RESUMEN
The identification of chromosomes for routine cytogenetic analysis is based on quality of metaphases and good banding pattern
Fresh slides of human lymphocytes have been shown to produce good bands for the identification of chromosomes morphology. G-bands by Trypsin using Giemsa [GTG] banding of aged slides is generally considered hard to get desired band pattern of chromosomes persistently. The current study is focused on GTG banding of aged slides. A total of 340 subjects including 290 primary infertile and 50 fertile were selected. The blood samples were drawn aseptically for cytogenetic analysis
Lymphocytes were cultured and GTG banding was done on 1440 glass slides
Giemsa trypsin banding of aged slides were done by adjusting average trypsin time for each month according to the slide age and metaphase concentration
Correlation analyses showed a significant and positive correlation between slide ageing and trypsin pre-treatment time. The results of this study suggest that, the fresh and aged human lymphocyte metaphases are equally usable for GTG banding
RESUMEN
A total of 160 faecal samples were collected from different Day Care Centres. The incidence of parasitic injections were as: Entamoeba coli 30.00%, E. histolytica 4.00%, Iodamoeba butschilii 6.00%, Isospora sp. 6.00%, Blaswcystis hominis 6.00%, Chilmoastic mesnili 2.00%, Enterobious vermicularis 4.00% and Ascaris lumbricoides 14.00%. Mixed injection was also observed. Different epidemiological factors were also thoroughly studied during this survey
