The Effect of Equine Placental Extract on Anti-inflammatory and Anti-oxidant Activity of the Skin / 日本補完代替医療学会誌

The anti-inflammatory and anti-oxidant effect of equine placental extract (ePE) on epidermal keratinocytes was examined. ePE reduced mRNA levels of TNF-α (Tumor Necrosis Factor-α) and IL-6 (Interleukin-6) among the inflammatory cytokines released by epidermal keratinocytes after ultraviolet light (UVB: 290-320 nm) exposure. ePE also activated Nrf2, a transcription factor known to be activated by oxidative stress to promote the expression of antioxidant enzymes and suppress inflammation, and it increased the mRNA level of the antioxidant enzyme HO-1 (Heme Oxygenase-1). These results suggest that ePE suppresses UV-induced inflammation of epidermal keratinocytes via activation of Nrf2.

A Case of Androgenetic Alopecia (AGA) Successfully Treated with Combined Treatment of Basalt Stone Treatment and Placenta Extract: A Case Report / 日本補完代替医療学会誌

Improvement of hair thinning was observed after a novel treatment course involving basalt stone and placental extract application in a patient of androgenetic alopecia. The patient was resistant to the general home care treatment. The response to the new treatment may be attributed to the decreased scalp hardness secondary to the improved blood circulation after basalt stone massage and the hair growth-promoting action of the placental extract. Furthermore, recurrence of hair thinning was observed after suspension of this treatment; however, this hair thinning improved when the treatment was resumed.

The Effect of Equine Placental Extract on Anti-skin Aging Activity / 日本補完代替医療学会誌

In the present study, we assessed the antiaging effect of equine placental extract (ePE) on dermal fibroblasts and found that it markedly suppressed the appearance of β-galactosidase-positive cells among the senescent cells induced by repeated hydrogen peroxide exposure or ultraviolet A irradiation. Moreover, the efficacy of ePE treatment was similar to that of an antioxidant, N-acetylcysteine. Thus, owing to its antioxidant effect, ePE can be used as an antiaging agent, particularly for the dermis.

Study on the Effect of Porcine Placental Extract Ingestion on Symptoms of Late-onset Hypogonadism Syndrome in Middle-aged and Elderly Men / 日本補完代替医療学会誌

Purpose: An open-label, single-arm study was conducted to evaluate the effectiveness of porcine placental extract (PPE) ingestion to improve late-onset hypogonadism (LOH) syndrome symptoms. In addition, we reported the safety of continuous PPE ingestion in biochemistry tests.Materials and Methods: Test food containing PPE was given daily to healthy male subjects with an Aging Males’ Symptoms (AMS) score of ≥27, who were assessed as having LOH syndrome. AMS score, blood hormone level, and other parameters were measured before the start of PPE ingestion, Week 4, and Week 8. And adverse events that occurred during the ingestion period were accumulated.Results: Excluding one subject who withdrew from the study due to an adverse event unrelated to the test food, 14 subjects were included in the analysis. In terms of AMS score, no improvement was observed at Week 4, whereas a significant improvement was observed at Week 8. AMS scores were further categorized into three subscales (psychological, somatic, and sexual) and analyzed. The results showed a significant improvement from baseline in somatic scores at Week 8. Meanwhile, no significant change in sexual hormone levels was observed. At Week 8, improvements from baseline were observed in renal function and LDL cholesterol level. There were no adverse events related to the test food.Conclusion: The study demonstrated that 8-week PPE ingestion in middle-aged and elderly men can improve LOH syndrome symptoms while having little effect on sexual hormone secretion.

Experimental evaluation of anticonvulsant effect of human placental extract in pentylenetetrazole induced convulsions in mice.

Background: Human placental extract (HPE) is used in different clinical conditions. Human placental extract (HPE), a folklore medicine, prepared from fresh, healthy human placenta has been in use, as single dose therapy in the treatment of epilepsy in some parts of India. Hence, present study was carried out to explore anticonvulsant property of Human placental extract (HPE) in Pentylenetetrazole (PTZ) induced convulsions in albino mice. Methods: Effects of human placental extract (HPE) (1.0, 1.2 and 1.4 ml / 100 gm body weight) as test drug, sodium valproate (150 mg / kg body weight) as standard and distilled water as control were studied in pentylenetetrazole (PTZ) induced convulsions in albino mouse model. Failure to observe even a single episode of tonic spasm for 5 sec. duration for 1 hour was taken as index of anticonvulsant activity. Onset, duration, complete recovery from convulsion and percent protection was calculated and statistical analysis was carried out using student ‘t’ test. Results: Pretreatment with human placental extract (HPE) administered in the dose of 1.0 ml / 100 gm body weight provided 33.33% and in the doses of 1.2 and 1.4 ml / 100 gm body weight and sodium valproate provided 100% protection from convulsions induced by Pentylenetetrazole in albino mice. Conclusion: Human placental extract (HPE) has shown promising anticonvulsant effect on Pentylenetetrazole induced mouse model.

OBJECTIVES: The objective of this study was to evaluate the efficacy of Unicenta (UNCNT) and Melsmon in women with the menopausal symptoms, by analysing the changes in the Kupperman index (primary endpoint), and the hormonal change (secondary endpoint). METHODS: This is a randomized, multi-Center, double-Blind, parallel, non-inferiority clinical study of four different tertiary medical centers. We began the participant recruitment in September 2011, with 218 patients applied over 7 months. All participants had the last visit in April 2012. RESULTS: The Unicenta injection was not inferior to that of Melsmon as measured by the Kupperman index following the injection in both the intent-to-treat and the per-protocol populations (P = 0.63, P = 0.85, respectively). Side effects occurred in 14.0% of the cases (15 patients/18 cases) in the case group, and in 12.6% (14 patients/15 cases) in the control group (P value=0.7599). None were reported to be associated with the medication. The laboratory results and the vital signs showed no statistically significant risk for safety. CONCLUSION: The study showed that Unicenta is not inferior to Melsmon in the change of the Kupperman index after 12 days of injection. The efficacy and safety of Unicenta was shown, with the improvement of the menopausal symptoms.

The Effect of Human Placental Extract on Rheumatoid Arthritis in an Animal Model

OBJECTIVE: To assess the efficacy of human placental extract (HPE) in an animal model of rheumatoid arthritis (RA). METHOD: We used (i) KRN C57BL/6 TCR transgenic x NOD mice (KBx/N) serum transfer arthritis and (ii) collagen-induced arthritis (CIA) mice to evaluate the effi cacy of HPE (1 ul or 100 ul, intra-peritoneal, three times per week) on RA. Incidence, severity of arthritis, and hind-paw thickness were quantifi ed. Joint destruction was analyzed using modifi ed mammographic imaging. Histopathological analysis for inflammation, cartilage, and osteoclasts was performed using Hematoxylin-eosin (H-E), safranin-O, and tartrate-resistant acidic phosphatase (TRAP). ELISAs were used for detection of various cytokines in serum and joint tissue. RESULTS: There were no significant differences in incidence of arthritis, clinical scores of arthritis, and hind-paw thickness between HPE-treated and vehicle-treated groups for up to 2 weeks in the KBx/N serum transfer arthritis model. Histopathological analysis also showed no differences 2 weeks after treatment. Levels of TNF-alpha, IL-1beta, IL-6, IL-10, and RANKL in serum and joint tissues were similar in all groups. Furthermore, there were no differences in clinical, radiological, and histological parameters between HPE-treated and vehicle-treated group for 3 weeks in the CIA model. CONCLUSION: Systemic treatment with HPE has no beneficial effects on arthritis in animal models of RA. Therefore, indiscreet use of HPE in RA should be forbidden.

Topical placental extract: Does it increase the efficacy of narrowband UVB therapy in vitiligo.

Background: Narrowband UVB therapy is presently one of the most effective therapies for generalized vitiligo. Many topical agents have been used in combination with narrowband UVB therapy to increase its efficacy in causing repigmentation in vitiligo. Placental extract is used topically usually in combination with sun exposure to cause repigmentation of vitiligo lesions. Aims: The present study aims to study whether the efficacy of narrowband UVB therapy would be enhanced by addition of topical placental extract to the treatment regimen. Methods: Ninety patients with vitiligo having more or less bilaterally symmetrical lesions on the face, trunk or limbs and receiving narrowband UVB therapy were enrolled for the study and instructed to apply topical placental extract (placentrex) lotion on their vitiligo lesions on the right side of the body. The other side of the body received narrowband UVB therapy alone and served as the control side. The extent of repigmentation achieved was assessed by VASI scoring and compared between the symmetrical lesions present on the two sides at monthly intervals and at the end of study period. Results: Seventy-eight patients with 218 symmetrically distributed lesions, excluding those present on the hands or feet, were evaluated for study results at the end of treatment period. The time to onset of repigmentation as well as the mean NB-UVB dosage required was the same on the two sides. The mean repigmentation achieved was 63% (VASI score of 3.69) on the right (placental extract) sided lesions in comparison with 62% (VASI score of 3.60) on the left (control) sided lesions. Greater than 90% repigmentation was achieved in 70 symmetrical lesions in 24 patients. Of these 70 lesions, 39 were located on the right side of the body while 31 belonged to the left side of the body. Conclusions: Addition of the topical placental extract was seen to have a modest but a statistically insignificant effect on the efficacy of NB-UVB therapy in causing repigmentation in vitiligo.

Safety, Efficacy and Limitations of Medical Use of Placental Extract

About 90% of the ailments nowadays are thought to be due to reactive oxygen species(ROS), and thus the ROS-scavenging effect of the placenta may be effective in these conditions. By controlling the autonomic system, endocrine system, and stimulation of the immune system, the placenta has effects to improve various kinds of illnesses. However, there has not been a sufficient amount of data from systematic research on the therapeutic effectiveness of the placenta, and more attention from physicians and scientists is expected on this field to provide evidence for its usefulness on many intractable diseases, chronic diseases, and cancer. Besides, the placenta can play a role in anti-aging, rejuvenation, and esthetics without significant side effects. Thorough evaluation of the efficacy and the safety is needed to make placenta a promising therapeutic agent.

The Effect of Placental Extract on the Expression of Tyrosinase, TRP-1 and TRP-2 in SK30 Melanoma Cells / 대한피부과학회지

Placental extract is a reservoir of a large number of bioactive molecules. It has been used in skin care cosmetics and soap, it is expected to have skin whitening effect. But, the effect of placental extract on melanogenesis is not clarified yet and there are several conflicting reports. To study the effect of the placental extract on proliferation and melanogenesis of pigment cells, we examined the proliferation and change of melanin amounts and expressions of tyrosinase, tyrosinase-related protein (TRP)-1 and TRP-2 mRNA in SK30 melanoma cells, which were irradiated or not. The results were as follows: 1. The placental extract inhibited the melanogenesis of SK30 melanoma cells. 2. The placental extract showed no significant effect on the proliferation of SK30 melanoma cells. 3. The placental extract showed antimelanogenic effect by inhibiting the synthesis of tyrosinase, TRP-1 and TRP-2 mRNA. 4. The inhibitory effect of placental extract was more significant in UVB-irradiated SK30 melanoma cell lines. In conclusion, this study showed that the placental extract might be a good therapeutic regimens for UV-aggravated pigment disorders including melasma. Henceforth, further investigation is needed to identify and purify the active substance from the crude placental extract.
