모체의 당뇨병은 신생아 호흡부전 증후군의 중요한 소인의 하나이며, 이것은 태아의 폐성숙이 지연되어 폐포를 안정화시키는 표면활성물질의 결여에 기인하는 것으로 알려져 있다. 폐의 표면활성물질은 지질과 소량의 단백으로 이루어진 복합물질로서 그 주성분은 phosphatidyl choline이며 동물의 종속에 관계없이 임신 말기에 그 양이 현저히 증가한다. 양수내 인지질은 주로 태아 폐에서 유래하므로 임신 말기의 양수내 lecithin/sphingomyelin(L/S)비 측정으로 태아의 호흡부전 증후군을 예측할 수 있다. 일반적으로 당뇨병 모체의 양수는 L/S비가 낮아 당뇨병 산모로 부터 출생한 신생아에서 호흡부전증의 발생빈도가 높으므로 이를 예방하기 위하여 부신피질호르몬의 투여가 고려되고 있다.

Objectives: This study aimed to evaluate the evidence available in the literature for the safety and efficacy of Dioscoreae Rhizoma (DR) for the treatment of peripheral neuropathy. Methods: Literature searches were performed in MEDLINE and three Korean medical databases up to April 2013. All studies evaluating the effects on peripheral neuropathy or the safety of DR monopreparations were considered. Results: Three studies - DR extract per os (po) on diabetic neuropathy in mice, DR extract injection on the peripheral sciatic nerve after crush injury in rats and DR extract injection to patients with peripheral facial paralysis proved that DR treatments were effective for the treatment of nerve injuries. Conclusions: In conclusion, we found the DR has a strong positive potential for the treatment of peripheral neuropathy, but studies addressing direct factors related to the nerve still remain insufficient.

Several biological activities of extracts from roots of Cichorium intybus Linne (Compositae) were studied in this paper. The antiinflammatory activity of the methanol extract of this root was investigated against carrageenin induced edema in rat‘s hind paw. Significant inhibitory effects were observed at the dose of 1,000 mg/kg and were compared with aspirin as a control. The hepatoprotective activities of the methanol extract, ethylacetate and butanol fraction were studied on mice whose livers are damaged by $CCl_4$. The serum transaminase activities (ALT, AST) were reduced at the dose of 1,000 mg/kg of the methanol extract, 500 mg/kg of ethylacetate and butanol fraction, respectively. The bile juice secretion was also increased significantly from each fraction. The antidiabetic activity was examined on strepto-zotocin-induced diabetic rats with methanol extract. Methanol extract gave a significant reduction of blood glucose levels in 1 week and 3 weeks.

Changes in the distribution of dopamine and its metabolites, activities of monoamine oxidase, and dopamine uptake were studied inhyperglycemic rat striatum. The hyperglycemia was induced by the administration of streptozotocin (STZ, 40 mg/kg, i.p. for 3 days.). The levels of dihydroxyphenylacetic acid (DOPAC) and homovanillic acid were significantly decreased without change in dopamine level in the synatic cleft 14 days after STZ treatment. In the synaptosome, the dopamine level, however, was significanly increased after the treatment. But the DOPAC level in the synaptosome was decreased 14 days after the treatment. The affinity of dopamine uptake was significantly decreased without changes in the velocity 14 days after the treatment. However the response to uptqke inhibitor was unchanged. The striatal monoamine oxidase activities were also decreased in the hyperglycemic state. These results indicate that various parameters of striatal dopamine activities were decreased in the hyperglycemic rats. Furthermore, it suggests that the increase in dopamine level of synaptosome might be due to the decrease in the release of dopaine in hyperglycemic state.

We determined whether the supplementation of Polygonatum Odoratum (Mill) Druce (POD) extract had a good effect on insulin resistance in peripheral tissues of 90% pancreatectomized (Px) and sham-operated (Sham) male Sprague Dawley rats. Px and Sham rats were divided into two groups; one group daily consumed 0.3 g of POD extracts per 1 ㎏ body weight for two months, and the other group had a placebo. All rats freely consumed a 40% fat diet. At the end of the experiment, a euglycemic hyperinsulinemic (EH) clamp was performed in a fasting, awake, and unstressed state to determine insulin resistance. At EH clamp, body weights were higher in Sham rats than Px rats, and serum glucose levels of baseline were affected by diabetic status and POD administration. Serum insulin concentrations were higher in Sham rats than Px rats, and POD administration decreased them in Sham rats compared to P. Glucose disposal rates in peripheral tissues increased with POD in both Px (n=10) and Sham (n=10) rats. But glycogen deposits in soleus muscle increased with POD administration in Px and Sham rats, and total glycogen synthase activity and fraction velocity were higher in POD groups. Triglyceride contents in quadriceps muscles decreased with POD in Px rats. In conclusions, POD improves insulin resistance by enhancing glucose utilization with increasing glycogen deposit and decreasing triglyceride contents in muscles.

Single and repeated-dose toxicity of anti-diabetic herb extract microcapsule (ADHEM) were evaluated according to Toxicity Test Guidelines of Korea Food and Drug Administration using Sprague-Dawley rats. For single-dose toxicity test, kneading ADHEM with sterilized water were administered orally once at dose levels of 0 and 2,000 mg/kg and examined for 14 days. No dead animals, clinical signs and abnormal necropsy findings were observed and also no significant difference in body weights was found. Therefore, the $LD_{50}$ of ADHEM was considered to be higher than 2,000 mg/kg in both male and female rats. For repeated-dose toxicity test, ADHEM were mixed with powder fodder and administerd orally for 28 days at dose levels of 0, 500, 1000 and 2000 mg/kg/day. No dead animals, clinical signs and significant difference in body weights were found. In hematology and serum biochemistry, all values were included within the normal ranges. In relative organ weights, kidney or liver were significantly increased in the 500, 1000 or 2000 mg/kg/day male groups, uterus was significantly increased in the 500 mg/kg/day female group and left adrenal glands were significantly decreased in the 2000 mg/kg/day female group. In histopathological examinations, vacuolation and microgranuloma in the liver, chronic progressive nephropathy and inflammation in the kidney were observed in the 500, 1000 or 2000 mg/kg/day both male and female groups. Therefore, the no observed adverse effect level (NOAEL) of ADHEM was considered to be lower than 500 mg/kg/day in both male and female rats.

The renoprotective effects of Korean Red Ginseng were examined in STZ-induced diabetic spontaneously hypertensive rats (SHR). After 3 day administration of streptozotocin (STZ), animals were divided into four groups : Group 1, hypertensive rats (H); Group 2, hypertensive rats with diabetes (HD); Group 3, hypertensive rats with diabetes administered with 100 mg/kg of ginseng total saponin(GTS); Group 4, hypertensive rats with diabetes administered with 600 mg/kg of ginseng non-saponin (GNS). After 2 weeks oral administraions of GTS and GNS, body weight, kidney weight, plasma glucose, urinary albumin excretion, serum creatinine, urea nitrogen and blood pressure were examined. After 3,7 and 21 day of STZ administration, expressions of TGF-${\beta}$1 and fibronectin in kidney were analyzed by immunoblotting and/or immunohistochemistry. GTS and GNS treatments slightly decreased blood pressure when compared to H and HD groups. Also, GTS and GNS treatments ameliorated kidney hypertrophy without affecting plasma glucose levels. Meanwhile, GNS treatment increased Cu/Zn-SOD activity in kidney and generally showed more efficient renoprotective effects than GTS. We suggest that the renoprotective effects of ginseng partially result from downregulations of TGF-${\beta}$1, fibronectin expressions and anti-oxidative activity of ginseng non-saponin.

Objectives : Collagen decrease of Skin appears through various path ways. One of causes may be the Advanced glycation endproducts (AGEs) that combine formation of glucose and protein. The aim of this study was to explore the prevent wrinkle formation of Paeoniae radix (PR) and heated Paeoniae radix (HPR) via AGEs path way. Methods : AGEs formation inhibitory activities of PR and HPR measured using bovine serum albumin, glucose, and fructose. To evaluate the protective effects of PR and HPR in diabetic rats induced with streptozotocin (STZ) and methyl glyoxal (MGO), SD rat were distributed into four groups. Normal rats (Nor), AGEs-induced rats (Con), AGEs-induced rats treated with 100 mg/kg PR(PR), AGEs-induced rats treated with 100 mg/kg HPR (HPR). To induce AGEs, streptozotocin (50 mg/kg) was administered intraperitoneally and after 3 days administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of HPR inhibited AGEs in skin tissues compared with PR. The increased reactive oxygen species (ROS) levels in the serum were diminished by HPR treatment. The analyses of kidney and skin tissues proteins indicated that HPR treatment effectively reduced AGEs related protein levels as compared to that by PR treatment. Also, HPR decreased anti-oxidant related protein levels in skin tissues such as catalase, glutathione peroxidase. Moreover, it inhibited the reduction of COL1A2 by decreasing MMP-1. Conclusion : Based on these results, it was suggested that PR and HPR could have Improving effects on wrinkle formation. These evidences provide useful information for the development wrinkle formation treated agent.
