Abstract
To evaluate the efficacy of human placenta hydrolysate (HPH) in a mice model of CFA-induced inflammatory pain. TNF-α, IL-1β, and IL-6 are key pro-inflammatory cytokine factors for relieving inflammatory pain. Therefore, this study investigates whether HPH suppresses CFA-induced pain and attenuates the inflammatory process by regulating cytokines. In addition, the relationship between neuropathic pain and HPH was established by staining GFAP and Iba-1 in mice spinal cord tissues. This study was conducted for a total of day 28, and inflammatory pain was induced in mice by injecting CFA into the right paw at day 0 and day 14, respectively. 100 μL of 20% glucose and polydeoxyribonucleotide (PDRN) and 100, 200, and 300 μL of HPH were administered intraperitoneally twice a week. In the CFA-induced group, cold and mechanical allodynia and pro-inflammatory cytokine factors in the spinal cord and plantar tissue were significantly increased. The five groups of drugs evenly reduced pain and gene expression of inflammatory factors, and particularly excellent effects were confirmed in the HPH 200 and 300 groups. Meanwhile, the expression of GFAP and Iba-1 in the spinal cord was increased by CFA administration but decreased by HPH administration, which was confirmed to suppress damage to peripheral ganglia. The present study suggests that HPH attenuates CFA-induced inflammatory pain through inhibition of pro-inflammatory cytokine factors and protection of peripheral nerves.

Abstract
Metabolic dysfunction-associated steatohepatitis (MASH) is always accompanied with hepatic fibrosis that could potentially progress to liver cirrhosis and hepatocellular carcinoma. Employing a rat model, we evaluated the role of human placental extract (HPE) to arrest the progression of hepatic fibrosis to cirrhosis in patients with MASH. SHRSP5/Dmcr rats were fed with a high-fat and high-cholesterol diet for 4 weeks and evaluated for the development of steatosis. The animals were divided into control and treated groups and received either saline or HPE (3.6 ml/kg body weight) subcutaneously thrice a week. A set of animals were killed at the end of 6th, 8th, and 12th weeks from the beginning of the experiment. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), hepatic malondialdehyde (MDA), and glutathione content were measured. Immunohistochemical staining was performed for α-smooth muscle actin (α-SMA), 4-hydroxy-2-nonenal (4-HNE), collagen type I, and type III. Control rats depicted progression of liver fibrosis at 6 weeks, advanced fibrosis and bridging at 8 weeks, and cirrhosis at 12 weeks, which were significantly decreased in HPE-treated animals. Treatment with HPE maintained normal levels of MDA and glutathione in the liver. There was marked decrease in the staining intensity of α-SMA, 4-HNE, and collagen type I and type III in HPE treated rats compared with control animals. The results of the present study indicated that HPE treatment mediates immunotropic, anti-inflammatory, and antioxidant responses and attenuates hepatic fibrosis and early cirrhosis. HPE depicts therapeutic potential to arrest the progression of MASH towards cirrhosis.

Abstract
The placenta contains multiple biologically active substances, which exert antioxidation, anti-inflammatory, immunomodulatory, and delayed aging effects. Its extract can improve hepatic morphology and function: on the one hand, it can reduce liver interstitial collagen deposition, lipogenesis, and inflammatory cell infiltration and improve fibrosis; on the other hand, it can prevent hepatocellular degeneration by scavenging reactive oxygen species (ROS) and inhibiting inflammatory cytokine production, further improve hepatocyte apoptosis and necrosis, and promote hepatocyte regeneration, making it a promising liver-protective agent. Current research on placenta extract (PE) mainly focuses on treating a specific type of liver injury, and there are no systematic reports. Therefore, this review comprehensively summarizes the treatment reports of PE on liver injury and analyzes its mechanism of action.

Effect of Porcine Placental Extract Mixture on Alcohol-Induced Hepatotoxicity in Rats. Curr Issues Mol Biol 2022; 44:2029-2037. [PMID: 35678666 PMCID: PMC9164070 DOI: 10.3390/cimb44050137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/28/2022] [Accepted: 04/29/2022] [Indexed: 11/18/2022] Open
Abstract
This study was conducted to examine the effect of porcine placenta extract mixture (pPEM, enzymatic/acidic extract = 1/3) on alcoholic hepatotoxicity after pPEM dosing with alcohol in rats. The experimental groups were normal, control, silymarin, three pPEM (590, 1771, and 2511 mg/kg/day, po), and silymarin (100 mg/kg/day, po) groups (n = 10). Alcoholic hepatotoxicity was caused by a liquid ethanol diet for 4 weeks. The effect of pPEM and silymarin on alcoholic hepatotoxicity was evaluated by serology, hepatic ADH and ALDH activities, and histopathological findings. After oral dosing with alcohol for 4 weeks, ALT and AST were significantly increased to 33.7 → 115.6 and 81.37 → 235.0 in the alcohol group, respectively. These levels were decreased significantly to 83.9 and 126.7 in the silymarin group and dose-dependently to 73.6–56.9 and 139.2–122.8 in all pPEM groups. Hepatic ADH and ALDH might have been increased in the control and not in the silymarin and pPEM groups for hepatic ADH. All pPEM groups exhibited no effects on hepatic ALDH except for the high pPEM group. Mild inflammation and fatty lesions were observed in the alcohol group and were attenuated in the silymarin and pPEM groups. As a results, the pPEM showed protective activities against alcoholic hepatotoxicity on the serological markers, hepatic ADH and ALDH, and pathological findings.

Abstract
Objective Epithelial–mesenchymal transition (EMT) is involved in the development of proliferative vitreoretinopathy (PVR) and subsequent fibrosis. Previously, we demonstrated that placental extract ameliorates fibrosis in a mouse model of non-alcoholic steatohepatitis. In this study, we evaluated whether placental extract influences EMT and fibrosis through cytokine-induced EMT in the retinal pigment epithelial cells, in vitro. Results Placental extract did not inhibit EMT, but it suppressed excessive mesenchymal reactions and the subsequent fibrosis. These results suggest that placental extract effectively ameliorates EMT-associated fibrosis in PVR. This beneficial effect could be partially attributed to the suppression of excessive mesenchymal reactions.

Abstract
The COVID-19 pandemic has caused unprecedented health, social, and economic crises worldwide. However, to date, there is an only a limited effective treatment for this disease. Human placenta hydrolysate (hPH) has previously been shown to be safe and to improve the health condition in patients with hyperferritinemia and COVID-19. In this study, we aimed to determine the antiviral effects of hPH against SARS-CoV-2 in vitro and in vivo models and compared with Remdesivir, an FDA-approved drug for COVID-19 treatment. To assess whether hPH inhibited SARS-CoV-2 replication, we determined the CC50, EC50, and selective index (SI) in Vero cells by infection with a SARS-CoV-2 at an MOI of 0.01. Further, groups of ferrets infected with 105.8 TCID50/ml of SARS-CoV-2 and treated with hPH at 2, 4, 6 dpi, and compared their clinical manifestation and virus titers in respiratory tracts with PBS control-treated group. The mRNA expression of immune-related cytokines was determined by qRT-PCR. hPH treatment attenuated virus replication in a dose-dependent manner in vitro. In a ferret infection study, treatment with hPH resulted in minimal bodyweight loss and attenuated virus replication in the nasal wash, turbinates, and lungs of infected ferrets. In addition, qRT-PCR results revealed that the hPH treatment remarkably upregulated the gene expression of type I (IFN-α and IFN-β) and II (IFN-γ) IFNs in SARS-CoV-2 infected ferrets. Our data collectively suggest that hPH has antiviral efficacy against SARS-CoV-2 and might be a promising therapeutic agent for the treatment of SARS-CoV-2 infection.

Abstract
Animal placentae can be used as health-promoting food ingredients with various therapeutic efficacies, but their use is limited by their unpleasant odor and taste. This study aimed to investigate the possibility of deodorization of sheep placenta via yeast fermentation. A yeast strain was successfully isolated and identified as a novel Brettanomyces strain (Brettanomyces deamine kh3). The deodorizing efficacy of fermentation of the sheep placenta with B. deamine kh3 was evaluated by 42 panels, based on evaluation of preference, ranking, and aroma profiles, and compared with normal placenta and placenta fermented with B. bruxellensis. The results of the sensory evaluation indicated that fermentation of the sheep placenta with B. deamine kh3 may improve its palatability by increasing flavors such as that of grass (tree), rubber, and burnt, and by decreasing the odor and soy sauce flavor. Solid-phase microextraction-gas chromatography (SPME-GC) showed that major off-flavors in sheep placenta, such as ammonia, dimethyl disulfide, and 1,3-dioxolane, were completely diminished in the sheep placenta fermented with B. deamine kh3. This study presents those major volatile compounds, including 2-isobutyl\-4,4-dimethyl-1,3-dioxane, and 3-methyl-1-butanol, could be crucial in improving the palatability of the sheep placentae fermented with B. deamine kh3. This study provides a good starting point for the industrial application of a new deodorization method.

Abstract
BACKGROUND Different studies have demonstrated the anti-inflammatory effects of human placental extract both in vivo and in vitro. Considering the chronic inflammatory nature of multiple sclerosis (MS) disease, we examined whether or not the administration of human placental extract is able to attenuate the neurological symptoms detected in experimental autoimmune encephalomyelitis (EAE) model of MS. METHODS The injected myelin oligodendrocyte glycoprotein (MOG) induced EAE in mice, and treatment began from day 4 post-injection by intraperitoneal administration of 0.2 mg/kg human placental extract, repeated every other day up to day 31 post-injection. At the end of the treatment, luxol fast blue (LBS) staining and hematoxylin and eosin (H&E) staining were performed to evaluate the demyelination of neurons and inflammatory responses, respectively. Further assessed were the serum concentrations of IL-23 and IL-27. RESULTS The administration of human placental extract was able to significantly reduce the mean clinical score in EAE mice, decrease the pro-inflammatory process and attenuate neural demyelination. Moreover, while the serum concentration of IL-23 was significantly diminished in the EAE mice receiving human placental extract compared to the non-treated EAE group, IL-27 concentration was significantly increased. CONCLUSIONS Our findings demonstrated the administration of human placental extract could significantly attenuate the neurological symptoms in the EAE model of MS in part through modulating the serum levels of IL-23 and IL-27 and enhancing neuroprotection and myelin repair.

Abstract
Cachexia is an intractable metabolic disorder that causes extreme weight loss. It is a symptom of many chronic diseases, including cancer, liver failure, congestive heart failure and chronic kidney disease, and there is as yet no effective treatment. While the mechanisms underlying cachexia are complex, it is often accompanied by elevated angiotensin II (Ang II). Human placental extract (HPE) is a source of numerous biologically active molecules and has been used clinically to treat chronic hepatitis, liver cirrhosis and other chronic diseases. Here, we investigated the effects of HPE in an Ang II-induced cachexia model in mice. HPE treatment preserved both fat mass and lean body mass and suppressed weight loss in the cachexia model, though food intake was unaffected. Ang II infusion also caused cardiac hypertrophy and fibrosis. HPE suppressed these effects as well as Ang II-induced cardiac expression of genes related to heart failure and cardiac remodeling. HPE also reversed Ang II-induced downregulation of mitochondria-related molecules and suppressed cardiac inflammation and oxidative stress. HPE administration may thus be an effective approach to the treatment of cachexia, cardiac hypertrophy and fibrosis.

Abstract
Though the biological effects of human placental extract have been widely studied, it has limited availability and its use poses ethical problems. Thus, domestic animal placental extracts are suggested as alternatives. In this study, the protective effect of sheep placental extract (SPE) on concanavalin A (Con A)-induced liver injury was investigated. BALB/c mice were randomly divided into six groups, including one normal group and five experimental groups, which received different oral doses of SPE (0, 5, 10 and 50 mg/kg) or a mixture of amino acids for 3 days before Con A injection. Compared with Con A-induced model group, the SPE administration significantly decreased serum aminotransaminase activity, alleviated pathological changes, recovered liver antioxidant capacity and prevented the increase of nitric oxide. Secretion of pro-inflammatory cytokines in serum decreased and mRNA expression of hepatic intercellular adhesion molecule-1, interferon-inducible chemokine 10 and inducible nitric oxide synthase were downregulated, while B-cell lymphoma-2 expression increased. The administration of amino acids mixture had no significant effect in most measurements compared with the model group, which indicated proteins and peptides, rather than individual amino acid, were largely responsible for the bioactivity of SPE. The results indicate SPE has potential therapeutic effects against immune-mediated hepatitis.

Abstract
Placental extract contains several biologically active compounds, and pharmacological induction of placental extract has therapeutic effects, such as improving liver function in patients with hepatitis or cirrhosis. Here, we searched for novel molecules with an anti-tumor activity in placental extracts. Active molecules were separated by chromatographic analysis, and their antiproliferative activities were determined by a colorimetric assay. We identified aspartic acid and glutamic acid to possess the antiproliferative activity against human hepatoma cells. Furthermore, we showed that the combination of aspartic acid and glutamic acid exhibited enhanced antiproliferative activity, and inhibited Akt phosphorylation. We also examined in vivo tumor inhibition activity using the rabbit VX2 liver tumor model. The treatment mixture (emulsion of the amino acids with Lipiodol) administered by hepatic artery injection inhibited tumor cell growth of the rabbit VX2 liver. These results suggest that the combination of aspartic acid and glutamic acid may be useful for induction of tumor cell death, and has the potential for clinical use as a cancer therapeutic agent.

Human placental extract treatment for non-alcoholic steatohepatitis non-responsive to lifestyle intervention: A pilot study. Hepatol Res 2015; 45:1034-1040.

Abstract
AIM No pharmacological therapies have been established for non-alcoholic steatohepatitis (NASH), which can lead to liver-related mortality. Human placental extract (HPE), which has anti-inflammatory effects, has been expected to be a promising treatment for chronic liver disease. This pilot study was conducted to evaluate the efficacy of HPE for biopsy-diagnosed NASH. METHODS After a lifestyle intervention for 12 weeks, 10 subjects with abnormal alanine aminotransferase (≥30 IU/L) and biopsy-proven NASH (Non-Alcoholic Fatty Liver Disease Activity Score [NAS], ≥4) received i.m. injections of HPE (Laennec) at a dose of 4 mL/day twice per week for 24 weeks, and seven of them underwent a second liver biopsy after the treatment. Liver biopsies were scored for NAS and fibrosis. Histological response was defined as a decrease of 2 points or more in NAS and no increase in fibrosis. RESULTS Serum transaminase activities were significantly lower at 8 weeks compared with pretreatment levels in nine patients who continued treatment for 24 weeks. One patient refused to continue the treatment soon after starting therapies. In seven patients undergoing post-treatment biopsies, NAS (mean [standard deviation]) mildly decreased from 5.29 (0.95) to 4.00 (1.83) without reaching statistical significance (P = 0.078). Histological response was observed in all three obese patients and in only one of four non-obese ones. No significant changes were observed in body mass index, lipid profiles and diabetic control/insulin resistance. CONCLUSION In NASH patients who received HPE treatment, significant reductions in serum liver enzymes were obtained after 8 weeks. Histological efficacy may be better in obese patients than in non-obese ones.

Human placental extract exerts hair growth-promoting effects through the GSK-3β signaling pathway in human dermal papilla cells. Int J Mol Med 2015; 36:1088-96.

Abstract
Human placental extract (HPE) is widely used in Korea to relieve fatigue. However, its effects on human dermal papilla cells (hDPCs) remain unknown. In the present study, in an effort to develop novel therapies to promote hair growth, we screened HPE. We demonstrate that HPE has hair growth‑promoting activities and induces β‑catenin expression through the inhibition of glycogen synthase kinase‑3β (GSK‑3β) by phosphorylation in hDPCs. Treatment with HPE significantly increased the viability of the hDPCs in a concentration‑dependent manner, as shown by bromodeoxyuridine (BrdU) assay. HPE also significantly increased the alkaline phosphatase (ALP) expression levels. The increased β‑catenin levels and the inhibition of GSK‑3β (Ser9) by phosphorylation suggested that HPE promoted the hair-inductive capacity of hDPCs. We compared the effects of treatment with HPE alone and treatment with HPE in conjunction with minoxidil (MXD). We found that HPE plus MXD effectively inhibited GSK‑3β by phosphorylation (Ser9) in the hDPCs. Moreover, we demonstrated that HPE was effective in inducing root hair elongation in rat vibrissa hair follicles, and that treatment with HPE led to a delay in catagen progression. Overall, our findings suggest that HPE promotes hair growth and may thus provide the basis of a novel therapeutic strategy for the clinical treatment of hair loss.

Abstract
Human placental extract (HPE) is a traditional medicine that has been used for the symptomatic treatment of liver disease without any verifying clinical evidence. This study aimed to evaluate the efficacy and safety of HPE in patients with alcoholic or nonalcoholic steatohepatitis (ASH or NASH). We designed this clinical trial as a multicenter, open-label, randomized, comparative noninferiority study to improve the reliability of analyses. The enrollment criteria were limited to ASH or NASH patients with serum alanine aminotransferase (ALT) 1.5-fold higher than the normal level. Patients in the control group were treated with a commercially available mixture of liver extract and flavin adenine dinucleotide (LE–FAD). Intention-to-treat (ITT) analysis was applied to 194 patients, and per-protocol (PP) analysis was available for 154 patients. The rate of primary goal achievement of treatment efficacy was arbitrarily defined as 20% or greater improvement in ALT level compared with the pretreatment level and did not differ significantly between the HPE and control groups [62.9% (44/70) vs. 48.8% (41/84); p=0.0772]. ITT and modified ITT analysis showed results similar to those of PP analysis. Adverse drug reactions (ADRs) of minimal to moderate degree occurred in 3.1% of patients. The ADR and treatment compliance rates were similar in both groups. In conclusion, the clinical value of HPE in the treatment of ASH and NASH is equivalent to that of LE–FAD.

Abstract
Dry eye syndrome (DES), a multifactorial disease of the tears and ocular surface, is one of the most common ocular disorders. Tear film contains ocular mucins and is essential for maintaining the homeostasis of the wet ocular surface. Since there are a limited number of clinical options for the treatment of DES, additional novel treatments are needed to improve the clinical results. In this study, we found that placental extract-derived dipeptide (JBP485) clearly promoted the expression and secretion of gel-forming mucin 5ac (Muc5ac) in rabbit conjunctival epithelium. JBP485 also elevated the expression level of cell surface-associated mucins (Muc1/4/16) in rabbit corneal epithelium. The Schirmer tear test results indicated that JBP485 induced tear secretion in the rabbit model. Moreover, JBP485 clinically improved corneal epithelial damage in a mouse dry eye model. Thus, our data indicate that JBP485 efficiently promoted mucin and aqueous tear secretion in rabbit ocular surface epithelium and has the potential to be used as a novel treatment for DES.

Abstract
Placenta, as a reservoir of nutrients, has been widely used in medical and cosmetic materials. Here, we focused on the antioxidant properties of placental extract and attempted to isolate and identify the main antioxidant factors. Porcine placental extracts were prepared through homogenization or acid hydrolysis, and their antioxidant activity was investigated in the human keratinocyte HaCaT cell line. Treatment with homogenized placental extract (H-PE) increased the cell viability of H2O2-treated HaCaT cells more than two-fold. H-PE treatment suppressed H2O2-induced apoptotic and necrotic cell death and decreased intracellular ROS levels in H2O2-treated HaCaT cells. The antioxidant factors in H-PE were found to be thermo-unstable and were thus expected to include proteins. The candidate antioxidant proteins were fractionated with cation-exchange, anion-exchange, and size-exclusion chromatography, and the antioxidant properties of the chromatographic fractions were investigated. We obtained specific antioxidant fractions that suppressed ROS generation and ROS-induced DNA strand breaks. From silver staining and MALDI-TOF analyses, alpha-fetoprotein (AFP) precursor was identified as a main marker for the antioxidant effect of H-PE. Purified AFP or ectopically expressed AFP exhibited synergistic antioxidant activity in the presence of estradiol. Taken together, our data suggest that AFP, a serum glycoprotein produced at high levels during fetal development, is a novel marker protein for the antioxidant effect of the placenta that exhibits synergistic antioxidant activity in the presence of estradiol.

Abstract
A simple and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of JBP485, Gly-Sar and JBP923 in the cell lysates using methanol as a deproteinization solvent was developed and validated. Detection was performed by turbo ionspray ionization in multiple reaction monitoring mode using the transitions of m/z 147.1 → m/z 90.1 for Gly-Sar, m/z 201.1 → m/z 86.1 for JBP485, m/z 219.1 → m/z 86.1 for JBP923 and m/z 152.0 → m/z 110.0 for paracetamol (internal standard). The analytes were separated on a Hypersil ODS C18 HPLC column using isocratic elution mode with a mobile phase containing 0.1% formic acid in water-methanol (97:3, v/v) at a flow rate of 0.2 mL/min. The calibration curves were demonstrated to be linear over the concentration range of 5.00-5000 nm with coefficient of 0.9968 for Gly-Sar, 0.9975 for JBP485 and 0.9952 for JBP923. The intra- and inter-day precisions were <10.2% for each quality contro; level, and the accuracy was within ±5.6% for each analyte. The matrix effect, the extraction recovery and stabilities of LC-MS/MS analysis were also investigated. This validated method was successfully applied to the simultaneous determination of JBP485, Gly-Sar and JBP923 in the cell lysates for identification of stably transfected HeLa cells with human PEPT1.

Abstract
Placental extracts have been reported to have anti-oxidative and anti-inflammatory activities. Because there is increasing evidence that ionizing radiation induces the release of reactive oxygen species (ROS) and inflammatory cytokines, we examined the protective effects of a placental extract against radiation injury. C57BL/6 mice were exposed to 1 Gy of γ-ray radiation every day for 5 days, and placental extract (1 mg/day) was administrated orally soon after each exposure. At 2 days after the last irradiation, mice were euthanized to examine the numbers, colony-forming capacity, and DNA damage of stem/progenitor cells in the peripheral blood and bone marrow. To understand the related mechanisms, we also measured the levels of intracellular and mitochondrial ROS, and 8-OHdG in the plasma and urine, and IL-6 and TNF-α in the plasma. Compared with the placebo treatment, oral administration of placental extract significantly increased the number and colony-forming capacity, but decreased the DNA damage of bone marrow stem/progenitor cells. However, neither the levels of intracellular and mitochondrial ROS in bone marrow cells, nor the levels of 8-OHdG in the urine and plasma significantly differed between groups. Interestingly, in comparison with the placebo treatment, placental extract significantly decreased the levels of the inflammatory cytokines IL-6 and TNF-α in the plasma. Placental extract significantly attenuated the acute radiation injury to bone marrow-derived stem/progenitor cells, and this protection is likely to be related to the anti-inflammatory activity of the placental extract.

Abstract
The purpose of this study is to investigate whether the effect of cyclo-trans-4-l-hydroxyprolyl-l-serine (JBP485) on acute renal failure (ARF) induced by cisplatin is related to change in expression of renal Oat1, Oat3 and Mrp2 in rats. JBP485 reduced creatinine, blood urea nitrogen (BUN) and indoxyl sulfate (IS) in plasma and malondialdehyde (MDA) in kidney, and recovered the glomerular filtration rate (GFR) and the activity of superoxide dismutase (SOD) in cisplatin-treated rats. The plasma concentration of PAH (para-aminohippurate) determined by LC-MS/MS was increased markedly after intravenous administration of cisplatin, whereas cumulative urinary excretion of PAH and the uptake of PAH in kidney slices were significantly decreased. qRT-PCR and Western-blot showed a decrease in mRNA and protein of Oat1 and Oat3, an increase in mRNA and protein of Mrp2 in cisplatin-treated rats, and an increase in IS (a uremic toxin) after co-treatment with JBP485. It indicated that JBP485 promoted urinary excretion of toxins by upregulating renal Mrp2. This therefore gives in part the explanation about the mechanism by which JBP485 improves ARF induced by cisplatin in rats.

Abstract
OBJECTIVES Injections of human placental extract have long been used to treat menopausal symptoms. Recently, porcine placental extract (PPE), an oral supplement, has been developed for this purpose. The aim of this study was to assess whether PPE has an impact on climacteric symptoms in perimenopausal and postmenopausal women. METHODS Seventy-six women with climacteric symptoms were enrolled into this open-label, randomized, controlled study. The control group (n = 38) underwent 24 weeks of open treatment with Toki-shakuyaku-san (TJ23), an oral herbal remedy used to alleviate climacteric symptoms. The PPE group (n = 38) received three capsules of PPE/day orally for the initial 12 weeks and six capsules/day for the next 12 weeks. Climacteric symptoms were evaluated in both groups using the Simplified Menopausal Index (SMI) score, Zung's Self-Rating Depression Scale (ZSDS) and the Spielberger State-Trait Anxiety Inventory (STAI) before commencing treatment, after 12 weeks of treatment and on completion of treatment. RESULTS Treatment with PPE was significantly (p < 0.01) more effective in reducing the SMI, ZSDS and STAI measures at 12 and 24 weeks than TJ23 treatment alone. Treatment with PPE was also significantly effective (p < 0.01) in reducing the subscale scores of the SMI for items such as hot flushes, insomnia, irritability, depression, fatigue and joint pain. PPE treatment had no significant adverse effects. CONCLUSION Oral PPE treatment is another possible option for treating perimenopausal and postmenopausal women with climacteric symptoms.

Liu T, Guo X, Meng Q, Wang C, Liu Q, Sun H, Ma X, Kaku T, Liu K. Effect of JBP485 on obstructive jaundice is related to regulation of renal Oat1, Oat3 and Mrp2 expression in ANIT-treated rats. Peptides 2012; 36:78-85. [PMID: 22521734 DOI: 10.1016/j.peptides.2012.04.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2012] [Revised: 04/03/2012] [Accepted: 04/03/2012] [Indexed: 11/26/2022]
Abstract
The objective was to determine whether protective effects of JBP485 on biliary obstruction induced by alpha-naphthylisothiocyanate (ANIT) are mediated by the organic anion transporters Oat1, Oat3 and the multidrug resistance-associated protein Mrp2. The ANIT-induced increases in bilirubin (BIL), alanine aminotransferase (ALT) and aspartate transaminase (AST) in rat serum were inhibited significantly by oral administration of JBP485. The plasma concentration of JBP485 which is the substrate of Oat1 and Oat3 determined by LC-MS/MS was markedly increased after intravenous administration in ANIT-treated rats, whereas cumulative urinary excretion of JBP485 in vivo and the uptake of JBP485 in kidney slices were decreased remarkably. RT-PCR and Western blot showed the decreased expression of Oat1 and Oat3, increased expression of Mrp2 in ANIT-induced rats, meanwhile, the expression levels of Mrp2 and Oat1 were up-regulated after administration of JBP485. The up-regulation of Mrp2 and Oat1 was associated with a concomitant increase in urinary BIL after treatment with JBP485 in ANIT-treated rats. The mechanism for JBP485 to restore liver function might be related to improvement of the expression and function for Oat1 and Mrp2 as well as facilitation of urinary excretion for hepatoxic substance.

Abstract
The purpose of this study was to construct stably transfected HeLa cells with human peptide transporters (hPEPT1/hPEPT2) and to identify the function of the transfected cells using the substrate JBP485 (a dipeptide) and a typical substrate for PEPTs, glycylsarcosine (Gly-Sar). An efficient and rapid method was established for the preparation and transformation of competent cells of Escherichia coli. After extraction and purification, hPEPT1/hPEPT2-pcDNA3 was transfected into HeLa cells by the liposome transfection method, respectively. HeLa-hPEPT1/hPEPT2 cells were selected by measuring the protein expression and the uptake activities of JBP485 and Gly-Sar. A simple and rapid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of JBP485 and Gly-Sar in biological samples. The Michaelis-Menten constant (K(m)) values of Gly-Sar uptake by the hPEPT1 and hPEPT2-expressing transfectants were 1.03 mM and 0.0965 mM, respectively, and the K(m) values of JBP485 uptake were 1.33 mM for PEPT1 and 0.144 mM for PEPT2. The uptake of Gly-Sar was significantly inhibited by JBP485 with a K(i) value of 8.11 mM (for PEPT1) and 1.05 mM (for PEPT2). Maximal uptake of Gly-Sar were detected at pH 5.8 (for PEPT1) and pH 6.5 (for PEPT2), suggesting that both HeLa-hPEPT1 and HeLa-hPEPT2 were H(+) dependent transporters. Stably transfected HeLa-hPEPT1/HeLa-hPEPT2 cells were constructed successfully, and the functions of hPEPT1/hPEPT2 were identified using their substrates, JBP485 and Gly-Sar. The transfected cells with transporters were used to investigate drug-drug interactions (DDIs) between JBP485 and other substrates (cephalexin or lisinopril) of PEPT1 and PEPT2.

Abstract
Objectives. Human placental extract (HPE) has begun to be used in Korea in various ways to improve health, even though evidence-based data is insufficient. This study investigated the effects of HPE on health status in elderly Koreans. Design. Randomized, single-blind, and case-control study design. Setting and Participants. Thirty-nine community-dwelling healthy Koreans ≥65 years of age. Intervention. The participants were randomly categorized into a placebo group (n = 17) and HPE group (n = 22). The HPE group received abdominal subcutaneous injections of HPE for 8 weeks. The placebo group was injected with normal saline. Measurements. The degree of health status was surveyed by the Korean health status measure for the elderly (KoHSME V1.0) at baseline and the end of the study. Results. In the HPE group, the scores of physical function, sexual life, and general heath perception at the end of the study period were significantly improved from baseline (P = .007, .020, and .005, resp.), while the health status of the placebo group remained unchanged during the study period. There was a significant difference over the study period between the two groups in the mean change of the physical function score (P = .036). Conclusion. A HPE injection regimen can improve the health status in elderly Koreans.

Abstract
Bestatin, a dipeptide, a low molecular weight aminopeptidase inhibitor, has been demonstrated to be an immunomodulator with an antitumor activity. However, the transporter-mediated renal excretion of bestatin is not fully understood. The purpose of this study was to elucidate the transporter-mediated renal excretion mechanism for bestatin. The plasma concentration of bestatin was increased markedly and both the accumulative renal excretion and renal clearance of bestatin were decreased significantly after intravenous administration of bestatin in combination with probenecid. p-Aminohippuric acid (PAH), a substrate of organic anion transporter (OAT) 1, benzylpenicillin (PCG), a substrate of OAT3 and JBP485, a substrate of OAT1 and OAT3, reduced the uptake of bestatin in rat kidney slices and in hOAT1- or hOAT3-HEK 293 cells. The accumulation of bestatin in hOAT1-HEK and hOAT3-HEK 293 cells was significantly greater than that in vector-HEK, and the K(m) and V(max) were 0.679 ± 0.007 mM and 0.807 ± 0.006 nmol/mg protein/30s for OAT1, 0.632 ± 0.014 mM and 1.303 ± 0.015 nmol/mg protein/30s for OAT3 respectively. PAH and JBP485 inhibited significantly the uptake of bestatin in hOAT1-HEK with the K(i) values of 92 ± 9 μM and 197 ± 21 μM; and PCG, JBP485 inhibited significantly the uptake of bestatin in hOAT3-HEK 293 cells with the K(i) values of 88 ± 12 μM and 160 ± 16 μM. Our results are novel in demonstrating for the first time that OAT1 and OAT3 are involved in the renal excretion of bestatin.

Abstract
The purpose of this study was to clarify the pharmacokinetic mechanism of interaction between JBP485 (cyclo-trans-4-L-hydroxyprolyl-L-serine, a dipeptide with antihepatitis activity) and lisinopril (an angiotensin-converting enzyme inhibitor) in vitro and in vivo. When JBP485 and lisinopril were administered orally simultaneously, the plasma concentrations of the two drugs were decreased significantly, but few changes were observed after simultaneous intravenous administration of the two drugs. The uptake of JBP485 and lisinopril in everted intestinal sacs and in HeLa cells transfected with human peptide cotransporter 1 (PEPT1), as well as absorption of JBP485 and lisinopril after jejunal perfusion were reduced after simultaneous drug administration, which suggested that the first target of drug interaction was PEPT1 in the intestine during the absorption process. The cumulative urinary excretions and renal clearance of the two drugs were decreased after intravenous co-administration, while uptakes of the two drugs in kidney slices and hOAT1/hOAT3-transfected HEK293 cells were decreased. These results indicated that the second target of drug-drug interaction was located in the kidney. These findings confirmed that the pharmacokinetic mechanism of interaction between JBP485 and lisinopril could be explained by their inhibition of the same transporters in the intestinal mucosa (PEPT1) and kidneys (OATs).

Abstract
OBJECTIVES Knee pain related to osteoarthritis increases with age and is more common in middle-aged women. Although hormone replacement therapy (HRT) improves knee pain, women unresponsive to HRT need an effective adjunctive therapy. The aim of this study was to assess whether oral porcine placental extracts (PPE) have an impact on patients with knee pain as an adjunctive therapy combined with HRT. METHODS Forty-eight postmenopausal women with knee pain receiving HRT were enrolled into this open-label, randomized, controlled study. Subjects were randomized into Group 1 (n= 24) or Group 2 (n=24). Subjects in Group 1 were given 3 months open treatment with calcium (260 mg/day) as adjunctive therapy combined with HRT. Group 2 received PPE (9 capsules/day) as adjunctive therapy combined with HRT. Changes in the degree of knee pain were evaluated by the Visual Analog Scale (VAS). RESULTS Treatment with PPE was significantly effective in reducing the VAS score for knee pain at 4 weeks (p < 0.05), at 8 weeks (p< 0.01) and at 12 weeks (p<0.01), compared with the control group. Interestingly, the effects continued for 4 weeks after cessation of treatment in the PPE group (p< 0.01) compared with the control group. The PPE treatment had no significant adverse effects on blood biochemical and metabolic profiles, especially related to the risk factors for cardiovascular disease. CONCLUSION PPE is a possible option as an adjunctive oral supplement in the case of HRT-resistant, long-lasting knee pain.

Abstract
The human placenta is an organ for fetus development and abundant reservoir of various bioactive molecules. Interest to human placenta extract (hPE) is growing, and application with trial of hPE is widening in oriental medicine including in liver diseases. However, underlying mechanisms for therapeutic effects are still unclear. Here, we investigated therapeutic effects of hPE in carbon tetrachloride (CCl(4))-injured rat liver model in vivo and in damaged rat hepatic cells exposed to CCl(4) in vitro. In addition, regulation of inflammatory responses by treatment of hPE was investigated. Serum levels of GOT/AST and GPT/ALT were significantly reduced (P<0.05), and uptake/excretion of indocyanine green in serum was significantly induced at 3 weeks after intravenous hPE administration in CCl(4)-injured rat model (P<0.05). Expression of type I collagen (Col I) and α-smooth muscle actin (α-SMA) was decreased, whereas that of matrix metalloproteinase-9 (MMP-9) was increased resulting in improvement of score for fibrotic grade in hPE group. Also, albumin, proliferation activities and molecules associated with liver regeneration (e.g. interleukin-6, gp130, ATP binding cassette transporters, cyclin A) were more increased in hPE administration group than Non-hPE group. hPE administration suppressed activated T-cell proliferation via increasing anti-inflammatory cytokines and decreasing pro-inflammatory cytokines. These results suggest that hPE could be effective for liver disease through reduction of fibrosis, induction of liver regeneration, and regulation of inflammatory responses. These findings are important for understanding the roles of hPE and provide evidences for therapeutic effects of hPE in hepatic diseases which could lead to potential clinical applications.

Abstract
A 7-year-old Miniature Dachshund presented with severe chronic jaundice and elevated liver enzymes. Destructive cholangitis was diagnosed according to histopathological findings of remarkable ductopenia with inflammatory infiltrates and fibrosis in the portal areas. Supportive therapy with prednisolone, high-dose ursodeoxycholic acid, human placental extract and antibiotics was tried, and the patient showed recovery of clinical signs 3 months after diagnosis. A second liver biopsy was performed about 1 year after initial diagnosis, and bile duct restoration was confirmed with continuous inflammation around portal areas and inside the lobules. Although we could not determine which treatment was effective in this case, destructive cholangitis in dogs may be recoverable with long-term supportive therapies.

Abstract
OBJECTIVES Translational research using adult stem cells derived from various tissues has been highlighted in cell-based therapy. However, there are many limitations to using conventional culture systems of adult stem cells for clinically applicability, including limited combinations of cytokines and use of nutrients derived from animals. Here, we have investigated the effects of placental extract (PE) for culture of placenta-derived stem cells (PDSCs) as well as their potential for hepatogenic differentiation. MATERIALS AND METHODS Placental extract, extracted using water-soluble methods, was used as a supplement for culture of PDSCs. Cell viability was determined using the MTT assay, and cytokine assay was performed using Luminex assay kit. Gene expression, indocyanine green (ICG) up-take, PAS (Periodic Acid-Schiff) staining and urea production were also analysed. RESULTS The placental extract contained several types of cytokine and chemokine essential for maintenance and differentiation of stem cells. Expression of stemness markers in PDSCs cultured with PE is no different from that of PDSCs cultured with foetal bovine serum (FBS). After hepatogenic differentiation, expression patterns for hepatocyte-specific markers in PDSCs cultured with PE were consistent and potential for hepatogenic differentiation of PDSCs cultured with PE was similar to that of PDSCs cultured with FBS, as shown by PAS staining and urea production assays. CONCLUSIONS Our findings revealed that placental extract could be used as a new component for culture of adult stem cells, as well as for development of human-based medium, in translational research for regenerative medicine.

Abstract
Immunoregulatory effects of placental extract and placenta-derived factors have been demonstrated in various conditions. Accordingly, placental extract has been used as certain types of medical intervention in Asian countries, whereas experimental evidence supporting its therapeutic effects and mechanisms has yet to be fully demonstrated. In this study, we investigate preventive and therapeutic effects of placental extract in contact hypersensitivity (CHS), a mouse model of allergic contact dermatitis. Administration of placental extract prior to the sensitization of allergic antigen (Ag) significantly inhibited the severity of CHS induced by Ag challenge. This effect was associated with reduced numbers of CD4(+) T cells in peripheral blood, decrease of tissue-infiltrating lymphocytes, and preferential production of Th2-type cytokines in Ag-challenged sites. In addition, CHS caused by repetitive challenges of allergic Ag was also prevented and treated by administration of placental extract. Finally, administration of cyclo-trans-4-L-hydroxyprolyl-L-serine, a dipeptide derived from placental extract, also alleviated CHS, suggesting its potential role in the effects of placental extract in CHS. Taken together, our findings demonstrated experimental evidence supporting immunoregulatory effects of placental extract in allergic skin diseases and elucidated its potential mechanisms.

Abstract
Abstract
Objectives
Cyclo-trans-4-L-hydroxyprolyl-L-serine (JBP485) was first isolated from Laennec (hydrolysate of human placenta). We thought it valuable to clarify the antihepatitis molecular mechanism of JBP485 to develop a new oral anti-hepatitis drug.
Methods
We investigated the hepatoprotective effect of JBP485 on immune-mediated, concanavalin A (Con A)-induced liver injury in mice. Mice were administered JBP485 before and after injection of Con A (10 mg/kg). Eight hours after Con A, the cytosolic enzyme activity (alanine aminotransferase, lactate dehydrogenase) in serum, and the enzyme activity or concentration (superoxide dismutase, maleic dialdehyde, myeloperoxidase, nitric oxide) in liver homogenate were determined. The liver slices were investigated to observe changes in histology. The effect of JBP485 on level of tumour necrosis factor-α (TNF-α) and intercellular adhesion molecule-1 (ICAM-1) in liver were detected by immunohistochemistry. Hepatocyte DNA fragmentation was assayed by agarose gel electrophoresis and the transcription of the genes bax and bcl-2 in hepatocytes was determined by reverse transcription-polymerase chain reaction.
Key findings
Con A increased the cytosolic and liver homogenate enzyme activity, and the concentrations of ICAM-1 and TNF-α, which were significantly inhibited by JBP485 administration. Also, the increase in DNA fragmentation and decrease in bcl-2/bax mRNA induced by Con A administration were significantly inhibited by JBP485.
Conclusions
These results indicated that immune-mediated liver damage can be prevented by JBP485, and that this is mainly associated with immunomodulatory effects on T cells and adhesion molecules, antioxidation, and inhibition of apoptosis.

Abstract
The effect of Laennec, a hydrolyte of human placenta, on immune-mediated liver injury was investigated in vivo and in vitro in murine. Vena caudalis administration of concanavalin A (Con A) was employed to establish an in vivo liver-injury model, and in vitro hepatotoxicity was induced by 8 h interaction between Con A pre-treated hepatocytes and Con A-stimulated autologous splenic lymphocytes. Laennec was used for pre-treatment in the two models. Laennec decreased biochemical marker activity (alanine aminotransferase, ALT; lactate dehydrogenase, LDH) in serum and recovered the activity of superoxide dismutase (SOD) and myeloperoxidase (MPO), as well as the content of malondialdehyde (MDA) and nitric oxide (NO) in liver tissue. We also found that the DNA ladder induced by Con A in vivo was attenuated by Laennec. Furthermore, the leakage of aspartate aminotransferase (AST) and LDH in the supernatant of the co-culture system was decreased by addition of Laennec. Potential protective mechanisms were elucidated by DNA fragmentation assay and intercellular adhesion molecule-1 (ICAM-1) induction/inhibition experiments. Results showed that ICAM-1, which is related to the interaction between hepatocytes and lymphocytes, was inhibited by Laennec. These findings indicated that Laennec has potent activity against immune-mediated liver injury.

Canine bone marrow cells differentiate into hepatocyte-like cells and placental hydrolysate is a potential inducer. Res Vet Sci 2009; 87:1-6. [PMID: 19121529 DOI: 10.1016/j.rvsc.2008.11.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2008] [Revised: 11/10/2008] [Accepted: 11/19/2008] [Indexed: 01/29/2023]
Abstract
Hepatocyte growth factor (HGF) can stimulate human and rat bone marrow (BM) cells to differentiate into hepatocytes. A human placental hydrolysate (hPH) stimulates proliferation of hepatocytes, but its role as a potential inducer of BM cells to form hepatocytes is unclear. To determine if canine BM cells stimulated with HGF or hPH differentiate into hepatocyte-like cells, BM cells were cultured with HGF or hPH. The cultured cells underwent morphological examination, expression of albumin and cytokeratin 18 (CK18), hepatic function tests including uptake of low-density lipoprotein (LDL) and cytochrome P (CYP) 450 activity. Albumin mRNA and protein expression of albumin and CK18 proteins were detected in cultures with HGF and hPH. Furthermore, these cells demonstrated LDL uptake and CYP450 activity. These results indicate that canine BM cells can differentiate into hepatocyte-like cells when stimulated by both HGF and that hPH may be an effective inducer of hepatic differentiation.

Abstract
OBJECTIVE In Korea, human placental extract (HPE) has recently been used to treat various diseases (chronic liver diseases, menopause syndrome, chronic fatigue, skin pigment diseases, etc.), but evidence-based studies are not yet sufficient. The aim of this study was to examine the effects of HPE on menopausal symptoms, fatigue, and risk factors for cardiovascular disease in middle-aged Korean women in a randomized controlled trial. DESIGN Korean women, aged 40 to 64 years, with menopausal symptoms and fatigue were recruited as participants. The women were randomly assigned to a placebo group or an HPE group. The HPE group received subcutaneous injections of HPE in the abdomen for 8 weeks, whereas the placebo group received normal saline. Then, the Menopause Rating Scale, and Fatigue Severity Scale, and Visual Analog Scale were administered, and risk factors for cardiovascular disease were assessed. RESULTS The Menopause Rating Scale total baseline score was not different between the two groups; however, the score of the HPE group decreased significantly at 8 weeks compared with that of the placebo group (P = 0.033). Fatigue Severity Scale and Visual Analog Scale scores of the placebo group did not change, whereas the scores of the HPE group decreased significantly during the study period (Fatigue Severity Scale, P = 0.002; Visual Analog Scale, P = 0.001). The baseline 17beta-estradiol level was not significantly different between the two groups, but the 17beta-estradiol level of the HPE group was significantly increased at 8 weeks compared with that of the placebo group (P = 0.031). No changes in risk factors for cardiovascular disease were observed in either group. CONCLUSIONS Menopausal symptoms and fatigue in middle-aged Korean women improved after 8 weeks of HPE treatment, whereas risk factors for cardiovascular disease did not change during the study period.
