Comparison of lipid changes in chicken frankfurters made by soybean and canola oils during storage

Two batches of frankfurters containing about 55% chicken meat with two different oils [including canola and soybean] were manufactured. Batch 1 included canola oil and Batch 2 included soybean oil in the products. Various analyses were performed to detect the lipid changes of both batches during storage. Fatty acid composition analysis using gas chromatography showed little change in the fatty acids of either batch over time. From a nutritional viewpoint, Batch 1 was more acceptable over time than Batch 2. Chemical analysis included oxidation reactions, such as peroxide and TBA [Thiobarbituric acid] value and free fatty acid analysis. Each chemical experiment had different trends at each time, but both batches had values lower than the maximum levels at all times. With regard to microbial analysis, psychrotrophic bacteria in both batches showed a decreasing order until day 30, and then growth increased. In Batch 1, a significant difference was observed only on day 1, but the differences were more significant in Batch 2, and there were significant differences on days 15, 30 and 45. Also, Lactobacillus counts were not significant after the cooking process until the end of storage [growth was not detectable after the cooking process]. At the end of storage, we concluded that Batch 1 had a higher quality and storage stability than Batch 2 and canola oil could be a good substitution for soybean oil in meat products. The data were analyzed with GLM [repeated measures]. Differences were reported as significant at P<0.05. Also, the statistical software was SPSS ver. 11.5

[Effect of palm seed alcoholic extract on the blood glucose and lipids concentration in male diabetic rats]

Diabetes mellitus is the most common endocrine disorder which can lead to hyperglycemia and hyperlipidemia. The incidence of diabetes mellitus is expected to increase in human population in the future. The present study deals with the effect of palm seed extract on the blood glucose and lipids concentration in male diabetic rats. In this experimental study, 40 adult male Wistar rats, each weighing about 240-250 gr, were divided into 4 groups: control and diabetic [received nothing] treated control and treated diabetic groups [received palm seed extract]. In order to induce diabetes, stereptozotcin was injected intraperiotoneally [60mg/kg]. The treated groups received [0.5mg/kg] palm seed extract intraperitoneally every day. 14 days latter, blood samples were obtained from all groups and serum levels of glucose and lipids were measured. Concentrations of glucose, cholesterol, LDL, increased significantly in diabetic group when compared with those of control group [p < 0.05], while these values in the treated diabetic group showed a significant decrease compared with those of untreated diabetic group. In addition, the serum level of HDL in diabetic and treated diabetic groups was considerably less than those of control and treated control groups [p < 0.05]. But the concentration of triglyceride didn't show any significant difference among various groups. Probably hypolipidemic effect of palm seed is due to the presence of oleic acid and linoleic acid and its hypoglycemic properties is due to the elements such as magnesium and zinc which stimulate the synthesis and secretion of insulin. Manganese also mimics insulin properties

[Subpubic block in superficial operations of peins]

Circumcision is the most common surgical procedure. As same as other superficial operations, they cause not only severe postoperative pain but also are accounted a severe intraoperative stimulation. There are many anesthetic techniques for circumcision. It seems supplementary penile block to general anesthesia is the best approach. Our aim in this study is to evaluate the efficacy of sub pubic approach to dorsal penile nerve block in relieving postoperative pain. This descriptive study was done in Dr Sheikh Pediatric Hospital during summer of 2004. Sub pubic approach to dorsal penile nerve block was evaluated in 60 boys. Two injections were performed with plain Bupivacaine 0.5%, 0.1 ml/kg in each side [total 0.2 ml/kg] at puncture sites, which had been marked before, just 0.5 to 1 cm blow pubic symphisis and lateral to midline in the supine position. Postoperative pain was evaluated with two methods, FLACC and Wong and Baker, and parental report up to 24 hours after general anesthesia. Collected data was analyzed by using descriptive and analytical statistics. Two cases [3.3%] were excluded. Two patients [3.4%] experienced moderate pain postoperatively. Others [96.5%] were completely pain free up to 24 hours after procedure. No complications occurred. There was no relationship between needle length and patients' age. According to this and previous studies, although there is little experience, this technique is the most successful and safe approach for intra and postoperative long [up to 24h] pain relief that with some experience is also very easy
