background: vitamin a which is found in different tissuesand organs plays a particular role in detecting clinical signs invarious deficiency conditions. however, sometimes the marginaldeficiency is present in a way that clinical signs are not visible butperformance defects, such as infertility is seen. objectives: inthis study, the normal baseline levels of vitamin aand β-carotene inclinically ...

Nitrite intoxication occurs frequently in ruminants and equines. The most common treatment of this disorder is administration of 1% methylene blue, although the use of some antioxidant agents e.g. vitamins and complementary treatment may also be useful. The aim of this study was to evaluate the in vitro antioxidative effects of some vitamins on methemoglobinemia induced by sodium nitrite. For t...

Parsley root has been used medicinally since ancient times for possible medicinal qualities including antioxidative, antimicrobial, laxative, antihy-perlipidemic, anticoagulant and antihepatotoxic (1). The parsley importance is attributed to its high vitamins content (mainly vitamins C), anti-oxidants, and some mineral elements such as iron, as well as volatile oils that play an important role ...

bilirubinometer is somewhat more effective than clinical screening. If both transcutaneous index and clinical acumen were used simultaneously there would be considerably fewer false-positive screens. Discussion Previous studies evaluating the transcutaneous bilirubinometer have been carried out in Japan by Yamanouchi et al.,2 and in the USA by Hegyi et al.3 Hegyi et al.3 obtained a correlation ...

Streptococcus gallolyticus is often found as a normal member of the gut microflora of various animals, while it has been reported to cause mastitis in cattle, septicemia in pigeons, and meningitis, sepsis, and endocarditis in humans (2). The species, which includes strains formerly identified as Streptococcus bovis biotye I and S. bovis biotype II/2, can be distinguished from other related taxa...

I have been using the spectrophoto-metric assay of Cushman and Cheung (1) as modified by Lieberman (2) to assay for serum angiotensin-converting enzyme (ACE) in diagnosis of possible sarcoidosis. However, replicate determinations produced results that varied considerably, creating some doubt about its analytical usefulness. Taylor and Freeman (3) identified a cause of this variability as cloudi...

The effect of diethylstilboestrol (DES; 0.5 mg/100 g) and progesterone (2.5 mg/100 g) was studied on the catecholamine content of adrenals and uteri of seven day ovariectomized albino rats. The agents were administered i.p. on alternate days for one week and the tissue catecholamine content was determined spectrophoto fluorometrically. DES treatment increased the total adrenaline contents of ad...

This review article summarized the analytical methods for the quantitative determinations of H2 receptor antagonist famotidine by spectral methods, electrochemical procedures (potentiometric titration, polarography, diferential pulse voltammetry) as well as separation procedures such as high-performance liquid chromatography (HPLC), thin layer chromatography (HPTLC) and capillary electrophoresi...
