Laparoscopy treatment of liver abscess secondary to an unusual foreign body (rosemary twig).

A hepatic abscess caused by a swallowed foreign body is a rare and challenging diagnosis. Most patients have nonspecific symptoms, and more than 90% of patients do not remember having swallowed it, which occurred accidentally. In this setting, fish bones, chicken bones, and toothpicks are the most found foreign bodies.

Damage control surgery: are we losing control over indications?

Objective: to analyze the surgeons' subjective indications for damage control surgery, correlating with objective data about the patients' physiological state at the time the surgery was chosen.

Methods: we carried out a prospective study between January 2016 and February 2017, with 46 trauma victims who were submitted to damage control surgery. After each surgery, we applied a questionnaire to the attending surgeon, addressing the motivations for choosing the procedure.

Infraspinatus Cross-Sectional Area and Shoulder Range of Motion Change Following Live-Game Baseball Pitching.

Context: Following a baseball pitching bout, changes can occur to glenohumeral range of motion that could be linked to injury. These effects are in part due to the posterior shoulder's eccentric muscle activity, which can disrupt muscle contractile elements and lead to changes in muscle cross-sectional area (CSA), as measured by ultrasound.

Objective: To assess changes in muscle CSA, and range of motion immediately before and after pitching, and days 1 to 5 following pitching.

Scapular bracing and alteration of posture and muscle activity in overhead athletes with poor posture.

Context: Overhead athletes commonly have poor posture. Commercial braces are used to improve posture and function, but few researchers have examined the effects of shoulder or scapular bracing on posture and scapular muscle activity.

Objective: To examine whether a scapular stabilization brace acutely alters posture and scapular muscle activity in healthy overhead athletes with forward-head, rounded-shoulder posture (FHRSP).

Humeral retrotorsion in collegiate baseball pitchers with throwing-related upper extremity injury history.

Background: Collegiate baseball pitchers, as well as position players, exhibit increased humeral retrotorsion compared with individuals with no history of overhead sport participation. Whether the humeral retrotorsion plays a role in the development of throwing-related injuries that are prevalent in collegiate baseball pitchers is unknown.

Hypotheses: Humeral retrotorsion will be significantly different in collegiate pitchers with throwing-related shoulder or elbow injury history compared with pitchers with no injury history.

Influence of humeral torsion on interpretation of posterior shoulder tightness measures in overhead athletes.

Objective: To measure the influence of humeral torsion on interpretation of clinical indicators of posterior shoulder tightness in overhead athletes.

Design: Cross-sectional control group comparison.

Setting: A university-based sports medicine research laboratory.

The involvement of polymorphonuclear leukocytes in the pathogenesis of bronchopneumonia in calves. VII. Granulocyte activation by arachidonic acid.

Arachidonic acid-induced granulocyte activation was studied in calves. Both in healthy and in bronchopneumonic animals, neutrophil stimulation with 67 microM arachidonic acid caused a rise in granulocyte exocytosis. This event, however, was much more intense in granulocytes from diseased calves.

The influence of endotracheally administered bleomycin on hydroxyproline content and collagenase and elastase activity in rat lungs.

The effect of endotracheal administration of bleomycin (10 mg x kg-1) on hydroxyproline content, and on collagenase and elastase activities in rat lungs was investigated. A significant increase in lung tissue hydroxyproline content on 7th day after bleomycin administration was observed. Similar rise in this amino acid level in bronchoalveolar lavage was observed, however, on 14th day after the drug administration.

The influence of endotracheal bleomycin administration on phospholipid composition of rat lung surfactant.

The influence of intratracheal bleomycin instillation (10 mg x kg-1) on lung surfactant phospholipids in rats after 7 and 14 days from drug administration was evaluated. It was stated that bleomycin causes a great fall in phosphatidylcholine, disaturated phosphatidylcholine and phosphatidylglycerol content, both in extra- and intracellular pool of surfactant. The data thus presented evidenced that intratracheal bleomycin administration caused a profound changes in the lipid composition of rat lung surfactant.

Fatty acid composition of near-term and beyond-term pig placenta.

The fatty acid composition of four major phospholipid classes of near-term and beyond-term pig placenta was investigated. In beyond-term pig placentas much lower levels of linoleic, dihomo-gamma-linolenic and arachidonic acids were observed, as compared to near-term organs. It is suggested that beyond-term pregnancy in the pig may be caused by a deficiency of prostaglandin precursors in the placenta.

[The influence of intratracheal bleomycin instillation on peroxidative processes in rat lung tissue].

The influence of intratracheally instilled bleomycin (10 mg x kg-1) on antioxidant enzyme activity as well as on lipid peroxidation product levels after 7 and 14 days from drug administration in rat lungs was investigated. The 200-400% increase in superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase and glucose-6-phosphate dehydrogenase activities were observed, as compared to control group. The levels of malondialdehyde, conjugated dienes and lipid hydroperoxides in lung tissue of bleomycin-treated rats were also higher than those in control group.

[Lipids of the liver and aorta of rabbits fed with cholesterol before and after surgical exclusion of the terminal segment of the ileum].

The experiments were carried out on 15 rabbits od common breed in 3 groups, K--control, 1--unoperated and 2--operated. The weight of the animals before operation oscillated from 3.8-4 kg.

[Effect of surgical exclusion of the terminal segment of the jejunum on plasma lipid level in rabbits after administration of a cholesterol-fat diet].

The examinations have been performed on 10 native albino rabbits in two experimental groups. Before the experiment the content of a total, free and esterified cholesterol, triglycerides, free fatty acids lipoproteids was determined in heparinised blood plasma. The obtained values served as a control.

The effect of prostaglandins E1, E2, F1 alpha and F2 alpha on pig erythrocytes during haemolysis induced with aspirin and hypotonic NaCl solution.

The effect of prostaglandins PGE1, PGE2, PGF1 alpha and PGF2 alpha was investigated on the haemolysis of pig erythrocytes induced with aspirin and hypotonic (0.119 M) NaCl solution. An inhibiting effect was observed of low concentrations (2 X 10(-5) M, 2 X 10(-4) M and 2 X 10(-3) M) of aspirin on haemolysis induced with hypotonic NaCl solution, while in a concentration of 2 X 10(-2) M aspirin itself caused haemolysis which amounted to 93% of the haemolysis induced with 0.

Occurrence and characteristics of sclerotic lesions in uterine arteries of sterile and multiparous pigs.

Sows and gilts of the Great White Polish (GWP) breed were classified into groups of 10 each: gilts 8 mo of age (A), sows over 1 yr old with an average litter size of five (BI) and eleven (BII), 2- to 3-yr-old sows with an average litter size of five (CI) and nine (CII), 4- to 6-yr-old sows with an average litter size of six (DI) and nine (DII). Gilts of group A were necropsied on d 10 of the estrous cycle while sows were necropsied 120 to 360 d postpartum. A blood sample obtained by vena cava puncture immediately before exsanguination was quantitated for total cholesterol, free cholesterol, cholesterol ester, total lipid, triglyceride, high and low density lipoprotein and chylomicrons.

[Lipids of the plasma, aortic wall and egg yolk of egg-laying hens after short-term feeding with atherogenic diet].

In laying hens of the Cornish breed about 1,8 kg of body weight, which, beside being fed abundantly for 4 days, were given 1 g of cholesterol and 1 g of pork fat in a piece directly into the crop, attempts were made to determine the level of fat compounds in blood plasma, in the wall of the abdominal aorta, and egg cell yolk. The control group was kept in similar conditions, receiving a bare piece of food. Blood was taken on empty stomach from the heart on heparin.

[Effect of partial ileal bypass on the liver lipid level in dogs on an atherogenic diet].

An attempt was undertaken to find out to what extent a partial ileal bypass in healthy dogs fed for 6 and 12 months on overloaded atherogenic diet with an addition of metizol influences the level of lipids and the development of atherosclerosis of the aorta. For the investigations 16 mongrels, both sexes, from 2 to 5 years old were used. an unoperated, control group consisted of 6 dogs, which were fed on the atherogenic diet for 12 months.

[Effect of atherogenic diet on the liver lipid level and development of aortic sclerosis in dogs].

Metabolic efficiency of the liver of 16 dogs, mixed breed, sexually mature, of both sexes was studied in a lasting experiment. The animals were kept in cages without a run, divided into 3 groups - k, A6 and A12. They were fed an atherogenic diet for 6 and 12 months.
