[State of microcirculation in patients with atherosclerotic-aetiology stage IV chronic arterial insufficiency of lower limbs].

The authors have studied the findings of the examination of and therapeutic outcomes in a total of one hundred and thirty-one patients diagnosed with atherosclerotic-aetiology stage IV chronic arterial insufficiency of the lower extremities. Of these, the dynamic analysis of the tissue blood flow on the background of haemodynamically efficient direct revascularization of the lower limbs was carried out in ninety-six patients. In a further 35 patients, a comprehensive instrumental examination of the blood flow on the background of chronic critical ischaemia was complemented by evaluating the morphological alterations in the skin of the foot of the affected extremity.

[The functional and sonographic parallels in chronic pancreatitis].

Ultrasonic histogramme was studied in 35 patients with chronic pancreatitis and 20 donors, taken in the area of the head and body of the pancreas, as were levels of immunoreactive trypsin--fasting and after standard food load,--and C-peptide in blood serum on an empty stomach. To increase informative value and specificity of ultrasonic and radioimmunologic investigations an index has been suggested, based on the findings from histogramme and radioimmunity analysis.
