Effect of bread making process on heavy metals content of Egyptian breads

A total of 105 samples of flour, dough and bread from 35 bakery units were selected from various areas of Cairo The contents of lead [Pb], cadmium [Cd], cupper [Cu] and iron [Fe] were determined using atomic absorption spectrophotometer. Effect of breadmaking process was evaluated regarding heavy metals content. Results showed that slight increase of heavy metals content in flour compared to [Codex], i.e., Pb ranged between 0.177 - 2.98mg/kg m. Balady bread and ranged between 0.480 - 2.860mg/kg in Fino bread [0.5 mg/kg] while Cd ranged between 0.093 - 0.197 mg/kg in Balady bread and ranged between 0.071-0.176mg/kg in Fino bread [0.1 mg/kg]. Heavy metals increased as flour extraction increased .Also heavy metals content affected by breadmaking process. Breads had higher content of heavy metals than its dough or flour. Balady bread had higher content of determined heavy metals than Fino bread

Experimental study of biochemical effects of insecticides in albino rats

To detect the acute toxicity of some insecticide rats were divided into ten treatments each one contained six rats. These rats administered a single oral dose of 1/10 LD[50], 1/4 LD[50] and the LD[50] of primiphos-methyl, Chlorpyriphos-methyl and fenitrothion. After 24 hr treated rats were sacrificed. The activity of some biochemical parameters glutamic oxaloacetic transaminase [GOT], glutamic pyruvic transaminase [GPT], alkaline phosphatase [Alk. Ph.], creatinine, urea, total protein and total cholesterol] were detected in blood serum. The results indicated that all treatments caused significant increase in the activity of GOT, GPT and [Alk. Ph.], as well as the level of creatinine, urea and total cholesterol as compared by control ones. While the results indicated that 1/4 LD[50] and 1/10 LD[50] of the three tested insecticides caused significant decrease in total protein concentration. These detected differences observed on values between enzymes tested of liver and kidney function by increase or decrease it is considered a sign and pronounced that treated animals affected by oral dose through 24 hr

Pharmacokinetics effects of some insecticides on white albino rats

The treatment of adults' female albino rats with Maximum Residue Limit [MRL] to tomato fruits of the three organophosphorus insecticides namely, primiphos-methyl, chloriphos-methyl and fenitrothion [1, 0.5 and 0.5 ppm] respectively on different periods [from 1. 6, 12, 24, 48, 96 hours and 7 days] to indicate and follow-up the effect of these insecticides on liver and kidney functions. A significant increasing activities of Aspartate Amino Transferase [AST] were found. No changes in Alanine Amino Transferase [ALT] and Alkaline phosphatase activities were observed in treated rats by the MRLs of the tested insecticides as compared with control. The data gathered showed that there were no significant changes in creatinine levels and urea concentrations of the treated rats at the different periods after dosing by the MRL of the tested insecticides. The data also clearly indicated an insignificant decrease in total protein levels, observed in rats treated by MRL of the tested insecticides after 1, 6, 12, 24, 48, 96 hrs and 7 days of treatment. Cholesterol level displayed slight or insignificant increasing in rats which were treated with the aforementioned insecticides. Generally treating rats by MRL of the prementioned insecticides resulted in a small [deleterious] effect on some biochemical parameters after 7 days of treatment. No effects have been detected at the first hours of the experiments

Effect of C14 ethoxy profenofos insecticides on liver and kidney functions of lactating goats

Egyptian healthy baladi goats at the middle of lactating period were classified into two groups, the first group G[1] was kept as non-treated control, while the second group, 6 goats were orally administered the calculated C[14] -Ethoxy profenofos at a dose level 17.9 mg/kg /Body weight/day for 7 successive days. After stoppings of toxicant administration, three goats G2 were sacrificed and the other three animals' G3 were given normal feed for 14 days. Blood samples were taken for determine liver and kidney functions. The distribution of C[14] activity in liver, kidney, fat and muscle tissues showed that the tested organs in G2 contain more C[14] -activity than those in G3. The C[14] -residue levels were found to be high in liver and kidney than in fat and muscle tissues. Significant changes were noticed in GOT, GPT, alkaline Phosphatase, cholesterol, albumin, urea and creatinine during the toxicant administration and returned towards normal values after 14 days recovery
