This study was carried out to investigate the antidiabetic and antioxidative effect of Lycii fructus in the Streptozotocin(STZ)-induced diabetic rats. The effective fractions were prepared as a form of organic solvents of $CH_{3}(CH_{2})_{4}CH_{3}$ $CHCI_{3}$, EtOAc, BuOH and $H_{2}O$ fractions prepared from the EtOH extract of Lycii fructus and The diabetes were induced by an tail-intravenous injection of STZ with a dose of 45 mg/kg dissolved in citrate buffer. The various fractions of Lycii fructus were orally administrated once a day for 7 days. The contents of serum glucose, and triglyceride in the $CHCI_{3}$ fraction and hepatic lipid peroxidation in the EtOAc, BuOH and $H_{2}O$ fractions treated rats were significantly decreased when compared to those of the STZ-control group In addition, an activity of hepatic GST in the BuOH fraction treated rats was significantly increased compared to that of the STZ-control group. whereas, activities of hepatic catalase, GSH-Px in the BuOH fraction treated rats were significantly decreased compared to those of the STZ-control group. Meanwhile, The content of hepatic glycogen and avtivity of hepatic glucokinase in $CHCI_{3}$ fraction treated rats were significantly increased, but activity of glucose-6-pase was significantly decreased in the $CHCI_{3}$ fraction treated rats. In conclusion, these results indicated that the BuOH fraction of Lycii fructus was effective for the antioxidation, and also the $CHCI_{3}$ fraction of Lycii fructus was effective for the antidiabetes in the STZ-induced diabetic rats.

Lycii Fructus (LF) has been reported to possess various biological activities. In this study, we investigated the anti-inflammatory and anti-allergic effects of LF extract in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells and rat peritoneal mast cells(RPMC). LF extract inhibited NO production and the expressions of inducible NO synthase (iNOS) mRNA and enzyme protein, determined by Griess reactions, RT-PCR and Western blotting, respectively, in LPS-stimulated RAW 264.7 macrophages cells. LF extract significantly inhibited histamine release in compound48/80 stimulated rat peritoneal mast cells compared with the compound48/80 only treated cells. It is suggested that the LF extract can improve the inflammation status that involves the histamine release.

The aim of this study was to evaluate the effect of Lycii fructus (LF) on serum lipid and the collagen content of the connective tissues in ovariectomized rats. From day 2 until day 37 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rat (Sham), ovariectomized control rat (OVX-control), and ovariectomized rats supplemented with the LF 50mg/kg bw/day (OVX-LF). The LF ethanol extract were orally administrated 1ml per day. Body weight gain was not significantly different in groups. Although total-cholesterol and triglyceride were increased in the ovariectomized control, supplementation with the LF extract decreased the levels. Moreover, the serum HDL-cholesterol levels were significantly increased after supplementation with the LF extract(p<0.05). Supplementation with the LF extract prevented a decrease in the collagen level in bone and cartilage tissues. These results are consistent with the conclusions based on the estrogenic activities of LF. Therefore, it may be used to possibly improve the quality of life in menopausal women.

Objectives : This study aimed to compare the anti-diabetic efficacy of Lycii Radicis Cortex (Lycium chinense Mill.) and Corni Fructus (Cornus officinalis) on streptozotocin (STZ)-induced diabetes in rats. Methods : Male Sprague-Dawley rats were divided into four groups; normal, STZ-control, Lycii Radicis Cortex extract-administrated group (LRC) and Corni Fructus extract-administrated group(CF). Diabetes in rats was induced by intraperitonal injection with streptozotocin (STZ) at doses of, 30 mg/kg (body weight) for 5 days (once per a day). STZ-induced diabetic rats were orally administrated LRC and CF extract daily for 4 weeks at doses of 300 mg/kg. Fasting blood glucose, total cholesterol (TC), triglyceride (TG), blood urea nitrogen (BUN) and creatinine were measured in sera of rats. Histopathological changes of kidney, liver and lung tissues were observed by microscope after H&E staining. Results : There were no differences in body and kidney weights, food intake and water intake in LRC- and CF-administrated groups compared with STZ control group. However, glucose, TC and TG levels in serum were significantly decreased in LRC-administrated groups compared with STZ-control group. In histopathological analysis of kidney, liver and lung, both LRC- and CF-administrated groups showed the inhibition of morphological damage. Conclusions : These results suggest that LRC and CF have a biological action on STZ-induced diabetes in rats via decreasing the serum TG and TG levels and may protect the morphological changes of kidney, liver and lung.

Objective : The purpose of this study was to investigate the synergistic effect of Angelicae gigantis Radix (AG) and Lycii fructus (LF) ethanol extracts on skin-whitening effects. Method : LFAG extracts were prepared by extracting with 80% ethanol. The efficacy of LFAG was judged by measurement of cell viability, tyrosinase activity, melanin production, tyrosinase and microphthalmia-associated transcription factor (MITF) expression in B16F10 murine melanoma cells by lipopolysaccharides (LPS) treatment. Results : Each extract (LF or AG) inhibited the tyrosinase activity in a dose-dependent manner. The co-treatment of LFAG extracts ($25{\mu}g/mL$ LF plus $25{\mu}g/mL$ AG) markedly suppressed the LPS-induced cellular tyrosine activity, melanin production, tyrosinase and MMP-1 expression in B16F10 murine melanoma cells. These suppressive effects were synergistically increased by their combination. Conclusions : With these observations, we suggest that the extracts from Lycii fructus and Angelica gigantis Radix could be potent natural materials for whitening skin.
