Micro Vascular Changes in the Placenta of Bangladeshi Overt Diabetic Mothers and Hypertensive Diabetic Mothers.

It is a significant medical problem when Pregnancy is complicated by diabetes and/or hypertension which affect not only affecting maternal health, but also jeopardizing fetal normalcy? The placenta being the bridge between maternal fetal activities, this structure is considered as a window through which understanding of maternal dysfunctions as well as of their impacts on fetal wellbeing can be obtained. And as it is an almost all-vessel organ, its functional status depends primarily on the structural status of its vessels. To observe vascular changes in the placenta, a study was carried out on 44 placentas.19 from overt diabetic mothers having no hypertension and 5 from hypertensive diabetic mothers, and 20 from control group having no hypertension or diabetes. These were collected just after delivery though caesarian section. Microscopic findings of the study were that there was a trend of greater intimal thickness at the second branching site in the overt diabetes group than the control group. But at the first and last branching site this tendency was reversed. But none of these tendencies reached statistical significance. In case of the hypertensive diabetes group, there was a tendency of greater intimal thickness at the first, second and last branching sites as compared to the control group. Hypertensive diabetes group also showed significantly greater intimal thickness at first and last branching sites than the overt diabetes group.

Effect of fenugreek seeds on the fasting blood glucose level in the streptozotocin induced diabetic rats.

In this experiment defatted Trigonella foenumgraecum (fenugreek seeds/methi seeds) has used as the antidiabetogenic herbal medicine. The experiment was carried out in Bangabandhu Sheikh Mujib Medical University and BIRDEM from 1996 to 1998 on a total of 58 Long Evans rats of either sex. They were 50-60 days young rats with average body weight 72-174 gm. Among the total, 10 rats were treated with only vehicle called as non-diabetic control rats, 48 rats were treated with Streptozotocin (STZ) at a dose of 90 mg in 1 ml of citrate buffer solution per kg body weight, among which 20 were diabetics. Ten (1 died, 1 escaped) diabetic rats were again treated with fenugreek called as Fenugreek-treated diabetic rats and the rest 10 diabetic rats were called as diabetic control rats. The change in the mean fasting blood glucose (FBG) level in different groups of rat from day 5 from streptozotocin injection were higher in diabetic control group and in fenugreek-treated diabetic group than in non diabetic control group. The FBG level on day 13 the mean in non-diabetic control group was 5.21 mmol/L. In diabetic control group and in fenugreek-treated diabetic group the mean FBG level were 24.33 mmol/L and 9.89 mmol/L respectively. So, from this experiment it may be concluded that fenugreek decreases the FBG level considerably by improving diabetes mellitus.
