Abstract:
1. Studies were performed regarding the effects of aluminum chloride and aluminum nitrate in concentrations of 5 mg/kg of body weight on the delta aminolevulinic acid dehydratase activity, iron level and hematological parameters. Wistar rats were exposed to these pollutants for 10, 20, 40 and 80 days. 2. The results demonstrated that aluminum chloride was more toxic than aluminum nitrate and both treatments brought about significant changes in these parameters in Wistar rats bone marrow. 3. The toxic effects of aluminum chloride and aluminum nitrate are manifested by a significant decrease of delta aminolevulinic acid dehydratase activity in the bone marrow of rats. 4. The iron level in bone marrow with aluminum chloride and aluminum nitrate gradually dropped after 10, 20, 40 and 80 days of intoxication. 5. In the peripheral blood a significant decrease in the erythrocyte count, hemoglobin level, hematocrit value and an increase in mean corpuscular hemoglobin (MCH) were also found in experimental animals.

02:23Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

Reducing carboxylic acid derivatives like acyl chlorides (RCOCl), esters (RCO2R′), and nitriles (RCN) using milder aluminum hydride agents like lithium tri-tert-butoxyaluminum hydride [LiAlH(O-t-Bu)3] and diisobutylaluminum hydride [DIBAL-H] allows...
01:19Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
01:17Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
01:20Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
00:55Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
