Abstract
Analytical methods for drug substances, formulations, and clinical samples developed and validated on HPTLC plates during the period 1996-2009 are reviewed. Procedures, materials, and instrumentation for the different steps in the HPTLC procedure and validation of results; applications to bulk drugs, formulations, stability studies, biological samples (e.g., urine and plasma), and hydrophobicity studies; and prospects for the use of HPTLC for drug analysis in the future are described.

Abstract
Applications of thin layer chromatography and high performance thin layer chromatography for the separation, detection, qualitative and quantitative determination, and preparatire isolation of pesticides and their metabolites are reviewed for the period from July 1, 2006 to November 1, 2008. Analyses are described for a variety of sample types and pesticide classes. In addition to references on residue and formulation analysis, studies such as pesticide-structure relationships, identification and characterization of plant pesticides, metabolism, degradation, mobility, and lipophilicity are covered. Future prospects for pesticide thin layer chromatography are also considered.

Abstract
Silica gel high performance thin layer chromatography-densitometry was used to determine the neutral lipid profile in the urine of BALB/c mice experimentally infected with adults of Echinostoma caproni. An approximate 30 worm burden per host induced certain changes in the neutral lipid profile of the mice at 2 to 10 weeks post-infection (PI) relative to the uninfected controls. Infection caused a significant increase (Student's t test, P < 0.05) in the methyl oleate fraction at 6 and 7 weeks PI relative to the uninfected controls. Neutral lipid profiles of urine may serve as an indicator of experimental infection of echinostomes in mice.

Abstract
High-performance liquid chromatography (HPLC) was used to determine the effects of a patent Schistosoma mansoni infection on certain carboxylic acids in the digestive gland gonad complex (DGG) and hemolymph of Biomphalaria glabrata. An analysis of DGG samples was done using extraction with 50% Locke's solution, cleanup of the extract by anion exchange solid phase extraction (SPE), and ion exclusion HPLC with ultraviolet detection. Hemolymph was applied directly to the SPE column. Acetic, fumaric, malic, and pyruvic acids were detected, confirmed, and quantified at concentrations ranging from 12 to 280 ppm in the DGG and less than 124 to 8,000 microg/dl in the hemolymph. Infection with S. mansoni caused a significant reduction (Student's t test, P < 0.05) in the concentrations of acetic, fumaric, malic, and pyruvic acids in the DGG but not the hemolymph of B. glabrata compared to uninfected cohort snails. The significant reduction of certain carboxylic acids in the DGG of B. glabrata patently infected with S. mansoni suggests that these acids are utilized by the sporocysts and cercariae in the snail tissue, or that the infection stimulates reduced production or increased utilization by the snail tissue.

Abstract
Applications of thin layer chromatography and high performance thin layer chromatography for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds are reviewed for the period from July 1, 2004 to November 1, 2006. Analyses are covered for a variety of samples, such as food, crops, biological, environmental, pharmaceuticals, and formulations, and for residues of pesticides of various types, including insecticides, herbicides, and fungicides, belonging to different chemical classes. In addition to references on residue analysis, studies such as pesticide-structure relationships, metabolism, degradation, and lipophilicity are covered, many of which make use of thin layer radiochromatography.

Abstract
The effects of aestivation or starvation on the neutral lipid and phospholipid content of Biomphalaria glabrata patently infected with Schistosoma mansoni were determined by high-performance thin-layer chromatography-densitometry. Infected-aestivated snails were maintained in a moist chamber at 24 +/- 1 C and a relative humidity of 98 +/- 1%. Infected-starved snails were maintained in artificial spring water (ASW) at 23 +/- 1 C without exogenous food. Infected snails (the controls) were maintained in ASW at 23 +/- 1 C and fed lettuce ad libitum. The 3 groups were maintained in the laboratory for 7 days, and then the lipids from the digestive gland-gonad complex (DGG) were extracted and analyzed by class. Infected-aestivated snails exhibited greater mortality rate and weight loss after 7 days than did the infected-starved snails. The steryl ester concentration in the infected-starved snails was significantly increased (P = 0.010) compared with the controls but not compared with infected-aestivated snails; the concentration of phosphatidylcholine in infected-aestivated snails was significantly decreased (P = 0.007) compared with the controls but not when compared with the infected-starved snails. Aestivation or starvation had a significant effect on the concentration of certain lipid classes in the DGG of B. glabrata infected with S. mansoni.
