The  study aimed to determine the effect of chitosan on  the kidney of rats (Rattus sp.) exposed to lead acetate. Thirty five male animals weighing 250g were divided into 7 groups:  K group as a control (without treatment), P1  received  Pb (40 mg/kg bw as lead acetate),  while P2, P3, and P4, all received Pb (40 mg/kg bw) and chitosan (0,5%, 0,75%, and 1% respectively). P5 group received only chitosan (1%) and P6 group received acetic acid. After 7 weeks of  treatment, the animals were sacrificed and the kidneys were isolated. Kidney damage was observed with residue of Pb in kidney tissue was evaluated using Atomic Absorption Spectrophotography. Chitosan able to decrease kidney damage resulted from  Pb treatment. Residue of Pb in the  kidney of rat exposed to Pb acetate was decreased after chitosan treatment. In conclusion, chitosan has the ability to reduce residue of Pb after exposed Pb. The effectiveness of chitosan as a chelating agent for Pb in the organs is important  for   further investigated. Keywords: Pb, chitosan, kidny, residual Pb,AAS

The diazo method of Hunter for the determination of ergothioneine in simple solution has been adapted to the Evelyn photoelectric colorimeter. The application of the method to the determination of ergothioneine in blood is described. Suitable blood filtrates are prepared by deproteinization with standard acetic acid oxalate solutions followed by removal of reduced glutathione with Goulard's lead acetate solution, and removal of excess lead with phosphate. By the method precise recovery is obtained of ergothioneine added to human blood.

ABSTRACTWe report a robust method by which colloidal PbS nanosheets can be synthesized with nearly 100% success rate. It is achieved by replacing the lead acetate by lead oxide for preparation of the lead precursor. Acetic acid either injected externally or produced during the reaction can significantly affect the growth of the nanosheets. The existence of water in the reaction solution makes the nanosheets smaller in lateral size while the purity of trioctylphosphine has no significant effect on the nanosheet growth.

Rapid Procedure

Abstract A new method for the determination of aflatoxins in cottonseed is presented and compared with two other procedures. This procedure yields good recovery for added aflatoxin, is relatively simple and rapid, and produces relatively clean extracts for TLC. A 75 g sample of ground cottonseed or cottonseed meal is extracted with aqueous acetone, centrifuged to remove solids, treated with lead acetate and acetic acid to precipitate interfering substances, and recentrifuged. An aliquot of the supernatant is mixed with powdered cellulose and packed into a chromatographic column for liquid-liquid partition chromatography. Hexane elutes the lipid materials; the aflatoxins are eluted with a hexane-chloroform mixture. After solvent evaporation, the aflatoxin-containing residue is dissolved in chloroform and chromatographed by TLC. Silica gel is the adsorbent; a benzeneethanol-water mixture is the developing solvent. The aflatoxin content is estimated by comparison with standard aflatoxins.
