The production of hydrogen peroxide (H2O2) by neutrophilic polymorphonuclear leukocytes (PMN) after stimulation with PMA, FMLP, aggregated IgG and phagocytosis were determined in 36 patients with non-insulin dependent diabetes mellitus (NIDDM). The H2O2 production of PMN after the stimulation was measured using by flow cytometry. The patients were divided into four stages as follows: (1) non-microalbuminuric stage, (2) microalbuminuric stage, (3) proteinuric stage without impairment of renal function (less than 1.2 mg/dl of serum creatinine) and (4) proteinuric stage with impairment of renal function (more than 1.3mg/dl of serum creatinine). The H2O2 production after stimulation with PMA or phagocytosis was significantly higher in patients with NIDDM than normal controls. And also, there is the tendency of an increase in the H2O2 production after stimulation with FMLP or aggregated IgG. This increase of the H2O2 production was observed in all four stages of NIDDM patients after the stimulation, especially in patients with renal failure associated with diabetic nephropathy. These results suggest that reactive oxygen species produced by PMN after stimulation under various conditions may play an important role in the progression and exacerbation of diabetic nephropathy.

Nearly 50% of individuals with type II diabetes mellitus are over the age of 65 years. There are numerous reasons to maintain blood glucose levels below 11.1 nmol/L (200 mg/dl) in older persons, and there are a number of changes often seen with advancing age that persons, and there are a number of changes often seen with advancing age that may interfere with the management of diabetes mellitus, e.g. hypodipsia, anorexia, visual disturbance, altered renal and hepatic function, depression, impaired basoreceptor response and multiple medications. Hyperglycaemia appears to produce cognitive impairment which may lead to poor compliance. It is often difficult to manipulate diet in older people, and in fact dietary changes can lead to severe protein energy malnutrition. High maximum voluntary oxygen intake has been correlated with increased glucose disposal, but there is little evidence that physical exercise can improve diabetic control in the elderly. Oral sulphonylurea hypoglycaemic agents are extremely useful in the treatment of diabetes in these patients, but it should be remembered that they are more liable to develop hypoglycaemia than are younger diabetics. The role of metformin in the management of older diabetic patients is poorly studied. Many older persons can cope well with insulin therapy, but those with visual disturbances often make errors when drawing up insulin and require special attention. Combination therapy of insulin with oral hypoglycaemic agents is not recommended in this group of patients, and serum fructosamine is preferred to glycated haemoglobin to monitor control. Successful management of elderly diabetic patients thus requires an interdisciplinary team approach.

A study was made of the interrelationship of myocardial perfusion with physical working capacity in different types of DM (with the duration of disease from 4 to 8 years without clinical signs of circulatory insufficiency). Rated physical exercise testing in 12 patients with insulin dependent diabetes and 27 patients with noninsulin dependent diabetes as well as in 40 healthy subjects has shown a GTT decrease in diabetes mellitus irrespective of patient's age, sex and body mass to be more marked in noninsulin dependent type and to be closely related to disturbed oxygen supply of the heart and a lowered myocardial reserve. Bicycle ergometric testing combined with 201Tl scintigraphy in 20 patients has shown disorder of perfusion in all the patients irrespective of a diabetes type and duration of disease. Insulin dependent diabetes mellitus was characterized by stable perfusion defects resulting from metabolic derangements, and noninsulin dependent diabetes mellitus was characterized by a decrease in the level of a maximum Tl uptake by the myocardium and transient perfusion defects of ischemic type.

To find out the effect of correction of hyperglycaemia on maximum aerobic power and anaerobic threshold, we studied 40 middle-aged obese men with recently diagnosed type 2 diabetes before and after 3 months diet therapy. Respiratory gas exchange was measured during maximal incremental bicycle exercise test with breath-by-breath technique at rest, at anaerobic threshold and at peak exercise. As a whole group, the diabetic men reached higher work load after therapy (+9 +/- 3 W (mean +/- SEM), p less than 0.01). A weak inverse linear correlation was found between the changes in fasting blood glucose and in maximum oxygen uptake (r = -0.29, p less than 0.05). When the patients were divided into two groups according to the median values in the change in fasting blood glucose, only those men with more than 1 mmol l-1 decrease in fasting blood glucose improved maximum oxygen uptake (+124 +/- 55 ml min-1 or +6%, p less than 0.05). Oxygen uptake at anaerobic threshold did not change significantly. These results suggest that the correction of hyperglycaemia by diet therapy may improve maximal aerobic power in obese men with recently diagnosed type 2 diabetes.

The effect of a 4-month exercise program on measures of cardiovascular disease (CHD) risk was observed in women (mean age = 59.2 +/- 3.9 years) of postmenopausal years with NIDDM, who demonstrated fair to normal control of blood glucose control. The women were randomly assigned to either an exercise (n = 5) or control (n = 5) group. Initially, both groups had a similar body mass index, resting heart rate and blood pressures, blood glucose and hemoglobin A1. After 4 months, the exercise group demonstrated a 32% increase (P less than 0.03) in both absolute and relative maximum oxygen uptake (VO2) while the control group remained unchanged. Significant differences were found between the exercisers and non-exercisers for absolute (F(1,8) 4.94, P = 0.057) and relative (F(1,8) 7.67, P = 0.024) maximum VO2 from pretest to posttest. Body weight (kg) and body fat (%) remained unchanged for both groups. Although total cholesterol was found to be reduced by 13% for the exercise group (P less than 0.03) and 11% for the controls (P less than 0.01), a 15% decrease (P less than 0.03) in high-density lipoprotein (HDL) was observed for the control group, only. Hence, a marked difference (P less than 0.03) in the risk ratio was observed between the exercise and control groups. These data suggest that physical exercise may play an important role in the maintenance of HDL mass and in the reduction of CHD risk factors in women of postmenopausal years with NIDDM.

Non-insulin-dependent diabetes mellitus (NIDDM) is the most common form of diabetes in the civilized world. Its consequences include microvascular and macrovascular disease, both of which appear to evolve from a common background of obesity and physical inactivity. The current study was undertaken in obese patients with NIDDM to see whether improvements could be made in glycemic control as well as in many cardiovascular risk factors (obesity, hypertension, lipid abnormalities, and physical inactivity) that are typical of this condition. Fifteen obese insulin-using patients with NIDDM (average body mass index, 34.0) were treated with a 500-calorie formula diet for eight to 12 weeks. Administration of insulin and diuretics was discontinued at the onset of the study. A eucaloric diet was begun at eight to 12 weeks and maintained until Week 24. A behaviorally oriented nutrition-exercise program was instituted at the beginning of the study. Glipizide or placebo was added (randomized) at Week 15 if the fasting plasma glucose level in patients exceeded 115 mg/dl. Patients lost an average of 22 pounds over the course of 24 weeks. Frequency and duration of physical activity increased significantly from baseline, as did the maximal oxygen consumption rate. Glycemic control by 15 weeks (without insulin) was similar to baseline (with insulin). With the addition of glipizide at Week 15, both fasting plasma glucose and glucose tolerance improved significantly. This improvement was not observed with placebo. In addition, both systolic and diastolic blood pressure decreased by about 10 mm Hg. There were no significant changes in the levels of serum lipids or glycosylated hemoglobin. In conclusion, a multifaceted intervention program, employing weight reduction, exercise, diet, and glipizide therapy, can be instituted in insulin-using patients with NIDDM, with improvement in glycemic control and in certain risk factors (hypertension, obesity, physical inactivity) for cardiovascular disease.

The incidence and prevalence of diabetic neuropathies in Insulin Dependent (IDDM) and Non-Insulin Dependent (NIDDM) Diabetes Mellitus is not known because in previous studies the heterogeneity of diabetes and of the neuropathies was not taken into account, criteria for diagnosis and surveillance for neuropathy were variable, and studies were not prospective or population based. We have begun such prospective epidemiologic studies using a uniform algorithm for the classification of the diabetic disorders and uniform and validated approaches for the assessment of symptoms, neurologic deficits and various quantitative end-points of neural dysfunction. As regards cause, a key question which we are trying to answer is whether hyperglycemia and associated metabolic alterations affect neural tissue directly or whether there is an intervening tissue alteration between metabolic derangement and tissue change. Improved control of hyperglycemia does not appear to be associated with rapid neurologic improvement, possibly arguing for an intervening tissue alteration. The recently observed decrease in nerve oxygen tension and blood flow in streptozotocin diabetes suggests that an alteration of the nerve microenvironment may relate importantly to the cause of diabetic neuropathy.

During the last decades the physical activity drastically was reduced in daily life. Epidemiological and prospective studies suggest that regular physical activity has beneficial effects in prevention of non-insulin dependent diabetes mellitus, and has protective benefit in control of risk factors in coronary artery disease. It increases cardiovascular functional capacity, decreases myocardial oxygen demand and has a blood-pressure lowering effect. In the prevention of obesity together with a proper diet, regular training is the most important factor influencing life-style. Some studies indicate that exercise might promote protection against colon, breast and lung cancers. To maintain good health aerobic exercise with a moderate intensity on a regular basis is recommended.

Sixty-eight cases of non-insulin dependent diabetes mellitus (NIDDM) complicated with nephropathy were randomly divided into two groups: treated group, 35 cases treated with alcohol extraction of Abelmoschus manihot, Gliclazide and Captopril tablets; control group, 33 cases treated with Gliclazide and Captopril tablets, over a period of 8 weeks. The total effective rate in treated and control group were 83.87% and 31.03%(P < 0.01), urinary micro-albumin were 31.7 mg/L and 76.3 mg/L (P < 0.05), proteinuria were 0.41 g/24h and 0.77 g/24h (P < 0.01), blood beta 2-microglobulin were 3317.8 ng/ml and 3473.1 ng/ml (P < 0.05), urinary beta 2-microglobulin were 367.2 ng/ml and 641.5 ng/ml (P < 0.01), urinary N-acetyl-beta-glucosaminidase (NAG) were 26.3 u/L and 66.7 u/L (P < 0.01), plasma lipid peroxide (LPO) were 6.13 nmol/L and 8.78 nmol/L (P < 0.05), and plasma superoxide anion were 8.36 kcpm and 10.42 kcpm respectively (P < 0.05). It was suggested that Abemoschus manihot alcohol extraction could eliminate oxygen free radicals, alleviate renal tubular-interstitial diseases, improve renal function and reduce proteinuria.

Transcutaneous oxygen tension is a useful method with which to assess the functional status of skin blood flow. The reduced values observed in diabetic patients have been interpreted as a consequence of peripheral vascular disease. However, diabetic patients show lower transcutaneous oxygen tension values than control subjects with equivalent degrees of peripheral vascular disease, suggesting that additional factors are involved. Since the autonomic nervous system influences peripheral circulation, we studied the relationship between autonomic neuropathy and foot transcutaneous oxymetry in non-insulin-dependent diabetic (NIDDM) patients without peripheral vascular disease. The following age-matched patients were selected and evaluated: control subjects, C, (n = 20), NIDDM patients without autonomic neuropathy, D, (n = 16) and with autonomic neuropathy, DN, (n = 20). All diabetic patients showed lower transcutaneous oxygen tension values than control subjects, while no differences were observed between the diabetic patients with and without autonomic neuropathy. In addition the saturation index that increases in the presence of autonomic neuropathy does not correlate with foot TcPO2. In conclusion autonomic neuropathy does not influence foot TcPO2 and therefore it is unlikely that it contributes to development of foot lesions during induction of foot skin ischaemia.
