“…Negative stress can result in micronutrient deficiencies, and psychological and medical problems, and the psychophysiological consequences of deficiencies in micronutrients can lead to stress-related symptoms and reduced stress tolerance. By restoring the nutritional balance in such subjects, health-related problems as well as stress can be managed more adequately (Bayer & Schmidt, 1991a, 1991bGlathaar, 1999;Ranck, 1984;Kirov, 1991;Lettko & Meuer, 1990;Pietrzik, 1985;Popovic, 1993;Schiewner, 1995;Schlebusch et al 2000;Seelig, 1994;Selishchev, Pethot-Bacque, Volkov, 1998;Willemsen, Pethot-Bacque, Alleume, Suter, Ring, Carroll, 1997).…”

The development of a stress measure, and indications of its reliability and validity are reported in the present article. The human stress response and its deleterious consequences are discussed, includinq the fact that stress is a major problem in society at all levels of human interaction. South African stress levels are particularly high, and many lifestyle diseases, health-risk behaviours, suicidal behaviours, violence, trauma-producing behaviours, performance levels and difficulties in coping with change are stress-related, as are numerous medical, psychological and/or psychiatric disorders. Given this, a Stress Symptom Checklist (SSCL) was constructed as a user-friendly stress measurement. It was developed as part of a major stress research initiative. The aim was to produce an authoritative, reliable and valid stress checklist that can stand up to critical inspection, yet be an easy-to-use measure. It focuses on the respondent's stress level rather than on the stimuli leading to that stress. It is not intended to be a diagnostic tool that measures specific stress-related psychopathological conditions or disorders, but rather the intensity (or severity) of stress as reflected by an individual's physical, psychological and behavioural reactions. To date, the data show that the SSCL is a useful measure of non-pathological stress in the general population. Further refinements and validation studies are in progress.

A sixty-day feeding trial was carried out to elucidate the effect of dietary pyridoxine (PN) on hemato-immunological parameters in Labeo rohita fingerlings exposed to an elevated temperature (ET) of 33 °C. Two hundred and seventy fingerlings (6.71 ± 0.32 g) were randomly distributed into six treatments in triplicates (15 fish/tank). Five iso-nitrogenous (356.3 ± 2.7 g/kg crude protein) purified diets were prepared with graded levels (0, 10, 50, 100 and 200 mg/kg diet) of PN. Six treatment groups were P10T26 (10 mg PN + ambient temperature (26 °C), P0T33 (0 mg PN + ET), P10T33 (10 mg PN + ET), P50T33 (50 mg PN + ET), P100T33 (100 mg PN + ET) and P200T33 (200 mg PN + ET). The responses of L. rohita fingerlings to dietary PN were assessed in terms of growth and by analysing some hemato-immunological parameters. When PN supplementation increased from 10 to 200 mg/kg diet, a significant improvement in weight gain percentage was observed. Erythrocyte (RBC) count, leucocyte (WBC) count, haemoglobin content and respiratory burst activity were significantly (p < 0.05) higher in 100 mg PN/kg diet-fed group than their non-PN-fed counterpart. Also, serum albumin, globulin and lysozyme activity were found significantly (p < 0.05) higher in PN-fed groups. The overall results indicated that dietary PN supplementation at 100 mg/kg diet may reverse the negative effects caused by ET and may protect the haemato-immunological status of L. rohita fingerlings reared at higher water temperature.

The amelioration effect of water-soluble vitamin pyridoxine against stress was evaluated in milkfish, Chanos chanos exposed to endosulfan. Two hundred and twenty-five fish were distributed randomly into five treatments, each with three replicates. Four isocaloric and isonitrogenous diets with graded levels of pyridoxine feed were as follows: normal water and fed with control diet (En0/PY0); endosulfan-treated water and fed with control diet (En/PY0); and endosulfan-treated water and fed with 50 (En/PY 50 mg/kg), 75 (En/PY 75 mg/kg) and 100 mg/kg (En/PY 100 mg/kg) pyridoxine-supplemented feed. The endosulfan in treated water was maintained at a level of 1/40th of LC50 (0.52 ppb). The effect of dietary pyridoxine supplementation was studied in terms of antioxidative enzymes (catalase, superoxide dismutase, glutathione-S-transferase), stress markers [heat-shock protein 70, caspase-3, cortisol, acetylcholine esterase (AChE), blood glucose], immunohaematological parameters (total protein, albumin, globulin and A/G ratio, nitroblue tetrazolium, RBC, WBC, Hb), gill histopathology and a subsequent challenge study with Vibrio parahaemolyticus. The antioxidative enzymes, stress markers, albumin and A/G ratio were significantly (p < 0.01) elevated, brain AChE and immunohaematological parameters were significantly (p < 0.01) decreased, and chromosome aberration and gill histopathology were also altered due to endosulfan exposure. The relative survival % was reduced due to the combined effect of endosulfan stress and bacterial challenge. Fish fed the diet supplemented with pyridoxine at 75 and 100 mg/kg was found to restore the studied parameter towards normal compared with control and indicated protection against endosulfan-induced stress significantly (p < 0.01). Results obtained in the present study indicate that the supplementation of 75 and 100 mg/kg of pyridoxine in the diet has a definitive role in the mitigation of the endosulfan-induced stress in milkfish, C. chanos fingerlings.
