In order to study the effects of Aloe vera treatment on blood glucose level and clinical chemistry in diabetic patients, eight diabetic patients were administered orally with 800 mg of Aloe vera three time a day for three months. The high levels of blood and urine glucose in diabetic patients were significantly reduced by administration of Aloe vera. The increased plasma triglyceride concentration was also significantly reduced by Aloe vera treatment. A little amount of urine bilirubin, hematuria, nitrite, urobilinogen, protein and ketone bodies were detected before treatment, but not detected after Aloe vera treatment. But other blood parameters of clinical chemistry values were not affected by Aloe vera treatment. These data suggest that Aloe vera can be effective in the treatment of the diabetic patients.

Although insulin has been available for the treatment of diabetes mellitus for more than half a centry, the deficiency of conventional insulin therapy for diabetic patients have, to this date, not been satisfactorily overcome by any method. The development of potential delivery systems for insulin is highly important to prevent excessive fluctuation of plasma glucose levels, which results in long term complications in the diabetic. There are three major approaches toward development of glucose responding insulin delivery systems: A bioengineering approach is to devise mechanical components capable of releasing insulin in amounts appropriate to varying blood-glucose requirements. A biological approach relies upon cultured, living pancreatic beta cells encapsulated to constitute an insulin delivery unit. A biochemical approach is to synthesize a stable and biologically active glycosylated insulin that is complementary to the binding sites of lectin. This paper will cover several specific areas, including pancreatic transplantation(total or isolated islet cells), artificial pancreases(bioengineering or biological approach), controlled delivery system, glucose sensitive membrane systems, and a self-regulating insulin delivery system.

Aging process can be explained by many factors. In this study, we counted complete Blood Cells (CBC) such as WBC, Lymphocytes, Monocytes, Granulocytes, RBC, HGB, and HCT of both SAM P6 and SAM P1 during the aging process. Plasma albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea concentrations were also measured at the same time. In addition to these, plasma concentrations of cortisol, total T3, and total T4 were analyzed by Chemiluminescent Immunoassay. There were no change in CBC counts of SAM R1 and SAM P6 during this study. Plasma concentratins of albumin and glucose decreased significantly in SAM R1. However, plasma alkaline phosphatases and creatinine concentration in SAM P6 decreased significantly at 16 week after birth comparing to the control. Total T4 levels were siginificantly increased although cortisol and total T3 concentrations were the same in SAM R1 groups. Especially, the after birth of creatinine, alkaline phosphatase, T4 of SAM P6 at 16 week were significantly different form those of SAM R1. At 12 week after birth, pilose antler extract was given 5g/kg/day p.o. for 0, 7, 14, 21, and 30 days each in both SAM R1 and SAM P6. The RBC, HGB, and HCT levels started to increase significantly from 7 days after the dose at SAM P6 only. Total T4 conectrations were elevated gradually during the study although the antler extract administration did not prevent or inhibit the increase in total T4 concentration during the study. Therefore, the elevation of erythrocytes after administration of the extract needs to be studied in future.

This study was conducted to investigate the effect of exercise training on blood and metabolic variances and genes expressions in hyperlipidemic rats. Three weeks-old male rats were randomly assigned into chow (n=7), high-fat diet (HF, n=7) and HF+exercise (HF+EX, n=7) groups. Exercise training consisted of the treadmill running 5 times per week during 8 weeks (0% grade, 30 min/time for first 4 weeks and 0% grade, 60 min/time the other 4weeks). The levels of triglyceride and total -cholesterol were increased in HF diet compared with chow group, and recovered to level of chow group by exercise training. Plasma glucose and insulin concentrations increased by 40 and 50%, respectively in HF diet compared with chow diet group, and these increases returned to the level of chow group by exercise training (p<.05). Body weight and abdominal fat mass were increased by high-fat diet compared with chow diet, and recovered to level of chow group by exercise training. Long-chain fatty acid oxidation rate and AMPK protein expression was not changed by HF diet, but increased by exercise training compared with high-fat diet (p<.05). UCP3 protein expression was not changed by either high-fat diet or exercise training compared with chow group. There was high correlation between plasma triglyceride and total cholesterol concentrations(p<.01). Plasma triglyceride or total cholesterol level showed correlation with following factors; plasma insulin and glucose levels, body weight, abdominal fat weight, UCP3 protein expression and long-chain fatty acid oxidation rate. These results showed that exercise training on the treadmill recovered hyperlipidemia, hyperglycemia and hyperinsulinemia induced by high-fat diet for 8 weeks. These exercise effects may be related with decreased body weight and abdominal fat mass, and increased long-chain fatty acid oxidation rate.

This study investigated the effects of magnetized water supplementation on blood glucose, DNA damage, antioxidant status, and lipid profiles in streptozotocin (STZ)-induced diabetic rats. There were three groups of 4-week-old male Sprague-Dawley rats used in the study: control group (normal control group without diabetes); diabetes group (STZ-induced diabetes control); and magnetized water group (magnetized water supplemented after the induction of diabetes using STZ). Before initiating the study, diabetes was confirmed by measuring fasting blood glucose (FBS > 200 dl), and the magnetized water group received magnetized water for 8 weeks instead of general water. After 8 weeks, rats were sacrificed to measure the fasting blood glucose, insulin concentration, glycated hemoglobin level, degree of DNA damage, antioxidant status, and lipid profiles. From the fourth week of magnetized water supplementation, blood glucose was decreased in the magnetized water group compared to the diabetes group, and such effect continued to the 8th week. The glycated hemoglobin content in the blood was increased in the diabetes group compared to the control group, but decreased significantly in the magnetized water group. However, decreased plasma insulin level due to induced diabetes was not increased by magnetized water supplementation. Increased blood and liver DNA damages in diabetes rats did significantly decrease after the administration of magnetized water. In addition, antioxidant enzyme activities and plasma lipid profiles were not different among the three groups. In conclusion, the supplementation of magnetized water not only decreased the blood glucose and glycated hemoglobin levels but also reduced blood and liver DNA damages in STZ-induced diabetic rats. From the above results, it is suggested that the long-term intake of the magnetized water over 8 weeks may be beneficial in both prevention and treatment of complications in diabetic patients.

Purpose: Lipopolysaccharide-binding protein (LBP) is a 65-kDa acute phase protein, derived from the liver, which is present in high concentrations in plasma. Data regarding the association between circulating plasma LBP levels and obesity-related biomarkers in the pediatric population are scarce. We aimed to determine whether there was a difference in plasma LBP levels between overweight/obese and normal-weight adolescents and to assess the correlation of circulating LBP levels with anthropometric measures and obesity-related biomarkers, including insulin resistance, liver enzyme levels, and lipid profiles. Methods: The study included 87 adolescents aged 12-13 years; 44 were overweight/obese and 43 were of normal-weight. We assessed anthropometric and laboratory measures, including body mass index (BMI), blood pressure, insulin resistance, liver enzyme levels, and lipid profiles. Plasma LBP levels were measured using an enzyme-linked immunosorbent assay. Results: The mean age of the participants was $12.9{\pm}0.3$ years. Circulating plasma LBP levels were significantly increased in overweight/obese participants compared with those in normal-weight participants ($7.8{\pm}1.9{\mu}g/mL$ vs. $6.0{\pm}1.6{\mu}g/mL$, P<0.001). LBP levels were significantly and positively associated with BMI, systolic blood pressure, aspartate aminotransferase, alanine aminotransferase, total cholesterol, low density lipoprotein-cholesterol, fasting glucose and insulin, and insulin resistance as indicated by the homeostatic model assessment of insulin resistance (HOMA-IR) (all P<0.05). In multivariate linear regression analysis, BMI and HOMA-IR were independently and positively associated with plasma LBP levels. Conclusion: LBP is an inflammatory biomarker associated with BMI and obesity-related insulin resistance in adolescents. The positive correlation between these parameters suggests a potentially relevant pathophysiological mechanism linking LBP to obesity-related insulin resistance in adolescents.

Aim: To investigate the effect of hyperglycemia and hyperinsulinemia on prostate cancer risk. Materials and Methods: This hospital based study was carried out using data retrieved from the register maintained in the Department of Biochemistry of a tertiary care hospital of Kathmandu, Nepal between $31^{st}$ December, 2011 and $31^{st}$ October, 2013. The variables collected were age, serum cholesterol, serum calcium, PSA, fasting blood glucose, serum insulin. Analysis was performed by descriptive statistics and testing of hypothesis using Excel 2003, R 2.8.0, Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results: Of the total 125 subjects enrolled in our present study, 25 cases were of PCa and 100 were healthy controls. The mean value of fasting plasma glucose was 95.5 mg/dl in cases of prostatic carcinoma and the mean value of fasting plasma insulin was $5.78{\mu}U/ml$ (p value: 0.0001*). The fasting insulin levels ${\mu}U/ml$ were categorized into the different ranges starting from ${\leq}2.75$, >2.75 to ${\leq}4.10$, >4.10 to ${\leq}6.10$, > $6.10{\mu}U/ml$. The maximum number of cases of prostatic carcinoma of fasting insulin levels falls in range of > $6.10{\mu}U/ml$. The highest insulin levels (> $6.10{\mu}U/ml$) were seen to be associated with an 2.55 fold risk of prostatic carcinoma when compared with fasting insulin levels of (< $2.75{\mu}U/ml$). Conclusions: Elevated fasting levels of serum insulin appear to be associated with a higher risk of prostate cancer.

This study was performed to investigate the effect of cyclosporine (CsA) on glucose tolerance and peripheral insulin sensitivity in normal Sprague-Dawley rats. After daily treament of CsA (10 mg/kg, i.p.) for two weeks, glucose tolerance tests were carried out by the treatment of glucose (Glu, 2 g/kg, i.p.) alone or in conjunction with exogenous insulin (Ins; human regular insulin, 5 U/kg, s.c.) and measured the decrement of area under the time-plasma glucose concentration curve ($AUC_{o\longrightarrow120}$; g.min/ml) by the trapezoidal rule. The rats were divided into three groups (Glu- (Control), Ins+Glu- and CsA+Ins+Glu-, n=7 in each group). The $AUC_{o\longrightarrow120}$ of the CsA+Ins+Glu-group was significantly (p<0.01) lower than that of Glu-group (61.0% of control) and significantly (p<0.05) higher than that of Ins+Glu-group (197.4% of Ins+Glu-). The CsA+Ins+Glu- grou showed higher levels of maximal blood glucose concentration and higher $AUC_{o\longrightarrow120}$ than those of Ins+Glu-group in normal rats. Besides direct pancreatic toxicity of CsA previously reported (Hahn et al., 1972), these results suggest that CsA also make the possibility to induce peripheral insulin insensitivity and glucose intolerance in normal rats.

본 연구에서는 methanol로 온시여과 후 계통분획하여 감압농축하여 얻은 참마의 $H_2O$ 분획물을 vitamin E와 함께 STZ으로 당뇨를 유발시킨 흰쥐에게 14일간 경구투여한 후 혈당과 지질대사에 미치는 영향을 실험하여 다음과 같은 결과를 얻었다. 당뇨대조군은 당뇨로 인한 대사상의 변화로 정상군과는 다른 대사적인 차이를 나타내었다. 당뇨대조군과 참마와 vit. E 투여에 따른 당뇨실험군에서는 식이의 섭취와 식이효율에는 유의적인 차이가 없었다. 체중의 변화는 14일 후 참마와 vit. E 병용투여군에서 정상군과 유사한 수준이었고 전 실험기간동안의 체중의 변화는 실험군간에 점차 낮아지는 경향을 보였으나 유의적인 차이를 보이지 않았다. 장기의 무게를 체중 100 g 당으로 환산하였을 때 심장의 무게는 당뇨실험 군 중 vit. E 투여군에서 낮게 나타났으며 췌장의 무게는 당뇨대조군에 비해 모든 실험군에 낮게 나타났으나 유의적인 차이는 보이지 않았다. 혈장 단백질 수준은 당뇨대조군에 비해 당뇨실험군 모두에서 높게 나타났다. 혈장 인슬린의 함량은 모든 실험군에서 유의적인 차이를 보이지 않았으나 참마투여군에서 약간 높은 수준이었다. 혈장 포도당 수준도 당뇨대조군에 비해 당뇨실험군에서 낮아지는 경향을 보였다. 혈장지질 수준에 미치는 영향을 보면 중성지방과 유리지방산 함량은 당뇨대조군에 비해 vit. E군에서 낮은 수준을 보였으며 HDL-cholesterol 수준은 모든 당뇨실험군에서 높게 나타났다. 혈장 cholesterol 수준의 경우도 당뇨대조군과 실험군에서 큰 차이는 없었으나 vit. E군에서 낮은 수준을 보였다. AST및 ALT활성도는 실험군 간에 큰 차이를 보이지 않았다. 본 연구 결과 참마의 $H_2O$ 분획물은 vitamin E 병용 투여시 지방대사와 인슬린활성에 작용하여 혈당강하에 영향을 주는 생리활성성분을 함유하는 식품으로 당뇨식이처방에 유용하리라 생각되며 vitamin E 보충에 의한 대사적인 변화에 대하여 더 구체적인 생화학적인 연구가 이루어져야 될 것으로 여겨진다.

The purpose of this study was to investigate the relationship among plasma leptin, lipid profiles, insulin levels, and percentage of body fat of 72 schoolchildren from Obese Clinic Center in Seoul. The subjects divided into two groups: 39 obesity children [obesity index greater than $20\%$] who did not have a discernable medical cause of their obesity and 33 children with a obesity index less than $20\%$. The mean age, height, and obesity index of the subjects were 10.4 years, 144.0 cm, and $21.3\%$, respectively. The mean glucose and insulin levels of the obese children were 80.5 mg/dl and $13.3\;{\mu}IU/mL$ and those of the non obese children were 82.0 mg/dl and $4.2\;{\mu}IU/mL$, respectively. Obese children had significantly (p<0.05) higher level of total cholesterol, triglyceride, VLDL-cholesterol, LDL-cholesterol, and insulin concentration than non-obese children. However obese children had a lower level of HDL-cholesterol than non-obese children. Plasma leptin level were also positively correlated with BMI (p<0.000l), body fat (p<0.0001), tricep skinfold thickness (p<0.0001), mid arm circumference (p<0.0001), and waist hip ratio (p<0.0001). Plasma leptin showed a significantly positive correlation with insulin (p<0.0001), total cholesterol (p<0.0001), LDL-cholesterol (p<0.0001), and triglyceride (p<0.0001) levels, however, it was negatively correlated with HDL-cholesterol (p<0.0001) levels. In conclusion, the concentration of leptin in the blood is significantly correlated with the amount of body fat, BMI, plasma insulin, and plasma lipid profiles.
