background controlling parenchymal hemorrhage especially in liver parenchyma, despite the progress in surgical science, is still one of the challenges that surgeons face when trying to save patients’ lives. researchers in the field are challenging to introduce a more effective method. objectives the current study aimed to determine the haemostatic effect of alum [kal (so4)2] and compare it with...

The study described herein was undertaken to determine the role of proteins, in general, and collagen, in particular, in the observed absorption and speed of ultrasound in biological tissues. It had earlier been observed that ultrasonic absorption in tissues occurs at the macromolecular level, •'z though an additional contribution to attenuation arises from tissue structural features. a Each of...

As a first step in determining the efficacy of using computers to assist in diagnosis of medical images, an investigation has been conducted which utilizes the patterns, or textures, in the images. To be of value, any computer scheme must be able to recognize and differentiate the various patterns. An obvious example of this in mammography is the recognition of tumorous tissue and non-malignant...

from the right side of the rat were used to determine the radioactivity contained within the mammary teat, fat pad, and vascular areas, while those from the left side were separated into parenchymal cell and fat cell fractions. The intracellular lipid of the parenchymal cells was extracted and quantitated. Although the pattern of carcinogen uptake and clearance by the parenchymal cell intracell...

The aim of this study was to evaluate breast parenchymal activity on scintimammography with bone-seeking agents and 99mTc-MIBI. Scintimammography was performed with bone-seeking agents in 61 patients and with 99mTc-MIBI in 33 patients. Activity in the breast parenchyma contralateral to the suspected lesion was visually assessed by two independent observers. Increased breast parenchymal activity...

The effect of dietary and hormonal variations on the specific activities of hexokinase isoenzymes, N-acetylglucosamine kinase and pyruvate kinase isoenzymes in parenchymal and non-parenchymal liver cells was studied. Hexokinase D was markedly decreased in hepatocytes from animals fasted or fed on the carbohydrate-free diet as well as from diabetic rats, attaining a constant low level of about 1...
