Orchidectomy affects the innervation of the rat thymus
(Gordon Breach Sci Publ Ltd, Reading, 1999)
To assess a putative role of the neural pathways in transfer of information from the gonads to the thymus, adult AO rats were orchidectomized (ORX) or sham ORX (controls); sacrificed 1, 3, 7, or 15 days later and their ...
Spectrophotometric and electrochemical study of protolytic equilibria of some oximes-acetylcholinesterase reactivators
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Newly synthesized oximes, mono and bis imidazole derivatives, which promise to be more effective acetylcholinesterase reactivators than standard antidotes used, were investigated by spectrophotometric and electrochemical ...
Simple and rapid method for the measurement of nitrite and nitrate in human plasma and cerebrospinal fluid by capillary electrophoresis
(Elsevier Science BV, Amsterdam, 1999)
Nitrite and nitrate levels in physiological fluids are commonly used as an index of nitric oxide production. We developed simple and rapid method for the determination of these anions by capillary zone electrophoresis ...
Determination of some insect repellents in cosmetic products by high-performance thin-layer chromatography
(Elsevier Science BV, Amsterdam, 1999)
A simple and reliable thin-layer chromatographic method for the determination of N,N-diethyl-m-toluamide (DEET) and dimethyl phthalate (DMP) in raw material and cosmetic products was developed and validated. A benzene-diethyl ...

(Journal of Essential Oil Research, 1998)
Achillea chrysocoma Friv. (Asteraceae) is an endemic plant of the Balkan peninsula. Herb of this yarrow contained up to 0.2% of essential oil. The oil was analyzed by GC and GC/MS and 48 of the 79 detected peaks were ...
Comparison of spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablets
(Wiley, 1998)
Spectrophotometric and UV-densitometric methods for the determination of celiprolol hydrochloride in tablet formulations were compared. Celiprolol hydrochloride and benzylorange react in a 1:1 ratio in the presence of ...
Effect of fillers and lubricants on acetylsalicylic acid release kinetics from Eudragit matrix tablets
(Marcel Dekker Inc, New York, 1997)
The effect of fillers and lubricants on the dissolution rate of acetylsalicylic acid (ASA) from matrix tablets has been evaluated. Eudragit S-100 and Eudragit L-100-55 where chosen as matrix substances. The process of drug ...
Spectrophotometric study of diclofenac-Fe(III) complex
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A multifactor optimisation technique is successfully applied to develop a new spectrophotometric method in which diclofenac sodium is analysed and determined as it's Fe(III) complex. The effect of simultaneously varying ...
