  • The object of this study was to observe the effects of Hwanggeum-tang (HGT) aqueous extracts on Streptozotocin-induced rat's diabetes and related complications. Three different dosages of HGT extracts were orally administered oncea day for 28 days from 3 weeks after Streptozotocin treatment (60 mg/kg, single intraperitoneally administered). All the rats were checked at 3 weeks after Streptozotocin treatment as follows. Changes on the body weight, blood glucose level, kidney weight, serum BUN and creatinine level, liver weight, serum AST and ALT level, serum LDL, HDL, triglyceride and total cholesterol level were observed with changes on the pancreatic MDA content and GSH content. The results were compared with a potent antioxidant silymarin 100 mg/kg in which the effects on Streptozotocin-induced diabetes and related complications were already confirmed. As results of Streptozotocin-injected diabetes and related complications, dramatical decreases on the body weight, increase of the kidney and liver weight, increase of serum BUN, creatinine, AST, ALT, LDL, triglyceride, total cholesterol level and decreases of serum HDL level were detected in streptozotocin control as compared with intact control. In addition, marked increases of pancreatic MDA content and decreases of GSH content were also detected in streptozotocin control as compared with intact control. However, these diabetes and related complications, and inhibition of antioxidant effects induced by Streptozotocin were inhibited by 28 days continuous treatment of 50, 100 and 200 mg/kg of HGT extracts in the present study. HGT have favorable effects on the diabetes and various diabetic complications. Therefore, more detail mechanism studies should be conducedin future with the efficacy tests of individual herbal composition of HGT and the screening of the biological active compounds in herbs.

  • We plan to make the standardization of the pattern identifications for stroke and differentiate them by tongue diagnosis. We make a case report form which has questionnaires for tongue diagnosis in stroke patients. And we collected cases from the multi center network which consists of twelve university hospitals and one local hospital. The cases confirmed by diagnosis of medical specialists and residents are 321 cases. They are divided into Qi Defficiency 30.84%, Dampness& Phlegm 25.55%, Fire & Heat 22.43%, Eum Defficiency 18.69% and Blood Stasis 2.49%. We analyzed the markers which classified into the color of tongue body, the color of fur, the quality of fur, the dryness of tongue, the shape of tongue. To make a stroke pattern identification standard, we must try variable ways.

  • Etiological studies of diabetes and its complications showed that oxidative stress might play a major role. Therefore, many efforts have been tried to regulate free oxygen radicals for treating diabetes and its complications. Cheonghyul-san has been known to be effective for the antidiabetic, antihyperlipidemic and antiobesitic prescription, and composed of four crude herbs. In male ob/ob mouse with severe obesity, hyperinsulinemia, hypergiycemia, hyperlipidemia, the acting mechanisms of Cheonghyul-san were examined. Mice were grouped and treated for 5 weeks as follows. Both the lean (C57/BL6J black mice) and diabetic (ob/ob mice) control groups received standard chow. The experimental groups were fed with a diet of chow supplemented with 7.5, 15 and 30 mg Cheonghyul-san per 1 kg of body weight for 14 days. The effects of Cheonghyul-san extract on the ob/ob mice were observed by measuring the serum levels of glucose, insulin, lipid components, and the kidney levels of reactive oxygen species (ROS), MDA+HAE, GSH and also the enzyme activities involved in polyol pathway. Cheonghyul-san lowered the levels of serum glucose and insulin in a dose dependent manner. Total cholesterol, triglyceride and free fatty acid levels were decreased, while the HDL-cholesterol level was increased, in Cheonghyul-san treated groups. Renal aldose reductase and sorbitol dehydrogenase activities were increased in the ob/ob mice, whereas those were inhibited in the Cheonghyul-san-administered groups. Cheonghyul-san inhibited the generation of ROS in the kidney. Finally, MDA+HAE level was increased and the GSH level was decreased in the ob/ob mice, whereas those were improved in the Cheonghyul-san-administered groups. The results suggested that Cheonghyul-san exerted the antidiabetic and antihyperlipidemic activities by regulating the activities of polyol pathway enzymes, scavenging ROS, regulating the MDA+HAE and GSH levels in the ob/ob mice.

  • Extract of Acanthopanax senticosus has recently been demonstrated to possess significant antidiabetic potential, in accordance with the traditional use of this plant as an antidiabetic natural health product. The present study evaluated the effects of fermented extract (FE) of this plant on glucose-stimulated insulin secretion, glucose uptake, and streptozotocin-induced type 1 diabetes model. A 3 h pretreatment with FE prevented $IL-1{\beta}$ and $IFN-{\gamma}$ toxicity in isolated rat islets. However, it did not affect insulin-stimulated glucose uptake in C2C12 myotubes. In addition, pretreatment of mice with FE blocked the destruction of streptozotocin-induced islets and the development of type 1 diabetes. FE reduced blood glucose level, increased insulin secretion, and improved glucose tolerance in streptozotocin-treated mice, whereas nonfermented extract (NFE) had moderate effects. Immunohistochemical staining for insulin clearly showed that pretreatment with FE blocked the STZ-induced islets destruction and restored the number of islet cells that secreted insulin to the level of the control. Although the active principles and their mechanisms of action remain to be identified, FE may nevertheless represent a novel complementary therapy and a source of novel therapeutic agents against type 1 diabetes mellitus.

  • This study is to develop a standard tool for pattern identifications in Korean Medicine for Lung Cancer. The advisor committee for this study was organized by 12 Korean Medicine professors from the Korean Association of Traditional Oncology. The item and structure of instrument were based on review of published literature. We took the consultation twice from the advisor committee and additional advices by e-mail correspondences. We divided the symptoms and signs of lung cancer into 6 pattern identifications. - lung spleen both deficiency (肺脾兩虛), lung kidney both deficiency (肺腎兩虛), dampness phlegm obstructing the lung (濕痰蘊肺), qi stagnation blood stasis (氣滯血瘀), yin deficiency toxin heat (陰虛毒熱), and heat toxin accumulation (熱毒蘊結). We obtained the mean weights which reflected the standard deviations from each symptoms of the 6 pattern identifications which were scored on a 5-point scale by 12 experts. We designed the Korean medicine pattern identification tool for lung cancer. It was composed of 57 questions in the question-and-answer format. Though there are some limits that this study is not proved about validity and reliability, the instrument is meaningful and expected to be applied to the subsequent research.

  • Gilbert's syndrome is one that shows a benign course with intermittent unconjugate hyperbilirubinemia without any evidence of hepatobiliary tract disease or hemolysis. It is often found in a health examination or blood laboratory test by chance. In particular, patients who are taking drugs, including herbal medicine should be careful for their medication due to the possibility of associations with changes in liver function because of drug metabolism, sometimes they have to quit the use of the medication for a certain period and often they should get an additional test. Two male patients increased serum total bilirubin level without other systemic symptoms in screening test for clinical herb medicine pharmacokinetics study. Therefor they was diagnosed with suspected Gilbert's syndrome. They had been calory deprivation test with 24 hours fasting state. They also performed liver function test and ultrasonogram for evaluation of hepatobiliary tract disease. Total serum bilirubin was markedly increased, especially unconjugate bilirubin level higher over the two times than base line after they had been calory deprivation for 24 hours, They was not found another abnormality all laboratory results and physical examination. This study is a report on two cases of hyperbilirubinemia, diagnosed as Gilbert's syndrome, which were found in the process of a clinical pharmacokinetic study of a decoction of medicinal herbs.

  • This study was performed to investigate using of herbal medicine based on pattern identification of symptoms, such as Qi deficiency pattern, Yin deficiency pattern, Phlegm -dampness pattern, Static blood pattern, Fire-heat pattern. These patterns settled by Korean Standard Differentiation of the Symptoms and Signs for Stroke in 2005. This study was done with 177 patients in Daejeon University Oriental Medical Hospital in the period of November 2006 to July 2007. Among the five types of pattern identification, Phlegm -dampness pattern showed significantly high frequency especially in 3 weeks after stroke. The sort of herbal medicine was 43 and Dodamhwalhyoel-tang(26.61%), Sunhwanki 1 hobang(14.52%), Banhabaekchulcheonma-tang(4.84%), Ansinchongnoi-tang(4.84%), Chongryuldodam-tang(4.03%) were most frequently used. Especially Dodamhwalhyoel-tang showed significantly high frequency in 2 weeks after stroke. Based on these results, it is suggested that more practical Korean Standard Differentiation of the Symptoms and Signs for Stroke would be established through continuous clinical studies by giving weight on relationship between herbal medicine and pattern identification.

  • Nigella sativa (N. sativa, family Ranunculaceae) is a medicinal plant that has been widely used for centuries throughout the world as a natural remedy. A wide range of chemical compounds found in N. sativa expresses its vast therapeutic effects. Thymoquinone (TQ) is the main component (up to 50%) in the essential oil of N. sativa. Also, pinene (up to 15%), p-cymene (40%), thymohydroquinone (THQ), thymol (THY), and dithymoquinone (DTQ) are other pharmacologically active compounds of its oil. Other terpenoid compounds, such as carvacrol, carvone, 4-terpineol, limonenes, and citronellol, are also found in small quantities in its oil. The main pharmacological characteristics of this plant are immune system stimulatory, anti-inflammatory, hypotensive, hepatoprotective, antioxidant, anti-cancer, hypoglycemic, anti-tussive, milk production, uricosuric, choleretic, anti-fertility, and spasmolytic properties. In this regard, we have searched the scientific databases PubMed, Web of Science, and Google Scholar with keywords of N. sativa, anti-cancer, apoptotic effect, antitumor, antioxidant, and malignancy over the period from 2000 to 2017. The effectiveness of N. sativa against cancer in the blood system, kidneys, lungs, prostate, liver, and breast and on many malignant cell lines has been shown in many studies, but the molecular mechanisms behind that anti-cancer role are still not clearly understood. From among the many effects of N. sativa, including its anti-proliferative effect, cell cycle arrest, apoptosis induction, ROS generation, anti-metastasis/anti-angiogenesis effects, Akt pathway control, modulation of multiple molecular targets, including p53, p73, STAT-3, PTEN, and $PPAR-{\gamma}$, and activation of caspases, the main suggestive anti-cancer mechanisms of N. sativa are its free radical scavenger activity and the preservation of various anti-oxidant enzyme activities, such as glutathione peroxidase, catalase, and glutathione-S-transferase. In this review, we highlight the molecular mechanisms of apoptosis and the anti-cancer effects of N. sativa, with a focus on its molecular targets in apoptosis pathways.

  • Objective: The present study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin and steroid-free bovine follicular fluid, respectively, on reproductive fecundity out of breeding season in Iraqi Awassi ewes. Methods: Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, and used for immunization of male rabbits for obtaining steroid free bovine follicular fluid (SFBFF) antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each). At day 38 of experiment, ewes were treated with intra-vaginal MPA sponge (60 mg for 12 days). At days 0, 28, and 50, ewes were treated with 4, 2, and 2 mL of normal saline (control; C-ve), 400, 200, and $200{\mu}g$ of ovalbumin (C+ve), 400, 200 and $200{\mu}g$ of inhibin (SI group), respectively, and 4 mL of normal saline at day 0, and 4 and 2 mL of SFBFF antiserum at days 28 and 50, respectively, (AI group). After mating with Awassi rams, pregnancy and embryo number were diagnosed, at day 38 of pregnancy, using ultrasonography. Blood samples were collected at days 30, 60, 90, and 120 of pregnancy, for assessment of estradiol-$17{\beta}$ (E2) and progesterone (P4) levels. After parturition, numbers of delivered lambs were recorded. Results: The results revealed significant increase of P4 and significant decrease of E2 levels in SI and AI pregnant ewes than controls at days 30, 60, 90, and 120. Newborn number increased significantly in SI and AI treated than control ewes. Conclusion: Active or passive immunization against endogenous inhibin could augment reproductive fecundity out of breeding season in Iraqi Awassi ewes.
