Effects of green and black tea on hepatic xenobiotic metabolizing systems in the male F344 rat.

1. The induction of phase I and II enzymes in the liver of the male F344 rat drinking 2% (w/v) solutions of green or black tea for 6 weeks was investigated. Also studied were glutathione (GSH) and cyst(e)ine in blood, liver and kidney, as well as serum cholesterol, HDL cholesterol, triglycerides, and total and free testosterone. 2. The total carbon monoxide-discernible liver P450, b5 and NADPH-cytochrome c(P450) reductase activities were similar in all groups. 3. There were significant increases in liver of rat drinking green or black tea of P4501A1, 1A2 and 2B1 activities, but no change in P4502E1 and 3A4 activities. Of the phase II enzymes, UDP-glucuronyltransferase was increased, but glutathione S-transferase was not. 4. Serum GSH was higher in the group administered black tea, but GSH and cyst(e)ine in other groups was at control levels. Serum cholesterol was lower in rat given black compared with green tea. Triglycerides had a declining trend after green and black tea exposure compared with water controls. Free and total testosterone were not affected. 5. Thus, beverages widely used by man altered host biochemistry as regards specific phase I and II enzymes in liver of rat and specific serum parameters.

Clinical investigations of tolerance to materials and acrylic cement in patients with hip prostheses.

In forty-two patients with prostheses of the hip followed up after an interval, the authors carried out skin allergy tests against the metals of which the prostheses were composed, and against methacrylate. They found that the tests gave positive results in about 25 per cent of cases. They also investigated whether this finding showed any relationship with loosening or movement of the prostheses. There was no statistically significant relationship, either with loosening or with the passage of time since the operation.

[Considerations about surgical treatment of complex fractures of malleoli (author's transl)].

According to the results established after careful observation of the series of cases (50 at all) examined, the malleolus fractures are submitted to analysis by the authors of the text. The outcome they achieve is the recovery may be attained, with better probabilities, only by the operation. The recovery is meant as complete both in the bony parts and in the ligaments' ones.

[Lumbago and arthrosis of posterior vertebral articulations (author's transl)].

Such Authors value the importance of the arthrosis of the posterior vertebral articulations in the genesis of back pain with or without sciatica. A particular attention must be put on the correct differential diagnosis of the various back pains. They furthermore present their casuistry. The made results through endoarticular injection of steroid and local anesthetic are good. 78% of the subjects has gone back to work; even though this treatment must be considered only one mean to permit a better physical and natural activity.

[Diagnostic picture of spinal tumors].

A correct classification both primary and secondary of the spinal tumour is given dealing with a present argument. The clinical aspect and The radiology of the different kinds of tumour are specified. Moreover they are classified according to their anatomo-pathological aspect. A complete analysis of the argument is the result of this work.

[Pre- and post-operative evaluation of biologic parameters in patients with scoliosis (author's transl)].

The authors had studied biological parameters of respiratory and muscle function in patients effected by scoliosis before and after surgical treatment according to Harrington method, in order to evaluate a correlation with the anatomical deviations. The study has been led by spirometric and electromyographic tests, which have show a real correspondence between the anatomical situation and the considered parameters before and after surgical treatment, and emphasizing an improvement of respiratory and muscle function.

[Reasons for treatment failures in carpal scaphoid fractures].

Are taken into examination the principal causes of mechanical, biological, anatomical order, of incorrect treatment to whom to give the evolution in pseudoarthrosis of scaphoid fractures and of unsuccess for their bloody treatment. Cases of insuccesses is presented for whom is tried to give to each one of them an etiopathogenetical explanation and the most recent techniques adopted are shown.
