Ruptured Ovarian Cystic Teratoma: A Rare Diagnosis, Easily to Be Confused with Peritoneal Carcinomatosis.

Although ovarian cystic teratoma is the most common ovarian tumor, complications are quite rare. However, it is important to be recognized by the radiologist in order to avoid inaccurately diagnosing them as malignant lesions. This case report describes a 61-year-old postmenopausal woman, who presented to the emergency room with abdominal pain following a minor blunt abdominal trauma.

Evaluation of the polarographic technique for assay of the viability of freeze-dried BCG vaccine: II. Viability of the vaccine assessed by polarography, Warburg respirometry and colony counting.

A comparative study of the viability of 34 lots of freeze-dried BCG vaccine has been carried out using an oxygen electrode polarographic technique, Warburg respirometry and colony counting. There were no statistical differences between the results obtained with the polarographic and Warburg techniques. Both methods gave reliable and similar results and showed a positive correlation (r = 0.

Evaluation of the polarographic technique for assay of the viability of freeze-dried BCG vaccine: I. The polarographic technique.

In this paper, a new assay based on oxygen uptake assessed by polarography was evaluated with the aim of establishing the viability of freeze-dried BCG vaccine. An oxygen electrode possessing a temperature sensor was designed for this purpose. The polarographic method used had several advantages, particularly its rapidity and use of small amounts of biological material.

Blood glucose partition and levels of glycolytic enzymes in erythrocytes and somatic tissues of penguins.

1. A comparative study was carried out on blood glucose partition and glucose metabolism of penguin erythrocytes and somatic tissues. Pygoscelidae penguins (Pygoscelis antarctica and P.

Metabolic activity of the Sticker's lymphosarcoma.

Some parameters (glycolysis, respiration, levels of glycolytic enzymes) of the lymphoid cells from the Sticker's lymphosarcoma were established in order to better define the biochemical behavior of the venereal tumor of the dog. For comparative purposes lymphocytes from peripheral blood of normal and tumor-bearing dogs were also studied. Lactic acid produced by the tumor cells during aerobic glycolysis is liberated in the reaction medium.

A technique for the determination of the available oxygen in living carp (Cyprinus carpio) muscle.

A polarographic method for the measurement of the available oxygen in the muscle of living carp by the use of a platinum microelectrode is proposed. The oxygen and the reference electrodes were assembled in a single insertion piece which was implanted in the muscle of a living carp maintained in a special experimental chamber. Curves for normal oxygen levels corresponding to air-saturated water, as well as to a carbogene-saturated water, were obtained.

Comparative levels between enzymes of the glycolytic pathway from erythrocytes and somatic tissues of the chicken Gallus gallus domesticus.

A comparative study on the glycolytic enzymes from chicken erythrocytes and somatic tissues has been carried out, the results being shown as active units per mg protein in supernatants of 1085, 12,100 and 106,000 g fractionated centrifugation. The profiles of the glycolytic enzymes have been analyzed in terms of their activity relative to hexokinase and as the ratios between pairs of enzymes bearing a product-substrate relationship. Chicken erythrocyte displays a very peculiar profile of glycolytic enzymes.

Studies on the structure of aldolase A from chicken muscle.

S-Carboxymethylated chicken muscle aldolase was treated with cyanogen bromide to cleave the 4 methionyl bonds per subunit. Five homogeneous fractions were obtained designated fragments I-V. Fragment I was derived from the N-terminus and fragment II from the C-terminus of the enzyme.

Comparative levels of muscle glycolytic enzymes in mammals, fish, echinoderm and molluscs.

1. Levels of glycolytic enzymes were determined in terms of units of enzyme/mg protein in rat striated muscle, carp lateral muscle, holothuria longitudinal muscle of the body wall, and a snail foot muscle. 2.

General effects of beryllium sulfate on isolated rat heart muscle mitochondrial fraction.

The effects caused by Be2+ on the properties of isolated rat heart muscle mitochondria were investigated. It has been shown that Be2+ enhances oxygen uptake by the mitochondrial fraction in the presence of oxidizable substrates. This is due to the uncoupling effect caused by Be2+ on the mitochondria, which also undergoes a swelling effect by this divalent ion that can be accounted by the retention of Be2+ by the mitochondria.

Purification and properties of rabbit heart muscle aldolase.

Fructose diphosphate aldolase (D-fructose-1,6-biphosphate D-glyceraldehyde-3-phosphate lyase, EC 4.1.2.

The effect of beta-bromopyruvic acid on fructose-1, 6-diphosphate aldolase from rabbit muscle.

Rabbit muscle aldolase (RMA) is 96 per cent inhibited in the presence of beta-bromopyruvic acid (BPA) in a molar ratio of 1/250, during 60 minutes incubation. The chemical reaction of higher significance in this phenomenon is the alkylation of -SHgroups of both apparent and buried types, with formation of S-pyruvil-cystein. The previous treatment of the enzyme with FDP protects aldolase, decreasing the rate of inhinition by BPA to about 56 per cent.
