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.

국내에서 선별 육종된 불로 구기자의 처리방법에 따른 간기능 보호효과를 측정하기 위하여 사염화탄소$(CCl_4)$ 투여로 급성 간독성을 유발시킨 흰쥐를 대상으로 연구하였다. 건조구기자 추출물(DFE), 볶은 구기자 추출물 (RFE), 그리고 생과즙(FFE)을 경구 투여한 결과 군간의 체중증가량은 차이를 나타내지 않았다. 한편, 체중 100 g 당 간 무게는 처리조건에 관계없이 구기자 추출물 및 생과즙 투여군이 유의적으로 낮은 간 무게를 나타내었다(p<0.01). 이것은 구기자 추출물과 생과즙 섭취가 $CCl_4$ 투여에 의한 지방간 형성 또는 간 독성에 의한 간 무게증가를 다소 완화하여준 효과를 나타내는 것으로 판단된다. 사염화탄소$(CCl_4)$ 투여에 의하여 흰쥐의 혈청 GPT 및 GOT 활성과 LDH 활성은 유의적으로 증가하였으나 볶은 구기자 추출물 투여군(RFEC)과 생과즙 투여군(FFJC) 모두 GPT, GOT 활성이 유의적으로 감소되었다. 혈중 총 콜레스테롤 함량은 구기자 추출물과 생과즙 투여군 모두 대조군(CON)과 비교하여 유의적인 증가를 나타내지 않았고 중성 지방함량은 대조군에 비해 유의적인 증가를 나타내었다(p<0.05). 간 조직의 MDA 함량과 GST, cytochrome P-450 활성 결과로 보아 구기자 추출물과 생과즙을 섭취 시 사염화탄소에 의한 독성을 완화시키는 것으로 나타났다. 따라서 이러한 모든 결과를 종합해 볼 때, 구기자 추출물과 생과즙은 $CCl_4$ 투여로 인한 지질 과산화, 지방변성, 간 세포 괴사 등을 억제 시키는 간 독성 보호 효과가 있는 것으로 생각된다.

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.

두 품종 (청양재래, 명안)의 구기자나무 (Lycium chinense Mill.) 유식물체를 자엽하배축의 자엽 일부분만 남기고 절단 후, 절단면이 1.0 mg/L zeatin이 첨가된 MS배지에 접하도록 하여 암소에서 3주 배양한 후 명소로 옮겨 배양하였을 때 자엽하배축 절단면으로부터 부정아가 고빈도 (80% 이상)로 유도되었다. 그러나 자엽하배축절편을 암소에서 전 배양하지 않고, 명소에서만 배양 하였을 경우 부정아는 유도되지 않았다. 자엽하배축 절단면에서 유도된 부정아를 분리하여 1.0 mg/L IAA가 함유된 발근배지에서 4주간 배양하여 뿌리를 유도하였다. 잎과 뿌리가 잘 발달한 소식물체는 화분에 옮겨 키웠을 때 정상적인 형태의 재분화 식물체로 성장하였다.

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.
