Immunological activities of the combined-administration of Acanthopanacis Cortex and Lycii Cortex Radicis were examined in BALB/C mice. The 40% ethyl alcohol extract of Acanthopanacis Corter (AE) or the 40% ethyl alcohol extract of Acanthopanacis Coriex and Lycii Cortex Radicis (ALE) were administered p.o. once a day for 7 days, respectively. AE did not affect the viability of thymocytes, but ALE decreased the viability of thymocytes. ALE enhanced the viability of splenocytes increased by AE. Also, AE enhanced the population of cytotoxic T cell in thymocytes, and ALE enhanced the population of helper T cell compared with AE. Furthermore, AE increased the population of $Thy1^+$ cells in splenocytes, and increased the population of splenic $CD4^+$ cells. In addition, ALE enhanced the phagocytic activity which was decreased by AE ALE decreased the production of nitric oxide increased by AE in peritoneal macrophages. These results suggest that ALE enhance an immune-regulative action of AE.

Objectives : This study was performed to investigate the anti-diabetic effect of the fruit extract of Lycium chinense Mill(Lycii Fructus, LF) on multiple low-dose streptozotocin-induced diabetic rats.Methods : Male Sprague-Dawley rats were divided into three groups; normal, STZ-control, Lycii Fructus extractorally administrated 300 ㎎/㎏ group (STZ-LF). Diabetes was induced in rats by consecutive injection of streptozotocin (STZ) at doses of 30 ㎎/㎏ for 5 days. After 4 weeks, all rats were sacrificed, Fasting blood glucose, total cholesterol (CHO), triglyceride (TG) and HDL-Cholesterol were measured in sera of rats. Histopathological changes of pancreas, kidney, liver and lung tissues were observed by microscope after H&E, Periodic acid-Schiff (PAS) and Masson's trichrome staining. The changes of body weight, blood glucose, and food and water intake were also measured.Results : There were no differences in body, food intake and water intake in LF-administrated groups compared with STZ control group. However, LF extract significantly decreased the levels of serum glucose, CHO, TG and HDL-Cholesterol in diabetic rats. In histopathological analysis of kidney, liver and lung, LF-administrated groups showed the inhibition of morphological damage.Conclusions : These results suggest that LF have a biological action on multi low-dose STZ-induced diabetes in rats via decreasing the serum glucose, TG and TG levels and may protect the morphological changes of kidney, liver and lung.

Effects of Lycii Fructus on primary cultured chicken embryonic brain cells were studied by microscopic observation, determination of the activity of pyruvate dehydrogenase complex (PDHC), and syntheses of protein, RNA and DNA. The brain cells were prepared from the brains or 10-day-old chicken embryos and cultured with a deficient medium. The activity of PDHC in the brain cells cultured with a deficient medium was increased to 1.8 times by the addition of $30\;{\mu}g/ml$ of the total methanol extract of Lycii Fructus. To seek the active fraction, total methanol extract was further fractionated by the polarity. The survival rate of neuronal cells was significantly increased by the addition of $100\;{\mu}g/ml$ of the buthanol or aqueous fraction. At this concentration, the significant increase of the syntheses of protein and RNA, but not of DNA, indicates that the fractions may act on the neuronal cells which are known to be non-dividing cells.

Pulmonary edema is a disease involving the principal symptoms: dyspnea, bloody phlegm, asthma, cough, etc. According to oriental medical references, Jeomglyukdaejosapaetang (J.D.T) was efficacious for dropsy, cough, dysnea, etc, so it was thought to be used for remedy of pulmonary edema. Therefore experimental study was performed to investigate the effects of J.C.T on pulmonary edema of the rats induced by the herbicide, paraquat.Thus the survival rats, respiratory rats, lung weights and histopathological view of the lungs of rats were studied. The results are as follows. 1. The survival rates at 72hours of the rats injected with paraquat and treated with J.D.T increased in B group(J.D.T + Cortex Lycii Radicis + Cortex mori). The others were not different with the control. 2. The respiratory rates of the rats which survived 72hours later significantly decreased in B group(J.D.T + Cortex Lycii Radicis + Cortex mori). 3. The lung weights of the rats which survived for 72hours later significantly decreased in B group(J.B.T + Cortex Lycii Radicis + Cortex mori). 4. The histopathological views of the lungs of rats induced by paraquat were seen severe hemorrhage, edema and some broken alveoli in control group. But B group(J.D.T + Cortex Lycii Radicis + Cortex mori) were seen little hemorrhage and interstitial hyperplasia. According to the above results, J.D.T + Cortex Lycii Radicis + Cortex mort is effective on the remedy for pulmonary edema of rats induced by paraquat.

In order to investigate the effect of Lycii Radicis Cortex on hyperlipidemia, experimental studies were performed on hyperlipidemia rats. Hyperlipidemia model (controll group) was induced by 1% cholesterol fed-diet for 8 weeks. Sample I group fed with 1% cholesterol and 4% Lycii Radicis Cortex diet for 8 weeks. Sample II group fed with 1% cholesterol and 8% Lycii Radicis Cortex diet for 8 weeks. The contents of serum total cholesterol, triglyceride, free fatty acid, phospholipid, HDL-cholesterol and LDL-cholesterol were measured, and fat accumulation in liver and the change of elastic and collagenous fiber in aortic wall were observed. The results were summurized as follows ; 1. The content of total cholesterol in the serum compared with control group tended to be decreased in sample group, but did not show a significance. 2. The content of triglyceride in the serum compared with control group tended to be decreased in sample group, and then sample II group showed a significant value. 3. The content of free fat acid in the serum compared with control group tended to be decreased in sample group, and then sample II group showed a significant value. 4. The content of phospholipid in the serum compared with control group tended to be decreased in sample group, but did not show a significance. 5. The content of HDL-cholesterol in the serum compared with control group tended to be increased in sample group, and then sample I group showed a significant value. 6. The content of LDL-cholesterol in the serum compared with control group tended to be decreased in sample group, and then sample I group showed a significant value. 7.

Lycii fructus has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. In this study, we investigated whether fermentation of Lycii fructus extract (LE) increases the enzymatic activity of the alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). The fermentation of LE by Bacillus subtilis subsp. subtilis and Saccharomyces cerevisiae IFO 2376 was shown to increase the enzymatic activity of ADH and ALDH. TLC analysis of LE and fermented LE (FLE) showed that ADH and ALDH activities increased in different spots. Fraction No. 66 of LE and fraction No. 68 of FLE by Silica gel chromatography showed increased ADH activity of 129.1% and 148.9%, respectively. Fractions No. 128 of LE and FLE by Silica gel chromatography showed increased ALDH activity of 134.1% and 148.1%, respectively. The fraction No. 68 of FLE obtained by HPLC showed new peaks at $R_t$ 11.938min, $R_t$ 22.072min and $R_t$ 28.842min, indicating that ADH activity was increased. The LE and FLE fractions with the greatest increases in ADH activity peaked at the same time ($R_t$ 13min),whereas the LE and FLE fractions with the greatest increases in ALDH activity peaked at different times ($R_t$ 16.307min and $R_t$ 36.640min, respectively).

A simple new method was developed for the determination of betaine in Fructus Lycii using hydrophilic interaction liquid chromatography with evaporative light scattering detection (HILIC-ELSD). Good chromatographic separation and reasonable betaine retention was achieved on a Kinetex HILIC column ($2.1{\times}100mm$, $2.6{\mu}m$) packed with fused-core particle. The mobile phase consisted of (A) acetonitrile and (B) 10 mM ammonium formate (pH 3.0)/acetonitrile (90/10, v/v). It was used with gradient elution at a flow rate of 0.7 mL/min. The column temperature was set at $27.5^{\circ}C$ and the injection volume was $10{\mu}L$. The ELSD drift tube temperature was $50^{\circ}C$ and the nebulizing gas (nitrogen) pressure was 3.0 bar. Stachydrine, a zwitterionic compound, was used as an internal standard. Calibration curve over $10-250{\mu}g/mL$ showed good linearity ($R^2$ > 0.9992) and betaine in the 70% methanol extract of Fructus Lycii was well separated from other peaks. Intraand inter-day precision ranged from 1.1 to 3.0% and from 2.4 to 5.3%, respectively, while intra- and inter-day accuracy ranged from 100.0 to 107.0% and from 94.3 to 103.9%, respectively. The limit of quantification (LOQ) was $10{\mu}g/mL$ and the recoveries were in the range of 98.2-102.7%. The developed HILIC-ELSD method was successfully applied to quantitatively determine the amount of betaine in fourteen Fructus Lycii samples from different locations, demonstrating that this method is simple, rapid, and suitable for the quality control of Fructus Lycii.

예부터 약용 또는 식용으로 쓰였으며, 사람의 체질을 강하게 하고, 혈관연화, 콜레스테롤 저하작용 등에 효과가 있는 것으로 알려져 있는 구기자를 추출, 분획하여 4종의 암세포 주(HepG2, HeLa, MCF-7, C6)를 이용하여 암세포 증식억제 실험을 한 결과, 4종의 암세포주 모두에게 구기자의 ethyl-ether층(LFMEE)이 아주 높은 암세포 증식억제 효과가 나타났으며, 특히 유방암세포주인 MCF-7에서도 hexane층 (LFMH)에서 아주 높은 암세포 증식억제 효과가 나타났다. 한편, 인체 간암세포인 HePG2를 이용하여 quinone reductase 효소 유도 활성 여부를 측정한 결과 분획물 첨가농도 100 $\mu\textrm{g}$/mL에서 1.85배의 높은 효과가 나타났다. 구기자에 미치는 비타민 C의 암세포 성장억제 상승효과를 실험한 결과, 구기자와 비타민 C를 각각 혼합 처리시 낮은 농도에서도 아주 높은 암세포 증식억제 효과가 나타났다. 즉, HeLa와 MCF-7 암세포주에서도 정도의 차이는 있었으나, 구기자 성분과 비타민 C의 조합에 의해 암세포 증식이 억제 또는 사멸되는 나타났으며 본 연구에서 사용한 2종류의 암세포주 모두 구기자와 비타민 C 혼합물의 투여로 인해 증식억제가 현저히 상승됨을 보여주었다. 본 실험을 통해, 구기자의 hexane층(LFMH)과 ethylether층(LFMEE)에서 높은 암세포 증식억제 효과와 암예방 효과가 있는 것으로 추정되며, 비타민 C와 함께 첨가했을 때 낮은 농도의 첨가 시료에서도 높은 암세포 증식억제 상승효과가 나타났음을 알 수 있었다. 구기자의 항암 효과를 상승시키기 위해서는 비타민 C 일정량을 함께 첨가하는 것이 효과적임을 본 실험 결과를 통해 알 수 있었다.
