The following experiments were designed to examine the effect of serum of spayed dogs on superovulation response in mice and rats. In Experiment 1, female mice at diestrus (n=30) were divided into three equal groups and superovulated with either administration of 5 IU pregnant mare serum gonadotropin (PMSG) or recombinant follicle stimulating hormone (rFSH) (reducing dose from 2.5 to 0.5 IU) and 5 IU human chorionic gonadotropin (hCG) administered 48h later. Serum of spayed dogs was administered intraperitoneally at a reduced dose from 0.1 to 0.025 mL in a 48 h period. In Experiment 2, female rats (n=30) at diestrus stage were divided into three equal groups. Superovulation was induced using either 30 IU PMSG, or a dose reduced from 5 to 1 IU rFSH and 25 IU hCG administered 48h later. Serum of spayed dogs was administered in a reduced dose from 0.6 to 0.1 mL in a 48 hour period. Female mice and rats were mated 24 h following hCG administration. On day 14 after mating, animals were euthanized and ovarian sections were fixed for histopathological evaluation and corpus luteum (CL) counting. No significant difference observed in mean (${\pm}SEM$) number of CLs between the PMSG group and the mice that received serum of spayed dog ($10.4{\pm}1.3$ vs $9.2{\pm}1.0$). Mean (${\pm}SEM$) number of CLs tended to be lower in rats that received serum of spayed dog than those of rats which received either PMSG or rFSH ($15.1{\pm}1.9$ vs $23.6{\pm}3.1$ and $23.1{\pm}2.9$, P=0.06, respectively). In conclusion, serum of spayed dogs is able to induce a superovulatory response in mice and rats.

Muscle atrophy, characterized by a reduced number and size of myofibers, occurs due to immobilization, aging, and several chronic diseases. Leonurus japonicus, belonging to the Labiatae family, is widely used as a traditional medicine in Korea, China, and Japan. Previous studies have reported that L. japonicus has various physiological activities, such as anti-bacteria, anti-cancer, and liver protection. Leonurine, which is a major bioactive in L. japonicas, is known to possess biological effects including anti-inflammation, anti-fibrosis, anti-angiogenesis, and anti-diabetes. However, the preventive effects of L. japonicas and leonurine on muscle have not been reported. The current study aimed to determine the inhibitory effects of standardized L. japonicus extract (LJE) and leonurine on muscle atrophy by clarifying their underlying molecular mechanisms in tumor necrosis factor-alpha (TNF-α)-stimulated L6 myotubes. LJE and leonurine stimulated the phosphatidylinositol 3-kinase/Akt pathway that was reduced by TNF-α treatment. LJE and leonurine not only increased the mammalian target of rapamycin pathway for protein anabolism but also decreased the mRNA expression of E3 ubiquitin ligases by blocking the translocation of Forkhead box O, which is closely linked with proteolysis. Additionally, LJE and leonurine alleviated inflammatory responses by downregulating TNF-α and interleukin-6 mRNA expression and reducing the protein expression of nuclear factor-kappa B, a major transcriptional factor of proinflammatory cytokines. Collectively, LJE and leonurine have potential as therapeutic candidates for inhibiting the development of skeletal muscle atrophy by activating the PI3K/Akt pathway and reducing inflammatory responses.

Clonorchis sinensis is a food-borne trematode that infects more than 15 million people. The liver fluke causes clonorchiasis and chronical cholangitis, and promotes cholangiocarcinoma. The underlying molecular pathogenesis occurring in the bile duct by the infection is little known. In this study, transcriptome profile in the bile ducts infected with C. sinensis were analyzed using microarray methods. Differentially expressed genes (DEGs) were 1,563 and 1,457 at 2 and 4 weeks after infection. Majority of the DEGs were temporally dysregulated at 2 weeks, but 519 DEGs showed monotonically changing expression patterns that formed seven distinct expression profiles. Protein-protein interaction (PPI) analysis of the DEG products revealed 5 sub-networks and 10 key hub proteins while weighted co-expression network analysis (WGCNA)-derived gene-gene interaction exhibited 16 co-expression modules and 13 key hub genes. The DEGs were significantly enriched in 16 Kyoto Encyclopedia of Genes and Genomes pathways, which were related to original systems, cellular process, environmental information processing, and human diseases. This study uncovered a global picture of gene expression profiles in the bile ducts infected with C. sinensis, and provided a set of potent predictive biomarkers for early diagnosis of clonorchiasis.

Background: Nonalcoholic steatohepatitis (NASH) is one of the main chronic liver diseases. NASH is identified by lipid accumulation, inflammation, and fibrosis. Jinan Red Ginseng (JRG) and licorice have been widely used because of their anti-inflammatory and hepatoprotective effects. Hence, this study assessed JRG and licorice extract mixtures' effects on NASH progression. Methods: Palmitic acid (PA) and the western diet (WD) plus, high glucose-fructose water were used to induce in vitro and in vivo NASH. Mice were orally administered with JRG-single (JRG-S) and JRG-mixtures (JRG-M; JRG-S + licorice) at 0, 50, 100, 200 or 400 mg/kg/day once a day during the last half-period of diet feeding. Results: JRG-S and JRG-M reduced NASH-related pathologies in WD-fed mice. JRG-S and JRG-M consistently decreased the mRNA level of genes related with inflammation, fibrosis, and lipid metabolism. The treatment of JRG-S and JRG-M also diminished the SREBP-1c protein levels and the p-AMPK/AMPK ratio. The FAS protein levels were decreased by JRG-M treatment both in vivo and in vitro but not JRG-S. Conclusion: JRG-M effectively reduced lipogenesis by modulating AMPK downstream signaling. Our findings suggest that this mixture can be used as a prophylactic or therapeutic alternative for the remedy of NASH.

Alagille syndrome (AGS) is a rare autosomal dominant inherited disorder, with major clinical manifestations of bile duct paucity, cholestasis, cardiovascular anomaly, ophthalmic abnormalities, butterfly vertebrae, and dysmorphic facial appearance. It is caused by heterozygous mutations in JAG1 or NOTCH of the Notch signaling pathway presenting with variable phenotypic penetrance and involving multiple organ systems. The following case report describes a unique case of a 16-year-old female with AGS who presented with the primary complaint of renovascular hypertension. She had a medical history of ventricular septal defect and polycystic ovary syndrome. The patient had a dysmorphic facial appearance including frontal bossing, bulbous tip of the nose, a pointed chin with prognathism, and deeply set eyes with mild hypertelorism. Stenoocclusive changes of both renal arteries, celiac artery, lower part of the abdominal aorta, and left intracranial artery, along with absence of the left internal carotid artery were found on examination. Whole exome sequencing was performed and revealed a pathologic mutation of JAG1, leading to the diagnosis of AGS. Reverse phenotyping detected butterfly vertebrae and normal structure and function of the liver and gallbladder. While the representative symptom of AGS in most scenarios is a hepatic problem, in this case, the presenting clinical features were the vascular anomalies. Clinical manifestations of AGS are diverse, and this case demonstrates that renovascular hypertension might be in some cases a presenting symptom of AGS.

Noni has been used for medicinal purposes for more than 2,000 years in South Pacific Polynesia, China and India, and has been heavily ingested as an extract for its excellent antioxidant and anti-inflammatory effects. However, a recent study found that the noni extract causes digestive disorders, kidney problems, and liver diseases, which made it necessary to use it for other purposes than as an extract. In this study, we want to evaluate the potential of noni as an anti-oxidant, anti-inflammatory and anti-wrinkling agent. Methods: Noni was freeze-dried, extracted in water, and concentrated. Skin cells were treated with the noni extract for 24 hrs and then were exposed to UVB (55 mJ/cm²). After 48 hrs of incubation, pro-inflammatory cytokine, elastase, MMP-1 and type-1 procollagen levels were measured by ELISA. Results: To find out the antioxidant effect of the noni extract, the DPPH and ABTS radical scavenging activity experiments were conducted and the noni extract showed 97.0 % and 92.0 % antioxidant efficacy at 200 ㎍/mL respectively. The noni extract (50 and 100 ㎍/mL) decreased IL-6 and TNF-α in RAW 264.7 cells induced by LPS in a concentration-dependent manner. In the RT-PCR experiment involving NO production, the noni extract (50 and 100 ㎍/mL) inhibited NO production by strongly inhibiting iNOS mRNA expression, and also inhibited the elevation of MMP-1 and elastases caused by UVB irradiation by 25.0 % and 7.0 % respectively. In addition, type-1 procollagen was elevated by 20.0 % by the noni extract treatment in HaCaT cells. Conclusion: The noni extract has photoprotective ability by reducing proinflammatory mediators, elastase and MMP-1 production, and elevation of collagen synthesis. Our findings suggest that the noni extract might be a good natural substance to protect against UVB-induced premature skin aging.

Objectives : To study the characteristics and meaning of the division pharmaceutical method in the Donguibogam through analysis of formulas that apply such method. Methods : Each formula applying the division method within the Donguibogam was analyzed Results & Conclusions : In the Donguibogam, medicinals to which the division pharmaceutical method was applied were baizhu[白朮], cangzhu[蒼朮], zhiqiao[枳殼], wuzhuyu[吳茱萸], xiangfuzi[香附子], chuanlianzi[川練子], huangbo[黃柏], etc. Formulas where this method was used were few, while the four methods that were used, together with the Center represents the principle of the five phases. The formulas that applied the division method usually did not adopt the tablet or decoction form, which means they were meant to treat slowly, treating deficiency or stagnation diseases due to problems in the middle-lower body such as the Spleen, Liver and Kidney. It could be said that compared to other more common formulas, this was a unique method. The division pharmaceutical method allows for usage of a wider variety of processing methods compared to single ingredient formulas, while there is lower chance of interference among the different types of processing. Another benefit is that the properties of the main medicinal ingredient could be preserved as much as possible. In addition, the division method allows for the main ingredient and the processed ingredient to interact exclusively, after which the processed medicinal is eliminated leaving only the main ingredient. This allows for maximum improvement of the main ingredient. The division method includes the principles of formula composition as well, whose concept could be positioned between single ingredient formulas and common formulas.
