Electronic microscopic evaluation of the Beta insular cells in type 2 diabetes.

In this work it has been done an electronic microscopic evaluation of the intra-cytoplasmic organelle devices of the pancreatic beta insular cells in the type 2 diabetes mellitus (insulin independent). The motivation of this study is the lesions noticed within another study, photonic microscopic, reason why we have considered it important to show up as well the interest modifications of the constitutive organelles of the beta insular cells.

Microscopic assays regarding the renal damage following a post-combustional shock.

Over a period of three years (2000-2003) 39 autopsies were performed on patients with burns. Among them a number of 11 men and 28 women were aged between 28-92 years, the total burnt body surface was of 20% to 95%. Of all the cases nine patients died during the first 24-36 hours since the accident happened, presenting a burnt surface of more than 70%. In these cases, the renal lesions were minor but critical, presenting symptoms of acute renal failure (ARF). Subsequently, a number of 25 patients died within 1-4 weeks since the accident. Renal lesions were complex with tubular necrosis, lymphocyte infiltration and micro-abscesses. The burnt body surface of these patients was of 41-85%. In three cases, when death occurred within four weeks of hospitalization, the patients presented damages to other organs as well (multiple organs failure--MOF). The kidneys displayed tubular necrosis, fibrous micro-thrombi and infarct areas. In two cases coagulation intravascular dissemination occurred in patients with burnt body surface of 45-70% and aged of 42 and 60 years. Micro-thrombi and infarct areas dominated the renal lesions.

[Eclamptic amaurosis].

A 16 years old pregnant women with no pathological antecedents, with normal blood pressure and biological parameters and without edema, presents an eclamptic crisis before delivery and another one after delivery, with total amaurosis. The eye fundus examination did not show pathological elements. The brain computerized tomography revealed the hypodense areas with ischemia aspects, about 5/2 cm in left occipital lobe and 3/1 cm în right loccipital lobe, also left parieto-occipital hypoperfused areas. In development of occipital ischemia beside placenta ischemia, genetic and immunologic factors there is also an inflamatory element determined by cytokines released from placenta.
