G-6PD deficiency in malaria endemic areas of Udaipur District in Rajasthan.

Nine thousand four hundred thirty three pyrexial cases were screened for the evidence of Malaria and Glucose-6-phosphate dehydrogenase deficiency among the rural tribal population of seven primary health centres in the malarial endemic areas of Udaipur District in Southern Rajasthan. One thousand four hundred five (P. Falciparum 831 and P. Vivax 574) cases were positive for malaria and 170 for G-6PD deficiency. Incidence of G-6PD deficiency in malaria, when compared to the non-malarial cases revealed statistically insignificant alterations (X2 is calculated to 0.1299 which for 1 degree of freedom gives P > 0.05).

Prevalence of hepatitis surface antigen among rural population of Loni area in Ahmednagar district of Western Maharashtra.

Three hundred and fifty three subjects among the rural population of Loni area admitted in the hospital, and 188 medical staff members working in the Rural Medical College and Hospital, Loni, were screened for the presence of HBsAg. Reveresed passive haemagglutination assay was used for screening; it showed an HBsAg positivity rate of 21.8% and 15.8% among hepatitis and non hepatitis cases respectively, and 1.2%, 0% and 4.2% among medical students, doctors and nursing staff respectively. A high HBsAg positivity rate has been observed in the rural population of Loni area.

Complement activation in pulmonary tuberculosis.

The alterations in serum/plasma levels of total haemolytic complement activity (CH50), complement components C3 and C3d, and circulating immune complexes (CICs) in patients with pulmonary tuberculosis were analysed in relation to the severity of disease and treatment status. The mean levels of CH50, C3, C3d and CICs were significantly higher in untreated than treated patients and in normal controls. In the untreated group, the level of each of these four parameters except C3d was significantly higher in patients with far advanced disease than in those with moderately advanced disease, whereas the difference between treated patients and normal controls was not statistically significant for any of the four parameters tested. There were statistically significant correlations between levels of CICs and both C3 and C3d in the untreated tuberculosis patients. However, the correlations for the same parameters were not significant when treated patients were considered. The CH50 levels in tuberculosis patients suggest a functional classical complement pathway, which is essential for immune complex solubilisation. High C3d level in untreated patients is indicative of increased complement activation, which in turn shows significant correlation with levels of CICs. It appears that the intact and elevated complement proteins and their proper activation by CICs prevents tuberculosis from becoming a typical immune complex disease.

Restriction endonuclease analysis of DNA in sickle cell lesions among tribals of Bihar, Madhya Pradesh, Gujarat & Rajasthan.

Restriction endonuclease analysis of DNA was undertaken in blood samples from individuals who were normal (110), had sickle cell trait (44) and homozygous sickle cell disease (6) from the tribal populations of Bihar, Madhya Pradesh, Gujarat and southern Rajasthan. DNA was prepared from all the blood samples and processed for restriction enzyme digestion, agarose electrophoresis, prehybridization, Nick-translation hybridization and autoradiography. A polymorphic HpaI restriction endonuclease recognition site on the 3' side of the beta-globin gene was used to analyse to determine the beta-globin gene mutant S. It was found that mutation has resulted within the normal 7.6 Kb HpaI fragment among the tribal populations studied. On comparing the results with those from Middle East and East Africa it appears that the sickle gene mutation in India, Saudi Arabia and Kenya arose separately from that in West Africa.

Sickle cell and thalassaemic genes in Libya.

An electrophoretic study of haemolysates from 1350 subjects from the indigenous population of Libya was carried out to find the incidence of abnormal haemoglobins and thalassaemia. Sickle cell disease was detected in five (0.37%), sickle cell trait in 61 (4.51%), sickle cell thalassaemia in three (0.21%), homozygous betathalassaemia in 16 (1.20%), heterozygous delta-beta thalassaemia in 25 (1.85%) and heterozygous beta-thalassaemia in 105 (7.77%). The incidence of the sickle cell gene is low, but that of the thalassaemic gene appears to be high in the Libyan population which is racially mixed, containing Arab, Mediterranean and Negroid types.

Haemoglobinopathies in Libya.

Electrophoretic study of haemolysates from five hundred and forty-five subjects from the University of Garyounis, Benghazi, was carried out to find out the incidence of abnormal haemoglobins in Libya. Abnormal haemoglobins were encountered in 23 subjects of unrelated families, giving an overall incidence of 4.2 per cent. Sixteen of these subjects had Hb-AS trait (3.0%), Five subjects had Hb-AC trait (0.9%) and two subjects had Hb-AD trait (0.36%). Present study indicates that the incidence of abnormal haemoglobins in the indigenous population of Libya is low.

Effect of garlic oil in experimental cholesterol atherosclerosis.

Addition of cholesterol in the diet of male albino rabbits produced hypercholesterolaemia, increased tissue cholesterol, and atheromatous changes in the aorta. Supplementation of garlic oil along with cholesterol significantly inhibited the hypercholesterolaemia, decreased tissue cholesterol and minimised the atheromatous changes in the aorta. These results show that the active constituent(s) in garlic responsible for its anti-atherogenic action is present in the oily fraction of garlic.
