Controlling dietary behaviors and health-related lifestyle habits is important to manage non-insulin dependent diabetes mellitus (NIDDM). If NIDDM is not treated properly, the prevalence of macro-vascular complications (MC) may increase. The goal of NIDDM therapy is to maintain normal concentrations of blood glucose and lipid profiles by having regular meals, controlling alcohol drinking, quitting smoking, and performing physical exercise regularly. This study was performed to investigate the dietary and health-related lifestyle habits and blood parameters of NIDDM patients of both genders and compared these characteristics between the patients with and without MC. Our results show that the subjects with MC compared to without MC and the female patients than the males controlled their diets more regularly, tended to regulate the number of meals better, and smoke less than those without MC. Although plasma lipid profiles were not significantly different between the genders and between the subjects with and without MC, the men had higher blood glucose and plasma tHcy concentrations than the women and plasma tHcy concentration was higher in the female subjects without MC. These results imply that the male patients of NIDDM without MC might have more problems in maintaining their blood glucose. In addition, smoking may be the most important life-style factor influencing some blood parameters like blood glucose, HbAlc, and total cholesterol in the NIDDM patients.

Purpose: This study was to determine the effect of oral vitamin C supplements on blood sugar and antioxidative status in Types II diabetes mellitus patients. Method: Data for the study were collected from June 24 to August 31, 2001. Participants(31) took 1g/day vitamin C for 4 weeks, after a 1 - week taking no Vitamin C, followed by Vitamin C 3g/day for 4 weeks. A baseline blood sample was obtained following a 12hour overnight fast and at the end of each 4week Vitamin C administration. Blood samples were taken for plasma vitamin C concentration, fasting blood sugar, HbA1c, superoxide scavenging activity and hydrogen peroxide scavenging activity. The data were analyzed by SPSS for repeated measures ANOVA. Result: Plasma vitamin C concentration was significantly increased over dose(F=3.316, p=.043). Fasting blood sugar and HbA1c was significantly decreased over dose(F=13.192, p=.000; F=11.995, p=.000). Superoxide scavenging activity and hydrogen peroxide scavenging activity was significantly increased over dose(F=486.138, p=.000; F=177.704, p= .000). Conclusion: The results suggest that megadose vitamin C supplementation may have a beneficial effect in diabetes mellitus patients on both glycemic control and antioxidant status. Thus dietary measures to increase plasma vitamin C may be an important health strategy for reducing the compliance of diabetic patients

Objectives : CRATAEGII FRUCTUS(山査) is known as the substance which delays aging by the antioxidant effects. The purpose of this study is to investigate the effects of CRATAEGII FRUCTUS(山査) on antioxidant enzyme activities such as Thiobarbituric acid reactive substance(TBARS), Superoxide dismutase(SOD), Catalase(CAT), Glutathione peroxidase (GSH-px) in rat erythrocytes and blood plasma. Methods : Sprague-Dawley rats were divided into 3 groups, Normal group (supplied enough water and feeds only, Normal Group), D-galatose administered group(injected D-galatose 50mg/kg, 1time/day for 6 weeks, Control Group) and CRATAEGII FRUCTUS(山査) administered group (D-galactose 50mg/kg and CRATAEGII FRUCTUS(山査) extracts 85.0mg/200g 1time/day for 6 weeks, SS Group). Rats were sacrificed and TBARS, SOD, CAT, GSH-px, neutral fat and cholesterol were measured in rat erythrocytes and blood plasma. Results : There was no significant difference in the level of TBARS in the blood plasma between each experimental group. Red blood cell SOD activities were significantly different in each group. They were significantly decreased in the Control group compared to those of Normal and there was an increasing phenomenon in the SS group compared to the Control group. There was a significant difference in the activities of the red blood cell - glutathione peroxides in each group. There was a significant increase in the SS group compared to the Control group. Red blood cell catalase activities was no significant difference in each group. Plasma total lipid concentration was significantly different in each group. It was significantly increased in the Control group compared with the Normal group and it was decreasing in the SS group compared to the control group. Plasma triglyceride was not significantly different in each group. Plasma total cholesterol and Plasma HDL -cholesterol concentrations in the blood plasma were not significantly different in each group. Conclusions : According to the above results, it is considered that CRATAEGII FRUCTUS(山査) is effective in inhibiting lipid peroxides and increasing the activities of antioxidative(anti aging) enzyme in D-galactose induced aging rat.

Lead (Pb) is a metal that is generally considered to be toxic to the cardiovascular system. Pb-exposed animals display the evidence of increased oxidative stress and hypertension. The current study was designed to examine whether Korean red ginseng (KRG) has protective effects against Pb-induced hypertension and oxidative stress in Pb-exposed rats. Male Sprague-Dawley rats were randomly assigned to Pb exposure or control groups. KRG was administered in drinking water at a concentration of 100 mg/kg/day; the control group received plain drinking water. Animals in the Pb-exposed groups were provided with drinking water containing 100 ppm Pb acetate for 12 weeks. Blood pressure, plasma glutathione, blood Pb concentration, and hematologic data, such as red blood cell quantity, were determined. Pb poisoning was assessed by measuring the blood Pb concentration. Pb exposure (100 ppm) for 12 weeks resulted in a marked rise in systolic blood pressure and blood Pb concentration, as well as a significant reduction in plasma glutathione levels and red blood cell quantity. Other measurements, such as heart rate, body weight, and white blood cell quantity, were unchanged. Treatment with KRG significantly lowered blood pressure, raised plasma glutathione and increased red blood cell numbers in Pb-exposed animals; it also had no effect on heart rate, body weight, or white blood cell quantity. However, the elevated blood Pb concentration was not reduced by treatment with KRG (100 mg/kg). Taken together, these data indicate that treatment with KRG in Pb-exposed animals can reduce oxidative stress and lower blood pressure, suggesting that KRG might be protective against Pb-exposed hypertension and oxidative stress.

Soluble glass bolus with selenium (Se), copper (Cu) and cobalt (Co) was administered intraruminally to Philippine grazing does fed under backyard farming conditions to determine its effect on blood mineral status. Forty-five does were dosed with SGB intraruminally every 6 months, whereas 15 were without SGB during this experimental period of 10 months. Blood of does in both treatment groups were collected every other month and blood Se, plasma Cu, Ca, P and Mg were determined in this study. All does did not show clinical Se, Cu, Ca, P or Mg deficiency during this experimental period. Selenium concentration of treated does increased (p<0.01) after beginning of this experiment, whereas the level of control does decreased slowly (p<0.01). Two months after SGB administration, all treated does had higher blood Se than the lower limit of $20{\mu}g/l$ suggested by NRC (1981), whereas some control does had lower blood Se concentration than the lower limit of $20{\mu}g/l$. On the other hand, plasma Cu concentration of treated does started to increase more remarkably than control does 4 months after this experiment had started although the difference was insignificant. There were no significant differences between plasma Ca, P or Mg concentration of does in both treatment groups. Soluble glass bolus had no harmful effects on plasma macro mineral concentrations of grazing does. This study showed that SGB was available as mineral supplement to improve imbalances of selected mineral of grazing goats in the traditional backyard conditions in Luzon Island, Philippines.

The effects of fetal number (single or twin) on blood glucose and plasma NEFA during pregnancy and around parturition were studied on ten Alpine ${\times}$ Beetal crossbred goats in their first to third lactation. The animals were divided in-groups 1(carrying single fetus, n=4) and 2(twin fetus, n=6). The samples were drawn on day1 after estrus and then at 14 days interval (fortnight) for 10 fortnights. Around parturition the samples were taken on days -20, -15, -10, -5, -4, -3, -2, -1 prior to kidding and on day 0 and +1, +2, +3, +4, +5, +10, +15, +20 days post kidding. In twin bearing goats the blood glucose concentration continued to increase from 1st until 4th fortnight and thereafter gradually decline from 5th upto 8th fortnight. In single bearing goats there was increase in levels from 2nd upto 4th fortnight and thereafter it declined from 5th uptill 9th fortnight. The difference in sampling interval was highly significant (p<0.01) in both the groups. However the values were higher in single than in twin bearing goats. The plasma NEFA concentration was low in both the groups' upto 4th fortnight and thereafter it is continuously increased upto 9th fortnight. During prepartum period the blood glucose was higher in single than in twin bearing goats. The values were minimum on the day of kidding in both the groups. During postpartum period the values were significantly (p<0.01) higher in twin than in single fetus bearing goats. The plasma NEFA was significantly (p<0.05) higher in twin than in single fetus bearing goats. The blood glucose and plasma NEFA concentration can be used as index of nutritional status during pregnancy and around parturition in goats.

In this paper, the influence of phenytoin and phenobarbical on the changes of brain norepinephrine(NE) content, plasma corticosterone and blood sugar level in mice were studied. The results obtained were summarized as follows: 1) Phenytoin(50 mg/kg) increased the brain NE content but phenobarbital(50 mg/kg) did not affect. The increase of the brain NE content induced phenytoin was potentiated by phenobarbital pretreatment. 2) Phenytoin(25 mg/kg, 50 mg/kg) markedly increased the level of plasma corticosterone but phenobarbital did not affect. The increase of the plasma corticosterone induced by phenytoin was inhibited by phenobarbital pretreatment. 3) Phenytoin(50 mg/kg) markedly increased the blood sugar level but phenobarbital did not affect. The increase of the blood sugar induced by phenytoin was not affected by phenobarbital pretreatment.

The purpose of this study is to determine the effect of oral vitamin C supplements on blood sugar and serum lipid level(total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein) in non-insulin independent diabetes mellitus. The study design was a non equivalent control group pre-test post-test design. Data for the study were collected from June 24 to August 31, 2001. The ninty-five research subject were assigned to experimental group(51) and control group(44). Vitamin C(3g/day) was given to 51 subjects for 4 weeks. Following a 12h overnight fasting, blood sample was obstaind at baseline and at the end of 4week - supplementation. Blood samples were taken for plasma vitamin C concentration, fasting blood sugar, HbA1c and serum lipid level. The pre-equivalent test was used by Chi-squre, t-test and two group's pre and post experimental differences were analyzed by t-tset to compare with each other. The results of this study were as follows ; 1. The difference between the two groups in plasma vitamin C concentration was significant(t=-12.950, p=.000). 2. The difference between the two groups in fasting blood sugar was significant(t=5.293, p=.000). 3. The difference between the two groups in HbA1c was not significant(t=1.758, p=.082). 4. The difference between the two groups in total cholesterol, HDL, LDL was significant(t=3.786, p=.000 ; t=-5.515, p=.000 ; t= 4.169, p = .000). These results suggest that megadose vitamin C supplementation be effective in lowering fasting blood sugar, serum lipids and increasing plasma vitamin C. Thus dietary measures to increase plasma vitamin C may be on important health strategy for reducing the compliance of diabetic patients.

The changes in the red cell volume and the plasma chloride level were measured when the blood $CO_2$ content was altered by equilibration with the atmospheric air or pure $CO_2$ for 20 minutes. The red cell volume was expressed in terms of hematocrit and mean corpuscular volume (M.C.V.). The results obtained were as follows. 1) On equilibration with the atmospheric air, the MCV and the plasma chloride level were $91.6{\pm}1.26\;c.{\mu}$ and $110.7{\pm}6.28mEq/L.$ respectively. 2) On equilibration with pure $CO_{2}$, the MCV and the plasma chloride level were $109.6{\pm}2.0\;c.{\mu}$ and $90.7{\pm}5.17\;mEq/L.$ respectively. 3) When the blood was subjected to equilibration with the atmospheric for air 20 minutes after equilibration with pure $CO_{2}$ for the same period of time the MCV and the plasma chloride level were $89.9{\pm}6.34\;c.{\mu}$ and $100.3{\pm}5.50\;mEq/L.$ respectively. From the above results it can be concluded that an increase of the blood $CO_2$ content in the experimental condition causes definitely a decrease of the plasma chloride level and a concomitant increase of the red cell volume, and that a decrease of the blood content $CO_2$ in the experimental condition causes definitely an increase of the plasma chloride level and a concomitant decrease of the red cell volme. Apparantly there exists a parallel relationship between the extent of the decrease of the plasma chloride level and that of the increase of the red cell volume when the blood $CO_2$ content increased in the experimental condition. When the blood $CO_2$ content decreased, the extent of the decrease of the red cell volume exceeds that of the increase of the plasma chloride level.
