누에고치를 2 N HCl 용액으로 110℃, 48시간 가수분해한 후 중화하여 냉동건조하여 얻은 누에고치 산가수분해물의 아미노산 조성은 glycin이 43.25%, alanine이 34.39%, serine 10.05%, valine이 2.44%였고 필수 아미노산은 7.12% 차지하였다. 누에고치 산가수분해물의 사료이용효율은 카제인과 같았다. 1~5% 실크분말의 첨가에 의한 간의 무게, 간효소활성(GOT, GPT), 혈청알부민, 혈청 총단백질의 함량은 영향이 없어 단백질의 질이 낮은 것으로 평가되었다. 흰쥐에 고콜레스테롤, 고지질, 고설탕사료를 각각 섭취시키면서 5% 누에고치 산가수분해물을 첨가하였을 때 혈장 지질농도에 미치는 영향은 중성지질의 감소, 인지질과 HDL의 증가 등 혈액지질조성에 바람직한 결과를 보였으나, LDL과 총콜레스테롤을 높히는 좋지 못한 효과도 나타냈다. 그러므로 누에고치 산가수분해물은 단백질 급원 식품으로보다는 이를 이용한 펩타이드의 생리기능 또는 식용 이외의 화장품재료, 의약용재료, 포장제 등과 기타 물리 화학적 특성을 기초로 한 다양한 범위의 응용이 더욱 적합하다고 생각되며, 혈액지질 개선효과에 대해서는 심층적인 연구가 필요하다. Acid hydrolysates of cocoon was gained by acid hydrolysis of 2 N HCl, 110℃, 48 hours, neutralization and desalting from the cocoon. The amino acid compositions of acid hydrolysates of cocoon were glycine 43.25%, alanine 34.39%, serine 10.05% and valine 2.44%. The contents of essential amino acid was 10.05%. Food efficiency ratio of acid hydrolysates of cocoon group was equal to the reference protein, casein. Liver weight, GOT, GPT activity, serum albumin and serum total protein level of rats were not significantly different among the experimental groups. Therefore, the protein acid hydrolysates of cocoon is not of high quality. When the rat fed with high cholesterol, high lipid, and high sucrose diet was administered with 5% acid hydrolysates of cocoon, its plasma lipids concentration of acid hydrolysates of cocoon was favorably affected: its triglyceride was decreased, and the level of phospholipid and HDL cholesterol were increased. There was also an unfavorable effect: the levels of LDL cholesterol and total cholesterol went up. Therefore, the acid hydrolysates of cocoon is not a good protein food source, but it can be used as cosmetic, medical, or packing material. Further research will reveal how it will affect or improve plasma lipid.

本 實驗은 성기능 억제제에 의해서 低下되는 男性의 性機能(혹은 生殖機能)을 枸杞雙和湯을 利用하여 保護할 수 있는 實驗을 수행하였다. 男性의 性機能을 低下시키는 物質로는 環境汚染物인 2,3,7,8-Tetrachlorodibenzo-p-dioxin(TCDD)과 항생제의 일종인 Ketoconazole를 사용하였다. TCDD는 대부분의 식물체에 존재하는 flavonoid 물질과 마찬가지로 호르몬 교란물질의 일종으로써 estrogen receptor에 결합하며 cytochrome P450 side chain cleavage enzyme (P-450scc)에 의해서 prognenolone으로 轉換되는 過程을 막아서 testosterone의 合成, 혈액내 testosterone의 濃度, 睾丸 및 副睾丸의 發育 그리고 정자의 形成 등을 抑制한다. Ketoconazole은 항진균 물질로 사람과 동물에서 testosterone의 合成을 沮害한다. 枸杞雙和湯 煎湯液은 mount frequency, intromission frequency를 대조군에 비하여 유의하게 증가시켰으며, TCDD와 枸杞雙和湯 煎湯液을 함께 투여한 군에서 TCDD만을 투여한 군보다 mount frequency는 유의하게 증가시켰으며, ketoconazole과 TCDD에 의하여 저하된 혈청 testosterone 농도를 유의하게 증가시켰다. To evaluate effect of Gugissanghwatang water extract on the male sexual behavior and serum testosterone concentrations, experiments performed in male rats. The results were obtained as follows: 1. Mount frequency and intromission frequency were increased significantly after the administration of Gugissanghwatang water extract in normal rats. 2. Intromission frequency were increased significantly after the administration of Gugissanghwatang water extract in TCDD-treated rats. 3. Serum testosterone concentration were increased significantly after the administration of Gugissanghwatang water extract in ketoconazole-treated rats. 4. Serum testosterone concentration were increased significantly after the administration of Gugissanghwatang water extract in TCDD-treated rats.

Rat의 1 차간세포 배양에 environmental 발암물질을 첨가하여 간의 DNA에 손상을 준뒤 복구되는 정도를 정량적으로 측정하였다. 즉, CaCl density gradient 을 초원심분리(ultra-centnfuge)로 만들어 DNA를 추출해서 그것에 결합된 [^3H]-thymidine양을 liquid scintillating 측정기로 측정하였다. Direct 발암물질인 MNNG에 의한 손상의 복구는 short patch 형태로 복구가 빨리 일어나고, indirect 발암물질인 Benzo(a) Pyrene에 손상의 복구는 large patch 형태로 복구가 천천히 일어난다. [^3H]-thymidine과 발암물질을 세포에 같이 넣고 UDS을 유도시키는 실험에서 B(a)P에 대한 손상의 복구는 12시간까지 계속해서 증가되었으나, MNNG에 대한 손상의 복구는 3시간안에 급속히 증가된 후 그 수준을 12시간 까지 유지시켰다. 발암물질을 세포에 넣어 2시간 동안 손상을 준후 [^3H]-thymidine을 세포에 첨가하여 UDS을 유도시키는 실험에서 B(a)P에 의한 복구는 실험 시작후 3-6 hr에서 최대를 보였다. 또 MNNG에 대한 실험에서는 0-3 hr에서 최대를 보였다. Indirect 발암물질은 세포내에서 대사가 되어야 DNA에 손상을 입힐수 있어 간세포를 얻은 후 18시간 이내에 실험을 시작해야 그 물질의 DNA와 결합하는 성질을 잘 나타낼수 있었다. Dose-response 실험에서는 MNNG는 10^-4M에서 B(a)p는 10^-5M에서 최대값을 얻었다. The ability of direct and pro-carcinogens to induce unscheduled DNA synthesis(UDS) in primary culture of hepatocytes was examined. Hepatocytes were isolated from adult male rats with collagenase perfusion technique and maintained in short-term monolayer culture on collagen-coated plates in serum free modified Waymouth's medium. Incorporation of [^3H]-thymidine into DNA in the presence of hydroxyurea was used to measure UDS. N-Methyl-N'-nitro-N-nitrosoguanidine(MNNG) which elicit a "short-patch" type of DNA repair and benzo(a) pyrene (B(a)P) which result in a "long-patch" type of DNA repair were used as standard carcinogens to show repair patterns. In continuous labelling experiments, UDS induced by B(a)P was increased linearly for 12hr in cultures, but that of

The Corrlation between Protein Methylation Ⅰ and Ⅲ Reaction and Immune Responses from Mouse Splenic Lymphocytes stimulated by Lipopolysaccharide

LPS로 감각한 비장 임파구의 protein methylase Ⅰ 및 Ⅲ의 비활성은 각각 대조군의 3 및 4배로 증가하였으며, protein methylase Ⅰ은 LPS 처리후 36 시간에서, protein methylase Ⅲ는 72 시간에서 각각 최대의 활성을 보였다. 48 시간 동안의 비장 임파구 배양에서 protein methylase Ⅰ에 의한 arginyl 잔기의 methyl화 반응, protein methylase Ⅲ에 의한 lysyl 잔기의 methyl화 반응, DNA합성, 그리고 polyclonal 항체 형성 반응등이 SF보다 SIBA에 의해 더 저해되었다. SIBA에 의한 억제는 배양기간 중 언제라도 투여한 즉시에 나타났다. 반면 SF의 억제 효과는 배양 초기 12 시간 이내에 첨가해야 만이, 또 투여 후 36 시간이 지나야 저해효과가 보이기 시작했는데 그 후 급격히 증가하여 배양 72 시간 이후부터는 SIBA의 저해 효과보다 더 커져 protein methylase Ⅰ 및 Ⅲ의 in vitor 억제 정도와 일치하였다. 이들의 결과들은 protein methylase Ⅰ 및 Ⅲ가 LPS에 의한 비장 임파구의 면역기능 발현에 밀접하게 관여하고 있음을 시사하고 있다. The induction of protein methylase Ⅰ preceded protein methylase Ⅲ induction in the lipopolysaccharide-induced splenic lymphocyte cultures. The methylation of arginyl and lysyl residues, and the proliferative and polyclonal antibody responses at 48 hr of culture were inhibited more sensitively by SIBA. Regardless of when added, SIBA showed its effects on the responeses immediately after addition. The effects of SF were no longer observed when added later than the first 12 hr in the 48 hr experiment. At 96 hr of exposure, the effects were higher than those of SIBA. The data suggest that the methylation by these enzymes is associated with the immune responses of lymphocytes cultured with lipopolysaccharide.

嚴翼都,金福亮,白汶基 圓光大學校 醫科學硏究所 1986 圓光醫科學 Vol.2 No.2

The enzymatic carboxyl methyl esterification of red blood cell (RBC) membrane protein has been investigated in the isolated membrane and intact rat RBC population of different ages separated by density gradient centrifugation. The activity of cytosolic protein methylase Ⅱ was decreased according to the cell ageing, but isolated membrane protein from RBC of different age showed an age-related increased ability to act as methyl accepting substrates. Membrane proteins were shown to be the natural and excellent substrates for the cytosolic protein methylase Ⅱ compared with protein methylase Ⅰ and Ⅲ in the RBC cell so that the carboxyl methylation of membrane protein was the major methylating reactions in vitro and vivo. When RBC were incubated with media containing L-[methyl-^3H] methionine and 16.7 mM glucose, the [^3H]-methyl incorporation into the carboxyl group of membrane protein was 3.12 pmole/㎎ protein but incubated with media containing L-[methyl -^3H] methionine and 5.6 mM glucose, the amount of carboxyl methylation was 2.36 prnole/㎎ protein. About 1.4 fold increase in membrane protein carboxyl methylation was observed in intact younger RBC in comparison with intact older RBC in above media.
