  • We investigated effects of methanol extract of Aloe vera on anticancer drugs(cisplatin, mitomycin C, 5-fluorouracil)-induced growth inhibition in p388, L1210, HCT-15, SK-HepG-1 as cancer cell lines and mouse splenocytes as a normal cell by MTT assay, respectively. We also examined the effects of aloe extract and mitomycin C on the mitogen(Con, A, LPS)-induced splenocyte proliferation. Aloe extract(0.25 mg/m , 1.25 mg/m , 2.5 mg/m , 5.0 mg/m ) showed dose-dependently selective cytotoxicity against the cancer cell lines. In contrast, Aloe extract increased the growth and proliferation of the normal mouse splenocytes. The combination of aloe extract with anticancer drugs showed an additive effect for the cytotoxicity against cancer cell lines. However, that combination reduced clealy the anticancer drugs-induced toxicity against the normal mouse splenocytes.

  • Background: In recent years, there has been considerable research on recycling of agro-industrial waste for production of bioactive compounds. The food processing industry produces large amounts of citrus peels that may be an inexpensive source of useful agents. Objective: The present work aimed to explore the phytochemical content, antioxidant, anticancer, antiproliferation, and antigenotxic activities of lemon, grapefruit, and mandarin peels. Materials and Methods: Peels were extracted using 98% ethanol and the three crude extracts were assessed for their total polyphenol content (TPC), total flavonoid content (TFC), and antioxidant activity using DPPH (1, 1-diphenyl-2-picrylhydrazyl). Their cytotoxic and mitogenic proliferation activities were also studied in human leukemia HL-60 cells and mouse splenocytes by CCK-8 assay. In addition, genotoxic/antigenotoxic activity was explored in mouse splenocytes using chromosomal aberrations (CAs) assay. Results: Lemon peels had the highest of TPC followed by grapefruit and mandarin. In contrast, mandarin peels contained the highest of TFC followed by lemon and grapefruit peels. Among the extracts, lemon peel possessed the strongest antioxidant activity as indicated by the highest DPPH radical scavenging, the lowest effective concentration 50% ($EC_{50}=42.97{\mu}g\;extract/mL$), and the highest Trolox equivalent antioxidant capacity (TEAC=0.157). Mandarin peel exhibited moderate cytotoxic activity ($IC_{50}=77.8{\mu}g/mL$) against HL-60 cells, whereas grapefruit and lemon peels were ineffective anti-leukemia. Further, citrus peels possessed immunostimulation activity via augmentation of proliferation of mouse splenocytes (T-lymphocytes). Citrus extracts exerted non-cytotoxic, and antigenotoxic activities through remarkable reduction of CAs induced by cisplatin in mouse splenocytes for 24 h. Conclusions: The phytochemical constituents of the citrus peels may exert biological activities including anticancer, immunostimulation and antigenotoxic potential.

  • This study was performed to investigate the potential of pear (Pyrus pyrifolia) as a immune-modulating functional food by assay of splenocytes proliferation and induction of cytokines (IFN-${\gamma}$, IL-4) in vitro. When mouse splenocytes were exposed to various concentration (0.16, 0.31, 0.63, 1.25, 2.50 mg/ml) of pear methanol extracts (P-M) without mitogens, splenocytes proliferation (SP) was significantly increased. Also, SP to mitogens, concanavalin A (Con A) and lipopolysaccharide (LPS) were significantly increased by P-M when compared with controls. When splenocytes were cultured with P-M in the presence of Con A, cytokine (IFN-${\gamma}$, IL-4) levels in culture supernatant were significantly enhanced in a dose-dependent manner except 2.5 mg/ml when compared with control group. Therefore, our study suggest that the pear has the potential of being an immune-modulating functional food.

  • To investigate the effect of bovine colostral whey fractions on in vitro proliferation of mouse splenocytes, polypeptide fractions were separated from acid whey into 3 fractions depending on molecular weight by ultrafiltration: Fraction I, which contains the polypeptide larger than 10,000 Da, Fraction n, which contains the polypeptide ranging from 1,000 Da to 10,000 Da and Fraction III, which contains the polypeptide smaller than 1,000 Da. Fraction II showed the highest proliferative effect of mouse splenocytes among the colostral whey fractions and this proliferative activity increased in dose dependent manner. Unheated Fraction II and Fraction III showed significantly (p<0.01) higher proliferative effects than others but heated Fraction II showed the highest enhancing effect of mouse splenocyte among heated whey fractions (p<0.01). The supplementation of Fraction II and Fraction m showed greater proliferative effect of mouse splenocytes stimulated by concanavalin A (Con A) than that of whole whey or Fraction L Proliferative effect of mouse splenocytes stimulated by phytohemagglutinin (PHA) was the highest when Fraction II was supplemented Proliferative effect of the colostral whey fractions on mouse splenocytes by stimulation of lipopolysaccharide (LPS) was markedly enhanced by supplementation of Fraction II and Fraction m compared with whole whey and Fraction L It was estimated that colostral whey fraction containing IGF-I positively affected proliferation of mouse splenocyte.

  • Nelumbo nucifera Gaertn has been usedas a traditional remedy and food source in South Korea. It promotes gastrointestinal function and controls blood pressures. Nelumbo nucifera Gaertn water extracts supplement at 5, 10, 50, 100, 250, 500, $1,000{\mu}g/mL$ after a 48 h pre-treatment with the mitogen (ConA or LPS) increased the mouse splenocytes proliferation. Water extract supplement also increased the cytokine production ($IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$), measured by a cytokine ELISA kit. For the result of in vitro study, the proliferation of splenocytes and cytokine production activated by peritoneal macrophages increased when water extracts were supplemented in the range of $50{\sim}500{\mu}L/mL$ concentration. Specifically, the levels of the splenocytes proliferation, $IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$ were the highest at $250{\mu}L/mL$ concentration. This in vitro study suggestedthat supplementation with Nelumbo nucifera Gaertn water extracts may enhance the immune function by regulating the splenocyte proliferation and enhancing the cytokine production activating macrophage in vitro.

  • Chitosan is a depolymerized and partially deacetylated derivative of chitin. We investigated the cytotoxicity of chitosan in cancer cell lines, such as P388, L1210, HCT-15, SK-HepG-1 and mouse splenocytes as a normal cell by MTT assay. To clarify whether chitosan enhances cytotoxicity of anticancer drugs, we also examined the cytotoxicity of combined treatment with chitosan and anticancer drugs, such as cisplatin, mitomycin C, and 5-fluorouracil in cancer cell lines in vitro. Chitosan ($37.5\;{\mu}g/mL,\;75\;{\mu}g/mL,\;112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$) showed concentration-dependent cytotoxicity in the cancer cell lines. In addition, chitosan showed relatively lower cytotoxicity in normal cells than in the cancer cell lines. Particularly, this trend was significant at high doses of chitosan, i.e. $112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$. Thus, these results suggest that chitosan may selectively induce the growth inhibition in cancer cell lines, compared to normal cells. Furthermore. the co-treatment of chitosan and anticancer drugs exhibited an apparant synergistic cytotoxicity in murine lymphoma cell lines, i.e. P388 and L1210 at $37.5\;{\mu}g/mL$ of chitosan rather than at $75\;{\mu}g/mL$ of chitosan, but such phenomenon could not be observed in solid tumor cell lines, i.e. HCT-15 and SK-HepG-1. However, chitosan did'nt reduced the cytotoxicity against normal mouse splenocytes induced by anticancer drugs. Therefore, it is concluded that the combination of chitosan and anticancer drugs might be useful for the cancer chemotherapy.
