The preliminary cytogenetic investigations in Rana ridibunda Pall. and Rana esculenta L. from the north of Moldavia
Ciprian Radu Mandrescu,Gogu Gheorghita
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2008,
Abstract: The cytogenetic investigations in Rana ridibunda (Pall.) and R. esculenta (L.) species pointed out that the two species have the karyotype formed of 13 pairs of chromosomes (2n = 26). The chromosomes of these species can be divided into two groups: the first group comprises the pairs of large chromosomes 1–5, and the second group is made of the pairs 6–13 of smaller chromosomes.
MORPHOGENETICAL AND HISTOLOGICAL STUDIES OF IN VITRO” ANTHER CULTURES OF BRASSICA OLERACEA L.
Daniela Nicuta,Irina Toma,Gogu Gheorghita
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2005,
Abstract: The anthers were inoculated on 8 hormonic variants of MS (Murashige-Skoog, 1962) medium and on one variant of B5 (Gamborg, 1968) slightly changed medium formula. The main morphogenetic reaction was callus formation. The callus’s consistency and colour differed depending on the hormonic variant. The friable callus for all the tested genotypes had caulogenetic capacity. Its passage on differentiation media comprising cytokinins led to new shoots formation, the intensity of this phenomenon varied with the genotype and with the initial medium that provided the respective callus. The histological studies of calluses or of anther shoots pointed out callus structure and the numerous histogenetic stages due to growth regulators, as well as in vitro regenerated shoots’ structure.
SOME CONSIDERATIONS REGARDING THE IN VITRO BEHAVIOUR OF BASIL (OCIMUM BASILICUM L)
Daniela Elena Maftei,Gogu Gheorghita,Daniela Nicuta
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2006,
Abstract: In vitro cultures of basil were initiated using shoot tips from plants grown in the laboratory. It was noticed that shoot tips and nodes’ inoculation on MS medium supplemented with cytokinins, auxins or with cytokinins combined with auxins induces caulogenesis and root generation, providing neoplantlets. Adding only 2,4-D or 2,4-D combined with a cytokinin to the nourishing medium, the main reaction of the explants (nodes, internodes, roots, leaves) was formation of compact, non-proliferative, green-whitish callus. An in vitro micropropagation technology was perfected for our investigated species, useful to multiply valuable genotypes.
Biochemical investigations on Rana ridibunda Pall. and Rana esculenta L
Ciprian Radu Mandrescu,Gogu Gheorghita,Vlad Artenie
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2009,
Abstract: Our investigations pointed out the existence of a high variability of some biochemical indices in the hepatic, muscular and blood tissue at Rana ridibunda Pall. and Rana esculenta L. Higher amounts of sugars and transaminases were found in the tissues of Rana esculenta L. species, while Rana ridibunda Pall. was characterised by higher levels of fats (triglycerides and cholesterol). With some exceptions, the highest values of the analysed biochemical indices were found in blood. The electrophoresis of plasma blood proteins of the two species of green frogs showed the presence of 3 4 proteic fractions in blood. The albuminic fraction at Rana esculenta L. contains two sub-fractions, and this fact sustains the idea of a hybrid nature of this species.
DOWN SYNDROME IN BACAU COUNTY
Aura-Manuela David,Gogu Gheorghita
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2005,
Abstract: According to a study on a lot of 27,623 children from Bac u county 23 cases of Down syndrome were found – 7 girls and 16 boys. This syndrome has been found at children between 2 months and 10 years old. These cases are coming from the rural environment – 16 cases and from the urban environment – 7 cases. Among the children with Down syndrome, who had also congenital malformations of the heart, it has been noticed that 3 deceases occured at boys under the age of 1 year.
Some cytogenetic effects induced in barley by the treatments with hydroalcoholic rosemary extract
Ionela Daciana Mierlici,Gogu Gheorghita,Gabriela Capraru
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2009,
Abstract: The paper presents some results regarding the cytogenetic effects induced in barley by the treatments with rosemary extract (Rosmarinus officinalis). It was proved that the treatment with this extract upon the barley caryopses had as effect the stimulation of the mitotic division in the radicle apex of the species and did not lead to important cytogenetic changes (chromosome aberrations) in the ana-thelophase of the radicle mitoses.
HAEMOPHILIA IN BACAU COUNTY
Aura-Manuela David,Gogu Gheorghita
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2005,
Abstract: : It has been made a research by comparison of the cases of haemophilia at infants from Bac u county. During 1998 – 2003 6 cases of haemophilia were discovered amongst a lot of 27,623 subjects that have been investigated. The 6 cases of haemophilia found and confirmed are distributed as it follows: 3 cases of haemophilia type A, 2 cases haemophilia type B and one case of vascular haemophilia. These cases are children of age over 10 years old and who come mostly from the urban environment
The activity of some oxidoreductases in Hordeum vulgare L. plants treated with ethylmethanesulfonate and Rosmarinus officinalis L. hydro-alcoholic extracts
Ioana Daciana Mierlici,Elena Ciornea,Gogu Gheorghita
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2010,
Abstract: This paper focuses on the activity of some oxidoreductases (catalase, peroxidase, superoxide- dismutase) in barley seedlings (Hordeum vulgare L.) after 6 hours of seeds treatment with different concentrations (0,01 – 0,50%) of ethyl-methane-sulfonate and 12 hours with hydro-alcoholic 0,5% rosemary (Rosmarinus officinalis L.) extract (EHR). The EMS treatments led to an obvious increase of the superoxide dismutase, catalase and peroxidase activity in plants, while the application of the hydro-alcoholic rosemary extract, after the EMS treatment, led to a significant decrease of the activities of these enzymes, since the rosemary extract has an obvious antioxidant effect.

Gogu Gheorghita,Daniela Nicuta,Simona Mireanu,Diana Elena Ionica
Analele ?tiin?ifice Ale Universit??ii Alexandru Ioan Cuza din Ia?i,Sectiunea II A : Genetica si Biologie Moleculara , 2003,
Abstract: This paper presents the m orphogenetic reaction of different explants of Brassica juncea Czern. Species in “ in vitro” cultures. The obtained results showed that the m icropropagation of this plant could be recomm end only for m ultiply ing some valuable genotypes.
