Astragalus membranaceus Bunge (黃?), Atractylodes macrocephala Loidz (白朮), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子), Ligustrum lucidum Ail (女貞子) are Herbs that are frequently used in a lot of prescriptions to reduce the side effects of anti-cancer therapies, especially like chemotherapy and radiotherapy. The radioprotective and hemopoietic effects of these Herbs on BALB/c splenocytes and bone marrow cells are measured. In order to evaluate the Hemopoietic effects, Thymidine uptakes and secretion of colony stimulating factors(CSFs) of splenocytes and myelocytes treated with herbs were measured. Radioprotective effects were accessed by the method of immunocompetence of murine lymphocytes cultured with herbs before irradiation and with LPS, ConA after irradiation. The results are as follows. 1. The orders of Proliferative effects of herbs on splenocytes were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸). Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all. At Optimal concentration, the proliferation ratios of herb-treated splenocytes compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 44.3, Astragalus membranaceus Bunge (黃?) 17.7, Angelica sinensis(Oliv) Kiels (當歸) 10, Lycium chinense Mill (枸杞子) 6.4, Ligustrum lucidum Ait (女貞子) 2.0.(p<0.05) 2. When splenocytes were cultured during different periods, Atractylodes. macrocephala Loidz (白朮) and Astragalus membranaceus Bunge (黃?) showed the higest proliferation on 3th day, Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) on 4th day,(p<0.05) and Ligustrum lucidum Ait (女貞子) until 5th day but with no significant increase. 3. The orders of Proliferative effects of herbs on Bone Marrow(BM) cells were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus memhranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) and Ligustrum lucidum Ait (女貞子), the lowest of all too. At Optimal concentration, the proliferation ratios of herb-treated BM cells compared to non-treated ones were like these. Atractylodes macrocephala Loidz (白朮) 21.7, Astragalus membranaceus Bunge (黃?) 9.9, Angelica sinensis(Oliv) Kiels (當歸) 4.9, Lycium chinense Mill (枸杞子) 2.3, Ligustrum lucidum Ait (女貞子) 1.4(p<0.05). 4. The secretion ratio of colony stimulating factors(CSFs) of each herb-treated group, compared to control, was Atractylodes macrocephala Loidz (白朮) 9.4, Astragalus membranaceus Bunge (黃?) 9.0, Angelica sinensis(Oliv) Kiels (當歸) 4.4, Lycium chinense Mill (枸杞子) 3.8 (p<0.05) but no significant increase in Ligustrum lucidum Ait (女貞子). 5. The mitogen(ConA, LPS) stimulated-lymphocytes cultured with each herb before irradiation of 1-3 Gy showed more enhanced proliferation than control(p<0.05). When compared to each non-irradiated group of all groups, the orders of percentage increase of irradiated group were Atractylodes macrocephala Loidz (白朮), the higest of all, Astragalus membranaceus Bunge (黃?), Angelica sinensis(Oliv) Kiels (當歸), Ligustrum lucidum Ait (女貞子), Lycium chinense Mill (枸杞子). Each percentage showed significant enhancement compared to control group(p<0.05). According to the results, Atractylcdes macrocephala Loidz (白朮), Astragalus membranaceus Bunge (黃?) are suggested to be the most effective hemopoietic and radioprotective herbs, and Angelica sinensis(Oliv) Kiels (當歸), Lycium chinense Mill (枸杞子) the next, but Ligustrum lucidum Ait (女貞子) showed lower effects than expected.

Hepatoprotective effects of Bulro Kugi (Lycium chinense Mill) fruit extracts on $CCl_4-administered$ rats were investigated in vivo. Administration of $CCl_4$ increased plasma glutamic oxalacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and lactate dehydrogenase (LDH) activities, induced lipid peroxidation as measured by malondialdehyde (MDA) content of rat liver, and significantly increased liver weight. Feeding of B. Kugi (Lycium chinense Mill) slightly increased body weight gain, although not significantly different from normal group. B. Kugi (Lycium chinense Mill) fruit extracts reduced blood cholesterol level and inhibited $CCl_4-induced$ increases of plasma GPT, GOT, and LDH activities, whereas increased contents of MDA and cytochrome P-450, and GST activity in liver tissue of $CCl_4-administered$ rats. Roasted B. Kugi (Lycium chinense Mill) fruit extract showed highest hepatoprotective effect among samples tested. These results suggest water extracts of B. Kugi (Lycium chinense Mill) fruit possess promising hepatoprotective activity against $CCl_4-induced$ hepatic damage in rats.

The strength of the connecting joint of boxthorn(Lycium chinense Mill) fruits to tree twigs was determined experimentally at several pulling angles(0$^{\circ}$, 15$^{\circ}$, 30$^{\circ}$,45$^{\circ}$and 60$^{\circ}$) and at different harvesting seasons from August to November 1999 using an universal testing machine. The detachment force of mature fruits of boxthorn decreased as the pulling angle increased and varied with the harvesting season. The detachment force however did not gradually decreased as the harvesting season advanced due to difference of maturity of fruits from one harvesting season to another. Among three varieties of boxthron Cheongyang gugija Cheongyang native and Cheongyang ＃2, the maximum detachment force was 1.24 N at the pulling angle of zero degree. The highest detachment forve(1.29 N) of mature fruits of boxthorn appeared at the harvesting season of August, 1999.

Detachment rate of mature fruits of the Lycium chinense Mill with various frequency, amplitude, and shaking time using an experimental vibratory system was analyzed. The experimental vibratory system was designed such that the frequency, amplitude, and shaking time could be controlled easily. The detachment rate increased as the frequency increased at constant amplitude and increased as the amplitude increased at constant frequency. The contents of the detached immature fruit, however, also increased as the frequency and amplitude increased, which was undesirable for the detachment efficiency considering the only mature 900 rpm and amplitude of 35 m for the shaking time of three seconds.

To establish high frequency shoot formation from two cultivars (Cheongyangjaerae and Myungan) of boxthorn (Lycium chinense Mill.), hypocotyl segments with cotyledons from seedlings were used as explants. High frequency adventitious shoot formation (more than 80%) were obtained from hypocotyl segments with cotyledon on MS medium supplemented with 1.0 mg/L zeatin, when precultured for 3 weeks under dark conditions followed by transfer to light conditions. But there was no shoot induction in the explants cultured without preculture under dark conditions. Roots were induced from the shoots when transferred to rooting medium supplemented with 1.0 mg/L IAA for 4 weeks. Regenerated plantlets were grown to normal mature plants in soil.

This study was conducted to develop a functional feed additive for pig with spent $Lycium$ $chinense$ Mill fruit. We investigated the optimum conditions for the extraction of polyphenol from spent $Lycium$ $chinense$ Mill using methanol. Methanol concentration as a solvent for extraction, extraction time and the volume of solvent per a gram of solid (ground spent Lyceum chinense Mill) were selected as parameters. Three levels of parameters were configured according to Box Behnken experiment design, a fractional factorial design, and total 15 trials were employed. Total polyphenol concentration from each trial was used as response from experiment system and effects of parameters on total polyphenol extraction efficiency were determined using response surface model. As a result, all terms in analysis of variance, regression ($p$ = 0.001), linear ($p$ = 0.002), square ($p$ = 0.017) and interaction ($p$ = 0.047) was significant and adjusted determination coefficient ($R^2$) was 94.7%. Total polyphenol extraction efficiency was elevated along increased methanol content and decreased solvent to solid ratio. However extraction time did not affect the efficiency. This study provides a primary information for the optimum extraction conditions to maximize total polyphenol recovery from spent Lycium chinens Mill fruit and this result could be applied to re-use of argo-industrial by-products and to develop of functional feed additives in organic farming.

A $CHCl_3$:MeOH extract of the fruit of Lycium chinense Mill. (Solanaceae) was found to afford significant protection against carbon tetrachloride-induced toxicity in primary cultures of rat hepatocytes. Subsequent activity-guided fractionation resulted in the isolation of zeaxanthin and zeaxanthin dipalmitate as antihepatotoxic components. Incubation of injured hepatocytes with zeaxanthin dipalmitate reduced the levels of glutamic pyruvic transaminase (GPT) and sorbitol dehydrogenase (SDH) released from damaged cells to 60.5% and 76.3% of those released from untreated controls, respectively. Zeaxanthin also reduced the levels of GPT and SDH to 68.5% and 61.3% of the levels of those released from the untreated contro. The results confirm the hepatoprotective activities of zeaxanthins. Antihepatotoxic activities of zeaxanthins are comparable to that of silybin.
