By use of histomorphometry and photon and physical, calcium homeostasis, bone morphology, bone mass and bone growth were studied in freely fed control, streptozotocin-induced diabetic, long-term and short-term insulin treated diabetic rats 14 weeks after the induction of diabetes. We conclude that untreated chronic streptozotocin-induced diabetic rat could result in abnormal bone and mineral metabolism, which is characterized by hypercalciuria, hyperphosphaturia and hyperphosphatemia, significant bone loss and growth arrest. The extent of bone loss correlated with the duration of the disease process. The anatomical basis of bone mass reduction is the diminution of osteoblasts activity which results in reduction of bone formation and insufficient bone calcification and relative increment of osteoclasts activity. Thus, bone resorption overweight bone formation leading to a negative balance of bone remodeling. The effect of PTH and CT on bone changes in diabetic rats can't be affirmed in our experiments. It is probable that metabolic disorder and/or insulin deficiency has a direct effect on bone changes. Insulin therapy started earlier in the course can prevent and somewhat later can completely normalize the altered skeletal morphology of diabetic rats. Whether this result is due to direct effect of insulin on skeletal tissue or through the correction of metabolic disorder remains to be resolved.

Basal serum growth hormone and response of GH to GRF in 10 patients with noninsulin-dependent diabetes and in 10 control subjects were studied. The basal GH level in NIDDM was higher than that in control subjects. There was a significant difference. After an intravenous bolus of hGRF 1-29 NH2 with the dose of 1 microgram/kg body weight, GH (Peak level-basal level) decreased in NIDDM patients in comparing with control group (P < 0.05). These findings may suggest that the pituitary GH reserve is reduced in patients with NIDDM. There exists some defect in central GH control in diabetics with enhanced somatostatin secretion and abnormal sensitivity of the GH secretion cells to a variety of regulatory factors including GRF, glucose, amino-acids, free fat acid.

Function of gastric motility was studied in thirty one diabetes mellitus patients by testing gastric emptying time (GET). The test was performed by giving patients food labelled with 99mTc. The results showed that GET in patients with diabetes mellitus was significantly delayed as compared with that in the controls (P less than 0.001). 15 among the 31 diabetic patients had delayed GET, accounting for 48.4%. There was no difference in age, duration of the disease, treatment regimen and microvascular complications between patients with delayed GET and those with normal GET. The only difference was the obviously increased incidence of autonomic nerve dysfunction in the former group of patients (P less than 0.05). We concluded that the incidence of delayed gastric emptying time was higher in diabetic patients with autonomic neuropathy.

Lipid peroxide (LPO) values in blood plasma, along with the glutathione peroxidase (GSH-PX) activity in whole blood and superoxide dismutase (SOD) activity in erythrocytes were determined in 50 patients with non-insulin-dependent diabetes mellitus (NIDDM) and in 33 control subjects. The mean LPO value, SOD activity, LPO/GSH-PX and LPO/SOD ratios in the diabetic patients were significantly higher than those in the control subjects. The increases of LPO value, LPO/GSH-PX and LPO/SOD ratios were more pronounced in diabetics with microangiopathy than in those without microangiopathy. Our results suggest that free radicals may be implicated in the pathogenesis of diabetic microangiopathy.

The number of estrogen receptors (ER) in human peripheral leucocytes in 12 women with menopausal type II diabetes was measured with radio-ligand binding method. The results were compared with those of 12 menopausal women without diabetes and 12 normal women of childbearing age. It was found that the number of ER in the patients was significantly decreased. Our data indicate that decrease of ER level in leukocytes may be related to the pathogenesis of type II diabetes in menopausal period.

Surface electrogastrograms were recorded in 95 patients. There were 6 groups of patients: chronic superficial gastritis (20), chronic atrophic gastritis (20), duodenal ulcer (20), gastric ulcer (17), gastric cancer (8), and diabetes mellitus (10). Electrogastrographic examination was continuously carried out for 60 minutes both in fasting and postprandial state. (1) During the fasting state, in 72% of the cases, there was a 50% to 100% change in the mean of the amplitude among six 10-minute periods of recording. (2) In 23 cases (25%), there was no amplitude increase in the postprandial electrogastrogram. Feeding caused an increase in amplitude by 30-240 microV over the prefeeding state in 70 cases (75%). (3) The distribution of amplitude in various groups of disease overlapped each other. The difference in amplitude or frequency would not be used as a diagnostic parameter of gastric diseases. (4) Tachygastria of 5-7.3 cycles per minute was observed in 15 of the 95 patients. The longest episode was a wave with 7.3 cycles per minute lasting for 20 minutes. It is difficult to evaluate the clinical significance of the observed tachygastria.

Twenty-four hour urinary albumin (Alb) beta 2 microglobulin (beta 2m) and Tamm-Horsfall protein (THP) were measured by radioimmunoassay in 69 diabetics and 23 normal controls. The excretion of urinary Alb, beta 2m and THP in the patients with diabetic nephropathy was found to be different from that of normal controls. The abnormality of excretion of Alb, beta 2m and THP is particularly evident in the patients with clinical diabetic nephropathy. These results indicate that the renal lesions of diabetes mellitus exist not only in the glomeruli but also in the proximal and/or distal tubules. There was a significantly positive correlation between THP excretion and creatinine clearance (less than 127 ml/min/1.73m2). The findings suggest that the excretion of urinary THP is a valuable index for evaluating the damages of nephrons. It is believed that determination of urinary Alb, beta 2m and THP in diabetics is beneficial to early detection of the sites and degree of the renal lesions.

The hypercoagulable state in patients with diabetes mellitus, glomerular diseases and pregnancy induced hypertension was studied by using new methods. The research items included platelet function, coagulation, anti-coagulation system, fibrinolysis and TEG examination. The results showed that there was a hypercoagulable state in patients with diabetes mellitus, pregnancy induced hypertension and glomerular diseases, especially in those with uremia and nephrotic syndrome.

The effect of EPA enriched marine oil on platelet function in 12 cases of hypertension, 15 cases of diabetes and 20 cases of coronary heart disease is reported. The result of our study showed that there was platelet hyperfunction of various degrees in patients with those three kinds of diseases. The murine oil had an effect of inhibition, which were manifested by the prolongation on bleeding time, and decreased on platelet adhesion and aggregation. TxB2 in plasma was reduced, while 6-keto-PGF increased. There was no influence of EPA enriched fish oil on blood sugar and liver or kidney function. The authors concluded that platelet hyperfunction is an important element in the development of cardio vascular and cerebro vascular complications and increases the mortality rates in these diseases. Treatment with such a drug has beneficial effect with clinical improvement.

Although oral glucose tolerance test (OGTT) has been the key examination in early diagnosis of diabetes mellitus, but it still has some problems. It may be affected by some physiological or pathological changes and also requires frequent blood sampling. We investigated the usefulness of measuring the level of glycated hemoglobin (GHb) or HbA1 and HbA1c in screening or early diagnosis of diabetes mellitus. OGTT was performed and fasting levels of HbA1 and HbA1c were measured in 168 subjects. According to the diagnostic criteria of WHO for 75g OGTT, 31 subjects were classified as normal, 35 as having impaired glucose tolerance test (IGT) and 102 as diabetics. The method used for determination of HbA1 and HbA1c was high pressure liquid chromatography (HPLC). The total discovery rate for GHb in diabetic patients was 87%. In patients with fasting level of plasma glucose (FPG) greater than or equal to 8 mmol/L the discovery rate was 100%, while in those with level of FPG less than or equal to 7.94 mmol/L the rate was 80%. Thus, GHb is very useful in screening and early diagnosis of NIDDM (type II), especially diabetes mellitus of the elderly.
