This study was performed to investigate the influence of Chlorella which effected the change of Pb contents, enzyme activity and lipid compounds on the rats fed the beverage involved Pb and the different contented Chlorella added-diets for 18weeks. The rat's weight of 200ppm Pb group was decreased 6.04% and the cause of that was Pb intake. But the rat's weight of Chlorella added-diets +200ppm Pb group was increased 4.02% (p<0.01). When feeding the different(0%, 2%, 5%, 10% ) Chlorella added-diets with the Pb contented beverage to the rats, we could know that the Pb contents accumulated on tissue were decreased to 20.70(0%), 12.88(2%), 14.83 (5%) and 19.56(10%), compared with the quantity of Pb taken in. Total-cholesterol, triglyceride, glucose content and AST, ALT, ALP, LDH enzyme activity in serum were the highest on 200ppm Pb group and those were decreased by the order of different(2%∼5% >10%) Chlorella contents + 200ppmPb group. A significance was recognized on the level of 1%. Therefore, when rats were exposed to Pb, it was thought that the amount of Chlorella intake was adequate on content 2∼5% for reducing the lead toxicity.

In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of $10.74{\pm}0.56%$, ash $9.67{\pm}0.56%$, crude protein $25.24{\pm}1.02%$, and crude fat $2.66{\pm}0.08%$. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

The ethanol extract of the peony root (Paeonia Lactiflora Pall, Paeoniaceae) as well as its major active components including gallic acid and methyl gallate were evaluated for their protective effects against free radical generation and lipid peroxidation. In addition, the protective effects against hydrogen peroxide-induced oxidative DNA damage in a mammalian cell line were examined. The ethanol extracts of the peony root (PREs) and its active constituents, gallic acid and methyl gallate, exhibited a significant free radical scavenging effect against 1,1-diphenyl-2-picryl hydrazine (DPPH) radical generation and had an inhibitory effect on lipid peroxidation, as measured by the level of malondialdehyde (MDA) formation. The PREs did not have any pro-oxidant effect. They strongly inhibited the hydrogen peroxide-induced DNA damage from NIH/3T3 fibroblasts, as assessed by single cell gel electrophoresis. Furthermore, the oral administration of 50% PRE (50% ethanol extract of peony root), gallic acid and methyl gallate potently inhibited the formation of micronucleated reticulocytes (MNRET) in the mouse peripheral blood induced by a $KBrO_3$ treatment in vivo. Therefore, PREs containing gallic acid and methyl gallate may be a useful antigenotoxic antioxidant by scavenging free radicals, inhibiting lipid peroxidation and protecting against oxidative DNA damage without exhibiting any pro-oxidant effect.

The major cuticular components have been shown to be synthesized in the epidermis. Therefore, cloning of epidermis-specific genes could yield information to be used to isolate and characterize the enzymes involved in the cuticle biosynthesis. A subtractive cDNA library was prepared from Senecio odorus in which epidermis-specific cDNAs were enriched. Differential screening of the library using epidermal and non-epidermal probes revealed two cDNAs. One of them designated epi425 was identified, based on the sequence homology, as a member of a new class in the LTP gene family and the other clone designated epi23 as a gene encoding an aldehyde decarbonylase. Northern blot analyses showed that epi425 and epi23 cDNAs hybridized with a transcript of about 600 and 2, 100 nucleotides, respectively, from the epidermis but not from the non-epidermal tissues. Further characterization of these clones will provide more information on the mechanism of the cuticle biosynthesis.
