Cereal and nut bars, nutritional quality and storage stability.

Six snack-type bars were manufactured, to contain oat and wheat germ and two different walnut levels, agglutinated with natural sweeteners and fats. Two bars also contained toasted amaranth with brown sugar cover and wheat extrudate, while two others, contained puffed instead of toasted amaranth. Water activity (Aw) and moisture were determined in the manufactured products. Quality and sensory evaluation and proximate analysis were carried out on the bars containing highest levels of walnuts (18%). The caloric contribution of the bars was computed by Atwater methods. The nutritional quality of the bars was determined by means of the Protein Efficiency Ratio (PER) and Net Protein Ratio (NPR), and the results were used to obtain relative PER and relative NPR. Samples of the latter bars were kept under accelerated storage for 15 days at 37 degrees C and analyzed every 5 days to determine their Aw, moisture, peroxide and sensory acceptability. The drying time for the cereal - and walnut - based bars was 45 min at 120 degrees C. All bars presented a good fiber supply and the CN1 bar, containing only oat, wheat germ and walnut, had the greatest protein content. In the sensory evaluation, the walnut level with the greatest preference was 18%. PER and NPR values of the bars did not differ significantly showing values approximately 86% that of the casein value. During storage, the moisture and Aw decreased in all the bars. Peroxides remained within the acceptable ranges; acceptability based on sensory evaluation remained best in the bar with toasted amaranth.(ABSTRACT TRUNCATED AT 250 WORDS)

[Usefulness of magnetic resonance imaging in the diagnosis of diaphragmatic rupture in 3 cases].

We report three male patients in whom the diagnosis of diaphragmatic rupture was raised. Conventional X ray examination showed an unilateal bulging of the diaphragmatic dome in two and the association of basal atelectasis in the third. Magnetic resonance imaging confirmed the diagnosis of diaphragmatic rupture in all. The diaphragmatic rupture was repaired surgically in two patients and the other was managed medically.

[Intraperitoneal cancer chemotherapy using an implantable reservoir in patients with peritonitis carcinomatosa].

Intraperitoneal cancer chemotherapy using an implantable reservoir has been recognized as an effective treatment. In this report, we evaluate treatment results in 20 cases undergoing this chemotherapy and the correlation between reservoir-use period and cumulative survival rates. Twenty patients with an average age of 59.3 years were all observed to have peritoneal dissemination during operations in the period of January 1987 through January 1991. Their primary diseases were 10 cases of gastric cancer, 8 cases of colorectal cancer, 1 case of appendiceal carcinoma, and 1 case of malignant tumor of retroperitoneum. Intraperitoneal reservoirs were implanted in surgically-made pockets in subcutaneous lower abdomen, and their catheters were inserted into Douglas cul de sac. Medications used were CDDP, MMC, and 5-FU. The average number of administration was about 6 or 7, but, the maximum number was 67 in one case. Contrast media or RI infused via reservoirs was recognized to diffuse widely within the peritoneal cavity. Eighteen of 20 cases (90%) obtained good conditions to undergo ambulant treatments. The longest survival records were 827 days in a gastric cancer group, 639 days in a colorectal cancer group, and 326 days in a malignant tumor of retroperitoneum group. Two cases having the former two survival records are still alive at this writing. One case with appendiceal carcinoma is PS 0 and now under out-patient treatment at 2 years and 6 months after operation. The 50% survival period, and 6-month, 1-year, and 2-year cumulative survival rates were 8.8 months, 60%, 40.5%, and 37%, respectively in the gastric cancer group; and 13.5 months, 75%, 63%, and 31.5%, respectively, in the colorectal cancer group. On the contrary, 50% using period, and 6-month, 1-year, and 2-year cumulative using rates were 5.3 months, 40%, 10%, and 10%, respectively, in the gastric cancer group; and 7.9 months, 58%, 0%, and 0%, respectively, in the colorectal cancer group. Evaluation of the correlation between the reservoir use periods and cumulative survival rates has led to the conclusion that cumulative survival rates are extended significantly p = 0.0011 in each cancer group with more than 6 months treatment period compared to within each cancer group with less than 6 months treatment. 1) Intraperitoneal cancer chemotherapy using an implantable reservoir enables patients to receive treatment at outpatient clinics. 2) The continuous treatment for more than 6 months suggests the possibility for longer survival.

[Sensory evaluation and acceptability study, at the consumer level, of bread supplemented with sweet lupine flour].

The purpose of this study was to determine the effect of incorporating sweet lupine flour (SLF) to bread, upon the organoleptic characteristics and acceptability of the product. The substitution levels were 3, 6, 9 and 12%. The sensory evaluation test was done by 25 trained judges using the hedonic scaling method (9 to 1 scoring). Internal and external characteristics of appearance, color, aroma, texture, bitterness and flavor, as well as general acceptability, were measured. Sensory evaluation results of the external characteristics were significant at the 9 and 12% SLF levels for color (p less than 0.05) while the other parameters did not show significant differences. In regard to the internal characteristics, a significant difference for color was found at the 3% level of SLF (p less than 0.05); and at 6, 9 and 12% SLF levels, for appearance (p less than 0.05). The general acceptability was good at all the levels tested, with no significant differences among them. An acceptability study at the consumer level for 9% lupine flour bread was carried out in a group of 90 girls, aged 10-12 years, during a 10-day period. The results showed a very good acceptability of the product (p less than 0.01). The results of this study indicate that the incorporation of 6% SLF to the bread, did not affect adversely its sensory properties. Moreover, the acceptability of bread containing up to 12% SLF was excellent.
