Abstract
BACKGROUND The changes in body image caused by breast deformities and postoperative pain have a detrimental influence on the physical and mental health of patients with breast cancer. The postoperative quality of life (QOL) of these patients reduces significantly owing to the changes in the breast, an organ unique to women, that occur following breast cancer surgery. CASE PRESENTATION This case report presents the case of a Asian woman in her early 40 s with postoperative hypertrophic scarring and contraction of the scar following mastectomy; the patient presented with decreased range of motion of the upper arm, hyperpigmentation from radiation burns, changes in breast shape, and chronic pain. The patient received a combination therapy comprising Basalt Stone Treatment and the application of horse placenta extract. As a result of a total of eight sessions conducted once every two weeks, the patient's pain and scar improved. No adverse events were observed after the therapy. CONCLUSION Combination therapy with Basalt Stone Treatment and horse placenta extract improved the chronic pain and scar after breast cancer surgery.

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.

Atractylodin Produces Antinociceptive Effect through a Long-Lasting TRPA1 Channel Activation. Int J Mol Sci 2021; 22:3614.

Abstract
Atractylodin (ATR) is a bioactive component found in dried rhizomes of Atractylodes lancea (AL) De Candolle. Although AL has accumulated empirical evidence for the treatment of pain, the molecular mechanism underlying the anti-pain effect of ATR remains unclear. In this study, we found that ATR increases transient receptor potential ankyrin-1 (TRPA1) single-channel activity in hTRPA1 expressing HEK293 cells. A bath application of ATR produced a long-lasting calcium response, and the response was completely diminished in the dorsal root ganglion neurons of TRPA1 knockout mice. Intraplantar injection of ATR evoked moderate and prolonged nociceptive behavior compared to the injection of allyl isothiocyanate (AITC). Systemic application of ATR inhibited AITC-induced nociceptive responses in a dose-dependent manner. Co-application of ATR and QX-314 increased the noxious heat threshold compared with AITC in vivo. Collectively, we concluded that ATR is a unique agonist of TRPA1 channels, which produces long-lasting channel activation. Our results indicated ATR-mediated anti-nociceptive effect through the desensitization of TRPA1-expressing nociceptors.

Placental extract suppresses differentiation of 3T3-L1 preadipocytes to mature adipocytes via accelerated activation of p38 MAPK during the early phase of adipogenesis. Nutr Metab (Lond) 2019; 16:32. [PMID: 31139234 PMCID: PMC6528359 DOI: 10.1186/s12986-019-0361-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Accepted: 05/06/2019] [Indexed: 11/17/2022] Open
Abstract
Background Adipogenesis, the process of preadipocyte differentiation to mature adipocytes accompanied by accumulation of intracytoplasmic lipid droplets, is regulated by various genetic and environmental factors, and closely associated with the development of obesity. Numerous recent studies suggest that some bioactive peptides and proteins derived from animals, and chemical compounds isolated from plants may be useful for prevention and treatment of obesity and obesity-related chronic diseases. In the present study, we examined the broad spectrum of effects of placental extract, with a focus on the influence of placental extract on adipogenesis. Method We cultured 3T3-L1 cells, which are widely used as a model of white preadipocytes, under differentiation conditions in the presence of porcine placental extract (PPE) for 8 days, and then stained the lipid droplets accumulated in the cytoplasm with Oil Red O. We also analyzed the effects of PPE on the mitogen-activated protein kinases (MAPKs) signaling, mitotic clonal expansion (MCE) and gene expressions associated with 3T3-L1 differentiation. Results When we cultured 3T3-L1 cells with PPE under differentiation conditions, the accumulation of lipid droplets and expression of adipocyte differentiation marker genes (Cebpa, Pparg, Slc2a4, Fasn and Adipoq) were dramatically attenuated. The suppressive activity of PPE against adipogenesis was heat-stable and recovered in a low-molecular-weight fraction after ultrafiltration (< 3 kDa) and gel-filtration chromatography (fraction No. 9). We also found that the suppressive activity of PPE affected the early phase of adipocyte differentiation (Days 0–2) without influencing the expression levels of C/EBPβ and C/EBPδ. The PPE and fraction No. 9 obtained from gel-filtration chromatography both promoted mitotic clonal expansion of 3T3-L1 while accelerating p38 MAPK phosphorylation. In addition, SB203580, a p38 MAPK inhibitor, partially restored the accumulation of lipid droplets and the expression of adipocyte differentiation marker genes that were suppressed by fraction No. 9. Conclusion These results indicate that PPE suppresses the differentiation of preadipocytes via accelerated activation of p38 MAPK during the early phase of adipogenesis, suggesting PPE or its functional component could be a potential therapy for treating obesity.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is caused by ectopic fat accumulation in the liver. NAFLD is associated with hepatic inflammation and oxidative stress, resulting in nonalcoholic steatohepatitis (NASH) with advanced fibrosis. Placental extracts have been used to treat various chronic diseases due to their antioxidative effect. However, the effects of the extracts on the development of NASH have yet to be elucidated. Here, we demonstrated that supplementation with an oral porcine placental extract (PPE) attenuated lipid accumulation and peroxidation, insulin resistance, inflammatory and stress signaling, and fibrogenesis in the liver of NASH model mice fed a high-cholesterol and high-fat diet. The PPE reduced the number of M1-like liver macrophages, but increased the number of anti-inflammatory M2-like macrophages, resulting in a predominance of M2 over M1 macrophage populations in the liver of NASH mice. Accordingly, the PPE suppressed lipopolysaccharide-induced M1 polarization in isolated murine peritoneal macrophages, whereas it facilitated interleukin 4-induced M2 polarization. Furthermore, the PPE reduced the hepatic stellate cell (HSC) activation associated with the attenuated transforming growth factor-β/Smad3 signaling, both in the liver of NASH mice and in RI-T cells, a HSC line. The PPE may be a potential approach to prevent NASH by limiting lipid peroxidation, promoting M2 macrophage polarization, and attenuating HSC activation.

Abstract
Placenta is a special organ that contains many nutrients such as growth factors, minerals, and bioactive peptides. Dipeptides of glycine and leucine are major components of porcine placenta extracts (PPE) that has been used as an alternative of human placenta extracts. In this study, we investigated whether major peptides of PPE, Glycyl-L-Leucine (Gly-Leu), L-Leucyl-Glycine (Leu-Gly), and L-Leucyl-L-Leucine (Leu-Leu), affect skin hydration and elasticity in vitro and in vivo. We found that Gly-Leu and Leu-Gly dipeptides induced the expression of transglutaminase 1 in normal human epidermal keratinocytes (NHEKs) whereas Leu-Leu dipeptides did not. Treatment with Gly-Leu or Leu-Gly significantly increased hyaluronan (HA) synthesis in NHEKs and the upregulation of hyaluronan synthase 2 (HAS2) mRNA level was confirmed. In addition, elastase activity was inhibited in NHEKs treated with Gly-Leu or Leu-Gly dipeptides. Oral administration of Gly-Leu or Leu-Gly dipeptides increased skin hydration and elasticity in UVB-irradiated hairless mice. The significant upregulation of HA in UVB-irradiated hairless mice was observed in response to oral administration of Gly-Leu or Leu-Gly. These results suggest that the major dipeptides of porcine placenta, Gly-Leu and Leu-Gly, are potentially active ingredients for skin moisturization formulations.

Abstract
OBJECTIVES This study assessed the effects of oral porcine placental extract (PPE) on the mild menopausal symptoms of climacteric women. METHODS In this 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study, 50 climacteric Japanese women were randomized 1 : 1 to oral PPE (300 mg/day) or placebo. Menopausal symptoms were evaluated by using the Simplified Menopausal Index (SMI), as were serum estradiol (E2) and follicle stimulating hormone (FSH) levels. Blood biochemical and cellular and urinary tests were done to evaluate safety aspects of repeated oral administration of PPE. RESULTS The total SMI score of the PPE group was significantly more improved after 12 weeks than that of the placebo group (p = 0.031). This score and three subscores (vasomotor, psychological, and somatic symptoms) were significantly improved at 8 and/or 12 weeks compared with the initial values in the PPE group (p < 0.05). E2 and FSH levels were not improved in either group. No adverse events were observed. CONCLUSIONS Oral PPE at 300 mg/day improved the mild menopausal symptoms of climacteric women. Since oral PPE did not improve serum E2 and FSH levels, PPE is thought not to ameliorate hormonal balance itself but to improve subjective feelings of climacteric women.
