Dopaminergic receptor regulates catecholamine release from perfused adrenal medulla

Nicotinic drug is a potent secretogogues for catecholamine from bovine adrenal glands perfused with oxygenated Locke's buffer. However, apomorphine, I IIM, [the dopaminergic agonist] markedly inhibit this catecholamine release by about 40%. Haloperidol 0.5 muM, [the dopaminergic antagonist] reversed the inhibitory effects of apomorphine. These data strongly suggested that, as in the cat, the bovine adrenal modulates the catecholamine cell contains a dopaminergic receptor that modulates the catecholamine secretory process triggered by stimulation of the nicotinic cholinergic receptor. This dopaminergic receptor might be involved in a sympathoadrenal cooperative mechanism

Tuberculosis and anemia of chronic infection

Male children aged 7-12 years with tuberculous cervical lymphadenitis alone or with other tuberculous lesion, were subjected to hemoglobin concentration, which was 9.5 g/dl and less in 15 patients. Serum iron, total iron binding capacity, serum ferritin and complete blood picture were performed to those 15 patients. There was 9 patients from 15 suffering from anemia of chronic infection. After antituberculous treatment, there was marked improvement to this anemia in 8 patients

Case control study of giardiasis in diarhoeas versus non diarrhoeal children aging 6-12 years

The aim of this work is to study the prevalence, the clinical presentation and the different methods of diagnosis of giardiasis among school children aging 6-12 years suffering from acute diarrhea. The prevalence of giardiasis was 26% and 6% in diarrheal and non- diarrheal children, respectively. Children with giardiasis were younger, without sex difference and in lower socioeconomic status that those without giardiasis. Simple stool analysis detected 43.8%, simple flotation method detected 68.8% while, duodenal aspiration detected 81.3% of giardia cases. Stools in giardiasis was offensive, pale whitish and not bloody. Offensive stool was the commonest manifestation [87.5%] followed by diarrhea [81.3%]. It was concluded that the clinical picture of giardiasis is suggestive and duodenal aspiration is a good diagnostic methods. Large scale study and duodenal biopsy are recommended
