  • Apoptosis of Prunus salicina Lindl. cv. Soldam, which possesses hematopoiesis, osteoporosis prevention, and antimutagenic effects, at different growth stages was evaluated. Cytotoxic effect of acetone extracts of immature fruits against various tumor cell lines was higher than that of mature fruits, particularly in hormone-independent human breast cancer, MDA-MB-231 cell line. Immature fruit extract increased expression level of pro-apoptotic protein Bax and reduced that of anti-apoptotic protein Bcl-2, and stimulated caspase-3 activity in MDA-MB-231 cells. Results suggest immature fruit of P. salicina Lindl. cv. soldam to be natural source for development of functional food and medical agents to prevent human breast cancer.

  • Sulforaphane, an isothiocyanate derived from hydrolysis of glucoraphanin in broccoli and other cruciferous vegetables, was shown to induce phase II detoxification enzymes and inhibit chemically induced mammary tumors in rodents. Recently, sulforaphane is known to induce cell cycle arrest and apoptosis in human canter cells, however its molecular mechanisms are poorly understood. In tile present study, we demonstrated that sulforaphane acted to inhibit proliferation and induce morphological changes of human hepatocarcinoma HepG2 cells. Treatment of HepG2 cells with $10{\mu}M\;or\;15{\mu}M$ sulforaphane resulted in significant G2/M cell cycle arrest as determined by DNA flow cytometry. Moreover, $20{\mu}M$ sulforaphane significantly induced the population of sub-G1 cells suggesting that sulforaphane induced apoptosis. This anti-proliferative effect of sulforaphane was accompanied by a marked inhibition of ryclin A, cyclin 31 and Cdc2 protein. However, the levels of tumor suppressor p53 and Cdk inhibitor p21 mRNA and protein expression were significantly increased by sulforaphane treatment in a concentration-dependent manner. Although further studies are needed, the present work suggests that sulforaphane may be a potential rhemoprevetiveichemotherapeucc agent for the treatment of human cancer cells.

  • Lemon myrtle (Backhousia citriodora) has been identified as one of the plants that are likely to undergo important commercial exploitation. This study was carried out to investigate the anti-inflammatory activities and nitric oxide synthase (iNOS) expression of hot water (LMW) and 80% ethanol (LME) extracts from lemon myrtle leaf in lipopolysaccharide-induced (LPS) RAW 264.7 cells. The total phenol content of LMW and LME was 207.44 and $331.54{\mu}g$ tannic acid equivalents (TAE)/mg, respectively (p<0.01). DPPH radical scavenging activities of LMW and LME were remarkably increased in a dose-dependent manner, and were about 90.69% and 92.50% at 0.5 mg/ml, respectively. Superoxide dismutase (SOD) activities of LMW and LME were 106.22% and 103.58% at 1 mg/ml, respectively. The highest activity (91.03%) of nitrite-scavenging was observed for LME at 1 mg/ml at pH 1.2, while the activity for LMW was about 81.03% under the same conditions (p<0.05). Anti-inflammatory effect was examined in LPS stimulated RAW 264.7 cells. Nitric oxide (NO) production were reduced to 35.41% and 78.39% by addition of LMW and LME at 0.5 mg/ml, respectively (p<0.05). LMW and LME reduced protein expression of inducible nitric oxide synthase (iNOS) in a dose-dependent manner (p<0.05). These results, we conclude that lemon myrtle may be a highly valuable natural product owing to its high-quality functional components as well as its anti-oxidant and anti-inflammatory activities.

  • The aim of this study was to investigate the potential effects of extracts from silkworm Bombyx mori L. fermented with Bacillus subtilis KACC 91157 at levels of 5%(v/w) and 10%(v/w) in Sprague-Dawley rats intoxicated with 1%(w/w) orotic acid (OA) for 10 days. The rats were divided into a normal group (N), a control group (C: OA), and treatment groups (SP10: OA + 10% extracts from B. mori L.; BSP5: OA + 5% extracts from B. mori L. fermented with B. subtilis KACC 91157; BSP10: OA + 10% extracts from B. mori L. fermented with B. subtilis KACC 91157). Serum activities of aspartate aminotransferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) increased following OA feeding, but the rise was slightly reduced by administration of BSP10. The total lipid, free fatty acid, phospholipid, total cholesterol, and triglyceride contents in serum were significantly lower in the OA treatment groups than in the N group. However, the contents slightly increased following the administration of BSP10. Glutathione concentrations in liver and serum were reduced in the OA-induced fatty liver, but they increased following the administration of BSP10. Hepatocytes in the OA-induced fatty liver contained numerous large droplets. However, SP10, BSP5, and BSP10 feeding prevented OA-induced lipid droplet accumulation in hepatocytes. Accordingly, extracts from silkworm powder fermented with B. subtilis could be an ideal material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.

  • The objective of this study was to identify pulmonary functional variations in relation to postural changes, lapse after changing position, and the use of abdominal band in the cervical cord injured. The subjects of this study were 19 quadriplegic patients who had been admitted to the department of the Rehabilitation Hospital, College of Medicine, Yousei University, from April, 1997 through May 3, 1997. A spiroanalyzer was used to measure pulmonary function in supine, standing, time after changing position, and recording to the position, application method, and tightness of the abdominal band. The data were analyzed by the repeated measure one-way ANOVA, and Wilcoxon signed rank test. The findings were as follows: 1. All phase of the patients' pulmonary function improved significantly in supine posture in contrast to standing (vital capacity by $0.46{\ell}$ and expiratory reserve volume by $0.09{\ell}$). 2. The longer the time lapsed from supine posture to standing, the patient's expiratory reserve volume, maximum ventilation volume, vital capacity, and forced expiratory volume increased. 3. When the patient lay in supine position, the maximum ventilation volume, vital capacity, and the forced vital capacity increased then the center line of the abdominal band was placed along iliac crest; on the other hand, when the patient was standing, placing the bottom line of the abdominal band along iliac crest increased the maximum ventilation volume, vital capacity, and forced expiratory volume. 4. In placing the abdominal band in the patients, leaving space between the top and bottom lines of the band helped increased in maximum ventilation volume, vital capacity, and forced vital capacity for patient in supine as well as in standing. 5. When placing the abdominal band to patients in supine posture, reducing the length of the band by 2.5% along the patient's waist line increased the patients' vital capacity, while reducing the length by 10% to patients in standing increased the maximum ventilation volume. The abdominal band should be placed in such a way that the bottom part of the band should be more tightly fastened while leaving enough room for a hand to be placed in between the body and the band for the top part of the hand. It should also be noted that in a supine position, the bottom line of the band should be placed along the iliac crest, while in standing, the center line should be placed along the iliac crest. The length of the band should also be reduced by 2.5% of the waist line in supine position, and in standing, the length should be reduced by 10%. It should also be noted that the pulmonary function of the patients should be measured at least 10 minutes after one position change.

  • Piperine is an alkaloid-amine found in pepper and has been reported to have anticarcinogenic properties. To explore the possibility that piperine has cancer chemopreventive and chemotherapeutic effects in colon cancer, we examined whether piperine inhibits the growth of HT-29 human colon cancer cells and investigated the mechanisms for this effect. Cells were cultured with various concentrations ($0{\sim}40{\mu}M$) of piperine. Piperine decreased the cell viability and induced apoptosis of HT-29 cells. Western blot analysis of total cell lysates revealed that piperine decreases the protein levels of Bcl-2, Mcl-1, and intact Bid but increases Bik levels. Piperine increased the percentage of cells with depolarized mitochondrial membrane, and the release of cytochrome c into cytoplasm. Piperine induced the cleavage of poly (ADP-ribose) polymerase and caspases 8, 9, 7, and 3 and increased the Fas levels. In addition, piperine significantly decreased the protein levels of survivin. The present results indicate that piperine inhibits the growth of HT-29 colon cancer cells by the induction of apoptosis, which may be mediated by its ability to change the Bcl-2 family proteins, increase the activation of caspases, and decrease survivin levels. Overall, our findings suggest that piperine has cancer chemotherapeutic effects in colon cancer.

  • The objective of this study was to determine the antioxidant activities of rice bran extracts by three different extraction methods. Rice bran was extracted by solvent extraction, saponification extraction, and supercritical fluid extraction. The antioxidant activities of the rice bran extracts were determined based on ABTS and DPPH radical scavenging activities, reducing power, and lipid peroxidation inhibitory activity. The unsaponifiable matter (USM) extracted by the saponification method showed higher ABTS (671.7 mg Trolox equivalent antioxidant capacity (TEAC)/g) and DPPH (330.7 mg TEAC/g) radical scavenging activities as well as reducing power ($A_{700}=1.14$) than those of the solvent extract (ME) and supercritical fluid extract (SFE). Inhibitory effect on lipid peroxidation was higher in USM (68.7%) and SFE (75.4%) compared to ME (47.8%). USM indicated relatively higher antioxidant activities compared with those of SFE and ME. These results show that the saponification method for extraction of USM from rice bran extracted was the most effective method for enhancement of antioxidant activity. In addition, these extracts from rice bran could be used as functional ingredients in the food industry.

  • The purpose of the present study was to determine the effect of a 4 week course of Cox distraction manipulation (CDM) combined with therapeutic modalities on the treatment of patients with L4-5 herniated nucleus pulposus (HNP). A total of 15 patients with L4-5 HNP (mean age, 37.76 years; age range 20-50years) participated in the study. A 4 week course of CDM combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and three times per week for two additional weeks. The entire treatment consisted of 18 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and oswestry disability index (ODI) at pre-intervention, after two weeks treatment sessions, and at discharge (after 18 treatment sessions) were analyzed. Comparisons of changes in the disc herniation index (DHI) at pre-intervention and at discharge were analyzed using the paired t-test. There were significant improvements in the outcome measures of MS Ibs, SLR test, and ODI score after 2 weeks and 4 weeks sessions of CDM combined with therapeutic modalities as compared with the pre-intervention. However, no significant different pre-test and post-test DHI. CDM combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with L4-5 HNP.
