The objective of this study was to evaluate the effects of dietary Solanum nigrum L. (SNL) and Glycyrrhiza uralensis Fisch (GUF) mixture powder on performance and blood compositions of broilers. Seven-day old Ross broiler male chickens were randomly given into one of the 5 dietary treatments for 5 weeks: 1) no SNL-GUF and antibiotics (control); 2) 5 ppm avilamycin (T1); 3) 0.5% SNL and GUF (T2); 4) 1.0% SNL and GUF (T3); and 5) 2.0% SNL and GUF (T4). Each dietary group (n = 10) had three replicates. Body weight gain, feed intake and feed conversion ratio of broiler chickens were not significantly different among treatments. Carcass weight was highest at both 4 (P<0.05) and 6 weeks (P>0.05) in the treatment with 1.0% SNL and GUF. Liver, but not Spleen, weights at both 4 and 6 weeks were significantly higher in the treatments with 0.5% SNL and GUF treatment (P<0.05). The contents of protein, albumin, bilirubin, glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), glucose, triglyceride (TG) and cholesterol in blood serum at the 4weeks and 6 weeks were not significantly influenced. These results suggest that addition of SNL and GUF could be use a substitutes for antibiotics since they did not influence to the productivity and the blood composition of the broilers.

The whole herbs of solanum nigrum L were extracted in boiling water (SNL-W), and the extracts were separated with butyl alcohol fraction (SNL-W/B) and aqueous fraction (SNL-W/W) by the solvent extraction method. The total alkaloid and total saponin content mensuration were used to identify the alkaloid composition of methanol fraction extracted from the aqueous fraction. The venom of honey bee was used to induce the rat peritoneal mast cell to secreting the histamine. The results show that the water soluble alkaloid composition of solanum nigrum L (SNL-W/W/M) has a significant inhibitory effect on the histamine release.

To identify and isolate anticancer active compounds from Solanum nigrum, S. nigrum was extracted with MeOH and then fractionated with various organic solvents ($CH_2Cl_2$, EtOAc, n-BuOH, and $H_2O$). The cytotoxic effects of the MeOH extracts from S. nigrum and its organic solvent-soluble fractions were also tested in HT29 cells. All the MeOH extracts of S. nigrum and its organic-solvent extracts induced cytotoxicity in the HT29 cells. Among the extracts, $H_2O$ was the most effective. The $H_2O$ extract was purified further by repeated silica gel, Sephadex LH-20, Diaion HP- 20, and RP-18 column chromatography. An active anticancer compound, Des-N-26-methylene-dihydrotomatidine, was isolated with a molecular weight of 416 and a molecular formula of $C_{28}H_{48}O_2$. Analysis of the cytotoxic effects of Des-N-26-methylene-dihydrotomatidine on the HT29 cells compared to those of tomatine and tomatidine are similar in its structure, is higher than tomatidine above the 40 ${\mu}g/ml$ concentration, but lower than tomatine. This is the first study to describe the anticancer activity of Des-N-26-methylene-dihydrotomatidin, isolated from S. nigrum. Des-N-26- methylene-dihydrotomatidine seems to have potential as a natural bioactive compound.

For the purpose of developing new anti-HIV agents from natural sources, the extracts of Solanum nigrum L. were tested for their inhibitory effects on HIV-1 replication and its essential enzymes as the reverse transcriptase (RT), protease and ${\alpha}$-glucosidase. In the assay of HIV-1-infected human T-cell line, water extracts inhibited the HIV- 1 -induced cytopathic effects with IC (inhibitory concentration) of 100 ug/ml. Moreover water extracts (100ug/ml) of aerial parts showed strong activity of 32.6% on anti-HIV-1 PR using the activity of the enzyme to cleave an oligopeptide. In the HIV-1 reverse transcriptase inhibition assay, aqueous extract a inhibited 17.4%, but no glucosidase inhibitory activities. We found out this result, for these samples it is possible that the inhibition of the viral replication in vitro is due to the inhibition at least one of PR and RT. It would be of great interest to identify the compounds which are responsible for this inhibition, since all therapeutically useful agent up to date are PR, RT and ${\alpha}$-glucosidase inhibitors.

Objectives In human myeloid leukemia cells, there are no specific features of apoptosis compared with apoptosis in other cell types. Solanum nigrum L.(SNL) is a deciduous tree, which is widely distributed in Korea with reported anti-tumor, anti-inflammatory and non-specific immune-enhancing properties. Although the plant has been clinically used for treating a variety of diseases, its bioactive ingredients are unknown and its mode of action potential has never been investigated. Thus anti-tumor property of methanol extract was investigated. Methods In this study, anti-tumor property of methanol extract was investigated by determining its in vitro growth-inhibitory effects on human myeloid leukemia cells. XTT proliferation assay, DNA fragmentation, immunoblot analysis, densitometric analysis were used. Results 1. The methanol fraction of the extracts of SNL induced mitochondria-mediated apoptosis in human myeloid leukemia cells. 2. The methanol fraction exhibited relatively higher cytotoxic activity in a dose-dependent manner than chloroform, and hexane fraction. 3. Typical ladder profile of Oligonucleosomal fragments were appeared. 4. The secreted cytosolic cytochrome C level was increased by treatment of methanol fraction. Conclusions Methanol fraction of SNL is capable of inducing apoptosis in human myeloid leukemia cells.

The objective of the study was to observe the anti-diabetic effect of Solani nigri Herba(SH). The following experimental results were derived from the measurement of the levels of glucose, GOT and GPT in the serum and weight from a group of experimental rats by way of the injection of streptozotocin as well as the oral administration of Solani nigri Herba water extracts. The glucose level in the serum significantly decreased in the Solani nigri Herba-dosed group(SH2,12.6 mg/100 g rat weight) on the 10th day. The GOT level of SHI(4.2 mg/100 g Solani nigri Herba) and SH2 in the serum slightly decreased, but no significance to compare with control group. The GPT level of SH1 and SH2 in the serum slightly decreased, but no significance to compare with control group. The weight of rat of SH1 and SH2 in the serum slightly increased, but no significance to compare with control group. In conclusion, Solani nigri Herba appeared to have significance inhibitory effects on the rise of blood sugar level in the experimentally induced diabetics.

The results of immune response and antiallergic reaction were as follows. 1. Hemagglutinin titer and hemolysin titer were increased in case of AMR, AR, SNH. But the results were not recognized as having significance. 2. PFC was increased in case of AMR, AR. But the results were not recognized as having significance. 3. RFC was increased in all groups, and the results in the AR, SNH were significant. 4. In experimentation of phagocytic activity in peritoneal exudate cells, AR and SNH showed significant increase. In spleen cells AR and SNH showed significant increase. In monolymphocytus cells AMR, AR and SNH were increased, but result of AMR was of no significance. 5. I examined promotion on spleen cells transformation. As these results, AMR showed increase in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ in comparison with control group. And in $500{\mu}g/m{\ell}$ AMR showed increase in case of 24 hours, 72 hours incubation, but showed decrease in case of 48 hours incubation. AR showed increase in all. In $50{\mu}g/m{\ell}$ SNH showed increase in comparison with control group. And in $500{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ SNH showed increase in case of 24 hours, 48 hours incubation, but showed decrease in case of 72 hours incubation. 6. I examined proliferation of spleen cells. As these results AMR and SNH showed the highest increase in $50{\mu}g/m{\ell}$, but showed the lowest increase in $5000{\mu}g/m{\ell}$. AR showed the highest increase in $500{\mu}g/m{\ell}$, but this result was the almost same in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$. And AMR, AR, SNH showed higher activity in Lipopolysaccharide than Concanavalin A. 7. In all groups results of PCA were decreased in 2 week. In 4 week AR and SNH showed decrease, but AMR didn't show change. In 6 week AR and SNH showed decrease, but on the contrary AMR showed increase. 8. In experimentation on histamine contents, AMR showed significant increase at first agent contact. And AR, SNH showed decrease at first agent contact, but these results were of no importance. At second agent contact AMR showed decrease, but was of no importance. AR, SNH showed significant decrease. At third agent contact, AMR showed significant increase. AR, SNH showed decrease, but these results were of no importance. From above these results, AR and SNH showed good effects on immunoreaction. And all the herb medicines in this examination showed good effects in promotion on spleen cells transformation and proliferation of spleen cells, especially activated B-cells. AR, SNH showed good effects on anti-allergic reaction, but AMR was almost inefficient. Accordingly I think that AR shall be used in disease bringing about a lowering of immunity, that is, AR shall be used in strengthening the body resistance. And I think that SNH shall be used in eliminating pathogenic factors with strengthening the body resistance. It is necessary to a deep study in future.

백혈병은 조혈계통의 악성 증식성 질환으로서 현재까지 주로 화학약물요법에 의존하고 있는 실정이다. 화학약물요법은 백혈병 세포를 소멸시킬 수 있지만 또한 인체에 여러 가지 독성 반응 및 부작용을 일으키기도 한다. 따라서 중서의결합으로 백혈병 치료에 접근하는 것은 중요한 의미를 갖는다. 중의학에서 소아 백혈병을 치료하는 경우 청열해독법(淸熱解毒法), 부정보허법(扶正補虛法), 활혈화어법(活血化瘀法)을 주로 사용한다. 청열해독법은 백혈병의 조기치료에 주로 활용되는데, 인체의 저항력을 증강시켜 화학약물요법을 실시하는 동안 흔히 나타날 수 있는 감염증상을 예방하는 효과를 얻을 수 있다. 부정보허법(扶正補虛法)은 주로 화학약물요법의 유도 완화기 및 치료효과의 유지를 위하여 활용되는데, 이는 인체의 면역력을 향상시켜 화학약물요법이 인체에 미치는 손상을 경감시킬 수 있다. 활혈화어법(活血化瘀法)은 미세순환을 개선시키는 작용을 하며 골수의 조혈기능을 촉진하고 면역기능을 조절하며 또한 일부 활혈화어제(活血化瘀劑)는 백혈병 세포에 직접적인 억제효과를 보인다. 소아백혈병에 대하여 화학약물요법을 진행하는 동안 중약을 같이 병행하는 경우 다음과 같은 과정으로 나누어 실시할 수 있다. 1. 유도완화치료(화학요법)단계: 이와 같은 치료과정은 대개 화학약물요법으로 인한 극심한 독성반응이나 주작용을 나타내게 되는데, 이 과정에서 중약치료를 병행하면 신속하게 증상을 개선시킬 수 있다. 만약 구토나 설사와 같은 소화계 부작용이 나타나면 화위강역법(和胃降逆法)을 활용하고, 감염 증상이 나타나면 부정(扶正)과 거사법(祛邪法)을 병행할 수 있다. 화학약물요법을 진행한 후 신체가 극도로 허약해지고 골수의 기능이 심하게 억제되는 경우는 주로 부정(扶正)시키는 중약을 사용하면서 익기양혈제(益氣養血劑)를 곁들이고 보조적으로 단삼(丹蔘), 당귀(當歸), 천궁(川芎), 계혈등(鷄血藤) 등과 같은 활혈화어제(活血化瘀劑)를 사용하여 골수의 조혈기능을 회복시킨다. 2. 치료효과의 유지단계: 본 과정에서는 중약치료에 있어서 부정(扶正)과 거사법(祛邪法)을 병행한다. 화학약물요법을 실시하는 동시에 거사제(祛邪劑)를 중용(重用)함으로써 화학약물요법의 효과를 강화시킨다. 화학약물요법이 끝난 뒤 부정(扶正)시키는 약물을 중용(重用)하여 인체의 면역기능을 증강시키고 백혈병세포를 억제시킨다. 3. 치료효과의 유지 및 강화단계: 치료효과의 유지단계에서는 변증논치(辨證論治)의 원칙에 입각하여 항암효과가 있는 중약을 활용할 수 있는데, 예를 들어 백화사설초(白花蛇舌草), 산자고(山慈?), 청대(靑黛), 용규(龍葵) 등을 사용할 수 있고, 육신환(六神丸)을 장기적으로 복용하여도 된다. 소아백혈병 치료에 있어서 중서의결합의 치료법을 활용하는 경우 다음과 같은 내용에 주안점을 둘 수 있다. 화학약물요법을 진행하는 과정에서 중약을 병행하여 투여하는 경우 사진합삼(四診合參)을 근간으로 종합적인 분석을 통하여 병인(病因)을 살피어 치료에 임하도록 한다. 약물의 선택과 처방의 구성은 반드시 변증논치(辨證論治)의 원칙하에 이루어져야 한다. 화학약물요법과 중약치료를 병행하는 과정에서 변증(辨證)과 변병(辨病)이 서로 결합되고 부정(扶正)과 거사법(祛邪法)을 병행하여 활용한다. 정체관(整體觀)에서 출발하여 환자를 관찰하는 동시에 특징적인 증후(證候)에 대한 변증논치(辨證論治)도 중요하며, 또한 백혈병 환자의 유형(類型)이나 임상 혈액검사 소견, 골수의 양상, 화학요법의 진행단계 및 환자의 연령과 체질 등을 충분히 가만하여 종합적인 분석을 토대로 치료법을 선택하여야 중약요법과 화학약물요법의 협동적인 효과를 증폭시키고 백혈병치료에 새로운 전기를 마련할 수 있을 것이다.
