The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. Recently the biological and pharmacological actions of herb have been studied well such as antibacterial, antidiabetic and antitumor activities. This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillaris extracts against Hepa-1c1c7 and Sarcoma 180 cancer cells in in vivo experimental tests. In in vivo experimental tests using 210 ICR mice, based on flow cytometry, CD3+, CD4+, CD8+ and TNF-${\alpha}+$ splenocytes were significantly (p<0.05) reduced in the Hepa-1c1c7 and Sarcoma 180 inoculated vehicle controls, HP and SP, compared to those of the intact vehicle control on both the $28^{th}$ day and the $42^{nd}$ day, respectively. These decreases of CD3+, CD4+, CD8+ and TNF-${\alpha}+$ cells induced by tumor inoculations were significantly (p<0.05) inhibited by mACH treatment regardless of the type of experiments and tumor cells inoculated. The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

우리 나라에서 인체감염을 일으키는 스파르가눔의 중간숙주를 파악하고, 각 단계의 유충을 관찰하기 위하여 이 연구를 수행하였다. 실험실에서 키운 물벼룩(Mesocyclops leuckarti, Eucyclops serrulatusi Moina sp.)과 참개 구리의 올챙이를 각 단계의 유충에 접촉 감염시키고, 다음 단계의 유충을 얻어 다른 숙주에 감염시켰다 각 시기에 있는 유충의 발육과 형태를 관찰한 바 다음의 결과를 얻었다. 1. 실험적으로 스파르가눔을 개와 고양이에 감염시켜 얻은 Spirometra의 충란을 증류수에서 $29^{\circ}C$로 배양한 결과 10~14일에 유충(coracidium)이 탈각 부화하였다. 이 때 광선이 탈각을 촉진하였다. Coracidium은 평균 $43.8{\times}36.9{\;}{\mu\textrm{m}}$의 크기이었고, 길이 $12.8{\;}{\mu\textrm{m}}$의 섬모로 덮혀 있었다. 2. Coracidium에 노출된 물벼룩 중에서 M. leuckarti와 E. serrulatus가 procercoid 유충을 체강에 가지고 있었 다. 감염 5일에 형태가 갖추어지고, 10일에 제 2중간숙주에 감염 력을 가지며, 한 달 이후에는 석회화되었다. 이 유충의 전단에는 미세한 소극이 밀생하여 있었고, 체내에 칼슘소구(calcium corpuscles)가 관찰되고, 후단에 cercomer가 형성되어 있었다. 3. 감염된 물벼륵과 접촉시킨 모든 올챙이의 복강에서 스파르가눔(plerocercoid 유충)이 회수되었다. 을챙이에 서 감염 후 20일에 길이 1mm이내의 서양배 형의 작은 충체가 관찰되었고, 45일에는 길이가 약 4mm정도의 유충이 회수되었다. 4. 마우스에 경구감염시킨 procercoid 유충은 감염 후 17일 및 19일에 스파르가눔으로 성장하였고 각각 5.7% 및 7.1%의 충체가 회수되었다. 5. 올챙이에서 얻은 스파르가눔을 개와 고양이에 감염시킨 결과 15~17일에 대변에서 Spirometra의 충란이 검출되 었다. 감염 후 6주에 개에서 회수한 충체는 길이가 110cm, 폭이 0.8cm이 었다. 성숙 편절의 자궁이 4~5회 의 나선형이고 한 펀절의 길이와 폭의 비율이 1 : 2.9이었다. 횡단 절편된 펀절에서 생식공과 질구가 간격을 두 고 개구하고, 음경낭과 저정낭이 하나의 낭을 형성하여 Spirometra erinacei의 기술과 일치하였다. 이 연구의 결과로 우리 나라의 논, 저수지, 수로, 개천 등에 흔히 분포하는 담수 갑각류 중에서 M. leuckarti 와 E. serrulatus가 스파르가눔의 중간숙주가 될 수 있음을 확인하였다. 충란의 배양에서부터 종숙주의 충란 배출까지 약 2개월 정도의 기간이 소요되었고, 우리 나라 자연환경에서는 5일에서 7월에 주로 이 충체의 유충이 발육되고 전파되는 것으로 추측되었다.

Carnosine is a dipeptide $(\beta-alanyl-L-histidine)$ found in mammalian brain, eye, olfactory bulb and skeletal muscle at high concentrations. Its biological functions include antioxidant and anti-glycation activities. The objectives of this study were to investigate anti-diabetic effects of carnosine as determined by blood glucose levels, glucose tolerance test (GTT), glycosylated hemoglobin, and serum biochemical and lipid levels in streptozotocin-induced diabetic mice. There were five experimental groups including normal (ICR mice), control (saline), and three groups of carnosine at doses of 6, 30, and 150 mg/kg b.w.. Carnosine was orally administered to the diabetic mice everyday for 12 weeks. There was no significant difference in body weight changes in carnosine-treated groups compared to the control. The treatments of carnosine at the dose of 6 mg/kg significantly decreased the blood glucose level compared with the control at 2 and 4 weeks. The treatments of carnosine at the doses of 6 and 30 mg/kg significantly decreased the blood glucose levels in GTT and glycosylated hemoglobin compared with the control. Carnosine significantly increased total proteins compared with the control. Carnosine at the dose of 6 mg/kg significantly decreased total cholesterol and triglyceride in the serum compared to the control. These results suggest that carnosine at a low level has a hypoglycermic effect resulting from reduction of blood glucose and that a carnosine-containing diet or drug may give a benefit for controlling diabetes mellitus in humans.

The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp. and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. This experiment was conducted to investigate the effects of Artemisia capillaris extracts on the amounts of splenocytes-derived cytokine ($TNF-{\alpha},\;IL-1{\beta}$ and IL-10). In in vivo experimental tests using 210 ICR mice with Hepa-1c1c7 or sarcoma 180 cancer line, splenocytes derived cytokine contents were significantly (p < 0.05) reduced in the Hepa-1c1c7 and Sarcoma 180 inoculated vehicle controls, HP and SP, compared to those of the intact vehicle control on both the $28^{th}$ day and the $42^{nd}$ day, respectively. However, these decreases of $TNF-{\alpha},\;IL-1{\beta}$ and IL-10 levels induced by tumor inoculations were significantly (p < 0.01, p < 0.05) inhibited by mACH (Artemisia capillaris methanol extracts) treatment regardless of the type of experiments and tumor cells inoculated. The results suggest that Artemisia capillaris methanol extracts have prominent anti-inflammation effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

The object of this study was to obtain acute information (single oral dose toxicity) of Taraxaci Herba (Dried total parts of Taraxacum platycarpum. H.Dahlstedt (Compositae)), has been traditionally used in Korean medicine for treating various inflammatory diseases. In order to observe the 50% lethal dose (LD 50), approximate lethal dosage (ALD) and target organs, test articles were once orally administered to female and male ICR mice at dose levels of 2,000, 1,000, 500 mg/kg according to the recommendation of Korea Food and Drug Administration Guidelines. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after single oral treatment of Taraxaci Herba aqueous extracts according to KFDA Guidelines with organ weights and histopathological observations of 12 types of principle organs. After single oral treatment of Taraxaci Herba aqueous extracts, we could not find any mortality and toxicological evidences up to 2,000 mg/kg treated group, the limited dosages in rodents at body and organ weights, clinical signs, gross and histopathological observations. Except for slight soft feces, which were detected in male mice treated with 2,000 mg/kg of Taraxaci Herba aqueous extracts at 1 day after end of treatment. The results obtained in this study suggest that the LD 50 and ALD of Taraxaci Herba aqueous extracts in both female and male mice after single oral treatment were considered as over 2,000 mg/kg because no mortalities were detected up to 2000 mg/kg that was the highest dose recommended by KFDA and OECD. However, it also observed that the possibility of digestive disorders, like diarrhea when administered over 2,000 mg/kg of Taraxaci Herba aqueous extracts in the present study, but these possibilities of digestive disorders can be disregard in clinical use because they ate transient in the highest dosages male only.

To study the age-related morphological differences of the retinal pigment cells and Bruch's membrane of mouse, retinae of one week-old, five weeks-old, eight weeks-old, six months-old, twelve months-old, eighteen months-old, twenty-four months-old and thirty months-old ICR mice were dissected out under anesthesia. Pieces of the tissue taken from the posterior region of the retina were fixed in 2.5% glutaraldehyde-1.5% paraformaldehyde (0.1 M Millonig's phosphate buffer, pH 7.3), and 1% osmium tetroxide (0.1 M Millonig's phosphate buffer, pH 7.3), and embedded in araldite mixture. The ultrathin sections were stained with uranyl acetate and lead citrate, and were observed under a JEM 100 CX-II electron microscope. Observed results were as follows: 1. Retinae of one week old mouse exhibit that some parts of the pigment cell provided with basal foldings, whereas other parts of the one contain without basal foldings. After (ive weeks-old, all retinal pigment cells have the basal infoldings. 2. In the one week-old, stage 1 and stage 2 melanosomes were observed in the retinal pigments cells, but after five weeks-old, most of the retinal pigment cells contain some matured stage melanosomes (stage III and stage IV). 3. The phagosomes in the retinal pigment cells were increased during aging. 4. After eighteen months-old, electron dense materials are observed within the basal infoldings. 5. After eighteen months-old, the thickness of the Bruch's membrane is prominently increased. The thickness of the basal laminae of the pigment cell and the choriocapillary endothelium is more prominently increased as compared with that of the other components of the Bruch's membrane. 6. The thickness of the basal lamina of the pigment cell is more prominently increased as compared with that of the choriocapillary endothelium on aging. From the above results, it was suggested that the pigment cell and Bruch's membrane matures structurally In five weeks, and the function of the pigment cell is prominently suppressed around eighteen months-old, and thereafter the functional suppression is continued on aging.

Morphological difference of the renal glomerulus at different age groups have been studies in one week-old, five weeks-old, eight weeks-old, six months-old, twelve months-old, eighteen months-old, twenty-four months-old, and thirty months-old ICR mice. Pieces of the tissue taken from the renal corticies were fixed in 2.5% glutaraldehyde-1.5% paraformaldehyde solution (0.1 Millonig's phosphate buffer pH 7.3), and 1% osmium tetroxide solution (0.1 M Millonig's phosphate buffer, pH 7.3), and were embedded in araldite mixture. The ultrathin sections were stained with uranyl acetate and lead citrate solution, and were observed under a JEM 100CX-II electron microscope. The results were as follows: 1 In the one week-old mouse, thicknesses of the three layers of the glomeluar basal lamina (lamina densa, lamina rara interna and lamina rara externa) are similar, but in the five weeks-old mouse, thick lamina densa becomes a greater portion of the thickness of whole glomerular basal lamina. 2. No difference was noticed between thickness of the renal glomerular basal lamina of the five weeks-old mouse compare with that of the one week-old one, but basal lamina of the eight weeks-old one is thickened considerably and thicknesses were maintained through twelve months-old one. After eighteen months, the thickness of the glomerular basal lamina is increased remarkably. 3. After eighteen months, electron dense deposits within the basal lamina of the renal glomeruli are observed frequently. 4. Amount of the microfilaments in the mesangial cells and the mesangial matrices are increasing during aging. 5. The thicknesses of the basal laminae of the Bowman's capsule are increasing during aging. 6. After twenty four months, the proximal tubular cell-like parietal cells with well developed microvilli are observed frequently. From the above results, it was suggested that the renal glomerulus matures structurally in five weeks, and the function of the glomerulus is suppressed after eighteen months.
