Confirmation of herpes simplex virus (HSV) from genital lesions of obstetrical (OB) patients may affect both the management of the delivery and of the neonate.(l,2) During 1992 and 1993, 4,450 genital specimens from OB patients were submitted in viral transport media for herpes culture. The specimens were inoculated into MRC-5, Vero, and A-549 tissue culture tubes, incubated, and examined daily for 7 days for cytopathic effect (CPE). The original specimens were frozen at −70° C until final reports were issued. Culture tubes with CPE were tested by the Dupont Herpchek enzyme immuno assay (EIA) to confirm the presence of herpes simplex virus (HSV). (3,4) 170 OB patient specimens were positive by culture and confirmed by EIA.There were also 63 cultures exhibiting CPE ressembling HSV which were negative by EIA testing, which failed to pass in fresh tissue culture cells or progress to more enhanced CPE in culture. These original specimens were screened by electron microscopy after direct ultracentrifugation employing the Beckman airfuge with the EM 90 rotor on to formvar carbon-coated 300 mesh copper grids and negatively stained with 2% PTA.

The aim of the present hospital based study is to assess the serum levels of 8-hydroxy-2’-deoxyguanosine (8-OHdG) among 152 subjects. A total of 152 subjects, categorized into 3 groups: (i) pesticides exposed group (N=60), (ii) pesticide un-exposed group (N=42) and (iii) healthy controls group (N=50) were recruited for the study following the inclusion and exclusion criteria. The blood was drawn from the eligible subjects and Enzyme Immuno Assay (EIA) was performed to assess the 8-OHdG levels in serum. Appropriate statistical methods were used to analyse the study data. Assessment showed that pesticides exposed group has higher levels of serum 8-OHdG as compared to un-exposed group and healthy controls. Age and duration of exposure had an impact on the levels of serum 8-OHdG.The higher serum levels of 8-OHdG may be a marker for pesticides-induced oxidative DNA damage. Key words: pesticides; exposure; oxidative stress; 8-hydroxy-2’-deoxyguanosine (8-OHdG).
