Résumé
The study comprises the pharmacological trials with essential oils of Caesulia axillaris, Ocimum gratissimum and Mentha arvensis which have shown strong antifungal property. The biochemical analysis of blood and serum of albino rats fed with the oil treated diet for sixty days exhibited nonanimal toxic nature of the oils. The study reveals the possibility of further exploitation of the oils as safe antifungal agents of plant origin.

Adult male albino rats were orally administered 0, 25, 50 and 100 ppm of lead nitrate, mercuric chloride and cadmium chloride for 60, 120 and 180 days. The plasma sodium levels were decreased in rats exposed to varying doses of lead and mercury up to 180 days, while animals which consumed cadmium chloride showed an increase in sodium levels. In lead and mercury treated animals, plasma potassium levels were increased up to 180 days. The levels were decreased in cadmium exposed rats. These observations suggest that chronic exposure to these heavy metals considerably influences plasma sodium and potassium levels depending on the dose and duration of exposure.

In patients of chronic myeloid leukemia blood adrenaline, noradrenaline, dopamine and glutamate level were significantly elevated. The GABA levels were decreased along with no significant alterations in aspartate levels in these patients. In cases of acute myeloid leukemia only adrenaline and glutamate levels were enhanced with decreased GABA levels. However, plasma cortisol levels were significantly enhanced in both chronic and acute myeloid leukemia patients. These observations suggest that the circulating bioamines, cortisol and certain aminoacids level are considerably altered in chronic and acute myeloid leukemia. All these changes may possibly be attributed to the stress induced by the disease.

In eighteen normal healthy volunteers, the effect of cigarette smoking, coffee drinking and alcohol consumption on adrenomedullary sympathetic function was assessed in terms of urinary VMA levels. Following the indulgence in all these social habits, urinary VMA levels are significantly increased. The maximum and minimum increase in VMA levels were recorded following coffee drinking and alcohol consumption respectively.
