gardnerella vaginalis of GGSYJ were detected using minimal inhibition concentration (MIC), and the effects on the bacterial growth curve were also monitored at MIC and MIC${\times}$2 levels. The combination effects of GGSYJ with clindamycin were observed by checkboard microtiter assay, and the effects of bacterial growth curve treated with GGSYJ MIC+clindamycin MIC, 1/2 MIC and 1/4 MIC, respectively. The effects on the bacterial invasion and intracellular killing of GGSYJ were also observed using human vaginal epithelial (VK2) and murine macrophage (Raw264.7) cells with combination effects with clindamycin after treatment of GGSYJ MIC+clindamycin 1/2 MIC, 1/4 MIC and 1/6 MIC, respectively. Results: The MIC of clindamycin and GGSYJ against Gardnerella vaginalis were detected as $0.012{\pm}0.006$ (0.004~0.016)${\mu}g/ml$ and $1.016{\pm}0.524$ (0.391~1.563) mg/ml, respectively. Clindamycin and GGSYJ were also showed marked dosage-dependent inhibition of bacterial growth, and significant decreases of viable cells were detected in clindamycin MIC+GGSYJ MIC and clindamycin 1/2 MIC+GGSYJ MIC treatment as compared with each of single clindamycin MIC and GGSYJ MIC treatments. And significant decreases of intraepithelial and intra-macrophage viable bacteria numbers were detected in clindamycin 1/2 MIC+GGSYJ 1/2 MIC and clindamycin 1/4 MIC+GGSYJ 1/2 MIC treatment as compared with each of single clindamycin GGSYJ 1/2 MIC treatments, respectively. Conclusions: GGSYJ showed slight antibacterial effects against Gardnerella vaginalis, but they showed dosage-dependent inhibitory effects on the bacterial growth and VK2 epithelial invasions of bacteria with favorable accelerating effects of intracellular killing activities of macrophages. In addition, combination of GGSYJ also increased the inhibitory effects of clindamycin on the epithelial invasions of Gardnerella vaginalis and intracellular killing activities of macrophages against Gardnerella vaginalis as 2-fold higher as compared with clindamycin single treatment, respectively. Therefore, we expected that the clinical dosages of clindamycin can be reduced as 1/2 levels as combination with GGSYJ.

Purpose: This study was designed to find out the anti-cancer effects of Samultang-Gami which was composed of Rehmanniae Radix(RR), Angelicae Gigantis Radix(AGR), Cnidii Rhizoma(CR), Paeoniae Radix(PR), Cortex Moutan Radicis(CMR), Hedyotis Diffusa(HD) and Caesalpinia Sappan on HeLa, HepG2 and AGS cells. Methods: Various cancer cell lines including HeLa, HepG2 and AGS cells, were used. In vitro anti-cancer effects were measured by MTT assay using cancer cell lines treated with various concentrations of 70% ethanol extract of Samultang-Gami. Expression of cell cycle arrest mediators including Bax, Bcl-2, p53 and DARP-1 proteins were measured by Western blot analysis. Results: 1. Samultang-Gami decreased the viability of HeLa and HepG cells in a dosedependent manner. 2. AGR, CMR, PR and HD decreased the viability of HeLa, HepG2 and AGS cells. 3. We could observe that the decreased Bax and Bcl-2 expression level and the increased PARP-1 expression level by Samultang-Gami extracts treated in HeLa cells. 4. We could observe that the decreased Bcl-2 expression level and the increased Bax, p53 and PARP-1 expression level by RR extracts treated in HeLa cells. and also could observe that the reduction of the protein level of Bcl-2, p53 and PARP-1 and the increase of the protein level of Bax by PR in HeLa cells. 5. We could observe that the increased p53 expression level, the decreased PARP-1's that and the unchanged Bax and Bcl-2's that by Samultang-Gami extracts treated in HepG2 cells. 6. We could observe that the reduced Bcl-2 expression level by each of RR extracts and PR extracts in HepG2 cells. 7. The treatment of Samultang-Gami in AGS cells didn't have any effect on the expression level of Bax, Bcl-2, p53 and PARP-1. 8. We could observe that the increased p53 and PARP-1 expression level by each of CR, RR and PR extracts in AGS cells. Conclusion: Taken together, we suggest that Samultang-Gami exhibits cytotoxic effects on HeLa, HepG2 and AGS cells, causing apoptosis. The results showed that Samultang-Gami may do so by regulating the expression of specific target molecules that promote efficient apoptotic cell death in a dose-dependent manner.

Objectives: Hwangryunhaedok-tang (HH) is a representative heat clearing multiherb prescription. We evaluated the protective effect of HH against heat stress exposure in mice. Methods: Six weeks old ICR mice were used for this study. After $43^{\circ}C$ heat stress for 15 minutes, we evaluated the changes of motor activity and c-fos expression level to determine the proper heat stress and evaluation time. The subjects were divided into 4 groups (1. control group, 2. heat stress group with normal saline, 3. heat stress group with administration of 100 mg/kg, and 4. heat stress group with administration of 1000 mg/kg). After oral administration of HH once a day for 3 days, 2, 3, 4 groups were exposed to $43^{\circ}C$ heat stress for 15 minutes. Then, we evaluated the motor activity for 120 minutes and analyzed the c-fos expression using western blot. We investigated the effect of HH and its ingredients on c-fos expressions after heat stress. The mice were administrated HH, Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex, and Gardeniae Fructus for 3 days. After one hour of last treatment, the mice were exposed to heat stress at $43^{\circ}C$ for 15 min. After two hours, the hypothalamus was dissociated and lysed to measure c-fos expression. Results: After oral administration of HH for 3 days, motor activity was recovered insignificantly. 100 mg/kg HH treatment reduced the c-fos expression after heat stress but insignificantly. Among the ingredients of HH, Coptidis Rhizoma and Scutellariae Radix treatment groups significantly reduced the c-fos after stress. Conclusions: These results show that Hwangryunhaedok-tang may be effective to reduce the heat stress response.

This study was undertaken to illustrate the uterotonic effect of Leonurus sibiricus. It was dissolved in sterile water and several different dosages were administered both in vitro and in vivo study. Rat uterine tissue for in vitro bioassay was obtained from estrous rat. From the low to high dosages of Leonurus sibiricus were tried and each uterine contraction was recorded and integrated. Anesthetized estrous rat for in vivo study was cannulated into the jugular vein for infusion of the compound. Another cannula with a balloon tipped and water filled was inserted into the uterus to measure uterine activity. While the uterine tissue did not respond to low dosage of compound, high dosage of compound stimulated the tissue to contract less than 1 minute with low amplitude. In vivo rat uterus showed a certain, consistent pattern of contractions which was initial relaxation and followed by prolonged and increased amplitude of contractions. It also caused a short breathing stop which might be due to acute acidosis.

유전자 재조합으로 제조한 사람 $interleukin-1{\beta}$ $(rhIL-1{\beta})$는 생쥐의 calvarial 골세포계에서 분리한 골아세포에 여러 가지 조절기능을 갖는 것으로 알려져 있다. 본 연구에서 $rhIL-1{\beta}$가 농도의존적으로 골세포에 영향을 주는지 해명하기 위하여 배양된 골아세포의 세포증식과 prostaglandin $E_2$합성 그리고 plasminogen activator활성에 대한 영향을 검토한 결과 이들을 촉진하였다. 그러나 비타민D에 따라 반응하는 골아세포의 특징으로 알려진 osteocalcin생합성과 alkaine phosphatase활성의 유도생성은 $rhIL-1{\beta}$에 의해 오히려 길항적이었다. 이러한 결과는 골세포대사의 병리학적인 조절과정에서 $IL-1{\beta}$가 골다공증의 병리학적 역할을 규명하는 새로운 결과이다. $IL-1{\beta}$에 의한 골흡수현상이 생쥐의 calvarial골세포에서 calcitonin처리로 크게 억제되어, 결과적으로 이러한 결과는 $IL-1{\beta}$에 의해 유발되는 골재흡수란 osteoclast에 의한다는 사실을 시사하였다. 한편, 한방에서 골다공증치료와 예방에 사용되는 대영전-자하거추출물의 기능을 해명하기 위하여, $IL-1{\beta}$-유발 $PGE_2$합성만을 특이적으로 저해하였다. 또한, 대영전-자하거 extract을 1시간 동안 여러 가지 농도로 전처리하고 다음으로 $PGE_2$-유도시약을 처리한 결과, $PGE_2$합성을 억제하였으며 동시에 $IL-1{\beta}$에 의해 유도된 plasminogen 의존적인 fibrinolysis을 억제하는 보호효과가 인정되었다. 한편, calcitonin처리가 $IL-1{\beta}$-촉진 골재흡수에 대한 저해활성을 보였으며 이러한 결과들은 calcitonin과 대영전-자하거 extract이 osteoclast매개성 골재흡수의 억제에 핵심적인 역할을 함을 시사하며 한방치료제로서의 근거를 제시하였다고 사료된다.
