  • 1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) has recently been synthesized and characterized to have an anti-inflammatory activity through the inhibition of the production of nitric oxide. In the present study, adverse effects of FPP-3 on hepatic functions were determined in female BALB/c mice. When mice were administered with FPP-3 at 125, 250 or 500 mg/kg for 7 consecutive days orally, FPP-3 significantly increased absolute and relative weights of liver with a dose-dependent manner. In addition, FPP-3 administration dramatically increased the hepatotoxicity parameters in serum at 500 mg/kg, in association of hepatic necrosis. FPP-3 significantly induced several phase I enzyme activities. To elucidate the possible mechanism(s) involved in FPP-3 induced hepatotoxicity, we investigated the hepatic activities of free radical generating and scavenging enzymes and the level of hepatic lipid peroxidation. FPP-3 treatment significantly elevated the hepatic lipid peroxidation, measured as the thiobarbituric acid-reactive substance, and the activity of superoxide dismutase. Taken together, the present data indicated that reactive oxygen species might be involved in FPP-3-induced hepatotoxicity.

  • Various beneficial effects have been described for fermented papaya preparation (FPP: SAIDO-PS501) based on its anti-oxidative and anti-inflammatory functions. The present study was designed to determine the effects of FPP on carcinogenesis in vivo, and immunomodulatory function in vitro. Mice were injected with RL male 1 cells subcutaneously or 3-methylcholantherene (MCA) intravenously to induce cancer and orally or intraperitoneally treated with FPP solution. Human peripheral blood mononuclear cells (PBMC) were obtained from healthy volunteers and patients with atopic dermatitis, treated with FPP, and subjected to measurement of cytokine production and changes in Foxp3-expressing regulatory T cell (Treg) stimulated with phytohemagglutinin (PHA). Administration of FPP suppressed tumor size and the incidence of malignancy. In vitro, treatment of PBMC with FPP induced IL-$1{\beta}$, $TNF{\alpha}$ and $IFN{\gamma}$ production. Moreover, FPP suppressed proliferation of PHA-stimulated Foxp3-expressing Treg. These results suggest that FPP has chemotherapeutic properties.

  • 1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) has recently been synthesized and characterized to have an anti-inflammatory activity through the inhibition of the production of nitric oxide and tumor necrosis factor-$\alpha$. In the present study, adverse effects of FPP-3 on immune functions were determined in female BALB/c mice. When mice were administered orally with FPP-3 at 125, 250 or 500 mg/kg for 7 consecutive days, FPP-3 suppressed the number of antibody-forming cells and reduced thymus weight at 500 mg/kg. In addition, FPP-3 administered mice exhibited reduced splenic cellularity and numbers of splenocyte subsets, such as $CD3^+$ cells, $CD3^+CD4^+$ cells, $CD3^+CD8^+$ cells and macrophages. IL-4 mRNA expression was significantly suppressed by FPP-3 treatment. Moreover, the number of $CD4^+IL-4^+$ cells was reduced following the treatment of mice with 500 mg/kg of FPP-3. These results suggested that FPP-3 at 500 mg/kg might be immunotoxic, and that FPP-3-induced immunotoxicity might be mediated, at least in part, through the inhibition of cytokine production, such as IL-4.

  • Previously, we have shown that 1-furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) has an anti-inflammatory activity in a rat paw-edema model. In the present study, we investigated an inhibitory effect of FPP-3 on the tumor necrosis factor (TNF)-${\apha}$-induced inflammatory cytokine response in HT-29 human colon epithelial cells. Treatment with FPP-3 significantly prevented the TNF-${\apha}$-induced attachment of leukocytes to HT-29 colon epithelial cells, which is one of the pathologic hallmarks in colon inflammation. The effect of FPP-3 was markedly superior than that of 5-aminosalicylic acid (5-ASA), a commonly used drug for the treatment of inflammatory bowel disease (IBD). The pretreatment with FPP-3 inhibited TNF-${\apha}$- induced monocyte chemoattractant protein (MCP)-1, interleukin (IL)-8 mRNA expressions. In addition, FPP-3 significantly suppressed TNF-${\apha}$-induced nuclear factor (NF)-${\kappa}B$ transcription activity. These results demonstrate that FPP-3 modulates intestinal inflammation via suppressing the NF-${\kappa}B$ dependent expressions of MCP-1 and IL-8, and suggest that FPP-3 may be a valuable agent for the treatment of IBD.

  • This study evaluated the effect of fertilization-promoting peptide (FPP) on fertilizing ability and glycosidase activity in vitro of spermatozoa frozen-thawed in pig, Using chlortetracycline fluorescence analysis, the various glycosidase analyses and the oocyte penetration test, we have obtained evidence that FPP can promote the fertilizing ability and glycosidase activity of frozen-thawed spermatozoa in vitro. When frozen-thawed spermatozoa was washed with different concentrations of FPP, there were significantly (P<0.05) more acrosome-reacted in medium with 100 nM than 0, 50, 200 and 400 nM. The penetration rates were also highest in medium containing with 100 nM FPP (P<0.05). On the other hand, the $\beta$-N-acetylglucosaminidase activity was at least twofold higher than other glycosidase. In same glycosidase, however, there were no difference in medium with different concentrations of FPP In another experiment, spermatozoa preincubated in medium with or without FPP for 0, 1, 2, 3 and 4 h were inseminated with oocytes matured in vitro. The percentages of spermatozoa that reached acrosome reaction were affected by preincubation and were higher in medium with that than without FPP. When oocytes were inseminated with spermatozoa preincubated in medium with and without FPP during the different periods, however, penetration rates were decreased with preincubation periods of spermatozoa. On the other hand, when the sperm-oocyte were cultured for 4, 8, 12, 16, 20 and 24 h, the penetration rates were higher in spermatozoa preincubated with that than without FPP and had a tendency to increase as time of culture periods. However, The activities of $\alpha$-fucosidase, $\alpha$ -mannosidase, $\beta$-galactosidase and N-acetyl- $\beta$-D-glucosaminidase were higher in medium with that than without FPP regardless of periods of sperm preincubation and sperm-oocyte culture. These results suggest that FPP may play a positive role in promoting of sperm function and glycosidase activity in vitro in pig.

  • In this study, functionalized poplar powder (FPP) was used as a support material for the immobilization of enoate reductase (ER) and glucose-6-phosphate dehydrogenase (GDH) by covalent binding. Under optimal conditions, the immobilization efficiency of ER-FPP and GDH-FPP was 95.1% and 84.7%, and the activity recovery of ER and GDH was 47.5% and 37.8%, respectively. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analysis indicated that FPP was a suitable carrier for enzyme immobilization. ER-FPP and GDH-FPP exhibit excellent thermal stabilities and superior reusability. Especially, ER-FPP and GDH-FPP enable the continuous conversion of 4-(4-Methoxyphenyl)-3-buten-2-one with $NAD^+$ recycling. While the immobilization strategies established here were simple and inexpensive, they exploited a new method for the immobilization and application of ER and its cofactor recycling system.

  • The effects of orally administered fermented porcine placenta (FPP) and its major dipeptides, L-Leucyl-Glycine (Leu-Gly) and Glycyl-L-Leucine (Gly-Leu), on UVB-induced wrinkle formation of the skin in hairless mice was studied. Treatment with FPP, Leu-Gly or Gly-Leu increased type I procollagen synthesis and decreased MMP-1 (matrix metalloproteinase-1) in human dermal fibroblast cells (HDF-N). Hairless mice were also exposed UVB irradiation three times a week and fermented porcine placenta extract (FPP), Leu-Gly and Gly-Leu was administered once a day for eight weeks. Daily intake of FPP, Leu-Gly and Gly-Leu for eight weeks decreased wrinkles, erythema and thickness of the skin and increased skin hydration and synthesis of collagen relative to a UVB-control. Moreover, FPP, Leu-Gly or Gly-Leu intake decreased the expression of MMP-3 and MMP-13 mRNA levels and inhibited activation of MMP-2 and MMP-9 induced by UVB irradiation in hairless mice skin. These results suggest that major dipeptides of the placenta, Leu-Gly and Gly-Leu have the potential for use as a functional food ingredient with anti-wrinkling properties.

  • Purpose: To determine the effect of the Fall Prevention Program(EPP) on gait, balance and muscle strength in elderly women at a nursing home. Method: The subjects of this consisted of 38 elderly women between the ages of 70 to 89 years living at a nursing home located in Seoul. Each of the experimental group and control group was composed of 19 subjects. The subjects in experimental group have participated in FPP for the 8 weeks which consisted of exercise, education and foot care. They started to exercise for 40 minutes per session, 3 sessions a week during the 1st week at 40% of age adjusted maximum heart rate. From the 2nd week to the 4th week, they increased the duration of exercise to 50 minutes per session and the intensity to 60% of age-adjusted maximum heart rate. They participated in 50 minutes at 60% of age-adjusted maximum heart rate from the 5th week to the 8th week. Each exercise session consisted of 10 minutes of warming-up exercise, 30 minutes of conditioning exercise and 10 minutes of cooling-down exercise. They participated in education for 20 minutes per week from the 1st week to the 4th week. Then they participated in a 30-minute foot care program per week from the 5th week to the 8th week. Gait, balance and muscle strength for each subject were measured before and after FPP. Gait was evaluated by step length, step width, gait speed and walking distance. Balance was measured by the duration of standing on one leg with their eyes closed and open each, and a get-up and go test. Grip strength was measured by hand dynamometer. Hip extensor and flexor strength, knee extensor and flexor strength and ankle plantarflexor and dorsiflexor strength were measured by manual muscle tester. Data was analyzed using SPSS form Windows. t-test and Chi square test were utilized as a homogeneity test. Repeated measure ANOVA was used to test the effect of FPP. Result: 1) Step width significantly decreased, and step length, gait speed and walking distance significantly increased in the experimental group compared with the control group after FPP(p<0.005). 2) There was no significant change in standing time on one leg with their eyes closed after FPP. The standing time on leg with their eyes open and the time of "get-up and go" significantly decreased in the experimental group compared with the control group after FPP(p<0.005). 3) Muscle strength-grip strength, hip extensor and flexor strength-significantly increased in the experimental group compared with the control group after FPP(p<0.005). 4) There was no significant difference of frequency of fall between the experimental group and control group during the period of FPP. Conclusion: These results suggest that FPP can increase gait, balance and muscle strength of elderly women at a nursing home.

  • This study was to examine whether the in vitro friability, motility and intact acrosome of frozen-thawed bovine and human sperm can be improved by adding Pentoxifylline (PF) or Fertilization Promoting Peptide (FPP). Human semen was frozen ultra-rapidly using Test yolk-buffer (TYB) freezing medium. Additive (PF, FPP) effects in frozen-thawed bovine and human sperm were analyzed by microscopic count for sperm motility and coomassie brilliant blue staining method f3r sperm acrosome intact. The in vitro motility of frozen-thawed bovine sperm with 5 mM PF treatment group (50.0%) was significantly higher than that of control (34.0%) (P<0.05). In the frozen-thawed bovine sperm was examined, the intact acrosome rate of 50 nM FPP treatment (49.0%) was significantly higher than those of control (30.0%) and 25 nM FPP (38.0%) treatment groups (P<0.01). In human semen, when in vitro motility of sperm with PF addition prior to freezing was examined, the result of 5 mM treatment group (51.0%) was significantly higher than those of control and 2.5 mM treatment group (39.0, 40.0%) (P<0.01). In addition, 50 nM (75.5%) FPP adding in all treatment procedures for human semen freezing (before freezing, freezing and after thawing) was significant effect on maintenance of the sperm intact acrosome percentage (control: 45.0; 25 nM: 53.0; 100 nM: 68.0%) (P<0.01). Also, the intact acrosome rate of human sperm with FPP (65.0%) was significantly higher than that with PF (43.0%) (P<0.05), although sperm motility was slightly higher in PF treatment group. These results suggest that improved sperm motility and intact acrosome of frozen thawed bovine and human sperm can be obtained by addition of PF or FPP, and that the enhanced in vitro viability, motility and intact acrosome can be obtained by addition of FPP in all semen freezing procedures.

  • Objective: This study has been carried out to evaluation the effect of fertilization promoting peptide (FPP) on the kinematic parameters, capacitation and acrosome reaction of the frozen-thawed human spermatozoa. Methods: After FPP treatment, we examined kinematic parameters, capacitation and acrosome reaction, using the methods of computer-aided sperm analysis (CASA) and chlortetracycline (CTC) fluorescence analysis. Results: We have obtained the evidence that FPP can promote the capacitation and inhibit the spontaneous acrosome reaction of frozen-thawed human spermatozoa in vitro. FPP ($25{\sim}100$ nM) induced a significant increase in the proportion of B-pattem capacitated spermatozoa, and a significant decrease in the proportion of F-pattem uncapacitated ones without significant stimulation of acrosomal exocytosis. In the kinematic parameters treatment, FPP treated groups maint3ined higher LIN, BCF and STR than those of control. The VAP, VSL, VCL and ALH were not different. Therefore it is suggested that FPP in human seminal plasma may play a positive role in promoting human sperm function.
