The complete nucleotide sequence of the gene for chain c of hemoglobin of the earthworm Lumbricus terrestris has been determined. The sequence of 4037 base pairs (bp) includes about 310 bp of 5'-flanking sequence and 110 bp 3' to the poly(A) site. Comparison of cDNA and genomic sequences shows four silent differences in codons that suggest the presence of at least two genes. The coding sequence...

The complete dissociation of the hexagonal bilayer structure of Lumbricus terrestris hemoglobin (3900 kDa) at neutral pH, in the presence of urea, guanidine hydrochloride, sodium perchlorate, potassium thiocyanate, sodium phosphotungstate, and sodium phosphomolybdate, followed by gel filtration at neutral pH on Sephacryl S-200 or Superose 6, produced two fragments, II (65 kDa) and III (17 kDa);...

The fine structure of obliquely striated muscle fibres from the body wall of the earthworm has been investigated. Certain details of the structure have been confirmed by cutting serial sections. The fibres contain both thick and thin myofilaments. The latter are attached to Zmatenal and the 2 types of myofilament are arranged in interdigitating arrays to give rise to Aand I-bands and an H-zone ...

The earthworm Lumbricus terrestris is an anecic species living in natural soils but it also a sentinel pollution monitoring. Specimens of L. were exposed for 48 h though the filter paper contact test at 1 mg/mL chemicals: Lamotrigine (LMG), Cocaine (COC), Fipronil (FIP) and pesticide bis-4-nitrophenyl phosphate (BNPP). After that period, activities Acetylcholinesterase, Glutathione S -transfera...

The aim of this study was to find out the nutritional value of some selected plants of family Zygophyllaceae and Euphorbiaceae which are traditionally used in different parts of Pakistan. The five plants Fagonia cretica L., Peganum harmala L., Tribulus terrestris L., Chrozophora tinctoria (L.) Raf. and Ricinus communis L., were collected from Peshawar and Attock Hills during winter, 2009. In th...
