“…Sodium and potassium ion levels in serum were determined using a flame photometer (Model 410 C, Petracourt Ltd, England) at a wavelength of 598 nm and 769 nm for sodium and potassium ions respectively (Mencaly et al, 1976). Chloride ion in serum was determined by end point colourimetric titration method (Visweswariah et al, 1972). Serum bicarbonate was estimated by titrimetric method (Mencaly et al, 1976).…”

The physiologic adaptations of the pregnant woman involve the renal, cardiovascular and other systems of the body. This study aimed at evaluating electrolyte concentrations in the three trimesters of pregnancy. Blood samples were collected by aseptic techniques and the concentrations of electrolytes were determined using standard laboratory methods such as titration for chloride and bicarbonate and flame photometry for sodium and potassium. Eighty healthy volunteers consisting of 20 non-pregnant control and 20 pregnant women in each of the three trimesters of pregnancy participated in the study. The sodium concentrations in mmol/L were 135.91 ± 3.00, 136.42 ± 3.11, 135.70 ± 2.90, and 136.30 ± 2.52, for control, first trimester, second trimester and third trimester subjects respectively. The potassium concentrations in mmol/L were 3.51 ± 0.18, 3.49 ± 0.11, 3.53 ± 0.20, and 3.50 ± 0.21, for control, first trimester, second trimester and third trimester subjects respectively. The chloride concentrations in mmol/L were 103.50± 3.21, 103.60± 2.92, 104.70 ± 3.10, and 105.0 ± 3.02, for control, first trimester, second trimester and third trimester subjects respectively. The Bicarbonate concentrations in mmol/L were 25.75 ± 1.51, 26.11 ± 1.17, 25.69 ± 1.72, and 26.10 ± 1.13, for control, first trimester, second trimester and third trimester subjects respectively. This study revealed that the electrolytes sodium, potassium, chloride and bicarbonate remained unchanged (p>0.05) as pregnancy advanced. This suggests that the kidneys are well adapted to the handling of electrolytes during pregnancy.

“…Sodium and potassium were estimated using a cunning flame photometric procedure as described by (Mencaly et al, 1976). Serum chloride was estimated by the colorimetric approach as described elsewhere by (Visweswariah et al, 1972), while serum bicarbonate was estimated by the titrimetric method as described by (Mencaly et al, 1976).…”

The investigation was undertaken to study some biochemical changes and cortisol levels in lameness among indigenous breeds of goats in Nigeria. Serum samples of 72 lame goats randomly selected were sampled from some villages in Ibadan, Oyo state, Nigeria. Analysis of the serum samples for biochemical parameters was estimated by commercially available standardized diagnostic kits. Glucose was analyzed using the spectrophotometry procedure. Cortisol level was estimated by Immuno chemiluminescence microparticle assay method using diagnostic products of IMMULITE diagnostic products corporation, Los Angles. Cross-bred goats possessed better values for most of the biochemical analytes, a significant difference was seen in ALT with a higher value of 14.5±3.54 in Cross-bred goats at (P<0.05). We found no significant difference in the male and female analytes, with the exception of AST, ALT, and GGT which have significant differences of higher values at (P<0.05) of 15.25±2.77, 12.06±2.02 and 8.69±2.21 respectively. There was a significant difference in the value of low-density lipoprotein with a higher value of 119.6±11.34 in the 2-2 1/ 2year age category. Severely affected lame goats had significant differences at (P<0.05) with higher values of some analytes as follows; K 3.4±0.37, Cl 100±3.54, HCO3 24.6±1.14, BUN 19.8±2.28, Creatinine 0.52±0.08, TP 6.48±0.15, Albumin 2.82±0.24. Cross-bred goats had the best value of 12.00±1.41 for cortisol. Male goats had the best cortisol value of 10.47±1.46. This study reveals the ruggedness and resilient ability of cross-bred goats which show that developing Nigerian indigenous breeds may be a viable option in the prevention and management of lameness in Nigeria.

The relationship between the spot concentration and the resolution of different components in commercial hexachlorocyclohexane with micro‐ and macro‐thin layer chromatography has been studied. Of the different spot concentrations investigated, only 0.025 μg on micro‐t.l.c. and 1.0 μg on macro‐t.l.c. gave two clear spots which can be made use of for the rapid semiquantitative estimation of benzene hexachloride in insecticide formulations. The application of this technique has been further investigated on different commercial benzene hexachloride dust formulations and the error ranged between 2 and 5%.
