background central venous catheterization is done frequently in cardiac surgery and intensive care settings. faulty positioning of the catheter can cause many complications. objectives the aim of our study was to study the average depth of insertion and formulate a general guideline through the right internal jugular vein (ijv). patients and methods the right ijv was cannulated over a period of...

in this investigation, 25 adult new zealand white rabbits randomly selected from both sexes and studied.coloured latex injection and corrosion cast methods were applied on the materials. this study was carried out to disclose the distribution of the cardiac veins of the new zealand white rabbits. the veins that drain the heart were found to be the great cardiac vein, the middle cardiac vein, th...

1. In 125 cases of perirenal fat samples derived from human necropsies (from 1 month to 86 years), the occurrence of the brown adipose tissue was examined. Brown fat cells were contained in 72% (90: 125) of the cases. 2. In the infants, all samples contained maximal amounts of brown fat cells: the perirenal fat was composed almost exclusively of brown fat cells: in children and teenagers they b...

introduction: to compare endovenous laser ablation (evla) and radiofrequency ablation (rfa) in different legs in the same individual in patients with venous insufficiency. methods: sixty patients with bilateral saphenous vein insufficiency were included. evla or rfa was applied to one of the patient’s legs and rfa or evla to the other leg. results: evla and rfa complications were hyperemia at 2...

The volatile compounds (VCs) in headspace of adipose tissues (perirenal, tail, caul) were extracted by solid-phase microextraction (SPME) fiber coated with carboxen/ polydimethylsiloxane (CAR/PDMS) or divinylbenzene/ polydimethylsloxane (DVB/CAR/PDMS). In extraction CAR/PDMS coating compared to DVB/CAR/PDMS, more VCs obtained perirenal (53 versus 41), tail (51 vs 47) and caul (35 33) fats. Incr...

Idiopathic thrombocytopenic purpura (ITP) is an immune thrombocytopenia with a usually benign clinical course. Bleedings are mostly of the mucocutaneous type with mild symptoms. Massive bleedings requiring transfusion are rarely seen, unless the number of platelets decreases to extremely low levels. In this case, bilateral perirenal hematoma and bilateral distal ureteral stones were detected on...

Polybrominated biphenyl (PBB), a fire retardant, was accidentally substituted for an animal feed supplement in Michigan 10 years ago. This led to widespread livestock contamination and ultimately to contamination of virtually every human residing in the State at that time. In order to evaluate the extent of PBB persistence and distribution in human tissues 10 years after this accidental poisoni...

Previous morphological studies revealed that the adipose tissue is innervated by adrenergic nerve fibers. Furthermore, physiological studies showed that the metabolism of adipose tissue is controlled by the adrenergic component of the nervous system. However, nothing is known on the sources of innervation of different fat tissue depots. Therefore, we decided to study the distribution of ganglio...

In vitro measurements of metabolism were made in subcutaneous and perirenal adipose tissue (AT) and liver from prenatally androgenized ewe lambs (TE), control ewe lambs (CE), and control wether lambs (CW). In adipose tissue slices, release of glycerol or fatty acids into the medium was not different among treatments, but glycerol release was greater (P < .01) from subcutaneous AT than from peri...

Introduction: Urinary stone disease is an important morbidity. Metabolic factors such as obesity and diabetes mellitus have been associated with stone disease. Because obesity and increased body mass index, which are characterized by thickening of subcutaneous and visceral tissue, are associated with kidney stones, we investigated subcutaneous and perirenal tissue thickness and stone size in pa...
