ABO and Rh blood groups were studied in a total of 1680 patients with cardiovascular diseases (congenital n=547, valvular n=887 and coronary n=246). Statistical analysis (X2and Woolf’s Test) showed significant excess of B/O in mitral valve, aortic valve total valvular diseases and heart diseases generally, also an increase of A/O in myocardial infarction. Significant increase of the frequency of Rh(D) positive individuals, was shown in myocardial infarction and total heart diseases.

A total number of 66 chorionic villus samples were cytogenetically investigated. The samples consisted of 30 experimental cvs from spontaneously aborted materialand 36 from live gestations.80% of the samples were successfully grown, of the 30 cases 40% (12) and 33% (10)contained a normal female and a normal male karyotype, respectively, 3.3% (1) and3.3% (1) had abnormal karyotypes (47,XX, + 21; 47, XY, + 18), respectively, and 16% (6) of the cultures did not grow of the 36 CVS, 80. 5% of the trophoblasts grew. 50% and 30.5% had normal karyotypes with 46, XY and 46, XX chromosome constitutions respectively, of those with a male karyotype, one case was revealed to have two mitoses with 47+Xy, +21 karyotype and was considered to be a Mosaic with a minor abnormal clone. One case (2.7%) was a twin; 5.5% of the samples did not grow and 11.1% of the villi were inadequate. No serious complications occurred after CVS. 12 girls and 9 biys were delivered at term and cytogenetic findings on the CVS were postnatally confirmed for normal cases and even for a Mosaic case.

Visceral leishmaniasiam caused by Leishmania infantum has become endemic in Meshkjn-Shahr area, northwest Iran, so that in the last 8 years, more than 1600 cases have been diagnosed and treated, the majority of them among children younger than 5 years of age. The present study was carried out to determine the probable vectors in this area. During the active season of sandflies in l991,we collected sandflies from fixed catching sites by sticky traps. The result shows that sandflies were active from mid-June through mid-October the following species have been caught in this area: Phiebotomus papatasi, Ph. sergenhj, Ph. caucasjcus Ph. ‘nongolensis Ph.alexandrj, Ph. kande/akii, Ph. major. Ph.perfj/jewj transcaucasjcus Ph. kech ishiani, Ph. ha/epensis, Ph. ba/can icus, Ph. brevis, Sergen tomyia dentata, Spa wlowskji and S.sumbarjca As many of these are potential vectors, dissection was made in 1991 and 1992 on gravid and blood- fed flies caught by sticky traps and CDC light traps. We found promstigote infection in 2 Ph.kandelakjj and 2 Ph. perfiliewi transcaucasicus Hamster inoculation of one strain caused massive visceral infection. Further studies are planned to identify other probable vectors and also the principal definite vector.

An investigation was made to study the residual activity and air- borne effect of pirimiphos- methyl, at 2g a.i./m2 in hut scale trials on different surfaces in kazeroun, and Bandar-Abbas, south of Iran. In Kazeroun area, bio-assay contact mortality test with pirimiphos methyl on mud, wood, cement and plaster surfaces, 54 days after hut spraying, decreased from 100% to 46.7%, 61.25%, 36.6% and 40%, respectively. In Baridar-Abbas area, after 72 days of hut spraying, the mortalities on cement and plasters surfaces decreased from 100% to 63.4% and 45.4%, respectively. The fumigation effect of pirirnlphosmcthyl on mud and plaster walls with wooden ceiling were studied in Kazeroun. ‘The activity of pirimiphos- methyl on mud and plaster surfaces dropped from 100% to 52% and 46.53% after 54 days of hut spraying respectively. The results suggested that pirimiphos-methyl has effective contact and vapour effect at least for about 50 days on different surfaces in south of Iran.

In order to determine the vector of visceral leishmaniasis in the endemic focus of Fars Province in southern Iran, collection and dissection of sand- flies were carried out in the town of Ghjr in Firooz - abad district. A total of 270 sand- flies were dissected. They consisted of Ph. Alexandri, Ph. sergenti Ph. papatasi and Ph. major. Five out of 150 Ph. major was found infected with promastigotes three of them with the parasites in the gut as well as the head. This is the first report about the probable vector of kala - azar in Iran.
