The antidiabetic efficacy of Enicostemma littorale Blume (chhota chirayata) aqueous extract was examined in newly diagnosed non-insulin-dependent diabetes mellitus (NIDDM) patients taking only the extract and was administered as two divided doses, half an hour before meal as 5g of aqueous extract per single dose. Out of the 20 patients volunteered, 11 successfully completed the 2 month trial and a significant decrease in fasting & postprandial blood glucose and glycosylated haemoglobin levels were observed along with a significant improvement in the antioxidant parameters of the patients. There was also a significant increase in serum insulin levels in 7 patients after extract treatment as compared to levels before treatment. Serum total cholesterol and serum triglyceride levels were decreased significantly with a significant increase in serum HDLCholesterol levels. Other vital parameters remained stable and no side effects were observed. This is the first report showing the hypoglycemic, antioxidant and hypolipidemic properties of the aqueous extract of E. littorale Blume in non-insulin dependent diabetes mellitus patients.

Objectives: This study was conducted to analyze the single-dose toxicity and the safety of Mahwangcheonoh pharmacopuncture extracts. Methods: Six-week-old Sprague-Dawley rats were used for this study. Doses of Mahwangcheonoh pharmacopuncture extracts were set at 0.25 mL (low-dose), 0.5 mL (medium-dose) and 1.0 mL (high-dose) for the test groups. A dose of 1.0 mL of normal saline solution was set for the control group. During 14 days, general symptoms, mortalities, and changes in hematology, blood biochemistry and histopathology of all rats were observed. Results: No death was observed in all test groups. Any abnormal symptom was not observed in all of the groups. No significant changes in weight between the control group and the test groups were observed. In addition, no significant differences in the hematology signs, the blood biochemistry levels and the histopathological signs related to the Mahwangcheonoh pharmacopuncture extracts injection were observed. Conclusion: The findings of this study indicate that Mahwangcheonoh pharmacopuncture at doses of 1.0 mL or less may be consider safe and non-toxic. So, it can be used for therapy of obesity sufficiently. But further studies on this subject must be performed to confirm and verify this conclusion.

Objective : This study examined whether Yangsung program (oriental psychological weight regulation model based on Confucian ideas) is effective on weight loss, self esteem, three factor on eating questionnaires(restraint eating, disinhibition and hunger), distortion of body-image and biochemistry of blood. Method : 23 women were assigned randomly into 2 groups; experimental group(n=10) and control group(n=13). Experimental group had 7 personal sessions consisting of personal Yangsung therapy, meditation, general diet and exercise education. Control group had personal sessions with general diet and exercise education once a week for 6 weeks. All subjects were weighed and evaluated with Rosenberg self esteem scale, distortion of body-image, biochemistry of blood and three factor eating questionnaires at the beginning and end of the program. Result : There is significant difference between two groups in changes of self esteem, disinhibition and hunger(p<0.05). There is no significant difference in weight reduction and BMI between two groups. Conclusion : This study showed a new possibility of unique psychological program for obesity characterized by its philosophical context.

Effect of chemical stress of daily administration of glucocorticoid (dexamethasone @0.125 mg./calf/day) injections on plasma zinc levels, Zn status of body tissues and its distribution in sub cellular fractions, was studied in neonatal buffalo calves. Daily i/m injections of dexamethasone, starting at the completion of 1 week of age and continued till 8th week, led to a significant decline in plasma Zn concentration from 3rd week onwards, which then persisted throughout the rest of the experimental period. In control group, liver had the highest concentration of zinc, followed by heart, muscle, spleen, kidney and testis. In all these tissues, cytosolic fractions had the highest (>60%) zinc levels followed by nuclear, mitochondrial and microsomal fractions. In dexamethasone treated calves, there was a significant increase in the Zn uptake by the tissues of liver and muscle. This increase in zinc concentration was observed in all the sub cellular fractions of liver and muscle, however about 80% of this increase was in cytosolic fraction. It was concluded that glucocorticoid-induced stress caused increase in Zn levels of liver/muscles and decrease in blood plasma zinc, thus indicating a redistribution of Zn in body.

We previously reported that the exogenous administration of cumambrin A, a sesquiterpene lactone from the dried flowers of Chrysanthemum boreale Makino has a pharmacological effect on normalization of blood pressure in the spontaneously hypertensive rats (SHR). In the present study, we further investigated the effect of cumambrin A on the relaxation of phenylephrine-induced precontracted rat aortic artery rings. The potency of cumambrin A was than compared to verapamil, a well known $Ca^{2+}-channel$ blocker. The results demonstrate that the isolated rat aortic arteries are relaxed to basal tension at a concentration of $5{\times}10^{-5}\;M$ cumambrin A treatment. The results also show that the phenylephrine-induced contraction is inhibited by a pretreatment of cumambrin A. Co-treatment of cumambrin A and verapamil showed a strong synergetic effect on the relaxation of rat aortic artery rings. Thus, these data demonstrate that cumambrin A is a potent relaxant of rat aortic smooth muscle and suggest that cumambrin A modulates intracellular or extracellular $Ca^{2+}$ mobilization.

A polysaccharide with antithrombin activity in Manda$^{(R)}& (PAM) was purified via procedures comprising three major steps, i.e. fractional precipitation with ethanol, anion exchange chromatography, and gel permeation chromatography. PAM showed a symmetrical peak on size exclusion HPLC, as assessed by refractive index, and behaved as a single band on cellulose acetate electrophoresis. The average molecular mass was estimated to be 222 kDa by gel filtration. PAM was found to be a sulfated heteropolysaccharide that contains sulfate group (20.5%, w/w) and uronic acid moiety (7.1 %, w/w) in addition to neutral sugar consisting of fucose, xylose, mannose, galactose, and glucose in a molar ratio of 1.00 : 0.35 : 0.28: 0.22 : 0.15. This polysaccharide appeared to inhibit blood coagulation via the intrinsic pathway in a dose-dependent pattern. The clotting of fibrinogen by thrombin was also significantly mitigated by the presence of PAM.

The polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities using the melanoma B-16-derived metastatic tumors were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor metastatic inhibitory activities (inhibition ratio 60 and 80% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 85 and 70%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 90 and 95% of inhibition. When the effects of polysaccharides on hypersensitivity were examined, the inhibitory activities were not markedly observed in oral administration, indicating that the polysaccharides are directly acting to immune system. Also, the polysaccharides increased the number of circulating blood leukocytes and total peritoneal exudate cells. Although implantation of tumor cells greatly decreased the productivity of antibody (antibody-mediated) and T lymphocyte reactivity (delayed-type) as 6.3 from 9.3 and 5.9 from 7.7, represented by the increase of footpad thickness, respectively. the polysaccharides elevated the reactivity of T lymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. Especially, F-2, F-5, F-7 and F-8 remarkably recovered the decreased sensitivity. These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.

Promoter hypermethylation of the runt-related transcription factor 3 (RUNX3) gene is associated with increased risk of hepatocellular carcinoma (HCC). Oxidative stress plays a vital role in both carcinogenesis and progression of HCC. However, whether oxidative stress and RUNX3 hypermethylation in HCC have a cause-and-effect relationship is not known. In this study, plasma protein carbonyl and total antioxidant capacity (TAC) in patients with hepatitis B virus (HBV)-associated HCC (n=60) and age-matched healthy subjects (n=80) was determined. RUNX3 methylation in peripheral blood mononuclear cells (PBMC) of subjects was measured by methylation-specific PCR. Effect of reactive oxygen species (ROS) on induction of RUNX3 hypermethylation in HCC cells was investigated. Plasma protein carbonyl content was significantly higher, whereas plasma TAC was significantly lower, in HCC patients than healthy controls. Based on logistic regression, increased plasma protein carbonyl and decreased plasma TAC were independently associated with increased risk for HCC. PBMC RUNX3 methylation in the patient group was significantly greater than in the healthy group. RUNX3 methylation in hydrogen peroxide ($H_2O_2$)-treated HepG2 cells was significantly higher than in untreated control cells. In conclusion, increase in oxidative stress in Thai patients with HBV-associated HCC was demonstrated. This oxidative increment was independently associated with an increased risk for HCC development. RUNX3 in PBMC was found to be hypermethylated in the HCC patients. In vitro, RUNX3 hypermethylation was experimentally induced by $H_2O_2$. Our findings suggest that oxidative stress is a cause of RUNX3 promoter hypermethylation in HCC cells.

Roles of the vitamin D receptor in etiology of cancers, including colorectal cancer, have been repeatedly stressed in different parts of the world. A case control study aimed to evaluate the relationship between the two was therefore initiated in Kashmir, known both for its increasing incidence of gastrointestinal cancers and deficiency of micro-nutrients especially vitamin D. The study included a total of 617 subjects (312 colorectal cancer cases and 305 controls), with sampling carried out over a period of 5 years. DNA samples from the blood of the subjects were analyzed for start codon Fok I VDR polymorphism. We obtained a 1.3 fold increased risk among individuals homozygous for f variants as compared to subjects homozygous for F allele (odds ratio OR 1.3, 95%CI, 0.861-1.65). Our study also showed statistically significant results when dwelling and tumor location characteristics were stratified with Fok I polymorphism, all of which suggests a possible role of Fok I polymorphism in the etiology of CRC in Kashmir.
